Master List of Laundry Soaps

Sources of pure soap laundry powder or liquid

Always check ingredients first, manufacturers change product ingredients all the time.   I have compiled some of these along with other non-detergent products on an Amazon astore for convenience, and some of the links below go directly (most of the mfr links went bad).
A small % of astore purchases goes to SolveEczema if purchased through the link, on the order of $15/month).  Unfortunately, not all of these laundry products are available on Amazon so I can’t easily include most of them in the astore.

To save money or time, do it yourself!  There are many online recipes for laundry powder and gel using bar soaps, and various amounts of borax, washing soda, and baking soda.

Here are the pre-packaged products I found:

pure soap flakes

Pure Soap Flake Company
Laundry powder, soap flakes, soap bars







Pure Soap Flake Company
They have an unscented laundry powder which is just simple soap, baking soda, borax and washing soda.



cal ben seafoam laundry soap

Cal Ben Seafoam Laundry
25 lb. box

Cal Ben Seafoam Laundry Soap

More complicated list of ingredients than most of these, plus sprayed with citrus oil, but it’s essentially soap-based.  I have used this product successfully.




Zum Clean Laundry Soap












Zum Clean Laundry Soap
64-oz Sweet Orange on Amazon
Liquid laundry soap, various fragrances.  No unscented.




vermont soap

Savon de Marseille flakes

Savon de Marseille
Traditional French Soap

Savon de Marseille Soap Flakes
Marius Fabre Marseille soap flakes on Amazon
Traditional soap flakes.  Can be combined with washing soda and borax, especially in hard water.  (It may pay to shop around, these are expensive.  Their liquid soaps use minimal ingredients and pure olive oil, and are also an option combined with washing soda and borax.)


pure soap works laundry soap

Pure Soapworks Liquid Laundry Soap or Laundry Powder (Canada) 
This company seems to carry a full line of soap products.


Zote Laundry Soap Flakes

Pack of 8 (17.63oz) Zote laundry soap flakes on Amazon
Still the most popular laundry product in Mexico.  (From animal tallow.  Also contains fragrance and optical brighteners.  Despite it being soap, users must take care if allergy to fragrance or optical brighteners might be an issue.)


Grandma’s Laundry Soap

Grandma's Laundry Soap

Grandma’s Old-Fashioned Laundry Soap

Grandma’s laundry soap on Amazon

A lard-based soap flake product.  This appears not to have any dyes or unnecessary ingredients.  This company also sells a soap-based stain remover stick and bar soaps.  They seem to understand the difference between soap and detergent per the site.



Eczema, detergents, and bat white-nose syndrome?

When I originally wrote, I always understood that a medical study or publication would be necessary to bring the ideas into the medical mainstream.  I did the site because I wanted to help as many people as possible in the meantime.  

I have also always realized there are other implications to these ideas beyond eczema, but didn’t feel in a position to write about them.  I was moved recently by reading a Science News story about bat white nose syndrome, which is so lethal, the word “extinction” is being bandied about.  I spent weeks composing an email to a respected bat researcher who is on the forefront of trying to save these beneficial creatures.  I’m sure this is going to seem like it’s coming from left field, so it’s unlikely to make an impact.  But as with writing the site in the first place, I had to try.  

I’m posting the letter here, edited for clarity, as it again discusses some of some of the ideas underlying

Dear Dr. Reeder,

I have followed your work on bat white-nose syndrome in lay publications like Science News. I have for many years been concerned that something like this could happen to bats because of an unrecognized environmental influence that, if at issue, I’m surprised took even this long to cause such devastation.

I have to ask you to please bear with me while I explain.  There are so many preconceived notions to overcome about what I am about to say, there isn’t really an easy way to say it.

For 8 years now, I have run a noncommercial website with a novel approach to eczema and allergies that helps families ameliorate or eliminate their children’s eczema and other atopic manifestations like asthma without any treatment, by getting to the environmental cause.  Yes, I realize bats don’t get eczema, but please bear with me.  The site has been used by people all over the world, including doctors for their own families, and has inspired a green cleaning book.  Last year alone, even though I don’t do any advertising or optimization, the site had nearly 40,000 unique visitors and 130,000 page views/360,000 hits, plus many thousands more on the associated blog.  Around 80% of the visits are from bookmarks and direct links, only 20% from search engine links, meaning most visits are from people referring the information to each other and returning themselves.


Eczema from detergents,
plus infection Credit:

If you want to see a well-written, well-documented anecdotal demonstration of this, a mom in Georgia has been blogging about using my website to help her once severely eczematous son lead a normal life without treatment (that’s him on the right before she found my website):  Again, this does relate to bats, please bear with me.

Eczema, asthma, and allergy rates have risen precipitously in many nations around the world since WWII, affecting nearly every other child in some hotspots. Dogs and cats, by the way, face a concurrent increase in eczema and other atopic manifestations like allergies.  Most mainstream medical researchers acknowledge that even though there appears to be a genetic susceptibility, given the rapid rise, and how those who move from geographical regions with less eczema to regions with more eczema acquire eczema at the higher rates, the cause must be primarily environmental.

Normal skin, no treatment

People are using my website to not only eliminate their eczema, but also their asthma, allergies, and dry skin, in the way the underlying basis predicts.  The underlying problem is the way modern synthetic detergents — which are dramatically more hydrophilic and oleophilic than the surfactants (soaps) used by humans for thousands of years prior — affect the skin barrier, causing excess water loss and thinning of membranes.  The reason detergents cause such dramatic effects is not because, as is traditionally believed, washing products strip the skin of oils.  In my observation, it’s because residues that persist on the skin directly increase the permeability and cause excess water loss as a result, even just those residues that migrate from contact with clothing washed in detergent, or detergent-laden dust.  Ingested detergents on dishes and even in processed foods, and inhaled detergents in dust (which is predominantly skin cells and lint in modern indoor environments, in other words, full of detergents) affect lung and gut membranes as well.  The surprise was that ingested detergents also affect skin membranes.  In my experience, the eczema is expressed proportionally to permeability increases.

Everyone, not just those expressing eczema, appears to be affected and experiences degradation of the skin barrier and other membranes.  Only some people, especially children whose skin is naturally more permeable and absorbs more detergents (and proportionally so), experience the eczema more readily.  Detergents also facilitate antigen penetration of membranes and thus overall antigen load, and can negatively impact sensitive membrane healing times.

It is my belief — and I realize these are all just my ideas but they do happen to lead to real solutions for many, many individuals who could not find those solutions in standard approaches on the subject — that the expression of eczema is, under normal environmental conditions and in the absence of these modern exposures, a “healthy” signal from the immune system to the conscious brain when faced with too much allergen/antigen in the environment, under that immune system’s particular conditions at the time, in the same way that pain serves the nervous system (mostly as a warning to the conscious brain).  The classic interpretation of allergy is that the immune system becomes confused and attacks the body, but my interpretation is that allergens being similar to pathogens to the immune system, require more energy to differentiate between them.  If the immune system can “tell” the conscious brain to offload allergens to better and more accurately face a microbial threat, for example, allergy could confer a survival advantage.  Aeroallergens typically produce respiratory symptoms, contact allergens cause skin symptoms, etc.  There is a roughly linear relationship between eczema rates and atopy by nation, and in societies where there is very little of both, the rates of eczema can be very, very small, i.e., the triggering of that signal is uncommon and could be beneficial.

In other words, I believe the eczema itself is a signal that some people express, under certain genetic and physical conditions.  Eczema isn’t a problem that affects one person and never the next, there is a continuum, where more and more people are affected as the environmental cause increases.  Everyone has the potential to express this signal.  In severe atopic dermatitis, the inputs, feedback, skin barrier, immune response, and expression of the signal are all abnormal and out of control because of modern environmental influences, overwhelmingly, I believe, detergents.  The signal is expressed for some people as certain thresholds are crossed, for more and more people as the exposures increase.  Remove those influences, and people can be completely normal, without treatment of any kind.  In order to accomplish that, typically a whole household must make the changes, and inevitably, everyone in the household experiences surprising benefits — most notably to skin but also allergy — not just the person who had eczema.

Please continue to bear with me, this is absolutely relevant to bats.  It’s very important to realize that there can be very substantial physiological effects from very tiny exposures.  And in the presence of small amounts of water — sweat, for example, or other membrane surface dampness or condensation — the effect on permeability is dramatically amplified.

In the course of using the website to eliminate eczema, if properly implemented, it is a universal experience that everyone in a household undergoes a beneficial change in their skin, even if they don’t have eczema or atopy.  Over the course of about two months, the skin becomes completely different:  thicker, more supple, and less dry.  Most people are eventually able to wash with soap and stop using moisturizers.  This happens for anyone, for people who use the site just to eliminate dry skin.

It’s clear, too, from empirical observation, that many people with eczema are affected by fungal organisms (and sometimes bacterial) while the skin is compromised, and those areas must be treated to kill the fungal organisms before the skin will completely heal.  Research (with no cognizance of this detergent issue) also shows that people with eczema are more susceptible to infections on affected skin than people with skin conditions that also disrupt the skin, like psoriasis.  Research with detergents on sensitive eye membranes show they can substantially increase healing times.

Since fungal cells are more like mammalian cells than they are even like bacterial cells, and those fungal cells can replace mammalian cells, it’s necessary to be extremely careful in treating those “infections” or colonizations because if the fungal cells die off all at once, the result could be an alarming and even more compromising loss of skin, such as sloughing off of large surface areas and bleeding depending on how affected it is.  If antifungal treatment is ramped up very, very slowly over time, though, die-off is minimized and normalization of the skin can be achieved over time without the risks associated with sudden die off.  Fortunately, fungal organisms tend to grow slowly, so this process works better with fungal organisms than you might expect with bacterial.

Here’s why I believe this is important to bats and specifically to your work:  First of all, the obvious:  bats’ wings are mostly skin.  Bats (and frogs) live at that land-water/wet-dry interface, in other words, where they would constantly be affected by the small amounts of water that amplify the detergent effect on membranes I described above.  Although bats to my understanding stay in dry parts of caves, they do live in cool, dark, damp places where fungal organisms can be very opportunistic if a modern influence were to so fundamentally compromise bats’ evolved defenses.  In other words, bats and frogs would in theory be most affected by detergent pollution, the proverbial “canaries in the coalmine”.  It’s interesting that in Australia, Roundup was banned until the maker removed, not the poison, but the detergent in it which was killing frogs.

Detergents are ubiquitous outdoor environmental pollutants now, especially in aquatic environments.  Their use has been on the rise outdoors as well as indoors in recent decades.  They are readily absorbed (attached to, really) by living membranes.  Bats in particular would be susceptible to exposure, as bats eat a lot of insects, obviously, and presently virtually all pesticides and herbicides for large-scale use are mixed and sprayed with detergents in order to reduce surface tension and spread the active ingredients more evenly.  New biological controls intended to reduce poison use and highly target certain bad bugs without harming the good ones, if sprayed with detergents (as is almost certainly the case), may be having the unintended consequence of exposing bats to more ingested detergents as they consume non-targeted insects that have detergents on them.  Bats could also outright come into contact with sprays or dusts, or detergents in water, and it doesn’t take much.

If detergents affect bat membranes the way they do human skin – and I see no reason they wouldn’t – detergents would both degrade bat membranes (thinning the wings) and make them more susceptible to fungal colonization.  Ingesting detergents also appears to cause eczema and membrane degradation in human skin — difficult-to-correlate membrane degradation even in humans who do not express eczema — and can do so in very, very small quantities.  Although other mammals may not express eczema, which as I believe is an evolved signal/adaptation and not the direct effect of detergent contact irritation, the underlying basis for the skin barrier dysfunction would almost certainly extend to other mammals, whether they express eczema or not.  Since humans and presumably other mammals use endogenous surfactants in critical functions of life, including to control skin membrane permeability, it makes sense that exogenous detergents could throw a monkey wrench in this adaptation.  It’s also very possible that there is no adaptation that would allow for a survival advantage to bats by expressing this signal of eczema as there would be for larger mammals.  In other words, there is no reason to believe bats would experience any benefit from eczema as humans and perhaps even their pets would, so any corresponding genes would have died out long ago.  Nevertheless, bats (and frogs) would experience negative impacts to their membranes from significant exposure to exogenous detergent sources.

I want to reiterate that ingested detergents, even in small quantities, can cause surprisingly significant physiological effects.  The amount of detergent that penetrates the skin of a banana or shell of an egg from normal processing practices, if ingested, is enough to cause patches of skin changes in susceptible infants.  These are some of the most minor influences in a home today, in the most susceptible group — I am just pointing out that if other influences are effectively controlled, in the most susceptible (babies), even such minor influences can have visible effects.  How much more detergent are bats undoubtedly consuming and contacting relative to their body weight and skin surface these days?

I have witnessed infants go from clear skin to bubbly, itchy, severe-looking rash in 20 minutes just from contact with the clothing of an adult who was substantially detergent-free except for face wash or moisturizer containing detergents, with no direct skin-to-skin contact.  I have seen this even from an adult, in similar circumstances, simply leaning over a susceptible infant, without any direct contact.  If these children are removed from the exposure and washed immediately with ordinary soap (see my site for how “soap” is defined, very important) to remove detergents, reversal of even a severe rash to normal skin (provided the infant has been living in a substantially detergent-free environment already) can be just as rapid and stunning.

I think in order for researchers to truly figure out whether it’s possible to help the bats they are studying to recover, researchers probably need to remove that environmental influence from their labs and persons completely.  If researchers are not detergent-free, they are producing detergent-laden dust that would affect creatures as tiny as bats, with already compromised membranes, in ways most people could never imagine.  Understanding these influences from the detergent-eczema arena could shed light on how and why bats are being affected, and how to help them in new ways.  It’s not as difficult as it might sound to achieve results, but it’s necessary to really understand and these are my own novel ideas, not yet in the mainstream of eczema research.  But they are helping a great many people worldwide in the way the underlying ideas would suggest.

I want to propose to you that this line of inquiry is worth looking into, because if detergents are indeed an unrecognized factor in worldwide frog and bat population crashes, rescue of bats may be more effective, and the long-term solutions could be straightforward, if not simple.  People making newer biological controls for targeted insecticides may simply need to take care to use only surfactants which are no more hydrophilic than typical alkaline soaps, for example.

In one interview I read recently, you are quoted as saying, “For a long time, a lot of us — myself included — said fungal infections don’t kill mammals, so that can’t be what’s killing the bats.  But it turns out that because of the bat’s unique hibernation cycle and the nature of the fungus, it does kill them.  The big question now is:  Can we prevent extinction?”  You may be surprised to learn of a growing body of research discussing new kinds of fungal susceptibilities, colonizations and diseases in humans, especially children, because of modern influences.  Like you, researchers believed these microorganisms had no role in human disease — until a variety of new influences like chronic use of steroids or antibiotics — and I would personally add, detergents — created new susceptibilities especially in vulnerable populations.  Given what I have learned over the years about detergents and eczema, I think it’s highly likely that detergent pollution plays a central role in susceptibility of bats to fungal diseases.

Over the years, I have occasionally sent letters like this to researchers without response.  It’s very likely my letters just end up in spam folders, as I expect this one is likely to.  So I am posting it on my blog as well, in hopes that one of my readers may have a bat researcher in their lives with whom they can share it.  This letter also happens to explain the underlying concepts again which, if nothing else, also helps my readers.

I am moved by the specter of the extinction of these beneficial creatures; I hope this letter proves useful to you.  Thank you for taking the time to consider my input.  I wish you all the best in your work to save bats from this urgent threat.

Sammy, before beginning SolveEczema

I just want to share again a link to this blog, about a mom who was on a quest to cure her son’s eczema and ended up using   Sammy’s Skin – The Story of a Boy, His Eczema, and the Quest for a Drug-Free Cure.

Much of what I do with is try to figure out how to get people over all the typical barriers and myths so that they understand enough to do their own problem-solving and persist with the strategies to solve the eczema.  I heard from Sammy’s mom when she was in the middle of her quest, and given the many barriers, I really feared she wouldn’t be able to persist with the site, even though I thought her son would probably benefit.  Not only did she persist, but she has started a bulletin board where she is helping other families who want to use the SolveEczema site, and moderating with two other moms:

I have always wanted to start a bulletin board myself; I’ll be very honest that I think these dedicated moms are doing a better job at encouraging, answering questions, and creating a community than I would have.  We all learn from each other.

Happy Thanksgiving, everyone!

Detergents in (some) Water Softener Salt?!

Photo from by mokra

What? Detergents in water softener salt?!


Soaps work better, they clean better, in soft water than in hard water.   Soaps perform better than detergents in soft water — one reason detergents were invented in the first place was to perform across different water conditions including hard water.  Detergents perform better in hard water than soaps do , though nothing performs what I could call well in hard water, soap or detergent.

Because soaps perform so much better in soft water, I recommend mechanical water softeners to people who otherwise have hard water.  Soaps work better, it takes less time to wash out old detergents from clothing, it takes less soap by far to get things clean, white fabrics stay white and don’t grey as they do in hard water, and hair and skin stay soft.   It’s easier to keep bathroom surfaces clean without so much scale on surfaces.  There are many advantages.

As I mention on the website, several studies have looked at water hardness versus eczema, and found that people living in areas with harder water have more eczema.  For example,

Atopic eczema and domestic water hardness

Ecological association of water hardness with prevalence of childhood atopic dermatitis in a Japanese urban area,

As a result of these studies, a group in the UK did A randomized controlled trial of ion-exchange water softeners for the treatment of eczema in children.  In contrast to the studies above, which simply measured water hardness and correlated with eczema prevalence, here mechanical water softeners were installed in some homes and the results to the eczema of the children with and without assessed.  Participants were told not to change the way they bathed or washed their laundry.  The results:  No benefit was found from the softeners, although interestingly, over 50% of the parents chose to buy the water softeners at the conclusion of the study.

Given that the water softener study protocol asked families to maintain their washing and washing product habits through the trial, it’s not surprising to me that they found no benefit from the softeners.

What do users take from these studies?  Very little, because the study designs don’t take the type of washing products used by the families into account, and in the study of installed softeners, the researchers specifically asked families not to adjust the type or amount of products they used.  (They have eczema, they’re using detergents!)

I have recently become aware of a another potential concern for SolveEczema users.  SOME WATER SOFTENER SALTS HAVE DETERGENT ADDITIVES!

Additives help keep the ion-exchange resin in the softener clean, and prevent inconveniences like “bridging” of the salt, and since water softener companies are unaware of the connection between small amounts of detergent and eczema, and believe the amount of detergent introduced by the additives is small, they believe it’s all good.

But taking a look at the Morton web site, I found this frequently asked question (with answer):  “After using Morton water softening products why does my skin itch?  …Even though it is unlikely that the additives in the salt product could be the cause of the skin itch, you may wish to try a product with no additives, such as Morton®White Crystal® products or Morton® Potassium Chloride Pellets. …”

Because of the additives, Morton also does not recommend using the water softening salt with additives in aquariums.  As mentioned above, they do sell water softener salt products without additives, and I called their corporate office recently to suggest they pay attention to the issue of detergents and eczema, since much potential future growth in the water softener business will likely come from families whose kids have eczema (from detergents).

Another parent wrote to me with this information from the Cargill site regarding Diamond Crystal salt pellets with an additive called Softener Care:
What exactly is “Softener Care” additive?
The Softener Care™ additive is a surfactant called sodium hexametaphosphate. In the pellets, it provides added durability, thus reducing the tendency towards mushing and bridging which can interfere with normal softener operation.”

It appears that Diamond Crystal/Cargill also sells products without the additives.

Our local hardware store always sold only pure salt for the water softener, but when this came to my attention, my husband told me he had just bought a bag that was different because the hardware store stopped carrying the old kind we had been using.  Lo and behold, it had detergent additives in it!  Luckily, he hadn’t yet poured it.

It gets exhausting keeping after all the many sources of household detergents, but this one is particularly important to get right, since it would introduce low levels of detergents in the household water supply.

I still recommend water softeners for those wishing to try the strategies on, because of so many benefits to skin and household, and because it takes so long to get results with hard water — hard water results often are never as good as with soft water.  So, if you are trying to follow the site strategies —

Q&A: Reading Labels and the confusing business of telling soaps from detergents

I received a letter recently with a request to better explain how to find products that meet the SolveEczema site criteria.  I get product questions enough that I thought I’d just post my reply here on the blog:

My letter:

I’m glad the site helped!  I know it’s confusing to tell which products meet the site criteria and not — if it helps, I have difficulties evaluating product ingredients myself!  (Unfortunately, the majority of products available on store shelves do not meet the site criteria, which is why so many people have problems finding ones that do.)

First, you researched your daughter’s problem and implemented something that helps — so you are a problem solver, and that’s what’s important here.  I come across many moms who are very systematic, determined, and smart, many of whom have no science background whatsoever — and they’re as and sometimes even more effective than someone whose training might at first be a barrier to looking at the problem a new way. So don’t feel like it’s you.  It’s just the position we are all in because of what’s in our environment, how ubiquitous that influence is, and how poor the information we have is to assess it.

I have had friends who told me, “Just tell me what to use” — which works up to a point, but getting the best result takes understanding what is going on and problem-solving in your own environment.  Often people think they are detergent-free yet miss even very obvious influences until they do understand.

Plus, products are different everywhere — I get letters from all over the world — and companies change their products all the time.  I just got a letter from another mom who ordered some products from a company I recommended, Eco-Me, and there were sugar detergents in the products she received.  I looked on the company’s website, and they had different pages on their site for those same products with completely different ingredients.  I remember when I first checked them out, everything they made was okay per the site, but no longer.  They may be in the process of reformulating.  Worse, they have used the word “soap” in the INGREDIENTS list for something that is not a traditional soap.  It’s the first time I’ve seen “soap” used in the ingredients for something that isn’t a true traditional soap.  However, if you understand, you should be able to figure that out when you evaluate even those products.

One of the most important reasons to understand is for parents to really see the problem as environmental and not a “defect” in their children.  There’s a huge difference, psychologically, between needing a chronic treatment and knowing the problem isn’t you, especially for kids.

The video slideshow overview explains everything fairly simply, in case you haven’t already watched it.  You may want to take a look again at the slide showing the difference between soap and detergent chemical names, it may help.

So, everyone has trouble assessing ingredients.  I have trouble assessing ingredients.  If this were easy, more people would have figured it out.

The underlying principle is this:  I believe “normal” eczema and allergies are a signal from the immune system to the conscious brain, the way pain is for the nervous system.  Whether the “signal” is expressed or not depends on whether a certain threshold is crossed, and that depends to some extent on the state of the immune system, genetic factors affecting skin and immunity, environmental factors affecting skin (such as local humidity, but also whether the skin is damaged because of long-term exposure to detergents, etc), the state of the gut and whether certain proteins are crossing into the bloodstream (and, I suspect, necessitating increased circulating biological detergent to denature those proteins), etc.  But by far the greatest influence now comes from the effect of modern synthetic detergents, which (because of how they are designed) dramatically and unnaturally increase the permeability of skin.  In my experience, the expression of the eczema is proportional to the effect on the permeability.

Removing detergents is not very successful with water alone, residues are incredibly persistent.  As the site says, it’s necessary to use something else to get them out.  Plus, people need a way to get clean in the normal course of life.

So, what else can be used?  Something that doesn’t increase the permeability of the skin beyond a certain point.  The major class of washing products that work appears to be, empirically, traditional alkaline soaps.  Luckily, because they are made in such a narrowly defined way per the relevant characteristics of the end products, they’re pretty much all okay (provided the individual ingredients aren’t allergenic for a given person).

The rise in eczema, asthma/atopy around the world in the latter half of the 20th century has coincided with the increased use of detergents.  Many of the observations that led to the hygiene hypothesis take on new meaning when looked at in that light.  For example, people in many rural areas have less eczema than in urban areas.  One proposed interpretation is that people on farms are less clean and are around certain germs that challenge the immune system.  I’d make the separate observation that soapmaking is traditional in rural environments, farmers spend more time out-of-doors (instead of in indoor environments with the greatest exposure to detergents and detergent dusts).  Amish farm families have an even lower rate of eczema than farmers in the same regions; the Amish still make and use their own soap.

Anyway, back to the issue at hand…

As I describe in detail on the site, words like “soap”, “detergent”, “surfactant”, “emollient” and others, are used very differently in different consumer contexts.  Common definitions have changed over time.  I define the words in a way that allows people to get results with my site, and my definitions are definitely supportable on technical grounds.  However, that’s not how those words are necessarily used when labeling products you buy.

The word “surfactant” just means surface active agent — substances used to reduce the surface tension of water — and covers both traditional soaps AND detergents (by my definition of those words).  HOWEVER, on ingredients labels, the word “surfactant” is invariably used to describe synthetic detergents.  Often it is used to avoid using a name with more negative connotations for consumers.  Lots of products containing SLS or similar detergents describe them as “coconut-based surfactants”.

So, to be very technical about it, no, you don’t have to avoid all surfactants, because soap is a surfactant, but you probably do need to avoid anything LABELED as having a “surfactant” for the time being, because invariably it means it contains a synthetic detergent.

To use the site, you can use borax, baking soda, vinegar, or other non-surfactant washing products I mention.  And you can use any traditional alkaline soap (so long as you don’t have an individual allergy to the ingredients and it’s not so alkaline as to be badly drying).  There is a short list of the most commonly used soaps and their chemical names on my slideshow.  If the label says “saponified [oil]”, that’s soap, or if the label lists an oil and potassium or sodium hydroxide, and no detergents, that’s soap.  Castile soap is soap made with olive oil.  Fortunately, the number of pure soap products seems to be growing.

Sometimes products list only the oils in the ingredients, and it’s not clear whether the products are traditional soap or not.  In that case, if you want to try the product, it’s better to call or write the company first to verify what the product is.  Is it just oil?  Is it saponified oil? Or is it something else made from those oil ingredients (which would make it a detergent by my site definition).

Natural products companies in the last few years have begun to heavily use sugar detergents, which seem to be more mild than other syndets (a “syndet” is a synthetic detergent), and at first I cautiously recommended them.  But I’ve heard from too many people for whom they did not work, so I’ve conditionally withdrawn my recommendation and am hoping for a better sense of these over time.  (I generally suggest problem-solving only with products you can be very sure of, and experimenting with things like these later once you know what you may be dealing with.)

As I say on the site, check ingredients.  I do have one caveat, though.  I tell people to ignore the front label, and to read the ingredients label, which tends to be more accurate and precise.  The front of the product may say “soap” but the product may be entirely detergent.  Usually the ingredients label, however, will be more clear.  If it says something is a “saponified” oil or a “soap” it’s usually traditional alkaline soap.

IMPORTANT NOTE:  However, another mom brought to my attention recently those Eco-Me products I mentioned above, that used to all be non-detergent — they used the word “soap” on the label of their dish soap product for a detergent.  It’s the first time I’ve seen that.  The label (Suzy dish soap) includes:  ” Coconut-base Soap (Decyl Glucoside)” — “Decyl glucoside” is a sugar detergent.

Given the trend in the “natural” product industry, it’s probably a good idea to search the names of the most common sugar surfactants and know what they are.  You’ll generally see the roots of the words for sugar in the names (glucose <=> decyl glucoside).  And also to just know the chemical names of the most common soaps.

The only reason I mention charge properties (anionic, nonionic) is that soap is anionic, so if a surfactant ingredient is described as an amphoteric or nonionic surfactant, you know it’s not soap.  However, many harsh detergents are anionic, too — sodium lauryl sulfate is anionic, as are many problematic syndets.

Additionally, it’s important to realize just how problematic hard water can be. Few people really appreciate just how much of a factor water hardness is to getting results.  Soaps clean so much better in soft water, far less product can be used, and everything rinses better.  Skin and hair feel so much better, too.  Soaps don’t work very well in hard water.  Nothing rinses well.  Very hard water can mean the detergent removal process effectively takes months rather than weeks or days.  Many if not most of the people who contact me with problems, it turns out, have hard water.

I do my best to give a list of products that will work, and I check the ingredients very carefully.  But most companies that sell soap products also sell some or many products that don’t meet the site criteria.  Products change, and there’s no way for me to keep up on everything.  I go to a great deal of trouble to describe how to figure out products on the site, but unfortunately, the difficulty is just because of the situation we are all in, it’s not you, and it’s not for a lack of scientific skills.

I know you asked for a “dumbed down” explanation; please let me know if anything is still unclear.  It will help me know what I need to do a better job explaining for the book.

I hope it helps.  Good luck to your family and your baby for a regular no-eczema childhood!




The SolveEczema view on dry skin

I am reposting a part of reply I just wrote to a comment, since not everyone reads the comments (and I tend not to even read what comes in frequently, because of all the spam).  It covers the issue of myths about dry skin, from my perspective:

With eczema, dryness is almost a separate issue. You won’t hear that from anyone else, because the accepted view is that dryness causes the eczema, which I have found in my experience of actually eliminating eczema is not the case. I say “almost”, because dryness is a modulator that can make people more susceptible with lower levels of detergent exposure, as described on the site. I hear (more than I care to think about) from users who use products I find unacceptably drying, who are nevertheless happy because they get rid of the eczema.

   I’m going to write more about the dryness issue in my book – which, thanks to the crowdfunding, I can describe as “upcoming”! My bar soap experiments ended up bringing me to an entirely different idea about dry skin and how products cause it than I expected. Perhaps given the experience with detergent, I shouldn’t have been so surprised.

   Again, I believe dryness alone isn’t the reason for the eczema. After seriously experimenting with over a hundred different bar soaps, I also eventually came to the conclusion that dryness associated with the use of the products was not the result of stripping the skin of oils. I came up with a general rule and gave it a name (with some apologies for the presumption, but in hopes of making it more memorable):

   Lumsdaine’s Law: For most people, under most conditions, eczema and dry skin are more the result of what is left on the skin than what is stripped from the skin by washing.

   Adding too many moisturizing ingredients to soaps seems to backfire. We all think – as I thought before I did these experiments – that skin gets dry from washing because oils are removed, so adding moisturizing ingredients should help, right?  As with so many things, our assumptions trip us up.

   What I found is that immediately after washing with a “moisturizing” product, the skin feels soft – just as it feels soft right after washing with water or moisturizing with a creamy, absorbed moisturizer – but if I only used that product (which I was fastidious about doing while I tried each soap), over time, my hands became horribly dry. It happened over and over again with different “moisturizing” products, the opposite of what I expected.

    The surprise came when I got fed up with how dry my hands were from one product and just went back to my regular soap before my “trial” was over. My hands went back to normal almost immediately, far faster than could be explained by the typical view of how they became dry and how they might have normalized. I was able to repeat this with other products – which led to the lightbulb moment.

    I describe this in my talk – water, alone, a small layer of water on the skin, increases the permeability. Not enough to create eczema, but enough that if one, say, doesn’t dry the skin well enough after washing in the winter (with all the dry air), the hands chap. Increased permeability leads to water loss, leads to dry skin. I warn about absorbed, creamy (what I call “emollient”) moisturizers in my site, in part because they seem to create these same conditions. The skin feels more hydrated immediately after applying – just as it does with small amounts of water, right in the moment – but over time, the skin loses water (among other things). I think this is what is happening with very “moisturizing” soaps. (By the way, this is also why I recommend drying well, with a soap-washed towel, after a shower, NOT patting lightly and moisturizing over too much water – the opposite of the traditional recommendation.)

   I’m not saying some moisturizing ingredients aren’t good or are always going to create these conditions. One of the most lovely soaps I have ever used is the Luxo Banho Creme, which has sweet almond oil in it. But overusing moisturizing ingredients – which results in the kinds of products that make the skin/hands feel very moisturized immediately following usage, perhaps to the point that they don’t even feel clean – seems to create the conditions that lead to water loss over time and dry skin. The Luxo Banho – and every soap I have used that I consider the best – leaves the skin feeling clean and normal, not overly moisturized. On the other end of the spectrum, I think soaps can be drying if saponification is too complete and the end result may thus be far too alkaline – there’s a couple of products where I believe that may be the case – but that’s just a guess.

   Sadly, people with dry skin buy the “moisturizing” products which are in turn going to make their dryness worse, and assume it’s about their skin, not the products they are using!

Eczema Baby Scratching – Now Not Scratching
Eczema itches. Quality of life studies say even mild eczema can be as miserable as severe eczema, because no one sleeps. Babies don’t sleep, siblings don’t sleep, parents don’t sleep. It affects health and development. None of the studies quite hits home like this 2-minute video, sent to me by a mom who used the web site to help her son. I’ve edited out a long segment where baby Zack just digs at his neck, but it’s still hard to watch. Stick with it ’til the “after” photo, though (note: it’s silent, there’s no music):

Please help me to help more babies like this one. If you can, please make a donation to my crowdfunding project. The hope is to fund a medical study, but that level of funding would take high visibility on the crowdfunding website. If you can’t afford much, even $1 will make a huge difference in whether the project gets the visibility to attract other contributors, and you can keep your name and amount anonymous. You can donate at:
It ends February 29, just weeks away. Thanks so much for all the moral support and support so far!


When We Don’t Know What We Know

We know this stuff, and yet, why don’t we add it up?

Even my sleeping bag label tells me to wash it in mild “non-detergent soap,” because the makers know the high-tech fabric will lose its water repellency — become more permeable — from detergent residues.

Some researchers use detergents for transdermal drug delivery (getting drugs to absorb through the skin).

detergent pollutionHere’s something I just stumbled across on an environmental company’s web site:

“Detergents also add another problem for aquatic life by lowering the surface tension of the water. Organic chemicals such as pesticides and phenols are then much more easily absorbed by the fish. A detergent concentration of only 2 ppm can cause fish to absorb double the amount of chemicals they would normally absorb…”  (Photo of detergent pollution thanks to U.S. Fish and Wildlife Service.)

It’s not difficult to see that under such conditions, the skin is also a less capable barrier against pathogens.

Lastly, here’s a detailed and alarming study looking at concentrations of synthetic detergents and pesticides in surface and groundwater in India:  “The synthetic detergents (or surfactants) and pesticides are the two most common group of chemical compounds that are increasingly being used in modern civilization. Surfactants are common contaminants of aquatic environments due to their large consumption in all types of washing and cleaning operations”. [NC Ghose, D Saha, A Gupta, Synthetic Detergents (Surfactants) and Organochlorine Pesticide Signatures in Surface Water and Groundwater of Greater Kolkata, India, J. Water Resource and Protection, 2009, 4, 290-298 doi:10.4236/jwarp.2009.14036 Published Online October 2009.]

I could go on.  We know all this stuff, and yet … it’s as if we don’t remember the minute we’re in a different sphere of life or work.
