We know because we spent two years trying to build something better for our own children — and discovered the industry had been asking the wrong question the entire time.
The question the industry asks: how do we make sulfate-free soap lather like conventional soap?
The question we asked: does soap need to lather at all to remove germs effectively?
The CDC answered it for us. Technique drives germ removal — not surfactant strength. The chemical aggression behind conventional soap's foam was never what protected your family. It was the mechanical process all along.
That single finding changed everything about how we formulated NOWATA.
Most sulfate-free formulas missed it entirely. They swapped SLS for a milder surfactant, kept the same stripping mechanism, and called it a solution. Same barrier cost. Cleaner-sounding label.
We replaced the mechanism entirely. Two years of formulation. One Swiss lab test. One result: 99.9% germ removal — zero sulfates, zero surfactant aggression, no sink required.
What this page covers:
What the science actually says about sulfate-free soap and germ removal
Why most sulfate-free formulas still fall short of solving the real problem
How to identify genuinely effective sulfate free hand soap cleansing on a label
What two doctors learned building a soap that protects the skin barrier and removes germs — without choosing one over the other
The short answer: yes, sulfate-free hand soap can be more effective. The longer answer: effectiveness depends entirely on what replaced the sulfates — and whether the brand replaced the ingredient or the mechanism.
Most brands replaced the ingredient. We replaced the mechanism. Here's what that difference looks like.
TL;DR Quick Answers
sulfate free hand soap
Sulfate-free hand soap removes SLS and SLES — the synthetic surfactants that strip the skin's natural moisture barrier while creating lather. But removing sulfates is the starting point, not the solution.
What most brands won't tell you:
"Sulfate-free" has no FDA definition and requires no pre-market testing or verification
Most sulfate-free formulas replace SLS with a different surfactant using the same chemical stripping mechanism
The CDC confirmed decades ago that technique — not surfactant strength — drives germ removal. The industry never built around it.
What genuinely sulfate-free hand soap should deliver:
A cleansing mechanism that removes contaminants without disrupting the skin barrier
Third-party verified performance data — not unregulated front-label claims
Full ingredient transparency — every ingredient published and independently verifiable
An answer to: what replaced the sulfates and why is it better?
What we built at NOWATA:
100% plant-based clumping technology that physically lifts dirt, oil, and germs away from skin
Zero sulfates, zero parabens, zero alcohol, zero surfactant aggression
99.9% germ removal — Swiss lab verified
No sink, no rinse, no barrier cost
80–100 uses per tube
Who needs it most:
Children with eczema-prone or sensitive skin
Healthcare workers and teachers washing hands 20+ times daily
Families who need effective hand hygiene that works anywhere — not just at a sink
The bottom line: sulfate-free matters. The mechanism that replaces sulfates matters more. Most brands changed the label. We changed the mechanism in hypoallergenic hand soap for a cleaner wash that supports truly gentle, family-first skin.
Top Takeaways
Here's what every family should walk away knowing after reading this page.
Sulfate-Free Hand Soap Can Be More Effective — But Only If the Right Question Was Asked.
CDC confirms technique drives germ removal — not surfactant strength
Most sulfate-free formulas swapped the ingredient — not the mechanism
Effective means replacing chemical stripping with physical removal
NOWATA result: 99.9% germ removal — zero sulfates, no sink required
"Sulfate-Free" on a Label Is Unverified Before It Reaches You — Every Time.
FDA has no authority to approve cosmetic claims before products hit shelves
"Sulfate-free," "gentle," "natural," "clean" — no federal definition, no testing, no proof
The ingredient list is the only tool that tells you what's actually in the formula
Ask every brand: what replaced the sulfates — and was it tested?
31.6 Million Americans Have Eczema. For Many, the Soap Is the Problem — Not the Skin.
9.6 million affected are children under 18
Childhood eczema rose 60% between 1997 and 2018 — while "gentle" product lines expanded alongside it
Most families were never told surfactant-based cleansers contribute to barrier damage
Sensitive skin is often a formulation problem wearing a skin condition diagnosis
The Sink Has Always Been Optional. The Industry Just Never Built Around That.
Standard faucet: 2 gallons per minute
CDC-recommended 20-second wash: nearly 1 gallon per wash
The moments hand hygiene matters most rarely happen at a sink
NOWATA eliminates the rinse step — saves up to 2 gallons per use — works anywhere
We Built NOWATA Because the Answer Existed — the Industry Just Wasn't Motivated to Find It.
Two doctors. Two years of formulation. One Swiss lab test.
CDC validated physical removal for decades — no soap brand built around it
"Gentle vs. effective" was never a scientific conclusion — it was a design limitation
Effective hygiene and an intact skin barrier were never opposing goals — they only looked that way when the formula was never designed to serve both
What the Science Actually Says About Sulfate-Free Soap and Germ Removal
Most people assume stronger lather means better germ removal. The data says otherwise.
CDC research confirms handwashing effectiveness is determined by technique — the mechanical friction of washing — not by the chemical strength of the surfactant. What this means in practice:
A well-formulated sulfate-free soap can remove germs as effectively as conventional soap
A poorly formulated sulfate-free soap can fail at both — ineffective cleansing and barrier damage
The surfactant isn't doing what most people think it's doing
What we confirmed during NOWATA's development: after two years of formulation and independent Swiss lab testing, a plant-based clumping mechanism with zero surfactants achieved 99.9% germ removal. The lather wasn't necessary. It never was.
Why Most Sulfate-Free Formulas Still Fall Short
Removing sulfates was the right diagnosis. What most brands did next was the wrong treatment.
The pattern we saw reading hundreds of competitor labels:
SLS removed from formula
Milder surfactant added in its place — cocamidopropyl betaine, sodium cocoyl isethionate, sodium lauroyl sarcosinate
"Sulfate-free" printed on the front label
Same chemical stripping mechanism — still intact underneath
The result: a formula that's marginally gentler on the skin barrier but still dependent on surfactant aggression to cleanse. Still requires thorough rinsing to complete contaminant removal. Still costs the skin barrier something every time it's used.
What no one stopped to ask: is surfactant-based cleansing the right model at all?
We asked for it. The answer took two years to build.
How Germ Removal Actually Works — and Why the Mechanism Matters More Than the Ingredient
Understanding why sulfate-free can outperform conventional soap requires understanding what's actually happening during effective handwashing.
Two cleansing models:
Chemical removal — surfactants like SLS chemically disrupt the membrane of microorganisms and strip contaminants from skin through chemical bonding. Effective when rinsed thoroughly. Costly to the skin barrier with repeated use.
Physical removal — contaminants are physically bound and lifted away from the skin surface through a clumping mechanism. No chemical disruption of the skin barrier required. No rinsing needed to complete the removal process.
What NOWATA's plant-based clumping technology does:
Binds physically to dirt, oil, bacteria, and viruses on contact
Lifts contaminants away from the skin surface completely
Leaves the skin barrier intact — no stripping, no moisture loss
Works without water — the physical removal mechanism doesn't require rinsing to be complete
Swiss lab result: 99.9% germ removal using physical removal alone. No surfactants. No barrier disruption. No sink.
The mechanism matters more than the ingredient because the ingredient is just one expression of the mechanism. Replace the ingredient without replacing the mechanism and you haven't solved the problem — you've repackaged it.
What Genuinely Effective Sulfate-Free Hand Soap Looks Like
After two years of formulation and eighteen months of reading competitor labels, here's what we know separates effective sulfate-free soap from effective-sounding sulfate-free soap:
Effective sulfate-free soap:
Replaces the cleansing mechanism — not just the surfactant
Achieves verified germ removal through third-party testing
Maintains or improves skin barrier integrity with repeated use
Performs without requiring perfect rinsing technique to complete contaminant removal
Publishes full ingredient transparency — every ingredient, independently verifiable
Effective-sounding sulfate-free soap:
Swaps SLS for a milder surfactant with a less recognizable name
Makes germ removal claims without third-party data to support them
Adds moisturizing ingredients to offset barrier damage the formula still causes
Relies on unregulated front-label claims — "natural," "gentle," "plant-based" — that carry no FDA definition
Cannot clearly answer: what replaced the sulfates and why is it better?
The difference isn't always visible on the front of the bottle. It lives in the ingredient list — and in whether the brand behind the formula can explain what it built and why.
Who Benefits Most From Genuinely Effective Sulfate-Free Hand Soap
The CDC confirmed hand dermatitis as the second most common nonfatal occupational illness in 2020. The NEA puts chronic hand eczema lifetime prevalence at 14.5% of the general population. These numbers represent real people washing their hands with formulas that are quietly working against them.
The people with the most to gain from a genuinely effective sulfate-free formula:
Children with eczema-prone or sensitive skin exposed to soap multiple times daily
Healthcare workers washing hands more than 20 times per day — where barrier damage compounds with every wash
Teachers and food service workers with near-constant soap exposure throughout the workday
Parents managing frequent handwashing during bottle prep, diaper changes, and meal routines
Anyone who has been told they have sensitive skin and has never been told to question the soap
What these groups share: they need hand hygiene that works consistently — without a skin barrier cost they keep paying every single day.
The One Question Every Sulfate-Free Label Should Be Able to Answer
We built this standard into NOWATA's development before we built anything else.
The question: what replaced the sulfates — and why is it better?
If a brand can't answer that clearly on its label, its website, or its formulation story — the "sulfate-free" claim is doing more work for marketing than for your family's skin.
Our answer:
We replaced sulfates with a plant-based clumping technology that physically removes contaminants without surfactant aggression, works without a sink, and leaves the skin barrier intact. We verified that claim through independent Swiss lab testing — not because the law required it, but because we were building this formula for our own children first and held it to the standard we'd apply to anything they use.
That's what effective sulfate-free hand soap looks like. Not a better-labeled version of the same formula. A fundamentally different mechanism built around what the science actually supports, and what eco-friendly soap does best: protect skin while keeping cleanliness standards high.
"Most people searching 'is sulfate-free hand soap effective' are really asking a different question: why do my hands still crack after I switched? We asked the same question about our own children. What we found after two years of formulation wasn't a better surfactant — it was evidence that the entire cleansing model was the problem. Surfactant-based soap, sulfate or otherwise, is built around chemical stripping. Every germ it removes costs the skin barrier something. We stopped accepting that trade-off the moment we understood it well enough to engineer around it. NOWATA doesn't clean despite being sulfate-free. It cleans more completely because we replaced the mechanism that made sulfates necessary in the first place."
Essential Resources
When we built NOWATA, we didn't start with a formula. We started with these resources. We're doctors and parents — and when our own children's hands cracked after every wash, we did what any science-minded family would do: we dug into the research. These are the seven resources that shaped every formulation decision we made. We think every family evaluating a sulfate-free hand soap label should read them too.
1. CDC: The Research That Proves Lather Has Nothing to Do With Clean Hands
Here's something the soap industry has never acted on: the CDC confirms that mechanical technique — not surfactant strength — drives germ removal. Foam isn't what's protecting your family. It never was. This is the foundational finding that changed how we thought about what NOWATA needed to do — and why we stopped trying to replicate lather entirely.

2. FDA: Why Every "Sulfate-Free" Claim on a Hand Soap Label Is Unverified Before It Reaches You
Before we wrote a single word on NOWATA's label, we read this. The FDA confirms it has no authority to approve cosmetic claims before products go to market. That means "sulfate-free," "gentle," "natural," and "clean" reach store shelves on a marketing decision alone — no federal verification, no required testing, no regulatory definition. Every family reading a hand soap label should read this resource first.

URL: https://www.fda.gov/cosmetics/cosmetics-labeling/cosmetics-labeling-claims
3. FDA: The Ingredient Listing Rule That Tells You More Than Any Front Label Claim
Marketing isn't regulated. Ingredient lists are. FDA regulations require cosmetic ingredients to be listed in descending order of concentration — meaning the first five ingredients reveal most of what any formula actually contains. This is the first tool we applied when reading every competitor formula before building NOWATA. It's the most practical skill any family can develop for evaluating what's actually in their soap.

4. EPA: The Government Finding on SLES That Most "Sulfate-Free" Brands Hope You Never See
When we investigated whether SLES was a safe swap for SLS, this is where the research led us. The EPA's formal risk evaluation documents 1,4-dioxane — a confirmed byproduct of SLES ethoxylation — as a contaminant in consumer soaps and detergents. This is one of the primary reasons we didn't swap one sulfate for another. We eliminated the mechanism entirely and built something different from the ground up.

5. National Eczema Association: The Statistic That Reframes What "Sensitive Skin" Actually Means
Our kids had skin reactions to conventional soap. We thought we were unlucky. Then we saw the numbers. The NEA documents the lifetime prevalence of chronic hand eczema at 14.5% of the general population — nearly 1 in 7 people. For a significant portion of that 14.5%, this isn't a skin condition. It's a formulation problem the label never disclosed. We built NOWATA for the 31.6 million Americans with eczema — starting with our own two kids.

6. CDC/NIOSH: Why the Most Common Occupational Skin Disease in America Is Caused by Everyday Cleaning Agents
NIOSH identifies contact dermatitis as 90 to 95% of all occupational skin diseases in the U.S. Among the mild irritants named as causes: water, detergents, and weak cleaning agents. Not industrial chemicals. The two things present in every conventional handwashing interaction. This is the resource that confirmed for us that the industry had been treating the symptom — not the cause. We decided to treat the cause.

URL: https://www.cdc.gov/niosh/skin-exposure/about/index.html
7. NIH/PubMed: The Molecular Proof That Skin Barrier Damage From Surfactants Is Structural — Not Cosmetic
We're scientists at heart. When our children's hands cracked, we needed more than anecdotal evidence. This peer-reviewed clinical study documents how surfactants like SLS disorganize the intercellular lipid structure of the stratum corneum at the molecular level — confirming that barrier disruption is a measurable structural event, not a marketing claim. This is the science that convinced us that removing the surfactant from the ingredient list wasn't enough. We needed to replace the mechanism that made it necessary in the first place.
Source: National Institutes of Health — PubMed
These seven medical and government resources shaped how we evaluate every sulfate-free hand soap formula, grounding our decisions in evidence the same way air ionizers are assessed through measurable environmental impact and verified performance standards.
Supporting Statistics
We are doctors. We follow evidence. Before we made a single batch of NOWATA, we followed the data until it told us something the industry had stopped asking about. These are the four statistics that changed how we formulated — and why they matter to every family questioning whether sulfate-free hand soap actually works.
Stat 1: CDC Confirms Handwashing Reduces Diarrheal Illness by 23–40% and Respiratory Illness by 16–21%. The Mechanism Doing the Work Is Not Surfactant.
The most important statistic the soap industry has spent decades ignoring.
What the CDC confirms:
Proper handwashing reduces diarrheal illness by 23–40%
Proper handwashing reduces respiratory illness by 16–21%
The driver of those outcomes: mechanical technique — not surfactant strength
What this means in practice:
Foam is a sensory experience — not a hygiene outcome
Surfactant aggression is not what's protecting your family
The mechanism driving germ removal is physical — and we could engineer around that
What the industry did with this finding: kept building formulas around surfactant strength and calling the lather proof of efficacy.
What we did: spent two years building a plant-based clumping mechanism around the physical removal principle the CDC had already validated.
Swiss lab result:
99.9% germ removal
Zero sulfates
Zero surfactant aggression
No sink required
The research didn't just confirm our approach. It told us the industry had the answer for decades and chose not to act on it. We didn't have that option. We were building this for our own children first.

Stat 2: 31.6 Million Americans Have Eczema. 9.6 Million Are Children. Most Are Still Using the Soap That's Contributing to the Problem.
When we saw this number, we didn't think about market size. We thought about our own children's hands — and every parent we'd spoken to during development who said what we had already lived: they tried every gentle formula on the shelf. None of them fixed it.
The scope of the problem:
31.6 million Americans have some form of eczema
9.6 million are children under 18
One-third of those children have moderate to severe disease
What the statistic doesn't capture:
How many were told it was just sensitive skin
How many switched to "natural" versions of the same surfactant mechanism
How many never knew the ingredient damaging their skin barrier was in their daily soap
What eighteen months of reading competitor labels confirmed:
The "gentle" product category grew alongside the eczema epidemic
Better-sounding labels — same stripping mechanism underneath
What two years of formulation confirmed: for a significant portion of those 31.6 million, this isn't a skin condition. It's a formulation problem. The skin barrier isn't breaking down because of genetics alone. It's breaking down because the soap was never designed to protect it.
We built NOWATA for those families — starting with our own two kids. Their hands told us what the data confirmed.

Stat 3: A Standard Bathroom Faucet Runs at 2 Gallons Per Minute. A 20-Second Handwash Uses Nearly 1 Gallon. Most Families Never Question Whether the Sink Should Be Required at All.
Dr. Yalda's biomedical engineering background meant we approached every design constraint with data. When we looked at EPA water figures during development, we weren't looking for a sustainability angle. We were asking whether the sink itself was a barrier to the problem we were trying to solve, the same way an air purifier and ionizer supports cleaner air by improving the environment at the source.
The water math:
Standard bathroom faucet: 2 gallons per minute
CDC-recommended 20-second wash: nearly 1 gallon per wash
Family of four, 8 washes each per day: thousands of gallons annually — just for hand hygiene
The insight the water data pointed us toward — one the industry had never acted on:
The sink is the single biggest barrier to consistent hand hygiene in real life
Every conventional formula assumes access to running water
Families in cars, classrooms, trails, and between meetings don't fail at hand hygiene because they don't care — they fail because the mechanism requires infrastructure they don't always have
What we did about it:
Eliminated the rinse step from NOWATA's clumping mechanism entirely
Result: up to 2 gallons saved per use — not as a marketing claim, as a design outcome
Clean hands no longer conditional on location
The EPA data didn't inspire a marketing claim. It confirmed an engineering requirement we had already committed to.
Stat: Standard bathroom faucet runs at 2 gallons per minute; CDC-recommended 20-second handwash uses nearly 1 gallon per wash

Stat 4: Childhood Eczema Prevalence Rose From 7.9% in 1997 to 12.6% in 2018. The "Gentle" Product Category Grew in the Same Period. No One Connected the Two.
This is the statistic we sat with longest during development.
The numbers:
Childhood eczema prevalence: 7.9% in 1997
Childhood eczema prevalence: 12.6% in 2018
That's a 60% increase — over two decades of expanding "gentle" and "sensitive" product lines
The question the industry never answered: if the sensitive skin product category grew alongside the sensitive skin crisis — what exactly was it solving?
What we found when we looked closer:
"Gentle" formulas still containing surfactants with documented irritation profiles
"Natural" and "plant-based" claims applied to ingredients that still strip the moisture barrier
No third-party performance data connecting formula gentleness to actual skin barrier outcomes
A regulatory gap the FDA confirms: no pre-market verification required for any of these claims
What that 60% increase told us as doctors and parents:
The industry had been responding to the sensitive skin crisis with better-sounding labels
Not better mechanisms
Not independently tested formulas
Labels
Our response:
Zero sulfates, parabens, and synthetic fragrances
Physical contaminant removal — not chemical stripping
Independent Swiss lab testing — not because the law required it, but because our children were the first ones using it
The statistic told us the problem was getting worse. The gap in the industry told us why. NOWATA is our answer to both.
Stat: Childhood eczema prevalence rose from 7.9% (1997) to 12.6% (2018); chronic hand eczema lifetime prevalence estimated at 14.5% of the general population

Final Thought & Opinion
Our honest opinion after two years of formulation, eighteen months of reading competitor labels, and a combined thirty-plus years of clinical and biomedical training:
The sulfate-free hand soap category solved the wrong problem — and convinced an entire generation of families it had solved the right one.
We know because we were those families first.
What We Believed Before We Started Formulating
Before NOWATA, we were parents doing what every conscientious parent does:
Reading labels
Switching to "gentle" formulas
Buying fragrance-free versions of the same products
Watching our children's hands crack after every wash — telling ourselves we hadn't found the right formula yet
What we didn't know:
There was no right formula — because the mechanism was the problem
"Sulfate-free" had become a label decision, not a formulation decision
The FDA confirmed no pre-market verification was required for any of it
The CDC had already validated the physical removal principle we needed — and the industry had never acted on it
The moment we understood the mechanism was the problem — not just the ingredient — everything changed. That's when NOWATA stopped being a product idea and became the only logical conclusion.
What We Saw That the Industry Didn't Want Us to See
During eighteen months of reading competitor labels, we looked for one thing: evidence that brands had replaced the mechanism, not just the ingredient.
What we found instead:
Surfactant substitution dressed as innovation — SLS removed, equally aggressive alternatives added, "sulfate-free" printed on the front
Unverified claims filling regulatory gaps — "natural," "gentle," and "plant-based" requiring no testing, no definition, no proof
Moisturizers added to offset damage the formula still causes — treating the symptom of barrier disruption while perpetuating the mechanism causing it
No third-party performance data — anywhere — not on labels, not on websites, not in formulation stories
We weren't shocked. We were frustrated. And frustration, for two doctors who understand the mechanism, is a powerful formulation motivator.
What the Data Told Us That the Labels Never Would
What the research confirmed as a pattern:
The people most harmed by conventional soap are the ones washing most frequently
The "gentle" category grew alongside the skin barrier crisis it claimed to address
The sink requirement was limiting hand hygiene compliance more than any formula ingredient
Physical removal was the validated mechanism the entire industry had access to — and never used
What the data couldn't tell us:
What it feels like to watch your child wince at the sink every morning before school
What it feels like to be a physician who understands the biochemistry — and can't find a formula that addresses it
What it feels like to take two years building something from scratch, send it to a Swiss lab, and see 99.9% germ removal on a formula with zero sulfates and zero surfactant aggression
That last part changed us. Not because it validated our chemistry. Because it confirmed the question we asked in the first place was the right one.
Our Honest Opinion on Where the Industry Goes From Here
Three things about the sulfate-free category most brands won't say publicly:
Most sulfate-free soaps are a label upgrade — not a formulation upgrade. The mechanism is identical to conventional soap. The ingredient list is cleaner. The skin barrier outcomes are marginally better at best.
The "gentle vs. effective" trade-off is manufactured — not real. The industry created it because surfactant-based cleansing required it. Physical removal doesn't. We proved it. The lab data proves it. The trade-off was never a scientific conclusion — it was a design limitation the industry accepted as permanent.
Waterless hand hygiene is the most underutilized public health tool available. The CDC says effective handwashing requires 20 seconds at a sink. Most moments when hand hygiene matters most — playgrounds, car rides, lunchboxes, between patients — don't happen at a sink. A formula built for how families actually live isn't a convenience product. It's a compliance solution.
The Bottom Line
We are not neutral observers of this industry. We are two doctors who got frustrated enough to build something the industry said didn't need to exist — and transparent enough to tell you exactly why.
What the research told us:
The right mechanism was available
The data validated it
The industry had access to both — and chose not to act
What we chose:
Physical removal over chemical stripping
Verified performance over unregulated claims
A formula built for our children first — then brought to yours
"Sulfate-free" should mean the barrier disruption problem has been solved. Not repackaged. Not softened. Solved.
That standard didn't exist when our children needed it. We built it anyway.
FAQ on Sulfate Free Hand Soap
Q: Is sulfate-free hand soap actually effective at killing germs?
A: Yes — but not in the way most sulfate-free formulas deliver it.
What we discovered during two years of formulation:
CDC confirms technique drives germ removal — not surfactant strength
Lather was never the active ingredient — it was always the mechanism
The industry never built around that finding — we did
How the three cleansing models compare:
Conventional soap: chemically strips contaminants — costs the skin barrier every time
Most sulfate-free formulas: milder surfactant name — identical stripping logic underneath
NOWATA: plant-based clumping technology — physically lifts contaminants away — no surfactant, no stripping, no sink
What that difference produced:
99.9% germ removal — Swiss lab verified
Zero sulfates — zero surfactant aggression
No compromise between effectiveness and skin barrier protection
We didn't remove the irritant and hope the formula still worked. We built a mechanism where the irritant was never necessary in the first place.
Q: What does "sulfate-free" actually mean on a hand soap label — and does it guarantee a gentler formula?
A: It confirms one thing: SLS and SLES are absent. That's where the guarantee ends.
What we learned reading eighteen months of competitor labels:
One surfactant removed
A different surfactant added — less recognizable name, same stripping logic
"Sulfate-free" on the front — barrier disruption continuing underneath
What "sulfate-free" should mean but rarely does:
Cleansing mechanism replaced — not just the ingredient
Third-party testing confirming germ removal and skin barrier outcomes
Every ingredient published and independently verifiable
The question every brand should answer clearly:
What replaced the sulfates?
Why is it better?
Where is the data that proves it?
If a brand can't answer those three questions — it hasn't solved the problem. It's repackaged.
Q: Who is most at risk from sulfates in hand soap?
A: Anyone washing regularly is exposed. The people we think about most when we formulate:
Children with eczema-prone skin washing before every meal
Healthcare workers exceeding 20 handwashes per day
Teachers and food service workers with near-constant soap exposure
Parents managing bottle prep and diaper changes around the clock
Anyone told they have sensitive skin who has never been told to question the soap
How most families find out — not from a label:
Cracked knuckles every winter
A child who cries at the sink
A dermatologist visit ending with a prescription — no mention of the formula causing the problem
What the data confirms:
31.6 million Americans have eczema — 9.6 million are children
Childhood eczema rose 60% between 1997 and 2018
NIOSH identifies detergents and weak cleaning agents among the named causes of the most common occupational skin disease in the U.S.
We heard these stories throughout development. We had lived our own version before we saw the numbers. The skin wasn't the problem. The soap was. For millions of families — it still is.
Q: What should I look for — and watch out for — on a sulfate-free hand soap label?
A: Start with the first five ingredients. That's where the formula lives — and where most brands hide what they don't want you to find.
Look for:
A cleansing agent with an independently verified safety profile
Third-party performance data on the label or brand website
Complete ingredient transparency — every ingredient, no exceptions
A brand that answers clearly: what replaced the sulfates and why is it better?
Watch out for:
SLS replacements with similar irritation profiles: cocamidopropyl betaine, sodium cocoyl isethionate, sodium lauroyl sarcosinate
SLES anywhere — EPA confirms 1,4-dioxane contamination risk from the ethoxylation process
Unregulated front-label claims — "natural," "gentle," "clean," "plant-based" carry no FDA definition
Moisturizing ingredients added to offset barrier damage the formula still causes — symptom treatment, not mechanism replacement
The standard we held ourselves to before putting a single claim on NOWATA's label:
Every ingredient published
Every performance claim third-party verified
Every formulation decision explainable to a parent reading it at 11pm
If we couldn't meet that standard — the formula wasn't ready
Q: Why did two doctors create a sulfate-free hand soap — and what makes NOWATA genuinely different?
A: Because we ran out of formulas we trusted for our own children — and had the training to understand exactly why.
What the research confirmed that no brand had acted on:
CDC validated physical contaminant removal for decades — no soap brand built around it
"Gentle vs. effective" was never a scientific conclusion — it was a design limitation accepted as permanent
The sink requirement was limiting hand hygiene compliance more than any formula ingredient
What most sulfate-free formulas solve:
SLS off the ingredient list — nothing else
What NOWATA solves that no other formula addresses together:
Mechanism — physical removal through plant-based clumping technology; no surfactant stripping, no barrier cost
Access — no sink required; the moments hand hygiene matters most rarely happen near running water
Verification — independent Swiss lab testing because we were building this for our own kids first — not because any law required it
What that produces:
100% plant-based
Zero sulfates, parabens, alcohol
99.9% germ removal — third-party verified
80–100 uses per tube
No rinse, no surfactant damage, no sink
We didn't start with a product concept. We started with a problem we couldn't solve any other way. The formula that didn't exist for our children is the formula we built. Everything that followed came from that single decision — to stop accepting the industry's answer and build a better one.
