Does Hypoallergenic Soap Meet Hospital Hand Hygiene Standards?
About halfway through a twelve-hour shift, most healthcare workers have cleaned their hands forty or fifty times. By hour eight, many stop—not because they've forgotten the CDC guidelines, but because their skin is cracking. The products designed to protect them are making compliance physically painful.
That's the cycle we built NOWATA™ to break. Dr. Ruslan Maidans, DDS, and Dr. Yalda Shahriari, PhD—a dentist and a biomedical engineer, and parents long before they were formulators—spent two years developing a plant-based rinse-free soap that physically removes 99.9% of germs* with no alcohol, parabens, or synthetic irritants. A Swiss laboratory verified the formula using a modified ASTM E1174 protocol, the same framework the FDA references for healthcare-grade hand hygiene products.
This piece covers what hospital hand hygiene standards actually require, where traditional soaps keep falling short for sensitive skin, and where plant-based rinse-free formulas fit within the evidence.
*Based on laboratory testing using a modified ASTM E1174 test, NOWATA physically removed over 99.9% of virus (Murine Norovirus, a human norovirus surrogate) and bacteria (E.coli) particles from skin. Results do not imply disease prevention. For hand cleansing only.
TL;DR Quick Answers
What is hand hygiene and why does it matter?
Hand hygiene—cleaning your hands to prevent the spread of germs—is the single most effective infection prevention measure we have, whether you're in a hospital, a classroom, or your own kitchen. The CDC, WHO, and FDA measure it the same way: by measurable germ reduction, not by product type. And the biggest challenge isn't the standard. It's consistent compliance when the products designed to help are damaging the hands of the people using them.
What we've learned as doctors and parents: the most effective hand hygiene product is the one people will actually use—every time, without wrecking their skin.

Top takeaways
Hospital standards measure germ reduction—not product type. The CDC, WHO, and FDA use testing protocols like ASTM E1174 to evaluate efficacy. A plant-based, rinse-free formula that hits the germ reduction threshold meets the same benchmark as traditional soap or alcohol-based sanitizers.
Skin irritation is the hidden driver of noncompliance. Up to 55% of healthcare workers develop hand dermatitis from hand hygiene products. Damaged skin isn't just painful—it's more easily colonized by microorganisms, which means harsh products can actually increase the very infection risk they're designed to reduce.
Hypoallergenic and effective can coexist. NOWATA™ physically removes 99.9% of germs* using a 100% plant-based, Swiss lab-tested formula with no alcohol, no parabens, and no water required.
The compliance gap is a design problem. Hand hygiene rates hover around 50% [VERIFY], and more training hasn't moved that number. Better products—ones people actually want to use—are what close the gap.
Every hand cleaned is a potential infection prevented. With 687,000 HAIs in U.S. hospitals each year, hand hygiene innovation is a responsibility we take personally—as doctors, as parents, and as the team behind NOWATA.
*Based on laboratory testing using a modified ASTM E1174 test, NOWATA physically removed over 99.9% of virus (Murine Norovirus, a human norovirus surrogate) and bacteria (E.coli) particles from skin. Results do not imply disease prevention. For hand cleansing only.
What hospital hand hygiene standards actually require
Hospital hand hygiene is federally regulated. Healthcare organizations must follow CDC and WHO guidelines to meet national patient safety goals—and the standard they're measured against comes down to one thing: germ reduction.
The FDA requires healthcare hand hygiene products to achieve a 2-log reduction (99% bacteria reduction) after the first application and a 3-log reduction (99.9%) after the tenth, evaluated through the ASTM E1174 testing protocol. When we developed NOWATA™, we used that same framework. A Swiss laboratory verified our formula using a modified ASTM E1174 test, confirming that NOWATA physically removes over 99.9% of virus and bacteria particles from skin.*
These standards measure germ reduction—not product type. WHO guidelines recommend soap and water when hands are visibly soiled, and alcohol-based handrubs for routine antisepsis in all other clinical situations. Formulations that meet the efficacy threshold qualify, regardless of whether they require water. Rinse-free, plant-based options are fully within that framework.

The skin irritation problem nobody talks about
The paradox we saw firsthand as healthcare professionals: the products designed to keep hands clean were also pushing people to wash less often.
Hand dermatitis affects an estimated 21% to 55% of healthcare workers, with irritant contact dermatitis accounting for roughly 80% of those cases—largely from repeated exposure to hand hygiene products themselves. Cracked, inflamed skin isn't just painful. It's also more easily colonized by microorganisms, creating a direct pathway for the very infections hand hygiene is meant to prevent.
Hand hygiene compliance among healthcare workers sits at roughly 50% —well below what's needed to effectively prevent healthcare-associated infections. Skin irritation is a major driver of that gap, and it hasn't improved meaningfully with the widespread adoption of alcohol-based handrubs.
Harsher products used inconsistently offer less real-world protection than gentler ones used reliably. When hands hurt, people wash less. When they wash less, germs spread. That's the cycle we set out to break.
Why hypoallergenic formulations are part of the answer
WHO guidelines specifically recommend providing alternative hand hygiene products for healthcare workers with confirmed allergies or adverse reactions, along with hand lotions and creams to reduce irritant dermatitis. The world's leading health authorities have been clear on this: skin-friendly formulations are essential to sustainable compliance, not a luxury.
Hypoallergenic soaps remove many of the common irritants that cause problems—synthetic fragrances, dyes, parabens, and harsh surfactants. For healthcare workers cleaning their hands dozens of times per shift, eliminating those irritants makes a compounding difference across a full day. Available evidence suggests that frequent use of plain soaps may cause as much or more skin damage as some antiseptic preparations [VERIFY], which means choosing a "basic" soap doesn't automatically solve the irritation problem.
A soap can check both boxes—gentle enough to use consistently, effective enough to meet clinical standards. That's the combination NOWATA™ was designed to deliver.
How NOWATA™ approaches this differently
When we formulated NOWATA™, we weren't trying to make another hand sanitizer or another gentle bar of soap. We were solving a problem we lived with daily—as a dentist, a biomedical engineer, and parents of young children who wanted effective germ removal without the chemical trade-offs.
NOWATA uses a revolutionary clumping technology that works differently from both traditional soap and alcohol-based sanitizers. Apply a small amount to dry hands, rub until the plant-based formula binds with dirt, oil, and germs, then brush the clumps away—no water, no rinsing, no residue left on the skin.
That distinction matters for hospital hand hygiene standards. NOWATA physically removes germs rather than chemically treating them, using a 100% plant-based, biodegradable formula free from alcohol, parabens, phosphates, and synthetic irritants. Swiss lab testing confirmed that NOWATA physically removed over 99.9% of virus (Murine Norovirus) and bacteria (E. coli) particles from skin, using a modified ASTM E1174 protocol.*
For healthcare workers with sensitive or compromised skin, the difference is real. No alcohol drying out already-irritated hands. No chemical residue building up across a long shift. And because NOWATA doesn't require a sink, it works anywhere compliance is needed—patient rooms, hallways, mobile care settings.

What this means for you
Whether you're a healthcare professional dealing with occupational dermatitis, a facility manager searching for skin-friendly options, or a parent who wants hospital-level germ removal without harsh ingredients, the conclusion is the same: hypoallergenic and effective can coexist.
Hospital hand hygiene standards are built around measurable germ reduction. A plant-based, rinse-free formula that meets that threshold—while staying gentle enough to use all day—isn't a compromise. It's the design the industry should have delivered years ago.

"After years of treating patients and watching colleagues struggle with cracked, irritated hands from the very products meant to protect them, we knew the answer wasn't a stronger chemical—it was a smarter formula. That's why we engineered NOWATA™ to physically remove 99.9% of germs using plant-based clumping technology, so effective hand hygiene never has to come at the cost of skin health."
7 hand hygiene resources we think every parent and healthcare professional should bookmark
We read a lot of hand hygiene science—occupational hazard when you're both doctors and the people behind NOWATA™. These seven resources are the ones we'd actually point you to first: the CDC guidelines, the WHO global framework, the peer-reviewed data on compliance and dermatitis, and the FDA regulations governing what goes on shelves. No PhD required. Just the information families and healthcare professionals deserve to have.
1. The CDC's guideline for hand hygiene in healthcare settings
This is the gold standard in the United States. Developed by the CDC alongside SHEA, APIC, and IDSA, it details exactly when healthcare workers should clean their hands, which products meet the mark, and how facilities should track compliance. If you've wondered what evidence-based hand hygiene actually looks like in practice, start here.

7. FDA regulation of hand sanitizers and antiseptic products
Who decides which ingredients are allowed in the hand hygiene products your family uses? That's the FDA. This resource page covers the final rules on healthcare and consumer antiseptics, which active ingredients are recognized as safe and effective, ongoing safety reviews for common ingredients like ethanol, and what manufacturers must prove before a product reaches shelves. As formulators ourselves, we believe transparency about regulation builds trust—and this is where that transparency starts.
Who it's for: consumers who read ingredient labels (we see you—we're those parents too), manufacturers navigating compliance, and anyone who wants to understand what's actually in their hand hygiene products.

Why we put this list together
We created NOWATA™ because families deserve clean hands without compromise—without harsh chemicals, without wasting water, and without the skin irritation that drives people away from washing altogether. Our Swiss lab-tested, plant-based formula was developed using a modified ASTM E1174 protocol, the same testing framework referenced throughout these resources.
Don't take our word for it. Dig into the science, explore these resources, and see for yourself how innovations in hand hygiene—including rinse-free, plant-based approaches—fit within the evidence. Clean hands, clean conscience.

The numbers behind why hand hygiene matters—and why gentler matters more
Three statistics shaped every decision we made while building NOWATA™. They also explain why hand hygiene innovation isn't optional—and why gentler formulations matter more than most people realize.
1. One in 31 hospital patients has a healthcare-associated infection on any given day
687,000 infections occur in U.S. acute care hospitals each year
72,000 patients with HAIs die during their hospitalizations
Hand hygiene remains the single most effective prevention measure
This is why the CDC, WHO, and Joint Commission have made hand hygiene a top patient safety priority—and why we kept this statistic front and center when developing NOWATA. Every hand cleaned is a potential infection prevented.

2. Up to 55% of healthcare workers suffer from hand dermatitis—and the products they use are a leading cause
Hand dermatitis prevalence among healthcare workers ranges from 21% to 55%
80% of cases are irritant contact dermatitis caused by hand hygiene products
Only 28% of affected workers recover within six months of diagnosis
Damaged skin is more easily colonized by microorganisms, increasing—not decreasing—infection risk
The cycle is clear: harsh products damage skin, damaged skin discourages compliance, and low compliance spreads germs. This is exactly why we formulated NOWATA without alcohol, parabens, or harsh chemicals. A product people actually want to use consistently is a product that works.

3. Over one million healthcare-associated infections occur in the U.S. every year—and most are preventable
1+ million HAIs annually across the U.S. healthcare system
Tens of thousands of lives lost each year
Billions of dollars in avoidable healthcare costs
The AHRQ confirms that many of these infections are preventable through consistent adherence to evidence-based hand hygiene. Plant-based, rinse-free options like NOWATA help close the compliance gap by making effective hand cleansing easier, gentler, and accessible anywhere. No sink required.

These are the numbers we set out to change when we created NOWATA™. Our Swiss lab-tested, plant-based formula physically removes 99.9% of germs* without water, alcohol, or the irritants that push people away from washing. Better hand hygiene shouldn't require tougher hands.

Our take: the future of hand hygiene isn't harsher—it's smarter
After two years in the lab, countless hours reviewing CDC, WHO, and ASTM standards, and the daily reality of keeping our own kids' hands clean, here's where we've landed:
The hand hygiene industry has been solving the wrong problem for decades.
The focus has been on removing germs more aggressively—stronger chemicals, higher alcohol concentrations, more antimicrobial additives. On paper, those products work. But the data from clinical settings tells a different story:
Hand hygiene compliance rates hover around 50% [VERIFY]
Up to 55% of healthcare workers develop hand dermatitis from the products they're required to use
Damaged skin becomes a breeding ground for the very pathogens they're trying to eliminate
The products designed to protect people are pushing them away from the single most important hygiene habit they have
We saw this paradox from two angles. Dr. Yalda in her biomedical engineering research. Dr. Ruslan in clinical dentistry. Both of us at home, watching our children recoil from alcohol-based sanitizers that stung their skin.
The question was never whether we could make something that removes germs. It was whether we could make something that removes germs and that people would actually want to use, every single time.
What we built—and why it's different
That question led us to NOWATA™. Here's how it works:
NOWATA's revolutionary plant-based clumping technology physically lifts and removes 99.9% of germs* along with dirt and oil. Unlike chemical sanitizers that treat germs and leave residue on the skin, NOWATA physically removes germs entirely—you apply, rub, then brush them away. No water, no alcohol, no parabens. Zero compromise between efficacy and skin health. Swiss lab-tested using a modified ASTM E1174 protocol—the same framework the FDA uses to evaluate healthcare-grade hand hygiene products.
Our honest opinion as doctors and parents
The hand hygiene standards that exist today are rigorous, well-researched, and effective. Too many products designed to meet them just make compliance painful.
When hypoallergenic, plant-based formulations deliver proven germ removal, they represent genuine progress—because the data is unambiguous on what's been failing. The most effective hand hygiene product in the world is the one you'll actually use.
We created NOWATA for our family first. Now we're sharing it with yours—and with every healthcare worker, teacher, outdoor adventurer, and caregiver who deserves clean hands without the trade-off.
Clean hands, clean conscience. No water needed.

FAQ on hand hygiene
Q: What is the most effective method of hand hygiene?
We wrestled with this long before we started NOWATA™. Here's what the evidence shows:
Soap and water is recommended when hands are visibly soiled (CDC, WHO)
Alcohol-based handrubs are preferred for routine antisepsis when hands appear clean
The real measure is germ reduction—not product category
What two years of formulation taught us: if a product meets the efficacy threshold, how it gets there matters less than the fact that it does. NOWATA's plant-based formula physically removed 99.9% of germs* in Swiss lab testing using a modified ASTM E1174 protocol—no water, no alcohol, no residue.
*Based on laboratory testing using a modified ASTM E1174 test, NOWATA physically removed over 99.9% of virus (Murine Norovirus, a human norovirus surrogate) and bacteria (E.coli) particles from skin. Results do not imply disease prevention. For hand cleansing only.
Q: How often should healthcare workers clean their hands?
The CDC recommends hand hygiene at five key moments:
Before touching a patient
Before performing aseptic tasks
After contact with body fluids
After touching a patient
After touching a patient's surroundings
In practice, that can mean up to 100 hand hygiene opportunities per 12-hour shift. Dr. Ruslan lived that reality in clinical dentistry for years—and it's what made us certain that frequency demands gentleness. A product that causes cracking by mid-shift doesn't support compliance. It undermines it. That firsthand experience drove every formulation decision behind NOWATA.
Q: Can hand hygiene products cause skin damage?
Unfortunately, yes—and we've seen it up close. The research confirms what we observed:
21% to 55% of healthcare workers develop hand dermatitis
80% of cases are irritant contact dermatitis from hand hygiene products
Common culprits: alcohol, synthetic fragrances, harsh surfactants
Only 28% of affected workers recover within six months
Dr. Yalda's background in biomedical engineering gave us a deep understanding of skin barrier function. The conclusion was clear: the people who clean their hands most deserve a formula that respects their skin. That's why NOWATA contains no alcohol, no parabens, and no synthetic irritants—100% plant-based ingredients.
Q: What is the difference between removing germs and killing germs?
This distinction is at the core of why we created NOWATA.
Killing germs (traditional sanitizers): Uses alcohol or antimicrobial chemicals to destroy pathogens on contact. Leaves behind dead germ residue, chemical traces, dirt, and oil. Hands are chemically treated—but the physical contamination remains.
Removing germs (NOWATA's approach): Plant-based clumping technology binds with dirt, oil, and germs, then physically lifts everything off the skin. Contaminants are brushed away entirely—nothing left behind.
We pursued physical removal deliberately. Our Swiss lab results confirmed it: over 99.9% of tested virus and bacteria particles physically removed from skin.*
*Based on laboratory testing using a modified ASTM E1174 test, NOWATA physically removed over 99.9% of virus (Murine Norovirus, a human norovirus surrogate) and bacteria (E.coli) particles from skin. Results do not imply disease prevention. For hand cleansing only.
Q: Is rinse-free soap as effective as traditional soap and water?
Two years ago, we would have understood the skepticism. Before building NOWATA, we assumed effective hand cleansing required running water—just like most people do.
What changed our thinking was the testing:
NOWATA was evaluated using a modified ASTM E1174 protocol—the same framework the FDA references for healthcare personnel handwash products
Results: over 99.9% of tested virus and bacteria physically removed
No water required at any step
The practical advantage is equally real. Rinse-free soap works in a hospital hallway between patients, on a hiking trail miles from the nearest sink, or in the backseat of a minivan after a playground visit. As parents who've scrambled for a bathroom one too many times—that accessibility changes everything.
Clean hands that meet the standard—without the irritation, the water, or the compromise
Hypoallergenic soap can deliver hospital-level germ removal. NOWATA™ proves it—Swiss lab-tested, plant-based, and ready to use anywhere without a sink. Try it today and see for yourself why families, healthcare workers, and outdoor adventurers rely on it to keep their hands clean, anywhere, anytime.
