Protect Your Family from PFAS in Personal Care

PFAS — per- and polyfluoroalkyl substances — are among the most scrutinized chemical compounds in 2026, and for good reason. These "forever chemicals" don't break down in the environment or the human body. They accumulate. And they're increasingly found in a category that families apply directly to their skin every day: personal care products.

For parents already making intentional choices about food quality, water filtration, and household chemicals, PFAS in personal care represents a significant and often overlooked exposure vector. Here's what you need to know — and what to use instead. See also: What Your Skin Actually Absorbs

What Are PFAS and Why Do They Matter?

PFAS are a class of over 12,000 synthetic fluorinated compounds characterized by extremely strong carbon-fluorine bonds. That bond strength is why they're used in everything from non-stick cookware to waterproof clothing to stain-resistant cosmetics — and it's also why they don't break down.

Key PFAS characteristics:

• Environmental persistence: PFAS don't degrade in soil or water — they persist for decades, contaminating groundwater and food supplies
• Bioaccumulation: PFAS accumulate in human blood, liver, and fatty tissue over time — each exposure adds to the total burden
• Widespread detection: PFAS are now detected in the blood of virtually all Americans tested, including newborns — reflecting the pervasiveness of exposure sources
• Regulatory action: The EPA set the first enforceable drinking water limits for PFAS in 2024; the EU has moved to restrict PFAS broadly across cosmetics and personal care

Where PFAS Hide in Personal Care Products

PFAS appear in personal care for functional reasons — they create long-lasting, water-resistant, smooth-application properties that formulators prize. The categories most commonly containing PFAS include:

• Waterproof mascara and eyeliner: PFAS create the water-resistance that makes these products work as labeled
• Long-wear foundation and lipstick: PFAS film-formers increase staying power
• Water-resistant sunscreens: Some formulations use PFAS for water-resistance
• Dental floss: PFAS coatings are common — some major brands have now removed them following testing
• Moisturizers and serums: Certain perfluorocarbon compounds are used as skin-feel enhancers

In the US, PFAS disclosure is not required on cosmetic labels. The compound may not appear anywhere on the ingredient list — it can be present in raw materials used without being individually identified.

Health Risks from Personal Care PFAS Exposure

The health research on PFAS has accelerated rapidly. Current scientific understanding (I'd recommend verifying current research independently as this is a rapidly evolving field):

• Immune system effects: PFAS exposure has been associated with reduced immune response, including reduced vaccine effectiveness in children
• Hormonal disruption: Multiple PFAS compounds interfere with thyroid hormone function and sex hormone signaling
• Developmental effects: Prenatal PFAS exposure has been associated with birth weight effects and developmental outcomes
• Cancer associations: Specific PFAS (particularly PFOA and PFOS) have been classified as probable carcinogens
• Metabolic effects: PFAS exposure has been linked to insulin resistance and cholesterol dysregulation in some studies

Why Children Face Higher Risk from PFAS in Personal Care

Children are disproportionately affected by PFAS exposure for several reasons:

1. Developing systems: Children's immune, hormonal, and neurological systems are still developing — disruption at these stages has potentially larger and more lasting effects than adult exposure
2. Higher absorption-to-body-weight ratio: Children absorb a higher dose per body weight than adults from the same product application
3. Behavior: Children touch their faces and mouths more frequently, adding oral exposure to dermal exposure from personal care products
4. Cumulative exposure already high: Children born today already have measurable PFAS levels from maternal transfer, food, and environment — reducing personal care exposure meaningfully reduces total burden

For parents, personal care products applied to children — sunscreen, lotion, baby wash, first aid — deserve special scrutiny for PFAS content.

How to Identify PFAS in Your Personal Care Products

Without mandatory disclosure, PFAS identification requires active effort:

• Scan with Yuka: The Yuka app flags many known PFAS compounds in ingredient lists
• Look for fluorinated ingredient names: Ingredients containing "fluoro," "perfluoro," or "PTFE" in their name are PFAS indicators (though many PFAS don't disclose this clearly)
• Check EWG: The Environmental Working Group's Skin Deep database includes PFAS flagging for many products
• Choose products with zero fluorinated compounds: The only reliable protection is products formulated without any fluorinated compounds
• Require third-party certification: Products like Clayer that carry independent safety certifications (100/100 Yuka, certified non-toxic) provide higher-reliability PFAS-free assurance

The PFAS-Free Personal Care Standard for Families

Building a PFAS-free personal care routine requires replacing products in the highest-concern categories with certified alternatives:

Priority replacements:

• Conventional deodorant/antiperspirant → aluminum-free, PFAS-free natural deodorant
• Body lotion with fluorinated film-formers → mineral-based or simple plant oil formulations
• Children's products (sunscreen, lotion, wash) → certified non-toxic, fully disclosed ingredient lists
• Waterproof cosmetics → PFAS-free waterproof formulations (increasingly available)

Clayer: Zero-PFAS Family Personal Care

Clayer's entire product line contains zero fluorinated compounds — by design. French green clay doesn't require PFAS for any functional property. The ionic adsorption mechanism that makes clay effective in deodorant, recovery, and skin care is purely mineral-based.

For families building a genuinely clean personal care routine:

• Clayer Kids Care — certified non-toxic first aid for children; zero PFAS, zero heavy metals
• Natural Deodorant — no aluminum, no PFAS, 100/100 Yuka
• Sports Recovery Clay — zero synthetic compounds for active family members
• First-Aid Healing Clay — certified non-toxic wound and first aid support

Every Clayer product is certified heavy-metal-free and scores 100/100 on Yuka — providing the independent verification that PFAS-free claims require.

FAQ

Q: How do I know if my current personal care products contain PFAS?
A: Scan them on Yuka or check EWG Skin Deep. Look for any ingredient containing "fluoro," "perfluoro," or "PTFE." Note that some PFAS may not be individually disclosed — choosing products with zero fluorinated ingredients and third-party safety certification is the most reliable approach.

Q: Are baby and children's personal care products PFAS-free?
A: Not automatically. "Baby" and "gentle" labeling doesn't guarantee PFAS-free formulation. Test and verify individual products. Clayer Kids Care is certified non-toxic and free of fluorinated compounds.

Q: Does switching to natural personal care actually reduce PFAS exposure?
A: Yes — if you choose certified products without fluorinated compounds. Switching from conventional waterproof cosmetics, aluminum antiperspirant, and synthetic-compound personal care to verified clean alternatives meaningfully reduces daily dermal PFAS exposure.
