More About Non Toxic Toilet Paper

Does toilet paper have PFAS in it?

Yes, most conventional toilet paper has trace amounts of PFAS, generally in the parts-per-billion range. A 2023 study at the University of Florida tested toilet paper rolls from North America, South and Central America, Africa, and Western Europe, and found 6:2 fluorotelomer phosphate diester (6:2 diPAP) as the most prevalent PFAS in nearly every sample. The leading explanation is that PFAS-containing additives are used during pulp processing and end up as residual contamination in the finished paper, rather than being deliberately added to the toilet paper itself.

In North America, the study estimated that toilet paper contributes around 4% of the 6:2 diPAP entering wastewater, with cosmetics, textiles, and food packaging contributing more. And recycled-content toilet paper did test higher for PFAS in the same study, which makes sense because recycled fiber feedstock can carry PFAS contamination from other paper products in the recycling stream.

Do the PFAS in toilet paper affect health?

The honest answer is that we don't fully know yet, and the realistic picture has both real concerns and real uncertainty. There are three exposure pathways worth thinking about:

• First, direct skin contact. Dermal absorption of PFAS is an active research area, and current evidence suggests it's a real but small contributor to total body burden compared to ingestion routes, especially relevant for the more sensitive skin of the vulvar area where the contact is daily.

• Second, lint and dust generated by toilet paper, which can be inhaled or settle into household dust and reach the gut via hand-to-mouth contact.

• Third, the wastewater route, where PFAS flushed down the toilet enters wastewater systems, contributes to environmental PFAS load, and can show up in drinking water if it isn't fully removed by treatment plants. This is more of a community-level exposure than a personal one (the dilution from any one household's contribution is enormous), but it adds to the broader environmental PFAS picture that drinking water filtration is meant to address.

On 6:2 diPAP specifically, one cross-sectional study of 902 men in China found inverse associations between plasma 6:2 diPAP and androgen levels, suggesting possible effects on Leydig cell function and testosterone production. That finding is consistent with higher-dose animal studies showing reproductive toxicity, but it's one epidemiological study with active methodological discussion in the literature, so it's worth treating as emerging evidence rather than established effect.

Why do some natural and chemical free TP brands still have PFAS in them?

Likely contamination somewhere along the supply chain. PFAS are persistent and pervasive enough that they show up in products even when they're not deliberately added, including products from brands actively trying to keep them out. This affects many industries, not just toilet paper. The brands with the most credible PFAS-free claim are the ones that test their finished product and publish the results, since "we don't add it" doesn't rule out trace contamination from upstream materials.

Does toilet paper have formaldehyde in it?

Probably not in any meaningful sense anymore, despite what you've likely read online. The "formaldehyde in toilet paper" claim is widespread but rests on outdated paper chemistry. Modern tissue products use polyamideamine-epichlorohydrin (PAE) wet-strength resins, which replaced the older formaldehyde-based resins (urea-formaldehyde and melamine-formaldehyde) in tissue manufacturing decades ago because PAE works at neutral pH and formaldehyde is regulated by OSHA as a workplace hazard. The peer-reviewed paper-chemistry literature is consistent on this point.

That doesn't mean wet-strength chemistry is a non-issue. PAE can leave residual byproducts in the finished paper, including trace adsorbable organic halogens (AOX) like residual epichlorohydrin and 1,3-dichloropropanol, both of which have their own toxicology questions (epichlorohydrin is a known animal carcinogen and a probable human carcinogen per IARC, and 1,3-DCP is genotoxic in vitro). Modern PAE manufacturing has substantially reduced these residuals, but they're not zero.

So "formaldehyde-free toilet paper" is technically true of nearly all current tissue products, regardless of whether the brand markets it that way, but "free of wet-strength resin chemistry entirely" is a different question and not really achievable outside of unbleached, untreated paper like Plant Paper.

Can toilet paper cause chronic vulvar irritation?

Potentially, yes. If you have an allergy to formaldehyde and you’re using toilet paper that contains formaldehyde, which is very rare now, it’s possible. A 2010 case report described one patient with a confirmed formaldehyde allergy whose chronic vulvar irritation resolved after switching toilet paper. That's a single case report of a person with a confirmed allergy, not population-level evidence that toilet paper causes vulvar irritation. Vulvar irritation has many more common causes (yeast and bacterial infections, hormonal changes, fragrance and preservative allergies in personal care products), and toilet paper is far from the most likely source for most people.
