A peer-reviewed review published in 2025 found that conventional bedding, towels, and infant clothing carry a documented load of PFAS, phthalates, carcinogenic azo dyes, and microfibers. Bedding and skin-contact textiles were identified as a primary exposure pathway — particularly for infants, pregnant women, and young children who spend extended time in direct contact with these surfaces.

What it actually means
The review covers four chemical categories with distinct mechanisms. PFAS are applied as water-repellent and "easy care" finishes; they migrate off fabric through skin contact and laundering. Phthalates are used as plasticizers in synthetic fiber coatings and printed graphics — the study specifically flags their detection in infant clothing elastics and PVC print applications. Azo dyes cleave under biological conditions to release aromatic amines, several classified as probable or known carcinogens. Microfibers released during washing carry adsorbed chemicals into household dust.
The authors don't conflate detection with confirmed harm at typical exposures. What the evidence establishes is that exposure through dermal and inhalation routes is ongoing, and conventional finishing processes reliably introduce these compounds into finished goods.
OEKO-TEX STANDARD 100 and GOTS are the certifications with credible third-party restriction lists.
In the home
Sheets marketed as "wrinkle-resistant," "easy care," or "no-iron" typically rely on formaldehyde-based resins and PFAS-containing finishes. Eight hours of skin contact per night — a third of every day — with these surfaces is a sustained exposure window. Azo dyes in colored bedding add a secondary layer through fabric off-gassing, especially when textiles are new.
Infant clothing received specific attention in the Rovira review for phthalate content — detected in waistbands, printed graphics, and soft PVC applications. Because infants mouth clothing and spend extended time with fabric against skin, the effective exposure per body weight is meaningfully higher than for adults.
What to do
GOTS certified and OEKO-TEX STANDARD 100 both restrict PFAS, azo dyes, phthalates, and formaldehyde with independent testing requirements. They are the practical filter for bedding, towels, and children's clothing. If you're shopping right now, the product directory is filtered against the criteria this study calls out.
