Frequently asked questions

Is polyethylene terephthalate safe during pregnancy?
Authoritative cosmetic safety review by the Cosmetic Ingredient Review (CIR) concluded modified terephthalate polymers including polyethylene terephthalate (PET) are safe as used in cosmetics; ECHA lists PET as a polymer substance but there is no harmonised CLP reproductive classification (no H360/H361) for this substance. No peer‑reviewed human teratogenic or developmental-reproductive effects for PET as used in cosmetics were identified; systemic exposure from topical application of a high-molecular-weight polymer like PET is negligible. (CIR 2016; ECHA substance information; PubMed literature searches).
Is polyethylene terephthalate safe while breastfeeding?
Same rationale as pregnancy: no harmonised reproductive or lactation hazard classification, CIR safety assessment found PET appropriate for cosmetic use, and the polymer’s high molecular weight and inert polymeric form make systemic uptake from topical use unlikely, so transfer via breast milk is not supported by evidence.
Is polyethylene terephthalate safe for baby skin?
PET is a high‑molecular‑weight polymer (commonly used as solid film/glitter/particles) with negligible dermal absorption in its polymeric form; CIR assessed terephthalate polymers for cosmetic use including leave‑on products and did not identify developmental hazards. Note: concerns about PET are mainly environmental (microplastics) and ingestion of microplastic particles has been reported in infants in fecal studies, but that is different exposure route than topical cosmetic use on infant skin.
