About

A crosslinked form of polyvinyl alcohol (PVA) — a film-forming polymer used in peel-off masks and primers. Safe but under microplastic scrutiny.

Polyvinylalcohol crosspolymer (CAS 93409-71-3 family) is a crosslinked form of polyvinyl alcohol (PVA), often obtained by reaction with aldehydes like glyoxal. It functions as a film former, thickener, and viscosity modifier in cosmetics, prominently in peel-off masks and long-wear primers. PVA itself has food-contact safety precedent and is generally regarded as low-toxicity. The crosslinked form shares this basic safety profile but is under increasing scrutiny within the EU microplastics restriction framework, which is progressively restricting insoluble synthetic polymers in cosmetics. No GHS hazards for finished polymer at cosmetic use levels.
