Polyvinylalcohol Crosspolymer

Polyvinylalcohol Crosspolymer is an inert, high–molecular weight film-forming/texture agent typically used at low percentages to stabilize gels or create a smooth, blurring finish. It is not a biologically active ingredient and is generally negative in standard irritation testing, with reactions most often related to mechanical film tightness or contamination rather than true chemical irritancy. For severely compromised barriers, that occlusive/film effect can occasionally feel stinging or tight, so it is scored as exceptionally gentle rather than completely inert. Safety Notes: Polyvinylalcohol Crosspolymer is most commonly used as a film-forming/structuring polymer in peel-off masks, primers, and long-wear/mattifying leave-on products, where it can be present at very low levels (~0.05–0.3%) as a secondary texture aid. In dedicated peel-off mask and film-forming products available OTC, it can be a primary structurant and rise into the several-percent range, with the strongest consumer products observed around ~8–10% to build a cohesive peelable film. Rinse-off formats (cleansers) typically sit at the low end due to limited need for durable films, while leave-on/peel-off products drive the high end.
