VP/Eicosene Copolymer
An oil-loving film former that helps sunscreen or makeup resist sweat and water — also spreads pigments and filters evenly.
What it does
VP/eicosene copolymer is an oil-soluble film former. It is a wear-and-water-resistance ingredient rather than a skin active.
The evidence, graded
expert consensusUS safety reviewers (2024) assessed 30 vinylpyrrolidone polymers, most of which products use to form a film. They judged 27 safe as used, VP/eicosene copolymer among them; the other three had too little data. They noted two people who reacted to it in patch tests: one with atopic skin, and one whose face broke out in eczema after a sunscreen containing it.Johnson 2024 · International Journal of Toxicology ↗
