Triacontanyl PVP
Triacontanyl PVP
A wax-like polymer for long-wear products. It thickens the oils and helps the layer resist water and rubbing off.
What it does
A polymer with a long fatty chain, which makes it waxy and able to mix with oils. It thickens the oils in a product and helps the layer on skin resist water and rubbing off, so it’s common in long-wear and water-resistant products.
The evidence, graded
expert consensusUS safety reviewers (2024) assessed 30 vinylpyrrolidone (VP) polymers, most of which products use to form a film. They judged 27 of them safe as used, PVP, triacontanyl PVP and hydrolyzed wheat protein/PVP crosspolymer among them; for the other 3, all urethanes, the data were too thin to judge.Johnson 2024 · International Journal of Toxicology ↗
