What it is
VP/Hexadecene Copolymer is a copolymer of vinylpyrrolidone and hexadecene that forms a thin, cohesive film as the product dries on the skin. In sunscreens it helps hold the UV filters in an even layer and improves the uniformity and durability of the applied film, while in makeup it aids pigment dispersion and wear. It is an oil-compatible, non-tacky film former used as a formulation aid rather than a UV filter.
Safety & warnings
VP/Hexadecene Copolymer is generally well tolerated and is not a common sensitizer. As a lightweight film former it is not typically associated with significant comedogenicity at standard use levels.
Origin & sourcing
It is a synthetic polymer produced by copolymerizing vinylpyrrolidone with the hydrocarbon hexadecene.
Questions everyone asks
What does VP/Hexadecene Copolymer do in sunscreen?
It is a film former that helps keep the UV filters in an even, cohesive layer and improves how the dried film holds up on skin.
Is it a UV filter?
No. It is a formulation polymer that supports the film and texture; it does not absorb or reflect UV by itself.
