BUTYLATED PVP.

Valuable CAS 26160-96-3 / BINDING, FILM FORMING, HAIR FIXING

A lipophilic polymer that creates protective, water-resistant films on skin surfaces while dramatically boosting sunscreen performance. This specialized film-former enhances UV filter distribution and significantly improves product longevity and resistance to water exposure. Its unique molecular structure makes it particularly valuable in high-performance skincare formulations requiring durability.

Summary

Film forming UV filter booster Water resistance enhancer Product longevity improver

Science

Mechanism of Action

Forms a thin, flexible hydrophobic barrier on skin by creating polymer chains that adhere to the surface. Enhances UV protection by dispersing sunscreen filters more uniformly across the skin and scattering incident UV radiation, increasing the probability of UV absorption by active ingredients.
