Polyvinylpyrrolidone (PVP K90)

O PVP K90 (Polyvinylpyrrolidone) It is a water-soluble, high molecular weight synthetic polymer, primarily used as a high-viscosity film-forming agent. Also known as povidone or PVP, it exhibits film-forming and wetting properties.

In aqueous solution, it exhibits Newtonian viscosity behavior. In dry form, it is a slightly flocculent powder with the ability to absorb moisture from the air. It is especially used in high-performance hair fixatives and other cosmetic formulations.

Benefits

• It shapes films and movies.
