PVP

PVP is a synthetic water-soluble polymer created through the polymerization of N-vinylpyrrolidone, widely used in cosmetics since the 1950s. It forms transparent, flexible films on skin and hair, making it particularly valuable in hair styling products where it provides hold without stiffness or flaking. Formulators choose PVP for its excellent clarity in solution, compatibility with a broad range of ingredients, and ability to function across various pH levels, though it offers minimal humidity resistance compared to newer film-forming polymers.
