Application:
PVP (polyvinylpyrrolidone) is a chemical ingredient that, depending on the formulatory requirement, can act as a binder, viscosity controller, emulsion stabilizer, or film former. Its benefits include water and wear resistance, pigment dispersion, a non-greasy feel, and improved stick integrity. PVP is commonly found in waterproof sunscreens, mascaras, and lipsticks in order to improve their wear.
