Film Formers (Cosmetic Ingredients)

Film formers are ingredients used to create a thin, uniform film on the surface of the skin or hair. Depending on their film-forming capabilities, they serve a wide range of purposes—from providing basic functionality to enhancing specific effects or improving long-lasting performance. These ingredients play an important role in improving texture, durability, and the overall sensory experience of cosmetic products.

BISHOKUBAI™ CV Series (Polyvinylpyrrolidone : PVP)

Item Number	BISHOKUBAI™ CV-2733	BISHOKUBAI™ CV-8387	BISHOKUBAI™ CV-8896
Features	PVP is a nonionic, water-soluble polymer produced by polymerizing N-vinylpyrrolidone. It exhibits excellent hygroscopicity, adhesion, and dispersibility. Our PVP is characterized by a low residual monomer content, which minimizes yellowing and odor changes over time. It dissolves well in water and forms a viscous solution. Leveraging its film-forming ability and strong adhesion to hair, it is used in hair care products.
