- Application field
Cosmetic: PVP-K series can be used as film-forming agent, viscosity-enhancing agent, lubricator and adhesive in hair sprays, mouses, hair-fixing gels and colution. They are also useful auxiliary materials in skin-care product, hair-dying reagent, shapoo, lipstick, deodorant, sunscreen and dentifrice.
Pharmaceutical: PVP-K30 (pharmaceutical grade) is a kind of new excellent pharmaceutical excipient. It is mainly used as binder for tablet and granule, dissovlving assistant for injection, flow assistant for capsule, dispersant for liquid medicine and pigment, stabilizer for enzyme and heat-sensitive drug, co-precipitant for poorly soluble drugs, lubricator and antitoxic assistant for eye drug. PVP has been used as excipient in more than one hundred drugs.
