Application
1) Cosmetic
PVP-K series can be used as film-forming agents, viscosity-enhancement
agents, lubricate and adhesive. They are the key component of hair sprays,
monsse, gels and lotions and solution. They are also convenience assistant
in skin-care product, hair-dying reagent shampoo, eye makeup, lipsticks,
deodorants and dentifrices.
2) Pharmaceutical
PVP K 30 is a new and excellent pharmaceutical recipe. It is mainly used
as binder for tablet, dissolving assistant for injection, flow assistant for
capsular, dispersant for liquid medicine and pigment, stabilizer for enzymes
and heat sensitive drug, coprecipitant for poorly soluble drugs, lubricate
and antitoxical assistant for eye drug. PVP has been used as excipients in
more than hundred drugs.
