They are also useful auxiliary materials in skin-care product, hair-dying reagent, shampoo, lipstick, deodorant, sunscreen and dentifrice. ■ Pharmaceutical industry: :PVP-K30( Pharmaceutical grade) is a kind of new excellent pharmaceutical recipient. It is mainly used as binder for tablet and granule, dissolving assistant for injection, flow assistant for capsule, dispersant for liquid medicine and pigment,stabilizer for enzyme and heat-sensitive drug, coprecipitant for poorly soluble drugs, lubricator and antitoxic assistant for eye drug. PVP has been used as recipient in more than one hundred drugs. ■ Other applications: Suspensant, dispersant and emulsifier Disinfector Paint and coating Printing ink Textile and dyestuff Building material Paper making TV kinescope Polymer ultra-filtration membrane, micro-filtration membrane Glass fiber Packing: 25KG, 50KG double-layer PE bag lined fiber can Storage: Sealed, kept in dry and dark place at normal temp.
