Pharmaceutical: PVP-K series is one of new pharmaceutical excipients.

It is used as binder for tablet and granule, dissolving assistant and stabilizer for injection, flow assistant for capsule, dispersant for liquid medicine and stain, stabilizer for enzyme and heat sensitive drug, coprecipitator for poorly soluble drugs, lubricator and antitoxic assistant for eye drug and film-forming agent for coating. 2.

Cosmetics: PVP-K series can be used as dispersant, film-forming agent, viscosity-enhancement agent, lubricator and adhesive. They are used either in hair-care products, such as hair sprays, mousse, gelatin lotions&solution, shampoo and hair reagent, or in skin-care products, such as lipstick, sunscreen and modifier, deodorant and dentifrice. 3.

Water industry: PVP-K series are excellent pore-foaming agent in membrane technology and important material in hydrophily membrane industry. 4.

Other industries: PVP-K series can also be used in industries of suspension colloid agent ,dispersing agent and emulgator, plastic, resin, ink, tabletting assistant, pait, glass fiber, adhesive ,film, television picture tube, detergent, printing and dyeing, etc.
