Polyvinylpyrrolidone (PVP) is a fine chemical downstream of acetylene. PVP is a moisturizing and detoxifying agent for cosmetics, which can effectively remove the irritation of cosmetics on the skin and help to soften and lubricate the skin. For hair cosmetics, PVP and its copolymers have the functions of styling, hair care, increasing the luster and smoothness of hair, and are indispensable raw materials for styling hair lotion, mousse and hair spray. As a bonding excipient, thickener, solubilizer, dispersant, stabilizer, film forming agent and disintegrator in medicine, it is considered to be one of the most important medicinal synthetic new excipients in the world. Povidone iodine (PVP-I) with PVP as the main raw material is a new type of non-toxic, non-irritating and highly efficient germicidal disinfectant, and can also be directly used as medicine. Cross-linked PVP(PVPP) can be used as a clarifying agent and stabilizer for beer, wine and juice.
