    Polyvinylpyrrolidone is a ketone organic compound, which can be used as a clarifier; Stabilizer; Thickening agent; Tablet filler; Dispersant. PVP with molecular weight of 360 thousand is often used as clarifier for beer, vinegar, wine and so on. It has antiseptic properties, and is widely used in hair styling and combing products as film former, softener and stabilizer of skin care emulsion and cream, base material of eye and facial beauty cosmetics and lipstick, dispersant in hair dye and foam stabilizer of shampoo. PVP can detoxify and reduce the irritation of other preparations to skin and eyes. It is also used in toothpaste as a detergent, gelling agent and antidote. The main disadvantage of polyvinylpyrrolidone PVP is that it is sensitive to moisture, but the influence of moisture and humidity can be alleviated by using its vinyl acetate copolymer. In addition, PVP is widely used in medicine, beverage and textile industries.

    PVP for short is a polymer PVPP(polyvinylpolypyrrolidone, which can be divided into soluble PVP and insoluble PVPP because of its different polymerization degree. Soluble PVP has a relative molecular weight of 8000 ~ 10000, which can be used as a precipitant, and it can be precipitated by interaction with polyphenols. By this method, it is easy to have residual PVP in wine. Because PVP has the function of accumulating in human body, the World Health Organization does not recommend the use of this substance. In recent years, the use of soluble PVP is rare. Insoluble PVPP system began to be used in beer industry in the early 1960s, and its relative molecular mass is more than 700,000. It is a polymer insoluble substance formed by further crosslinking polymerization of PVP, which can be used as an adsorbent for polyphenols with good results.
    In the early 1950s, the older hair styling agent based on shellac and oil was quickly replaced by polyvinylpyrrolidone PVP spray, which is still widely used. It can form a re-wettable, transparent film on hair, with luster and good lubricity. PVP has good compatibility with all kinds of propellants, and it has anticorrosion performance. It is widely used in hair styling and combing products as film forming agent, emollient and stabilizer of skin care lotion and cream, base material of eye and face beauty cosmetics and lipstick, dispersant in hair dye and foam stabilizer of shampoo. PVP can detoxify and reduce the irritation of other preparations to skin and eyes. It is also used in toothpaste as a detergent, gelling agent and antidote. The main disadvantage of polyvinylpyrrolidone PVP is that it is sensitive to moisture, but the influence of moisture and humidity can be alleviated by using its vinyl acetate copolymer.
