pvp is polyvinylpyrrolidone. Polyvinylpyrrolidone (PVP) is a kind of non-ionic polymer compound. PVP is made from vinyl pyrrolidone (NVP) by bulk polymerization and solution polymerization. In the process of bulk polymerization, due to the viscosity of the reaction system, the polymer is not easy to diffuse, and the polymerization heat is not easy to remove, resulting in local overheating.

\u200bThere are two main routes for the production of PVP polymerization, the first is the solution polymerization of N-2-pyrrolidone (NVP) in organic solvents, followed by steam stripping. The second route is aqueous polymerization of NVP monomer with water-soluble cation, anionic or non-ionic monomer.
\u200bA crosslinked homopolymer of pure vinylpyrrolidone. Polyvinylpyrrolidone (PVP) has the ability to bind to a variety of substances, such as the various pigments that cause wine and other beverages to discolor. And because of its insolubility, it is easy to be removed after filtration.
Polyvinylpyrrolidone has good film forming and solubility, \u200c is miscible with water, \u200c can be dissolved in many alcohols, \u200c carboxylic acids, \u200c amines, \u200c halogenated hydrocarbons and other organic solvents. \u200cPVP is synthesized by polymerization of the monomer N-vinylpyrrolidone (\u200cNVP) \u200c in the presence of an initiator. \u200c this compound has very low toxicity and very high physiological inertia, \u200c has no irritation to skin and eyes, \u200c is widely used in cosmetics. \u200cPVP can form a non-occlusive film on the skin surface, \u200c plays the role of moisturizing and moisturizing, \u200c reduces greasy feeling, \u200c and has a good soft and smooth feeling. \u200c In addition, \u200cPVP can also accelerate the penetration of facial mask ingredients, \u200c extend the retention time of ingredients. \u200c In personal care products, \u200cPVP as a styling agent and film forming agent, \u200c has good film forming properties, \u200c can form a transparent film, \u200c has a good protective effect on hair, \u200c makes the hair fixed, \u200c lasting and keep bright, \u200c is not dusty. The excellent biocompatibility of \u200cPVP makes it not irritating to skin, \u200c mucosa and eyes, \u200c and is not carcinogenic in itself, \u200c has good food safety, \u200c is mainly used as a clarifier and stabilizer for beer, \u200c juice, \u200c wine and other foods in food processing. \u200c<\/p>\n
