Uses and synthesis of Polyvinylpyrrolidone powder

Polyvinylpyrrolidone powder, referred to as PVP, is a polymer of vinylpyrrolidone and a crosslinked homopolymer of pure vinylpyrrolidone. Polyvinylpyrrolidone a flowing white or nearly white powder with definite hygroscopicity. It smells slightly. Medical insoluble in water and ethanol, ether and other commonly used solvents, so the range of molecular fish can not be measured; Polyvinylpyrrolidone is widely used as thickener, emulsifier, lubricant and clarifying agent, and also as the complex of PVP-I disinfection agent

Applications/Functions of Polyvinylpyrrolidone powder

• Polyvinylpyrrolidone powder is used as a colloidal stabilizer and clarifying agent for the clarification of beer in appropriate amounts as required for production.
• Clarifying agent; Stabilizer; Thickening agent; Tablet filler; Dispersant. Molecular weight of 360,000 polymer PVP is commonly used as beer, vinegar, wine and other clarifying agents.
• Polyvinylpyrrolidone is widely used as thickener, emulsifier, lubricant and clarifying agent, and also as the complex of PVP-I disinfection agent
• In daily cosmetics, PVP and copolymers have good dispersibility and film forming properties, which can be used as styling liquid, hair spray and mousse setting agent, hair conditioner sunshade, shampoo foam stabilizer, wave setting agent and hair dye dispersant and affinity agent.
• Polyvinylpyrrolidone is a ketone organic compound that can be used as a clarifier, stabilizer, thickener, tablet filler, and dispersant. The high molecular weight PVP with a molecular weight of 360,000 is often used as a clarifier for beer, vinegar, wine, etc.

Physicochemical Property of Polyvinylpyrrolidone powder

White powder, slightly smelly. It is hygroscopic. Soluble in water, ethanol, ether and other organic solvents. It has strong complex adsorption capacity for many substances.

Product method of Polyvinylpyrrolidone powder

It is obtained by cross-linking homopolymerization of a 30% to 60% aqueous solution of purified 1-vinyl-2-pyrrolidone in the presence of ammonia or amines, using hydrogen peroxide as a catalyst at 50°C, and then purifying it.
