Chemical properties A crosslinked homopolymer of pure vinyl pyrrolidone. A readily flowing white or nearly white powder with definite hygroscopicity. It smells slightly. Medicine is insoluble in water and ethanol, ether and other commonly used solvents, so the molecular range can not be determined. However, polyvinylpyrrolidone (PVP) has the ability to severely bond with a variety of substances (such as various pigments that cause wine and other beverages to discolor). And because of its insolubility, it is easy to be removed after filtration. Purpose clarifying agent; Pigment stabilizer; Colloidal stabilizer. It is mainly used for the clarification and quality stability of beer (reference dosage of 8 ~ 20g/100L, maintained for 24h and filtered out), and can also be combined with enzymes (proteases) and protein adsorbents. It is also used as a stabilizer for wine clarification and preventing discoloration (reference dosage 24 ~ 72g/100L). Purpose 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. Uses As a gas chromatography fixed liquid widely used as thickening agent, emulsifier, lubricant and clarifying agent, but also as a disinfection and sterilization agent PVP-I complex used as a colloidal stabilizer and clarifying agent, can be used for beer clarification, according to the production needs of appropriate use. Uses Medical Chemicalbook, aquaculture, animal husbandry disinfectant. Used for skin and mucous membrane disinfection. PolyFilterTM molecules have amide bonds and adsorption of hydroxyl groups on polyphenol molecules to form hydrogen bonds, so it can be used as a stabilizer for beer, fruit wine/wine, beverage wine, extend its shelf life, and improve its transparency, color and taste. The product has two specifications, disposable and renewable, disposable products suitable for small and medium-sized enterprises; Recycled products require the purchase of special filtration equipment, but can be recycled and suitable for recycling in large breweries. For use in daily cosmetics, PVP and copolymer have good dispersion and film forming properties, and can be used as setting liquid, hair spray and mousse setting agent, sunscreen for hair care agent, foam stabilizer for shampoo, wave setting agent and hair dye dispersing agent and affinity agent. Add PVP to cream, sunscreen and hair remover to enhance wetting and lubrication. Using PVP's excellent surface activity, film formation, no irritation to the skin, no allergic reaction and other characteristics, it has broad prospects in the application of hair care products, skin care products, etc. It is used to absorb phenols and tannic acid from water extracts to purify plant enzymes. Used as a chromatographic adsorbent to separate aromatic acids, aldehydes and phenols. Used for clarification of beer and wine.
