PVP POvidone introduction Polyvinylpyrrolidone (PVP) is a water-soluble polymer formed by linear polymerization of N-vinylpyrrolidone (NVP). Its molecular structure formula is shown in Figure 1.1. In 1938, German chemist Reppe first used acetylene as raw material to synthesize PVP. So far, PVP has developed into non-ionic, cationic, anionic 3 categories, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties are widely used. PVP not only has the general properties of water- soluble polymers, such as colloidal protection, film formation, bonding, hygroscopicity, thickening, condensation and complexation ability with some compounds, but also has been paid attention to by people for its excellent solubility and physiological compatibility. In the synthetic polymer products, such as PVP is soluble in water, but also soluble in most organic solvents, extremely low toxicity, physiological…

In recent years, the good characteristics of water-soluble polymers have made them widely used in the field of cosmetics, and many cosmetics have the addition of water-soluble polymer compounds. The consumption of water-soluble polymer compounds in the cosmetics industry ranks fifth after that of paper, textile, food and adhesives. Before the 1950s, people mainly used natural polymers, such as yarrow gum, acacia gum, gelatin, casein gum, etc., due to the instability of its source and quality, as well as its vulnerability to microbial contamination, the 1960s began to gradually be replaced by semi-synthetic polymers such as cellulose derivatives and synthetic polymers such as vinylpyrrolidone polymers. Due to the special requirements of cosmetics, the high safety and stability of PVP polymers, their compatibility with many other compounds, and their unique and excellent solubility make them the leading products of water-soluble synthetic polymers used in the cosmetics industry. In the structural consumption…

Crosslinked POvidone White powder, insoluble in water, can swell in water Used as beer, drink, cider, etc Clarifier and stabilizer are also done A disintegrator for tablets.   The role of PVPP(polyvinylpyrrolidone) in beer stabilization has been recognized in the widespread adoption of the beer industry. PVPP can selectively adsorb polyphenols that cause cold turbidity and permanent turbidity without adverse effects on beer. This allows brewers to guarantee that the beer will maintain a clear,inviting appearance when it reaches consumers during its stated shelf life. Considering the mechanism of beer colloid instability, beer stability can be effectively realized by using PVPP. Disposable and recycled materials can be used according to the brewer’s requirements. Their performance and use in breweries are well established. To ensure effective stability,PVPP can be used with other beer stabilizers such as silica gel, tannin and papain. A novel mixture of PVPP+ silicon dry gel is derived…
