Medicine and Health
Polyvinylpyrrolidone has excellent physiological inertness, does not participate in human metabolism, has excellent biocompatibility, and does not cause any irritation to the skin, mucous membranes, eyes, etc.
Food Processing
PVP itself is not carcinogenic, has good food safety, can form complexes with specific polyphenolic compounds (such as tannic acid), and is mainly used as a clarifier and stabilizer for foods such as beer, juice, and wine in food processing agents.
Daily Cosmetics
In the consumption structure of PVP, developed cosmetics industries account for 30% to 50%, and China accounts for 70% to 80%.
Detergents
PVP has anti-fouling and redeposition properties and can be used to prepare transparent liquids or heavy-duty detergents. Adding PVP to detergents has good anti-color transfer effects, can enhance washing ability, and can prevent synthetic detergents from irritating the skin when washing fabrics, especially for synthetic fibers, which is more prominent than carboxymethyl cellulose (CMC) detergents.
Textile printing and dyeing
Polyvinyl pyrrolidone has good affinity with many organic dyes and can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, esters, nylon and fiber materials to improve dyeing power and hydrophilicity.
Coatings and pigments
Paints and coatings coated with PVP can form transparent films without affecting the original color, improve the gloss and dispersibility of coatings and pigments, improve thermal stability, improve the dispersibility of inks and inks, etc.
Polymer technology
As a high molecular surfactant, polyvinyl pyrrolidone can be used as a dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-reprecipitation agent, coagulant, cosolvent and detergent in different dispersion systems.
