                Polyvinyl pyrrolidone (PVP for short) is a non-ionic polymer compound. It is the most characteristic, most deeply studied and most widely studied fine chemical among N-vinyl amide polymers. It has developed into 3 categories of non-ionic, cationic and anionic, 3 specifications of industrial grade, pharmaceutical grade and food grade, and homopolymer, copolymer and cross-linked polymer series products with relative molecular mass ranging from thousands to more than one million , and has been widely used for its excellent and unique properties.

Application
As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds, such as colloid protection, film-forming, cohesiveness, hygroscopicity, solubilization or agglomeration. People pay attention to its excellent solubility and physiological compatibility.

Medicine & Health
PVP has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not cause any irritation to the skin, mucous membranes, and eyes.
food processing.PVP itself is not carcinogenic, has good food safety, and can form complexes with specific polyphenolic compounds (such as tannins).

Daily Cosmetics
In the consumption structure of PVP, the cosmetics industry in developed countries accounts for 30% to 50%, and my country accounts for 70% to 80%. Because PVP has extremely low toxicity and physiological inertness, it is non-irritating to the skin and eyes, and has a long-term use record in the medical field, so it is safe to use in cosmetics.

detergent
PVP has anti-soil re-precipitation properties, and can be used to formulate clear liquid or heavy-soil detergents. Adding PVP to detergents has a good anti-rotation effect, and can enhance the cleaning ability. When washing fabrics, it can prevent synthetic detergents from Skin irritation, especially for synthetic fibers, this performance is more prominent than carboxymethyl cellulose (CMC) based detergents.

Textile
PVP has a good affinity with many organic dyes, it can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials to improve dyeing strength and hydrophilicity
Paints and Pigments

polymer surfactant
As a polymer surfactant, polyvinylpyrrolidone can be used as a dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-redeposition agent, coagulant, cosolvent and washing agent in different dispersion systems. agent.

catalyst preparation
As an active agent to stabilize colloidal particles, it is used in the preparation process of core-shell catalysts.
