Product Description

Polyvinyl pyrrolidone, or PVP, for a short period, is a non-ionic polymer that is the most distinctive, best-studied, and widely studied fine chemical among the N-vinyl amide polymers. It has developed into non-ionic, cationic grades, 3 anions, industrial grade, pharmaceutical grade, the specifications of feed grade 3, the relative molecular mass of thousands to more than one million homopolymer, copolymer and cross-linked polymer series products, and with their excellent unique properties, have been widely used.

Medicine and health
PVP has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not form any irritation to the skin, mucous membranes, eyes, etc. Pharmaceutical grade PVP is one of the three new pharmaceutical excipients advocated internationally. It can be used as a binder for tablets, granules, co-solvent for injections and flow aid for capsules. Detoxifying agent, retarding agent, lubricant and coating film forming agent, liquid preparation dispersing agent and heat sensitive drug and enzyme stabilizer, can also be used as cryoreserve agent. Used in contact lenses to increase their hydrophilic and lubricity

Food processing
PVP itself is not carcinogenic, has good food safety, can form complexes with specific polyphenol compounds (such as tannins), and is mainly used as a food clarification agent and stabilizer in food processing, such as beer, juice and wine. PVP can form complexes with specific polyphenolic compounds (such as tannins), so that it plays a clarifying and anticoagulating role in fruit juice drinks.

Daily cosmetics
Because PVP has very low toxicity and physiological inertness, it is non-irritating to the skin and eyes, and has a record of long-term use in the medical field, so it is safe to use in cosmetics. In daily cosmetics, PVP and copolymer have good dispersion and film formation, PVP has a protective colloidal effect on the emulsion, can be used in the fat and non-fat paste, as a setting liquid, hair spray and mousse setting agent, hair care agent, shampoo stabilizer foam, wave regulating agent and hair dye dispersing agent and affinity agent. Add PVP to cream, sunscreen and hair remover to improve moisture and lubrication.

Bluish
PVP has an antifouling representation performance, can be used to prepare transparent liquid detergent or detergent for heavy dirt, the addition of PVP detergent has a good anti-color effect, and can increase the cleaning ability, washing fabrics can prevent the use of synthetic detergent in skin stimulation, especially for synthetic fibers, this performance is more prominent than carboxymethylcellulose (CMC) detergent. PVP can be combined with borax as an effective ingredient in the formulation of phenol-containing disinfectant detergent.

Textile Printing & Dyeing
PVP has a good affinity for many organic dyes, and can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials to improve dyeing power and dyeing. Kirsh Y and et al. They reported that grafted copolymerization of PVP and nylon produced fabrics with better wet wrinkle resistance and moisture resistance.

Inks and pigments
PVP coated ink, transparent coating film without affecting the color, improves the gloss and dispersion of ink and pigment, improves thermal stability, and improves the dispersion of ink and ink.

TPolymer Esioactive
Polyvinylpyrrolidone, as a polymer surfactant, can be used as a dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-reprecitant agent, coagulant, co-solvent and detergent in different dispersion systems.

Catalyst preparation
Colloidal particles stabilized as active agents are used in the preparation of stone catalysts.

Other aspects
PVP can be used as a gelling agent for tertiary oil recovery to improve the oil recovery rate. As an additive for photosensitive materials, it helps to reduce emulsibility and improve the overlay capacity of developed images. It is used as a thickener, dispersion stabilizer, and bond regulator in polymerization In the paper industry as a dispersant, it is used as a cocatalyst. PVP application in separation film, light-curing resin, laser video disc, tensile strength reduction coatings, building materials, steel production and electroplating are also on the rise.
