Application Fields of Poly Vinyl Pyrrolidone

Ⅰ. Application of poly vinyl pyrrolidone in medicine and health

Poly vinyl pyrrolidone has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not cause any irritation to skin, mucous membranes, eyes, etc. Pharmaceutical grade PVP is one of the three new pharmaceutical excipients advocated internationally. It can be used as a binding agent for tablets and granules, a cosolvent for injections, and a glidant for capsules, as well as the detoxifiers, delayed effect agents, lubricating agents for eye drops and coating film forming agent. It can also be used as a low-temperature preservation agent, as a dispersant for liquid preparations and stabilizers for enzymes and heat-sensitive drugs. It can be used in contact lenses to increase their hydrophilicity and lubricity.


Ⅱ. Application of poly vinyl pyrrolidone in food processing

PVP itself is not carcinogenic and has good food safety. It can form complexes with specific polyphenol compounds such as tannins. In food processing, it is mainly used as the clarifier and stabilizer for food such as beer, fruit juice, and wine. Poly vinyl pyrrolidone can form complexes with specific polyphenol compounds such as tannins to make it play a role in clarification and anticoagulation in fruit juice beverages. The same effect can be achieved by using PVP in the production process of wine and vinegar. Cross-linked PVP is particularly widely used in beer and tea beverages. Polyphenols in beer can combine with proteins in beer to form tannin macromolecular complexes, which will seriously affect the flavor of beer and shorten its shelf life. The cross-linked poly vinyl pyrrolidone (PVPP) can complex with tannins and anthocyanins in beer, thereby clarifying the beer, improving the storage stability of the beer, and extending the shelf life. In tea beverages, the use of PVPP can appropriately reduce the content of tea polyphenols, and PVPP does not remain in tea beverages, and can be reused, greatly reducing costs.


Ⅲ. Application of poly vinyl pyrrolidone in daily cosmetics

Because PVP has extremely low toxicity and physiological inertia, it has no irritation to the skin and eyes, and has long-term use records in the medical field, so it is safe to use in cosmetics. In daily cosmetics, poly vinyl pyrrolidone and copolymers have good dispersibility and film-forming properties. PVP can protect colloids in emulsions and can be used in fatty and non-fat pastes, as styling liquid and hair spray and mousse setting agent, hair conditioner sunscreen agent, shampoo foam stabilizer, wave setting agent and dispersing agent and affinity agent in hair dye. Adding PVP to vanishing cream, sunscreen, and depilatory can enhance the moisturizing and lubricating effect.


Ⅳ. Application of poly vinyl pyrrolidone in detergent

PVP has anti-dirt re-precipitation properties and can be used to prepare transparent liquid or heavy-dirt detergents. Adding PVP to detergents has a good anti-rotation effect, and can enhance the washing ability. When washing fabric, it can prevent the irritation of synthetic detergent to skin, especially to synthetic fiber, the effect of which is more prominent than carboxymethyl cellulose detergent. Poly vinyl pyrrolidone can be compounded with borax as an effective ingredient in the phenol-containing disinfectant detergent formula. In the detergent compounded with PVP and hydrogen peroxide solid, it has the effect of bleaching and killing germs.


Ⅴ. Application of poly vinyl pyrrolidone in textile printing and dyeing

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 power and hydrophilicity. After the graft copolymerization of PVP and nylon, the fabric produced has improved wet wrinkle resistance and moisture resistance.


Ⅵ. Application of poly vinyl pyrrolidone in coatings and pigments

Paints and coatings coated with poly vinyl pyrrolidone form a transparent film without affecting the natural color, improve the gloss and dispersibility of the coatings and pigments, thermal stability, and the dispersibility of inks.
