Product details
Polyvinylpyrrolidone powder, referred to as PVP, is a polymer of vinylpyrrolidone. Due to their different polymerization degrees, polyvinylpyrrolidone powder is divided into soluble PVP and insoluble PVPP. Polyvinylpyrrolidone CAS 9003-39-8 is one of the three new pharmaceutical excipients, which can be used as tablets, granules, and lubricants. Polyvinylpyrrolidone Raw Materials A fluid white or nearly white powder having definite hygroscopicity. It smells slightly.
Applications of Polyvinylpyrrolidone powder
Pharmaceutical field:Tablet coating: PVP can be used as a tablet coating material to make the drug surface smooth and easy to swallow.
Binder: PVP can be used as a binder for tablets and granules to increase the viscosity and strength of the drug.
Injection: PVP can be used as a solubilizer and stabilizer for injection to improve the solubility and stability of the drug.
Eye drops: PVP can be used as a moisturizer for eye drops to relieve dry eyes.
Food field:
Beverages: PVP can be used as a clarifier and stabilizer for beverages to prevent precipitation.
Candy: PVP can be used as a binder for candy to increase the viscosity and taste of candy.
Cosmetic field:
Skin care products: PVP can be used as a moisturizer and film-forming agent for skin care products to keep the skin moist.
Hair products: PVP can be used as a styling agent for hair products to increase the styling effect of hair
Function of Polyvinylpyrrolidone powder
1. Binder:
PVP has good adhesion and can be used to bond powdered or granular materials together.
In the pharmaceutical field, PVP is often used as a binder for tablets and granules to increase the viscosity and strength of the drug, making it easy to shape and take.
2. Thickener:
PVP can increase the viscosity of the liquid and make it thicker.
In the food industry, PVP can be used to thicken beverages, juices and other products to improve the taste.
3. Stabilizer:
PVP can stabilize dispersed systems such as emulsions and suspensions to prevent precipitation or stratification.
In the pharmaceutical field, PVP can be used as a stabilizer for injections to improve the solubility and stability of drugs.
4. Film-forming agent:
PVP can form a transparent and elastic film.
In the cosmetic field, PVP can be used in skin care products and hair products to moisturize and set the skin.
5. Moisturizer:
PVP has good hygroscopicity and can keep the skin and hair moisturized.
In the cosmetic field, PVP is often used as a humectant to increase the moisture content of skin and hair.
Production methodprocess of Polyvinylpyrrolidone powder
Polyvinylpyrrolidone CAS 9003-39-8 is purified from 30% ~ 60% aqueous solution of purified 1-ethylene-2-pyrrolidone in the presence of ammonia or amine and hydrogen peroxide as catalyst at 50℃ after cross-chain homopolymerization.
