Function of Polyvinylpyrrolidone Cas 9003-39-8:
- Thickening and stabilizing effects: Polyvinylpyrrolidone has good thickening properties and can increase the viscosity of the solution, making the solution more stable and fluid.
- Dispersion and emulsification: It can effectively reduce the attraction between particles, make solid particles or liquid droplets evenly dispersed in the solvent, and prevent them from agglomeration and precipitation.
- Complexation and adsorption: The carbonyl group and nitrogen atom in the molecular structure give it certain complexation and adsorption capabilities, and it can form complexes or undergo adsorption with many substances.
- Solubilizing and solubilizing effects: can increase the solubility of poorly soluble drugs in solvents and improve the bioavailability of drugs.
Application of Polyvinylpyrrolidone Cas 9003-39-8:
- Pharmaceutical preparation excipients: It is one of the commonly used pharmaceutical excipients, used as a binder for tablets, which can tightly combine drug particles and ensure the hardness and integrity of tablets.
- Skin care products: It is used as a thickener, moisturizer and emulsifier in skin care products such as creams, lotions, and essences to give the products good texture and stability, enhance moisturizing effects, and make the skin more moisturized and smooth.
- Oilfield development: As a gelling agent for tertiary oil recovery, it can improve the oil recovery rate of oil fields and increase oil production.
- Paint additives: added to paint, it can be used as a thickener, dispersant and leveling agent to improve the rheological properties and construction performance of the paint, make the paint more uniform and smooth during the application process, prevent sagging and peeling, and improve the covering power and gloss of the paint.
