PVP (Polyvinylpyrrolidone) homopolymer is a linear synthetic polymer compound polymerized from N-vinylpyrrolidone monomers. It has good water solubility, film-forming properties, adhesion and biocompatibility. It is widely used in the fields of medicine, cosmetics, food, coatings, etc.
Product characteristics
This product is a white to milky white amorphous powder, odorless or slightly odorous; tasteless; hygroscopic, soluble in water, ethanol, isopropanol, glycerol or chloroform, insoluble in acetone, ether and hydrocarbon solvents.
●This product can complex with many substances, especially compounds containing active hydrogen atoms or metal carbonyl compounds, to form solid complexes, which cause significant but reversible changes in the properties of the complexes such as solubility, volatility, stability, toxicity and irritation.
When used as an excipient, it can be used to develop many dosage forms with new functions or improve the performance of the original dosage form.
●This product is stable under normal conditions and has strong tolerance to heat, acid and alkali.

FAQ
Q: What are the advantages of PVP in pharmaceutical tablets compared to other binders?
A: PVP has good water solubility and viscosity, which can make the drug powder tightly combined, and the tablets made are of moderate hardness and good disintegration performance. Moreover, it has good biocompatibility and high safety, and will not have adverse effects on the human body. At the same time, it can also improve the stability of the drug and extend the shelf life.
Q: In cosmetics, how does PVP improve the use of products?
A: In styling products, PVP can form a flexible film, the styling effect is long-lasting and will not make the hair stiff. In skin care products, it acts as a moisturizer and lubricant, which can enhance the moisturizing and ductility of the product, making it easier for the skin to absorb the active ingredients and comfortable after use.
