Applications of Polyvinylpyrrolidone
In the pharmaceutical industry, PVP can be used as a pharmaceutical excipient, drug carrier, slow-release agent and drug synthesis intermediate. As a pharmaceutical excipient, it can improve the taste, efficacy and stability of drugs. As a drug carrier, PVP can encapsulate drugs in its molecular structure to achieve the slow release of drugs, increase the bioavailability of drugs, and reduce adverse reactions.
In the field of cosmetics, PVP has excellent solubility, dispersibility and film-forming properties, and can be used as an additive, humectant and thickener. As an additive, it can increase the consistency and stability of cosmetics; as a humectant, it can effectively lock moisture and provide long-lasting moisture protection; as a thickener, it can increase the consistency and adhesion of products.
In addition, PVP has a wide range of applications as a plasticiser, dispersant and anti-scorch agent in rubber products, as an anti-static agent, dispersant and softener in fibre products, as a dispersant and synergist for pesticides in agriculture, and as a plasticiser and grinding aid in ceramic products.
