Application
Pharmaceutical field: In pharmaceutical manufacturing, povidone is mainly used as an excipient for drugs. Common uses include as an adhesive in tablets, a film former, solubilizer and stabilizer for capsules. It can help drugs absorb better in the body and improve the bioavailability of drugs.
Cosmetic industry: In cosmetics, povidone is used as an emulsifier, moisturizer and film former, and is widely used in products such as creams, lotions, shampoos and conditioners. Its hydrophilicity and hygroscopicity enable it to help skin care products retain moisture in the skin and provide a smooth texture.
Industrial application: Due to its good film-forming and adhesive properties, povidone is also widely used in coatings, paints, adhesives and other fields, which can improve the performance and quality of these products.
Povidone Advantages
Good solubility: Povidone can dissolve quickly in water and organic solvents, and is easy to mix with other ingredients to form a uniform solution or colloid.
Strong film-forming ability: It can form a transparent and uniform film on the surface of the skin or objects, and is often used as a film-forming agent for cosmetics and drugs.
Good biocompatibility: Povidone is non-toxic, non-irritating, and can be well tolerated by the human body, so it is widely used in the field of medicines and cosmetics.
