PVP K12
Kingcham
As one of the three main synthetic polymer excipients, polyvinylpyrrolidone has a wide and close influence on the pharmacokinetic properties of drugs in this product. Soluble polyvinylpyrrolidone K12 (PVPK12) is one of the main categories of polyvinylpirolidone, soluble polyvinylpyrrolidone K12, as a linear homopolymer made of n-vinyl-2-pirolidone (NVP) as a monomer. PVP K12 can be used not only as a cosolvent, stabilizer, film forming agent, emulsifier and other auxiliary preparations, but also as a carrier to wrap drugs to achieve delivery and release of drugs in the body. Polyvinylpyrrolidone, powder or aqueous solution, easily soluble in water, alcohol, amine and halogenated hydrocarbons, insoluble in acetone, ether, etc. It has a good solubility, biocompatibility, physiological inertia, film forming, membrane protection ability and a variety of organic and inorganic compound ability. It is stable to acid, salt and heat, so it has a wide range of applications. Low molecular weight PVP K12 has very good film formation, PVP K12 soluble in some solvents such as water, methanol, ethanol, etc., can be poured or coated into a film, low molecular weight PVP K12 has strong water absorption and moisturizing properties, often used in skin care cosmetics. Due to its strong dispersion and solubility, low molecule PVP K12 has a good dispersion effect, which can prevent particles from aggregating and precipitating. Besides, PVP K12 can increase the solubility of many substances in aqueous solution.
Application: It is widely used in pharmaceutical excipients, cosmetic excipients, detergent raw materials and other fields.
