Polyvinylpyrrolidone K25 pharmaceutical grade (USP36, EP8.0) is regularly supplied with stable quality from TNJ Chemical
Polyvinylpyrrolidone K25 exists in white powde. It is easily soluble in water, alcohol, amine and halohydrocarbon, but insoluble in acetone and aether etc. It is also steady to acid, salt and heat, so it is widely used in cosmetics, pharmaceuticals, industrial lines etc.
Specification of Polyvinylpyrrolidone K25
Application of Polyvinylpyrrolidone K25
In Pharmaceutical Industry
Polyvinylpyrrolidone-K possess excellent adhesive,film-forming,dispersing and thickening properties,and are widely used in the pharmaceutical industry.
Low molecular weight Polyvinylpyrrolidone-K, often used as a solubilizing agent, crystallization inhibitor and suspension stabilizer in injection and ophthalmic formulations such as K12,K15,K17.
Medium Molecular polyvinylpyrrolidone-K, often used as binder in tablets,capsules and granules, as a stabilizer for oral suspensions,film-forming agent,solubilizing agent, dispersant for pigments, as an enzyme stabilizer and to improve bioavailability such as K25,K30.
High molecular Polyvinylpyrrolidone-K, as highly effective binder, often used as stabilizer in oral and topical suspension, as a thickener, hydropylizing agent such as K90.
In Cosmetic Industry
Polyvinylpyrrolidone-K are used widely in a wide range in hair care, skin care & oral care products.The products are particularly suitable for formulations where viscosity modification and film forming properties are required. PVP-K products are particularly suited to hair styling products. The medium molecular weights such as PVP K30 are preferred where viscosity is critical in applications, for example, spray. The higher molecular weight products such as PVP K90 are the best choice where high viscosity are required in applications. PVP-K is widely used in cosmetics as followings
*Hair Gels
