Sinobio Polyvinyl Pyrrolidone USP Grade CAS No 9003-39-8 Pvp K30 K60 K90 Polyvinylpyrrolidone

Product DescriptionPolyvinyl pyrrolidone / Povidone / PVP-KProduct Name: PVP-K Synonyms: Polyvinyl pyrrolidone, PovidoneCAS No.:  9003-39-8Molecular Formula:  (C6H9NO)nPovidone is a hygroscopic polymer ,supplied in white or creamy white powder or flakes,ranging from low to high viscosity & low to high molecular weight,which characterized by K Value.It's easily soluble in water and many other organic solvents,with excellent  hygroscopisty,film-forming,adhesive,chemical stability and toxicological safeness characters.Applications:In Pharmaceutical IndustryPVP-K possess excellent adhesive,film-forming,dispersing and thickening properties,and are widely used in the pharmaceutical industry.Low molecular weight PVP-K, often used as a solubilizing agent, crystallization inhibitor and suspension stabilizer in injection and ophthalmic formulations such as PVP K12,K15,K17.Medium Molecular PVP-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 PVP K25,K30.High molecular PVP-K, as highly effective binder, often used as stabilizer in oral and topical suspension, as a thickener, hydropylizing agent such as PVP K90.In Cosmetic IndustryPVP-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.
