Polyvinylpyrrolidone(PVP)K25 is used more than K30 and K90,due to its low viscosity.Conversely, Polyvinylpyrrolidone(PVP)K90 is used less due to its high binding properties.2.Solubilizers,Solventsand Crystallization inhibitors:Low molecular weight Polyvinylpyrrolidone(PVP)K12,K15,K17 are intended for use as solubilizing agents,dispersants and crystallization inhibitors,suspension stabilizers for injections and ophthalmic products.3.Dispersant or coprecipitator agent: Polyvinylpyrrolidone(PVP)K25 or K30 act as a comilling or coprecipitation agent in drugs which do not dissolve readily,and will greatly improve the dissolutionb rate of the drug.The method used is to mix the Polyvinylpyrrolidone(PVP) and drug,and then spray this onto a carrier,granulation or tablet.4.Suspension stabilizer: Polyvinylpyrrolidone(PVP)K25,K30 andK90 are suitable for the stabilizing of suspensions with a wide range of active ingredients;the results will be improved if Polyvinylpyrrolidone(PVP)K90 is used with PolyPolyvinylpyrrolidone(PVP).5.Film/sugar Coatings,film formers: Polyvinylpyrrolidone(PVP) K25,K30 act a film-forming agents,adhesion promoters and pigment dispersers,and are often used as sugar coating and film coating.6.Thickening agents: Polyvinylpyrrolidone(PVP)K90 is suitable for use as a thickening agent for aqueous-alcoholic solutions for oral and topical suspensions.7.Pore-former:Polyvinylpyrrolidone(PVP)K30 can be applied as pore-former in taste-masking formulations and K90 can be as pore forming agent in medical plastcis.8.Improvement bioavailability,controlled release aid: Polyvinylpyrrolidone(PVP)K12,k15,17,K30,K90 can be used to adjust the dissolving speed of some hardly soluble actives.9.Food Fields:Polyvinylpyrrolidone(PVP)K25,K30,K60,K90 can be used in dietetic tablets,e.g.Vitamin,dietary fibre tablets,sweeteners.10.Other Applications: capsule flow aid ,cleaning fluids for contact lenses,enzyme and sensitive medicines stabilization,cryoprotector.FAQQ1: Can I get some samples?A: Yes, free samples(10-20g or enough to detection)are available for most of our products, you only need to pay the shipping cost.Q2:How to confirm the Product Quality before placing orders?You can get free sample and test the quality.
