What is POvidone K30? What does it do?
The chemical name of POvidone is polyethylpyrrolidone, POvidone K30 is a 1-vinyl-2-pyrrolidone homopolymer obtained by polymerization of pyrrolidone and pyrrolidone monomer under pressure under the action of catalyst, the molecular formula is (C6H9NO)n, where n represents the average number of 1-vinyl-2-pyrrolidone chain links. According to the calculation of anhydrous matter, nitrogen (N) should be 11.5% ~ 12.8%. According to the viscosity of solution expressed by K value, povidone products are divided into different types. Main performancePovidone K30 has good hygroscopicity, film formation, complexation and physiological compatibility, and has the ability to compound a variety of organic and inorganic compounds, stable to acid, salt and heat, and has a wide range of uses. It can be used as binder of tablets and particles, co-solvent and stabilizer of injections, flow aid of capsules, dispersant of liquid preparations and colorants, stabilizer of enzyme and heat-sensitive drugs, co-precipitating agent of insoluble drugs, detoxifying agent…

Introduction to the application of pharmaceutical grade POvidone K30
Pharmaceutical grade POvidone K30 Povidone has the properties of bonding, thickening, dispersion, film formation and complexation, so it can be used as a binder for particles and tablets. Co-solvent and stabilizer for injection, film forming agent and pigment dispersing agent for coating, co-precipitation agent for insoluble drug, delay agent and lubricant for ophthalmic drug and sustained release agent for controlled release dosage form, etc. This product is often used as a tablet adhesive and can dissolve in water and ethanol to become a viscous viscous liquid, which is a good adhesive. PVP has a variety of specifications due to molecular weight or viscosity, the average molecular weight of K30 commonly used in tablet preparation is 6000, and 10%(w/w) aqueous solution has a certain viscosity. For drugs sensitive to moisture and heat, the organic solution of PVP (generally ethanol solution) can be used for granulation, which can avoid the influence of…
