Product Properties: Crospovidone is hygroscopic, insoluble in water and all other common solvents, but it swells rapidly in aqueous solution. It's classified as Crospovidone Type A and Type B according to the different particle sizes.
Applications: In the pharmaceutical industry, Crospovidone are widely used as 1)Disintergrating agent,2)Stabilizer for suspension,3)Moisture Absorbent, 4)Complextant of Polyphenols and Tannin for the extract formulations.
Pharmaceutical Grade PVPP is a cross-linked polyvinylpyrrolidone excipient used primarily as a disintegrant. Produced via radical polymerization, it exhibits high swelling capacity without dissolving. Its chemical structure is represented by (C6H9NO)n with CAS No. 25781-40-6.
Maintain storage below 25°C in dry environments to prevent moisture absorption. Avoid inhalation of dust during handling; use appropriate PPE. Not suitable for parenteral or ophthalmic preparations due to insolubility.
