English description（英文原文，共 907 字符）
Product Name:Crospovidone
English Name:Crospovidone
CAS No.:25249-54-1
Aliases:Cross-linked polyvinylpyrrolidone, PVPP, Cross-linked PVP
Molecular Formula:(C6H9NO)n
Physical Properties:White or off-white free-flowing powder, odorless and tasteless. Insoluble in common solvents such as water, ethanol, and ether, but swells in water. It has a porous structure, high specific surface area, and strong hygroscopicity.
Uses:Mainly used as a tablet disintegrant, rapidly absorbing water and swelling to enhance drug dissolution rate. It is also used as a clarifying and adsorbing agent for clarification of wines and beverages and for extraction and separation of active ingredients.
Technical Specifications:
Water content ≤ 5.0%
pH value (1% aqueous dispersion) is 5.0-8.0
Particle size distribution: more than 90% passes through 200 mesh
Insoluble matter content ≤ 1.0%
Residue on ignition ≤ 0.1%
