English description（英文原文，共 1010 字符）
Product Name:Hydroxypropyl cellulose
English Name:Hydroxypropyl cellulose
CAS No.:9004-64-2
Aliases:Hydroxypropyl cellulose ether, Cellulose hydroxypropyl ether
Molecular Formula:[C6H7O2(OH)2(OCH2CHOHCH3)]n
Physical Properties:White to off-white powder, odorless and tasteless; soluble in polar solvents such as water, ethanol, and methanol; insoluble in non-polar organic solvents such as benzene and diethyl ether; aqueous solutions exhibit surface activity and undergo gelation upon heating to a certain temperature.
Uses:Used as a thickener, emulsifier, film-forming agent, and suspension stabilizer, widely applied in pharmaceutical preparations, cosmetics, food, and coating industries. It also functions as a binder and sustained-release material in oral solid dosage forms.
Technical Specifications:
Viscosity (2% aqueous solution, 20°C): 20–200 mPa·s, depending on grade
Hydroxypropoxy content: 50%–80%
Loss on drying: ≤5%
pH value (1% aqueous solution): 5.0–8.5
Residue on ignition: ≤0.5%
