What is Hydroxypropyl Cellulose CAS 9004-64-2?
Basic characteristics
Molecular formula: Usually expressed as \ceC3H7O or \ceC36H70O19 (polymer structure), with a wide molecular weight range (several thousand to several million Da).
Appearance: White or off-white powder/granules, odorless and tasteless, flammable, thermoplastic.
Solubility
Soluble in polar solvents such as cold water, methanol and ethanol;
It is insoluble in hot water (precipitates when the temperature is above 38℃), ether, benzene and other non-polar solvents.
Thermal stability
Carbonization temperature: 280-300℃, color change temperature: 190-200℃
Flash point: 492.8℃, Boiling point: 891.2℃.
Solution characteristics:
The aqueous solution has pseudoplasticity (viscosity increases with the increase of concentration);
A liquid crystal state can be formed at high concentrations.
Hydroxypropyl Cellulose CAS 9004-64-2 Use
Pharmaceutical industry
Disintegrant/Binder (L-HPC) :
Wet granulation dosage: 5% - 20% Powder tablet pressing: 5% - 20%.
Coating material (H-HPC) : Forms a water-resistant film to improve the sustained release of drugs.
Food industry
Thickener/emulsifier: Used in jams, condiments and beverages, with a dosage of 0.05% - 2.0%.
Usage: Dissolve in cold water and then mix with the raw materials to avoid precipitation caused by high temperature.
