Stable Hydroxypropyl methyl cellulose(HPMC)
CAS No.:9004-65-3
Variety of viscosity
Application :As excipients used in Pharmaceutical ,food ,health care , cosmetic grade
Conform to USP BP EP JP per your requirement
Product Characteristics
1. Appearance: HPMC is a white to light yellow powder or granular product.
2. Solubility: HPMC is nearly insoluble in anhydrous ethanol, ethyl ether and acetone. It is swelled in cold water to form a transparent or a slight cloudy solution. HPMC can be dissolved into some organic solvents and also in water-organic solvent mixed solvents.
3. Fineness(Graininess): The oversize product above 100 mesh should not exceed 5.0%.
4. With reduction of methoxyl groups content, HPMC is increased in gelling temperature and decreased in water solubility and surface activity.
Properties
1. Resistance to salting out
2. Surface activity
3. Thermal gelation
4. pH stability
5. Water retention
6. Film forming
7. Cohesiveness (Binding property)

Purpose of Application
HPMC,a multipurpose additive for pharmaceutical, can be functioned as thickener, dispersant, emulsifier, film forming agent, etc.
It is used in tablets for dressing and binding to improve solubility of the drugs and reinforce tablets’ water prevention function.
It can also be utilized as mixed suspending agent, additive for eye drops, sustainedrelease agent, etc.
HPMC can be widely used in the fields of detergent and cosmetics industries as thickener and emulsion stabilizer to improve rheologic property.
HPMC can be directly applied to food not only as emulsifier, binder, thickener or stabilizer, but also as packing material.
