Hydroxypropyl methylcellulose, abbreviated as HPMC, is a variety of nonionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer that is often used in ophthalmology as a lubricant or as an excipient or excipient in oral medications and is found in a wide variety of commodities.
In addition, as a food additive, hypromellose can play the following roles: emulsifiers, thickeners, suspending agents, and animal gelatin substitutes.
HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
Hydroxypropyl Methyl Cellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic,detergent,paints,as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.We can provide the regular grade HPMC, we also can provide modified HPMC according to customer re
