Hydroxypropyl methylcellulose (HPMC) 2910 E15 Supplier in China
Hydroxypropyl methylcellulose (HPMC) 2910 E15, USP42 is a semisynthetic, viscoelastic polymer, it is a cellulose ether. Hydroxypropylmethyl cellulose (HPMC) can be dissolved into some organic solvents and also in water-organic solvent mixed solvents. It does not have a gelation property when heated. HPMC is non-toxic to humans and the raw material is from cotton and wood.
Hydroxypropyl methylcellulose (HPMC) E15 is used as a film coating or adhesive agent in oral solid preparation, significantly increasing the stability, dissolution rate as well as enhancing the water-retention properties of a tablet. HPMC can also be used as a suspending agent in suspension, a matrix material for ophthalmic agent, a skeleton material for hydrophilic gel skeleton sustained-release and gastric floating tablets.
