Hydroxypropyl methylcellulose (HPMC) E15, USP41 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 a is non-toxic to humans the raw material from cotton and wood.
Hydroxypropyl methylcellulose (HPMC) E15 is used as a film coating or adhesive agent in oral solid preparation significantly increase the stabillity, dissolution rate as well as enhance the water-retention properties of a tablet. HPMC can be also used as a suspending agent in the suspension, a matrix material for ophthalmic agent, a skeleton material for hydrophilic gel skeleton sustained-release and gastric floating tablets.
