Hypromellose HPMC（Hydroxypropyl Methyl Cellulose） as a new type of pharmaceutical excipients can be widely used in pharmaceutical preparations.
YUYU® HPMC（Hydroxypropylmethyl Cellulose） can be used as a matrix material for tablet adhesives, film coatings, and sustained-release tablets; in topical applications as a suspending and thickening agent for ophthalmic preparations and also as a gel Emulsifiers, suspending agents and stabilizers for use in the formulation of ointments and ointments.
HPMC swollen in cold water into a clear or slightly cloudy colloidal solution, almost insoluble in absolute ethanol, ethyl ether, acetone. Hypromellose gelation temperature has a great influence on the formulation of hypromellose. When the hypromellose aqueous solution is heated, phase separation occurs at a specific temperature, and a gel forming a three-dimensional network structure is precipitated.
