Hypromellose, also known as hypromellose, is a kind of nonionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer, often used as a lubricant, water-retaining agent in construction, or as a thickener and binder in detergents.

Appearance: White or off-white fibrous or granular powder.

Stability: Solids are flammable, unlike strong oxidizing agents.
Particle size: the pass rate of 100 mesh is greater than 98.5%; the pass rate of 80 mesh is 100%.
Solubility: Soluble in water and some solvents, such as ethanol/water, propanol/water, etc. in proper proportions. Aqueous solutions are surface active. High transparency, stable performance, different specifications of products have different gel temperatures, solubility changes with viscosity, the lower the viscosity, the greater the solubility, the performance of different specifications of HPMC has certain differences, and the dissolution of HPMC in water is not affected by the pH value .
