HPMC is a non-ionic cellulose ether made from refined cotton as a raw material after a series of chemical processes. It is a white or slightly yellowish powder, which is a relatively common substance in life and a viscous mixture. It has the effect of thermal gel. When it is heated above a certain temperature, the aqueous solution can become opaque, forming a precipitate and causing the solution to lose viscosity. But it will change to the original solution state after gradually cooling.
HPMC is widely used in the construction industry, and can also be used in daily necessities to play the role of thickening and water retention.
