The production process involves treating cellulose with propylene oxide and methyl chloride to produce the final product, HPMC.

The production of HPMC involves two main raw materials cellulose and two chemical modifiers - hydroxypropyl and methyl groups. The primary source of cellulose is typically cotton lint or wood pulp, both rich sources of this naturally occurring polymer. These raw materials undergo a series of chemical processes to create HPMC.

PH: both HPMC and HEC are stable to common acids and alkalis. Alkali can speed up its dissolution and slightly increase its viscosity. HPMC solution is stable in the range of ph = 2-12. caustic soda and lime water can not affect HPMC properties. Hydroxypropyl methylcellulose is stable to common salts. But when the concentration of salt solution is high, the viscosity of HPMC solution tends to increase.
