HPMC is a white powder. It can be dissolved in water and some organic solvents, and can be dissolved in cold water. Its maximum concentration is only determined by its viscosity. The solubility changes with the change of viscosity. The lower the viscosity, the greater the solubility.
HPMC is also a non-ionic cellulose ether, not a polyelectrolyte. Therefore, in the presence of metal salts or organic electrolytes, it is relatively stable in aqueous solution, but excessive addition of electrolyte can cause gelation and precipitation.
When HPMC is heated to a certain temperature, it will become opaque, gel, and form a precipitate, but upon continuous cooling, it will return to the original solution state, and the temperature at which this gel and precipitate occur mainly depends on their lubrication Agent, suspending agent, protective colloid, emulsifier, etc.
