HPMC frequently asked questions

In layman's terms, non-ion is a substance that does not ionize in water. Ionization refers to the process in which electrolytes are dissociated into charged ions that can move freely in a specific solvent (such as water, alcohol). For example, the salt that is eaten every day—sodium chloride (NaCl) is dissolved in water and ionized to produce freely movable sodium ions (Na+) that are positively charged and chloride ions (Cl) that are negatively charged. In other words, when HPMC is placed in water, it will not dissociate into charged ions, but will exist in the form of molecules.

The gel temperature of HPMC is related to its methoxy content. The lower the methoxy content, the higher the gel temperature.
