Overall, HPMC is a versatile polymer that is used in a wide variety of products due to its ability to modify the consistency and stability of formulations.
HPMC, on the other hand, is Hydroxypropyl Methylcellulose. It is produced by alkali treatment of refined cotton and further etherified using epichlorohydrin and chloromethane as etherifying agents, resulting in a nonionic mixed ether of cellulose. The degree of substitution is typically between 1.2 and 2.0, and its properties vary based on the ratio of methoxy and hydroxypropoxy groups.
