In the pharmaceutical industry, HPMC serves multiple roles. It is often used as a binder, film former, and controlled-release agent for tablets and capsules. HPMC’s ability to form a gel in the presence of water makes it an ideal excipient for sustained-release formulations, where it can help regulate the release of active ingredients over time. Additionally, its non-toxic nature and compatibility with various drugs make it a preferred choice for many pharmaceutical formulations.

Chemical Structure and Properties

In the food industry, HPMC serves as a thickening, stabilizing, and emulsifying agent. Its solubility in water makes it an ideal ingredient in sauces, dressings, and dairy products, where it contributes to the desired texture and mouthfeel. Moreover, HPMC is often used as a fat replacer in low-fat food products, enhancing their consistency without compromising quality.
