Hydroxypropyl methylcellulose, commonly known as HPMC, is a semi-synthetic polymer derived from cellulose. It serves as a multifunctional excipient due to its excellent film-forming ability, high viscosity, and pH stability. In solid dosage forms, HPMC acts as a binder, ensuring the cohesion of powders into tablets. Its thermal gelation property also makes it an ideal candidate for sustained-release matrix tablets, where it controls the release of active ingredients by forming a viscous gel layer that slows down drug dissolution.

Another important application of HPMC ether is in the cosmetics and personal care industry. It is used in creams, lotions, shampoos, and other products as a thickener, emulsifier, and film-former. HPMC ether helps to improve the spreadability, texture, and stability of the product, as well as enhance the adhesion to the skin or hair. It is also used in sunscreen lotions and anti-aging creams to provide a smooth and even application while protecting the skin from UV rays and free radicals.
