HPMC is also employed in the formulation of capsules, particularly vegetarian capsules. As a non-gelatin alternative, HPMC is suitable for vegetarian and vegan formulations, which are increasingly in demand. Its excellent film-forming properties enable the production of capsules that are stable, customizable in terms of dissolution rates, and capable of delivering drugs effectively. HPMC capsules are manufactured through a process that involves the use of water rather than organic solvents, leading to a more eco-friendly production method.

The physical and chemical properties of hydroxyalkyl cellulose can be tailored by adjusting the degree of substitution and the molecular weight during its synthesis. This adaptability allows manufacturers to customize HAC for specific applications, meeting the diverse needs of various industries. Furthermore, HAC is environmentally friendly, as it is derived from renewable biomass (cellulose) and is biodegradable, making it an attractive alternative to synthetic polymers.

In the pharmaceutical sector, the combination of HPMC and SDS is particularly beneficial in developing oral dosage forms and topical applications. For oral formulations, the gel-forming ability of HPMC can be combined with the surfactant properties of SDS to enhance solubility and bioavailability of drugs. For instance, poorly soluble drugs can benefit from increased wettability due to SDS, while HPMC controls the release rate through its gel matrix.

Hydroxyethyl cellulose (HEC) is a water-soluble polymer derived from cellulose, which is extensively used in various applications including pharmaceuticals, cosmetics, construction, and food products. The manufacturing process of HEC involves several critical steps, beginning with the selection of raw materials and culminating in the purification and formulation of the final product.
