Ethyl cellulose is widely used as a coating material in the pharmaceutical industry to create controlled-release tablets and capsules. Its water-insoluble nature allows for the gradual release of active ingredients, enhancing drug efficacy and patient compliance. In the food industry, it serves as a stabilizer and thickener in various products, improving texture and shelf life. It is also used in cosmetics to improve texture and product stability. Additionally, it is employed in the production of adhesives, inks, and coatings, where it provides durability and flexibility. Its film-forming properties make it valuable in the creation of protective coatings for electronic components and other industrial applications.
