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 it to act as a barrier, controlling the rate at which the active ingredient is released in the body. In the food industry, it serves as a stabilizer and thickener in various products, enhancing texture and consistency. Additionally, it is employed in the production of inks, adhesives, and coatings due to its film-forming properties and resistance to moisture. Its versatility also extends to the cosmetics industry, where it is used in formulations to improve the stability and texture of creams and lotions.
