Triethyl citrate is widely used as a plasticizer in the production of polymers, particularly in cellulose-based plastics like cellulose acetate and nitrocellulose. It enhances flexibility, durability, and transparency of these materials, making them suitable for applications in films, coatings, and packaging. In the food industry, it serves as a food additive (E1505) to stabilize foams and emulsions, often found in baked goods, dairy products, and beverages. Additionally, it is utilized in the pharmaceutical sector as a coating agent for tablets and capsules, improving their stability and release properties. Its non-toxic and biodegradable nature also makes it a preferred ingredient in personal care products, such as cosmetics and lotions, where it acts as a solvent or emollient.
