Application
Triethyl Citrate serves multiple purposes across various industries due to its distinct properties. It is primarily used as a flavoring agent in foods, enhancing taste while also acting as a high boiling solvent and plasticizer. In the pharmaceuticals sector, it functions as a plasticizer, aiding in the coating of capsules, tablets, and other formulations to achieve desired release profiles such as taste masking or sustained release. In the cosmetics and personal care industry, Triethyl Citrate is valued for its natural deodorizing and skin care properties. It is also employed as a plasticizer and humectant for cigarette filters, as well as a stabilizing agent in food processing, specifically to enhance the whipping of organic egg whites. Overall, its versatility and efficacy make it an integral component in many products, ranging from food and pharmaceuticals to cosmetics and personal care items.
