Triethyl Citrate (CAS 77-93-0) is a biodegradable citric acid ester supplied as a clear, odorless liquid, used as a plasticizer in food-contact materials and pharmaceutical tablet coatings, as a fragrance fixative and deodorant active in cosmetics, and as a stabilizer and flavor carrier in food processing. It is a clear, odorless liquid known for its exceptional biocompatibility and safety profile in sensitive consumer products.
In the cosmetic industry, it is a preferred fragrance fixative and active ingredient in deodorants due to its enzyme-inhibiting properties. It maintains high stability and acts as an effective foaming stabilizer in various food and personal care applications.
As an eco-friendly alternative to phthalates, TEC is widely used in Food-Contact materials and pharmaceutical tablet coatings. Its low volatility and high efficiency make it an indispensable specialty chemical for sustainable polymer processing and coating technologies.
