Triethyl Citrate (TEC)

Triethyl Citrate (TEC) is a biodegradable, skin-friendly ester derived from citric acid, widely used in perfumery as a solvent, fixative aid, and stabilizer. It is especially valued for its ability to improve fragrance longevity and blend stability without interfering with the original scent profile.

TEC has a light texture and excellent compatibility with a wide range of aromatic materials. It helps slow down the evaporation of volatile notes, making it a preferred ingredient in fine fragrance, deodorants, and long-lasting perfume oils. Its non-greasy feel and mild nature also make it suitable for sensitive skin formulations.
