This citric acid ester is a clear, oil-soluble liquid produced by the esterification of citric acid with ethanol. Triethyl citrate is widely used as a low-spreading emollient and solvent, as well as an active deodorant ingredient. Thanks to its ability to inhibit enzymes that break down sweat, triethyl citrate reduces the formation of body odor. Triethyl citrate is incorporated into the oil phase at a concentration of 1–5%. The final pH of the formulation should be adjusted to 4–5. If triethyl citrate is to be used as an active ingredient in hydro-alcoholic deodorant formulations, a solubilizer—such as Dermofeel G10 LW—is required.Usage concentration:  1–5%
