Tri-C12-13 Alkyl Citrate
What is Tri-C12-13 Alkyl Citrate?
Tri-C12-13 Alkyl Citrate is a synthetic ester derived from citric acid reacted with a blend of dodecanol and tridecanol, which are straight-chain alcohols containing 12 to 13 carbon atoms. This produces a colorless, low-viscosity liquid commonly incorporated into skincare formulations as an emollient and skin conditioning agent. It functions by lowering surface tension in products, enabling smoother application and a velvety after-feel without greasiness. In moisturizers, serums, and lotions, it fills minor surface imperfections on the skin, enhancing softness and flexibility while supporting moisture retention alongside humectants and occlusives. Its lightweight profile makes it suitable for oil-free or mattifying products, and it offers stability across various pH levels and temperatures. Primarily used in leave-on cosmetics, it provides a silicone-like slip derived from renewable citric acid sources.
