Triisostearyl Citrate
What is Triisostearyl Citrate?
Triisostearyl citrate is a triester formed from citric acid and isostearyl alcohol, a branched-chain fatty alcohol derived from vegetable oils. This synthetic ingredient belongs to the class of emollient esters commonly used in cosmetics, particularly in anhydrous products like lipsticks, lip glosses, and solid bases. It functions by providing lubrication and slip, allowing products to glide smoothly on the skin without drag. As a skin conditioning agent, it helps maintain the skin's barrier by depositing a thin film that mimics natural sebum, promoting suppleness. In formulations, it enhances stability and sensory attributes, such as a non-sticky, velvety finish. Its low polarity makes it compatible with oils and waxes, improving spreadability and wear resistance in makeup.
