Isostearyl Linoleate
What is Isostearyl Linoleate?
Isostearyl Linoleate is a synthetic ester created by combining isostearyl alcohol, a branched-chain fatty alcohol derived from natural fats, with linoleic acid, an omega-6 polyunsaturated fatty acid obtained from plant sources like safflower or soybean oils. It falls into the emollient and skin conditioning category in cosmetics, appearing in products such as creams, lotions, lipsticks, and foundations. This ingredient functions by replicating skin's lipid structure, smoothing surface irregularities for a silky feel and better product glide. Its non-oily profile allows easy absorption, enhancing formulation stability and aiding in barrier repair through lipid replenishment, which helps curb water evaporation from the skin when used alongside occlusive agents.
