Ethylhexyl Hydroxystearate
What is Ethylhexyl Hydroxystearate?
Ethylhexyl Hydroxystearate is a synthetic emollient ingredient created through esterification of 2-ethylhexyl alcohol and 12-hydroxystearic acid, sourced from hydrogenated castor oil. It falls into the skin conditioning category for cosmetics like moisturizers, sunscreens, lip products, and foundations. In formulations, it functions by forming a thin, lubricious film on the skin that mimics natural sebum, enhancing spreadability and providing a silky, non-greasy finish. Its branched chain structure allows better compatibility with oils and silicones, improving product stability and sensory appeal. It helps smooth surface irregularities, boosts emollience in oil-based systems, and aids in reducing transepidermal water loss through physical barrier support alongside occlusives. Widely used for its versatility in both water-in-oil and anhydrous products.
