Ethylhexyl Polyhydroxystearate
What is Ethylhexyl Polyhydroxystearate?
Ethylhexyl Polyhydroxystearate is a synthetic polyester ingredient produced by esterifying polyhydroxystearic acid, derived from castor oil's ricinoleic acid, with 2-ethylhexyl alcohol. This creates a high-molecular-weight, waxy, lipophilic substance commonly incorporated into color cosmetics such as lipsticks, foundations, mascaras, and eyeliners. In formulations, it functions primarily as a viscosity controller, thickening anhydrous products to improve stability and application. It also serves as a film former, promoting adhesion to skin and hair for extended wear, and as a skin conditioning agent that softens the skin surface without greasiness. Its non-polar nature makes it ideal for oil-based systems, enhancing spreadability and providing a matte, velvety finish.
