Ethylhexyl stearate is commonly used as an emollient to provide skin softening properties and a smooth after-feel. It acts as a lubricant on the surface of the skin to help lock in moisture. Ethylhexyl stearate can also act as a solvent for other ingredients and improve the consistency of skin care products.
Ethylhexyl stearate also goes by the name octyl stearate and falls under a category of ingredients known as stearate esters. Stearates have been assessed in several studies by the Cosmetic Ingredient Review CIR Expert Panel with a safe track record, whether used in high or low concentrations. https://www.paulaschoice.com/ingredient-dictionary/ingredient-ethylhexyl-stearate.html?q=Ethylhexyl%20Stearate&fdid=ingredients
