What is C12-15 Alkyl Benzoate?

C12-15 Alkyl Benzoate is a synthetic ester formed from benzoic acid and a blend of linear alcohols ranging from 12 to 15 carbons. This clear, odorless liquid belongs to the category of emollient esters commonly used in skincare formulations like moisturizers, sunscreens, and makeup. It functions by mimicking natural skin lipids to lubricate the skin surface, enhancing product spreadability and providing a silky, non-oily finish. As a solvent, it helps dissolve fragrances and active ingredients, improving formula stability. Its low viscosity allows it to penetrate slightly between skin layers, aiding moisture retention without heaviness. In cleansers, it contributes to efficient rinsing by reducing surface tension. Derived through esterification, it offers a dry-touch alternative to heavier oils, making it ideal for lightweight textures in daily cosmetics.
