Cetearyl Ethylhexanoate

What is Cetearyl Ethylhexanoate?

Cetearyl ethylhexanoate is a synthetic ester formed from cetearyl alcohol, a mixture of cetyl and stearyl alcohols, and 2-ethylhexanoic acid. Widely incorporated into skincare and haircare formulations, it serves primarily as an emollient and conditioning agent in categories like moisturizers, lotions, sunscreens, and conditioners. In products, it functions by creating a lightweight, non-oily barrier on the skin or hair cuticle, which minimizes friction, enhances product glide during application, and imparts a silky after-feel. This helps maintain surface hydration indirectly by smoothing irregularities and improving overall product performance. Its branched structure contributes to low viscosity and high stability, allowing compatibility across various formula types without greasiness or heaviness.
