Isostearyl IsostearateBarrier

A cushiony branched-chain ester that adds rich slip and a soft, conditioned feel.

What it does

Isostearyl isostearate is a branched-chain ester emollient with a richer, more cushiony feel than the lightest esters. It softens and conditions the skin surface, adds slip, and helps disperse pigments smoothly in balms and color products. It is a texture-and-feel ingredient rather than a skin active.
