What Isostearyl Neopentanoate is & what it does

Isostearyl Neopentanoate is a synthetic emollient ester formed from isostearyl alcohol and neopentanoic acid. In skincare and sunscreen formulas it acts as a lightweight skin-conditioning agent that spreads easily and leaves a smooth, non-greasy finish. It is often chosen as a silicone alternative because it gives a silky slip while helping to soften and condition the skin.
