What it is
Isostearyl neopentanoate is a branched ester that behaves as a dry, light emollient with good spreadability and a non-greasy after-feel. It is valued for improving the slip and texture of a formula and for helping to wet and disperse pigments and UV filters. In sunscreens it contributes to a smooth, lightweight finish rather than to UV protection.
Safety & warnings
Branched emollient esters like this are generally well tolerated and are not recognized as common allergens. Their light, non-occlusive feel makes them a popular choice in facial sunscreens.
Origin & sourcing
Synthetic ester made from isostearyl alcohol and neopentanoic acid.
