What it is
Isodecyl neopentanoate is a liquid ester that spreads easily and leaves a light, dry, non-greasy after-feel. It softens and conditions the skin and helps disperse other oil-soluble ingredients, including organic UV filters, evenly through a formula. In sunscreens it is valued for improving spreadability and reducing heaviness.
Safety & warnings
Isodecyl neopentanoate is generally well tolerated and is considered a low-irritation emollient with a low sensitization profile. It is regarded as having a low comedogenic potential, though very oil-prone skin may prefer to patch test rich ester blends.
Origin & sourcing
It is a synthetic ester made by combining isodecyl alcohol with neopentanoic acid.
