What it is
Dipentaerythrityl Hexahydroxystearate is an ester formed between dipentaerythritol and hydroxystearic acid. The branched, multi-armed structure gives it a thick, cushiony texture, so it is used to add body and a rich emollient feel to anhydrous and emulsion products. In sun-care items such as lip balms and sticks it helps structure the base and improve skin feel.
Safety & warnings
Polyol fatty-acid esters of this type are generally well tolerated and non-sensitizing. Heavy, occlusive esters can feel rich on the skin, but this ingredient is not commonly associated with breakouts in finished products.
Origin & sourcing
Synthetic ester made from dipentaerythritol and hydroxystearic acid, the latter typically derived from vegetable oils.
