Coco-caprylate is the mixture of esters that occur when the fatty alcohols derived from coconut alcohol reacts with the fatty acid caprylic acid. What results is a lightweight, easy-to-spread emollient ingredient that smooths and softens skin.

Coco-caprylate may be plant-derived or synthetic (Paula’s Choice uses the former) and is not known to be a sensitizing ingredient.
