STEARYL HEPTANOATE.

Valuable CAS 66009-41-4 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Stearyl Heptanoate is a highly effective skin-conditioning ester that serves as an occlusive agent, creating a protective barrier to minimize trans-epidermal water loss. It simultaneously functions as an emollient, contributing to a noticeably softer and smoother skin texture.

emollient skin conditioning

Science

This ingredient functions by forming a non-greasy, protective barrier on the skin's surface, effectively preventing moisture evaporation and enhancing hydration as an occlusive. It also softens and smooths the skin as an emollient, while improving formulation spreadability and absorption for a silky, non-oily finish.
