Summary

Emollient Skin conditioning

Science

Mechanism of Action

This ester functions by providing a rich, soft feel to the skin through its emollient properties. It creates a lightweight, occlusive film on the skin's surface that significantly reduces transepidermal water loss (TEWL), thereby enhancing skin hydration, promoting smoothness, and reinforcing the natural skin barrier function. Its structure facilitates easy absorption into the skin.
