CETEARYL RICE BRANATE.

Valuable CAS - / SKIN CONDITIONING

A sophisticated plant-derived ester that bridges the gap between botanical oils and advanced barrier repair. It provides a lightweight, non-greasy cushion that reinforces the skin's lipid matrix while delivering superior antioxidant stability.

Summary

Emollient Skin-conditioning agent Occlusive Barrier repair

Science

Mechanism of Action

This ingredient functions as a biomimetic emollient that integrates into the stratum corneum's lipid bilayer. By forming a breathable, occlusive film, it significantly reduces trans-epidermal water loss (TEWL) and supports the structural integrity of the skin barrier.
