Science
Mechanism of Action
This ester functions primarily as an emulsifier, expertly blending and stabilizing the oil and water phases within formulations to optimize product texture and consistency. On the skin, it provides substantial conditioning, improving the skin's natural barrier function and enhancing hydration. Its efficacy stems from combining the nourishing properties of rice bran oil, which is rich in antioxidants (including vitamins B and E) and essential fatty acids, with the hydrating and emollient characteristics of polyglycerin-3.
