Summary

emollient skin conditioning solvent rheology modifier spreadability enhancer

Science

Mechanism of Action

This ingredient functions by creating a smooth, non-greasy film on the skin's surface, which actively aids in moisture retention and overall skin hydration. As a synthetic emollient ester, it enhances the effortless application and spread of cosmetic formulations and acts as a proficient delivery vehicle for other oil-soluble active ingredients into the uppermost layers of the skin. Furthermore, it skillfully modifies formula rheology, effectively reducing the heavy or oily sensation often associated with components like sunscreen agents or pigments, and serves as an effective solvent for solid UV absorbers.
