Science
Mechanism of Action
This ingredient operates as a multifunctional ester, adept at forming stable emulsions that integrate oil and water phases, thereby enhancing product texture and uniform spreadability. On the skin, it acts as a mild surfactant, effectively binding with oil and dirt for gentle removal without leaving a greasy residue. Furthermore, it delivers emollient and moisturizing properties, contributing to improved skin hydration and softness. Its relatively high molecular weight ensures its action remains at the skin's surface, and it can also solubilize active ingredients, fragrances, and colorants.
