Science
Mechanism of Action
This ingredient operates as an emollient by supplementing the skin with exogenous lipids, thereby fortifying the skin's natural barrier. Its occlusive nature creates a protective film on the skin surface, significantly reducing transepidermal water loss (TEWL) and promoting enhanced hydration. This mechanism also contributes to potential protection against inflammation. Furthermore, Isooctyl Tallate serves as a plasticizer and solvent, facilitating the uniform dissolution and dispersion of various oils, surfactants, and other key components in cosmetic formulations.
