Science
Mechanism of Action
This ingredient functions as both a skin conditioning agent and a surfactant, forming a complex mixture through the transesterification of Macadamia Ternifolia Seed Oil and PEG-8. Its PEGylated structure grants it water solubility, enabling its incorporation into water-based formulations. It imparts emollient and moisturizing benefits from its macadamia oil component, which is notably rich in monounsaturated fatty acids like oleic and palmitoleic acids. On the skin, it works to smooth, soften, and hydrate, contributing to improved elasticity and supporting cellular regeneration.
