Science

Mechanism of Action

This ingredient functions through several distinct mechanisms in skincare. As an emollient, it effectively softens and smooths the skin, imparting a lightweight, silky sensation and delivering sustained moisturizing benefits, particularly advantageous for dry or compromised skin conditions. Its dual role as an emulsifier and co-emulsifier facilitates the stable formation of oil-in-water emulsions by judiciously lowering interfacial tension. OLIVE OIL PEG-7 ESTERS also acts as a gentle secondary cleansing agent, capable of dissolving and removing oil-based impurities without disrupting the skin's essential moisture barrier. Furthermore, it serves as a solubilizer, enabling the homogenous dispersion of lipophilic components, such as essential oils and fragrances, within aqueous formulations. It is also noted for its refatting capabilities, aiding in the restoration of epidermal lipids, and its capacity to mitigate the irritating potential of surfactant systems.
