Science
Mechanism of Action
This ingredient functions by bridging oil and water phases, acting as an effective emulsifying agent in formulations. On the skin, it serves as a mild surfactant, aiding in the solubilization and removal of oil-based dirt and makeup. As an emollient, it helps to soften and smooth the skin. Furthermore, similar to other Polyethylene Glycols, it can attract and bind water molecules, potentially reducing transepidermal water loss and supporting the skin's moisture barrier.
