Science
Mechanism of Action
On the skin, PEG-200 Glyceryl Stearate acts primarily as an emollient by forming a non-occlusive barrier, which significantly reduces transepidermal water loss and maintains optimal hydration. This action lubricates, conditions, softens, and smooths the skin's surface. Additionally, it exhibits antioxidant properties and helps stabilize the pH of a formulation, preventing it from becoming overly acidic or alkaline.
