Science
Mechanism of Action
On the skin, PEG-7 Glyceryl Cocoate functions as an emollient, forming a non-greasy layer that helps reduce transepidermal water loss, contributing to a smooth and hydrated complexion. It also acts as a humectant, actively attracting moisture to the skin. In its role as a surfactant and cleansing agent, it lowers surface tension, allowing water to mix with and lift away oil and impurities gently, without compromising the skin's natural barrier. Furthermore, it serves as an emulsifier, stabilizing oil and water phases to maintain product consistency, and as a solubilizer, enabling oil-soluble ingredients like essential oils to disperse effectively in water-based formulations.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined PEG-7 Glyceryl Cocoate to be safe for use in cosmetics. It is deemed safe for rinse-off products and can be incorporated into leave-on formulations at concentrations up to 10.0%. A notable concern is the potential for trace contamination with 1,4-dioxane, a byproduct of the ethoxylation manufacturing process, though this can be effectively minimized through purification. Due to its petrochemical origin and the potential for 1,4-dioxane, it is generally prohibited in certified organic cosmetic products. For individuals with very sensitive skin, a patch test is recommended before widespread use.
