What Is PEG (Polyethylene Glycol)?

PEGs are a broad class of synthetic ingredients with many different uses. PEGs can be used in cosmetics as humectants (attract moisture to skin), emulsifiers, thickeners, solvents, or softeners. While there are no current regulatory limits on PEGs, they are in the spotlight due to the potential presence of 1,4 dioxane which can be created during the manufacturing of the raw material.1,4 dioxane is restricted above certain levels.


Origins closely monitors the purity of the PEGs we use to ensure any presence of 1,4 dioxane complies with recommended maximum trace levels of 10 parts per million (ppm or 0.001%) in finished cosmetic products.
