Science
Mechanism of Action
This ingredient operates by forming a protective lipid barrier on the skin's surface, which significantly reduces transepidermal water loss and consequently improves overall skin hydration. As an emollient, it lubricates the skin, imparting a soft and smooth feel. Its surfactant properties also contribute to stabilizing emulsion systems within product formulations.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed Glyceryl Dioleate safe for use in cosmetics, provided that the concentration of its biologically active 1,2-diester form is sufficiently low to avoid inducing epidermal hyperplasia. This safety assessment is predicated on an assumption of low dermal absorption. The FDA recognizes Glyceryl Diesters, including Glyceryl Dioleate, as Generally Recognized as Safe (GRAS) direct food ingredients.

Verdict
Glyceryl Dioleate is a valuable emollient and skin conditioner, particularly beneficial for dry and sensitive skin due to its hydrating and barrier-supporting properties, though careful formulation is required to adhere to CIR restrictions regarding the 1,2-diester content.
