Science
Mechanism of Action
This ingredient primarily functions as a nonionic water-in-oil emulsifier, facilitating the smooth and stable blending of oil and water phases in cosmetic products. On the skin, it acts as an emollient to provide moisture, enhancing elasticity and softness for a supple feel. It also works as a humectant, attracting and retaining hydration to prevent dryness, and reinforces the skin's lipid barrier to protect against moisture loss and external environmental stressors.

Stability
Methyl Glucose Sesquioleate is an efficient, nonionic water-in-oil emulsifier, providing effective emulsification and stability even at low concentrations. It significantly enhances emulsion viscosity, potentially reducing the need for additional thickeners, and also strengthens and rigidifies molded stick products, thereby reducing syneresis. The ingredient can also stabilize multi-phase makeup products. For elegant and long-term stable oil-in-water emulsions, it is effectively combined with PEG-20 Methyl Glucose Sesquistearate.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that methyl glucose polyethers and esters, including Methyl Glucose Sesquioleate, are safe for use in cosmetic formulations, with reported concentrations in leave-on products reaching up to 10%. It is listed in the FDA's Voluntary Cosmetic Registration Program (VCRP) and approved by regulatory authorities such as the European Cosmetics Regulation. While generally well-tolerated, there is one documented case report of an allergic reaction in a patient to Methyl Glucose Sesquistearate, a related ingredient, at a 5% concentration in petrolatum.
