PEG-10 GLYCERYL DIISOSTEARATE.

Valuable CAS - / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-10 Glyceryl Diisostearate is a multifunctional ethoxylated fatty acid ester primarily utilized as a surfactant and emulsifier in diverse cosmetic formulations. It effectively blends oil and water phases, ensuring product stability and enhancing spreadability, while also providing light emollient and moisturizing benefits to the skin.

Science

Mechanism of Action

This ingredient functions by significantly lowering the interfacial tension between immiscible oil and water phases, thereby creating and stabilizing robust oil-in-water or water-in-oil emulsions. On the skin, it is capable of forming a subtle, protective film which may help to minimize transepidermal water loss (TEWL), offering a mild hydrating effect. Furthermore, its emollient properties contribute to a smoother skin feel and can reduce the perception of greasiness in product textures.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed PEG compounds, including fatty ester end-capped alkoxylates such as PEG-Glyceryl Diisostearate derivatives, concluding that they are generally safe for use in cosmetics under current conditions. While a specific maximum concentration for PEG-10 Glyceryl Diisostearate was not explicitly detailed, closely related compounds like PEG/PPG-8/3 Diisostearate have been reported for use up to 5% in leave-on hair conditioners and up to 59.9% in face masks. Manufacturers are advised to ensure the stringent removal of potential impurities like ethylene oxide and 1,4-dioxane. Additionally, PEG derivatives should not be applied to compromised or damaged skin.
