COCOYL ETHYL GLUCOSIDE.

Valuable CAS 223706-84-1 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

COCOYL ETHYL GLUCOSIDE is a mild, plant-derived surfactant renowned for its ability to gently cleanse the skin by effectively reducing surface tension. It efficiently removes dirt, makeup, and excess sebum while simultaneously offering moisturizing and soothing benefits, making it particularly suitable for sensitive skin types.

Surfactant Cleansing Emulsifying Moisturizing Soothing Conditioning Foam Booster

Science

Mechanism of Action

Functioning primarily as a surfactant, COCOYL ETHYL GLUCOSIDE lowers the surface tension of liquids in cosmetic formulations. This action enables it to efficiently cleanse by helping to lift and remove fat and soil particles from the skin and hair. It also acts as an emulsifier, stabilizing oil and water phases into uniform mixtures, and enhances foam formation. Furthermore, it contributes to skin hydration by providing moisturizing, soothing, and conditioning properties, helping to prevent dryness.

Stability

This ingredient functions optimally within a pH range of 4.0 to 12.0. It remains stable in neutral and alkaline solutions but is prone to hydrolysis in strong acid solutions, breaking down into sugar and fatty alcohol. Products may exhibit cloudiness when supplied at a high alkaline pH (around 12.0), which typically resolves upon pH adjustment below 7.0.

Safety Profile

CIR Status
Safe as used with restrictions
Max tested
30%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated alkyl glucosides, including the related Coco-Glucoside, concluding their safety for cosmetic use when formulated to be non-irritating. Industry research suggests alkyl polyglucosides do not irritate skin at concentrations below 30%. Higher concentrations are acceptable in rinse-off products (e.g., up to 45% for Coco Glucoside in some washes) provided the final formulation is non-irritating. It is considered non-comedogenic and presents a low risk of irritation at typical usage concentrations, though individual patch testing is always recommended.
