PEG-20 METHYL GLUCOSE DISTEARATE.

Valuable CAS 119831-19-5 / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

PEG-20 Methyl Glucose Distearate is a versatile nonionic emulsifier and skin conditioning agent, primarily utilized to expertly blend oil and water components in cosmetic formulations. It also functions as a mild surfactant and viscosity-increasing agent, significantly enhancing emulsion stability and product texture while imparting a soft feel to the skin. The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed its safety when formulated appropriately to be non-irritating.

Emulsifier Skin Conditioning Agent Surfactant Viscosity Increasing Agent

Science

Mechanism of Action

This ingredient operates as a nonionic oil-in-water emulsifier, effectively integrating immiscible oil and water phases within cosmetic preparations. Beyond its primary role in emulsion creation and stabilization, it acts as a skin conditioning agent to soften and smooth, a mild surfactant to aid cleansing, and a viscosity enhancer to refine product consistency and contribute to a luxurious skin feel.

Dusting Analysis

Not commonly dusted

PEG-20 Methyl Glucose Distearate is a functional ingredient (emulsifier, viscosity enhancer) that is effective at low concentrations. Its presence, even at modest percentages, directly contributes to product formulation and stability, rather than being an 'active' ingredient whose low concentration might imply dusting for marketing purposes.

The CIR Expert Panel concluded that methyl glucose polyethers and esters, including PEG-20 Methyl Glucose Distearate, are safe for use in cosmetics when formulated to be non-irritating. A specific maximum use concentration for this ingredient has been reported at 0.05% in lipsticks. For the broader group of methyl glucose polyethers and esters, general use concentrations extend up to 4% in leave-on products and 15% in rinse-off products. PEG compounds in general hold a 'Generally Recognized As Safe' (GRAS) designation by the FDA for specific food additive applications.
