PEG-50 GLYCERYL ISOSTEARATE.

Valuable / CLEANSING, SURFACTANT - EMULSIFYING

PEG-50 Glyceryl Isostearate is a versatile ingredient that facilitates the harmonious blend of oil and water in formulations, stabilizing cosmetic products. It also functions as a skin conditioning agent, contributing to a soft and smooth tactile finish on the skin.

Summary

Emulsifying Surfactant Skin conditioning agent Emollient Penetration enhancer

Science

Mechanism of Action

This compound primarily acts as a surfactant and emulsifier, effectively reducing the surface tension between disparate phases to create stable emulsions. Beyond its foundational role in formulation, it provides skin conditioning and emollient properties, enhancing the skin's texture. Furthermore, certain polyethylene glycols, including this type, can act as penetration enhancers, potentially aiding the deeper delivery of other active ingredients into the skin.

Safety

Safety Profile

CIR Status

Max tested
25%
Sensitization risk Low

The CIR Expert Panel affirmed in 2002 that PEG Stearates, including the closely analogous PEG-50 Stearate, are safe for cosmetic application. They were found to be neither irritating nor sensitizing at concentrations of 25% or greater. However, application of PEGs on compromised or damaged skin should be avoided. Due to the ethoxylation process, there is a potential for trace impurities such as ethylene oxide and 1,4-dioxane; manufacturers are strongly advised to rigorously minimize these by-products to ensure product purity.
