PEG-20 GLYCERYL OLEATE.

Valuable CAS - / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-20 Glyceryl Oleate is a versatile polyethylene glycol derivative, primarily functioning as a surfactant. It adeptly emulsifies oil and water, stabilizing formulations, and serves as an effective cleansing agent, facilitating the rinsing of impurities. Furthermore, it acts as a humectant, contributing to skin hydration.

Science

Mechanism of Action

This ingredient operates as a sophisticated surfactant, utilizing its amphiphilic structure to significantly reduce interfacial tension between incompatible phases. This enables it to powerfully emulsify oil-in-water systems and solubilize various cosmetic components, including actives and fragrances. On the skin, it functions as a humectant, establishing hydrogen bonds with water molecules to draw and retain moisture, thereby supporting long-term epidermal hydration.

Stability

PEG-20 Glyceryl Oleate is a hydrophilic emulsifier, offering inherent stability and resistance to microbial growth, which can reduce the need for additional preservatives. It is readily water-soluble and non-greasy, making it highly versatile for various cosmetic applications, particularly in forming robust oil-in-water emulsions. However, formulators should be mindful that PEGs, if oxidized, can lead to increased acidity, with some high concentration solutions showing a pH as low as 3. Successful incorporation into emulsions necessitates careful adherence to heating and cooling protocols to ensure optimal stability and performance.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Max tested
10%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEGylated alkyl glycerides, including PEG-20 Glyceryl Oleate, are safe when used in current practices and concentrations, provided formulations are non-irritating. For leave-on applications, a maximum concentration of 10% is deemed safe. Its foundational component, Glyceryl monooleate, holds FDA approval for food use and exhibits biocompatibility. Comprehensive safety evaluations have shown no evidence of genotoxicity, reproductive toxicity, phototoxicity, or a high risk of skin sensitization, classifying its irritancy potential as low.
