PEG-5 GLYCERYL OLEATE.

Valuable / SURFACTANT - EMULSIFYING

PEG-5 Glyceryl Oleate is a versatile, hydrophilic ingredient functioning primarily as an emulsifier to stabilize oil-in-water mixtures. It also acts as an emollient, conditioning the skin by enhancing moisture retention and reducing transepidermal water loss, while offering mild co-surfactant properties for cleansing formulations.

Summary

Emulsifying Emollient Surfactant/Cleansing

Science

Mechanism of Action

This ingredient operates as a hydrophilic emulsifier, crucial for creating stable emulsions by uniformly dispersing oil and water phases. As a nonionic co-surfactant, it contributes to the efficacy of cleansing products by aiding foam generation and purification. On the skin, it serves as an emollient and skin-conditioning agent, leveraging its similarity to natural skin lipids to soften, smooth, and improve barrier function, effectively binding moisture and minimizing transepidermal water loss. Its re-fatting capabilities additionally help to counteract the potential drying effects of other surfactants.

Safety

Safety Profile

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

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Glyceryl Oleate and the broader category of 'PEGylated Alkyl Glycerides' (including PEG-5 Glyceryl Oleate) are safe as used in cosmetics when formulated to be non-irritating. Specific studies showed non-irritancy for Glyceryl Oleate at 15% and within formulations at 5%. While allowed for use in EWG VERIFIED products, manufacturers must adhere to strict contamination restrictions regarding potential impurities like ethylene oxide and 1,4-dioxane resulting from the ethoxylation process. The FDA lists 'PEG Oleate' as a food additive under 21 CFR 175.300.
