POLYGLYCERYL-4 OLEYL ETHER OLIVATE.

Valuable / EMULSION STABILISING, SURFACTANT - CLEANSING

Polyglyceryl-4 Oleyl Ether Olivate is a plant-derived emulsifier and skin conditioning agent, originating from olive oil and polyglycerin. It facilitates the stable blending of oil and water phases in formulations while simultaneously enhancing skin hydration and smoothness.

Summary

Emulsifying Surfactant Skin Conditioning Moisturizing Emollient Emulsion Stabilizing

Science

Mechanism of Action

This ingredient functions as an advanced emulsifier and surfactant, effectively reducing surface tension to form and stabilize oil-in-water emulsions. On the skin, it establishes a breathable protective barrier that minimizes transepidermal water loss, significantly boosting moisture retention and overall hydration. It further acts as a skin conditioning agent, providing softening effects and contributing to a refined, non-greasy skin texture.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed the broader family of Polyglyceryl Fatty Acid Esters as safe for cosmetic use when formulated to be non-irritating. A closely related ingredient, Polyglyceryl-4 Olivate, is considered non-sensitizing. While generally well-tolerated, individuals with extremely sensitive or compromised skin may experience mild irritation. Direct eye contact may cause mild to moderate irritation. Specific SCCS and FDA statuses for this ingredient are not yet available.
