POLYGLYCERYL-2 TETRAOLEATE.

Valuable CAS - / SURFACTANT - EMULSIFYING

Polyglyceryl-2 Tetraoleate is a versatile water-in-oil (W/O) emulsifier adept at forming stable, finely dispersed emulsions, even within complex formulations. Beyond its primary function in blending oil and water, it also offers notable moisturizing and skin conditioning benefits, contributing to enhanced skin barrier integrity.

Summary

emulsifying emollient surfactant skin conditioning

Science

Mechanism of Action

This ingredient functions as an emulsifying surfactant by effectively reducing the interfacial tension between disparate oil and water phases, thereby creating robust water-in-oil emulsions. It efficiently disperses within the oil phase, promoting rapid and uniform pigment dispersion and enhancing the longevity of sunscreen films. Moreover, Polyglyceryl-2 Tetraoleate contributes to skin hydration and conditioning by solubilizing fat-soluble active ingredients and mitigating transepidermal water loss, thus supporting a healthier skin barrier.
