PEG-30 SORBITAN TETRAOLEATE.

Valuable / SURFACTANT - EMULSIFYING

PEG-30 Sorbitan Tetraoleate is an advanced ethoxylated sorbitan ester, serving as a multifunctional surfactant. It is primarily utilized for its robust emulsifying and solubilizing properties, enabling the stable incorporation of oil and water phases within diverse cosmetic formulations.

Science

Mechanism of Action

As a non-ionic surfactant, PEG-30 Sorbitan Tetraoleate effectively reduces the surface tension at the interface of immiscible liquids, facilitating the creation and stability of emulsions. Its amphiphilic molecular structure, comprising both lipophilic and hydrophilic segments, enhances the miscibility of oil-soluble ingredients within aqueous systems. This mechanism also supports its role in cleansing, where it aids in dispersing and removing oily impurities and dirt from skin and hair surfaces.

Key findings

  1. 01 The CIR Expert Panel found PEG Sorbitan/Sorbitol Fatty Acid Esters, including PEG-30 Sorbitan Tetraoleate, to be safe for use in cosmetics at concentrations up to 25%, with the critical restriction against use on damaged skin.

Dusting Analysis

Not commonly dusted

This ingredient is a functional component essential for formulation stability rather than an active touted for direct skin benefits, therefore it is not commonly subject to 'dusting' or overstatement of efficacy.

Stability

Polyethylene glycols and their derivatives are generally known for their broad solubility characteristics and favorable skin tolerance. While no specific optimal pH range for PEG-30 Sorbitan Tetraoleate was identified, PEGs are typically stable across a wide pH range and do not often require additional preservation against microbial growth.

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG-30 Sorbitan Tetraoleate is safe for cosmetic use at concentrations not exceeding 25%. However, it is explicitly not recommended for use on damaged or compromised skin. As a byproduct of ethoxylation, trace amounts of 1,4-dioxane may be present, though controlled through rigorous purification. It is recognized as safe for specific, limited food uses by the U.S. FDA, and in the European Union, its use is permitted provided all components are plant-derived.
