PEG-30 HYDROGENATED CASTOR OIL.

Valuable CAS 61788-85-0 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-30 Hydrogenated Castor Oil is a multifunctional ethoxylated derivative of castor oil, primarily serving as an emulsifier and surfactant to stabilize oil and water mixtures. It also functions as an effective solubilizer, enabling various ingredients to seamlessly integrate into cosmetic formulations.

Summary

emulsifying surfactant solubilizer

Science

Mechanism of Action

This ingredient effectively reduces the surface tension between immiscible oil and water components, allowing them to form stable emulsions. As a solubilizer, it disperses lipid-soluble substances, such as fragrances and oils, into aqueous solutions. In cleansing applications, its surfactant properties facilitate the efficient removal of impurities from the skin. While specific clinical efficacy data for PEG-30 Hydrogenated Castor Oil is not available, related PEG-Hydrogenated Castor Oil derivatives have been noted for contributing to improved skin hydration and barrier function.

Stability

As an amphiphilic ethoxylated derivative of castor oil, PEG-30 Hydrogenated Castor Oil is water-soluble and contributes to robust formulation stability. Its inherent resistance to microbiological degradation can minimize the need for additional preservatives. For a related ingredient, PEG-40 Hydrogenated Castor Oil, optimal performance has been observed within a pH range of 5.5 to 7.0 in aqueous solutions and typical cream formulations.

Safety Profile

CIR Status
Safe as used
Max tested
100%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG-30 Hydrogenated Castor Oil is safe for use in cosmetics and personal care products at concentrations up to 100%, with no observed dermal or ocular irritation in studies. It is important to differentiate this from PEG-35 Castor Oil, a related ingredient that has shown irritation potential at 50% concentration and could increase the sensitization risk of other ingredients. Manufacturers must ensure proper purification to mitigate potential contamination risks from impurities like 1,4-dioxane. The ingredient is regulated under the general provisions of the European Cosmetics Regulation and is recognized by the FDA for its base component, castor oil.
