PEG-20 HYDROGENATED CASTOR OIL.

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

PEG-20 Hydrogenated Castor Oil is a non-ionic surfactant and emulsifier derived from castor oil, engineered to stabilize formulations and improve ingredient distribution. It also functions as a humectant, contributing to skin hydration and product texture.

Science

Mechanism of Action

This ingredient functions primarily as a non-ionic surfactant, emulsifier, and solubilizer. Its amphiphilic molecular structure allows it to reduce the interfacial tension between immiscible liquids like oil and water, facilitating the creation of stable emulsions and ensuring uniform blending of ingredients. Beyond its foundational role in formulation stability and texture, PEG-20 Hydrogenated Castor Oil can enhance the penetration of other active ingredients into the skin. It also acts as a binding and thickening agent, supporting product consistency, and contributes a moisturizing effect by helping to maintain the skin barrier and minimize transepidermal water loss.

The CIR Expert Panel deemed PEG-20 Hydrogenated Castor Oil, among 130 related PEGylated oils, safe for cosmetic use when formulated to be non-irritating. Related PEGs are approved as direct and indirect food additives by the FDA. While ethoxylation can lead to trace amounts of 1,4-dioxane, this can be effectively managed through purification processes.
