PEG-54 HYDROGENATED CASTOR OIL.

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

PEG-54 Hydrogenated Castor Oil is a versatile, PEGylated derivative of hydrogenated castor oil, primarily functioning as an emulsifier and solubilizer. It also offers valuable skin-conditioning benefits, acting as both an emollient and a humectant to support skin barrier function and hydration.

Emulsifying Surfactant Solubilizer Skin Conditioning (Emollient) Humectant Cleansing Fragrance Functional

Science

Mechanism of Action

This ingredient operates by significantly reducing surface tension, which is crucial for forming stable emulsions between immiscible liquids like oil and water. As a surfactant, it aids in cleansing by effectively dispersing and suspending oil-based impurities for easy removal. Its solubilizing capability allows for the homogeneous integration of lipophilic compounds into aqueous formulations. Additionally, the hydrogenated castor oil component imparts emollient properties, forming an occlusive layer to minimize transepidermal water loss, while its ricinoleic acid's hydroxyl groups contribute humectant benefits, drawing moisture to the skin.

100%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that PEGylated oils, including PEG-54 Hydrogenated Castor Oil, are safe for cosmetic use when formulated to be non-irritating. Related ingredients, specifically PEG-30 and PEG-40 Hydrogenated Castor Oil, have been found safe at concentrations up to 100%. Manufacturers can control trace amounts of 1,4-dioxane, a by-product of ethoxylation, through rigorous purification steps. Furthermore, the FDA permits castor oil as a flavoring agent and certain PEG Castor Oil ingredients (molecular weight 400-3,000) for indirect food additive applications, underscoring a favorable safety profile.
