PEG-40 Hydrogenated Castor Oil is a nonionic surfactant and emulsifier derived from castor oil. It is produced by reacting hydrogenated castor oil with 40 units of ethylene oxide. The resulting compound is a waxy or pasty substance that is soluble in water and used primarily in cosmetics and personal care products.
🏭⚗️ Production
PEG-40 Hydrogenated Castor Oil is made by first hydrogenating castor oil to saturate its fatty acids, then ethoxylating it with ethylene oxide. The number “40” refers to the average number of ethylene oxide units added per molecule.
🔬 Properties
It is a pale yellow to amber, wax-like solid or thick liquid that is soluble in water and alcohol. It functions as a solubilizer, surfactant, and emulsifier. It is mild, non-irritating, and compatible with a wide range of cosmetic ingredients.
🧪 Applications
• Cosmetics and personal care: Used to solubilize essential oils, fragrances, and other lipophilic ingredients in shampoos, cleansers, and lotions.
• Pharmaceuticals: Acts as an emulsifier and solubilizing agent in topical formulations.
• Industrial uses: Occasionally used in specialized lubricants and chemical processing applications.
