PEG-25 HYDROGENATED CASTOR OIL

Last update on Jul 3, 2025

PEG-25 Hydrogenated Castor Oil is a viscous yellow liquid with moisturizing and emulsifying properties. When added to skin care products, it deeply conditions the skin and leaves it soft without feeling heavy or greasy. As a solubilizer, this oil helps in mixing fragrance oils or essential oils into water-based formulas. It also stabilizes oil in water emulsions like lotions and gels. Unlike Hydrogenated Castor Oil, PEG-25 Hydrogenated Castor Oil is soluble in water and can be effectively used in a wide range of aqueous emulsions. Additionally, it has cleansing properties that make it common in micellar waters, toners, and shampoos.

What is PEG-25 HYDROGENATED CASTOR OIL used for?

PEG-25 Hydrogenated Castor Oil is a versatile conditioning, emulsifying, and solubilizing agent with numerous applications in the personal care industry. It helps evenly disperse actives, essential oils, and fragrances in water-based products. This oil effectively blends oil and water-based ingredients in a formulation and prevents their separation. Further, it offers gentle cleansing without being stripping or drying. It also enhances the foaming in cleansing products to enrich the user experience. As a mild emollient, it contributes to a soft, non-greasy feel on skin or hair. PEG-25 Hydrogenated Castor Oil is commonly found in facial cleansers, toners with essential oils, lotions, makeup removers, shampoos, conditioners, and leave-in hair sprays.

Origin

PEG-25 Hydrogenated Castor Oil is made from castor oil, which is first hydrogenated. Hydrogenated Castor Oil is the more stable form of the oil and is more resistant to oxidation. This Hydrogenated Castor Oil is reacted with 25 moles of ethylene oxide to make PEG-25 Hydrogenated Castor Oil.

Safety Profile

PEG-25 Hydrogenated Castor Oil is a safe and non-toxic oil when formulated properly. During production, it has the possibility of being contaminated with 1,4-dioxane - a potential carcinogen. Therefore, it is important that the ingredient is cosmetic grade and meets the safety standards. Additionally, PEG-25 Hydrogenated Castor Oil should be used within 1-5% only in cosmetic formulations. This oil should not be used on broken skin and should be patch tested prior to full application.
