Description

Peg-18 Castor Oil Dioleate is a non-ionic surfactant and emollient derived from castor oil, chemically modified with polyethylene glycol (PEG) and oleic acid. This versatile compound is valued for its excellent emulsifying, solubilizing, and skin-conditioning properties, making it a key ingredient in formulations requiring stable oil-in-water emulsions and enhanced spreadability. It is primarily needed by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating creams, lotions, and topical preparations.

Application

• Primary emulsifier and co-emulsifier in cosmetic and personal care creams and lotions.
• Skin-conditioning agent and emollient in body butters, moisturizers, and sun care products.
• Solubilizer for fragrances, essential oils, and lipophilic active ingredients in aqueous systems.
• Key component in pharmaceutical topical ointments and dermatological preparations for enhanced drug delivery.
• Used in hair care formulations such as conditioners and styling products to impart softness and manageability.
• Industrial applications as a lubricant additive and emulsifier in specialty chemical formulations.
