Castor Oil Polyoxyethylene Ether EL-12 (chemical name: PEG-12 Castor Oil) is prepared by the addition polymerization of natural castor oil with 12 moles of ethylene oxide. This product is an excellent O/W emulsifier, providing efficient emulsification for various oil phases such as mineral oils, animal and vegetable oils, and organic solvents, significantly reducing oil-water interfacial tension and forming stable emulsion systems.
Due to its nonionic nature, EL-12 is highly compatible with nonionic, anionic, and cationic surfactants, offering great formulation flexibility. It maintains stable surface activity in acidic, alkaline, and hard water media, demonstrating excellent chemical tolerance. Derived from natural castor oil, it exhibits extremely low skin and eye irritation, making it a mild and low-irritation green auxiliary.
As one of the flagship products of Haian Guo Li Chemical Co., Ltd., EL-12 has mature applications in multiple industries, including cosmetics and personal care, pesticide formulations, textile auxiliaries, metalworking fluids, and industrial cleaning agents. It is a versatile, cost-effective multifunctional nonionic surfactant.

Store at temperatures between 5-40°C, keep the container sealed in a cool, dry, and well-ventilated warehouse, avoid contact with moisture to prevent moisture absorption, and keep away from strong oxidizers, strong acids, and strong alkalis. It is recommended to wear protective gloves and safety glasses during operation, avoiding direct contact with skin and eyes. Although the flash point is high (>200°C), general fire prevention measures should be observed, keeping away from ignition sources and hot surfaces.
