Castor Oil Polyoxyethylene Ether EL-60 (also known as PEG-60 Castor Oil) is produced by ethoxylation of natural castor oil, appearing as a light yellow paste. Due to its unique molecular structure — the castor oil fatty acid chain provides lipophilicity, and the polyoxyethylene chain segment provides hydrophilicity — this product exhibits outstanding interfacial activity in various industrial and daily chemical formulations. It has prominent emulsifying performance for oils, waxes, and various organic phases, significantly reducing the oil-water interfacial tension and endowing the emulsion with excellent long-term stability. It is a typical oil-in-water (O\/W) emulsifier.
Another major highlight of this product is its wide compatibility. EL-60 can be freely compounded with nonionic, anionic, cationic, and amphoteric surfactants, and maintains good performance stability in acidic, alkaline, and hard water systems, giving it high application flexibility in complex formulation systems. At the same time, its solubilization and coupling abilities are outstanding. In daily chemical formulations, it can effectively solubilize fragrances, essential oils, and other insoluble components, helping to build transparent and uniform product systems.
In terms of safety and environmental protection, EL-60 is equally outstanding. It has extremely low acute oral toxicity (LD₅₀ > 5000 mg\/kg), is non-irritating to skin and eyes (OECD 404\/405), and has a negative skin sensitization test (OECD 406), belonging to the practically non-toxic level. Additionally, this product is readily biodegradable (> 60% BOD\/COD, OECD 301B), meeting the requirements for sustainable development of modern green chemicals.
