We can produce 200,000 tons of chemical fiber oil and 200,000 tons of surfactants annually. We can supply more than one hundred types of products. Especially its polyester POY oil is an exclusively developed product in China and can totally replace imported hi-tech products.
Hydrogenated castor oil ethoxylates, also known as ethoxylated hydrogenated castor oil or hydrogenated castor oil polyoxyethylene ether, CAS No. 61788-85-0, constitute a class of non-ionic surfactants produced through the addition reaction of hydrogenated castor oil with ethylene oxide. Their molecular structure comprises a hydrophobic portion of long-chain fatty acid glycerides from hydrogenated castor oil and a hydrophilic portion of polyoxyethylene chains. This configuration ensures excellent emulsifying, dispersing, lubricating, and solubilising properties while forming stable colloidal dispersions in water and most organic solvents.
Common grades include HEL-20 and HEL-40. HEL-20 possesses a lower polyoxyethylene degree of addition, making it suitable for applications requiring strong oil-phase affinity. Conversely, HEL-40 exhibits enhanced hydrophilicity, rendering it ideal for efficient emulsification and antistatic applications within aqueous systems.
These products are extensively employed in the textile industry as spinning oil components for synthetic fibres such as polyester, polyacrylonitrile, and polyvinyl alcohol. They significantly enhance fibre lubricity and softness, reduce breakage, and improve weaving performance. Within the cosmetics and pharmaceutical sectors, they serve as O/W emulsifiers in creams, skincare products, and lotions, ensuring formulation stability. In agrochemicals, they function as pesticide emulsifiers to enhance wetting and dispersion of formulations. Within metalworking, they are employed in water-soluble cutting fluid preparations to improve cooling and lubrication efficacy. Furthermore, HEL-20 and HEL-40 serve as synthetic slurry defoamers, oilfield demulsifiers, papermaking auxiliaries, and functional components in cleaning products. Their HLB values can be precisely controlled by adjusting polyoxyethylene chain length to meet diverse industrial requirements.
Castor oil ethoxylates, also known as castor oil polyoxyethylene ether or ethoxylated castor oil, CAS No. 61791-12-6, constitute a class of non-ionic surfactants produced by the addition reaction of natural castor oil with ethylene oxide. Their molecular structure comprises castor oil triglycerides as the hydrophobic end, linked to polyoxyethylene chains as the hydrophilic end, creating a unique hydrophilic-hydrophobic balance. This endows them with excellent emulsifying, lubricating, dispersing, dissolving, and solubilising capabilities.
Compared to hydrogenated castor oil derivatives, unhydrogenated castor oil ethoxylates retain the original unsaturated structure of castor oil, thereby performing better in applications requiring a certain degree of flexibility or a lower solidification point.
The HLB value of these products can be adjusted according to the degree of polyethylene glycol addition, making them suitable for a wide range of industrial applications: in the textile industry, they are commonly used as components in spinning oils, desizing agents, and softeners to enhance fibre lubricity and antistatic properties; in pharmaceuticals and cosmetics, they serve as O/W or W/O emulsifiers, ensuring the stability and mildness of emulsions and creams; In coatings, inks, and pesticide formulations, they function as dispersants and wetting agents, improving the dispersion of pigments or active ingredients.
Furthermore, they are extensively utilised in metalworking fluids, lubricants, and detergents to enhance cooling, lubricating, and cleaning capabilities. Owing to their natural origin and biodegradability, castor oil ethoxylates are regarded as environmentally friendly surfactants, particularly suited for industries prioritising sustainability and low toxicity.
