It has higher solubility in cold water than in hot water and good emulsifying properties for mineral oil. 1% aqueous solution pH = 6-8. The HLB value is 13.1% aqueous solution cloud point ≥ 85 °C. Acid, hard water and inorganic salts are also resistant to alkali at low temperatures, but strong bases can hydrolyze them. Castor oil polyoxyethylene ether can be obtained by reacting castor oil with ethylene oxide under the catalysis of sodium hydroxide (or potassium).

2. Suitable for emulsification of various vegetable oils, mineral oils, fats, waxes, etc. It can also be used as a component of an antistatic spinning oil for synthetic fibers such as polyacrylonitrile, a component of a pesticide emulsifier, a wool conditioner “and a hair oil”.
