Polyoxyethylene castor oil CAS 61791-12-6 |

Polyoxyethylene Castor Oil can be divided based on the number of EO into EL-10, EL-20, (H)EL-40, EL-60, el 80, etc. Water solubility and HLB value increase with increasing EO numbers. It has excellent emulsifying qualities.

Stir solid potassium chloride equal to 0.3% castor oils into the reactor. Heat until KOH is dissolved, replace air in reactor with N2, then inject ethyleneoxide into reactor. The reaction temperature should be maintained between 160180 and the pressure at 0.150.2MPa. To cool the material, it is transferred into the bleaching tank, the pH of which is slightly acidic is adjusted with acetic, and 0.1% peroxide added to decolorize. After 70 cycles of heat preservation, the temperature is kept at 0.5h for 5h and then the material is cooled using decompression.

L-20 and HEL-20 may be used for acrylic fiber spinning, as well as as weaving oils. This will make the sizing easy to work with, as it is soft, smooth and easy to weave. Also, they can be used as diffusers and wetting agent. HEL-20 also has low coking characteristics at high temperature. El-40, an oil-in water emulsifier is used to make wool oil for the textile industry. It has excellent antistatic properties, and it is best combined with other agents that are antistatic. It can be used to emulsify in pesticide, pharmaceutical and other industries. El-80 has antistatic and emulsifying properties and can be added to acrylic fiber, PVA, polypropylene, and other chemical fibre oil agents. It can also be used to emulsify organophosphorus dioxin pesticide, emulsions polymerization, and wool oils. It is widely used in textile dyeing, printing, paint, ink and other industries. But it can also be used to emulsify a variety oil.
