Polyoxyethylene castor oil CAS 61791-12-6

Polyoxyerays castor oil is a yellow viscous liquid resistant to hard water, acids, alkali, and inorganic salts. Used for emulsifying and dissolving oil and other water-insoluble substances. Active matter content: >=99

About Polyoxyethylene castor oil :

According to the number of EO, Polyoxyethylene castor oil can be divided into EL-10, EL-20, (H)EL-40, EL-60, el-80, etc. With the increase of EO number, water solubility increased and HLB value increased. It has good emulsifying properties.

is a trusted global Polyoxyethylene castor oil. Feel free to send an inquiry to get the latest price of Polyoxyethylene castor oil if you would like to buy Polyoxyethylene castor oil in bulk.

Production methods of Polyoxyethylene castor oil :

Add 1 mol of castor oil into the reactor, and then add solid potassium hydroxide equivalent to 0.3% of castor oil to stir. Heat up until KOH dissolves, then replace the air in the reactor with N2, and inject ethylene oxide into the reactor. The reaction temperature is maintained at 160~180, and the pressure is 0.15~0.2 MPa. For cooling, the material is moved into the bleaching kettle, and the pH is adjusted to slightly acidic with acetic acid, and 0.1% hydrogen peroxide is added for decolorization. After 70 times of heat preservation, 0.5h is maintained for 5 h, and the material is cooled for 5 h by decompression dehydration.

Applications of Polyoxyethylene castor oil :

L-20 and HEL-20 can be used as spinning oils of acrylic fiber, etc., and can also be used as weaving oils to make sizing soft and smooth, and easy to weave. They can also be used as emulsifiers, diffusers, and wetting agents. And HEL-20 has the characteristics of low coking at high temperatures. El-40 is an oil-in-water emulsifier, which is used as wool oil in the wool textile industry. It has good antistatic properties and is better combined with other antistatic agents. It can be used as an emulsifier in pharmaceutical, pesticide, and other industries. El-80 can be used as a component of acrylic fiber, PVA fiber, polypropylene fiber, and other chemical fiber oil agents, with antistatic and emulsifying effects, and can be used as an emulsifier of organophosphorus pesticide dioxin, emulsion polymerization emulsifier, and emulsifier of wool oil. Widely used in textile printing, dyeing, paint, ink, and other industries, but also used as a variety of oil emulsifier
