Product Description

Castor oil

Castor oil is a triglyceride of fatty acids. 

Castor oil exists in Castor seeds and its content is 35%~57%. 

Castor oil is prepared by squeezing or solvent extraction.

Castor oil contains 90% ricinic acid (9-olenyl-12-hydroxyoctadecanoic acid) with J hydroxyl value of 163 mg KOH/g and hydroxyl content of 4.94%, molecular weight of 929.26 based on hydroxyl. 

According to hydroxyl calculation, castor oil contains 70% tri-functionality and 30% di-functionality, and the average hydroxyl functionality is 2.7. Polyurethane adhesives made from castor oil have good low temperature properties, hydrolysis resistance and excellent electrical insulation.

Characteristic of Castor Oil

Castor oil contains a large amount of ricinic acid (more than 80%). Therefore, it has many unique properties:

1. Easy to dissolve in ethanol, difficult to dissolve in petroleum ether. The existence of this characteristic can easily distinguish castor oil from other oils.

2. Viscosity is much higher than general grease, 680 CPS at 25, viscosity index 84, friction coefficient is very low (0.1).

Castor oil has good fluidity. Refined castor oil can still flow at - 22 C and no turbidity after quenching at - 50 C. It is an ideal lubricant for aviation and high-speed machinery and a protective oil for power belts.

3. It has strong optical rotation because the asymmetric carbon atoms in ricinolic acid, its main fatty acid, are behind 12.

4. The dielectric constant is about 4.30, which is the highest in common oils.

5. The relative density and acetyl value of castor oil are higher than those of common oil.

6. Castor oil is a typical non-drying liquid oil with good storage stability and almost no oxidative rancidity in air.

Scope of application

Castor oil inducers are widely used in pharmaceuticals, cosmetics, lubricants, lubricants, metal processing oils, fiber oils, coatings, plastics, adhesives and plasticizers.
