Audited Supplier Product Description
It is an oil extracted by the pressing of the Castor Oil plant, Ricinus Communis. Depending on the country of cultivation, Castor Oil plants can grow between 4 feet to 40 feet tall.
The long, curved, polished leaves on purplish foot-stalks are alternatively arranged on the stem. Mature leaves are blue-green when fully expanded, and paler beneath; however, young leaves are red and shiny.
Interestingly, the Ricinus Communis has both a male and female flower, with the male growing on the under portion of the spike and the female growing on the upper portion.
The blunt, greenish, deeply-grooved capsule-like fruit of the Castor Oil plant is less than one inch long and produces compressed oval seeds, which are pressed to obtain Castor Oil.

Function
Castor oil is a triglyceride of fatty acids, castor oil exists in the seeds of castor oil, the content of which is 35% ~ 57.% "castor oil was extracted by extraction or solvent extraction method. Ricinoleic acid contains 90% ricinoleic acid (9 monotony 1 12· hydroxyl octadecanoic acid).
The hydroxyl value is 163mgKOH/g, the hydroxyl content is 4.94%, the molecular weight of hydroxyl is 929.26, according to the hydroxyl calculation, ricinoleic oil contains 70% of the trifunctional degree and 30% of the difunctional degree, the average hydroxyl functional degree is 2.7.
Polyurethane adhesive made from castor oil has good low-temperature property, hydrolysis resistance, and excellent electrical insulation.
