Commercial grade castor oil is one of the standard & most common grades of castor oil, used for many industrial applications. It is also known as the industrial grade castor oil. The Commercial grade is used extensively in the manufacture of textile chemicals or as a wetting agent for inks, coatings and adhesives.
Commercial Castor Oil, obtained from the seeds of Ricinus Communis, is a pale yellow, viscous, oily liquid insoluble in water. It contains more than 87% of a unique hydroxy fatty acid viz. Ricinoleic acid.
We have Following Grade
1) Commercial grade
2) Industrial Grade
