Refined castor oil/b.s.s. /f.s.g.: crude castor oil is pale straw in colour but turns colourless or slightly yellowish after refining and bleaching in the presences of activated carbon and bleaching earth. bleaching material is removed by filtration of refined castor oil.
Castor oil is unique among all fats and oils in that:
•it is the only source of an 18-carbon hydroxylated fatty acid with one double bond
•ricinoleic acid (12-hydroxyoleic acid) comprises approximately 90% of the fatty acid composition
•product uniformity and consistency are relatively high for a naturally occurring material
•it is a nontoxic, biodegradable, renewable resource.
We are offered in the form of highly viscous yellowish liquid
castor oil: available yellowish liquid
