B.S.S. Castor Oil/F.S.G. Castor Oil is Castor Oil bleached to British Standard Specifications. It is a yellow viscous liquid free from suspended matter and insoluble in water. First Special Grade Castor Oil is produced by refining commercial grade Castor Oil by undergoing bleaching and filtering process. Bleaching is done using bleaching earth and activated carbon, which helps to reduce color and Moisture content. First Special Grade (B.S.S) Castor Oil is a triglyceride ester of fatty acids, a major constituent being 12-Hydroxy Oleic Acid ( min 82% ). It is suitable for its hydroxyl functional groups in various chemical derivatization processes used in the manufacture of medicinal intermediates & lubricants etc.
