Abstract

                                Castor bean has been an important item of commerce since olden times. For many centuries the oil has been used in medicine, in printing, dyeing and machine lubrication. Chemists have found new uses for castor oil and its derivatives. The products are in extensive use for the manufacture of paints, plastics, rayon, textiles, nylon, special lubricants, transparent soap manufacture and many other special items. Great strides have been made in this direction in other countries, but India is only making a beginning in this respect.
