Both yellow castor oil and Jamaican black castor oil are made from the castor bean, but all their differences are due to the processing method utilized. Yellow castor oil is made by pressing fresh castor beans; there is no heat involved. Thus, the term cold-pressed.
Another common use of castor oil is as an excipient, a neutral suspension used to deliver the active ingredient in drugs. A substitute for castor oil in this usage is Cremophor EL, a synthetic compound patented by the chemical company BASF SE. Cremophor EL is created by reacting 35 parts ethylene oxide with one part castor oil.
