Organic Castor Oil The pressing of the castor bean Ricinus communis results in Castor Oil, which is a universal light pale-yellowish oil used widely for applications ranging from cosmetic to industrial. No solvents were used in the production. When making our selection of which Castor Oil to offer we didn't choose the least expensive, we picked the highest quality and we think you will agree that this is the best quality on the market. Please note: Dropper sold separately.
