Castor oil and its derivatives are mostly used in the manufacturing of lubricants, soaps, hydraulic and brake fluids, dyes, coatings, paints, inks, cold resistant plastics, waxes, polishes, nylon, pharmaceuticals and perfumes. Mineral oil has many uses in the fields of Biomedicine, Food Preparation, Mechanical, Electrical, and Industrial capacities. The most common usage of mineral oil is a base in several cosmetic products. Castor oil contains fatty acids named omega-3s. The omega-3 fatty acids are beneficial to heal wounds and reduce collagen deposition by helping the body to minimize the formation of scarring.
