Castor Oil is a vegetable oil that contains ricinoleic acid, which is more polar than other fatty acids, and makes castor oil thick and sticky. Castor oil is used for haircare and helps in deep conditioning and thickening the hair and making it more beautiful and shinier. The ricinoleic acid helps balance the scalp’s pH level and reduces the risk of dandruff, split ends, and hair breakage. Applications include formulations for soaps, paints, dyes, waxes, nylon, pharmaceuticals and perfumes.
