Castor oil is a vegetable oil derived from the seeds of the castor bean plant, scientifically known as Ricinus communis. It is known for its thick consistency and pale yellow color. The oil is rich in ricinoleic acid, which gives it unique properties, making it popular in various applications, including cosmetics, pharmaceuticals, and as a laxative. In addition to its medicinal uses, castor oil is often used in the production of soaps, lubricants, and biodiesel. Its moisturizing properties make it a common ingredient in skin and hair care products, where it helps to hydrate and nourish.
