#1 Castor Oil

Chemical Name: Castor Oil

CAS#: 8001-79-4

  • Product Details & Information

    Castor Oil is one of the oldest and most versatile products in use today. In fact, according to Wikipedia, it has been found in Egyptian tombs over 4,000 years old. There are other documented uses in China and India, also dating back thousands of years. In the Netherlands, it was called “Wonder Oil” and was thought to be a cure for a multitude of ailments. It is a natural product, made from the beans of the castor plant which can be grown in any tropical region. India is the world’s largest producer of Castor Oil (over 80%), with China and Brazil being a far-distant second and third place.

    Although Castor Oil still has medicinal uses today, it has many more applications as a cosmetic ingredient, an industrial chemical and a specialty chemical. As a natural polyol, it is commanding increasing attention as a highly effective ingredient in polyurethane applications, replacing the traditional petroleum based polyols. Another advantage of Castor Oil is that it is not a food oil, meaning it is not subject to the controversies that can arise with other oils.
