Butyl acetyl ricinoleate, more commonly known as castor oil ester, is a natural ester derived from castor oil. It is used in the production of a variety of products, including lubricants, cosmetics, and pharmaceuticals. When exposed to rubber, butyl acetyl ricinoleate can cause swelling and cracking due to its high solubility in certain rubber compounds. It can also cause the rubber to become brittle and more susceptible to cracking or tearing. To prevent these types of failures, it is important to select a rubber material that is appropriate for the environment, as well as to take steps to limit the amount of exposure to the chemical.
