What is it?
After the oil is expressed from the beans, a residual castor pomace remains, which contains a potent allergen. This may be incorporated in fertilizer, which is the main source of exposure, but people who live near a castor bean-processing factory may also be sensitized.

How can I avoid it?
Skin contact with Hydrogenated Castor Oil is required for it to cause a rash. Discontinuation of exposure to products containing Hydrogenated Castor Oil should result in improvement and/or resolution of your dermatitis. By law, all products made in the US for topical use have the ingredients listed either on the product package or the box that contains it, so check the labeling of your skin care products for this ingredient. If there is no information, ask your pharmacist or call the company directly. At work, request a material safety data sheet (MSDS) to help identify potential sources of exposure.
