What is it?
Amidoamine is a manufacturing byproduct of the soap-like chemical, Cocamidopropyl Betaine.
How do I avoid it?
Since Cocamidopropyl betaine is widely used, its chemical byproduct, Amidoamine, may be difficult to avoid. It is
found in over 600 personal care products. It is primarily found in shampoos and bath gels, but is also used in some
bar soaps, liquid detergents, surface cleaners, pet car products, and other skin and hair care products. It typically
presents as eyelie, facial, scalp and/or neck dermatitis.
You need to look at the ingredient list of the products (soaps, shampoos, etc.) you are putting on your skin and make
sure they don’t contain the following chemicals: Amidoamine and Cocamidopropyl Betaine.
Skin contact with Amidoamine is required for it to cause a rash. Discontinuation of exposure to products containing
Amidoamine 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.
