The chemical, cocamide diethanolamine, is a chemically modified form of coconut oil. It is used as a thickening or foaming agent in products like shampoo, liquid soaps, body wash and bubble bath, but was banned last year after a study found it caused cancer in laboratory animals.
Manufacturers are required to put a warning on the label on products containing this chemical. The Center for Environmental Health filed suit after discovering the presence of cocamide DEA.
Some of the products that contain high levels of the illegal chemical are sold under well-known companies such as Colgate Palmolive, Paul Mitchell, and Prell. Lab tests also found the carcinogen in children’s products, such as a store brand bubble bath from KMart, and a shampoo/conditioner from Babies R Us. Other store brand products that contain the carcinogen came from Trader Joe’s, Walmart, and Kohl’s.
