You probably thought that the worst thing your shampoo could do to you is to burn your eyes, but it turns out that your shampoo could be deadly. The Center for Environmental Health based in Oakland, California, performed a study on shampoos and soaps and found that 98 included a possible carcinogen known as cocamide diethanolamine (cocamide DEA).
Cocamide Diethanolamine (cocamide DEA), a controversial ingredient found in body care items, has landed four personal care manufacturers with a lawsuit in California.
The Center for Environmental Health filed the suit after discovering the presence of cocamide DEA, the foam stabilizer and volumizer, in shampoos and soaps. In the state of California, Proposition 65 requires manufacturers to warn consumers over the risks of certain substances. Cocamide DEA is on that list because it is a suspected carcinogen. It was banned in the state last year after a study found it caused cancer in laboratory animals.
