Is sodium lauryl sulfate bad or not? It's in all shampoos that foam....
"Incidentally, regarding sodium lauryl sulfate, that is an internet hoax. It can be irritating to the skin in some formulations for some people, however it DOES NOT CAUSE CANCER. There has been a lot of effort to debunk this myth, including this statement from the Toxicology journal in question:
The american cancer society and the canadian health department have both put out disclaimers regarding this internet hoax and the scientist who wrote the mis-quoted paper from the University of Georgia Medical School has expressed his embarrassment over the entire thing. He himself stated that he never did any more research on (after the early 1980s) it because it proved to be so safe!
