Yeah, I got the idea for this thread subject from the cancer causes thread.

I felt that this subject deserves its own thread.
I've also noticed products claiming no SLS.
When I was 19 (12 years ago) I was working at a local Health Food store. In my free time, I would pick a book from the shelves and read some of it. One of the books was focused on common cancer agents. It listed many chemicals that are commonly used in both food and cosmetic items. For some reason, SLS stuck with me. The book (wish I could remember the title) made it out to be the worst chemical that people are regularly exposed to. For a few years after, I avoided it like the plague, carefully reading every label to make sure that the product did not contain SLS.
Then, one day while researching, I found other claims that suggested no ill effects from SLS. Ever since then, I've taken the default position of skepticism. I'm hoping that someone knows of some recent research that can lay these claims to rest, one way or another.
