jux find out that SLS contain carcinogen is myth!!!!!!!!!

Questions and answers:
Is sodium laureth sulfate commonly found in shampoos and toothpastes?
A: Shampoos, yes;toothpastes, no.

Q: Is sodium laureth sulfate known to cause cancer?
A: No. The chemical does not appear on any official list of known or suspected carcinogens.

Q: Is sodium laureth sulfate properly abbreviated as "SLS?"
A: No. The correct abbreviation is "SLES." The chain letter confuses this compound with another: sodium lauryl sulfate, which is abbreviated "SLS." The two substances are related, but not the same.

Q: Is sodium laureth sulfate used to scrub garage floors?
A: No.

Q: What about the other one - sodium lauryl sulfate - is it used to scrub garage floors?
A: No doubt! SLS is a powerful surfactant (wetting agent) and detergent. It has industrial uses, but is also commonly found in lesser concentrations in shampoos, toothpastes, shaving creams, etc.

Q: Ah. Well, then, is SLS a known carcinogen?
A: No. But it's not as harmless as SLES. Sodium lauryl sulfate is a skin and eye irritant and can cause dermatitis with prolonged contact. Results of some tests on animal tissues indicate that it can cause abnormal cell mutations, though I've seen conflicting evidence.

Q: Would a manufacturer freely admit to consumers, as claimed in the message, that it knowingly uses a carcinogen in its products "because we need that substance to produce foam?"
A: Are you kidding? Of course not!
