|Tips, Tricks, and Quirks||
Sodium Lauryl Sulfate (SLS) is often confused with Sodium Laureth Sulfate (SLeS) and Sodium Lauryl Sulfoacetate (SLSa), which are both different (and milder) surfactants.
While SLS certainly can be irritating, so can many ingredients (traditional lye soap, for instance, would also be irritating to the skin if applied in high concentrations and left in contact with the skin for extended periods of time). SLS is not a carcinogen.
