Refined or unrefined? | Sodium Lauryl Sulfate (SLS) only exists as a refined product |

Alternatives & Substitutions | Would choose something milder, like Sodium Coco Sulfate (SCS), Sodium Laureth Sulfate (SLeS), or Sodium Lauryl Sulfoacetate (SLSa). |
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. |
