Sodium Lauryl Sulfate (SLS) is a detergent and foaming agent. It’s also in the same family as Sodium Laureth Sulfate (Surfactants). Both are common in soaps, shampoos, toothpaste and skincare products.

SLS is a known skin irritant. In higher concentrations it’s an effective engine degreaser, commercial floor cleaner and car wash detergent – harsh stuff.

According to the cosmetic trade industry association, sulfates, like Sodium Lauryl Sulfate, “appear to be safe in formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin.”

Have you ever accidentally got shampoo in your eyes? The irritation you experienced is due to SLS.

There have been conflicting studies over the decades but it’s generally accepted SLS isn’t cancer causing. However, just because something doesn’t cause cancer doesn’t make it entirely safe either.

ExPürtise recommends staying away from Sodium Lauryl Sulfate whenever possible. While SLS is present in many consumer products, we feel the skin on your face should be pampered. Find different ways to cleanse your skin. The thought of cleaning our faces with engine degreaser seems a little extreme. That’s why all ExPürtise products are formulated Sodium Lauryl Sulfate free.
