A Few Facts About SLS
Did you know that Sodium Lauryl Sulfate (SLS) is a surfactant, detergent and emulsifier used in thousands of cosmetic products, as well as in industrial cleaners. It is present in nearly all shampoos, scalp treatments, hair color and bleaching agents, toothpastes, body washes and cleansers, make-up foundations, liquid hand soaps, laundry detergents and bath oils/bath salts.
Although SLS originates from coconuts, the chemical is anything but natural.
The real problem with SLES/SLS is that the manufacturing process (ethoxylation) results in SLES/SLS being contaminated with 1,4 dioxane, a carcinogenic by-product. According to the Environmental Working Group's Skin Deep: Cosmetic Safety Reviews, research studies on SLS have shown links to:
- Irritation of the skin and eyes
- Organ toxicity
- Developmental/reproductive toxicity
- Neurotoxicity, endocrine disruption, ecotoxicology, and biochemical or cellular changes
- Possible mutations and cancer
If you visit the SLS page on the Environmental Working Group's (EWG) website, you will see a very long list of health concerns and associated research studies. In fact, you will also see their mention of nearly 16,000 studies in the PubMed science library (as well as their link to that list) about the toxicity of this chemical.
