Sodium Lauryl Sulfate (SLS) is a surfactant and a detergent. It is a cheap ingredient that is often added to bath products to produce luscious foamy lather or bubbles that last a long time. The Lauryl in SLS comes from Lauryl alcohol which can come from petroleum products, or it can also come from coconut oil. The oil is put through an elaborate process that liberates the fatty acids, hydrogenizes the oil, then pulls out the lauryl alcohol. It is still mixed with other chemicals to produce SLS, and the derivation of the lauryl alcohol from coconut oil does not make this a natural ingredient in any way. We think most would agree it probably just sounds better to be able to say the ingredient is derived from coconut oil. SLS identified as "coconut-derived" or "from coconut oil" is a marketing gimmick to make you believe the ingredients are more natural.
