An inexpensive and very effective foamer with much less irritation than Sodium Lauryl Sulphate. Derived from coconut, it's found in many personal care products like soaps, shampoos, toothpaste etc. Cancer concerns around many anionic surfactants by a supposed ‘medical study’ does not exist, and both the FDA and Health Canada have determined that both SLS and SLES are completely safe. Studies show when continuously applied to the skin in full strength without washing, these compounds become irritants, not carcinogens. For more information, just Google ‘hoax, sodium lauryl sulphate’.
