I've been doing some Googling on this stuff, and the results are somewhat scary,

Studies on SLS have shown that:" (Judi Vance, Beauty To Die For, Promotion Publishing, 1998)
"Shampoos with SLS could retard healing and keep children's eyes from developing properly. Children under six years old are especially vulnerable to improper eye development. (Summary of Report of Research to Prevent Blindness, Inc. conference."
"Sodium Lauryl Sulphate can cause cataracts in adults and delays the healing of wounds in the surface of the cornea."
"Sodium Lauryl Sulphate has a low molecular weight and so is easily absorbed by the body. It builds up in the heart, liver and brain and can cause major problems in these areas."
"Sodium Lauryl Sulphate causes skin to flake and to separate and causes roughness on the skin."
"Sodium Lauryl Sulphate causes dysfunction of the biological systems of the skin."
"Sodium Lauryl Sulphate is such a caustic cleanser that it actually corrodes the hair follicle and impairs the ability to grow hair."
"Sodium Lauryl Sulphate is routinely used in clinical studies deliberately to irritate the skin so that the effects of other substances can be tested." (Study cited by the Wall St Journal, 1st November 1998)
None of that sounds good. Anyone have any comments?
