  Not a significant amount. The way SLS works it just does not form insoluble salts the same way soap does. The SLS micelles are just much more stable.

  @Perry44 this data shows in hard water, more SLS was attached to skin compared to soft water. Does it mean even those soluble molecules from interaction of SLS and calcium can stay on skin or hair and cause problems?
