Abstract
A composition and method for delivering sulfur to skin and absorbing irritants in the skin. A high sorption base is employed which comprises non-swelling clay, gum, swelling clay, silicon and combinations thereof. The absorption of the irritants does not hinder the delivery of the active ingredient to the skin.
