1. A urushiol cleaning composition for removal of urushiol off a surface of human skin comprising:
a non-buffered detergent composition that comprises a first solely C12 surfactant, a second solely C12 surfactant, and a non-ionic polyethylene glycol ether of a mixture of synthetic C12-C15 fatty alcohols with an average of 9 moles of ethylene oxide; and
wherein the non-buffered detergent composition is free of each of the following: (1) any nonylphenol ethoxylate, (2) any pharmaceutically active drug or prodrug, (3) any salt that affects the functional characteristics of either of the solely C12 surfactants, (4) any salt in granular form, and (5) any ethoxylate added as a separate component and not part of the non-ionic polyethylene glycol ether of a mixture of synthetic C12-C15 fatty alcohols with an average of 9 moles of ethylene oxide; and
wherein the first solely C12 surfactant and second solely C12 surfactant are present in a ratio based on the percent of active ingredient in the non-buffered detergent composition in a ratio range of from 1 part first solely C12 surfactant to up to 2.5 parts second solely C12 surfactant.
