1. An unbuffered detergent composition that is environmentally friendly for cleaning a surface of urushiol, wherein the unbuffered detergent composition comprises:
water in an amount of from 40 to 60 weight percent of the unbuffered detergent composition; surfactants, wherein the surfactants consist of a sodium lauroyl sarcosinate, a sorbitan monolaurate, and a non-ionic polyethylene glycol ether of a mixture of synthetic C12-15 fatty alcohols with an average of 9 moles of ethylene oxide;
at least one type of bio-degradable bead having a maximum particle size of 300 microns;
wherein the unbuffered detergent composition is free of any ethoxylate that is not part of the nonionic polyethylene glycol ether of a mixture of synthetic C12-C15 fatty alcohols with an average of 9 moles of ethylene oxide;
wherein the unbuffered detergent composition is free of any of the following: (1) any nonylphenol ethoxylate, (2) any pharmaceutically active drug or prodrug, (3) any salt in granular form; and (4) any ethoxylate that is a stand-alone ingredient; and
wherein the unbuffered detergent composition completely biodegrades in an ambient environment after 2 years.
