Patent ID: 7229612

Claim:
Aqueous deodorizing composition for human and animal excrement, consisting essentially of tap water; an acid agent in an amount sufficient to neutralize ammonia and indolic amines in said excrement wherein the acid agent comprises at least one biodegradable carboxylic acid, whereby said composition is biodegradable; and at least 0.1% of at least one biologically degradable non-toxic and ecologically safe water soluble polymer, said polymer being present in an amount sufficient for forming, upon drying, a thin film vapor barrier on the excrement in a concentration range of 0.1% to 10% w/v; wherein the water soluble polymer is a barrier forming agent for the vapor of offensive odor producing compounds in the excrement and is selected from the group consisting of hydroxyethyl cellulose, polyethylene oxide, polyvinyl pyrrolidone, polyhydroxyethyl (meth) acrylate, polyvinyl alcohol, and polyhydroxypropyl methacrylate, and wherein the water soluble polymer has a molecular weight of higher than 15,000, and, when formed as a film over said excrement will eventually biodegrade.
