Abstract
Abstract A method of deodorizing diapers and human excreta is provided which comprises applying to the diapers or the excreta a chemical composition which in its simpliest form consists of an acidic material, an antibiotic material, and a solvent. The impregnating composition may also contain a chelating agent and a wetting agent. The exact nature of the acids, antibacterial agents, solvents, chelating agents, and wetting agents is described. The treatment of diapers results in a marked decrease in offensive odors from excreta, thus making the changing of sorted diapers less unpleasant.
