Abstract: A concentrated antiseptic cleanser composition for use on an industrial scale is disclosed, comprising effective amounts of iodine as the antiseptic agent and an organic detergent (preferably sodium lauryl sulfonate) as the cleansing agent, an alcoholic solvent, preferably iso-propanol, a buffer, preferably sodium borate decahydrate, and a chelating agent preferably tetrasodium EDTA. A mild abrasive cleansing agent and a fragrant also may be present. Water is present in an inverse relationship on a volume percent basis with the lower alcohol solvent. The pH of the composition ranges from about 7.9 to 8.5. This concentrated composition demonstrates superior antiseptic and cleansing properties, and is useful on a wide variety of surfaces, most commonly used in public restrooms and the like.
