PROBLEM TO BE SOLVED: To obtain a bactericidal detergent which is excellent in bactericidal and cleaning effects and in safeness by incorporating bile acid, an organic acid, and an alcohol into the same. SOLUTION: Bile acid used maybe in the form of a bile powder, a crude product, separated from bile, etc., of cattle or pigs or may be a high-purity one obtained by purifying a crude product. Cholic acid and deoxycholic acid separated from bile acid may be used in place of bile acid. The concentration of bile acid in the detergent is 0.05-5 wt.%. Though the organic acid may be arbitrarily selected, a 2-6C mono- or polycarboxylic acid is preferably used, such as acetic, citric, or lactic acid. The cocentration of the organic acid in the detergent is 0.05-4 wt.%. The alcohol is a 2-6C monoalcohol, preferably ethanol, and its concentration in the detergent is 10-30 wt.%. When used, the detergent generally has a pH of 3-5.5. A natural-derived acid (e.g. citric acid) or its salt, carbonate, or phosphate is used as an adjusting agent. |
