Abstract: A method for measuring only a concentration of a peroxycarboxylic acid in an equilibrium mixture containing peroxycarboxylic acid and hydrogen peroxide, comprising the following steps a) and b); a) adding potassium iodide to the equilibrium mixture to cause the generation of iodine and providing the resulting mixture as a measurement sample; and b) measuring the amount of light that goes through the measurement sample to determine only the concentration of a peroxycarboxylic acid.

Abstract: The objective of the present invention is to provide a biodegradable low-foaming detergent composition having a high washing power across a wide temperature range. A biodegradable low-foaming detergent composition, which comprises a sophorolipid, is provided. The sophorolipid includes a sophorolipid (lactone type) at the ratio of at least 35%. Preferably, the sophorolipid includes a sophorolipid (lactone type) and a sophorolipid (acid type) at a ratio of 35:65 to 90:10. The composition may further comprise a detergent auxiliary component. The detergent auxiliary component is selected from the group consisting of enzyme, oxygen bleaching agent, bleaching activator, alkaline builder, sequestering agent (Ca scavenger), fluid reforming agent, and a neutral inorganic salt.

Abstract: A disinfectant composition for medical use is provided that has satisfactory bactericidal effects, and that rarely causes skin damage even when used frequently. The composition comprises ethanol used for disinfection, a bactericidal agent, and an emollient, wherein said bactericidal agent is at least one selected from the group consisting of chlorhexidine digluconate, alkylpyridinium salts, and quaternary ammonium salts, and said emollient is at least one selected from the group consisting of diesters of dibasic acid, triesters of citric acid, triesters of phosphoric acid, polyoxyethylene glyceride of higher fatty acid, and polyglycerol.
