Disinfectant

Abstract

The disinfectant capable of realizing effective sterilization by using a surfactant contains water, from which polyvalent cations are removed and to which a sodium ion is added, and a surfactant. An example of the surfactant is a fatty acid salt. When the disinfectant is applied to an object to be treated, fungi and bacteria adhering thereto are sterilized by the action of the surfactant. The surfactant contained in the disinfectant hardly remains on the object owing to the effect of the water from which polyvalent cations are removed and to which a sodium ion is added, and then is not likely to be a source of nutrient for fungi and bacteria. Accordingly, on the object to which the disinfectant is applied, fungi and bacteria are sterilized and propagation thereof is suppressed, and thus a hygienic state of the object is easily maintained. The disinfectant is particularly effective when it is used for, for example, bathrooms, tabs of washing machines, kitchens, toilets, washstands, drainpipes and daily commodities.
