1. A method for producing a stabilized hypobromous acid composition, the method comprising:
inducing a reaction by adding bromine, under an inert gas atmosphere obtained by replacing air inside a reaction vessel with an inert gas, to a mixed solution comprising water, an alkali hydroxide and sulfamic acid, wherein
a proportion of bromine added is not more than 25 wt % relative to a total weight of the stabilized hypobromous acid composition.
