摘要：

Provided is a method for producing a one-liquid stabilized hypobromous acid composition which contains substantially no bromate ions, has excellent sterilization performance, exhibits almost no corrosiveness relative to metals, and displays excellent storage stability. This method for producing the stabilized hypobromous acid composition includes a step in which a reaction is induced by adding, under an inert gas atmosphere, bromine to a mixed solution including water, an alkali hydroxide, and sulfamic acid, wherein the proportion of bromine added is not more than 25 wt % relative to the total weight of the composition.
