Description of the Related Art An aqueous hydrogen peroxide solution tends to decompose into water and oxygen, and is difficult to maintain for a long period of time unless an appropriate stabilizing method is used. This decomposition depends on various factors, such as temperature, pH, and the presence of transition metal ions that act as active catalysts. Therefore, the decomposition can be reduced by adding an appropriate metal complexing agent as one of the principle methods of stabilization, and a stabilizer comprising many complexing agents has been proposed and used. However, aqueous hydrogen peroxide is relatively easy to stabilize under acidic conditions, but it is difficult to sufficiently stabilize it under alkaline conditions, and it has been considered that it is practically impossible. On the other hand, aqueous hydrogen peroxide has an excellent bleaching effect under alkaline conditions, and must be used under alkaline conditions in order to exhibit an effective bleaching effect. Therefore, conventionally, when an aqueous solution of hydrogen peroxide stabilized by acidity is used, a method of using the aqueous solution in combination with an alkali agent and making it alkaline has been adopted.

物の析出や毒性上の問題から使用し難い。As described above, in order to perform an effective bleaching effect with aqueous hydrogen peroxide, it is necessary to make the solution alkaline, and the higher the pH of the solution, the higher the bleaching effect. Stabilizers for stabilizing an aqueous solution of hydrogen peroxide under alkaline conditions include, for example, tin compounds typified by sodium stannate, and 1-hydroxy-1,1- An acetophosphonate represented by diphosphonic acid or an aminomethylene phosphonate represented by diethylenetriaminepenta (sodium methylene phosphonate) has been proposed (JP-B-37-7303, JP-B-59-45601, European Patent No. 0376704). Among these known stabilizers, the acetophosphonate of a phosphorus compound, which has a simple structure and is relatively easy to produce, has not yet been able to say that its stabilizing effect is still sufficient, and it can be stored for a long time under alkaline conditions. Then, problems such as a decrease in effectiveness due to decomposition of hydrogen peroxide and swelling of the container are observed. In addition, aminomethylene phosphonate has a complicated structure, while tin compounds are difficult to use because of precipitation of precipitates during storage and toxicity problems.
