TECHNICAL FIELD The present invention relates to an oxygen-based bleaching composition suitable for removing mold on hard surfaces.

[0002]

2. Description of the Related Art Dirt in areas such as bathrooms, bathtubs, toilets, and sinks where water is frequently used is often caused by mold and the adherence of colored substances by mold, and hygiene management of users and maintenance of houses. Therefore, it is not preferable.
By the way, it is difficult to remove these adhering substances by washing once generated and adhering. Conventionally, washing with a detergent having a surfactant as a main component has been performed for removing these substances.
Not enough results have been obtained. Although the use of a bleaching agent centered on sodium hypochlorite as a chlorine-based bleaching agent is certainly effective in removing stains, the bleaching agent accidentally adheres to the eyes and skin during its use, resulting in damage accidents. It is necessary to take measures to prevent this from occurring, and chlorine is generated during use, so sufficient ventilation is also necessary. There is also an accident that the user mistakenly uses an acidic cleaner together with insufficient ventilation, and there is an accident due to the generation of harmful chlorine.Chlorine bleach must be used according to the prescribed method. The problem is that there is still some uneasiness in handling. As the oxygen-based bleaching agent, a bleaching agent mainly containing hydrogen peroxide has been used. It does not have to be used under severe conditions of use like chlorine bleaches, but the bleaching effect is not sufficient compared to chlorine bleaches. Therefore, it has been proposed to use various compounds in combination (for example, JP-A-60-1299).
JP-A No. 62-4794, JP-A No. 2-19
896, JP-A-3-121200, etc.).
In these publications, it is described that it is effective to use, as these compounds, those that utilize the production of peracetic acid, but the effect is not sufficient, and there is a pungent odor peculiar to peracetic acid. , Was not worth using. Since then, the development of a compound to be used in combination with hydrogen peroxide has been advanced, and recently, it has been found that a monomethyl monocholine ester of terephthalic acid is effective as a bleaching activator to be used in combination with an oxygen bleach. 7-196887).
Also, the aqueous solution containing hydrogen peroxide undergoes decomposition during storage,
Problems such as the effect being halved within the usage period were pointed out,
There is also a great demand for improving the stability of the oxygen-based bleaching agent as a composition.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an oxygen-based bleaching composition which is excellent in bleaching and removal of colored substances caused by mold and mold attached to a hard surface, has no irritating odor when used, and is stable when stored.
