DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oxygen-based tablet-type mold-removing composition having no forming harmful gas during use and having no irritating odor, suitable for mold-removing, and having good forming strength. About.

[0002]

2. Description of the Related Art Bathrooms, bathtubs, toilets around houses,
Stain, such as sinks, especially where water is used frequently, is often due to organic or insoluble inorganic substances caused by mold,
Since ordinary detergents containing surfactants as the main component cannot be easily removed, to remove these stains, use a chlorine- or oxygen-based bleaching agent as the main component, and bleach it. A method has been adopted in which the effect makes the color of the mold inconspicuous.

[0003] However, those containing a chlorine bleach such as sodium hypochlorite as a main component are excellent in the bleaching power of mold dye and the performance of removing mold, but have a great risk of damaging eyes and skin. In addition, when using a chlorine odor strongly, it is necessary to pay attention to sufficient ventilation, and there is a drawback that harmful chlorine gas is generated when used in combination with an acidic cleaning agent by mistake.

[0004] On the other hand, those containing an oxygen-based bleaching agent represented by hydrogen peroxide as a main component do not have a drawback of generating chlorine gas, but can provide a sufficient bleaching effect of a mold dye by themselves. Therefore, various bleach activators had to be used in combination (for example, see JP-A-2-225).
No. 600, JP-A-2-196896, JP-A-62-4
No. 794).

However, even if these organic peracid bleach activators are used in combination, the bleaching effect on mold dyes is only slightly improved, and the removal of mold by itself is still insufficient. There is a drawback that dirt easily adheres.

[0006] In addition, to prevent the occurrence of dust when adding a granular detergent, attempts have been made to develop tablet detergents, which dissolve in a high-temperature aqueous solution.
Since it does not readily dissolve in water at normal temperature, there is a problem that the nozzle portion is clogged when spraying using a dispenser type container or the like.

[0007]
