2. Description of the Related Art Bleaching agents are classified into chlorine bleaching agents and oxygen bleaching agents. Oxygen bleaching agents have the characteristic that they can be used for colors and patterns, and are becoming the mainstream bleaching agents for clothing. . The oxygen-based bleaches are classified into powder type and liquid type, each having its own characteristics. Liquid-type products have been recognized for their ease of use and have come to be widely used, and have become the mainstream of bleaching agents for clothing. The main bleaching base of this oxygen bleach is hydrogen peroxide, but its bleaching power is inferior to that of chlorine bleach, and its improvement has been a problem.

[0003] Regarding the improvement of the bleaching power of oxygen-based bleach,
Much research has been done. One approach is to use an organic peracid precursor. The organic peracid precursor reacts with hydrogen peroxide in the cleaning solution to produce an organic peracid having higher bleaching power. It is a mechanism that strongly decomposes stains by the organic peracid generated here. As the peroxide that generates hydrogen peroxide in the cleaning liquid used here, powder type bleach, or in heavy detergents having bleaching performance, sodium percarbonate and sodium perborate are widely used, and liquid Hydrogen peroxide is mainly used as a bleaching agent. In addition, the organic peracid precursor includes:
For example, tetraacetylethylenediamine (TAED),
Glycos pentaacetate (PAG) and phenol derivative alkyl esters can be mentioned.

[0004] Another problem is the stabilization of hydrogen peroxide. When hydrogen peroxide is alkaline, it usually decomposes itself to generate oxygen gas. Therefore, the liquid oxygen bleach currently on the market is adjusted to be acidic. However, the bleaching effect of hydrogen peroxide is higher under alkaline conditions than under acidic conditions, so that it is generally used in combination with a detergent. That is, another problem is to exert a high bleaching effect even when used alone. For that purpose, it is necessary to stabilize hydrogen peroxide at a higher pH so that it can be safely marketed as a product.

As described above, the liquid bleaching composition of the present invention has excellent bleaching power due to the above constitution, and is generated by decomposition of hydrogen peroxide even when stored at a relatively high pH for a long period of time. The amount of generated gas is small (excellent in storage stability). In addition, since it is excellent in storage stability, even if it is filled in an inexpensive container made of plastic or the like having no gas leakage mechanism, there is no fear of swelling or breakage of the container, and it is also economical.
