Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bleaching detergent composition.

[0002]

2. Description of the Related Art Since spots of spills and yellowing of underwear are stains that cannot be completely removed with a normal detergent, bleaching agents are generally used together with such detergents.
Methods such as using a detergent containing a bleaching agent are employed. Also, a bleach activator is used in combination for the purpose of enhancing the effect of the bleaching agent.

The present inventors have disclosed in JP-A-64-68747 that a bleach activator having a quaternary ammonium group and a nitrile group has a high bleaching effect. JP-A-4-253947 discloses a bleaching activator having a quaternary ammonium group and a nitrile group with an organic anion as a counter ion.

On the other hand, the bleaching effect of the bleaching activator greatly affects the bleaching effect due to the affinity between the structure of the organic peracid generated in the washing bath and the stains of interest, for example, lipophilic stains such as yellowish stains. On the other hand, it is known that a bleach activator which produces an organic peracid having a lipophilic group is effective. However, when this finding is applied to the above-mentioned nitrile-type bleach activator, it has a high bleaching effect, but there is a problem that so-called re-contamination occurs in which stains once detached are re-attached to clothing, and this improvement is required.

Accordingly, an object of the present invention is to provide a bleaching detergent composition which has a high bleaching effect and suppresses recontamination.
