Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid bleaching composition, and more specifically, a liquid containing a bleaching activator which reacts with hydrogen peroxide and has an excellent storage stability to produce an organic peracid. Bleach composition.

[0002]

BACKGROUND OF THE INVENTION Bleaching agents are classified into chlorine-based bleaching agents and oxygen-based bleaching agents, but chlorine-based bleaching agents are limited in the fibers that can be used, and cannot be used in colors and patterns. Oxygen-based bleaching agents, which do not have these drawbacks, have recently become extremely popular due to their unique and unique odor.
Among the oxygen-based bleaching agents, sodium percarbonate and sodium perborate are used as powder bleaching agents, and hydrogen peroxide is used as a liquid bleaching agent.

However, these oxygen-based bleaching agents have a weaker bleaching power than chlorine-based bleaching agents, and various bleaching activators are used together. Examples of these bleach activators include O-, which is represented by glucose pentaacetate (GPAC) and the like.
Examples thereof include acetylated products, N-acylated products represented by tetraacetylethylenediamine, and acid anhydrides represented by maleic anhydride. Furthermore, the inventors of the present invention have disclosed JP-A-63-233969, JP-A-63-31566, and JP-A-63-31566.
As disclosed in JP-A 64-68347 and JP-A-1-190654, a compound which reacts with hydrogen peroxide to produce an organic peracid having a quaternary ammonium group is used as a bleach activator. It was found to be extremely excellent. further,
An example of an organic peracid precursor having an anionic group is JP-B-63-12.
It is disclosed in Japanese Patent No. 520.

These bleach activators are compounds which react with hydrogen peroxide to form an organic peracid under mild conditions such as washing conditions, and are therefore generally unstable to hydrogen peroxide. For this reason it is usually difficult to use these bleach activators as liquid bleaching agents and as a composition consisting of a mixture of solid persalts and dry particles of these bleaching activators to keep them dry. It is commonly used.

As a liquid bleaching composition containing a bleaching activator which produces an organic peracid, JP-A-62-230897 discloses a solid bleaching activator in an acidic aqueous solution containing hydrogen peroxide. Disclosed is a composition which is excellent in storage stability and is active at low temperature. However, since the bleaching activator was dispersed in this composition, it was precipitated and separated during storage, and the use was remarkably impaired. Further, this composition has a problem that the bleaching activator is gradually decomposed by being stored in an aqueous solution, and a satisfactory bleaching power cannot be obtained at the time of use. Further, this composition had a bleaching activator dispersed therein, and there was a problem that the bleaching activator remained undissolved during actual bleaching, and when it adhered to the bleached substance, the dye in that part was decolorized. .

[0006] Therefore, the problem to be solved by the present invention is to provide a liquid bleaching agent which has extremely excellent storage stability and does not cause decolorization of the dye.
