Description

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 particularly to a liquid containing a bleaching activator which reacts with hydrogen peroxide having excellent storage stability to produce an organic peracid. It relates to a bleach composition.

[0002]

BACKGROUND OF THE INVENTION Bleaching agents are classified into chlorine bleaching agents and oxygen bleaching agents. Chlorine bleaching agents are limited in the types of fibers that can be used, and cannot be used for colors and patterns. Oxygen bleaching agents that do not have these disadvantages have recently become very popular because of their unique odor. Among these oxygen bleaching agents, sodium percarbonate and sodium perborate are used as powder bleaching agents, and hydrogen peroxide is used as a liquid bleaching agent.

[0003] However, these oxygen bleaching agents have a weak bleaching power as compared with chlorine bleaching agents, and various bleaching activators are used in combination. These bleach activators include, for example, O represented by glucose pentaacetate (GPAC).
-Acetylated products, N-acylated products typified by tetraacetylethylenediamine, acid anhydrides typified by maleic anhydride, and the like. Furthermore, the present inventors have JP 63-233969, JP Sho 63-31566 6 JP, Sho 64-68347 discloses, as disclosed in JP-A-1-190654 Patent Publication It has been found that compounds which react with hydrogen peroxide to produce an organic peracid having a quaternary ammonium group are extremely excellent as bleach activators. Furthermore, an example of an organic peracid precursor having an anionic group is disclosed in
No. 12520.

[0004] These bleach activators are compounds that react with hydrogen peroxide under mild conditions of washing conditions to produce organic peracids, and are therefore generally unstable to hydrogen peroxide. For this reason, these bleach activators are usually difficult to use as liquid bleaches, and in order to keep them dry, they are used as compositions consisting of a mixture of solid persalt and dry particles of these bleach activators. It is generally used.

A liquid bleaching agent composition containing a bleaching activator for producing an organic peracid is disclosed in Japanese Patent Application Laid-Open No. 62-230897, which is a solid bleaching activator in an acidic aqueous solution containing hydrogen peroxide. A composition having excellent storage stability and exhibiting activity at a low temperature is disclosed. However, this composition precipitates and separates during storage due to the dispersion of the bleach activator, and significantly detracts from its use. 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, in this composition, the bleaching activator is present in a dispersed state, and the bleaching activator remains undissolved during actual bleaching, and when it adheres to the bleached material, there is a problem that the dye in that portion is decolorized. .

The inventors of the present invention have conducted intensive studies on a liquid bleaching composition having excellent storage stability.
No. 487 discloses a liquid bleach composition comprising hydrogen peroxide, an amphoteric surfactant and a bleach activator. However, this composition is still insufficient in storage stability and has a problem in the decolorization of the dye.

[0007] Accordingly, an object of the present invention is to provide a liquid bleach which is extremely excellent in storage stability and does not cause decolorization of a dye.

[0008]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above problems, and as a result, have found that the above object can be achieved by a combination of extremely specific components, and have completed the present invention. .

That is, the present invention comprises the following components (a), (b), (c) , (d) and water , and has a pH of 6 or less.

[Liquid bleach composition] In the composition of the present invention, component (a) is incorporated in an amount of 0.3 to 30% by weight, preferably 0.5 to 20% by weight, more preferably 0.5 to 10% by weight in the composition. (b) The amount of the component is 0.1 to 20% by weight, preferably
0.1 to 10% by weight, more preferably 0.5 to 5% by weight, and the amount of component (c) is 0.1 to 30% by weight, more preferably 0.1 to 20% by weight.
% By weight, more preferably 0.5 to 10% by weight, and the amount of component (d) is 0.5 to 30% by weight, preferably 1.0 to 20% by weight, and more preferably 5.0 to 20% by weight. In this case
The component (b) and the component (c) are weight ratio [component (b)] / [(c)
Component] = 1/50 to 5/1, preferably 1/20 to 2/1.

If the amount of component (a) is less than 0.3% by weight, sufficient bleaching performance cannot be obtained. On the other hand, if it exceeds 30% by weight, it is dangerous because the storage stability of hydrogen peroxide itself becomes unstable. If the amount of component (b) is less than 0.1% by weight, sufficient bleaching performance cannot be obtained. On the other hand, when the content exceeds 20% by weight, the color pattern tends to be decolorized. (c) If the compounding amount of the component is outside the range of 0.1% by weight to 30% by weight, the storage stability tends to decrease. If the amount of the component (d) is outside the range of 0.5 to 30% by weight, the storage stability tends to decrease. Then, the weight ratio of component (b) to component (c) [component (b)] /
If the component (c) is less than 1/50, sufficient bleaching performance cannot be obtained, while if it exceeds 5/1, the storage stability of the component (b) tends to be poor.

Although it is not always clear why a bleaching composition having excellent storage stability can be obtained in the present invention, the component (b) and the component (c) form a complex, and this complex is formed. This is probably because component (d) surrounds and prevents component (b) from coming into direct contact with component (a).
