Description

  The present invention relates to a liquid bleach detergent composition.

  Liquid detergents are widely used because they are superior in terms of simplicity in that they have no undissolved residue in water and can be directly applied to soiled parts as compared with powder detergents. On the other hand, hydrogen peroxide is used as an oxygen bleaching agent because it exhibits a bleaching effect at a pH of weak alkalinity or higher. However, it is difficult to incorporate hydrogen peroxide in a liquid detergent that is alkaline from the viewpoint of storage stability.

  The bleach activator can react with hydrogen peroxide in a pH range of weak alkalinity or higher, and can exert a bleaching effect and a sterilizing / deodorizing effect. Since it significantly decreases, it is difficult to blend a bleach activator with a liquid detergent composition generally adjusted to a high pH region in terms of storage stability. On the other hand, spilled stains and the like are known to have a very high bleaching effect by the bleach activator, and it is strongly required to impart a bleaching effect to the liquid detergent.

For the purpose of achieving both the stability of the bleach activator and the bleaching effect, a technology (pH jump technology) is known in which the pH of the product of the liquid detergent composition is weakly acidified and diluted with water to increase the pH (pH jump technology). Yes. These are achieved by using a boron compound and a polyhydric alcohol such as sugar in combination, and are disclosed in Patent Documents 1 to 6. Patent Document 4 also discloses a composition containing a precursor of a bleach activator that exerts an effect on stain stains caused by eating spills, and decanoyloxybenzoic acid is exemplified. Furthermore, Patent Document 7 discloses a liquid bleaching composition containing an organic peracid precursor having a branched structure, and describes that it has excellent stability.

  Many of the techniques described in Patent Documents 1 to 6 adjust the pH of the composition to 4.5 or less and show a pH jump effect, but the reached pH is less than 8, and the expected bleaching effect Is not sufficiently exhibited, and the cleaning effect is not satisfactory.

  In order to obtain a satisfactory bleaching effect and washing effect when diluted, it is necessary to raise the pH to, for example, pH 8 or higher, and as a means for achieving this, the pH of the composition needs to be adjusted to 4.6 or higher in advance. . In this case, however, there is a problem with the stability of the bleach activator. In addition, in the compositions described in Examples in Patent Documents 4 and 5, the cleaning effect when the composition is used alone is low, and it does not reach a satisfactory level. Further, in Patent Document 7, when a liquid bleaching agent composition is stored, there is a problem that odor deterioration is caused by a fatty acid salt generated by hydrolysis of a bleaching activator.

  Accordingly, an object of the present invention is to have a pH jumping effect at a level at which the bleaching effect and the washing effect can be satisfied, dramatically improve the storage stability of hydrogen peroxide and a bleach activator, and further improve the composition after storage. An object of the present invention is to provide a liquid bleaching detergent composition with suppressed odor.
