Therefore, the liquid type bleach is generally adjusted to be acidic. However, although the decomposition of the bleach is suppressed,
Even in the acidic region, the stability of the bleaching agent is not sufficient when stored at high temperature. BACKGROUND ART Heretofore, studies have been earnestly made to improve the storage stability of a liquid bleach containing hydrogen peroxide. For example, Japanese Examined Patent Publication (Kokoku) No. 40-7774 discloses a storage-stable weakly acidic liquid bleach containing a combination of acidic sodium pyrophosphate, neutral sodium pyrophosphate and potassium pyrophosphate. Further, in JP-A-49-52784, alkylidene diphosphonic acid, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid and nitrilotrimethylenephosphonic acid organic acid selected from soluble tin salt and ammonium salt pH is 0. A stable liquid bleach of 0.5 to 7 is disclosed. Further, JP-A-52-103386 discloses a hydrogen peroxide stabilizer comprising poly-α-hydroxyacrylic acid. Further, JP-A-55-108500 discloses a stable liquid bleaching agent having a pH of 1.8 to 5.5, in which an acid selected from organic acids, phosphoric acid and boric acid is mixed with a nitrogen compound. Has been done. Further, in JP-A-55-76161, a synergistic stabilizing effect is exhibited by blending poly-α-hydroxyacrylate in an alkaline hydrogen peroxide bleaching system using condensed phosphate as a stabilizer. Is disclosed. Further, JP-A-57-154457 discloses a stabilizing aid for a hydrogen peroxide bleaching agent, which comprises a copolymer of acrylic acid and an acrylic ester and / or polyerylene glycol methacrylate. There is. In addition, JP
-185797 discloses a hydrogen peroxide-based bleaching stabilizer in which a poly-α-hydroxyacrylic acid salt and an organic phosphonate are used in combination. Furthermore, as an acidic hydrogen peroxide-based bleaching composition with improved storage stability at high temperature, JP-A-3-
Japanese Patent No. 91597 discloses an example in which polyacrylic acid having a specific molecular weight or a salt thereof is blended in a specific surfactant system. Further, JP-A-3-188198 discloses an example in which a polyacrylic acid polymer and / or a maleic acid polymer having a specific molecular weight in a specific surfactant system and a specific phosphorus compound are blended. Further, JP-A-4-23897 discloses an example in which a nonionic surfactant, a carboxylic acid polymer and a specific organic phosphonic acid compound are combined. Further, JP-A-4-28797 discloses an example in which a polycarboxylic acid having a specific molecular weight or a salt thereof in a specific surfactant system and a specific water-soluble inorganic salt are mixed.

[0003]

However, the hydrogen peroxide type bleaching agent using these stabilizers has a problem that the storage stability at high temperature is not sufficient, or liquid separation or a precipitate is generated during low temperature storage. Occurred. Further, there is a problem that the aroma stability of the blended fragrance is remarkably lowered during high temperature storage.
