JP-B-51-39966). However, although these are widely used for bleaching for clothes, bleaching and sterilization for kitchens, removal of molds generated in bathrooms, etc., they have a drawback of low bleaching effect against oil-based stains. Therefore, an object of the present invention is to provide a liquid bleaching agent containing hypochlorite and exhibiting an extremely excellent bleaching power for oil-based stains.

[0003]

The present inventors have found that the following and hypochlorite ions have a sufficient oxidizing power, but have a low bleaching power against oil stains because they have a low penetrating power into oil. It is not considered that the combination of conventionally proposed hypochlorite and a specific surfactant can obtain the detergency of the surfactant, but the penetration of hypochlorite ion into oil is small. It is presumed that a sufficient bleaching effect may not be obtained, and as a result of diligent studies on the combination of surfactants that improve the permeation power of hypochlorite ion into oil,
It was found that the intended object can be achieved by combining a hypochlorite, a quaternary ammonium salt type cationic activator, and a specific anionic compound or amphoteric compound, and to complete the present invention. I arrived.

That is, the present invention contains the following component (a), component (b) and component (c), the content of component (a) is 0.5 to 12% by weight, and the content of component (b) is 0.01: The present invention provides a liquid bleaching composition, wherein the content of the component (c) is 0.01 to 20% by weight, and the content of the component (c) is 0.01 to 20% by weight.
