It is desirable to adjust the amount of the component (e) so that the concentration of the component (e) in the mixture is 0.01 to 30% by weight, preferably 0.1 to 20% by weight. Further, it is desirable to adjust the components in each package so that the pH of the mixture at the time of use is 7 to 13, preferably 8 to 13.
In addition, what was illustrated above is used as an arbitrary component. In addition, as a method of packaging, any method may be used as long as it does not affect the contents, and specifically, a method of filling resin bottles or small bags. At that time, the sachet (I) is packaged in a bottle and sachet (II) is sachet, or sachets (I) and (II) are sachets.
, (II) can be any combination, such as bottles, and the number of bottles and sachets can be any number. The material of the resin that composes bottles and sachets is polyethylene, polypropylene, nylon,
Any material that is generally used such as polyethylene terephthalate, polyvinylidene chloride, polyvinyl chloride, and glass may be used. In addition, a pigment, an antistatic agent, a light-shielding agent, an ultraviolet absorber, and the like which are generally used in a resin container of a detergent composition or a bleaching agent composition can be contained. Further, for the purpose of increasing the strength of the package or improving the storage stability, the same or different types of resins or metals such as aluminum can be laminated or vapor-deposited. Further, the filling container may be provided with a gas release mechanism such as a pinhole or a check valve for the purpose of preventing rupture due to gas generated from the contents. The filling container may be provided with a discharge mechanism such as a trigger sprayer or a foamer, or a straw-shaped one that is convenient for transferring the content liquid to another container. Regarding the size and shape of the filling container, any size and shape may be used as long as the contents of the packages (I) and (II) fall within the above-mentioned ratios when used.
