Bleaching agents and bleach activators tend to gradually decompose and lose activity due to alkali components, moisture and the like in the bleaching detergent. In addition, when zeolite is blended, the primary particles are usually used in the form of agglomerated particles, and during the mixing and stirring during production, a part of the zeolite is disintegrated due to the friction between particles and the like, and fine powder is generated. There is. The presence of such a large amount of zeolite fine powder accelerates the decomposition of the bleach activator and inorganic peroxide.
