面が増えることからその傾向は顕著である。2. Description of the Related Art It is known that detergent particles containing a large amount of a nonionic surfactant have a high detergency against sebum stains. In addition, nonionic surfactants having high detergency against sebum stains often have a melting point of 40 ° C. or less,
When a large amount of the nonionic surfactant is incorporated, the nonionic surfactant exudes particularly under high temperature conditions such as in summer. When such a detergent particle group is filled in a paper container such as a commercially available one, dark spots are generated because the exuded nonionic surface activity permeates the paper container and produces a wet color. Significantly impairs product value. In addition, during long-term storage, there is a problem in that the nonionic surfactant attacks the printed surface of the container surface and significantly deteriorates the appearance of the product. In such a problem, a detergent in which the inner surface of a paper container is coated with a film is commercially available, but when a detergent particle group or a detergent particle group having a high moisture content that does not sufficiently suppress bleeding is filled, the detergent particle adheres to the film surface and looks like. There was a problem that worsened. The tendency is remarkable because detergent particles having a small average particle size and a broad particle size distribution, as seen in conventional detergents, have a high filling efficiency and increase the contact surface with the inner surface of the container.

粒子群を得ることができる。The method of producing the detergent particles is as follows. The detergent particles are obtained by drying a slurry containing water-insoluble inorganic salts, a water-soluble polymer, and a water-soluble salt. It is desirable to carry a mixture of surfactants. The dry particles obtained according to the present method have a sharp particle size distribution, and are generally used when producing a high bulk density detergent because the dry particles have an oil absorbing ability to carry a surfactant. It is difficult for the particles to grow in the granulation step to be performed, and a group of detergent particles suitable for obtaining the effects of the present invention can be obtained.

A paperboard formed by laminating a back liner paper having a basis weight of 60 to 300 g / m 2 through a coated resin ball of 0 to 600 g / m 2 via an extruded polyethylene resin layer was used, and the surface was coated with an olefin polymer film or varnish. As the olefin polymer film, polyethylene and polypropylene were used, and as the varnish, acrylic, urethane, epoxy varnish and varnish obtained by mixing acrylic and urethane resin were used. The olefin polymer film was extruded by lamination so as to have a thickness of 20 μm, and the varnish was applied by a gravure coater so that the coating thickness was 20 μm. The paperboard was treated with a fluorine-based sizing agent (Asahigard AG-530: Asahi Glass Co., Ltd.), and an acrylic varnish was applied under the above conditions. The surface-coated paper was assembled in a box shape of L × W × H = 150 mm × 90 mm × 130 mm, and bonded with a vinyl acetate resin emulsion type adhesive to obtain a container.

An aqueous slurry having a water content of 50% was prepared by weight% of components other than the amorphous aluminosilicate, the enzyme, the fragrance and the crystalline silicate, and spray-dried. The obtained spray-dried particles, 3% by weight of nonionic surfactant and 4% by weight of zeolite were charged into a high-speed mixer (stirring-rolling granulator, Fukae Kogyo Co., Ltd.) to perform granulation. . Further, 3% by weight of zeolite, amorphous aluminosilicate, and crystalline silicate were added to perform surface modification to obtain a detergent particle group. The obtained detergent particles were put in a rotary kiln, the enzyme was blended, and simultaneously a fragrance was sprayed to obtain a powder detergent. The water content was controlled by spray drying conditions and fluidized bed drying of the granulated particles. The particle size was controlled by cutting fine particles and coarse particles using a sieve.
