摘要： PROBLEM TO BE SOLVED: To provide scrub granules disintegrable due to the decrease in the concentration of a water-soluble salt in an aqueous solution containing the salt and having a layer structure, therefore causing a dispersion of the whole particles in water simultaneously with the crust disintegration, thus giving high rinsing ability, furthermore affording good feeling when used according to circumstances in use and easy to control the disintegrability by selecting as appropriate the primary particles constituting both the crust and core of the disintegrable particles and both the kind and amount of a binder. SOLUTION: The scrub granules of layer structure comprises a core >=80 wt.% in disintegrability due to a 10 wt.% saline solution and a crust containing a salt-sensitive and water-soluble binder.

摘要： PROBLEM TO BE SOLVED: To provide enzyme particle aggregate from which the enzymes are readily eluted out without the enzyme residue insoluble with occurrence of dusting suppressed, resisting the occurrence of classification in the detergent composition, when it is formulated to the detergent together with other components, by coagulating enzyme particles having such a structure that the water-soluble binder distributes more in the vicinity of the surface than in the core part, and provide a method for suitably producing an aggregate of enzyme particles. SOLUTION: The objective aggregate comprises (A) water-insoluble and/or slightly soluble substance, (B) a water-soluble binder and (C) enzymes and has such a structure that the component (B) distributes more in the vicinity of the surface than in the core part. The objective enzyme particle aggregate is produced by adding water or a binder aqueous solution to the enzyme particles having the above-stated structure, drying and/or cooling the mixture or by adding a molten thermoplastic binder thereto, cooling the mixture.
