METHOD FOR SUPPLYING DETERGENT TO AUTOMATIC WASHING MACHINE, TABLET DETERGENT COMPOSITION FOR AUTOMATIC WASHING MACHINE USED THEREFOR, AND WASHING METHOD USING SAME

摘要

The present invention provides a method capable of supplying a detergent solution of a stable concentration to an automatic washing machine by using a detergent supply apparatus of inexpensive structure; a tablet detergent composition for an automatic washing machine that is used in the method and that excels in a dissolution characteristic, washing characteristic, storage characteristic and the like; and a washing method using the composition. A tablet detergent composition comprising (A) a metal salt of a saturated fatty acid, (B) a silicate, (C) an aminocarboxylic acid salt, and (D) a nonionic surfactant as essential components at specific content ratios is accommodated inside a casing of a detergent supply apparatus disposed in an automatic washing machine. Washing water or rinsing water sprayed inside the automatic washing machine is brought into contact with the tablet detergent composition, and a detergent solution of a high-concentration that has been dissolved is caused to flow into a washing tank of the automatic washing machine, and washing water of a desired concentration is prepared and supplied to wash the articles to be washed.
