The present invention relates to a cleaning tablet composition for a dishwasher, a cleaning tablet for a dishwasher, and a method for producing a cleaning tablet for a dishwasher. This application claims priority to Japanese Patent Application No. 2015-028263 filed on February 17, 2015, the contents of which are incorporated herein by reference.

At present, dishwashers are popular in ordinary households in Japan, and many detergents for dishwashers are sold. Unlike general dishwashing detergents, detergents for dishwashers are required to reduce foaming properties. For this reason, powdery dishwasher detergents use non-ionic surfactants with low foaming properties, alkaline agents such as alkali metal carbonates, water softeners such as phosphates and carboxylates, bleaching Those containing components such as agents, enzymes, and dispersants are the mainstream.

As for detergents for dishwashers, powdered ones are likely to scatter and have problems with operability and safety. Therefore, it is desirable to form them into solids such as tablets and tablets. Has been. Solid detergents need to disintegrate and dissolve at a sufficient rate in water at the time of use, but unsolved residue is a problem in some products. Therefore, what uses the foaming agent which consists of a combination of carbonate and an organic acid as a disintegration aid is also known (patent document 2).
Furthermore, there is known a foamable cleaning composition for a dishwasher comprising a cleaning component comprising an oxidizing agent, a carbon dioxide generating component comprising an acid and an alkali, and a surfactant (Patent Document) 3). Specific examples of carbon dioxide generating components include organic acids such as citric acid and succinic acid as acids, and carbonates such as sodium hydrogen carbonate and potassium hydrogen carbonate as alkalis. It describes that a lubricant such as talc and a binder such as hydroxypropylcellulose may be included. Further, it is described that the form of the composition can be appropriately changed depending on the use and purpose, and can be made into a tablet.

However, when a general powdered granular composition is directly tableted into tablets, it is possible to obtain a well-balanced tablet that satisfies all the properties such as productivity, prevention of abrasion during storage and transportation, and disintegration time during use. could not.
