Abstract
Tablets having a broad solubility profile containing a mixture of sodium metasilicate nonahydrate and anhydrous sodium metasilicate with a grain size of from 0.2 to 0.8 mm in a ratio by weight of from 1:0.75 to 1:1.2, anhydrous pentasodium triphosphate having a grain diameter of 0.2 to 0.3 mm, and 0.5 to 5% by weight of an active chlorine donor. The ratio by weight of pentasodium triphosphate to metasilicates is about 1:1 to 1:1.7, based on anhydrous substances. The tablets are used in automatic dishwashing machines where they are introduced into a free zone of the machine before the start of the prerinse cycle, at least 10% of the tablets being dissolved by inflowing cold water and at least another 70% being available in the main-wash cycle.
