Machine dishwashing powder compositions are disclosed comprising a layered clay in the form of granulated particles obtained by: 1) co-granulating a finely divided clay with a solid particulate material using a water-soluble polymeric material as binding agent; 2) conglutinating a finely divided clay with sodium disilicate carrier material employing water-soluble nonionic surfactant as conglutinating agent; or 3) granulating a finely divided clay with water or an alkaline silicate solution. The granulated clay particles disperse well and do not cause clay deposit on and blocking of the dishwashing machine filter.
