Abstract
A spray-dried amorphous alkali metal silicate compound which provides multiple-cycle washing performance. The silicate compound has a molar ratio of M O to SiO of 1:1.5 to 1:3.3 wherein M represents an alkali metal. The compound contains 0.5 to less than 30% by weight of anionic surfactant and has an absorption capacity for liquid components which is at least 20% higher than that of the same quantity of the alkali metal silicate compound which is free from anionic surfactant.
