Abstract:
A spray-dried amorphous alkali metal silicate compound providing multiple-cycle washing performance and having a molar ratio of M2O to SiO2 of 1:1.5 to 1:3.3, wherein M represents an alkali metal, the compound consisting essentially of 15 to 80% by weight of alkali metal silicate, an alkali metal carbonate, 0.5 to less than 20% by weight of an anionic surfactant comprising a C9-13 alkyl benzene sulfonate, and water, all weights being based on the weight of the alkali metal silicate compound, the compound having an absorption capacity for liquid components which is at least 20% higher than that of the same quantity of the alkali metal silicate which is free from anionic surfactant, and wherein the compound is aftertreated with liquid components that are ingredients of detergents or cleaning composition.
