  • Amorphous alkali metal silicate compound
    Patent number: 6458755
    Abstract: A spray-dried amorphous alkali metal silicate compound which provides multiple-cycle washing performance. The silicate compound has a molar ratio of M2O to SiO2 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.

  • Method for preparing an amorphous alkali silicate with impregnation
    Patent number: 5958864
    Abstract: A process for producing a particulate amorphous alkali metal silicate having a molar ratio of M.sub.2 O to SiO.sub.2 of 1:1.5 to 1:3.3 bya) spray-drying an aqueous mixture of amorphous alkali metal silicate,b) impregnating the spray-dried amorphous alkali metal silicate with an aqueous dispersion or solution of detergent composition components containing at least one organic component, andc) optionally drying the impregnated amorphous alkali metal silicate.
