  • Solid detergent compositions
    Patent number: 6964945
    Abstract: The invention relates to solid detergent compositions comprising an aluminosilicate builder and an anionic surfactant and comprising (n) components (i), n being at least 2, whereby the level of aluminosilicate builder in said components together is at least 5% by weight of the composition and the level of the anionic surfactant in said components together is at least 5% by weight of the composition, and whereby the degree of mixture (M) of the anionic surfactant and the aluminosilicate builder is from 0 to 0.7, as defined in the description.

  • Process for making granular detergents
    Patent number: 5998356
    Abstract: A process for making granular detergents is disclosed. In a first step, an aqueous slurry is formed. The aqueous slurry comprises anionic surfactant, chelating agents, at least 0.5%, by weight, of sodium aluminosilicate, and inorganic salts of a type which raise the ionic conductivity of the aqueous slurry. The aqueous slurry contains essentially no silicates and has a low viscosity suitable for spray-drying to form crisp, free-flowing powder. After being formed, the slurry is dried to form a particulate detergent composition.
