Abstract: Detergent compositions contain sticky particles with at least 45% by weight of a sticky surfactant and non-sticky particles with less than about 1% by weight of sticky surfactant. The particles are further characterized by their size ranges and bulk densities. Compositions containing potassium ions are described. Dissolution of the compositions in aqueous media is optimized.

Abstract: A process for preparing low density detergent agglomerates is provided. The process involves the step of: (a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material having a median particle size in a range from about 5 microns to about 70 microns in a first high speed mixer to obtain detergent agglomerates having a median particle size of from about 100 microns to about 250 microns; (b) mixing the detergent agglomerates with a binder in a second high speed mixer to obtain built-up agglomerates having a median particle size in a range of from 140 microns to about 350 microns; and (c) feeding the built-up agglomerates into a fluid bed dryer in which the built-up agglomerates are agglomerated with another binder and dried to form detergent agglomerates having a median particle size in a range from about 300 microns to about 700 microns and a density in a range from about 300 g/l to about 550 g/l.

Abstract: A method for controlling chemical distribution of substances in a solid state (and products produced thereby), the method comprising the steps of mixing particles of a first powder and a triggerable granule facilitator to form first microcapsules, the first microcapsules each having a core of one of the particles and a cladding of the facilitator; and triggering the facilitator while dry mixing the microcapsules to form substantially spherical granules of the microcapsules, the granules each having a controlled chemical distribution.The method also includes the steps of mixing particles of a second powder with the facilitator to form second microcapsules, the second microcapsules each having a core of one of the particles of the second powder and a cladding of the facilitator; and then mixing the first and the second microcapsules prior to said triggering step.
