  • Patent number: 6391844
    Abstract: A non-tower process for continuously preparing a granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the steps of: (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, while wetting the surfactant coated with the fine powder with finely atomized liquid, in a mixer, and (b) thoroughly mixing the agglomerates in a mixer. Step (b) can also be followed by further step (c), i.e., granulating the agglomerates from step (b) in one or more fluidizing apparatus, during which further coating can be used to prevent over-agglomeration.

    Abstract: Aqueous detergent concentrates containing a mixture of two or more surfactants having a differing resistance to electrolytic salting out in the form of micellar solutions and having pourable viscosities are converted into lamellar solutions upon dilution with water where the dispersion contains a viscosity promoting electrolyte present at a narrow range of concentration. Transformation from the micellar phase to the lamellar phase produces an increase in viscosity such that the diluted concentrate has a viscosity equal to or higher than the viscosity of the original concentrate.
