Abstract
A process for the production of a spray-dried detergent powder including a hexagonal-phase-in-water-forming surfactant the process including the steps of: (i) spraying into a spray-drying tower a detergent slurry preferably free of a hexagonal-phase-in-water-forming surfactant; and (ii) simultaneously spraying a paste having a hexagonal-phase-in-water-forming surfactant, whereby droplets of the slurry encounter droplets or powder of the hexagonal-phase-in-water-forming surfactant paste so as to form composite granules.

A process for the production of a spray-dried detergent powder comprising a hexagonal-phase-in-water-forming surfactant the process comprising the steps of:
- (i) spraying into a spray-drying tower a detergent slurry free of a hexagonal-phase-in-water-forming surfactant;
- and
- (ii) simultaneously spraying a paste comprising a hexagonal-phase-in-water-forming surfactant,
- whereby droplets of the slurry encounter droplets or powder of the hexagonal-phase-in-water-forming surfactant paste so as to form composite granules.
A spray-dried granular detergent composition including composite granules comprising:
- (i) a core granule comprising one or more anionic and/or nonionic detergent-active compounds that is free of a hexagonal-phase-in-water-forming surfactant, and
- (ii) an outer layer, in the form of a coating or of smaller particles, comprising a hexagonal-phase-in-water-forming surfactant.
