Abstract
A process for making a particle comprising at least 45 wt % sulphate, from 0 wt % to 15 wt % anionic detersive surfactant, and having a bulk density of from 350 g/l to 700 g/l, comprising the steps of; (a) preparing an aqueous slurry comprising sulphate, and optionally detersive surfactant; (b) drying the particle; and wherein the sulphate added to the aqueous slurry has a volume average particle size of from 10 micrometers to 50 micrometers.
Claims18
A process for making a particle comprising at least about 55 wt % sulphate, from about 0 wt % to about 15 wt % anionic detersive surfactant, and having a bulk density of from about 350 g/l to about 700 g/l, comprising the steps of;
- a) preparing an aqueous slurry comprising sulphate and optionally detersive surfactant;
- b) drying the particle;
- and wherein the sulphate added to the aqueous slurry has a volume average particle size of from about 20 micrometers to about 45 micrometers.
A particle comprising at least about 55 wt % sulphate, from about 0 wt % to about 15 wt % anionic detersive surfactant, and having a bulk density of from about 350 g/l to about 700 g/l wherein the particle is spray-dried or flash-dried and the sulphate added to the aqueous slurry has a volume average particle size of from about 20 micrometers to about 45 micrometers.
