Claims9
A process for making beads for cleaning compositions comprising the steps of:
- a) compacting an anionic surfactant and a dry granular component selected from the group consisting of zeolites, phosphate, sodium carbonate, and mixtures thereof, said granular component containing less than 4.5% by weight of free-moisture, and optionally a binder component, to form granules containing less than 4.5% by weight of free moisture said granules being free of bleach or enzymes;
- and
- b) contacting said granules with amount of water, said water being free of inorganic salts and acids, sufficient to obtain beads with a free-moisture level of from 5.5% to 15% by weight of the beads.
