ABSTRACT:
Highly alkaline detergent compositions are prepared by mixing together, in a mixing device, a melt of alkaline material with a heat-alkaline sensitive material, such as, an alkali metal complex phosphate sequestrant and/or an active-chlorine source. The resulting mixture is, then, pelletized on a chill belt. Because of the short contact time between the molten alkaline material and the sequestrant and the rapid solidification, reversion of the sequestrant, particularly, a phosphate sequestrant, is substantially reduced.
