Abstract
Gelation and setting of desirably miscible and pumpable crutcher slurries comprising sodium carbonate, sodium bicarbonate and sodium silicate in an aqueous medium are retarded and often prevented by the addition to such medium of a citric material, such as citric acid and/or water soluble citrate, and magnesium sulfate. Alternatively, magnesium citrate may be employed. The addition of the citric material and magnesium sulfate (or magnesium citrate) lengthens appreciably the workable crutcher time before setting, increasing it over such working time for similar crutcher mixes containing the citric material but not containing magnesium sulfate. The improved workability of the crutcher mix permits the making of higher solids content crutcher slurries, thereby resulting in significant energy savings and increases in production rates when the crutcher slurries are subsequently spray dried to free flowing inorganic salt base bead form, from which detergent compositions may be made by post-spraying with nonionic synthetic organic detergent in liquid state.
