NON-GELLING INORGANIC SALT CRUTCHER SLURRIES ABSTRACT OF THE DISCLOSURE 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. The present invention relates to non-gelling aqueous slurries of inorganic salt mixtures and to methods for their manufacture. More particularly, it relates to the utilization of certain materials, which, in combination, exert an exceptionally good and improved anti-gelling action, preventing gelation, excess thickening and setting up of bicarbonate - carbonate - silicate slurries, from which particulate heavy duty synthetic organic detergent composi- tions may be made, as by spray drying and post-spraying. - 1 -
