ABSTRACT:
Compositions suitable for use as detergents comprise a non-silicate-coated alkali metal phosphate salt hydrated to at least about 50% by weight, and an inorganic salt selected from alkali metal carbonates and sulfates. The compositions for use in, e.g. dishwashing, have improved solubility and dispersion characteristics.
