ABSTRACT:
A non-bleaching cleaning composition, e.g. laundry detergent, wherein the solids content comprises at least about 70 wt. % of sodium carbonate, and up to about 12 wt. % of elemental magnesium in the form of a water soluble salt, e.g., magnesium sulfate or magnesium chloride, based on the total weight of the solids composition. Preferably the composition also contains an active surfactant and, when used as a laundry detergent, a polymeric polycarboxylate, e.g., an acrylic acid polymer. Incorporation of magnesium ions in the foregoing cleaning composition containing carbonate ions is intended to minimize negative interactions that will occur between the precipitation of calcium carbonate and the substrate being cleaned, e.g., fabric encrustation when the composition is used as a laundry detergent.
