Abstract:
1. A solid detergent composition precursor consisting of: (a) at least about 40 wt. % hydratable alkali metal hydroxide; (b) about 10 wt. % to about 30 wt. % of a mixture of anionic, cationic, and nonionic surfactants, (c) water in an amount sufficient to allow the detergent composition precursor to solidify; (d) at least about 1 wt. % of an ethylene-diaminetetraacetic acid viscosity control component to lower the viscosity of the detergent composition precursor; (e) a sequestrant selected from the group consisting of acrylic acid polymers and acryl amide polymers; (f) sodium metasilicate; (g) optionally a chelating agent; (h) optionally a flocculent; and (i) optionally a corrosion inhibitor.
