ABSTRACT:
A high caustic paste dishwashing detergent is formulated to avoid reversion of the polyphosphates. The composition which includes at least about 35% sodium hydroxide (solids) is formulated with up to 30% of a phosphate sequestering system. The phosphate sequestering system includes preferably equal proportions of tetra alkali metal pyrophosphate and alkali metal tripolyphosphate. The high percentage of pyrophosphate is added to further stabilize the phosphate system. The detergent composition also includes a low molecular weight polyacrylic acid, a phosphono alkyl tricarboxylic acid, colloidal silica and a gluconate and optionally a chlorine source and defoamer. Preferably the composition includes at least about 40% sodium hydroxide, 10% tetra sodium pyrophosphate and 10% sodium tripolyphosphate with the remainder formed from the polyacrylate, phosphono butane tricarboxylic acid, sodium gluconate, colloidal silica, Chloramine T and water.
