Abstract:
A detergent composition for preventing scale on various surfaces includes a threshold system, a caustic and a surfactant system. The threshold system includes a sulfonate/acrylate copolymer, an acrylate homopolymer and a phosphonoalkane carboxylic acid with a sulfonate/acrylate copolymer to acrylate homopolymer weight ratio of between about 2:1 to about 1:2. The pH of the detergent composition is between about 10 and about 13.
