Abstract
Detergent compositions and methods of preparing and using the detergent compositions are disclosed. The detergent compositions comprise a polymer system comprising at least one polycarboxylic acid polymer, copolymer, or terpolymer, an alkalinity source comprising an alkali metal carbonate, a nonionic surfactant and water. The detergent compositions are suitable at alkaline pH and reduce or prevent scale formation, improve soil dispersion, and provide effective detergency.
