US Classification:

252 95

Abstract:

The present invention is based upon the discovery that high levels of carbonate salts can be formulated with minor concentrations of phosphates (e. g. , about 0. 1 to 0. 3 percent by weight as expressed as (P. sub. 2 O. sub. 5) together with low levels of a mixture of certain polycarboxylate homopolymers and copolymers (i. e. , in combination, a total of about 0. 5 to 8. 0 percent by weight), and relatively high levels of nonionic surfactants in a dishwashing detergent formulation while providing satisfactory cleaning without unacceptable spotting and filming and without the need to add a chlorinating agent.

Abstract:

The present invention is based upon the discovery that high levels of carbonate salts can be formulated with minor concentrations of phosphates (e. g. , about 0. 1 to 0. 3 percent by weight as expressed as (P. sub. 2 O. sub. 5) ion) together with low levels of polycarboxylate homopolymers and copolymers (i. e. , about 0. 5 to 5. 0 percent by weight) in a dishwashing detergent formulation while providing satisfactory cleaning without unacceptable spotting and filming and without the need to add a chlorinating agent.
