• said builder is water-soluble and is at least one member selected from the group consisting of:
• alkali metal polyphosphates, alkali metal phosphonates, alkali metal polyphosphonates, alkali metal carbonates, alkali metal silicates, alkali metal borates, alkali metal polyhydroxysulfonates, and alkali metal polyacetates, alkali metal carboxylates, alkali metal polycarboxylates, and alkali metal polyhydroxysulfonates, and ammonium or substituted ammonium phosphates, ammonium or substituted ammonium polyphosphates, ammonium or substituted ammonium phosphonates, ammonium or substituted ammonium polyphosphonates, ammonium or substituted ammonium carbonates, ammonium or substituted ammonium silicates, ammonium or substituted ammonium borates, ammonium or substituted ammonium polyhydroxysulfonates, ammonium or substituted ammonium polyacetates, ammonium or substituted ammonium carboxylates, and ammonium or substituted ammonium polycarboxylates, ammonium or substituted ammonium polyhydroxysulfonates, sodium and potassium carboxymethyloxymalonate, carboxymethyloxysuccinate, cis-cyclohexanehexacarboxylate, cis-cyclopentanetetracarboxylate, phloroglucinol trisulfonate, water-soluble polyacrylates having molecular weights of from about 2,000 to about 200,000, and the copolymers of maleic anhydride with vinyl methyl ether or ethylene, amorphous and crystalline alumino silicates, and hydrated sodium Zeolite A;
• (c)(I) a water-soluble or dispersible organophosphorus material selected from the group consisting of:
• (c)(I)(1) organophosphorus compounds according to structure (I):
• wherein:
• each R1 is and each R2 is independently absent or O, provided that at least one of R1 and R2 is O,
• each R3 is independently alkyleneoxy or poly(alkyleneoxy), which may optionally, be substituted on one or more carbon atom of such alkyleneoxy or poly(alkyleneoxy) group by hydroxyl, alkyl , hydroxyalkyl, alkoxy, alkenyl, aryl, or aryloxy,
• R5 is and each R4 is independently absent or alkyleneoxy or poly(alkyleneoxy), which may optionally, be substituted on one or more carbon atom of such alkyleneoxy or poly(alkyleneoxy) group by hydroxyl, alkyl, hydroxyalkyl, alkoxy, alkenyl, aryl, or aryloxy,
• R6 and R8 are each and each R7 is independently H, or (C1-C30)hydrocarbon, which hydrocarbon may optionally be substituted on one or more carbon atoms by hydroxyl, fluorine, alkyl, alkenyl or aryl and/or interrupted at one or more sites by an O, N, or S heteroatom, or —POR9R10,
• R9 and R10 are each independently hydroxyl, alkoxy, aryloxy, or (C1-C30)hydrocarbon, which hydrocarbon may optionally be substituted on one or more carbon atoms by hydroxyl, fluorine, alkyl, alkenyl or aryl and/or interrupted at one or more sites by an O, N, or S heteroatom, and
• m is an integer of from 2 to 5,
• (c)(I)(2) salts of organophosphorus compounds according to structure (I) wherein m is an integer of from 2 to 5,
• (c)(I)(3) condensation reaction products of two or more molecules of one or more organophosphorus compounds according to structure (I) wherein m is an integer of from 1 to 5 for each said molecule, and
• (c)(I)(4) mixtures comprising two or more of the compounds, salts, and/or reaction products of (c)(I)(1), (c)(I)(2), and (c)(I)(3);
• provided that a 10% aqueous solution of said detergent composition has a pH of from about 4 to about 12.
