- 2. The formulation of claim 1 wherein the compound (a) is present in an amount of from 5 to 95% and component (b) is present in an amount of from 5 to 95%.
- 3. The composition of claim 1 wherein the compound of (b) is trisodium-2,2,6-tetrahydropyran-tricarboxylate.
- 4. The composition of claim 1 wherein the compound of (b) is tetrasodium-2,2,6,6-tetrahydropyran tetracarboxylate.
- 5. A machine dishwashing composition comprising:
- (a) from 0 to 5% by weight of a surfactant selected from the group consisting of low-foaming anionic and nonionic surfactants and mixtures thereof,
- (b) a chlorine providing material in an amount sufficient to provide from about 0.5 to 2% by weight of available chlorine,
- (c) from 5 to 30% by weight soluble sodium silicate having an SiO.sub.2 to Na.sub.2 O mole ratio of from 1:1 to 3.2:1, and
- (d) from 5 to 90% by weight of one or more compounds having the molecular structure represented by the formula: ##STR12## wherein M is 0 or CY.sub.2, where Y is H or lower alkyl (C.sub.1 to C.sub.4), X is selected from the group consisting of H, lower alkyl (C.sub.1 to C.sub.4), or COOZ, Z represents H, R or a salt forming ion from the group alkali metal, ammonium, or trialkanolammonium, and R is an alkyl group (branched or straight chain) having up to about C.sub.20 in the chain.
- 6. The composition of claim 5 wherein the compound of (d) is trisodium-2,2,6-tetrahydropyran-tricarboxylate.
- 7. The composition of claim 5 wherein the compound of (d) is tetrasodium-2,2,6,6-tetrahydropyran tetracarboxylate.
- 8. A method for washing articles comprising:
- contacting said articles with an aqueous detergent composition,
- said aqueous detergent composition comprising, dissolved in the water of said aqueous composition, a compound of the molecular structure represented by the formula: ##STR13## wherein M is 0 or CY.sub.2, where Y is H or lower alkyl (C.sub.1 to C.sub.4), X is selected from the group consisting of H, lower alkyl (C.sub.1 to C.sub.4), or COOZ, Z represents H, R or a salt forming ion from the group alkali metal, ammonium, or trialkanolammonium, and R is an alkyl group (branched or straight chain) having up to about C.sub.20 in the chain.
- 9. The composition of claim 8 wherein said compound is trisodium-2,2,6-tetrahydropyran-tricarboxylate.
- 10. The composition of claim 8 wherein said compound is tetrasodium-2,2,6,6-tetrahydropyran tetracarboxylate.
