Phosphonate detergent builders

Abstract

Abstract THE INVENTION DISCLOSED IS DIRECTED TO DETERGENT BUILDER COMPOSITIONS INCLUDING: (A) AMINO TRI(LOWER ALKYLIDENEPHOSPHONIC ACIDS), HAVING THE FORMULA: ((HO)2-P(=O)-C(-X)(-Y))3-N WHEREIN X, Y OR BOTH REPRESENT HYDROGEN OR A LOWER ALKYL GROUP (1-4 CARBON ATOMS) OR A WATER-SOLUBLE SALT OR ESTER THEREOF AND (B) A MEMBER OF THE GROUP CONSISTING OF: (1) A WATER SOLUBLE ACRYLIC OR METHACRYLIC ACID POLYMER WHICH IS POLYACRYLIC ACID, POLYMETHYLACRYLIC ACID, ACRYLIC ACID-METHACRYLIC ACID COPOLYMERS, HYDROLYZED POLYACRYLAMIDE, HYDROLYZED POLYMETHACRYLAMIDE, HYDROLYZED ACRYLAMIDE-METHACRYLAMIDE COPOLYMERS, HYDROLYZED POLYACRYLONITRILE, HYDROLYZED POLYMETHACRYLONITRILE, HYDROLYZED ACRYLONITRILE-METHACRYLONITRILE COPOLYMERS, OR MIXTURES OF ANY TWO OR MORE OF THE SAID ACRYLIC POLYMERS; OR WATER-SOLUBLE SALTS OF THESE ACRYLIC POLYMERS, OR POLYMER MIXUTRES; OR (2) A WATER-SOLUBLE ORGANIC COMPLEXING POLYMER BUILDER INGREDIENT HAVING A WEIGHT AVERAGE MOLECULAR WEIGHT OF FROM ABOUT 1,000,000 TO ABOUT 12,000,000 AND COMPRISING A LINEAR ALIPHATIC BACKBONE HAVING N-CARBOXYMETHYL AMINE OR N-CARBOXYMETHYL AMIDE SIDE CHAINS IMPARTING COMPLEXING PROPERTIES TO THE POLYMER; OR A WATER SOLUBLE SALT OF SUCH COMPLEXING POLYMER; OR (3) NITRILOTRIACETIC ACID OR A WATER SOLUBLE SALT THEREOF HAVING THE FORMULA (X-OOC-CH2-)3-N WHEREIN EACH X IS INDEPENDENTLY HYDROGEN OR A SUITABLE CATION SUCH AS ALKALI METAL OR AMMONIUM AND TO DETERGENT COMPOSITIONS CONTAINING SAID BUILDERS. ALSO DISCLOSED ARE METHODS FOR ENHANCING THE BUILDING ACTIVITY OF SAID AMINO PHOSPHONIC ACID COMPOUNDS IN HARD WATER CLEANING SOLUTIONS PREPARED FROM WATER HAVING A HARDNESS FO UP TO 20 GRAINS PER GALLON OR MORE; AND FOR ENHANCING THE BUILDING ACTIVITY OF SAID COMPLEXING POLYMER IN CLEANING SOLUTIONS PREPARED FROM WATER HAVING A HARDNESS OF UP TO 10 GRAINS PER GALLON.
