Detergent compositions containing n-oxide-aminocarboxylates

Abstract

Abstract BUILT SYNTHETC ORGANIC DETERGENT COMPOSITIONS COMPRISE OXIDED OF AMINOCARBOXYLATES OR AMINOCARBOXYLIC ACIDS OF THE FORMULA: (R1-CH(-OH)-CH2-N(-R2)(=O)-R2-COO-)N-X WHEREIN R1 IS AN ALIPHATIC HYDROCARBON RADICAL OF 4 TO 20 CARBON ATOMS, R2 IS A HYDROCARBON RADICAL OF 1 TO 7 CARBON ATOMS OR IS R3COOXM, R3 IS A DIVALENT ALIPHTIC OR AROMATIC HYDROCARBON RADICAL OF 1 TO 9 CARBON ATOMS, WHICH MAY BE THE SAME AS OR DIFFERENT FROM ANY OTHER R3 RADICAL IN THE COMPOUND, X IS HYDROGEN, ALKALI METAL, ALKALINE EARTH METAL, OTHER SUITABLE SALT-FORMING METAL, AMONIUM, ALKYLAMINE OR ALKANOLAMINE, WHICH MAY BE THE SAME AS OR DIFFERENT FROM ANY OTHER X IN THE FORMULA, M IS FROM 1/3 TO 1 AND N IS FROM 1 TO 3, BOTH M AND N BEING DEPENDENT ON THE VALENCE(S) OF X. IN ADDITION TO THE AMINOCARBOXYLATE, SUCH COMPOSITIONS COMPRISE AN INORGANC BUILDER SALT, SUCH AS SODIUM TRIPOLYPHOSPHATE OR POTASSIUM PYROPHOSPHATE, AND ALSO MAY INCLUDE OTHER ADJUVANT MATERIALS, SUCH AS TRISODIUM NITRILOTRIACETATE, ENZYMES, ANTI-REDESPOSITION AGENTS, BLEACHES OR BLUING AGENTS, GERMICIDES, HYDROTROPES, AUXILIARY DETERGENTS AND SOFTENING AGENTS, ETC. USUALLY, THE AMINOCARBOXYLATE COMPRISES FOR 3 TO 30% OF THE COMPOSITION AND THE INORGANIC BUILDER IS FROM 10 TO 70% THEREOF. THE PRODUCTS MADE MAY BE IN LIQUID OR SOLID FORM, AND ARE PREFERABLY EMPOLYED AS LIQUIDS OR POWDERS. THEY MAY BE UTILIZED AS WASHING-SOFTENING AGENTS IN LAUDERING OR MAY BE EMPLOYED IN PRE-SOAKING OR AFTER-SOAKING OF LAUNDRY, TO IMPROVE THE SOFTENING OF THE WASHED MATERIAL. IN SOME INSTANCES, THE AMINOCARBOXYLATE MAY BE USED WITHOUT INORGANIC BUILDER SALT, IN WHICH CASES IT NORMALLY FUNCTIONS PRIMARILY AS A SOFTENING AGENT AND IS PREFERABLY UTILIZED AFTER COMPLETION OF WASHING.
