Aminocarboxylate chelating agents are described having generic formulas selected from the group consisting of (A) and (B) wherein Rthrough Rare as further defined herein. Compositions containing at least one of these aminocarboxylate chelating agents are also described. The compositions are useful for example as detergent compositions for laundering clothing and compositions for cleaning dishes, in particular cleaning dishes using automatic dish washing devices.

Aminocarboxylate chelating agents and detergent compositions containing them

One aspect of the present invention is a polyoxyalkylene ester composition comprising the reaction product of a polyoxyalkylated alcohol or polyol reactant and an acyl donor wherein the ester has greater than about 85 weight percent of a fully acylated polyoxyalkylene ester, less than about 15 percent of a partially acylated polyoxyalkylene ester, less than about 5 parts per million 1,4-dioxane and an acid number of less than about 20. Another aspect of the invention is a process for making the polyoxyalkylene ester composition that includes the steps of contacting a reaction mixture of an polyoxyalkylated alcohol or polyol reactant and an acyl donor reactant in a reactor and in the presence of an enzymatic catalyst under esterification conditions and recovering the polyoxyalkylene ester.
