Production of amidocarboxylic acid phenyl esters (I) comprises adding an inorganic acid halide to a mixture of an amidocarboxylic acid or its alkali metal salt and a substituted phenol or its salt. Production of amidocarboxylic acid phenyl esters of formula (I) comprises adding an inorganic acid halide to a mixture of compounds of formula (II) and (III): A = -CONR<2>- or -NR<2>CO-; R<1> = 1-26C alkyl, alkenyl, alkynyl or cycloalkyl or 6-14C aryl or alkaryl; R<2> = H, 1-26C alkyl, alkenyl, alkynyl or cycloalkyl or 6-14C aryl or alkaryl; R<3>, R<4> = H or 1-10C alkyl, alkenyl, alkynyl or cycloalkyl; R<5> = H, halogen or 1-6C alkyl, alkenyl, alkynyl, cycloalkyl or alkoxy; n = 1-10; X = SO3M, OSO3M, (CH2)mSO3M, (CH2)mOSO3M, COOM or N(R<6>)3Y; M = H or alkali metal; R<6> = 1-6C alkyl or 4-6C cycloalkyl; Y = halogen; m = 1 or 2. An Independent claim is also included for a detergent composition containing (I) thus prepared.
