Patent ID: 8338483

Claim:
A method for producing an acylglycinate of the formula (I) wherein R 1 is a linear or branched, saturated alkanoyl group having 8 to 18 carbon atoms or is a linear or branched, mono- or polyunsaturated alkenoyl group having 8 to 18 carbon atoms, and Q + is a cation selected from the alkali metal cations Li + , Na + and K + , wherein glycine is reacted with C 8 -C 18 cocoylchloride in water and in the presence of a basic alkali metal compound which provides cations Q + , but in the absence of organic solvents, at 30-35° C., and wherein the proportion of C 8 -C 18 cocoylchloride having 18 carbon atoms, based on the total amount of C 8 -C 18 cocoylchloride used, is less than 2.0% by weight.
