Abstract: The present invention is directed towards a process for manufacturing a complexing agent, said process comprising the steps of (a) Providing a nitrile according to general formula (I a) or (I b) With M being selected from alkali metal and hydrogen and combinations thereof, (b) Saponification with a total alkali amount of 2.5 to 2.9 mol of alkali metal hydroxide per mole of nitrile according to general formula (I a) or (I b), respectively, and a pH value in the range of from 9.5 to 11.5 at the end of step (b), (c) Adding an amount of alkali metal hydroxide so that the total alkali content is 2.9 to 3.15 moles per mole nitrile according to general formula (I a) or (I b), respectively, and (d) Allowing further conversion.

Abstract: The present application is related to a container made of a polymer and containing a single unit dose of a detergent composition. The detergent composition contains at least two complexing agents (A) dissolved in an aqueous medium. The complexing agents (A) are (A1) at least one alkali metal salt of methyl glycine diacetic acid (MGDA), and (A2) at least one alkali metal salt of glutamic acid diacetic acid (GLDA). The complexing agents (A1) and (A2) are partially neutralized with alkali and the weight ratio of (A1) and (A2) ranges from 1:9 to 9:1. The aqueous medium contains at least 25% by weight of water relative to the entire liquid phase.
