Abstract: Process for manufacturing a formulation of a chelating agent according to general formula (I): R1-CH(COOX1)-N(CH2COOX1)2, wherein R1 is selected from C1-C4-alkyl, linear or branched, phenyl, benzyl, CH2OH, and CH2CH2COOX1, X1 is (ΜxΗ1-x), M being selected from alkali metal, x is in the range of from 0.6 to 1, said formulation comprising in the range of from 0.01 to 20% by weight of water, and at least one organic solvent selected from alkanols with a boiling point at normal pressure that is higher than the boiling point of water, from alkandiols, alkantriols and polyols and mixtures of at least two of the foregoing, said process comprising the following steps: (a) providing an aqueous solution of chelating agent according to general formula (I), (b) adding said organic solvent and (c) removing the water completely or the majority of the water by distillation.
