This International Standard specifies a method of analysis for the determination of the chelating agent content of detergent compositions and soaps containing not more than 2 % (m/m) of chelating agent.
Ethylenediaminetetraacetic acid (EDTA) is one of the most widely used chelating agents and the method has been designed principally for determining this compound and its salts. Before determining other chelating agents, or determining ethylenediaminetetraacetic acid in the presence of other chelating agents, the applicability of the method should be confirmed.
