This part of ISO 17293 specifies a method for the determination of monochloroacetic acid(monochloroacetate) and dichloroacetic acid (dichloroacetate) in surfactants by ion chromatographicmethod.The method applies for anionic surfactants such as alkyl (phenyl) ethoxylated carboxylate (AEC) oramphoteric surfactants such as alkyl imidazoline carboxylate, alkyl dimethyl betaine, and fatty acetylpropyl dimethyl betaine.The limit of detection (LOD) is ≤0,01 μg/ml for monochloroacetic acid and ≤0,05 μg/ml for dichloroaceticacid; and the limit of quantification (LOQ) is ≤0,1 μg/ml for each standard (using a standard solution).The LOD, at 1 g of sample weight, is ≤1 mg/kg for monochloroacetic acid and ≤5 mg/kg for dichloroaceticacid; and the LOQ is ≤10 mg/kg for each acid.
