Surface active agents — Determination of chloroacetic acid (chloroacetate) in surfactants — Part 2: Ionic chromatographic method
ISO 17293-2:2014 specifies a method for the determination of monochloroacetic acid (monochloroacetate) and dichloroacetic acid (dichloroacetate) in surfactants by ion chromatographic method. The method applies for anionic surfactants such as alkyl (phenyl) ethoxylated carboxylate (AEC) or amphoteric surfactants such as alkyl imidazoline carboxylate, alkyl dimethyl betaine, and fatty acetyl propyl dimethyl betaine. The limit of detection (LOD) is ≤0,01 µg/ml for monochloroacetic acid and ≤0,05 µg/ml for dichloroacetic acid; 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 dichloroacetic acid; and the LOQ is ≤10 mg/kg for each acid.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
