ISO 17293-1:2014

Surface active agents — Determination of chloroacetic acid (chloroacetate) in surfactants — Part 1: HPLC method

ISO 17283-1:2014 specifies a method for the determination of monochloroacetic acid (monochloroacetate) and dichloroacetic acid (dichloroacetate) in surfactants by HPLC 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 ≤0,3 µg/ml for monochloroacetic acid and ≤0,2 µg/ml for dichloroacetic acid; the limit of quantification (LOQ) is ≤1,0 µg/ml for monochloroacetic acid and ≤0,75 µg/ml for dichloroacetic acid (using a standard solution). The LOD, at 5 g of sample weight, is ≤6 mg/kg for monochloroacetic acid and ≤4 mg/kg for dichloroacetic acid; and the LOQ is ≤20 mg/kg for monochloroacetic acid and ≤15 mg/kg for dichloroacetic acid.

ISO/DIS 17293-1
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards Draft. International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.

DRAFT INTERNATIONAL STANDARD ISO/DIS 17293-1

Surface active agents - Determination of chloroacetic acids
(chloroacetates) in surfactants-Part 1: HPLC method
1 Scope
This International Standard specifies a method for the determination of mono-chloroacetic acid (mono-
chloroacetate) and di-chloroacetic acid (di-chloroacetate) in surfactants by HPLC 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) should be ≤0,3 µg/ml for mono-chloroacetic acid and ≤0,2 µg/ml for di-
chloroacetic acid; and the limit of quantification (LOQ) should be ≤1,0 µg/ml for mono-chloroacetic acid and
≤0,75 µg/ml for di-chloroacetic acid (using a standard solution), respectively.
The LOD, at 5g of sample weight, should be ≤6 mg/kg for mono-chloroacetic acid and ≤4 mg/kg for di-
chloroacetic acid; and the LOQ should be ≤
