Leather - Determination of ethoxylated alkylphenols (APEO) - Part 1: Direct method (ISO/FDIS 18218-1:2023)

This document is a method for determining ethoxylated alkylphenols (APEO) [nonyphenol ethoxylate (NPEOn, where 2 ≤ n ≤ 16) and octylphenol ethoxylate (OPEOn, where 2 ≤ n ≤ 16)] in leather. This direct method is especially suitable when a larger number of leather samples are to be checked for the presence of ethoxylated alkylphenols.
This method requires the use of liquid chromatography (LC) with a triple quadrupole mass spectrometer (MS/MS) to identify and quantify the ethoxylated alkylphenols.
NOTE 1        In the leather industry, the most commonly used ethoxylated alkylphenol is the NPEO, with an average of 9 EO. It has an optimum cloud point in water for the typical leather processing temperatures of 40 °C to 55 °C.
NOTE 2        This document and ISO 18218-2 use different solvents for the extraction of the ethoxylated alkylphenols from leather. Consequently, the two analytical methods are expected to give similar trends but not necessarily the same absolute result for the ethoxylated alkylphenol content in leather.

Leder - Bestimmung von ethoxylierten Alkylphenolen (APEO) - Teil 1: Direktes Verfahren (ISO/FDIS 18218‑1:2023)

Dieses Dokument legt ein Verfahren zur Bestimmung von ethoxylierten Alkylphenolen (APEO) [Nonylphenolethoxylat (NPEOn, wobei 2 ≤ n ≤ 16) und Octylphenolethoxylat [OPEOn, wobei 2 ≤ n ≤ 16)] in Leder fest. Dieses direkte Verfahren ist besonders geeignet, wenn eine größere Anzahl von Lederproben auf die Anwesenheit von ethoxylierten Alkylphenolen zu überprüfen ist.
Dieses Verfahren erfordert die Anwendung der Flüssigkeitschromatographie (LC) mit einem Triple-Quadrupol-Massenspektrometer (MS/MS), um ethoxylierte Alkylphenole zu identifizieren und quantitativ zu bestimmen.
ANMERKUNG 1   Das in der Lederindustrie am häufigsten verwendete ethoxylierte Alkylphenol ist NPEO mit einem Mittelwert von 9 EO. Es hat bei den typischen Verarbeitungstemperaturen von Leder von 40 °C bis 55 °C einen optimalen Trübungspunkt in Wasser.
ANMERKUNG 2   Dies Dokument und ISO 18218 2 verwenden verschiedene Lösemittel zur Extraktion der ethoxylierten Alkylphenole aus Leder. Für die beiden analytischen Verfahren wird erwartet, dass sie für den Gehalt ethoxylierter Alkylphenole in Leder konsequenterweise ähnliche Tendenzen, jedoch nicht zwangsläufig das absolut identische Ergebnis liefern.

Cuir - Détermination des alkylphénols éthoxylés (APEO) - Partie 1: Méthode directe (ISO/FDIS 18218-1:2023)

Le présent document spécifie une méthode de détermination des alkylphénols éthoxylés (APEO) [éthoxylate de nonylphénol (NPEOn, où 2 ≤ n ≤ 16) et éthoxylate d’octylphénol (OPEOn, où 2 ≤ n ≤ 16)] dans le cuir. Cette méthode d’analyse directe convient particulièrement lorsque les alkylphénols éthoxylés doivent être dosés sur un grand nombre d’échantillons de cuir.
L’analyse est effectuée par chromatographie en phase liquide (CL) couplée à la spectrométrie de masse en tandem avec un analyseur à triple quadripôle (SM/SM), afin d’identifier et de quantifier les alkylphénols éthoxylés.
NOTE 1        Parmi les alkylphénols éthoxylés, celui qui est le plus utilisé dans l’industrie du cuir est le NPEO, qui contient en moyenne 9 groupes éthoxy. La température de trouble dans l’eau de cette substance est optimale compte tenu des températures généralement utilisées pour le traitement du cuir, qui sont comprises entre 40 °C et 55 °C.
NOTE 2        Le présent document et l’ISO 18218-2 utilisent différents solvants pour l’extraction des alkylphénols éthoxylés du cuir. Par conséquent, on peut s’attendre à ce que les résultats obtenus en suivant l’une des deux méthodes analytiques soient comparables à ceux obtenus en suivant la seconde méthode, mais non nécessairement identiques, pour ce qui concerne la teneur en alkylphénols éthoxylés dans le cuir.

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).

assessment, as well as information about ISO's adherence to the WTO principles in the Technical

ISO 18218-1 was prepared by the Chemical Test Commission of the International Union of Leather

Technologists and Chemists Societies (IUC Commission, IULTCS) in collaboration with the European

Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of

which is held by UNI, in accordance with the Agreement on technical cooperation between ISO and CEN

(Vienna Agreement).

IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to

further the advancement of leather science and technology. IULTCS has three Commissions, which

are responsible for establishing international methods for the sampling and testing of leather. ISO

recognizes IULTCS as an international standardizing body for the preparation of test methods for

leather.

This second edition cancels and replaces the first edition (ISO 18218-1:2015), which has been technically

revised as follows:
— a new clause 3 has been added, the following clauses have been re-numbered;
— the Note in clause 8.1 has been deleted.

Introduction

Nonylphenol ethoxylate belongs to the non-ionic surfactants. The biodegradation of nonylphenol

ethoxylate releases the persistent pollutant, the branched nonylphenol. Nonylphenol is a hormonal

acting substance that is toxic for waterborne organisms and many other organisms. For this reason the

release of nonylphenol ethoxylate into the environment should be avoided.

In 2003 the European Directive 2003/53/EC restricted the sale and use of nonylphenol and nonylphenol

ethoxylate in product preparations for industries with discharges to waste water. Preparations

containing concentrations equal or higher than than 0,1 % of nonylphenol ethoxylate or nonylphenol

were forbidden. This Directive is included as part of the EU Regulation 1907/2006 (REACH).

No detailed composition of the chemical substance nonylphenol ethoxylate can be given, it is assigned

the general structural formula:
(C alkyl chain, branched or linear)–Ph–[OCH CH ] –OH (with Ph = phenyl, n ≥ 1 ).
9 2 2 n

To cover the group of ethoxylates of 4-nonylphenol, branched and linear, the European Chemical

Agency (ECHA) has assigned the substance the following definition: 4-nonylphenol, branched and linear,

ethoxylated [substances with a linear and/or branched alkyl chain with a carbon number of 9 covalently

bound in position 4 to phenol, ethoxylated covering UVCB and well-defined substances, polymers and

homologues, which include any of the individual isomers and/or combinations thereof].
