1 Scope This standard specifies the determination method of alkylphenols and alkylphenol polyethoxylates in textile dyeing and finishing auxiliaries. This standard is applicable to the determination of alkylphenol and alkylphenol polyethoxylate in textile dyeing and finishing auxiliaries with LC/MS method. 2 Normative References The following clauses in the document constitute provisions of this standard through quoting it. The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. For undated references, the latest edition applies.

Common substances of this class are octylphenol (C8H17-C6H4-OH, referred to as OP) and nonylphenol (C9H19-C5H4-OH, referred to as NP) 3.2 alkylphenol polyethoxylates, referred to as APEO the molecular structure formula of alkylphenol polyethoxylates is: R-C6H4-(OC2H4)nOH. Common substances of this class are octylphenol ethoxylate [C8H17-C6H4-(OC2H4)nOH], referred to as OPEO and nonylphenol ethoxylate [C9H19-C6H4-(OC2H4)nOH], referred to as NPEO Alkylphenol polyethoxylates can be used as the surfactant in textile dyeing and finishing auxiliaries, and alkylphenols are degradation products of alkylphenol polyethoxylates 4 Determination Method
