Leather. Determination of ethoxylated alkylphenols - Indirect method1 Scope This document specifies a method for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather and process auxiliaries. The analysis is based on high performance liquid chromatography (HPLC) or gas chromatography mass spectrometry (GC MS). The analysis of the alkylphenol ethoxylate is made by cleaving the alkylphenol ethoxylate and measuring the released
