LC/MS/MS Analysis of Alkylphenol Ethoxylates (APEO) and Alkylphenols (AP)

Introduction

In recent years, the safety concern over textiles has been on a rise in addition to the environmental and food safety issues. Harmful substances in textiles are being regulated around the world, particularly EU region. Beside regional regulations, there are also strict regulations to ensure the safety of consumers. These include the adoption of independent inspection and certification on residual standard reference such as STANDARD 100 by OEKO-TEX and chemical regulatory lists implemented by manufacturer. Alkylphenol ethoxylates (APEOs) which are commonly used as textile surfactants are restricted by REACH regulation, especially nonylphenol ethoxylates (NPEOs). NPEOs can break down to nonylphenol (NP) which can cause endocrine disruption and other health issues. “LC/MS/MS Method Package for Restricted Chemicals in Textiles” provides several types of methods for the various restricted chemicals for textiles. Here, we introduce the analysis of NPEOs and octylphenol ethoxylates (OPEOs), NP and octylphenol (OP) by using the method in them.
