In recent years, the safety concern over textiles has been on the rise in addition to the environmental and food safety issues. Harmful substances in textiles are being regulated around the world, particularly the EU region. Besides the 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 references such as STANDARD 100 by OEKOTEX® and chemical regulatory lists implemented by the manufacturer. Hence, we have developed the LC/MS/MS method package for textiles which include aromatic amines, azo dyes, perfluoro compounds, alkylphenol ethoxylates, and alkylphenols.
Here, we introduce the results of the analyses of aromatic amines and azo dyes and how to effectively use the method package.
