Cosmetics. Analytical methods. Nitrosamines. Detection and determination of N-nitrosodiethanolamine (NDELA) in cosmetics by HPLC, post-column photolysis and derivatization Ingestion-build-141043 Typical inherent flow characteristics1 Scope This International Standard describes a method for the detection and quantification of N nitrosodiethanolamine (NDELA) in cosmetics and raw materials used in cosmetics by high performance liquid chromatography (HPLC) coupled with post column photolysis and derivatization. This method is not applicable to the detection and or quantification of nitrosamines other than NDELA, nor to the detection and or quantification of NDELA in products other
