Cosmetics. Analytical methods. Nitrosamines: Detection and determination of N-nitrosodiethanolamine (NDELA) in cosmetics by HPLC-MS-MS Ingestion-build-48348 Gas cylinder manufacturers and welders1 Scope This International Standard describes a method for the detection and quantification of N nitrosodiethanolamine (NDELA) in cosmetics and raw materials used in cosmetics. 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 than cosmetics or raw materials used in cosmetics. If a product has a possibility of either NDELA
