Long-chain N-nitroso-N-methylalkylamines in commercial cosmetics, light-duty dishwashing liquids and household cleaning preparations.


A method for the determination of long-chain N-nitroso-N-methylalkylamines in a range of commercial cosmetic and cleaning emulsions is described. The clean-up consists of solid-phase extraction and column chromatography. N-Nitroso-N-methyldodecylamine, N-nitroso-N-methyltetradecylamine and N-nitroso-N-methylhexadecylamine are detected by gas-liquid… (More)
