Assay of suntan lotions for the carcinogenic, non-volatile N-nitrosamine N-nitrosodiethanolamine.
N-nitrosodiethanolamine (NDELA) is a carcinogenic, non-volatile nitrosamine that has been shown to pass readily through the skin of animals and humans. It has often been found as a contaminant in cosmetics. Twenty different suntan lotions, available in Israel, both liquids and creams, were analyzed for NDELA content. Most products contained undetectable or trace levels, but 3 were found to be contaminated with as much as 27 ppb of the nitrosamine. Continual use of such products, especially by small children and infants, may significantly increase their exposure to NDELA.
