Ethanolamine and its derivatives such as diethanolamine (DEA) and triethanolamine (TEA) are used in many skincare, cosmetic and personal care products. They play numerous functions such as neutralizers, surfactants (foaming agents, emulsifiers) or even hair fixatives.
However, these ingredients may also create issues.
For instance, DEA can interact with other ingredients present in the cosmetic formulation called N-nitroso and form nitrosamines, which are believed to be carcinogens. Experiments in animals have shown the carcinogenicity of nitrosamines. Although its carcinogenicity is still uncertain in humans, it is probable, and the use of ethanolamine in cosmetic formulations is thus increasingly discouraged.
