DEA-cetyl phosphate other DEA-containing ingredients include DEA oleth-3 phosphate, Lauramide DEA, monoethanolamine MEA, Myristamide DEA, Oleamide DEA, Stearamide MEA, TEA-lauryl sulfate and triethanolaminem. Used as emulsifiers or foaming agents, DEA is readily absorbed through the skin, accumulating in organs such as brain, liver and kidneys. DEA interacts with nitrite preservatives or contaminants in cosmetics to form nitrosodiethanolamine (NDELA), a proven carcinogen that is readily absorbed through the skin. The European Union and European industry have reduced or eliminated DEA and NDELA from their products.
