MEA (monoethanalomine), DEA (diethanolamine), TEA(triethanolamine)

Can react with nitrites to form carcinogenic nitrosamines. Nitrites may be present as preservatives or contaminants in other products, or in some water sources. These ethoxylated alcohols may also be contaminated with 1,4-dioxane, a possible human carcinogen that is persistent in the environment. 1,4-dioxane can be removed during the manufacturing process, but there is no easy way to know if that has occured. DEA is a mild skin and severe eye irritant. MEA is known to induce asthma in workplace settings.
