DEA, TEA, MEA chemicals found in products as their main ingredients
DEA (Diethanolamine), TEA (Tea, triethanolamine), MEA(Cocamide DEA; Laurimide DEA; Linoleamide DEA, Oleamide DEA) (solvent, emulsifier, wetting agent)
Found in most things--shampoos, conditioners, lotions, shaving gels, bubble bath, skin creams, etc.
US Dept of Health and Human Services' National Toxicology Program, 1997 (NTP TR 478):
· clear evidence of carcinogenic activity
"Diethanolamine was selected for evaluation because its large-scale production and pattern of use indicate potential for widespread human exposure."
NTP requested that the FDA require a warning label on all formulations containing cocamamide DEA
1979--FDA warned that 42% of all cosmetics were found contaminated with NDEA (N-nitrosodiethanolamine) which is formed when DEA reacts with nitrosating agents (may be through actual addition of nitrite as a preservative, through degradation of other ingredients or by exposure to air)
1991--FDA found that 27 of 29 of the products they tested were still contaminated
No way of telling if NDEA has been formed...so avoid all DEA, TEA, MEA--in 1996, the Cosmetics, Toiletries, and Fragrance Association stated that "These chemicals...should not be used as ingredients in cosmetic products."
