SCA does not endorse products with the Toxic-Free Tick, that contain MEA. The Sage Journals state that “MEA vapor, however, is highly toxic. Although DEA is readily nitrosated to form N-nitrosodiethanolamine, a known animal carcinogen, MEA has not been found to form a stable nitrosamine. Inhalation of MEA by humans is toxic.” - www.journals.sagepub.com

NICNAS not restricted for use.
WHAT IS MEA?
Causes moderate skin irritation. "Harmful if absorbed through the skin. Causes skin burns. May cause dermatitis. May cause cyanosis of the extremities."
Restricted in the US, the CIR expert review panel concluded that ethanolamines were "safe for use in cosmetics and personal care products designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin. In products intended for more prolonged contact with the skin, the concentration of TEA and DEA should not exceed 5% percent, while ethanolamine should be used only in rinse-off products."Association of Occupational and Environmental Clinics "Human immune and respiratory toxicant or allergen - strong evidence air borne products"
