Triethanolamine and TEA-Containing Ingredients
Expert Panel for Cosmetic Ingredient Safety
The safety of TEA and TEA-containing ingredients have been assessed on several occasions by the Expert Panel for Cosmetic Ingredient Safety (Expert Panel).
In 1983, the Expert Panel evaluated available scientific data and that TEA was safe for use in cosmetics and personal care products designed for discontinuous, brief use followed by thorough rinsing from the skin’s surface. In products intended for prolonged contact with the skin, the concentration of TEA should not exceed 5%. Triethanolamine should not be used in products containing N-nitrosating agents to prevent the formation of possibly carcinogenic nitrosamines.
In 2013, the Expert Panel reviewed the scientific data supporting the safety of TEA and 31 related TEA-containing ingredients and that they are safe in the present practices of use and concentration when formulated to be non-irritating. The panel was concerned with the levels of free diethanolamine that could be present as an impurity in TEA or TEA containing ingredients and cautioned that ingredients should not be used in cosmetics products in which N-nitroso compounds can be formed. This opinion superseded the one from 1983.
