Why is triethanolamine not good for skin?
One reason you may not have heard of triethanolamine is partly due to the lack of benefits it provides to the skin , but also due to the low concentrations present in the product.
What is the smell of triethanolamine?
Triethanolamine is a compound with a slight ammonia smell; think of hair dyes. The thick, colorless liquid helps reduce the surface tension of products. It also helps to mix oil and water-based products to create a smooth, stable formulation. Triethanolamine is also involved in controlling the pH of products, making it an excellent ingredient ...
Does triethanolamine react with diethanolamine?
The N-nitrosating ingredients that can interact with triethanolamine in a formulation are highly regulated, making the likelihood of the formation of carcinogens reasonably low. This reaction only occurs with diethanolamine and N-nitrosating ingredients, such as nitrates. Given that triethanolamine breaks down to produce diethanolamine in formulations, any product with triethanolamine needs to comply with the guidelines to omit N-nitrosating ingredients.

Romanowski says that the ingredient is not dangerous to use at cosmetic levels and is safe when delivered from a standard cosmetic product. "Toxicology experts have reviewed the safety testing and data on TEA and have concluded that the products on the market today and the levels of TEA used are not unsafe," he says. "There is no evidence of a problem with longterm exposure. This is just standard chemical fear mongering." Schultz adds, "There is no known link to cancer."
What is triethanolamine used for?
Triethanolamine is used primarily in making surfactants, such as for em ulsifier. It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in water. Triethanolammonium salts in some cases are more soluble than salts of alkali metals that might be used otherwise, and results in less alkaline products than would from using alkali metal hydroxides to form the salt. Some common products in which triethanolamine is found are sunscreen lotions, liquid laundry detergents, dishwashing liquids, general cleaners, hand sanitizers, polishes, metalworking fluids, paints, shaving cream and printing inks.

Systemic and respiratory tract (RT) toxicity was analyzed for 28 days in a nose specific inhalation 2008 study in Wistar rats; TEOA seems to be less potent in regard to systemic toxicity and RT irritancy than diethanolamine (DEA). Exposure to TEOA resulted in focal inflammation, starting in single male animals from 20 mg/m 3 concentrations.
