What Is Triethanolamine?
Triethanolamine (TEA) is a tertiary amino compoundi An amine in which nitrogen atoms are bonded to three carbon atoms to make ammonia. and triol (a compound containing three hydroxyl groups) (1). It is a colorless, oily liquid, denser than water, and smells slightly like ammonia as it has nitrogen in the center.
Did You Know?Triethanolamine is commonly used in cosmetic products as a pH adjusting agent, emulsion stabilizer, and surfactanti A detergent agent added to soaps, shampoos, and other products to cleanse a person or object or to reduce the surface tension of water. .

Let’s find out in the next section.
Is Triethanolamine Safe For Your Skin?
Yes, triethanolamine is considered safe for use in both skin and hair care products. Many concerns are raised on triethanolamine’s toxicity and its safety as a skin care ingredient. These concerns stem from the fact that triethanolamine results from a reaction of ammonia with N-nitrosatingi A reaction in which organic amino compounds mix with nitrates to form nitrosamines. ingredients to create nitrosamines, which were thought to be carcinogens.
However, the levels of N-nitrosating ingredients in skin care products are highly regulated, so the interaction of the two ingredients to form carcinogenici An element, ingredient, or chemical that has potential cancer-causing properties. compounds is relatively low. Also, most of the products must comply with the guidelines set by the Cosmetic Ingredient Review Expert Panel, which bars the use of TEA in any products in which N-nitroso compounds can form (2). The panel concluded that TEA and TEA-related ingredients are safe when formulated to be non-irritating to the skin.
Hence, you need not panic and banish all TEA-containing products from your skin care routine. This ingredient does not have any skin benefits. However, it can help improve the efficiency of the cosmetic formulations of the products.
What Are The Benefits Of Triethanolamine?
Here are some benefits of using triethanolamine in cosmetics:
1. Balances The pH Levels
One of the most important uses of triethanolamine is balancing the pH of cosmetic formulations. It is known to neutralize higher and lower pH and reduce the acidity and alkalinityi The capacity of a water body to neutralize bases and acids to obtain a balanced pH level. of any product. Products with neutral pH levels do not irritate the skin.
2. Excellent Emulsifier
Triethanolamine is also said to help in the emulsification of various ingredients, which is one of the primary reasons it is used in creams and other product formulations.
Emulsification is the process of mixing two immiscible liquids, mostly an oil and non-oil liquid, to form a more homogenous product. For this process, you need a chemical that helps in the process by holding both molecules together.
Triethanolamine can aid this process and prevent oils and other liquids from separating, giving the product an even consistency.
3. Thickening Agent
Another reason you find triethanolamine in lotions and creams is its benefit as a thickening agent (3). Many formulations (like creams, moisturizers and conditioners) require thickeners to get the ideal consistency.
