Namely
Triethanolamine, or more commonly referred to as TEA, is a basic tertiary amine. It is often used as a pH adjuster or to thicken cosmetic formulas. Its manufacture results from the reaction of ethylene oxide (very toxic) with ammonia (also toxic).
In the presence of nitrite, TEA forms nitrosamines known to be carcinogenic. Nevertheless, we must imagine that the risk remains very low in a bathroom. However, beyond this aspect, many studies (including RTC) seem to indicate that TEA is toxic to the skin, the immune system and the respiratory tract in humans. One or more animal studies have shown effects on the sense organs at very low doses, especially when used around the mouth, eyes and lips, and one or more in vitro cell tests. mammal showed positive mutation results

Its functions (INCI)
- pH regulator : Stabilises the pH of cosmetics
- Emulsifying : Promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil)
- Masking : Reduces or inhibits the odor or basic taste of the product
- Surfactant : Reduces the surface tension of cosmetics and contributes to the even distribution of the product when it is used
This ingredient is present in 5.16% of cosmetics.
