Triethanolamine (TEA) is an organic compound that exhibits specific chemical properties due to the presence of amine and alcohol groups. This viscous chemical is produced by the reaction between ammonia and ethylene oxide. Its production process is normally slow, but the presence of water can increase the reaction rate. This reaction is also possible without the need for water and using ion exchange resins. Triethanolamine is used in many industries, including the production of detergents, cosmetics, and hygiene products, due to its special structure.

Environmental impact of TEA
Triethanolamine, as a water-soluble chemical, can affect water quality if released into the environment. In high concentrations, it may be toxic to aquatic life and may harm aquatic ecosystems. Therefore, its improper disposal and release into water sources must be carefully controlled to prevent environmental contamination.
Safety Measures and Regulations for Handling TEA
When working with TEA, it is essential to use personal protective equipment such as gloves, safety glasses, and a mask to prevent skin and eye contact. The chemical should be stored in a dry, cool environment away from direct sunlight and incompatible materials. In case of leakage or spillage, it should be cleaned up immediately and prevented from entering sewers or water sources. It is also very important to comply with local and international regulations for its transportation and disposal.
