Trolamine

Trolamine, also known as triethanolamine (TEA), is a viscous organic compound that is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. It is a colourless compound although samples may appear yellow because of impurities.

Chemical structure of Trolamine

Trolamine is characterized by the presence of an amine and three hydroxyl groups. The molecular formula of trolamine is C6H15NO3. It is a strong base due to the presence of the amine group.

Production

Trolamine is produced from the reaction of ethylene oxide with ammonia, involving an alkylation reaction. The reaction can be described as follows:

2 C2H4O + NH3 → (HOCH2CH2)2NH + H2O

Uses

Trolamine is used primarily as an emulsifier in the production of surface-active agents and detergents. It is also used in the production of cosmetics, pharmaceuticals, and in the preparation of oils and dyes. In medicine, it is used as a treatment for dry and damaged skin and in the formulation of various topical pharmaceutical products.

Safety

Trolamine is generally considered safe for use in cosmetics and topical pharmaceutical products. However, it can cause skin and eye irritation, and prolonged exposure can lead to serious eye damage.
