Triethanolamine

Triethanolamine (TEA) is used to stabilize emulsions and correct pH in various industrial, technical and cosmetic systems. Due to its molecular structure containing three hydroxyl groups, TEA provides good solubility in water and interacts with lipophilic components.

Chemical structure and synthesis

The triethanolamine molecule has the following formula:

N(CH2​CH2​OH)3​

Synthesis is usually carried out by esterification of ethylene oxide with ammonia. The resulting product is characterized by the presence of three hydroxyl groups, which ensures its amphiphilic properties and high ability to regulate pH.

Physico-chemical properties

• Solubility: It is highly soluble in water due to its many polar groups.

• Alkalinity: It has a slightly alkaline character, which allows it to be used to neutralize acids.

• Amphiphilicity: It is able to interact with both water and oil components, contributing to the formation of stable emulsions.

Application

• Cosmetics industry: It is used in creams, lotions, shampoos and other emulsion systems.

• Pharmaceuticals: It is used as a component of the stabilization of dosage forms and in preparations with controlled pH.

• Chemical production: It is used as a raw material for the synthesis of surfactants, as well as in various softening and emulsification processes.

Conclusion

Triethanolamine occupies an important place in modern technologies for creating emulsions and stabilized systems. Its amphiphilic and pH buffering properties make it an indispensable component in cosmetics, pharmaceuticals and other industries where precise pH regulation and stability of emulsions are required.
