Triethanolamine (TEA) 99%

Whatsapp Order

Triethanolamine (TEA) 99% is a high-purity grade of triethanolamine, a viscous, colorless to pale yellow liquid with a mild ammonia-like odor. This high-concentration grade is widely used in cosmetics, pharmaceuticals, and industrial applications where superior purity is required. It functions primarily as a pH adjuster, emulsifier, surfactant, and corrosion inhibitor. TEA 99% is essential in neutralizing fatty acids to form soaps and stabilizing emulsions, enabling improved texture and stability in personal care products, as well as in chemical manufacturing processes demanding high-quality inputs.

 

Description

Primary Uses
Cosmetics and Personal Care: Used as a pH adjuster, emulsifier, and surfactant in creams, lotions, shampoos, soaps, and other personal care products requiring high purity to avoid impurities that affect product safety and stability.

Pharmaceutical Formulations: Serves as a pH regulator and emulsifying agent in topical ointments, creams, and medicinal solutions, where high-grade materials are crucial.

Industrial Applications: Functions as a corrosion inhibitor and neutralizing agent in metalworking fluids, cooling towers, boilers, and other water treatment systems that demand high purity to minimize contamination.

Chemical Manufacturing: Utilized in the synthesis of surfactants, detergents, textile processing chemicals, and other specialty chemicals requiring a high purity raw material.

Secondary Uses
Agriculture: Incorporated in pesticide formulations as a neutralizing and dispersing agent to enhance performance.

Paints and Coatings: Acts as a neutralizer and stabilizer in water-based paints and coatings with strict purity standards.

Printing Industry: Used as a pH regulator and emulsifier in ink formulations requiring minimal impurities.

Gas Treatment: Applied in scrubbing acidic gases such as CO2 and H2S, where purity impacts efficiency and corrosion control.
