TEA Triethanolamine 99% is a high-purity, viscous organic compound that functions as both a tertiary amine and a triol. It is widely used across industries as a pH adjuster, emulsifier, and corrosion inhibitor.

Key Specifications & Properties

TEA 99 typically exhibits the following characteristics:

Appearance: A colorless to pale yellow liquid with a mild, ammonia-like odor.

Purity: Minimum 99% purity, often containing trace amounts of diethanolamine and ethanolamine.

Freezing Point: Approximately 70°F (21°C); it freezes easily and may require heating for use in cooler environments.

Solubility: Completely soluble in water.

pH: Approximately 11 in a 25% aqueous solution.

Common Applications

TEA 99 is a versatile "building block" chemical used in various sectors: 

Personal Care: Stabilizes creams, lotions, and gels; used in shampoos, shaving foams, and sunscreens as a neutralizing agent.

Industrial Cleaning: Acts as a surfactant and pH regulator in liquid laundry detergents and multi-purpose cleaners.

Metalworking: Used in cutting fluids and lubricants to prevent corrosion and improve efficiency.

Construction: Serves as a cement grinding aid to prevent powder agglomeration in ball mills.

Chemical Manufacturing: Acts as a catalyst in urethane foam production and an intermediate for agricultural chemicals.

Safety & Handling

Handling: Avoid contact with skin and eyes; use with adequate ventilation.

Reactivity: Do not use with sodium nitrite or other nitrosating agents, as this can form suspected cancer-causing nitrosamines.

Corrosion: May be corrosive to aluminum, copper, and zinc alloys, especially when wet or at elevated temperatures.

Storage: Store in a cool, dry place, ideally under an oxygen-free nitrogen atmosphere to prevent oxidation and yellowing.
