Triethanolamine (TEA 85%) serves as a highly versatile and water-soluble chemical compound that supports a broad range of industrial processes. Specifically, TEA 85% represents a commercial-grade formulation that combines primarily triethanolamine with a smaller percentage of diethanolamine. In some cases, manufacturers also include water to adjust the properties based on application needs. Thanks to its multifunctional nature, this alkanolamine delivers significant advantages across several industries. For example, companies rely on TEA 85% in chemical manufacturing, gas sweetening, textile finishing, metalworking, and personal care product formulation. Additionally, its performance in surfactant systems and agricultural solutions makes it an essential ingredient for both industrial and commercial use.
What is Triethanolamine (TEA 85%)?
Triethanolamine (TEA) is a clear, viscous liquid with a mildly ammoniacal odor. Its chemical formula is (HOCH₂CH₂)₃N, and it belongs to the alkanolamine family. The compound has a molecular weight of 149.19 and a CAS number of 102-71-6.
TEA 85%, also known as TEA B85 LFG (Low Freeze Grade), is a special aqueous blend designed to remain fluid at lower temperatures. While standard triethanolamine may freeze at around 18°C, this low-freeze variant has a freeze point of approximately -9°C, making it suitable for colder climates and specialized storage conditions.

Applications of Triethanolamine (TEA 85%)
1. Gas Sweetening
TEA 85% is widely used in natural gas treatment processes, particularly for acid gas removal. As part of a class of amines used for gas sweetening, TEA reacts with hydrogen sulfide (H₂S) and carbon dioxide (CO₂), helping to purify sour gas. It is often used alongside MEA, DEA, DIPA, and MDEA for efficient gas processing and lower energy consumption.
2. Textile Industry
In textiles, TEA functions as a softening agent. It helps in modifying the surface of fabrics, making them smoother and more pleasant to the touch.
3. Dry Cleaning
In the dry-cleaning industry, TEA 85% functions as a water-compatible additive that offers multiple benefits. As a result, it actively prevents corrosion and minimizes static electricity. Consequently, it extends the lifespan of garments and equipment while improving overall safety and performance during the cleaning process.
4. Metalworking and Welding
TEA is used in lubricant sprays for welding and cutting applications. It protects metal surfaces from corrosion and neutralizes acidity caused by environmental moisture.
5. Cosmetics and Personal Care
A common ingredient in shampoos, creams, and lotions, triethanolamine is combined with fatty acids (like stearic acid) to form emulsifiers that stabilize cosmetic formulations and generate foam in products such as cleansers.
6. Additional Industrial Uses
TEA 85% also finds applications in:
Adhesives
Agriculture (fertilizer formulations)
Cement grinding aids
Photographic chemicals
Rubber processing
Surfactant production
