Triethanolamine (TEA) Chemical Compatibility

Storing Triethanolamine? Start Here

Triethanolamine, often called TEA, is a versatile chemical used in various industries, from cement production to cosmetics. If you're dealing with cement grinding aids or personal care products, you're likely familiar with its benefits. However, TEA is a bit tricky to handle due to its syrupy nature, especially in cooler temperatures, and its tendency to change color when exposed to air. Let's make sure you store it right to keep your operations smooth and efficient.

Can you store it in a poly tank?

Yes, you can store triethanolamine in a polyethylene tank. High-density polyethylene (HDPE) and cross-linked polyethylene (XLPE) tanks are industry-standard for all concentrations of TEA, including the neat 85%+. These materials are compatible and reliable for long-term storage.

Watch out for viscosity issues

Triethanolamine is thick and syrupy, which can make transferring it a challenge, especially when temperatures drop below 60°F. Consider using heat tracing to keep the fluid flowing smoothly during transfers.

The safety that actually matters

• Use appropriate gaskets: Match gaskets to the manufacturer chart to ensure compatibility.
• Avoid aluminum and copper: These metals can corrode over time when in contact with TEA.
• Prevent air exposure: Use a nitrogen blanket if possible to keep TEA from discoloring.

Common questions

Is triethanolamine safe to handle?

It can irritate the skin and eyes, so use protective gear when handling.

Does TEA require special storage conditions?

Yes, it should be kept in compatible tanks and may need heating to manage viscosity.

What materials should I avoid with TEA?

Avoid using aluminum and copper, as they can corrode when in contact with TEA.
