Triethanolamine Cosmetic Grade Tank Selection

Storing Triethanolamine? Start Here

If you're in the business of making cosmetics like lotions, shampoos, or soaps, you might be using Triethanolamine (TEA). It's a common ingredient that helps adjust pH and works as an emulsifier. When it comes to storing this chemical, you need to know the right type of tank to use to keep your operations running smoothly and safely.

Can you store it in a poly tank?

Yes, you can store Triethanolamine in a polyethylene (poly) tank. HDPE or XLPE rotomolded tanks are standard for storing TEA at room temperature, especially in smaller cosmetic manufacturing settings. However, for operations that follow strict GMP guidelines, 316L stainless steel tanks are preferred.

Watch out for moisture and color changes

Triethanolamine is hygroscopic, meaning it absorbs moisture from the air, which can lead to a carbonate haze. It can also yellow over time if exposed to air or iron. Keeping it sealed and using the right materials can help maintain its quality.

The safety that actually matters

• Use tanks made from HDPE or XLPE for standard storage.
• For GMP operations, consider 316L stainless steel tanks.
• Ensure tanks are kept sealed to prevent moisture absorption.
• Regularly check for color changes due to air or iron exposure.

Common questions

Is polyethylene suitable for storing TEA?

Yes, HDPE and XLPE tanks are suitable for storing TEA at ambient temperatures.

What gasket material should I use?

Viton gaskets are recommended for TEA storage, but always check with the manufacturer's compatibility chart.

Does TEA require special handling?

TEA is mildly alkaline and should be stored in sealed containers to prevent moisture absorption and color changes.
