Witch Hazel Pharmaceutical USP (Hamamelis Water USP Steam Distillate with 14% Ethanol Astringent) Storage

Storing Witch Hazel USP? Start Here

If you're dealing with Witch Hazel USP, you're handling a clear, slightly aromatic liquid that's used in many skincare and medicinal products. It contains about 14% ethanol, which gives it its mild antiseptic properties. This makes it a bit flammable, so you'll want to store it safely. Whether you're in the business of making hemorrhoidal wipes or skin toners, knowing how to store it properly is key.

Can you store it in a poly tank?

Yes, you can store Witch Hazel USP in a polyethylene (poly) tank. High-density polyethylene (HDPE) is fully compatible with the modest pH and alcohol content of witch hazel. It's a good choice for bulk storage, whether you're keeping it outside or using it as a feedstock for manufacturing.

Watch out for flammability

One key issue to be aware of is the flammability of Witch Hazel USP due to its ethanol content. Classified as a Class IB flammable liquid, it's important to control ignition sources around storage areas. Proper ventilation and grounding of tanks can help mitigate risks.

The safety that actually matters

• Ensure tanks are grounded to prevent static discharge.
• Store away from heat and ignition sources.
• Use FDA-grade HDPE tanks for safe storage.
• Regularly check for leaks or damage to tanks.
