Sodium Percarbonate Storage — Oxygen Bleach Tank Selection

Storing Sodium Percarbonate? Start Here

Sodium percarbonate, often known as "solid oxygen bleach," is a popular choice for eco-friendly cleaning and stain removal. It releases hydrogen peroxide when dissolved in water, which helps bleach and disinfect. Used in products like OxiClean, it's a staple in both consumer and industrial cleaning. If you're looking to store sodium percarbonate, you need to consider how it interacts with water and other materials.

Can you store it in a poly tank?

Yes, you can store sodium percarbonate in poly tanks. High-density polyethylene (HDPE), cross-linked polyethylene (XLPE), and polypropylene (PP) are all suitable for both dry and dissolved forms. Just ensure the tank is well-sealed to prevent moisture contact, which can trigger hydrogen peroxide release.

Key Issue: Moisture Sensitivity

Sodium percarbonate is stable when dry, but exposure to moisture initiates its decomposition, releasing hydrogen peroxide. This can be beneficial in controlled applications but poses a risk if unintended. Ensure storage in a dry, moisture-barrier environment to maintain stability.

The safety that actually matters

• Keep the product dry to prevent premature decomposition.
• Use appropriate gaskets; EPDM or Viton are recommended for dissolved solutions.
• Store away from heat sources to avoid decomposition above 50°C.

Common questions

What happens if sodium percarbonate gets wet?

It releases hydrogen peroxide, which can lead to unwanted bleaching or cleaning reactions.

Can I use a standard steel tank for storage?

Dry storage is fine, but dissolved solutions can attack carbon steel. Stainless steel is preferable.

Is sodium percarbonate safe for colored fabrics?

Yes, it's often used for color-safe bleaching, unlike chlorine bleach.
