Quat Ammonium DDAC Sanitizer Storage — Food-Contact Quat Tank Selection

Storing Quat Ammonium DDAC Sanitizer? Start Here

Quat ammonium DDAC sanitizer is a powerful no-rinse solution used widely in foodservice, dairy, and food-processing industries. It’s excellent for sanitizing food-contact surfaces like utensils, prep counters, and equipment exteriors. Typically supplied as a concentrate, it’s diluted to a 200-400 ppm solution for effective use. If you’re looking to store this sanitizer, knowing the right tank materials and handling practices is crucial for safe and efficient operations.

Can you store it in a poly tank?

Yes, you can store DDAC sanitizer in polyethylene tanks. High-density polyethylene (HDPE) and cross-linked polyethylene (XLPE) are both suitable for storing this sanitizer, meeting FDA compliance standards. These materials are chemically compatible with DDAC at both concentrate and diluted strengths.

Key Issue: Material Compatibility

While polyethylene tanks are suitable, be cautious with other materials. Avoid using carbon steel or galvanized metals, as they can deactivate the sanitizer. Also, steer clear of cotton or cellulose mop heads during application, as they bind with the sanitizer and reduce its effectiveness. Instead, opt for synthetic fibers or microfiber materials.

The safety that actually matters

• Use FDA-compliant materials for all storage and application equipment.
• Ensure proper dilution to 200-400 ppm for safe food-contact use.
• Avoid using anionic materials that can neutralize the sanitizer.
