An EPA-registered disinfectant must carry all of the following on its label EXCEPT which?

• A. The Word Concentrate
• B. The EPA Registration Number
• C. The Directions for Use
• D. The Active Ingredients

Answer: (A)

Disinfectant labels must provide information that ensures safe, effective use and accountability. The EPA Registration Number confirms the product is registered and tied to the exact label you’re using. Directions for Use detail how to apply the product correctly—dilution, contact time, surfaces it can be used on, required personal protective equipment, and any frequency or precautions. Active Ingredients disclose which chemicals are responsible for the disinfecting action, so users understand what’s in the product and can assess compatibility and safety.

The word “Concentrate” on the label is not required. A product may be labeled as a concentrate or as ready-to-use, but the essential elements—registration number, directions for use, and active ingredients—must still be present on every EPA-registered disinfectant label.
