Inhibitory Residue Test

Question:
How do I get an IRT?

Answer:
To get a lot number specific inhibitory residue test to comply with accreditation guidelines requiring lot specific or annual testing, get a certificate of analysis (COA) for the detergent you have. These COA’s can be found at http://www.alconox.com/section_dealers/certif_coa.asp

Lot numbers that you will need to get your COA are found at the top of 4 lb boxes (milk cartons), above the label on bottle, and on the side of the corrugated box for larger sizes and cases. These lot numbers are a "sub lot" of a specific master lot. Once the master lot number is identified on the COA, the inhibitory residue test data can be downloaded at www.alconox.com.

Master lot numbers change in the unusual event of a significant change in raw materials or manufacturing. Master lot numbers change such that each lot can be traced to a Master lot that was tested within one year.

Inhibitory residue tests are performed for each year's worth of sub lot numbers.
