How to get the lot and expiration date for Alconox, Inc. detergents

expiration date

Problem:  To assure that you are using effective detergent, you want to know that the detergent has not expired.  Alconox, Inc. detergents have a shelf life of two years from the date of manufacture.  You need to know the date of manufacture to determine the expiration date for Alconox, Inc. products.

Solution:    Most detergent packages are marked with a 24 months from the end of the month of manufacture shelf life.  The more robust and longer life ½ oz Alconox® Powdered Precision Cleaner and Tergazyme® Enzyme-Active Powdered Detergent powder sample packets, and Alcotabs® Tablet Pipet Detergent packages are marked with 36 months from the end of the month of manufacture.

Some liquid bottle packages of Alconox, Inc. detergents have expiration dates ink jet printed on the bottle next to the lot number just above the label.  For other packages, you can find the date of manufacture and expiration date on the certificate of analysis (COA) of the lot of detergent that you have.  For help finding the lot number of the detergent you have or help finding the COA, use alconox.com to click on ‘Support’ and select COA.

The below will help locate the lot number and expiration date locations:

  • 1 Qt (0.95L) and 1 Gal (3.8L) Bottle – above the label ink jet printed on
  • 4 lb (1.8kg) box  – upper right of To Open panel
  • Case boxes – upper right of Ship To panel
  • 5 gal (19L), 15 gal (57L) and 55 gal (208L) drums – vertical large lettering inkjet
  • 25 (11 kg) and 50 lb (22 kg) boxes – upper right of ship to panel
  • 100 lb (45 kg) lb and 300 lb (136 kg) drums – ink jetted on side of container not far from the label

You can also establish the expiration date using the lot number if you know it.  To estimate the expiration date from the lot number, use the 3rd and 4th character of the lot number.  The 3rd character is a letter that stands for the month of manufacture using A for January thru M for December skipping the letter I to avoid confusion with the number 1.  The 4th character of the lot number is a number which stands for the year of manufacture currently starting from the year 2010, such that 0=2010 and 9 = 2019.  Starting in the year 2020, 0 will mean 2020 and 9 will then mean 2029 and so on.  Knowing the month and year of manufacture, you now add two years and get the month of expiration.
