How can I calculate active parts per million (PPM) of the disinfectant I'm using?
To calculate active PPM, you’ll need three things – the active ingredient list from the disinfectant label, dilution rate of the product and a calculator. Below is an example of how this would be done using Neutral Germicidal Cleaner (#702):
- Step 1:
Add together active ingredient percentages from the label:
5.07% + 3.38% = 8.45% total active ingredients.
- Step 2:
Multiply by 10,000:
8.45 X 10,000 = 84,500
- Step 3:
Divide the result of Step 2 by the dilution rate (128 in the case of 702):
84,500 ÷ 128 = 660 PPM.
