Disinfectant Solution using Chloroxylenol (PCMX)

You are asking about making a disinfectant solution using Chloroxylenol (PCMX) (15% Water Soluble).

1. Using 2% of the 15% solution:

   • Mixing 2% of the Chloroxylenol (PCMX) (15% Water Soluble) product with water results in a solution containing 0.3% active Chloroxylenol (PCMX).
   • According to the product information, a concentration of at least 0.12% active Chloroxylenol is effective for disinfection (specifically mentioned for Coronavirus with a 30-second contact time).
   • Therefore, using 2% of the 15% solution (which gives 0.3% active PCMX) is an effective concentration for disinfection and can be used directly.
   • While this basic mixture is effective for killing germs, commercial disinfectant products often contain other ingredients like emulsifiers, fragrances, or stabilizers. However, for simple disinfection purposes, mixing the product with water at the appropriate concentration is sufficient.

2. Further Dilution:

   • Diluting the 2% solution (containing 0.3% active PCMX) further with a large amount of water (like 1 liter) will significantly reduce the concentration of active Chloroxylenol.
   • This reduced concentration will likely fall below the minimum effective level required for disinfection, especially against resilient pathogens like viruses.
   • For effective disinfection, it is not recommended to dilute the prepared 2% solution further. Use the 2% solution directly as your disinfectant.
