Using Chloroxylenol (PCMX) in Bar Soap

Chloroxylenol (PCMX) is a disinfectant ingredient commonly used in products like antiseptic soaps.

For use in bar soap as a disinfectant, a higher concentration than the limit for cosmetic preservatives is typically used. The FDA permits Chloroxylenol at a maximum rate of 0.5% when used as a preservative in cosmetic formulas (referring to the 100% powder form). However, for disinfectant products, higher rates are common. For example, Dettol uses Chloroxylenol at a rate of 4.80%.

Based on the information available, usage rates for disinfection can vary. For killing specific germs like Coronavirus, rates as low as 0.12% (100% powder) or 0.8% (15% water soluble) with a 30-second contact time are mentioned. For general hand disinfectant products, a recommended rate of 0.2% (100% powder) is noted.

Considering these points, a usage rate for disinfectant bar soap would likely be above the 0.5% preservative limit, potentially in a range similar to or lower than the 4.8% found in Dettol, depending on the desired level of disinfection and regulatory requirements for disinfectant products in your region. A common range for disinfectant soaps might be between 0.5% and 5%. Always check local regulations for disinfectant product formulations.

Precautions:

• Formulating with Chloroxylenol to ensure effective disinfection can be complex. If you are not experienced, it is recommended to use a ready-made disinfectant soap base rather than formulating from scratch to ensure efficacy.
• Chloroxylenol (100% Powder) is soluble in alcohol, organic solvents, and glycols. The 15% Water Soluble form is designed to dissolve in water. Consider the solubility when incorporating it into your soap base.
• It can withstand heat up to 80°C during processing.

Regarding compatibility with other substances, the available information does not list specific ingredients that should not be used with Chloroxylenol. However, as with any formulation, it's important to ensure overall compatibility and stability of the final product.
