What factors does TDLR classify sodium chlorite solutions into?

Sodium chlorite solutions are classified by the Texas Department of Licensing and Regulation (TDLR) based on concentration and exposure time. This classification is important because the effectiveness of sodium chlorite as a disinfectant or antimicrobial agent relies on both how concentrated the solution is and for how long it is applied to a surface.

Higher concentrations are typically more effective in killing bacteria, viruses, and fungi, but the necessary exposure time can vary depending on the specific pathogens present and the type of surface being treated. For example, some disinfectants may require longer contact times to ensure that microorganisms are effectively eliminated. Understanding both factors allows professionals in the field to appropriately use sodium chlorite solutions to ensure safety and efficacy in their work.
