Once dry, a residue of the QAC compounds remains and provides germicidal activity until degradation occurs. Disinfecting: Kills almost all of the pathogens. Care must be taken when cleaning hypochlorite spills as organic materials such as cloth, sawdust and paper may spontaneously combust upon drying. While hypochlorites are very reactive, their useful properties are negatively impacted by factors such as suspended solids, high temperatures, light, water impurities and improper pH levels. Staff must check the surface temperature of items being sanitized with maximum registering thermometers or heat tape. [8] Carriers with iodophor solutions allow a sustained-release effect, resulting in continuous microbial mortality. Iodophors attach to the sulfurs of proteins such as cysteine, causing inactivation and cell wall damage. can degrade QACs. [2] While disinfection measures may be employed in food processing and preparation, it is much more common to utilize sanitization methods to reduce microbial presence. This helps prevent pathogens as well as pests. [14] In addition, the low amounts of QACs flowing into commercial sewage treatment facilities appear to combine with the anionic surfactants present to form complexes that reduce or eliminate toxicity.
