The main disadvantages of iodophors are that they can be highly staining on many different types of surfaces, they work only within an acidic pH range and they tend to evaporate away at temperatures greater that 35 °C. Phenol is one of the first chemical disinfectants, and phenolic derivatives are still widely used. Asking for help, clarification, or responding to other answers. None are equally useful for all applications, and the presence of organic material may greatly reduce their effectiveness.

One of the most widely used iodophors is povidone-iodine, which is often used for the disinfection of surfaces in breweries and dairy industries. If iodophores come in contact with caustic agent residue (mostly because of inappropriate rinsing and being in the dead zones), unpleasant smell is created (so-called phenol smell). This thin film of povidone-iodine continues to have bactericidal action for up to 8 hours after application. Chlorhexidine gluconate scrub soap adequately prepares the skin, and no solution is required after the scrub. A comparison of concentrations in corresponding foods analyzed for the 2003–2004 NZTDS (Vannoort and Thomson, 2005) with early values produced by Hercus and Roberts (1927), indicates that the only foods that show higher concentrations are cheese and milk as a result of iodophor contamination, and eggs as a result of trace mineral supplementation of poultry feed (Table 129.1). This situation is also transitory by nature, and more likely to occur in individuals with goiter [314]. This in turn resulted in transient hypersecretion and increased levels of triiodothyroxine and thyroxine. Lautier performed extended studies on guinea pigs, and showed that the cutaneous irritation caused by povidone-iodine was within acceptable levels [315].

Other disadvantages of hypochlorites include corrosiveness to metals in high concentrations (>500 ppm), inactivation by organic matter, discoloring or “bleaching” of fabrics, release of toxic chlorine gas when mixed with ammonia or acid (e.g., household cleaning agents) 523-525, and relative stability 327. While iodine is toxic in large doses, it is also an essential nutrient in very small doses. It is difficult to predict its reaction and efficacy in a complex solution.
