An Iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or povidone (forming povidone-iodine). The result is a water-soluble material that releases free iodine when in solution. Iodophors are prepared by mixing iodine with the solubilizing agent; heat can be used to speed up the reaction.

Commercial Use
Diluted iodophor is often used by brewers and winemakers to sanitize equipment and bottles. Its major advantage over other sanitizers is that when used in proper proportions it does not require rinsing. However, it can leave unattractive orange-brown stains on plastic parts and equipment that it is left in contact with.
It is often supplied in different concentrations and is further diluted with water before use. The label will advise the appropriate dilution ratio, commonly 1:1000 or 1:100. Equipment to be sanitized should be thoroughly clean and left in contact with the solution for at least 2 minutes.
Diluted iodophor is also used extensively in the dairy industry.
Application
Iodophors are most effective in an acidic medium (pH2 to pH 5)[1] but are effective up to pH7.
It is inactivated by proteins if the pH rises above pH4 and is inactivated if the temperature rises above 50 °C as the iodine is driven off as a gas.
The optimum concentration is >200 mg/L free iodine with a contact time of 2 minutes and 100 mg/L free iodine for cleaned and dried equipment. In a non-food-contact application the concentration may rise to 500 – 800 mg/L.[2]
Human Toxicity
"Based on a review of the available toxicology data, the [US EPA] has concluded that iodine and iodophor complexes are of very low toxicity by the oral, dermal, and inhalation routes of exposure."[3]

- Alphaproteobacterium strain Q-1 produces an extracellular multicopper oxidase (IOX), which catalyzes iodide (I(-)) oxidation to form molecular iodine (I2). In this study, the antimicrobial activity of the IOX/iodide system was determined. Both Gram-positive and Gram-negative bacteria tested were kil
