What are iodophores primarily composed of when combined with iodine?

Iodophores are primarily composed of a complex of iodine with a carrier or surfactant, commonly a nonionic detergent. This combination allows for the slow release of free iodine, which acts as an antimicrobial agent. The inclusion of a detergent enhances the solubility and distribution of iodine, making it more effective for disinfection purposes.

In contrast, other options such as phenolic compounds or alcohols do not represent the fundamental composition of iodophores. Phenolic compounds can serve as disinfectants but do not form the basis of iodophore formulations. Similarly, while alcohols are used in various antiseptic solutions, they lack the iodine complex characteristic of iodophores. Thus, the primary feature of iodophores being combined with a detergent is what makes them unique and effective for their intended purpose.
