Povidone-iodine | 25655-41-8 FAQs

Povidone iodine has a complex structure where iodine is bound to povidone (polyvinylpyrrolidone), forming a water-soluble polymer-iodine complex that slowly releases iodine for sustained antimicrobial action.

The chemical formula of povidone iodine is (C6H9NO)n·xI, representing a polymer base with iodine. It’s not a simple molecule but a stable complex used widely in antiseptic formulations.

Povidone iodine is highly soluble in water and also dissolves in alcohols. This excellent solubility allows it to be used in liquid antiseptic products like scrubs, rinses, and topical solutions.

The polymer structure of povidone iodine enables slow iodine release, ensuring prolonged antimicrobial activity. This controlled release minimizes tissue irritation while maintaining effective disinfection over time.

Povidone iodine is preferred due to its water solubility, stable structure, and reduced irritation. Its chemical complex allows effective iodine delivery without the harshness of pure iodine applications.
