What is the function of povidone-iodine?
POVIDONE IODINE is an antiseptic and disinfectant used to treat and prevent skin infections in minor burns, lacerations (deep cut in the skin), cuts, and abrasions (the first layer of skin is scraped off).
What is the difference between iodine and povidone iodine?
Iodine is a pure chemical element, and povidone-iodine is a product containing iodine as the main substance. The key difference between them is, Iodine is naturally available in sea water and in the earth crust whereas povidone iodine is a man- made product that contains iodine.
What is the pH of povidone iodine?
This product is highly soluble in water, has a red- dish-brown color, and has a pH of approximately 4.5 [1,3]. Povidone-iodine scrub contains 7.5 percent polyvinylpyrrolidone-iodine, 0.75 percent available iodine, and an anionic detergent added for scrub- bing and lather-forming purposes [5].
Is povidone iodine bactericidal or bacteriostatic?
Povidone-iodine (PVP-I) is a broad-spectrum microbicide that can inactivate not only bacteria but also viruses (3). However, PVP-I may not function well in the presence of organic materials, such as blood or pus, which can rapidly neutralize its bactericidal activity (4).
How is povidone iodine made?
Povidone-iodine is manufactured as a solution by itself (povidone-iodine solution) or in conjunction with an ionic detergent (povidone-iodine scrub preparation). The detergent in the scrub preparation seems to be toxic to several normal tissues and to components of an open wound.
