Hi, everybody. Our next question says which type of iodine preparation is known for its slow release of iodine, making it suitable for prolonged antimicrobial action. A iodine tincture B, iodophor see iodine crystals or D iodine powder. Well, our answer here will be Choice bio four. It does indeed have this characteristic of slow releasing. So it's good for prolonged action against microbes and it is used in health care settings. For this reason, it uses a skin disinfectant, surgical scrub and for medical instrument sterilization. We'll just touch briefly on our other answer. Choices. Iodine tincture choice A is a solution of iodine and alcohol. Well, this is an effective disinfectant as you can imagine, but it doesn't have this prolonged iodine release. So should I say not her answer and enjoy C iodine crystals and D iodine powder are both pure forms of solid iodine iodine crystals in crystalline form. Then obviously I powder in a powdered form. So we'll say pure solid iodine. But again, these don't have this prolonged release. Uh These can be used for chemical reactions or used as a starting material for solutions. But that's why C and D are not our correct answer. So again, the type of iodine preparation known for its slow release of iodine which makes it suitable for prolonged antimicrobial action is choice B iodophor. See you in the next video.
