2) IODINE: It is slightly larger than chlorine atom & more germicidal & reactive. It is slightly soluble in water & readily soluble in alcohols & aqueous solution of sodium & potassium iodide. It is used in several forms like;
- Tincture of iodine: It consists of 2% iodine & sodium iodide dissolved in ethanol. It is used for the disinfection of water, & as antiseptics for wounds.
- Iodophors: It is iodine detergent complex that release iodine over a long period of time & hence added advantage of non-staining tissues or fabrics. The detergent complex portion of complex looses the organism from the surfaces & halogens kills them. Examples: Beta dine which is a povidone-iodine. Povidone is a surface active iodophor that improves the wetting action & serves as reservoir of free iodine. It is used for local wound cleaning. Wescodyne is used in pre-operative skin.
