Iodine water sterilization

Starch is extensively used due to its adsorbing properties. In dissolved form, it is used as a skin emollient and as an antidote for iodine poisoning. Other applications include the use as a tablet filler and binder and disintegrant. Sterilized starch is used as a lubricant for surgeon gloves. Unlike talc, it is completely adsorbed by body tissues. Soluble starch is prepared by treating commercial potato starch with dilute hydrochloric acid until it forms an almost clear solution in hot water.

The major natural food source of iodine is fish. The iodine content of fish reflects that of the water they inhabit thus, high levels of iodine are present in marine fish and shellfish compared to freshwater fish (Figure 45.1). Milk and dairy products contain relatively high amounts of iodine and are considered to be the most important sources of iodine in developed countries. The iodine content of milk is largely influenced by the use of iodophors as teat sterilants and equipment sanitizers in dairy husbandry, and the supplementation of animal feeds due to iodine deficiency in dairy cattle, exacerbated by the inclusion of goitrogenic feeds in the diet (COT, 2003). In addition, seasonal variations in the iodine content of foods are particularly evident in cows milk, with greater iodine... 

Low-volume eye lotions with antiseptics (iodinated povidone, polihexanide or chlorhexidine salts) for use in eye surgery must not contain preservatives. They are usually prepared aseptically in pharmacies using water for injection and sterile excipients, analogously to Table 10.18. Iodinated povidone eye lotion is thermally unstable and membrane filtration (<0.2 pm) has to be applied.
