Abstract:
1. A microbicidal buffered hydroalcoholic povidone iodine composition comprising: a buffered stock solution formed from 87% by weight purified water, 0.4% by weight granular citric acid, 0.5% by weight granular sodium phosphate dibasic, 0.1% by weight sodium hydroxide, 0.9% by weight glycerin, 0.9% by weight nonoxynol-9, and 10% by weight granular povidone iodine; and a reacting solution formed from 94% by weight alcohol, 5% by weight anesthetic, and no more than 0.13% by weight benzalkonium chloride, wherein the buffered stock solution and the reacting solution are combined in a stable solution having between 15-50% by weight alcohol content by mixing equal parts by weight the stock solution with the reacting solution to produce an exothermic reaction, and wherein a protective polymerized film configured for the sustained release of medicament forms when the stable solution is applied to the site of an injury.
