Abstract
Ethanolamine (preferably triethanolamine) salts of phosphate esters (i.e., phosphate esters of ethoxylated alcohols) are used as carrier or complexing agents for iodine (e.g., in preparing pre-surgical germicidal compositions). These solutions have "fast-draining" properties and are especially useful for sanitizing containers in automated or continuous-line operations.
