  • Patent number: 4077898
    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.

  • Patent number: 3960781
    Abstract: Diaryl urethanes made by capping poly (oxyalkylene) diols with monoisocyanates are characterized by a desirable hydrophobe/hydrophile balance typically evidenced by low cloud points, the ability to form micelles in aqueous media, the ability to reduce stable foam, and the ability to be taken up and retained by paper fibers, the low foaming or de-foaming capability of these compounds is useful in machine dishwashing detergents and additives, which hydrophobe/hydrophile balance is typically obtained through a combination of oxyethylene and oxypropylene units or blocks in the oxyalkylene chain.
