Abstract
Previous studies indicated that in general surface active materials improved the washing performance of alkaline detergents even though the same surface active agents were poor detergents. However, certain mixtures of alkaline and surface active materials showed poor washing performance even though they were found to have physical and chemical characteristics resembling those of excellent detergents. In view of the interest in surface active materials and detergent-sanitizers and the paucity of reliable information that would indicate what might be expected of them for dishwashing, a performance test study was made using a technique that has been described in earlier papers. A study was also made on the effect of the quaternary ammonium compounds on the washing performance of alkaline detergents by this procedure. (Author)
