The quaternary ammonium compounds (QAC) are complex organic compounds possessing great surface activity and germicidal properties. At the present time there are hundreds of preparations on the market in the United States and about 100 licensed for sale in Canada which are compounded from or are composed entirely of one of the many QAC available. About 45 per cent of those available in Canada are composed in whole or in part of di-isobutylphenoxyethoxyethyl dimethyl benzyl ammonium chloride which, for brevity, will be referred to as Hyamine 1622, the trade name given this substance by the manufacturers, Rohm and Haas of Philadelphia, Pa.
