Abstract
A quaternary ammonium compound is combined with a water-soluble anionic surfactant having a hydrophile/lipophile balance (HLB) of 14 or above to form a biocidal/surfactant composition in which the amount of (ii) is up to 50 wt % of the total weight of these components. In the presence of water or other suitable aqueous media, such compositions appear to form a soluble charge complex. But whatever actually happens in the aqueous medium, the surfactant properties of the quaternary ammonium compound are improved without jeopardizing or impairing its germicidal properties.
