Abstract: Described herein are mono-quaternary ammonium salts of hydantoin having the formula: ##STR1## wherein: ONE OF R.sub.1 and R.sub.2 is hydrogen or lower alkyl of 1 to 6 carbons and the other is ##STR2## R.sub.3 and R.sub.4, which may be the same or different, are selected from the group consisting of hydrogen, alkyl of 1 to 6 carbons, phenyl or taken together R.sub.3 and R.sub.4 may be a cycloaliphatic group of 4 or 5 carbon atoms;R.sub.5, r.sub.6 and R.sub.7, which may be the same or different, are selected from the group consisting of benzyl or --C.sub.p H.sub.2p+1 ;X is a halide or sulfate anion; andP is an integer from 1 to 24.The salts are useful anti-static agents. A number of the salts possess broad spectrum fungicidal and/or bactericidal activity and, accordingly, compositions having such activity contain as an active ingredient certain mono-quaternary ammonium salts of hydantoin.

Abstract: Described herein are quaternary ammonium salts of hydantoin having the formula: ##STR1## wherein: WHEN R.sub.1 is -- C.sub.n H.sub.2n OH, R.sub.2 is ##STR2## and WHEN R.sub.1 is ##STR3## R.sub.2 is --C.sub.n H.sub.2n OH;R.sub.3 and R.sub.4, which may be the same or different, are selected from the group consisting of hydrogen, alkyl of 1 to 6 carbons, phenyl or taken together R.sub.3 and R.sub.4 may be a cycloaliphatic group of 4 or 5 carbon atoms;R.sub.5, r.sub.6 and R.sub.7, which may be the same or different, are selected from the group consisting of benzyl or --C.sub.p H.sub.2p+1 ;X is a physiologically acceptable anion;n is an integer from 1 to 4; andp is an integer from 1 to 24.The salts are useful anti-static agents, and certain possess broad spectrum fungicidal and/or bactericidal activity and, accordingly, compositions having such activity contain as an active ingredient certain quaternary ammonium salts of hydantoin.
