<p>Novel cationic nitriles, methods of preparing such nitriles and use thereof as cationic peroxyacid bleach precursor in bleaching (detergent) compositons are disclosed. The novel cationic nitriles are non-hygroscopic and are characterized in that they have a counter-anion X<-> selected from the group consisting of 1) R-SO3<->, 2) R-SO4<->, 3) R-CO2<->, wherein R is a straight or branched chain, optionally substituted, alkyl, alkylether or alkylene group containing 4 to 20 carbon atoms, or a phenyl or alkyl phenyl group containing 6 to 20 carbon atoms, and 4) any other surfactant anion not falling under the groups 1), 2) and 3).</p> |
