Abstract

The invention provides liquid cleaning or bleaching compositions containing compounds having the structure of Formula I ##STR1## wherein A is a saturated ring formed by five atoms in addition to the N.sub.1 atom, the five saturated ring atoms being four carbon atoms and a heteroatom, the substituent R.sub.1 bound to the N.sub.1 atom of the Formula I structure including either (a) a C.sub.1-24 alkyl or alkoxylated alkyl where the alkoxy is C.sub.2-4, (b) a C.sub.4-24 cycloalkyl, (c) a C.sub.7-24 alkaryl, (d) a repeating or nonrepeating alkoxy or alkoxylated alcohol, where the alkoxy unit is C.sub.2-4, or (e) --CR.sub.2 R.sub.3 CN where R.sub.2 and R.sub.3 are each H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, the R.sub.2 and R.sub.3 substituents are each H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, and wherein Y is a generally anionic counterion and Z is in the range of 0 to 10. Additional, adjunct materials commonly found in liquid cleaning and bleaching compositions can be added.
