Bleaching compositions are provided that comprise a nitrile containing compound that
has the nitrile bonded to a quaternary nitrogen through a methylene unit (where one
or both of the normal hydrogens can be substituted), and two of the quaternary nitrogen
bonds are part of a saturated ring. This saturated ring contains from two to eight
atoms in addition to the quaternary nitrogen. A source of active oxygen will react
with the nitrile for bleaching applications. Particularly preferred nitrile containing
compounds are N-alkyl morpholinium acetonitrile salts.
