Granules are provided that are useful for oxidizing applications when the granules are dissolved in the presence of an active oxygen source. These granules include a salt having the structure of Formula I ##STR1## wherein A is a saturated ring formed by a plurality of atoms in addition to the N.sub.1 atom, the saturated ring atoms including at least one carbon atom and at least one of O, S, and N atoms, 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 C.tbd.N 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 being 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, Z is in the range of 0 to 10, and wherein Y is a counterion. The salt is carried by, coated with, or admixed with a solid particulate such as silica gel, silicic acid, silicate, aluminum oxide, clay, aluminum silicate, or mixtures thereof.

A dry bleaching composition, particularly useful for low temperature applications, is provided in which generation of hypochlorite by reaction between a peroxygen bleaching agent and a chloride salt is promoted by an aromatic diol or oxidized aromatic diol activator. Preferred activators are in ester form and provide hypochlorite generation at levels of less than about 20 ppm for at least about the first two minutes following dissolution of the compositions in aqueous solution, but rising to effective bleaching levels within a reasonable time thereafter. The initially low hypochlorite level assists in the functioning of laundry additives, such as fabric brighteners.
