<p>Bleaching compositions comprising an inorganic peroxygen compound and a bicyclic or tricyclic diketone as an activator for the peroxygen compound. The composition preferably comprises about 1 to about 75 percent of the peroxygen bleaching compound and about 1 to about 75 percent of the bicyclic or tricyclic diketone bleaching compound activator. The conventional additives such as surfactants, antifoaming agents, fabric softeners, stabilizers, inorganic builder salts, buffers, enzymes and the like may be present as indicated. The compositions can be formulated as dry concentrated, aqueous solutions, aqueous solutions containing non-aqueous solvents, etc. The compositions are environmentally safe, effective as bleaching agents from below room temperature to higher temperatures, biodegradable and otherwise highly desirable.</p> |
