  • Patent number: 6391840
    Abstract: The invention provides liquid bleaching compositions comprising multiple partial compositions held separately from each other in a multiple compartment container. One partial composition comprises a peroxygen bleach compound, preferably hydrogen peroxide. One partial composition (which may be the same as the one containing the peroxygen compound) comprises an imine or oxaziridine bleach activator compound. One partial composition, which is different from the one containing the bleach activator, comprises an alkaline compound in amount sufficient to raise the pH of the total composition to a value at which the bleach system is effective. The bleach activator compound is preferably a sulfonimine or a quaternary imine salt. The number of partial compositions and of the compartments in the container is preferably 2.

  • Patent number: 6042744
    Abstract: The invention provides a bleaching composition of pH 8-14 which comprises an oxygen transfer agent and hypochlorite or a source thereof and a method for bleaching a stained substrate which comprises the step of treating the substrate with a bleaching composition of pH 8-14 which bleaching composition comprises an oxygen transfer agent and hypochlorite or a source thereof. Particularly preferred oxygen transfer agents are imine quaternary ammonium salts such as N-methyl-3,4-dihydroisoquinolinium salts. Where these salts are used, suitable counter-ions include halides, sulphate, methosulphate, sulphonate, p-toluene sulphonate and phosphate. Oxygen transfer agents which comprise a quaternary nitrogen atom are preferred. In the alternative, the oxygen transfer agent can be a sulphonimine.
