Aqueous compositions of copper salts and hydrogen peroxide

摘要

Aqueous compositions, methods of manufacturing such aqueous compositions, and methods of removing reducing and/or suppressing malodors using such aqueous compositions are described. These compositions utilize a combination of hydrogen peroxide, a source of copper II, nonionic surfactant and alcohol to provide a highly effective and stable malodor removing, reducing and/or suppressing composition. The compositions are particularly useful as aerosol compositions for effective malodor removal, reduction and/or suppression in particular malodors from open sites such as landfill and in closed domestic environments such as the home. Also described is a stabilized hydrogen peroxide solution, which is stable on the addition of copper (II) salts.
