    Abstract

    Using a metal-modified polyhedral oligosilsesquioxane (I), (II), (III) or (IV) as an activator for inorganic peroxygen compounds in oxidizing-, washing-, cleaning- or disinfecting solutions, is claimed. Using a metal-modified polyhedral oligosilsesquioxane of formula (I), (II), (III) or (IV) as an activator for inorganic peroxygen compounds in oxidizing-, washing-, cleaning- or disinfecting solutions, is claimed. M : metal, preferably Mn, Fe, Mo, Au, Cu or Ce; L : anionic or neutral ligand; n : 0 or 1-5; A, B1 : -H, -ML n or SiR1R2R3; R1, R2, R3 : -OH, -COOH, -OR or R; and R : optionally mono- or polysubstituted carboxy-, phosphono-, sulfo-, sulfato- or hydroxy-substituted 1-44C alkyl, 1-44C aryl, 1-44C alkaryl or 1-44C aralkyl, where the alkyl chain is interrupted by at least one non-adjacent O. Independent claims are also included for: (1) using a system made of peroxocarboxylic acid-forming substance under perhydroloysis conditions and (I), (II), (III) or (IV) for enhancing the cleaning performance of detergents and cleaning agents in an aqueous surfactant containing liquor; (2) using a combination of peroxygen compound and (I), (II), (III) or (IV) for bleaching colored stains during washing of textiles, preferably in aqueous surfactant-containing liquor, or in cleaning solutions for hard surfaces, preferably for tableware, for bleaching colored stains, preferably of tea; and (3) a washing-, cleaning- or disinfecting agent comprising (I), (II), (III) or (IV).
