Multi-Component Detergent Comprising Catechol Metal Complex

A multi-component detergent, comprising at least two components, that is contained in a container having at least two chambers, wherein

• a first component K1 is a first liquid composition, containing
• at least one catechol metal complex compound of formula (I)
• where
• R1 and R2 represent, independently of one another, a hydrocarbon functional group having 1 to 20 carbon atoms that is optionally substituted by at least one functional group selected from hydroxy, (C1-C4)-alkoxy, (C1-C4)-alkoxy(CH2CH2O)n—, —NR′R″ or —N+R′R″R′″X−, where n=1 to 10, R′, R″ and R″′ represent, independently of one another, H or a linear or branched aliphatic hydrocarbon functional group having 1 to 3 carbon atoms and X− represents an anion,
• Z1 and Z2 represent, independently of one another, OH or O−,
• M represents a metal cation of a transition metal or lanthanide,
• q represents, as a charge number of the metal cation M, the number 2, 3 or 4,
• p represents, as a charge number of the catechol ligand, the number 0, 1 or 2,
• r represents the number 1, 2, 3 or 4, and
• at least one free catechol compound of formula (II) or the salt thereof
• where
• R3 and R4 represent, independently of one another, a hydrocarbon functional group having 1 to 20 carbon atoms that is optionally substituted by at least one functional group selected from hydroxy, (C1-C4)-alkoxy, (C1-C4)-alkoxy(CH2CH2O)n—, —NR′R″ or
• —N+R′R″R″′X−, where n=1 to 10, R′, R″ and R″′ represent, independently of one another, H or a linear or branched aliphatic hydrocarbon functional group having 1 to 3 carbon atoms and X− represents an anion,
• with the proviso that the catechol compound of formula (II) and the salt thereof are different from the compounds of formula (I),
• and a second component K2 is a second liquid composition, containing at least one surfactant.
