Liquid formulation comprising an alcohol and highly water soluble manganese complex salt catalyst, bleaching formulation and cleaning agent comprising the same

A liquid composition containing a solvent selected from the group consisting of an ether of mono aliphatic alcohols having between two and six carbon atoms, mono-, di-, tri- or tetraalkylene glycols having between two, and four carbon atoms in the alkylene moiety, cyclohexanol, benzyl alcohol or glycerol, whereby one or more OH groups of said mono aliphatic alcohols, glycols, cyclohexanol, benzyl alcohol or glycerol are replaced by an OR group, whereby R is alkyl with 1 to 4 carbon atoms, and whereby the solvent contains 0-10 wt-% of an inorganic or organic acid, and dissolved therein a mononuclear or dinuclear Mn(III) or Mn(IV) complex salt having a non-coordinating counter ion selected from the group consisting of halides, nitrate, nitrite, thiocyanate, cyanate cyanide, sulfate, hydrogen sulfate, sulfate monoester, sulfonates, monocarboxylates, dicarboxylates and dicarboxylate monoesters, and having a water-solubility of at least 30 g/L at 20° C., and wherein the mononuclear or dinuclear Mn(III) or Mn(IV) complex comprises at least one ligand of formula (I)

• wherein:
• p is 3;
• R is independently selected from the group consisting of hydrogen, C1-C24 alkyl, CH2CH2OH and CH2COOH;
• or one R is linked to the nitrogen atom of another Q of another ring of formula (I) via a C2-C6 alkylene bridge, a C6-C10 arylene bridge or a bridge comprising between one and two C1-C3 alkylene units and one C6-C10 arylene unit, which bridge is substituted with zero or more C1-C24 alkyl groups;
• and R1, R2, R3, and R4 are independently selected from H, C1-C4alkyl and C1-C4-alkylhydroxy.
