Abstract (en)
[origin: EP1445305A1] Use is claimed of nitrogen ligand-containing transition metal complexes as catalysts for peroxy compounds. Use is claimed of nitrogen ligand-containing transition metal complexes of formula (I) as catalysts for peroxy compounds. M(L)nXm (I) M : Mn, Fe, Co, Ni, Mo or W; L : a nitrogen-containing heterocyclic ligand; X = chloride, bromide, nitrate, perchlorate, sulfate, ammonia, tetrafluoroborate, hexafluorophosphate or an anion of a 1-22C organic acid; n : integer 2-4; and m : integer 0-4. Independent claims are also included for detergent, bleaching and cleansing agents containing (I).
