Abstract (en)

[origin: WO0116269A1] A method for bleaching stained fabrics is provided by washing a stained fabric in an aqueous wash liquor in the presence of a wash additive that comprises a ligand that forms a transition metal complex as bleach catalyst, the complex catalysing bleaching of stains by atmospheric oxygen. The wash additive preferably comprises an iron complex comprising the ligand N,N-bis(pyridin-2-yl-methyl)-1,1-bis(pyridin-2-yl)-1-aminoethane. One or both of the wash additive and the wash liquor are substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system. The wash additive provides improved or broader stain profile bleaching.
