Abstract (en)
[origin: WO0116268A1] A method for bleaching stained fabrics is provided by pretreating the stained fabric, before washing, with a pretreatment composition that comprises a ligand that forms a transition metal complex as bleach catalyst, the complex catalysing bleaching of stains by atmospheric oxygen. The pretreatment composition 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 pretreatment composition and the wash liquor are substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system. The pretreatment provides improved or broader stain profile bleaching.
