  • Method of pretreating and bleaching stained fabrics
    Patent number: 6451752
    Abstract: 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.

  • Method of bleaching stained fabrics
    Patent number: 6302921
    Abstract: 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.

  • Detergent bleaching composition comprising pentadentate ligand derivatives
    Patent number: 6165963
    Abstract: A detergent bleaching composition is provided comprising a compound inclug a specified pentadentate nitrogen-containing ligand. The compound can activate hydrogen peroxide or peroxyacids and provides favourable stain removal properties, particularly in the presence or iron, manganese or copper ions. In addition, an improved stability in alkaline aqueous environment has been obtained, in particular at the peroxy compound concentrations generally present in the fabric washing liquor.

  • Bleach and oxidation catalyst
    Patent number: 6140294
    Abstract: A bleach and oxidation catalyst is provided comprising a catalytically ace iron, manganese or copper complex including a specified pentadentate nitrogen-containing ligand. The metal complex can activate hydrogen peroxide or peroxyacids and provides favourable stain removal properties. In addition, a considerably improved stability of these metal complex compounds in alkaline aqueous environment has been obtained, in particular at the peroxy compound concentrations generally present in the fabric washing liquor.
