  • Publication number: 20020198128
    Abstract: Laundry or cleaning composition comprising: (a) an effective amount, preferably from about 0.0001% to about 99.9%, more typically from about 0.1% to about 25%, of a bleach activator and/or organic percarboxylic acid; (b) a catalytically effective amount, preferably from about 1 ppb to about 99.9%, of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycyclic ligand; and (c) at least about 0.1% of one or more laundry or cleaning adjunct materials, preferably comprising an oxygen bleaching agent. Preferred compositions are laundry compositions and automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits through the use of such catalysts in combination with bleach activators and/or organic percarboxylic acids.

  • Patent number: 6440921
    Abstract: The present invention relates to a bleaching composition comprising a pre-formed peroxycarboxylic acid and a surfactant system comprising at least two surfactants. These compositions are stable to deliver improved bleaching performance while also being safe to color and fabric. Furthermore, the compositions herein are also chemically and physically stable upon prolonged periods of storage time.

  • Patent number: 6440922
    Abstract: A detergent composition comprises a zeolite builder having a particle size, expressed as a d50 value, of less than 1.0 micrometers, an amylase enzyme, and an alkoxylated nonionic surfactant having a hydrophilic lipophilic balance value of less than 9.5 selected from the group consisting of alkoxylated adducts of fatty alcohols containing an average of less than 5 alkylene oxide groups per molecule. The detergent composition has been found to reduce white residue formation on fabrics washed with detergent containing small particle size zeolite.

  • Patent number: 6432900
    Abstract: The invention relates to ligands or complexes useful as catalysts for catalytically bleaching substrates with atmospheric oxygen, and as catalysts in the of treatment of textiles such as laundry fabrics whereby bleaching by atmospheric oxygen is catalysed after the treatment. The ligand is of the general formula: wherein R1, R2, and R3 independently represent a group selected from hydrogen, hydroxyl, halogen, —NH—C(NH)NH2, —R and —OR, wherein R=alkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl or a carbonyl derivative group, R being optionally substituted by one or more functional groups, and provided that two of R1, R2 and R3 are coordinating groups and one of R1, R2 and R3 is a non-coordinating group; Q independently represents a group selected from C2-3-alkylene optionally substituted by H, benzyl or C1-8-alkyl; and Q1, Q2 and Q3 independently represent specified linking groups.
