  • Patent number: 7959685
    Abstract: The present invention provides a laundry detergent composition, a process for making said composition, the use of the composition in a laundry detergent and a method for treating fabric with the composition. Said laundry detergent compositions comprise a polyaspartate derivative modified with at least two hydrophilic groups, one of which is a charged hydrophilic group, surfactant and optionally other ingredients.
    Type: Grant

  • Publication number: 20110119841
    Abstract: The invention provides a method of laundering fabric which uses a pourable liquid detergent composition comprising 10-40% wt of surfactant, essentially consisting of nonionic and/or anionic surfactant (typically less than 90% wt LAS and at least 10% wt of nonionic surfactant) in which 10-40% wt of surfactant preferably passes the Calcium Tolerance Test described in the patent. The composition comprises no more than 15% wt of soap, (present as a minority in wt % terms of the total surfactant). In the method, the composition is diluted by a factor of greater than 500 to obtain a wash liquor which comprises 0.8-0.05 g/l of surfactant, and, the wash liquor is contacted with fabrics.

  • Publication number: 20090318324
    Abstract: The present invention relates to use of a compound for promoting antiredeposition during laundering of a textile fabric, in which the compound is a polymer comprising a polysaccharide backbone substituted by one or more groups -L-R1, where L represents an ester, amide or ether linkage and R represents an anionic alkyl group or a salt thereof, which has a degree of substitution of from 0.005 to 1 and a degree of biodegradation of at least 60% in 28 days. The use of such polymers in the manufacture of a laundry cleaning composition is also provided as well as laundry cleaning compositions containing such polymers.

  • Patent number: 6936577
    Abstract: A particulate laundry detergent composition which comprises a detergent base powder comprising surfactant and builder and, as separate particulate components: (a) an alkali metal carbonate salt selected from carbonate, bicarbonate, sesquicarbonate and combinations thereof; and (b) a water-soluble organic acid which, when reacted with (a) in the presence of water, generates carbon dioxide gas; wherein the alkali metal carbonate salt, when taken separately, has a 90% dissolution time of less than 15 seconds, preferably less than 10 seconds, more preferably less than 7 seconds; and the water-soluble organic acid has a d50 particle size which is in the range of from 150 to 1500 microns. The alkali metal carbonate salt preferably has an average bulk density of at most 1000 g/l, preferably at most 800 g/l, more preferably at most 600 g/l. The alkali metal carbonate salt preferably has a d50 particle size of at most 250 microns, preferably from 1 to 200 microns, more preferably from 10 to 150 microns.
