  • Patent number: 7001878
    Abstract: The present invention relates to a liquid unit dose comprising a water-soluble packet and a liquid encased within the packet, the liquid being a detergent composition comprising: from 5% to 80% by weight of surfactant; from 1% to 15% by weight of non-aqueous solvent; less than 10% by weight of water; wherein the liquid detergent composition comprises fatty acid and further comprises fatty acid soap, wherein the molar ratio of fatty acid to fatty acid soap is from 5:1 to 1:5, and wherein the total level of fatty acid (neutralized and unneutralized) is from 20% to 50% by weight of the liquid composition.
    Type: Grant
    Filed: September 22, 2004
    Date of Patent: February 21, 2006
    Assignee: The Procter & Gamble Company
    Inventors: Francesco De Buzzaccarini, Lorenzo Matteo Pierre Gualco
  • Patent number: 6949496
    Abstract: The present invention relates to detergent compositions, especially liquid, granular and tablet forms of laundry detergent compositions, that comprise improved hydrotropes, wherein the hydrotropes are organic molecules in which two polar groups are separated from each other by at least 5 aliphatic carbon atoms; liquid compositions that contain such hydrotropes have a viscosity, dilution profile and dissolution behavior that render the product effective and convenient for use as a liquid laundry detergent composition.
    Type: Grant

  • Patent number: 6815410
    Abstract: The present invention relates to a pouched cleaning composition wherein the pouch is constructed from a water-soluble film and contains a liquid composition comprising less than 5% by weight of the liquid composition, of water; an anionic surfactant; and at least 0.5% by weight of the liquid composition of a builder/chelant free of C8-22 alkyl or alkenyl chains characterized by a solubility in said liquid composition of less than 0.3% by weight. Such pouched cleaning compositions provide better cleaning performance and better pouch solubility while avoiding the formation of residues.
