Definitions

  • This invention relates to detergent compositions containing low levels of amine oxides.
  • These amine oxides are substituted by at least one long chain alkyl or alkenyl group.
  • Preferred amine oxides have at least two alkyl, especially methyl, or two alkylene oxide, especially ethylene oxide, groups attached to the nitrogen atom(s).
  • These compositions produce an alkaline laundry liquor pH.
  • These compositions exhibit a breed range of remarkable textile treatment benefits, particularly enhanced soil release and cleaning properties.
  • U.S. Patent 3,985,923, Basadur, issued October 12, 1976, relates to the application of renewable soil release finish during the rinsing step from a dilute aqueous acidic solution.
  • the release agent is a copolymer based on a dibasic carboxylic acid and a glycolic compound.
  • U.S. Patent 3,962,152, Nicol, Hays, issued June 8, 1976 pertains to the laundry treatment deposition of renewable soil release finish to synthetic treatment fabrics treated therewith.
  • the soil release finish consists of ethylene terephthalate and polyethylene oxide terephthalate.
  • the performance benefits derived from the utilization of the like additives are premised on the deposition of a releasable coating onto the fiber from the laundry/rinsing step.
