    Patent number: 6576602
    Abstract: Disclosed are nonaqueous, particulate-containing liquid laundry detergent compositions which are in the form of a suspension of particulate material, preferably including peroxygen bleaching agent and an organic detergent builder, dispersed in a liquid phase structured with alkylbenzene sulfonate anionic surfactant-containing powder. Such compositions provide especially desirable cleaning and bleaching of fabrics laundered therewith and also exhibit especially desirable pourability and chemical and phase stability.
    Type: Grant
    Filed: June 24, 1997

  • Non-aqueous, particulate-containing liquid detergent compositions with elasticized, surfactant-structured liquid phase
    Patent number: 5814592
    Abstract: Disclosed are non-aqueous, particulate-containing liquid laundry detergent compositions which are in the form of a suspension of particulate material, preferably including peroxygen bleaching agent and an organic detergent builder, dispersed in a liquid phase structured with a surfactant and elasticized with finely divided particulate material such as silica or titanium dioxide. Such compositions provide especially desirable cleaning and bleaching of fabrics laundered therewith and also exhibit especially desirable pourability and chemical and phase stability.
