  • Patent number: 7335630
    Abstract: The invention is directed to aqueous liquid laundry detergent compositions for cleaning and imparting fabric care benefits to fabrics laundered therewith. Such compositions comprise (A) at least one detersive surfactant; (B) droplets of a silicone blend comprising a nitrogen-containing amino or ammonium functionalized polysiloxane and a nitrogen-free non-functionalized polysiloxane; and (C) at least one additional non-silicone laundry adjunct selected from detersive enzymes, dye transfer inhibiting agents, optical brighteners, suds suppressors and combinations thereof. The functionalized polysiloxane component of the silicone blend has a relatively low, i.e., less than 30 mol %, content of reactive/curable groups, a nitrogen content which ranges from 0.05% to 0.30% by weight and a viscosity which ranges from 0.00002 m2/s to 0.2 m2/s. The nitrogen-free non-functionalized polysiloxane material ranges in viscosity from 0.01 m2/sec to 2.0 m2/sec.
