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 0.50% 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. Such compositions may not additionally contain coacervate phase-forming polymers and/or cationic deposition aids.
