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.

Cette invention concerne des compositions détergentes à lessive liquides aqueuses servant à nettoyer et à entretenir les textiles lavés avec ces compositions . Ces compositions comprennent (A) au moins un tensioactif détergent; (B) quelques gouttes d'un mélange de silicone comprenant un polysiloxane fonctionnalisé ammonium ou amino contenant de l'azote et un polysiloxane fonctionnalisé dépourvu d'azote; et (C) au moins un additif de lessive non silicone supplémentaire sélectionné parmi des enzymes détergentes, des agents inhibiteurs de transfert de colorants, des azurants optiques, des suppresseurs d'eau savonneuse, ainsi que des combinaisons de ceux-ci. Le composant polysiloxane fonctionnalisé du mélange silicone présente une teneur relativement faible, autrement dit inférieure à 30 % en mol, en groupes réactifs/durcissables, une teneur en azote comprise entre 0,05 % et 0,50 % en poids et une viscosité comprise entre 0,00002 m?2¿/s et 0,2 m?2¿/s. Le matériau polysiloxane non fonctionnalisé dépourvu d'azote présente une viscosité comprise entre 0,01 m?2¿/s et 2,0 m?2¿/s. Ces compositions ne peuvent pas aussi contenir des polymères de formation de phase coacervée et/ou des agents cationiques facilitant le dépôt.
