  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 m 2 /s to 0.2 m 2 /s. The nitrogen-free non-functionalized polysiloxane material ranges in viscosity from 0.01 m 2 /sec to 2.0 m 2 /sec. The silicone blend is preferably used in a pre-formed emulsion which can be added to the balance of the detergent composition to form the droplets of the silicone blend which are dispersed in the detergent composition.

  本发明涉及水基液体洗衣粉组合物，用于清洁用其洗涤的织物并赋予织物护理功效。这种组合物包括：(A) 至少一种去污表面活性剂；(B) 由含氮氨基或铵官能化聚硅氧烷和不含氮的非官能化聚硅氧烷组成的有机硅混合物液滴；(C) 至少一种额外的非有机硅洗衣辅助剂，这些辅助剂选自去污酶、染料转移抑制剂、光学增白剂、泡沫抑制剂及其组合。有机硅混合物中的官能化聚硅氧烷组分具有相对较低的活性/固化基团含量，即小于 30 摩尔%，氮含量范围为 0.05% 至 0.30%（按重量计），粘度范围为 0.00002 m 2 /s 至 0.2 m 2 /s.无氮非官能化聚硅氧烷材料的粘度范围为 0.01 m 2 /秒至 2.0 米 2 /秒。硅氧烷混合物最好使用预制乳液，将其加入洗涤剂组合物的余量中，形成硅氧烷混合物液滴，分散在洗涤剂组合物中。
