The invention is directed to liquid laundry detergent compositions comprising (a) at least one surfactant; (b) at least one enzyme and an enzyme stabilizing system comprising boron; (c) at least one fabric care ingredient which is not a fabric cleaning ingredient; and (d) at least one modified cationic polysaccharide-based deposition aid for the fabric care ingredient, wherein prior to modification, the cationic deposition aid contains at least one pair of cis-hydroxy groups, and wherein the cationic deposition aid is modified in such a way that the enzyme stabilizing system does not exhibit cis-hydroxy group interaction with the cationic deposition aid. The use of such compositions and methods for treating fabrics in fabric treatment applications including domestic laundering to thereby provide improved cleaning and fabric care are also covered.
