- and combinations thereof;
- (b) X is a linking group selected from:
- an alkylene;
- —(CH2)p—;
- or —CH2—CH(OH)—CH2—;
- wherein:
- (i) p is on average from about 2 to about 6,
- (c) Q is —(O—CHR2—CH2)q—Z;
- wherein q is on average from about 0 to about 20;
- and further wherein:
- (i) R2 is a group selected from:

- B. an emulsifier comprising anionic surfactant;
- C. a detersive enzyme;
- D. a nitrogen-containing detersive surfactant selected from the group consisting of an amine oxide surfactant, an amine-functional detersive surfactant, an amide-functional detersive surfactant;
- and combinations thereof;
- E. other laundry adjunct materials;
- and
- F. a carrier comprising water;
- wherein the organosilicone is in the form of a microemulsion having an average particle size of less than about 0.1 μm, and the composition has a viscosity of from about 1 to about 5,000 mPa*s at 25° C. and a shear rate of 20 sec−1.
