Dryer bar having void volumes

1. A dryer bar comprising a dryer bar composition, wherein the dryer bar composition comprises a void volume percentage from 0.33% to about 20% with respect to the total volume of the dryer bar composition, wherein said dryer bar composition comprises from about 41 wt % to about 61 wt % of fabric softening active and about 38 wt % to about 55 wt % of a carrier, wherein the softening active is a quaternary ammonium compound suitable for softening laundry.

2. The dryer bar of claim 1 , wherein the dryer bar composition comprises a void volume from about 1% to about 15%.

3. The dryer bar of claim 2 , wherein the dryer bar composition comprises a void volume from about 3% to about 10%.

4. The dryer bar of claim 3 , wherein the dryer bar composition comprise a void volume from about 3.19% to about 7.45%.

5. The dryer bar of claim 2 , further comprising a plastic carrier functionally attached to the dryer bar composition.

6. The dryer bar of claim 1 , wherein the dryer bar composition is essentially free of any detersive anionic surfactants.

7. The dryer bar according to claim 1 , wherein the dryer bar composition comprises a void volume from about 3% to about 10% with respect to the total volume of the dryer bar composition and wherein the dryer bar composition is made by a single screw extrusion process.

8. The dryer bar of claim 1 , wherein said carrier is wax.

9. A method of softening fabric comprising the step of installing a dryer bar inside an automatic laundry drying machine, wherein the dryer bar comprises a fabric softening composition, wherein the composition comprises a quaternary ammonium compound and wherein the composition comprises a void volume from about 3% to about 10% with respect to the total volume of the composition.

10. The method according to claim 9 , wherein said composition comprises from about 41 wt % to about 61 wt % of fabric softening active and about 38 wt % to about 55 wt % of a carrier.

11. The method according to claim 10 , wherein said carrier is wax.

12. The method according to claim 9 , wherein said dryer bar further comprises a plastic carrier functionally attached to the composition.
