1. A dispenser comprising: a first reservoir, the first reservoir comprising a first pump, the first pump comprising a first piston;a second reservoir, the second reservoir comprising a second pump, the second pump comprising a second piston;a first channel having a proximal end and a distal end;a second channel having a proximal end and a distal end;an exit orifice; andan actuator;wherein the proximal end of the first channel is in liquid communication with the first pump and the distal end of the first channel is in liquid communication with a first feed of a swirl chamber;wherein the proximal end of the second channel is in liquid communication with the second pump and the distal end of the second channel is in liquid communication with a second feed of the swirl chamber;wherein the swirl chamber comprises a first baffle and a second baffle and is in communication with the exit orifice;wherein said first piston and second piston are operatively associated with the actuator. 2. The dispenser of claim 1, wherein the first reservoir further comprises a first composition and the second reservoir further comprises a second composition; wherein the first composition comprises a carrier and a plurality of microcapsules and the second composition comprises a volatile solvent. 3. The dispenser of claim 2, wherein the first composition and the second composition mix prior to exiting via the exit orifice but do not mix prior to entering the swirl chamber. 4. The dispenser of claim 1, wherein first reservoir and the second reservoir have different volumes. 5. The dispenser of claim 1, wherein a dispensing volume is dispensed from the exit orifice, wherein said dispensing volume is from about 30 microliters to about 300 microliters. 6. The dispenser of claim 1, wherein the first pump and the second pump dispense different volumes. 7. The dispenser of claim 2, wherein the first piston and the second piston have different stroke lengths. 8. The dispenser of claim 2, wherein the first composition and second composition are dispensed as a mixture from the exit orifice at a volume ratio of from 3:1 to 1:3. 9. The dispenser of claim 2, wherein the swirl chamber further comprises a first inner swirl channel and a second inner swirl channel; wherein the first inner swirl channel is in communication with the first feed of the swirl chamber; and wherein the second inner swirl channel is in communication with the second feed of the swirl chamber. 10. The dispenser of claim 9, wherein the swirl chamber further comprises a first flow passage, a second flow passage, a third flow passage, and a fourth flow passage; wherein the first inner swirl channel is in communication with the first flow passage and second flow passage, and the second inner swirl channel is in communication with the third flow passage and the fourth flow passage; wherein the first flow passage, second flow passage, third flow passage, and fourth flow passage are also in communication with the exit orifice. 11. The dispenser of claim 10, wherein the swirl chamber further comprises a mixing zone; wherein said mixing zone is in communication with the exit orifice and the first flow passage, the second flow passage, the third flow passage, and the fourth flow passage. 12. The dispenser of claim 2, wherein the microcapsules comprise a core material and a shell encapsulating the core material; wherein the core material comprises a fragrance. 13. The dispenser of claim 12, wherein the shell comprises a material selected from the group consisting of polyacrylates, polyethylenes, polyamides, polystyrenes, polyisoprenes, polycarbonates, polyesters, polyureas, polyurethanes, polyolefins, polysaccharides, epoxy resins, vinyl polymers, and combinations thereof. 14. The dispenser according to claim 13, wherein the first composition is substantially free of a material selected from the group consisting of a propellant, ethanol, a detersive surfactant, and combinations thereof. 15. The dispenser according to claim 13, wherein the second composition is substantially free of a material selected from the group consisting of a propellant, microcapsules, a detersive surfactant, and combinations thereof. 16. The dispenser of claim 2, wherein the volatile solvent is ethanol. 17. The dispenser of claim 2, wherein the dispenser further comprises an assembly for flushing. 18. The dispenser of claim 1, wherein at least one of the first piston and second piston is operatively associated with an external compensator; wherein the external compensator is also operatively associated with the actuator. 19. The dispenser of claim 1, wherein one of the first piston and second piston is operatively associated with an internal compensator. 20. A method of increasing the longevity of a fragrance, the method comprising: dispensing a first composition comprising a plurality of microcapsules and a second composition comprising a volatile solvent from a dispenser, the dispenser comprising a first reservoir, the first reservoir comprising a first pump, the first pump comprising a first piston; a second reservoir, the second reservoir comprising a second pump, the second pump comprising a second piston; a first channel having a proximal end and a distal end; a second channel having a proximal end and a distal end; an exit orifice; and an actuator; wherein the proximal end of the first channel is in liquid communication with the first pump and the distal end of the first channel is in liquid communication with a first feed of a swirl chamber; wherein the proximal end of the second channel is in liquid communication with the second pump and the distal end of the second channel is in liquid communication with a second feed of the swirl chamber; wherein the swirl chamber comprises a first baffle and a second baffle and is in communication with the exit orifice; wherein said first piston and second piston are operatively associated with the actuator; wherein the first composition and the second composition do not mix before entering the swirl chamber.
