Abstract

A cartridge having a microfluidic die and a fluid composition in fluid communication with the microfluidic die is provided. The fluid composition includes from about 50% to about 100%, by weight of the fluid composition, of a perfume mixture, wherein the perfume mixture has a mol-weighted average C log P of less than or equal to about 2.9; a polyol; and from about 0.25 wt. % to about 9.5 wt. %, by weight of the fluid composition, of water.

Claims (30)

1. A cartridge comprising a microfluidic die and a fluid composition in fluid communication with the microfluidic die, the fluid composition comprising:

about 50 wt. % to about 100 wt. % of a perfume mixture, by weight of the overall composition, wherein the perfume mixture has a mol-weighted average C log P of less than or equal to about 2.9;

an oxygenated solvent selected from the group consisting of: a polyol, glycol ether, polyether, or combination thereof; and

about 0.25 wt. % to about 9.5 wt. % water, by weight of overall composition.

2. The cartridge of claim 1 , wherein the mol-weighted average boiling point of the perfume mixture is less than 250° C.

3. The cartridge of claim 1 , wherein the perfume mixture has a mol-weighted average C log P of less than or equal to about 2.5.

4. The cartridge of claim 1 comprising about 0.25 wt. % to about 7.0 wt. % water, by weight of the overall composition.

5. The cartridge of claim 1 , wherein the fluid composition is substantially free of suspended solids.

6. The cartridge of claim 1 , wherein the oxygenated solvent is a polyol.

7. The cartridge of claim 6 , wherein the oxygenated solvent is a glycol ether.

8. The cartridge of claim 1 , wherein the oxygenated solvent is present at a level of about 0.01 wt. % to about 20 wt. %, by weight of the overall composition.

9. The cartridge of claim 1 , wherein the microfluidic die comprises a heater.

10. A microfluidic delivery system comprising a housing and a cartridge that is connectable with the housing, wherein the cartridge comprises a reservoir for containing a fluid composition, a microfluidic die, and a fluid transport member configured to deliver the fluid composition from the reservoir to the microfluidic die, wherein the fluid composition comprises:

about 50 wt. % to about 100 wt. % of a perfume mixture, by weight of the overall composition, wherein the perfume mixture has a mol-weighted average C log P of less than or equal to about 2.9;

an oxygenated solvent selected from the group consisting of: a polyol, glycol ether, polyether, or combination thereof; and

about 0.25 wt. % to about 9.5 wt. % water, by weight of overall composition.

11. The microfluidic delivery system of claim 10 , wherein the mol-weighted average boiling point of the perfume mixture is less than 250° C.

12. The microfluidic delivery system of claim 10 , wherein the perfume mixture has a mol-weighted average C log P of less than or equal to about 2.5.

13. The microfluidic delivery system of claim 10 comprising about 0.25 wt. % to about 7.0 wt. % water, by weight of the overall composition.

14. The microfluidic delivery system of claim 10 , wherein the oxygenated solvent is a polyol.

15. The microfluidic delivery system of claim 10 , wherein the oxygenated solvent is present at a level of about 0.01 wt. % to about 20 wt. %, by weight of the overall composition.

16. A method of dispensing a fluid composition from a microfluidic die, the method comprising the steps of:

comprising a housing and a cartridge that is connectable with the housing, wherein the cartridge comprises a reservoir, a fluid transport member, a fluid composition, and a microfluidic die, the fluid composition comprising:

about 50% to about 100%, by weight of the fluid composition, of a perfume mixture, wherein the perfume mixture has an average C log P of less than about 2.9;

an oxygenated solvent selected from the group consisting of: a polyol, glycol ether, polyether, or combination thereof; and

about 0.25 wt. % to about 7 wt. %, by weight of the fluid composition, of water.

17. The method of claim 16 , wherein the mol-weighted average boiling point of the perfume mixture is less than 250° C.

18. The method of claim 16 , wherein the perfume mixture has a mol-weighted average C log P of less than or equal to about 2.5.

19. The method of claim 16 comprising about 0.25 wt. % to about 7.0 wt. % water, by weight of the overall composition.

20. The method of claim 16 , wherein the oxygenated solvent is present at a level of about 0.01 wt. % to about 20 wt. %, by weight of the overall composition.
