Abstract

The subject of the invention is a device for dispensing a cosmetic composition, said device comprising a dispensing head (1) intended to be fitted on a container containing said cosmetic composition to be dispensed,

• • (i) the dispensing head comprising:
  • a body (3) that is open at its two opposite axial ends,
  • an engaging part (10) that is open at its two opposite axial ends and at least partially defines a dispensing orifice (12), and
  • (ii) the cosmetic composition comprising, in a cosmetically acceptable medium,
  • at least one cosmetic active agent, in particular at least one deodorant active agent and/or antiperspirant active agent,
  • at least one C₁ to C₅ alcohol,
  • at least one propellant,
    the concentration of propellant being between 60% and 90% by weight with respect to the total weight of the pressurized composition.

Claims

1-10. -10. (canceled)

11. A device for dispensing a cosmetic composition, said device comprising:

a dispensing head fitted on a container containing said cosmetic composition to be dispensed;

wherein the dispensing head comprises;

a body that is open at two opposite axial ends;

an engaging part that is open at two opposite axial ends and at least partially defines a dispensing orifice; and

wherein the cosmetic composition comprises, in a cosmetically acceptable medium;

at least one cosmetic active agent;

at least one C₁ to C₅ alcohol; and

at least one propellant;

wherein the concentration of propellant ranges from about 60% to about 90% by weight, with respect to the total weight of the pressurized composition.

12. The device of claim 11, wherein the dispensing orifice is annular and has a constant width in the circumferential direction.

13. The device of claim 11, wherein the dispensing orifice exhibits axial symmetry.

14. The device of claim 11, wherein the engaging part at least partially defines a plurality of dispensing orifices.

15. The device of claim 14, wherein the number of dispensing orifices is greater than or equal to 10.

16. The device of claim 14, wherein the dispensing orifices each have a cross section greater than or equal to about 0.003 mm².

17. The device of claim 11, wherein the at least one C₁ to C₅ alcohol is present in an amount ranging from about 38% to about 55% by weight, with respect to the total weight of the non-pressurized composition.

18. The device of claim 11, wherein the cosmetic composition is substantially free of solid particles and fillers.

19. The device of claim 11, wherein the cosmetic composition is substantially free of polymer.

20. A process for the dispensing of a cosmetic composition comprising:

dispensing a cosmetic composition from a dispensing device, said device comprising;

a dispensing head fitted on a container comprising a cosmetic composition to be dispensed;

wherein the dispensing head comprises;

a body that is open at two opposite axial ends;
