1. A device for dispensing a cosmetic composition, the device comprising a dispensing head comprising:
- a base fitted on a container containing the cosmetic composition;
an annular housing disposed on the base and comprising a supply duct configured to guide the cosmetic composition from the container to an inner surface of the housing;
an annular core disposed inside the housing such that an annular distribution chamber is formed between an outer surface of the core and the inner surface of the housing, the core having an inner surface that defines an opening of the dispensing head; and
axial ribs disposed between the core and the housing, the ribs at least partially defining dispensing orifices configured to divide the cosmetic composition received from the distribution chamber into separate streams and dispense the separate streams from the dispensing head, such that the streams are oriented parallel to one another and to a dispensing axis that extends axially through the annular core or converge upon the dispensing axis outside of the opening of the dispensing head,wherein the dispensing orifices each have a cross section of at least about 0.005 mm2 to about 0.01 mm2, such that the cosmetic composition is dispensed from the dispensing heat as an aerosol mist, andwherein 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 the propellant ranges from about 60% to about 90% by weight, with respect to the total weight of the pressurized composition.
