A mascara applicator with vibrating applicator head. The head is caused to vibrate in a controlled manner through electro-mechanical urging. The frequency, amplitude and geometry of the vibrating head are sufficient to significantly alter the rheological properties of thixotropic and anti-thixotropic mascara compositions, including an effect that persists after the vibration has stopped. The device allows the mascara to be manipulated for improved results, greater flexibility in formulation, benefits in manufacture, as well as other benefits.

What is claimed is: 1. A vibrating mascara applicator comprising: a handle; a stem attached to the handle; a rod attached at its proximal end to the stem and extending beyond the handle; an eyelash applicator head attached to the distal end of the rod; and a means to vibrate the applicator head, such that the rod flexes in a direction perpendicular to its length when the applicator head is vibrating. 2. The applicator of claim 1 wherein the means to vibrate the eyelash applicator head comprises a DC motor subassembly having an axle, the center of mass of which is offset from its longitudinal axis. 3. The applicator of claim 2 wherein the motor subassembly is housed in the handle of the mascara applicator. 4. The applicator of claim 2 further comprising a DC power supply electrically connected to the motor. 5. The applicator of claim 4 wherein the DC power supply is one or more batteries. 6. The applicator of claim 5 wherein the one or more batteries are located in the handle of the applicator. 7. The applicator of claim 5 wherein the one or more batteries are standard carbon, zinc-carbon, alkaline, lithium, nickel-cadmium, nickel-metal hydride, lithium-ion, zinc-air, zinc-mercury oxide or silver-zinc batteries. 8. The applicator of claim 4 wherein the DC power supply is solar based. 9. The applicator of claim 8 further comprising one or more light collecting portions. 10. The applicator of claim 9 wherein at least some of the one or more light collecting portions are located on the handle of the applicator. 11. The applicator of claim 10 further comprising a cover, which, in a closed position prevents light from reaching the one or more light collecting portions and which, in an opened position allows light to reach the one or more light collecting portions. 12. The applicator of claim 9 further comprising one or more storage cells. 13. An applicator according to claim 2 further comprising one or more means for turning the motor on and off. 14. The applicator of claim 13 wherein at least one of the on/off means is a manual switch that can be engaged, either directly or indirectly, by a finger of the user. 15. The applicator of claim 14 wherein the switch is located on a side wall of the applicator or an end of the handle. 16. The applicator of claim 15 further comprising a cap that secures to the applicator to cover the switch. 17. The applicator of claim 14 wherein the switch is located on the handle and covered by a deformable membrane, such that pressure applied to a portion of the membrane activates the switch. 18. The applicator of claim 14 wherein the switch is a toggle switch, rocker switch, slider, button, rotating knob, touch activation surface, magnetic switch or light activated switch. 19. The applicator of claim 13 wherein the motor is capable of being automatically turned on when the applicator is drawn from a reservoir and capable of being automatically turned off when it is reinserted into the reservoir. 20. The mascara applicator of claim 2 wherein the motor subassembly can change speeds, either stepwise or continuously at the discretion of a user. 21. The mascara applicator of claim 1 wherein the amplitude of brush head vibration is about one sixty-fourth to about one quarter of an inch. 22. The mascara applicator of claim 21 wherein the amplitude of brush head vibration is about one thirty-second to about one eighth of an inch. 23. The mascara applicator of claim 22 wherein the amplitude of brush head vibration is about one sixteenth of an inch. 24. The mascara applicator of claim 1 wherein the frequency of brush head vibration is about 10 to about 1000 cycles per second. 25. The mascara applicator of claim 24 wherein the frequency of brush head vibration is about 10 to about 300 cycles per second. 26. The mascara applicator of claim 25 wherein the frequency of brush head vibration is about 30 to 100 cycles per second. 27. The mascara applicator of claim 1 wherein the means to vibrate the applicator head is reusable. 28. An applicator according to claim 1 that is capable of shearing a mascara such that after the shearing has stopped, a measurable effect on viscosity persists for at least two to five minutes.
