Abstract

A semi-permanent mascara product that includes a supply of a semi-permanent mascara composition disposed in a container and a twisted-wire brush for applying the mascara to the eyelashes of a user. The combination of the semi-permanent mascara and twisted-wire brush provides improved eyelash separation and reduced clumping versus the same mascara composition and an unsuitable molded plastic brush.

Claims

1. A mascara product comprising:

a. a container for storing and dispensing liquid mascara;

b. a liquid mascara composition disposed in the container, the mascara composition including from 1-60% by weight of a colorant, from 10-80% by weight of a carrier, and from 15-50% of a film former selected from the group consisting of tall oil glycerides, pentaerythrityl rosinate, glyceryl rosinate, hydrogenated versions of these and mixtures thereof; and

c. an applicator for receiving the mascara composition and applying the mascara composition to a keratinous surface, the applicator including a core and a plurality of fiber bristles joined thereto and extending outwardly therefrom, a handle, and a stem disposed between the handle and the core, the handle being removably and reattachably joined to the container such that the core contacts the mascara composition when the handle is joined to the container.

2. The mascara product of claim 1, wherein the mascara composition is anhydrous and the colorant comprises a multitude of particles dispersed therein.

3. The mascara product of claim 2, wherein the colorant particles comprise jet milled black iron oxide having a particle size of less than 1 micron.

4. The mascara product of claim 1, further comprising less than 15% by weight of wax particles.

5. The mascara product of claim 1, further comprising a Weighted Average Thickness value at five strokes of less than 30 according to the Weighted Average Thickness test.

6. The mascara product of claim 5, wherein the Weighted Average Thickness value at the first stroke is greater than the Weighted Average Thickness value at the third stroke according to the Weighted Average Thickness test.

7. The mascara product of claim 5, wherein the Weighted Average Thickness value at the first stroke is greater than the Weighted Average Thickness values at the third and fifth strokes according to the Weighted Average Thickness test.

8. The mascara product of claim 1, wherein the mascara composition has a solids volume concentration that is less than the Critical Pigment Volume Concentration.

9. The mascara product of claim 1, wherein the carrier comprises a volatile solvent selected from the group consisting of volatile hydrocarbons, volatile silicones, and mixtures thereof.

10. The mascara product of claim 1, wherein the mascara composition has a Delta L value of less than 2.5 according to the Rub Test.

11. The mascara product of claim 1, wherein the mascara composition when applied to the eyelashes of a wearer remains intact on the eyelashes for more than 24 hours.

12. A mascara product comprising:

a. a container for storing and dispensing liquid mascara;

b. a liquid mascara composition disposed in the container, the mascara composition including from 1-60% by weight of a colorant comprising pigment particles, from 10-80% by weight of a volatile carrier, and from 15-35% of a film former selected from the group consisting of tall oil glycerides, pentaerythrityl rosinate, glyceryl rosinate, hydrogenated versions of these and mixtures thereof; and

c. a twisted-wire brush applicator that includes a twisted-wire core and between 400 and 800 fiber bristles securely joined thereto, the twisted-wire brush applicator including a handle and a stem joining the handle to the twisted-wire core, the handle being removably and reattachably joined to the container.

13. The mascara product of claim 12, further comprising a Weighted Average Thickness value at five strokes of less than 30 according to the Weighted Average Thickness test.

14. The mascara product of claim 13, wherein the Weighted Average Thickness value at the first stroke is greater than the Weighted Average Thickness value at the third stroke according to the Weighted Average Thickness test.

15. The mascara product of claim 13, wherein the Weighted Average Thickness value at the first stroke is greater than the Weighted Average Thickness values at the third and fifth strokes according to the Weighted Average Thickness test.

16. The mascara product of claim 12, wherein the mascara composition has a solids volume concentration that is less than the Critical Pigment Volume Concentration.

17. The mascara product of claim 12, wherein the volatile carrier is selected from the group consisting of volatile hydrocarbons, volatile silicones, and mixtures thereof.

18. The mascara product of claim 12, wherein the mascara composition has a Delta L value of less than 2.5 according to the Rub Test.

19. The mascara product of claim 12, further comprising from 1-25% of a thickener that includes disteardimonium hectorite clay particles.

20. A mascara product comprising:

a. a container for storing and dispensing mascara;

b. a liquid mascara composition disposed in the container, the mascara composition including

i. from about 1-60% by weight of a colorant comprising pigment particles, wherein at least some of the pigment particles are black iron oxide particles,
