Abstract

Claims (21)

1. A mascara system comprising, in combination:

(a) a mascara applicator comprising a substantially longitudinal stem having a major axis A and a plurality of protrusions extending therefrom, wherein at least two adjacent protrusions are spaced from one another at a distance R at the base of the stem;

(b) a mascara composition comprising primary particles that are at least about 5 microns in equivalent diameter and at least one secondary particle that is structured to pack between the primary particles in the cosmetic composition; and

(c) a dermatologically acceptable carrier;

wherein the mascara applicator is a molded applicator, wherein the distance R is from about 0.75 mm to about 3.0 mm, wherein at least one of the primary particles is a wax primary particle composed primarily of one or more waxes.

2. The mascara system of claim 1 , wherein at least some of the primary particles are selected from the group consisting of solid particles, hollow particles, porous particles, and mixtures thereof.

3. The mascara system of claim 1 , wherein at least some of the primary particles are structured to absorb a liquid.

4. The mascara system of claim 1 , wherein at least some of the primary particles are structured to swell to at least about 5 microns in equivalent diameter.

5. The mascara system of claim 1 , wherein the wax primary particle comprises at least one wax having a melting point of from about 40° C. to about 150° C.

6. The mascara system of claim 1 , wherein the wax primary particle comprises at least one wax having a melting point of from about 100° C. to about 150° C.

7. The mascara system of claim 1 , wherein the mascara composition is selected from the group consisting of anhydrous, water-based, oil-in-water emulsions, water-in-oil emulsions, water-in-silicone emulsions, silicone-in-water emulsions, multiple emulsions and mixtures thereof.

8. The mascara system of claim 1 , wherein the mascara composition has a yield point of from about 0 Pa to about 1000 Pa and a viscosity of from about 2000 centipoise to about 6000 centipoise.

9. The mascara system of claim 1 , wherein the mascara composition enables a mascara film of about 5 microns to about 100 microns in equivalent diameter to deposit onto an eyelash.

10. The mascara system of claim 1 , wherein the wax primary particles comprise at least one other material embedded inside the wax primary particles.

11. The mascara system of claim 10 , wherein the other material is selected from the group consisting of pigments, preservatives, fillers, active ingredients, polymers, organic and inorganic solids, and mixtures thereof.

12. A mascara system comprising, in combination:

(a) a mascara applicator comprising a substantially longitudinal stem having a major axis A and a plurality of protrusions extending therefrom, wherein at least two adjacent protrusions are spaced from one another at a distance R at the base of the stem;

(b) a mascara composition comprising primary particles that are at least about 5 microns in equivalent diameter and at least one secondary particle that is structured to pack between the primary particles in the mascara composition; and

(c) a dermatologically acceptable carrier;

wherein the distance R is from about 0.75 mm to about 3.0 mm, wherein the primary particles are hollow particles.

13. The mascara system of claim 12 , wherein the mascara composition enables a mascara film of about 5 microns to about 100 microns in equivalent diameter to deposit onto an eyelash.
