Abstract

A two-step mascara product that includes a first mascara composition and a second mascara composition. The first mascara composition includes a film-forming polymer dispersed in a first carrier, and the second mascara composition includes a film-former selected from the group consisting of tall oil glycerides, pentaerythrityl rosinate, glyceryl rosinate, hydrogenated versions of these and mixtures thereof. The two-step mascara product also includes a package for storing and dispensing each of the first and second mascara compositions. The package includes a first container configured to store and dispense the first mascara composition and a second container configured to store and dispense the second composition.

First claim

What is claimed is:

1. A two-step mascara product comprising:
a. a first mascara composition, the first mascara composition including a film-forming polymer comprising an organosiloxane and a plurality of primary particles having an effective diameter of at least 5 microns dispersed in a first carrier, the first mascara composition having a viscosity in the range of 350,000 to 1,000,000 centipoise;
b. a second mascara composition second mascara composition comprising from 7% to 10% by weight of jet milled iron-oxide, said second mascara composition having a Critical Pigment Volume Concentration. the second mascara composition including from 10-80% by weight of a volatile second carrier consisting of isododecane and from 15-35% by weight of a film-former comprising a mixture of tall oil glyceride and at least one of pentaerythrityl rosinate or hydrogenate thereof, the second mascara composition having a viscosity in the range of 150,000 to 300,000 centipoise and a Delta L value of less than 2.5 according to the Rub Test; and wherein said film-former comprises equal amounts of said tall oil glyceride and said rosinate, wherein said glyceride and said rosinate are each present at concentrations in the range of 8.5% to 13.5% of weight of the composition;
c. distearyl dimonium hectorite clay particles as a thickener at a concentration of 10%-15% by weight of the second mascara composition; and
d, wherein the solids volume concentration of said second mascara composition, based on the volume concentration of said iron oxide particles and said clay particles, is less than the Critical Pigment Volume Concentration;
e. a double-ended package for storing and dispensing each of the first and second mascara compositions, the package comprising a molded plastic applicator joined to one end of a central ferrule and a twisted wire applicator joined to the opposing end of the central ferrule, the double-ended package further comprising a first container that is threadably engeagable with the central ferrule such that when it is engaged thereto the first container covers the molded plastic applicator, and a second container that is threadably engageable with the central ferrule such that when it is engaged thereto the second container covers the twisted wire applicator; wherein said molded plastic applicator is adapted to apply said first mascara composition as a base coat and said wire applicator is adapted to apply said second mascara composition as a top coat.
