Problems solved by technology

But "long-lasting" is a relative term, and existing long-wear mascaras are designed to eliminate repeated applications throughout the day and are generally not suitable for multi-day application
One problem with long-wearing mascaras is making the composition sticky enough to remain on the lashes, yet sticky enough to cause excessive clumps of the lashes
Some clumps are unavoidable, but if too many individual lashes stick together and appear as large clumps, the consumer cannot achieve the desired look

Embodiment 1

[0141] The mascara composition according to the present invention having the composition of Table 1 was prepared according to the method directly given in Table 1 below.

[0142] Table 1

[0143] mascara composition

[0144] Mutually

[0145] Melt Phase A ingredients and mix together with low shear mixing. Phase B was gradually added to phase A and then dispersed with high shear mixing. Phase C was then added and mixed in with high shear mixing. Phase D is then added and dispersed with high shear mixing. The batch was cooled to ambient conditions, then phase E was added and mixed in.

Embodiment 2

[0147] Other mascara compositions No. 1-4 as described in the present invention were prepared and had the compositions given in Table 2A below.

Embodiment 3

[0162] Another mascara composition having a composition according to Table 3 was prepared according to the following method.

[0163] table 3

[0164] The mascara composition of the present invention

[0165]

[0166] Phase A was heated to allow the pigment to disperse using a Cowles blade mixer. The phase B materials were stirred together at ambient conditions, and the phase C materials were also stirred together at ambient conditions, which were then added to phase B (into the gel phase B), the mixture was stirred and then heated to about 85°C . Mix phase A and phase B / C together to create an oil-in-water (wax) emulsion. The mixture was stirred for 15 minutes, then gradually cooled to room temperature. During cooling, phases D and E were added to the mixture and stirred below 60 °C. After the mascara has cooled to about 25°C-50°C, phase F is added and mixed with the mascara.

Abstract

A method of coating eyelashes and / or eyelids with a cosmetic composition that includes from about 15% to about 50%, by weight, of a film former selected from the group consisting of tall oil glyceride, pentaerythrityl rosinate, glyceryl rosinate, and the hydrogenated versions and mixtures thereof. Further there is from about 0.1% to about 14%, by weight, of a colorant. In one embodiment of this invention the mascara composition comprises less than about 3.0%, preferably less than about 1.0%, even more preferably less than 0.1%, by weight, of wax and wax like components. In another embodiment, the mascara is substantially free of wax. The cosmetic composition is long lasting and has excellent wear characteristics.

Description

field of invention [0001] The present invention relates to long-wear mascara compositions and methods of coating eyelashes, eyebrows and / or eyelids with said compositions. The mascara compositions may be formulated for use as eyeliner or brow products. The mascara can remain on the eyelashes and / or eyelids for more than 24 hours, and in certain embodiments, for more than 48 hours. The methods of the present invention may comprise applying mascara to the eyelashes as a single application or as a first layer with a topcoat. Solvent based removal compositions are also disclosed because the mascara compositions of the present invention have very low solubility in soap and water. Background of the invention [0002] Mascara compositions have been used for many years to increase the thickness, length and overall appearance of human eyelashes. There are generally two categories of mascaras: regular and waterproof. Regular mascaras are generally water-soluble, while waterproof t...
