## Abstract

The invention relates to relates to eye keratin material coating compositions including water, at least one low glass transition temperature (Tg) film-forming agent, at least one salt of an aromatic acid, and optionally at least one nonionic amphiphilic thickening agent, as well as to methods of using such compositions and kits containing such compositions.

## Claims

### Claim 1

An eye keratin material coating composition comprising water, at least one low glass transition temperature (Tg) film-forming agent, and at least one salt of an aromatic acid.

### Claim 2 (depends on 1)

The composition of claim 1, wherein at least one salt of an aromatic acid is selected from the group consisting of sodium benzoate, sodium salicylate, and mixtures thereof.

### Claim 3 (depends on 1)

The composition of claim 1, further comprising at least one nonionic amphiphilic thickening agent.

### Claim 4 (depends on 1)

The composition of claim 1, further comprising at least one water-soluble agent selected from the group consisting of polyols, C1-C5 monoalcohols, and mixtures thereof.

### Claim 5 (depends on 4)

The composition of claim 4, wherein the at least one water-soluble agent is present in an amount of about 10% or less by weight with respect to the weight of the total composition.

### Claim 6 (depends on 1)

The composition of claim 1, wherein the composition is substantially free of coloring agent.

### Claim 7 (depends on 1)

The composition of claim 1, wherein the composition is substantially free of hydrophilic thickening agent.

### Claim 8 (depends on 1)

The composition of claim 1, wherein the composition is substantially free of oil and wax.

### Claim 9 (depends on 1)

The composition of claim 1, wherein the composition is substantially free of surfactant.

### Claim 10

A method of applying artificial eye keratin material to natural eye keratin material comprising applying an eye keratin material coating composition comprising water, at least one low glass transition temperature (Tg) film-forming agent, at least one salt of an aromatic acid, and optionally at least one nonionic amphiphilic thickening agent, to natural eye keratin material, applying artificial eye keratin material to the natural eye keratin material upon which the composition has been applied, and allowing the composition to dry so that the artificial eye keratin material attaches to the natural eye keratin material.

### Claim 11 (depends on 10)

The method of claim 10, wherein the natural eye keratin material is an eyelid or a brow.

### Claim 12 (depends on 10)

The method of claim 10 wherein the natural eye keratin material is an eyelash or eyebrow.

### Claim 13 (depends on 10)

The method of claim 10, wherein the artificial eye keratin material comprises fibers attached to a substrate.
