## Abstract

The invention relates to a composition comprising at least one water-dispersible wax and at least one oil-dispersible micronized wax which, if desired, can be prepared at room temperature.

## Claims

### Claim 1

A composition comprising at least one water-dispersible wax comprising at least one acrylic acid moiety or a salt thereof, at least one oil-dispersible micronized wax that is a combination of micronized beeswax and a micronized soy wax, at least one oil and water, wherein the composition is in the form of a mascara.

### Claim 2 (depends on 1)

The composition of claim 1, wherein the composition is an emulsion.

### Claim 3 (depends on 1)

The composition of claim 1, further comprising at least one colorant.

### Claim 4 (depends on 1)

The composition of claim 1, further comprising at least one surfactant.

### Claim 5 (depends on 1)

The composition of claim 1, wherein the oil-dispersible micronized wax constitutes the main wax of the composition.

### Claim 6 (depends on 5)

The composition of claim 5, wherein the oil-dispersible micronized wax constitutes at least 70% by weight of the total amount of wax in the composition.

### Claim 7 (depends on 1)

The composition of claim 1, wherein the at least one micronized wax constitutes 5% to 65% by weight of the total weight of the composition.

### Claim 8 (depends on 1)

The composition of claim 1, wherein the at least one water-dispersible wax constitutes 0.5 to 20% by weight of the total weight of the composition.

### Claim 9 (depends on 1)

A method of making up eyelashes comprising applying the composition of claim 1 to eyelashes.

### Claim 10 (depends on 1)

A method of curling eyelashes comprising applying the composition of claim 1 to eyelashes.

### Claim 11 (depends on 1)

A method of making the mascara composition, claim 1 the method comprising adding the at least one micronized wax to at least one oil to form and oil phase comprising the micronized wax, adding the at least one water-dispersible wax comprising at least one acrylic acid moiety or salt thereof to water to form an aqueous phase comprising the water-dispersible wax, and mixing the two phases to form a composition.

### Claim 12 (depends on 11)

The method of claim 11, wherein the composition is an emulsion.

### Claim 13 (depends on 11)

The method of claim 11, wherein mixing occurs at room temperature.

### Claim 14 (depends on 1)

The composition of claim 1, wherein the at least one acrylic acid moiety or salt thereof is polyacrylate or a salt thereof.
