Abstract

Disclosed is an oil-in-water anionic emulsion for eyelashes, and methods for its use, comprising a continuous phase comprising 35 to 55% by weight of water based on the total weight of the emulsion, a discontinuous phase comprising 15 to 25% by weight of a combination of waxes, wherein the combination of waxes comprises paraffin wax, carnauba wax, beeswax, and candelilla wax based on the total weight of the emulsion, and 5 to 15% by weight of the emulsion of an anionic surfactant system comprising stearic acid, palmitic acid, myristic acid, polyethylene glycol-40 (PEG-40) stearate, and stearyl stearate, wherein the oil-in-water anionic emulsion is capable of thickening the appearance of eyelashes.

The invention claimed is:

1. A method of thickening the appearance of eyelashes and increasing the volume of eyelashes, the method consisting of directly applying an oil-in-water anionic emulsion to eyelashes, wherein:
direct application of the oil-in-water anionic emulsion to the eyelashes thickens the appearance of the eyelashes and increases the volume of the eyelashes; and
the oil-in-water anionic emulsion comprises:
(a) a continuous phase comprising 35 to 55% by weight of water based on the total weight of the emulsion;
(b) a discontinuous phase comprising 15 to 25% by weight of a combination of waxes, wherein the combination of waxes comprises paraffin wax, carnauba wax, beeswax, and candelilla wax based on the total weight of the emulsion;
(c) 5 to 15% by weight of the emulsion of an anionic surfactant system comprising stearic acid, palmitic acid, myristic acid, polyethylene glycol-40 (PEG-40) stearate, and stearyl stearate; and

5. The method of claim 1 , wherein the oil-in-water anionic emulsion comprises 2 to 5 wt. % stearic acid, 2 to 5 wt. % palmitic acid, 0.1 to 1 wt. % myristic acid, 0.5 to 2 wt. % PEG-40 stearate, and 0.5 to 2 wt. % stearyl stearate.

6. The method of claim 1 , wherein the oil-in-water anionic emulsion comprises 0.1 to 1 wt. % VP/Eicosene copolymer, 0.5 to 2 wt. % trimethylpentanediol/adipic acid/glycerin cross polymer, 0.1 to 1 wt. % hydroxyethylcellulose, and 2 to 5 wt. % bis-diglyceryl polyacyladipate-2.

7. The method of claim 1 , wherein the oil-in-water anionic emulsion further comprises iron oxide, triethanolamine, silica, benzyl alcohol, nylon-12, caprylyl glycol, and dimethicone.

8. A method of thickening the appearance of eyelashes and increasing the volume of eyelashes, the method consisting of directly applying an oil-in-water anionic emulsion to eyelashes, wherein direct application of the oil-in-water anionic emulsion to the eyelashes thickens the appearance of the eyelashes and increases the volume of the eyelashes, and wherein the oil-in-water anionic emulsion comprises:
