Mascara formulation

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.

         13 . A method of applying an oil-in-water anionic emulsion to eyelashes, the method comprising applying the emulsion to eyelashes such that the emulsion is in direct contact with hair shafts of the eyelashes, wherein 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; and   (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.   
     
     
         14 . The method of  claim 13 , wherein the oil-in-water anionic emulsion thickens the appearance of eyelashes when compared with eyelashes that do not include the oil-in-water anionic emulsion. 
     
     
         15 . The method of  claim 13 , wherein the oil-in-water anionic emulsion is applied to the eyelashes with a mascara wand. 
     
     
         16 . The method of  claim 13 , wherein the oil-in-water anionic emulsion comprises 14 to 17% by weight of paraffin wax, 2 to 5% by weight of carnuba wax, 2 to 5% by weight of beeswax, and 0.5 to 2% by weight of candelilla wax. 
     
     
         17 . The method of  claim 13 , wherein the oil-in-water anionic emulsion comprises 2 to 5% by weight of stearic acid, 2 to 5% by weight of palmitic acid, 0.1 to 1% by weight of myristic acid, 0.5 to 2% by weight of PEG-40 stearate, and 0.5 to 2% by weight of stearyl stearate. 
     
     
         18 . The method of  claim 13 , wherein the oil-in-water anionic emulsion further comprises VP/Eicosene copolymer, trimethylpentanediol/adipic acid/glycerin cross polymer, hydroxyethylcellulose, and bis-diglyceryl polyacyladipate-2. 
     
     
         19 . The method of  claim 18 , wherein the oil-in-water anionic emulsion comprises 0.1 to 1% by weight of VP/Eicosene copolymer, 0.5 to 2% by weight of trimethylpentanediol/adipic acid/glycerin cross polymer, 0.1 to 1% by weight of hydroxyethylcellulose, and 2 to 5% by weight of bis-diglyceryl polyacyladipate-2. 
     
     
         20 . The method of  claim 13 , wherein the oil-in-water anionic emulsion comprises iron oxide, triethanolamine, silica, benzyl alcohol, nylon-12, caprylyl glycol, and dimethicone. 
     
     
         21 . The method of  claim 13 , wherein the oil-in-water anionic emulsion comprises 5 to 15% by weight of iron oxide, 1 to 5% by weight of triethanolamine, 0.1 to 2% by weight of silica, 0.1 to 2% by weight of benzyl alcohol, 0.1 to 1% by weight of nylon-12, 0.1 to 1% by weight of caprylyl glycol, and 0.1 to 1% by weight of dimethicone. 
     
     
         22 . The method of  claim 13 , wherein the oil-in-water anionic emulsion further comprises chlorphenesin, panthenol, sorbitan stearate, synthetic fluorphlogopite, tocopheryl acetate, disodium EDTA, tocopheryl acetate, and cyclohexasiloxane. 
     
     
         23 . The method of  claim 13 , wherein the oil-in-water anionic emulsion further comprises a pigment. 
     
     
         24 . The method of  claim 13 , wherein the oil-in-water anionic emulsion is a mascara.
