CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 61/662,990, filed Jun. 22, 2012, which is incorporated by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    This invention relates to an aqueous dispersion of waxes, polymers, pigments and other functional additives, and its use as a concentrate of eye make-up compositions. 
       BACKGROUND OF THE INVENTION 
       [0003]    Mascara formulation is usually a viscous emulsion with ingredients such as waxes, emollients, pigments and film formers. In the production process, waxes, fatty acids and emollients are mixed and heat to 80-90° C. to melt and dissolve the waxes. Pigments and emulsifier then are added and dispersed in this oily mixture. Hydrophilic thickeners like gums or synthetic polymers are dispersed in hot water. Some of them require neutralization. This second phase is heated and combined with the oily phase to form the emulsion. 
         [0004]    Mascara and eyeliner formulations incorporate anionic soaps and non-ionic emulsifiers, such as glycerides and fatty alcohols. Their primary function is to emulsify waxes to sub-micron size and stabilize the Particles. 
         [0005]    However, emulsifiers can reduce the desired water-proofness because they cause films on lash to dissolve due to their hydrophilic nature. Some emulsifier can also be a source of skin and eye irritation. Many of the common emulsifiers for mascaras and eyeliners have regulatory issues and remain as questionable for the future, especially in Europe. Non ionic systems are preferred by many cosmetic companies. Less emulsifier provides better performance. 
         [0006]    The conventional manufacturing necessitate the heating and precise cooling, two sets of heating tanks and mixers. This not only incurs energy cost but also extends the production time because some processes cannot proceed until a certain temperature is reached. 
         [0007]    Moreover, processing, weighing, quality control and inspection of raw materials for a typical conventional process add the cost significantly. The quality assurance involves many aspects. In the current trend of cost-cutting, in order to remain competitive in the marketplace, it is desired to have a concentrate in the formulation process as a single component that contains all keep ingredients at an optimized ratio. 
         [0008]    Aqueous mascaras are wax-in-water emulsions that produce sub-micron Particles of waxes. Waxes are known to be melted and then emulsified to form wax-in-water emulsions which may then be used to produce both mascara and eyeliner products. Waxes are seldom added directly to an aqueous phase. EP394078 disclosed a cosmetic composition for hair treatment containing a microdispersion of wax in water using ionic or non-ionic emulsifier. U.S. Pat. No. 5,849,278 disclosed an eye makeup composition comprises an aqueous dispersion of wax Particles, at least one water-soluble film-forming polymer and pigments, the said dispersion being a microdispersion of colloidal wax Particles. The inventor claim that the addition of water-soluble film-forming polymers help the formula to exhibit remarkable qualities of regular and smooth deposits on the eyelashes. US20110250148 (A1) disclosed water dispersible wax powders for cold process emulsification. Water soluble polymers such as sodium polyacrylate are used to form a composite with waxes and help to dispersion the wax at room temperature. However, the water-soluble polymer can lead to a poor water resistance of the final eye make-up composition. 
       SUMMARY OF THE INVENTION 
       [0009]    It is an object of this invention to provide an aqueous dispersion of waxes, polymers, pigments and other functional additives, which can be used as a concentrate of an eye make-up composition. 
         [0010]    It was discovered, in a surprising manner, that when the all Particulate ingredients such as pigments, functional filler are incorporated to a solid loading of 70%, no additional emulsifier is needed to maintain the stability. Both the concentrate and dilutions of this technology to form mascaras &amp; eyeliners have improved water-resistance over conventional products. 
         [0011]    In one aspect, the present invention provides a dispersion composition comprising one or more waxes, one or more water-insoluble film-forming polymers, one or more pigments and other functional additives, wherein said dispersion has a viscosity in the range of about 150,000 cPs. to about 800,000 cPs. at about 25° C. and comprises at least about 60% of solids by weight. 
         [0012]    In one embodiment of this aspect, the dispersion composition is an aqueous dispersion, optionally containing an organic solvent. 
         [0013]    It is another object of this invention to provide a process for manufacturing the said dispersion using a cold process or a low heat process when the temperature is below the melting point of the wax. 
         [0014]    In another aspect, the present invention provides a method of making a dispersion composition as described herein, the method comprising: 
         [0015]    a) adjusting a polymer emulsion or dispersion with a base to a desired pH; 
         [0016]    b) adding one or more waxes to the polymer emulsion or dispersion under agitation; 
         [0017]    c) adding one or more functional additives to the mixture under agitation; and 
         [0018]    d) adding one or more preservatives under agitation. 
         [0019]    In another aspect, the present invention provides a method of making an eye composition, comprising: 
         [0020]    a) mixing one or more diluents with one or more preservatives to form a mixture; 
         [0021]    b) adding a dispersion composition according to any embodiments described herein and mixing till uniform; and 
         [0022]    c) filling with mixture obtained in b) with one or more filler materials. 
         [0023]    In preferred embodiments, no heating, cooling or homogenization is applied in the manufacturing processes. 
         [0024]    It is still another object of this invention to provide a method for making final eye makeup formulation from the above concentrated dispersion. Thus, in another aspect, the present invention provides rub-resistant and water-resistant mascara incorporating a dispersion composition according to any embodiment described herein. 
         [0025]    These and other aspects of the present invention will be better appreciated by reference to the following detailed description and claims.

         3. Add the Silica beads MSS-500/N in Part C and stir with the Cowles Mixer at low speed for 20 minutes. 
         4. Add the PMMA and stir with the Cowles Mixer at low speed for 20 minutes. 
         5. Add PART D Sericite to ABC. The viscosity will become thicker. Disperse with the Cowles Mixer at low speed for 20 minutes. 
         6. Slurry together the ingredients of PART E and add to Phase ABCD. Disperse very slowly with the Cowles Mixer at low speed for 20 minutes. Continue stirring until the air is reduced to a minimum. 
         7. Add the sorbic acid to the ethanol in PART E and stir together for 5 minutes. Add to the batch ABCDE. Disperse for 15 minutes. 
       
     
         [0127]    The solids of the concentrates were tested by drying at 105 C for 2 h and the value was in a range of 70-75%. Viscosity was tested using a Brookfield viscosity RVT at 2.5 rpm and the results were a range of 150,000-350,000 cps. They are stable at room temperature and 45 C in 2 months stability test. 
         [0128]    The concentrates can now be use to formulate a variety of the final mascara or eyeliner composition. The process is simple and easy. It requires only mixing at room temperature using a Cowles Mixer or the equivalent and a tank. No heating or homogenization is needed. The following are illustrative examples.

       Comparison Studies 
       [0166]    Leading marketed mascaras, 9 products from 8 brands, were purchased from Wal-Mart displays and used for the following tests: 
       Rub Resistant Test 
       [0167]    Rub resistance testing demonstrates the strength, adhesion and flexibility of the films incorporating the concentrate. Samples were weighed, applied to transpore tape to make films that were allowed to dry at 24 C for 24 hours. These films were abraded at a constant pressure and weight of 500 grams. The remaining film was digitized and transferred to image analysis software for results. A low score in the testing indicates by a low transfer during wear, also known as smudge-resistance (Table 1). 
       Water Resistance Test 
       [0168]    Water-resistance testing demonstrates the hydrophobic nature of the films incorporating the concentrate. A fixed amount of samples were weighed and applied in a Petri dish and allowed to dry at 24 C for 24 hours. The resultant films were then exposed to a circulating water bath for 4 hours. The remaining film was dried and weighed to determine its water-resistance. A high score in the testing indicating a high water-resistance during wear (Table 1). 
       Color Analysis 
       [0169]    For mascaras and eyeliners it is important that they have a deep, rich color or intensity. One gram of sample was applied and spread to a PMMA plate (3 inches in diameter) and allowed to dry for 24 hours. The color was analyzed by a Datacolor colorimeter using CIE Lab system. A lower L value indicates a darker color (Table 1).
