Many operations depend to a great extent on effective mixing of fluids. Mixing refers to any operation used to change a non-uniform. Whereas emulsion is a special case of dispersion. Dispersion is a two-phase mixture in which drops may. Between the baffles and the wall is about 0.1–0.15 J. This ensures that the liquid does not form.

What is claimed is:1. A nail coating formulation which upon drying forms a film which will adhere to keratin of the nail and has a moisture vapor transmission from about 0.1 to about 1.6 mg./cm. 2 /hr., said formulation comprising an aqueous emulsion polymer having a solids content from about 30 to about 55 percent, the polymer having a T g within the range of about -10° C. To about 50° C. BACKGROUND OF THE INVENTIONMany types of cosmetic film forming compositions, including nail coating formulations, have been used in the past and are currently on the market.Most nail coatings now available are lacquers and consist of nitrocellulose, aryl sulfonamide formaldehyde resin, plasticizer and solvent mixture together with a small proportion of color and pigment. These nail lacquers have the disadvantages of discoloration of the nail (keratin), of having a flammable solvent present, of having a rather high occlusion of the nail, and of requiring a rather long drying time.The present nail coating formulation contains as the film-forming component an aqueous emulsion polymer which is prepared by polymerization of monomers in water. The emulsion has a solids content from about 30 to 55 percent and films made from the emulsion have a moisture vapor transmission from about 0.1 to 1.6 mg./cm.
The polymer has a T g from about -10° C. When measured by differential thermal analysis. The instant aqueous emulsion polymer nail coating formulation has the advantages of using water as the solvent so it is non-flammable, of having less occlusion of the nail to permit greater moisture vapor transmission of the nail, of eliminating the toluenesulfonamide formaldehyde resin, and of having a faster drying time than those lacquers of the prior art. The instant nail coating formulation has acceptable adherence to the keratin, gloss, viscosity, and durability.Some of the prior art concerning cosmetic film forming compositions is discussed below.The zinc-complex formulation disclosed in Chemical Week, 154 (June 21, 1969), is a zinc cross-linked formulation with a Carboset® (acrylic polymer). This formulation is an aqueous solution with the disadvantages of softening on contact with water, a rather low solids content, and poor resistance to alkali.U.S.

Although the disclosure purports to contemplate emulsion polymers, it is clear from the disclosure of polymerization conditions and suitable solvents for polymerization that aqueous emulsion polymers of the type employed in the present invention were not visualized. Also, this patent only exemplifies organic solvent systems for the nail lacquer formulations.SUMMARY OF THE INVENTIONThis invention relates to a nail coating formulation which upon drying forms a film which will adhere to keratin of the nail and has a moisture vapor transmission from about 0.1 to about 1.6 mg./cm. 2 /hr., said formulation comprising an aqueous emulsion polymer having a solids content from about 30 to about 55 percent, the polymer having a T g within the range of about -10° C. To about 50° C.
