Description: COSMETIC MAKE-UP COMPOSITIONS Technical Field The present invention relates to cosmetic make-up compositions, particularly eye make-ups and mascaras, comprising water-insoluble polymeric material in the form of an aqueous emulsion or latex. Said compositions have improved wear benefits compared to compositions known in the art and are easily removed with soap and water. Background of the Invention Eye make-up compositions, including mascara, are significant products in the cosmetics market. Mascara enhances the beauty of the wearer by coating the eye lashes, or in some instances eyebrows, with color. In spite of their beauty enhancing characteristics, conventional eye make-up preparations have been criticized for their failure to produce the desired effects during long periods of wear. Problems such as staining and smearing, commonly referred to as smudging, and flaking of the mascara from the eyelashes are well known. Even where longevity has been improved, such compositions also are known to be difficult to completely remove from the delicate eye area. An eye makeup composition conceptually having significantly superior wear life, yet, easy removability with soap and water would be very desirable. Eye makeup compositions comprising polymeric emulsions in order to eliminate smudging are well known in the art and typically include water- insoluble polymers, also referred to as latexes. Such compositions including eye shadows as disclosed in U.S. Patent 3,639,572, Henrich, issued February 1 , 1972; and mascaras as disclosed in U.S. Patent 4,423,031 , Murui et al., issued December 27, 1983; and European Patent Application (EPA) 0568035, published November 3, 1993. These compositions include plasticizers or solvents to assist in forming films using said latexes. These compositions are known to contain thickeners to adjust the viscosity of the composition. Said thickeners include water-soluble and water-swellable polymers, typically known for such use in the cosmetic art. In a different embodiment of the above concept is disclosed in Patent Cooperation Treaty application WO 94/17775, published August 18, 1994. The invention disclosed therein includes mascara compositions comprising water-based silicone elastomeric latex, emulsions as opposed to "water- based" acrylic polymers. Longer wear and durability is attributed to the used of the elastomeric latex as it is more compatible with the rest of the compositional matrix than the acrylic polymers. Other compositions known in the art which seek to avoid the combination of plasticizers and insoluble-polymer are exemplified in EPO 0530084, published March 3, 1993. This application discloses compositions comprising a dispersed phase and a dispersant phase , the dispersant phase containing at least one water-soluble polymer and the dispersed phase containing at least 50% wax. Said composition may contain other materials routinely used in cosmetic compositons including water-insoluble polymers. Surprisingly, it has been found that the combination of water-insoluble polymeric materials in an aqueous emulsion and particular surfactants provides mascara and other cosmetic make-up compositions that have superior wear and are removable with soap and water. These make-up compositions can be fabricated in a multitude of forms, such as creams, pastes and solids. Preferably the compositions of the present invention are water-in-oil and oil-in-water emulsions.

The mixing rate is increased to high and mixed until the pigments are uniformly dispersed throughout the lipid mixture; about 30-35 minutes. The emulsifiers are added to said lipid mixture while continuing to mix . In a second vessel equipped with mixing and heating, the water and the remainder of the water dispersible components are added. The aqueous mixture is mixed with heating until this aqueous mixture is about 85°C. Q.S. for any water loss from said aqueous mixture. The two mixtures are slowly combined and mixed with a high speed dispersator type mixer. The heat source is removed and the mixing is continued until the temperature of said combined mixture is from about 65°C- 70°C. Q.S. said combined mixture for any water loss. The preservatives and insoluble polymer component are added and mixed until homogeneous. Said combined mixture is cooled to about 45°C-47°C and any remaining components are added. Cooling and mixing is continued until said combined mixture is about 27°C to about 30°C. Said combined mixture is transfered to suitable storage containers for subsequent filling of retail size packaging. 2. Water-in-Oil Emulsions (Examples l-V) The components of phase A are premixed for 30 minutes at room temperature with high shear. The phase A premix is then heated to 85-90°C with high shear. The wax phase B ingredients are premixed and heated to 90°C with slow stirring for one hour. The wax phase is added to the phase A premix at 90°C and mixed for 20 minutes with high shear. Cooling is commenced and the water phase ingredients are added. Mixing is continued with high shear. The mixture is cooled to 45°C and the remaining ingredients are added. QS for paraffin loss.
