ABSTRACT:

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. Pat. No. 3,639,572, Henrich, issued Feb. 1, 1972; and mascaras as disclosed in U.S. Pat. No. 4,423,031, Murui et al., issued Dec. 27, 1983; and European Patent Application (EPA) 0568035, published Nov. 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 Aug. 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 Mar. 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.
SUMMARY OF THE INVENTION
According to one aspect of the present invention there is provided a cosmetic make-up composition suitable for use as a mascara or the like and which comprises:
(a) from about 0.1% to about 60% by weight of insoluble polymeric material in an aqueous emulsion;
(b) from about 0.1% to about 10% by weight of a first surfactant or mixture of surfactants having a weight averaged HLB of from about 3 to about 6; and
(c) from about 0.1% to about 10% by weight of a second surfactant or mixture of surfactants having a weight averaged HLB of from about 8 to about 15.
According to a second aspect of the present invention there is provided a cosmetic make-up composition suitable for use as a mascara or the like and which comprises:
(a) from about 0.1% to about 60% by weight of insoluble polymeric material in an aqueous emulsion; and
(b) from about 0.1% to about 10% by weight of an alkyl- or alkoxy-dimethicone copolyol having the general formula:

According to a third aspect of the present invention there is provided a cosmetic make-up composition suitable for use as a mascara or the like and which is in the form of an emulsion comprising:
(a) from about 0.1% to about 60% by weight of insoluble polymeric material in an aqueous emulsion; and
(b) from about 0.1% to about 80% by weight of lipophilic oil components including from about 0.1% to about 10% by weight of polyvinylpyrrolidone hexadecene copolymer.
The compositions of the invention exhibit improved wear, increased resistance to water and are easily removed with soap and water.
All percentages are by weight of composition unless otherwise indicated. All solutions are on a weight/weight concentration unless otherwise indicated.
DETAILED DESCRIPTION OF THE INVENTION
A first essential component of the make-up composition of the present invention is an insoluble polymeric material in an aqueous emulsion. Said materials, disclosed in the art as latexes, are aqueous emulsions or dispersions of polymeric materials comprising polymerized monomers, mixtures of monomers, derivatives of said monomers and mixtures of said monomers and mixtures thereof. These polymeric materials disclosed herein also include chemically modified (derivatives) of said polymeric material disclosed above. The polymerization process for making said polymeric material of the present invention is well known in the art. Such processes are disclosed in Kirk Othmer,
Encyclopedia of Chemical Technology, Volume
14, “Latex Technology” 3rd Ed. 1981; incorporated herein by reference. These insoluble polymeric materials of the present invention comprise from about 0.1% to about 60%; preferably from about 2% to about 40% and most preferably from about 3% to about 30% by weight of the composition.
