ABSTRACT:
TECHNICAL FIELD
The present invention relates to cosmetic compositions, particularly eye make-up compositions, most particularly mascaras, comprising water-insoluble polymeric material in the form of an aqueous emulsion and water-soluble, film-forming polymers. In addition, the compositions herein utilize organophilic clays wherein the clays physically complex with the polymers. This serves to reinforce the film applied to the lashes such that smudging & smearing of the mascara is prevented.
BACKGROUND OF THE DISCLOSURE
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. Furthermore, the mascara should provide beauty benefits, particularly in terms of application benefits to the user.
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.
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 waterbased silicone elastomeric latex emulsions as opposed to “waterbased” acrylic polymers. Longer wear and durability is attributed to the use 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 that avoid combining plasticizers and insoluble-polymers are exemplified in EPO 0530084, published Mar. 3, 1993. This application discloses compositions comprising a internal phase and a external phase, wherein the external phase contains at least one water-soluble polymer and the internal phase contains at least 50% wax. Said composition may contain other materials routinely used in cosmetic compositions including water-insoluble polymers.
L'Oreals patent application, WO 91/12793, published May 4, 1994, discloses water-resistant composition for eyelashes containing at least one wax, at least one “consistency” agent, at least one volatile organic solvent and 1-35% (by weight of the composition) of an aqueous solution of at least one water-soluble, film-forming polymer. The level of water-soluble, film-forming polymers is between 0.1% and 55%, and does not contain any emulsifying agents. The processing instructions direct one to disperse the aqueous phase into the oil phase thereby making the composition a water-in-oil emulsion. Furthermore, the “consistency agent” (referred to in the specification as a “stability agent”) is selected from the group of organically treated argyles.
Organophilic clays are known for use with organic solvent and oil based systems. The benefits derived from the use of organophilic clays in these systems is three-fold. Organophilic clays provide viscosity, flow control and stability to these solvent-based and oil-based systems. This is similar to the way hydrophilic clay thickeners are used water-based products. For example, organoclay, reaction products of an organic quaternary amine with either hectorite or bentonite clay, are capable of swelling and gelling above mentioned organic-based systems to gel various hydrocarbon and natural oils, solvents and synthetic liquids; see “Controlling Cosmetic Rheology,” NL Industries (1985), p6.
Included among organic solvent-based and oil solvent-based systems are those which are anhydrous or contain water as the dispersed phase as in water-in-oil emulsion systems. Regardless of which of the organic or oil based system are employed, it is understood that the organophilic clays are dispersed in the lipophilic phase to thicken the viscosity of the oils and the vehicle overall. In this manner, they may also be combined with oil-soluble polymeric or resin materials.
Until now, however, nowhere has it been disclosed that non-organic solvent or oil based systems such as oil-in-water emulsions can benefit from the use of organophilic clays. By experimentation and ingenuity, it has been surprisingly found incorporating organophilic clays into oil-in-water cosmetic compositions as disclosed herein provides additional wear and beauty benefits not realized in the art.
SUMMARY OF THE INVENTION
The present invention is for mascara compositions, removable with soap and water, that provide surprising beauty and wear benefits as compared to compositions known in the art. These compositions comprise from about 3% to about 60% water-insoluble polymeric material, from about 2% to about 50% water-soluble, film-forming polymers, and from about 0.05% to about 20.0% organophilic clays.
Compositions of the present invention can be fabricated in a multitude of forms, such as creams, pastes and solids. All percentages are by weight of the cosmetic composition unless otherwise indicated. All solutions are on a weight/weight concentration unless otherwise indicated.
DETAILED DESCRIPTION OF THE INVENTION
A. Water-insoluble Polymeric Materials
The mascara composition of the present invention comprises water-insoluble polymeric materials in an aqueous emulsion. Said water-insoluble polymeric materials, disclosed in the art as latexes, are aqueous emulsions or dispersions of polymeric materials comprising polymers formed from monomers, said monomer derivatives, mixtures of said monomers, mixtures of said monomer derivatives, natural polymers and mixtures thereof. Said polymeric material also include chemically modified versions of the above polymers. These water-insoluble polymeric materials of the present invention comprise from about 3% to about 60%; preferably from about 4% to about 40% and most preferably from about 5% to about 30% by weight of the composition.
Water-insoluble polymeric material of the present invention comprise monomers selected from the group consisting of aromatic vinyls, dienes, vinyl cyanides, vinyl halides, vinylidene halides, vinyl esters, olefins and their isomers, vinyl pyrrolidone, unsaturated carboxylic acids, alkyl esters of unsaturated carboxylic acids, hydroxy derivatives of alkyl esters of unsaturated carboxylic acids, amides of unsaturated carboxylic acids, amine derivatives of unsaturated carboxylic acids, glycidyl derivatives of alkyl esters of unsaturated carboxylic acids, olefinic diamines and isomers, aromatic diamines, terephthaloyl halides, olefinic polyols and mixtures thereof. Preferred monomers are selected from the group consisting of aromatic vinyls, dienes, vinyl esters, olefins and their isomers, unsaturated carboxylic acids, alkyl esters of unsaturated carboxylic acids, hydroxy derivatives of alkyl esters of unsaturated carboxylic acids, amides of unsaturated carboxylic acids and mixtures thereof. Most preferred monomers are selected from the group consisting of aromatic vinyls, dienes, vinyl este
