ABSTRACT:
TECHNICAL FIELD
The invention is in the field of compositions for application to eyebrows and eyelashes to impart color, or for use in lining the eyes with color, or application to the skin as in a facial or body tattoo, or the lips as a semi-permanent lipcolor.
BACKGROUND OF THE INVENTION
Many women use a variety of products to beautify the eyes, including brow color, eye shadow, mascara, and eyeliner. Such products accentuate the eyes and in the case of lash products, will also give the appearance of longer lashes.
One of the common problems with eye products such as liners and mascara is that they often do not wear for long periods of time and have a tendency to smudge. With respect to eyeliner, more adventurous consumers have addressed this problem by having “permanent” eyeliner essentially tattooed onto the eyelids. This is a permanent cosmetic procedure and the eyeliner is not removable.
Cosmetic manufacturers are constantly exploring new formulas for such products that will fill the need gaps of longer wear and reduced smudging in a way that will not necessitate visits to beauty salons to have permanent cosmetics tattooed into the skin. The desired cosmetics should provide long lasting, durable wear, preferably one or more days, and be removable by the consumer whenever desired. In addition, the color should be rich and as natural looking as possible.
Typically, products for making up the eyes contain inorganic iron oxide pigments in an emulsion. Iron oxides are water insoluble and are generally ground with one or more oils in the composition to form what is referred to as a pigment grind. For example, traditional mascaras are mixtures of waxes, oils, and inorganic pigments. They may be anhydrous or in the emulsion form. Many of the so-called water resistant mascaras are anhydrous or contain minimal amounts of water, while traditional mascaras are often in the emulsion form. These types of mascaras are generally applied to the lashes and wear for periods of time ranging from several hours to one day. Users usually remove what remains of such products at the end of the day by washing with water. Another problem associated with such mascaras is their tendency to smudge when the user becomes warm or wears eye makeup that is oily. Moreover, since such products contain significant levels of wax and oil, the inorganic pigments that provide color may tend to be muted. This in turn provides a more artificial look to mascara coated lashes.
Similarly, eyeliner is usually a liquid product or in a pencil form. It is applied to the upper and lower lids to accentuate the eye area. While eyeliner is a very desirable beauty product, it tends to smudge very readily, especially when worn on lower lashes. The smudging is due, in part to the solubilizing of the dried eyeliner formula by skin oils, perspiration, and tears. Again, the iron oxides typically used to provide color to such products are muted and matte in tone, sometimes providing an artificial look to the liner especially when the color is very dark.
The major need gaps in the field of lash, brow, lip, and liner products relates to creating a color that has a rich, deep, natural tone, and at the same time providing a product that has the capability of extended wear (one or more days) if desired by the consumer, and where negative tendencies such as smudging upon exposure to perspiration, tears, and environmental assaults are reduced or eliminated. Because inorganic pigments are inexpensive and widely available, it is desirable to use inorganic pigments in such compositions.
The object of the invention is to prepare products for making up the eyes and skin, such as mascara compositions (or lash tints), brow color, eyeliner, lip color, facial or body tattoos that exhibit extended wear, look natural, provide a rich color, and exhibit reduced smudging.
Another object of the invention is to provide eye products that are capable of wearing for one to five days and provide a natural appearance.
Another object of the invention is to provide commercially acceptable, stable, products for making up the eyes.
SUMMARY OF THE INVENTION
The invention is directed to a single phase gel based makeup composition containing one or more iron oxide pigments, a film forming silicone acrylate copolymer solvated in volatile solvent, and one or more non-wax gelling agents capable of gelling the composition to a viscosity of at least about 1,000 centipoise at room temperature.
The invention is further directed to a single phase gel based makeup composition containing one or more iron oxide pigments, a film forming silicone acrylate copolymer solvated in volatile solvent, and one or more non-wax gelling agents capable of gelling the composition to a viscosity of at least about 1,000 centipoise at room temperature, wherein the composition is substantially free of waxes which are animal and vegetable derived lipids.

The invention is further directed to a single phase gel based makeup composition containing one or more iron oxide pigments, a film forming silicone acrylate copolymer solvated in volatile solvent, and one or more non-wax gelling agents capable of gelling the composition to a viscosity of at least about 1,000 centipoise at room temperature, wherein the composition is substantially free of (a) waxes which are animal and vegetable derived lipids and (b) nonionic emulsifiers.
The invention is also directed to a method for preparing an emulsion makeup composition comprising preparing a single phase gel composition containing one or more iron oxide pigments, a film forming silicone acrylate copolymer solvated in volated solvent, and one or more non-wax gelling agents wherein the single phase gel portion of the emulsion has a viscosity of at least about 1,000 centipoise at room temperature and combining said single phase gel composition with a polar phase to form an emulsion.
DETAILED DESCRIPTION
I. Single Phase Gel Composition
The claimed composition is gel based, which means that it is in a viscous gel-like form, e.g. semi-solid or viscous liquid. Preferably the composition has a viscosity ranging from about 1000 to 500,000, more preferably 5000 to 250,000, most preferably 7000 to 120,000 centipoise at room temperature (room temperature being bout 25° C.). The composition may be used as eyeliner, eyecolor, lashcolor, lipcolor, or a tattoo, or in any other fashion where extended wear is desirable. The compositions general exhibit wear that is longer than one day, and up to three days.
The composition exists in a single phase. The term “single phase” means that the composition exists in one homogeneous phase which contains the inorganic pigments, the film forming silicone acrylate copolymer solvated in volatile solvent, and the non-wax gelling agent. The term “solvated” means that the silicone acrylate copolymer may be dissolved or solubilized in the volatile solvent either in whole or in part, or dispersed in the volatile solvent. In both cases the silicone acrylate copolymer must be compatible with the volatile solvent. Similarly, the pigments may be solvated in the single phase composition, which means they are either solubilized or dispersed therein, and are compatible and stable therein. In either case, when the composition is applied to the desired surface, the volatile solvent evaporates at least in part and the film forming polymer sets on the surface trapping the pigment particles that were dispersed or solubilized in that phase on the surface. The ingredients found in this composition are further described herein.
Preferably the claimed compositions are substantially anhydrous. The term “substantially” means that the claimed compositions cont
