ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a kits, methods, and compositions for enhancing the appearance of the lips. The invention contemplates cosmetic compositions for applying the color to the lips, compositions for enhancing the finish the finish of the cosmetic, color enhancing powders, and formulations for removing the color. Kits containing the above compositions are also contemplated. The present invention also relates to methods of using the preceding compositions.
2. Description of the Prior Art
For many years, lipstick has been utilized as a cosmetic preparation for heightening or altering the color of the lips. Conventional lipstick is formed by a cosmetic coloring in a wax carrier. Although lipstick has many disadvantages, there has thus far been no suitable alternative.
The lipsticks which have heretofore been available have the marked disadvantage of being readily transferable from a person's lips to other objects. Lipstick smears and rubs off while swimming, smoking, kissing, or by any other contact of the lips with articles such as coffee cups, tea cups, napkins and clothing. This leads to the loss of the lipstick application when drinking beverages, when swimming, and even when in engaging in none of these activities due simply to licking the lips. Thus, while lipstick is normally initially applied in a relatively even application across the externally exposed areas of the lips, the application of lipstick will readily dissipate and assumes a nonuniform coverage. The greatest loss of the lipstick application is typically near the portions of the lips closest to a person's mouth. As a consequence, it is necessary to frequently reapply layers of lipstick in order to maintain a uniform coverage of a lipstick application on a person's lips. This frequent necessity for reapplication aggravates a further disadvantage of conventional lipstick.
Lipstick has the additional disadvantage of being susceptible to cracking and caking. This disadvantage is particularly pronounced when several layers of lipstick have been applied to attempt to replenish a lipstick application that has been lost due to transfer to other articles. As a consequence, the frequent reapplication of lipstick results in perceptible cracking and calling of the lipstick covering a person's lips. Caking and cracking of a lipstick application detracts from the natural appearance of the lips and is aesthetically undesirable.
Attempts have been made over the years to provide alternative cosmetic which do not entail the disadvantages of lipstick. For example, U.S. Pat. No. 2,230,063 describes a liquid lip rouge preparation which employs a combination of ethyl cellulose and wax-free shellac as film-forming materials. However, shellac does tend to crack. Heretofore, no suitable alternative to lipstick has been found.
SUMMARY OF THE INVENTION
The present invention is an innovative new alternative to lipstick. The cosmetic of the present invention does not take the form of a gooey stick, but rather is a unique, smear-proof and waterproof liquid that dries quickly to an extremely sheer, soft finish that feels remarkably like bare skin. In one embodiment, the cosmetic comprises between about 0.1 and about 20 parts of an alcohol soluble and water insoluble resin, between about 0.1 and about 15 parts of a cellulose, between about 0.1 and about 15 parts of a cosmetic pigment, and between about 50 and 99 parts of an organic solvent.
The cosmetic of the present invention is both smear-proof and waterproof. It will not streak, smear, or rub off while swimming, smoking, or kissing. Use of the cosmetic of the present invention avoids the disadvantages of stains on coffee cups, cheeks and collars. The cosmetic of the present invention has twice the staying power of lipsticks which purport to be waterproof or kiss-proof
The cosmetic of the present invention has further advantages in that it won't stick to dental work or braces. It can also be used on hair or eyebrows, as well as to cover any bald areas on the head. It can be used to cover scars or tattoos anywhere on the body.
The present invention provides a perfect cosmetic for busy professional women. It is highly advantageous for wear at weddings, parties, for use at the beach, for use while skiing and for wear during all active sports. The cosmetic of the invention is extremely attractive and can be worn at important dinner dates, as well as during informal events. The wearer can even sleep or shower while wearing the cosmetic, since it will not fade or smear under such circumstances. The user may apply several layers of the cosmetic to achieve the desired appearance.
The present invention also relates to compositions for enhancing the finish of the cosmetic. Such compositions, when applied over the cosmetic, transform the finish of the cosmetic from a matte to a high-gloss finish. The finish enhancing compositions also keep the lips soft and moist and may be massaged lightly into the lips prior to application of the cosmetic to condition and moisturize the lips. The finish enhancing compositions may be applied with an applicator wand. The user can apply the finish enhancing composition multiple times, whenever it is desired to moisturize the lips or to enhance the finish of the cosmetic.
The appearance of the lips can be further enhanced using color enhancing compositions comprising a colorant powder, which may be supplied in pressed or loose form. The colorant powder may be supplied in a compact and can be gently pressed onto the cosmetic using a brush. The colorant powders may also be used as a foundation base or may be applied between the second and third layers of the cosmetic. The visual effect of the colorant powders may be moderated by applying the finish enhancing composition over the colorant powder.
The present invention also relates to compositions for removing the cosmetic, finish enhancer, and color enhancers. These compositions may be dabbed on a tissue and applied to the lips when the user desires to remove the preceding compositions from the lips.
The present invention also relates to kits comprising the preceding compositions and to methods of using the preceding compositions.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In one broad aspect, the invention may be considered to be a cosmetic comprising between about 0.1 and about 20 parts of an alcohol soluble and water insoluble resin, between about 0.1 and about 15 parts ethyl cellulose, between about 0.1 and about 15 parts of a cosmetic pigment, and between about 50 and about 99 parts of an organic solvent. All parts used herein are percent by weight.
Preferentially, the solvent is denatured alcohol. In a preferred version the alcohol soluble and water insoluble resin is present in between about one and about 10 parts. In a further preferred embodiment, the ethylcellulose is present in between about 1 and about 10 parts. In a further preferred embodiment, the cosmetic pigment is present in between about 2 and about 10 parts.
In another broad aspect, the invention may be considered to be an improvement in a cosmetic employing a coloring agent and a plasticizer in a volatile solvent. The improvement is comprised of at least one film-forming agent present in an amount of at least about one percent wherein the film-forming agent is selected from the group consisting of: AMPHOMER (copolymers of N-tert-octylacrylamide, methyl methacrylate, hydroxypropylmethacrylate, acrylic acid and/or t-butyl aminoethylmethacrylate), AMPHOMER LOVOCRYL-47 (an octylacrylamide/acrylateibutylaminoethyl methacrylate copolymer), Carboset, JONCRYL (styrene/acrylate copolymers), QUADAMER (terpolymers of alkyl acrylamide, acrylamide or methacrylamide, N-vinyl pyrrolidone, and acrylic or methyacrylic acid), GANTREZ ( copolymers of vinyl methyl ether and monoalkyl esters of maleic anhychide), and polyvinyl acetate copolymers.
In yet another broad aspect, the invention may be considered to be an improvement in a cosmetic employing a pigment and a film-form
