More particularly, the present invention relates to fast-drying compositions which enhance long wear through their fast-drying properties. When applied to mammalian nails, the present fast-drying compositions exhibit a 5% Diluent Content Time of less than about 38 minutes and or exhibit a 5% Diluent Content Time of less than about 44 minutes and has an Initial Slope greater than about 2.25.
What is claimed is: 1. A fast-drying composition suitable for use as a nail polish for mammalian nails comprising:(a) a film-forming, water-borne polymer; and (b) a liquid diluent comprising:(i) at least about 20%, by weight of the composition, of a volatile organic solvent; and (ii) at least about 4% water;wherein the composition exhibits a 5% Diluent Content Time of less than about 38 minutes. 2. A composition according to claim 1 wherein the polymer is a water-insoluble polymer selected from the group consisting of polyurethanes, polyacryls, polymethacryls, urethane-acryl copolymers, styrene-acryl copolymers, and mixtures thereof.
TECHNICAL FIELD The present invention relates to kits and compositions useful as cosmetic or therapeutic agents and films formed therefrom having defined drying properties. The kits, compositions, and films herein are particularly useful as polishes for mammalian nails.
BACKGROUND OF THE INVENTION Consumers use nail polishes to cosmetically enhance their nails or protect the nails from everyday conditions and stressors. However, these nail polishes are deficient in many respects, including their inability to provide long wear. Nail polishes which are known or currently available often exhibit deterioration, particularly in the form of chipping or peeling, in as few as one or two days. The occurrence of this deterioration often forces consumers to remove their nail polish soon after original application and reapply additional nail polish to the nails. Consumers may also attempt to correct the unsightly appearance of the deteriorating nail polish by "touching-up" the areas of the nail which exhibit the deterioration, a practice which actually impairs the overall look of the nail polish. Finally, consumers may choose to do nothing about the deterioration and allow, for example, chipping and peeling to progress, resulting in nails which are not only minimally protected from the environment but are unsightly as well.
SUMMARY OF THE INVENTION The present invention relates to fast-drying nail polish compositions which, when applied to mammalian nails, exhibit rapid drying properties. The fast-drying compositions comprise:
DETAILED DESCRIPTION OF THE INVENTION The essential components of the present invention are described herein below. Also included are non-limiting descriptions of various optional and preferred components useful in the compositions and kits of the present invention.
Compositions, Kits, and Films of the Present Invention The present invention relates to fast-drying nail polish compositions which, when applied to mammalian nails, exhibit rapid drying properties. The present kits comprise two or more compositions wherein at least one of the compositions is a fast-drying composition. The kits preferably comprise a basecoat composition, a topcoat composition, and, optionally, a midcoat composition, wherein the basecoat composition is preferably the fast-drying composition. Each of the present compositions comprises a film-forming polymer, a liquid diluent, and, optionally, one or more other suitable components as described herein. As used herein, the term "film-forming polymer" means a homopolymer, copolymer, or mixture thereof which forms an adherent continuum from a composition when applied to mammalian nails. See. e.g., Polymer Colloids Robert M. Fitch, ed., New York: Plenum Press, pp. 173-183 (1971). As used herein, the term "copolymer" includes linear, block, branched, graft, comb, and star copolymers.
Preferred Kits of the Present Invention The kits herein are comprised of two or more separate and different compositions, most preferably two or three separate and different compositions. The kits herein are comprised of a fast-drying composition which is preferably a basecoat composition, and preferably, a midcoat composition and/or a topcoat composition. More preferably, the kits are comprised of a fast-drying composition, a topcoat composition, and, optionally, a midcoat composition.
Properties of the Fast-Drying Compositions The present fast-drying compositions have defined drying properties expressed by a 5% Diluent Content Time and/or an Initial Slope. Drying is a critical process in the setting of any nail polish delivered from a liquid diluent, whether it be organic solvent, water, or blends thereof. It has been discovered that the compositions having the present fast-drying property provide, for example, improved leveling, hardening, and adhesion, relative to the water-borne nail polishes and polishes comprising water which are known in the art. The compositions of the present invention exhibit:
Examples 1A-1D The compositions of Examples 1A-1D are representative of the fast-drying compositions of the present invention and are preferably applied contiguously to the nail as basecoat compositions:
Examples 2A-2E The compositions of Examples 2A-2E are suitable for use as topcoat compositions and may be applied to the basecoats of the present invention:
Example 3 The following composition may be used as either a midcoat composition or a topcoat composition.
Example 4 A kit comprising two separate nail polish compositions is prepared. The compositions are a fast-drying basecoat composition of Example 1 and a topcoat composition of Example 2. The basecoat composition is applied contiguously to mammalian nails using a standard brush-applicator. A basecoat is allowed to form. The topcoat composition is applied contiguously to the basecoat using a standard brush-applicator. The topcoat composition is allowed to form a topcoat over a five minute time period, resulting in a film having two layers.
Example 5 A kit comprising two separate nail polish compositions is prepared. The compositions are a fast-drying basecoat composition of Example 1 and a topcoat composition which is a conventional nail polish such as Max Factor� International (comprising butyl acetate, ethyl acetate, nitrocellulose, toluenesulphonamide formaldehyde resin, dibutyl phthalate, toluene, iso-propanol, camphor, benzophenone, stearalkonium hectorite, and polyester resin). The basecoat composition is applied contiguously to mammalian nails using a standard brush-applicator. A basecoat is allowed to form. The topcoat composition is applied contiguously to the basecoat using a standard brush-applicator. The topcoat composition is allowed to form a topcoat over a five minute time period, resulting in a film having two layers.
Example 6 A kit comprising three separate nail polish compositions is prepared. The compositions are a fast-drying basecoat composition of Example 1, a midcoat composition which is a conventional nail polish, such as Max Factor� International (comprising butyl acetate, ethyl acetate, nitrocellulose, toluenesulphonamide formaldehyde resin, dibutyl phthalate, toluene, iso-propanol, camphor, benzophenone, stearalkonium hectorite, and polyester resin) and a topcoat composition of Example 2. The basecoat composition is applied contiguously to mammalian nails using a standard brush-applicator. A basecoat is allowed to form. The midcoat composition is applied contiguously to the basecoat using a standard brush-applicator. The midcoat composition is allowed to form a layer over a period of five minutes, resulting in a film having two layers. The topcoat composition is applied contiguously to the layer formed from the midcoat composition using a standard brush-applicator. The topcoat composition is allowed to form a topcoat over a period of five minutes, providing a film having three layers.
Example 7 A kit comprising two separate nail polish compositions is prepared. The compositions are a fast-drying basecoat composition of Example 1 and the topcoat composition as set forth in Example 3. The basecoat composition is applied contiguously to mammalian nails using a standard brush-applicator. A basecoat is allowed to form. The topcoat composition is applied contiguously to the basecoat using a standard brush-applicator. The topcoat composition is allowed to form a topcoat over a five minute time period, resulting in a film having two layers.
