The contents of all of the above-mentioned applications are incorporated herein by reference in their entirety.


BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to compositions, kits and methods for treating hair. More particularly, the present invention includes compositions, kits and methods for treating hair using compounds described below, but without agents for effecting polymerization.
The present invention also provides novel compositions that allow for long-lasting moisture resistance, that are more repellant to dirt particles than natural hair while simultaneously leaving much less residue and producing long-lasting shine.
Background of the Invention
The hair care industry is a multi-billion dollar industry in the United States alone. The industry includes the development, production, and marketing of a large array of products for hair care, including shampoos, gels, mousses, lotions, sprays, conditioners, coloring products, pomades, serums, waxes, and repair products. Most of these products utilize pre-formed polymers developed to impart a desired characteristic upon application to a user's hair. For example, polymers are used to give hair shine, style hair, preserve hair style, give hair a desired texture or feel, enhance hair color, condition hair, dry hair so it sets quickly, straighten or smoothen hair, soften hair, strengthen hair, make hard-to-treat hair manageable, enhance optical properties, provide hold to hair, provide frizz control and/or to repair damaged hair.
Some of the above-identified beneficial attributes have been afforded in existing hair care products through use of compositions containing conditioning agents such as silicones or other polymers, which have a high affinity for keratin and especially for scalp hair. Such compounds include, but are not limited to silicones such as cyclomethicone, dimethiconol, dimethicone, cyclopentasiloxane, cyclomethicone, trimethylsiloxyphenyl, dimethiconol, cyclopentasiloxane dimethicone copolyol. However, the coating on keratin fibers, such as the hair, obtained with such compositions often has an unpleasant tacky feel and also may be readily lost via transfer, for example when a hand is passed through the hair. In addition, as a result of such transfer the hair may give the impression of being dirty, sticky or tacky. Also, the effects of the use of such silicone compounds and polymers is not long lasting as they are removed by shampooing the hair, thus making it necessary to repeat application of the compositions to the hair, for example, after rinsing, washing or shampooing.
Attempts have been made to treat hair with certain acrylate monomers and polymerize them in situ by free-radical polymerization. For example, U.S. Pat. No. 3,676,550 discloses use of certain acrylate and methacrylate compositions as hair treatments. Those compositions employ an “inert solvent” (which contains 10 to 90% water; the remainder being water-miscible organic solvent).
Unfortunately, compositions and methods that employ in situ free radical polymerization tend to degrade the hair, since harsh chemicals are involved. Another problem reported for such compositions and methods is that the chemicals employed irritate and/or are harmful to the hair and/or skin and leave the hair feeling harsh, as well as causing hair discoloration. Furthermore, many such hair treatments may involve reduction of hair prior to treatment, which causes additional hair damage.
One approach to avoid the harsh chemicals and/or conditions involved in in situ polymerization has been to avoid monomers that do not require such initiators, but rather employ monomers that readily polymerize in the presence of moisture (water). Accordingly, U.S. Pat. No. 5,082,010 shows that cyanoacrylates have been used as a treatment for hair. Cyanoacrylate monomers readily polymerize in the presence of moisture and are said to be “instant adhesives.” “Crazy Glue” (2-cyano acrylate) is such an example. In addition, a medical glue, 2-octyl cyanoacrylate, is FDA approved for use as a wound adhesive for use in surgery. Contact with the moisture in the air, or from a biological fluid or tissue, is sufficient for polymerization of such cyanoacrylates.
Thus, existing hair care treatments suffer from numerous technical limitations. In addition to these technical limitations, there are functional limitations and drawbacks of using existing hair care formulations. One problem common to many hair care products is poor efficacy and longevity. For example, existing hair care treatments are not robust and can lose their efficacy over the course of a day. Many treatments lose their efficacy upon exposure to water or excess humidity. In addition, many hair treatments weigh down hair, flake off, leave unsightly residues, fail to dry and set quickly, do not provide adequate hold, and are not effective for hard-to-treat hair (e.g., naturally curly hair). Treatments have been developed which overcome some of these issues; however, they typically involve permanently treating the hair with reducing and/or oxidizing agents which can damage hair. Thus, there remains a need for hair treatments that withstand the rigors of a typical user's daily routine and maintain efficacy in a variety of environments without damaging hair fibers. It is preferable that a hair treatment be long lasting, not weigh down hair, not flake, and not leave any undesirable residues. Furthermore, the hair treatment should preferably dry and set relatively quickly, provide adequate hold, and be able to manage hard-to-treat hair.
SUMMARY OF THE INVENTION
As described herein, it has been discovered that certain organic chemical compounds, applied to hair, produce effects and characteristics desired by hair product consumers. The compounds are preferably not polymers such as those typically used in hair care products. The compounds are fluorinated but are not perfluorinated. In certain embodiments, a combination of compounds described herein are used to treat hair. The compositions, kits and methods of the present invention afford numerous beneficial effects that are especially desired for treating scalp hair, including: (1) controlling moisture penetration into the hair (frizz control), (2) providing a soft feel to the hair, without a harsh feeling (conditioning), (3) increasing the shine of the hair, (4) enhancing the hair's color, (5) avoiding the feeling of stickiness to the hair (and consequently resisting accumulation of dirt to the hair), (6) dries and sets quickly, (7) can help generate and or preserve the style of the hair, (8) adding strength to the hair, (9) leaving a low amount of residue (are “weightless”), (10) do not flake off the hair, (11) lasting over the course of more than one day, even more than 5 days, (12) affecting, including reducing, the surface energy of the hair (and thereby affording quicker drying of hair), (13) affording manageability for hard-to-treat hair, as well as repairing damaged hair, (14) providing hold, and (15) providing shape.

Cosmetic Hair Care Compositions
The present invention provides cosmetic hair care compositions comprising an active hair care ingredient as described above, and a cosmetically acceptable excipient. Cosmetically acceptable excipients used in the hair care industry can be broken down into several categories. Components from a category may be included or excluded from the final hair care composition depending on the use of the final composition (e.g., hair spray, conditioner, shampoo). The categories of excipients include: (1) preservatives/antioxidants/chelating agents; (2) sunscreen agents; (3) vitamins; (4) dyes/hair coloring agents; (5) proteins/amino acids; (6) plant extracts; (7) humectants; (8) fragrances/perfumes; (9) oils/emollients/lubricants/butters; (10) penetrants; (11) thickeners/viscosity modifiers; (12) polymers/resins/hair fixatives/film formers; (13) surfactants/detergents/emulsifiers/opacifying agents; (14) volatiles/propellants/solvents/carriers; (15) liquid vehicles/solvents/carriers; (16) salts; (17) pH adjusting agents/buffers/neutralizing agents; (18) hair conditioning agents; (19) anti-static agents/anti-frizz agents; (20) antidandruff agents; (21) hair waving/straightening agents; and (22) absorbents.

In certain particular embodiments, the composition comprises water, an alcohol, an oil, a polymer, fragrance, and an active hair care ingredient. In certain particular embodiments, the composition comprises water, an alcohol, an anti-static agent, fragrance, and an active hair care ingredient. In certain particular embodiments, the composition comprises water, an alcohol, a hair-conditioning agent, fragrance, and an active hair care ingredient. In certain particular embodiments, the composition comprises water, an alcohol, a surfactant, fragrance, and an active hair care ingredient. In certain particular embodiments, the composition comprises water, an alcohol, an emollient, fragrance, and an active hair care ingredient. Hair spray compositions are dispensed from containers that aerosol dispensers or pump spray dispensers. Such dispensers are known in the art and are commercially available from a variety of manufacturers, including American National Can Corp. and Continental Can Corp.
In certain embodiments, when the hair spray composition is dispensed from a pressurized aerosol container, a propellant is used to force the composition out of the container. Suitable propellants are described herein. In certain embodiments, the propellant is a liquifiable gas. In certain embodiments, the propellant is a halogenated propellant. In other embodiments, the composition does not contain any fluorinated or chlorinated propellants. Generally, the amount of propellant in the composition is from about 10% to about 60% by weight. In certain embodiments, the amount of propellant in the composition ranges from about 15% to about 50% by weight. In certain embodiments, the propellant is separated from the hair spray composition as as in a two compartment container. Other suitable aerosol dispensers are those characterized by the propellant being compressed air which can be filled into the dispenser using a pump or equivalent device prior to use. Such dispensers are described in U.S. Pat. Nos. 4,077,441 and 4,850,577, both of which are incorporated by reference herein, and in U.S. patent application, U.S. Ser. No. 07/839,648, filed Feb. 21, 1992, also incorporated by reference herein. Conventional non-aerosol pump spray dispensers, i.e., atomizers, may also be used to apply the invention hair spray compositions. In certain embodiments, when the hair spray composition is dispensed from a pressurized aerosol container, the container is essentially propellant-free and uses a ‘bag or bladder’ in bottle to apply the invention.

Other rheology modifiers and non-ionic emulsifiers not specifically mentioned above are commercially available and known to those of ordinary skill in the art. Other excipients, suitable for hair care products, may be added to the non-alcohol spray to achieve desired functionality.
Moisture Resistance
Moisture on hair and its penetration into the hair can disturb the arrangement of hair proteins, resulting in cosmetically undesired changes, such as, an increase of frizz. The present invention provides hair, in particular hair on or from the scalp, with beneficial moisture resistance properties. Moisture resistance in the present invention refers to the hysteresis of water sorption/desorption when measured by Dynamic Vapor Sorption (DVS). In DVS a sample is placed on a microbalance exposed to a continuous flow of air with predetermined and constant relative humidity. As the humid air passes over the sample, a zone of constant moisture concentration is created around it. This zone allows the rapid establishment of water vapor sorption or desorption equilibrium by maximizing mass transport of water vapor into and out of the sample.
Mass changes in the sample (e.g., a swatch of hair) due to water vapor sorption/desorption can be measured between different levels of relative humidity at a particular temperature. The change in mass can be plotted as a function of the relative humidity, which provides information about the nature of water vapor sorption phase (absorption and/or adsorption) when humidity is increased, or, conversely, the nature of desorption of water, when humidity is decreased. The difference in changes in mass at any particular value for relative humidity in the sorption and desorption phases is known as the hysteresis and can be used as a measure to evaluate the ability of a hair treatment to resist or control moisture on and in hair. As described below, the invention affords reduced hysteresis especially over relative humidity values range of 30-80% RH.
In the context of the present invention, moisture resistance is measured according to DVS Protocol I. A “decrease in moisture flux” means that treated hair exhibits a decrease in hysteresis when subjected to dynamic vapor sorption according to DVS Protocol I.
DVS Protocol I
1. 1.50 g of bleached hair tress (standard single bleached, wavy frizzy hair from International Hair Importers, White Plains N.Y., USA) is dampened with 0.30 mL de-ionized water, optionally via pipet, and lightly combed through to remove any tangles.
2. Apply composition to the hair tress according to the following amounts: for a serum (0.09 g to 0.12 g), for a cream/lotion/mousse (0.20 g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributed evenly and combed through the hair. Preferably the weight ratio of formulation to hair should be approximately 0.073 for serums, 0.15 for a cream/lotion/mousse and 0.25 for a spray.

3. Styling consists of 10 passes with a hair brush and blow drier set to high, approximately 50-120° C.

4. After styling, the hair is cut and sections from the middle of each tress (approximately 300 mg) are analyzed via DVS.

5. DVS conditions are as follows. Unless otherwise stated the temperature employed is 25° C. Sorption phase: Start at 30% RH and increase up to 90% RH, each step increasing RH by 10%. Desorption phase: Start at 90% RH and decrease down to 0% RH, each step decreasing RH by 10%. At each RH condition, the sample is maintained for 4 hours, and the step up or down to the next RH level is programmed to occur over 20 min period.

Monitoring the hysteresis values from such a DVS experiment on hair samples allows assessment of the ability of a hair treatment to resist or control moisture.
The present invention affords superior moisture resistance compared to either (1) a control treatment using water and (2) a silicone product, such as Kérastase® Oleo Relax Serum (purchased in the USA, 2008; hereinafter “Commercial Example A”), which in fact increased the hysteresis compared to water. Preferably, use of the invention on a hair tress as described above affords a 4% reduction in the average hysteresis values compared to control (water-treated) hair over the relative humidity range of 30-80% when examined by the DVS protocol described above. More preferably, use of the invention on a hair tress as described above affords more than a 10% reduction and still more preferably more than a 20% reduction, in the average hysteresis values compared to control (water treated) hair over the relative humidity range of 30-80% when examined by the DVS protocol described above. Even more preferably, the invention affords a 50% or more, or even an 80% or more, reduction in the average hysteresis values compared to control (water-treated) hair over the relative humidity values range of 30-80% RH when determined by the DVS protocol described above.
Weightlessness
Those who use hair care products desire the beneficial effects described above. However, such users do not want the feeling of residue/product in or on their hair. A composition that maintains performance, but which does so with less residual weight or “feel” in the hair is, therefore, preferred.
The compositions of the present invention, while maintaining product performance, beneficially lose no less than 25% of their weight, preferably 50% of their weight, more preferably no less than 70% of their weight, still more preferably no less than 80% weight, and still more preferably no less than 90%, and most preferably 95% or higher of their weight after heating at 55° C. and 10% RH for 10 minutes (for spray formulations) and 30 minutes (cream/lotion/serum/mousse) formulations according to the “Weightlessness Test I.”
Weightless Test I
Composition is dispensed into an uncovered container and spread out evenly. For instance, the container is a round container with a diameter of 9 cm and a lip measuring 0.5 cm.
1. The containers are labeled and then weighed immediately before and after dosing with 3 g of formulation.
2. Compositions are left to equilibrate at ambient conditions (25° C., 30% RH) for 5 minutes before placing into the oven.
3. The container is placed into an oven controlled at 55° C. and 10% RH.
4. Each dish is removed and its mass recorded at 10 minutes for spray compositions and 30 minutes for cream/lotion/serum/mousse compositions.
The compositions for treating hair according to the invention on average leave at least 25% less residue upon dry-down when following package instructions for amounts used for Kérastase® Oleo Relax Serum (“Commercial Example A”), John Frieda® Frizz Ease (“Commercial Example B”), Biosilk® Silk Therapy (“Commercial Example H”), Redken® Smooth Down Heat Glide (“Commercial Example C”), Nexxus® Sleek Memory Straightening Smooth Spray (“Commercial Example D”), Barex® Re-define Crème (“Commercial Example G”), Fekkai® Glossing Cream (“Commercial Example E”) and Bedhead® Curls Rock (“Commercial Example F”) (all purchased in the USA; 2008). It is believed that one reason for the “weightlessness” benefits of the inventive formulations is that they do not require, and preferably do not include, silicone compounds at levels found in the above identified hair care products.
Dirt Resistance
Many materials are used to control or reduce moisture penetration into hair fibers. However, the majority of these materials are oil-based or silicone-based. The resulting effect is modest moisture resistance combined with a heavy residue feel which attracts grease and particulates. It is desirable in the art to create a composition that will control or reduce moisture penetration into hair fibers while leaving the hair feeling lightweight, non-greasy, and minimizing attraction of dirt/particulates.
The attraction of dirt and particles to the hair leaves the hair limper, heavier, and duller throughout the day. The ability to resist environmental pollutants gives the hair longer lasting style and shine. Accordingly, the ability of the present inventive hair care compositions to resist dirt accumulation was examined and compared to Commercial Example A. Corn starch was selected as simulated dirt. USP corn starch is uniformly-white and can associate with hair, providing excellent contrast on black hair, thereby allowing for a quantifiable Gray-scale measurement via digital photography. Remaining corn starch was also assayed by gravimetric analysis.
Starch Resistance (Gravimetric)
The inventive hair care compositions when tested on hair as described below should afford gain in weight of no more than 15% by weight, preferably no more than 10% by weight, more preferably no more than 7% weight, and most preferably no more than 5% by weight when subjected to Starch Test I. As a measure of resisting dirt, “weight gain” refers to the weight gain measured according to Starch Test I.
Starch Test I
1. 1.50 g of virgin dark brown hair tress (International Hair Importers, White Plains N.Y., USA) is dampened with 0.30 mL of water, optionally via pipette.
2. Apply composition to the hair tress according to the following amounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20 g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributed evenly and combed through the hair. Preferably the weight ratio of formulation to hair should be approximately 0.073 for serums, 0.15 for a cream/lotion/mousse and 0.25 for a spray.

3. The hair was styled with a hair brush and blow drier on high speed and high temperature, approximately at 50-120° C. for 30 seconds.

4. The tress is saturated in a bath of corn starch, for instance, in about 2 grams of corn starch, USP.

5. The tress is removed from the corn starch bath and shaken by hand until all loose corn starch is removed, for instance, for 10 seconds.

6. The tress is weighed and the new mass is recorded.

The present invention may be used on any animal with hair. The system is particularly useful for treating human hair. However, the hair or fur of other mammals may also be treated. For example, the hair or fur of domesticated animals such as dogs and cats may be treated using the inventive system. In addition, the hair or fur of test animals such as rodents (e.g., mouse, rat, rabbit, guinea pig, etc.) or primates may also be treated. In certain embodiments, hair samples from a human (e.g., hair clippings) or other animals are tested with the present invention. Hair or fur samples treated with the present invention are considered to be within the scope of the invention. These hair or fur samples comprise compound on the hair or fur. In certain embodiments, the hair is human hair. In other embodiments, the hair is non-human hair. In certain embodiments, the hair or fur is dog or cat hair or fur. In other embodiments, the hair is rat, mouse, guinea pig, rabbit, gerbil, or primate hair. The hair treatment system of the present invention can also be used to treat hair contained in wigs, toupees, and hairpieces.
These and other aspects of the present invention will be further appreciated upon consideration of the following Examples, which are intended to illustrate certain particular embodiments of the invention but are not intended to limit its scope, as defined by the claims.
EXAMPLES
Example 1—Testing of Treated Hair
Tests as described herein may be used to test shine/luster, break strength, and hair fiber thickness.
In this example, the measure of the hair's shine/luster is proposed. After applying a composition and curling and brushing a hair sample, the hair would be wound around a cylinder and placed under a lamp that mimics sunlight. The width of the cone of luster will be measure and compared with that of a commercial product.
In this example, the measure of the hair's break strength is proposed. Single hair fibers (treated and untreated) can be attached to an Instron which will pull at one end of the fiber, breaking the fiber at a certain force.
In this example, the measure of the hair fiber thickness is proposed. Cross sections of hair fibers (treated and untreated) can be examined and measured by microscopy.
In this example, the humidity resistance of the treated hair is proposed. This property can be measured by placing the styled hair tress in an atmosphere of high humidity.
In this example, the feel is proposed. The parameters of feel can be assessed for a given material on the hair fiber. Several parameters such as tack, slip, stiffness, smoothness, grease, and strength can be evaluated by a blind test of experts.

Example 18—Non-Alcohol Aqueous Styling Spray Gel
The fluorinated compound was first preblended with a non-ionic emulsifier. Preblending of the emulsifier and fluorinated compound ensures proper formation of the suspended emulsion droplets resulting in a single or multi bi-layer coating of the fluorinated compound. The concentration of emulsifier remained under the CMC (critical micelle concentration) as micelle formation does not improve the stability of the suspension. The composition was homogenized such that the droplet size was less than 15 microns. This allows for lower oil to emulsifier ratio, proper dispersion of the suspended droplets and stability of the composition. The result was an aqueous based suspension of coated fluorinated compound, which resists coalescence, flocculation, and/or phase separation of the fluorinated compound. Applying shear to the compositor (e.g. spray pump), reduces the viscosity and allows for delivery of the fluorinated compound via a uniform spray pattern. Removal of the shear, allows the viscosity to recover and the composition to stabilize.

The fluorinated compound and fragrance were then added to the vessel. The contents were mixed until homogeneous. Phase B was added to Phase A and they were mixed until homogeneous. The mixture was then homogenized to reduce the particle size to 5-15 microns, then mixed slowly with a pitched blade propeller and allowed to de-aerate. Phase C consisting of the remaining Lubrajel II XD and a preservative: Components of Phase C were then added to the above mixture of Phase A and Phase B and mixed for 1 hour. The mixture was then cooled to 21° C.-25° C.
Example 20—Non-Alcohol Aqueous Styling Spray Gel
To further stabilize a non-alcohol aqueous styling spray gel containing a fluorinated compound with a specific gravity greater than 1.00, a low specific gravity material, such as a paraffin blend, may be added to the composition. The addition of the lower specific gravity material balances the oil phase specific gravity to 1.00, allowing for greater suspension stability.

As discussed under “Moisture Resistance” above, differences in water adsorption/desorption at a particular relative humidity (the “hysteresis”) can be used as a measure to evaluate the ability of a hair treatment to resist or control moisture on and in the hair. In FIG. 1, the lower overall hysteresis values for the Hair Spray A treated samples indicate that less water was able to adsorb onto and penetrate into the hair that for the Commercial Example A-treated samples. This is in line with the hypothesis that the invention creates a vapor barrier on the hair fiber. On the other hand, the Commercial Example A-treated samples behave very similarly to the water-treated samples demonstrating poor vapor barrier function. In fact, the 5 treatment Commercial Example A sample with multiple shampoos performed worse than the water treated sample. This is may be a result of the shampooing increasing the hair's porosity and the inability of Commercial Example A treatment to provide an adequate barrier to protect the hair fibers. As seen in FIG. 1, multiple applications of Hair Spray A increased moisture resistance while the silicone-based Commercial Example A did not demonstrate any resistance versus the water-treated sample at 60% and 80% relative humidity.
Comparative Example 2—Weightlessness
The residue and overall weight of preferred embodiments of the present invention were compared to leading, silicone-based commercial products using the Weightless Test I protocol discussed above. The amounts of products used (based on package instructions) are shown in Table 2. Formulations were incubated in an oven either for 10 minutes (sprays and serum products) or for 30 minutes (cream products) at 55° C., and the mass remaining was determined.
