Patent Application

According to the International Cosmetic Ingredient Dictionary and Handbook, Tenth Ed., 2004 (herein incorporated by reference in its entirety) hair colorants (e.g., materials which impart color to hair) are classified as temporary, semi-permanent, permanent or progressive.
Temporary hair colorants include color rinses, which provide color that lasts until the first shampooing. Ingredients which impart temporary color may have a fairly high molecular weight and are unable to penetrate the hair shaft. These materials are simply deposited onto the hair fiber and are removed by subsequent shampooing.
Direct dyes generally provide color through several shampooings. These materials are either low molecular weight pre-formed colored compounds that can penetrate the hair shaft to some extent or larger molecular weight colored compounds that interact with the surface of the hair fiber via non-covalent interactions.
Oxidative dyes are considered permanent hair coloring preparations as they provide color that is not substantially removed by shampooing. Oxidative coloration involves the deposition of an essentially colorless intermediate and of a coupling agent inside the hair fiber. In the presence of an oxidizing agent, usually hydrogen peroxide, these chemicals form a series of complex colored dyestuffs inside the hair fiber. Progressive hair coloring preparations are oxidative hair colors which develop color gradually by repeated applications.
While oxidative dyes may be preferred due to their long-lasting coloration, they have some disadvantages to direct coloring preparations. For example, direct dyes are more vibrant and provide a more “pure” color than do the oxidative dyes. It will be appreciated by those skilled in the art that the “pure” color of direct dyes is due to generally higher extinction coefficients and narrower peak widths at half height than oxidative dyes. Oxidative dyes can also participate in side reactions during the application process that can affect the final hair color and perform less well on damaged hair. Therefore, it would be desirable to develop non-oxidative dyes with the color and vibrancy of a direct dye and the long lasting color fastness of an oxidative dye that optionally performs better on damaged hair than on non-damaged hair.
The present invention is based, at least in part, on the discovery that certain functionalized, non-oxidative dyes exhibit an enhanced color fastness and vibrancy compared to other dyes (e.g., oxidative dyes and/or direct dyes). Therefore, it is an object of the present invention to provide such dyes and compositions thereof, as well as methods of using such dyes and kits comprising the same.
Accordingly, in one aspect, the present invention provides a functionalized dye comprising at least one chromophore and a color fastness moiety, wherein the chromophore is bound to the color fastness moiety by a linker, wherein said functionalized dye has an enhanced color fastness compared to a non-functionalized direct dye.

In order to more clearly and concisely describe the subject matter of the claims, the following definitions are intended to provide guidance as to the meaning of terms used herein.
As used herein, the articles “a” and “an” mean “one or more” or “at least one,” unless otherwise indicated. That is, reference to any element of the present invention by the indefinite article “a” or “an” does not exclude the possibility that more than one of the element is present.
It should be noted that the terma “dye” and “compound” may be used interchangeably.
In some aspects, the present invention provides functionalized dyes. The language “functionalized dye” includes dyes having at least one chromophore that has been chemically modified. The language “non-functionalized dye” includes dyes that have at least one chromophore that has not been chemically modified. In some embodiments, the non-functionalized dye is a chromophore, C, as defined below.
In other aspects, the present invention provides damage selective dyes. The language “damage selective dye” includes dyes that perform better on damaged hair than normal hair (e.g., undamaged hair). The term “damaged hair” includes hair that is more porous than normal hair due to chemical exposure (e.g., bleaching or overdying hair, exposure to chemicals in swimming pools or minerals in groundwater), prolonged or repeated heat exposure (e.g., through the use of heat styling tools or excessive sun exposure), prolonged UV exposure, excessive perming and straightening of hair or a genetic predisposition to having more porous hair. In one embodiment, damaged hair includes hair with split ends. The language “normal hair” includes hair that is of normal porosity (e.g., undamaged hair) and may include unbleached or uncolored hair.
In some aspects, invention provides non-oxidative dyes. The language “non-oxidative dye” includes dyes that are pre-formed before application on the hair and do not require a coupling agent or an oxidizing agent to form the dye after deposition on the hair. In contrast, the language “oxidative dye” includes dyes that are formed by the application of an intermediate, a coupling agent and an oxidizing agent onto the hair such that the intermediate and coupling agent penetrate the hair and undergo a chemical reaction to form a colored dye within the hair.
In some embodiments, the dyes of the invention have a greater color fastness than a semi-permanent dye (e.g., a level 2 dye or a dye that lasts for about 5-8 shampoos). In some embodiments, the dyes of the invention have a greater color fastness than a permanent (e.g., a level 3 dye or a dye that last for about 9 or more shampoos). The language “greater color fastness” includes the ability of the dye to have an improved resistance to color change or color fading after application to hair when compared to a direct dye or an oxidative dye of substantially the same color.
In some embodiments, the dye is retained and imparts color on hair after application to the hair. The language “retained and imparts color” includes the ability of the dye to remain on the hair and provide the desired color with substantially no change in color or fading of color after a period of time compared to a direct dye or an oxidative dye of substantially the same color and after substantially the same period of time, as measured by the visual inspection assay described in Example 4. In some embodiments, the dye is retained and imparts color on hair after application to the hair at least about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95% or about 100% longer than a direct dye or an oxidative dye of substantially the same color.
In other embodiments, the dye has greater vibrancy after application to hair. The language “greater vibrancy” includes the ability of the dye to provide a brighter color after application to hair compared to an oxidative dye, as measured, for example, by the visual inspection assay described in Example 4 or by a colorimeter. In some embodiments, the dye provides vibrancy that is about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95% or about 100% greater than an oxidative dye of substantially the same color.
In other embodiments, the dye maintains its vibrancy after application to hair. The language “maintains vibrancy” includes the ability of the dye to retain its brightness after a period of time compared to an oxidative dye of substantially the same color after substantially the same period of time, as measured by the visual inspection assay described in Example 4. In some embodiments, the dye maintains its vibrancy by about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95% or about 100% longer than an oxidative dye of substantially the same color.
In some embodiments, the dyes of the invention are non-ionic (e.g., the dyes do not have a positive charge (e.g., non-cationic) or negative charge (e.g., non-anionic)). Examples of anionic and cationic dyes include, but are not limited to, those in Table 1.
In some embodiments, the dye is fluorescent.
In other embodiments, the dye is a non-natural dye (e.g., a dye obtained from a natural source, for example, a plant, animal or mineral). Examples of dyes obtained from natural sources include, for example, indigo, carminic acid, lawsone (e.g., henna), lycopene, madder, monascus derivatives, santalin, annatto, apigenin, canthaxanthin, capsanthin, capsorubin, carotenes, carthamin, crocin, crocetin, curcumin, lutein, luteolin, pratol, caramel, cocoa, chlorophyll and indigo.
In still other embodiments and without being bound by theory, the dye interacts with hair by non-covalent interactions after application to the hair. Examples of non-covalent interactions include, for example, hydrogen bonding, pi stacking, van der Waals interactions, hydrophobic interactions and dipole-dipole interactions.
In some embodiments, the dye is a functionalized oxidative dye precursor or intermediate that is capable of further reactive chemistry inside the hair fiber typical of oxidative dyes (e.g., functionalized para-phenylene diamine) such that the final reacted dye has longer lasting color than the non-functionalized dye.
In one embodiment, the dye is of formula Ia:
C-L-F (Ia)
wherein
C is a chromophore,
L is a linker and;
F is a color fastness moiety and cosmetically acceptable salts thereof.
In other embodiments, the dye is of formula Ib:
C-L-F-L*-C* (Ib)
wherein
C and C* are each the same or a different chromophores;
L and L* are linkers; and
F is a color fastness moiety, and cosmetically acceptable salts thereof.
The term “chromophore” includes chemical moieties that are capable of providing color to the dyes of the invention. In some embodiments, the chromophore is a colored moiety prior to being covalently linked to L and/or L* and/or F. In other embodiments, the dye resulting from covalently linking L and/or L* and/or F to C or C* when C or C* is a colored moiety provides a molecule with the same or a different color than C or C*. In some embodiments, when C or C* are non-colored molecules, the covalent bonding of C or C* to L and/or L* and/or F result in a colored molecule.
In some embodiments, the chromophore (e.g., C or C*) is selected from the group consisting of an anthraquinone chromophore, an arylmethane chromophore, a diarylmethane chromophore, a diphenyl methane chromophore, a triarylmethane chromophore, an azo chromophore, a cyanine chromophore, a diazonium chromophore, a nitro chromophore, a nitroso chromophore, a phthalocyanine chromophore, a quinone-imine chromophore, an azin chromophore, an eurhodin chromophore, a safranin chromophore, an indamin chromophore, an indophenol chromophore, an oxazin chromophore, an oxazone chromophore, a thiazin chromophore, a thiazole chromophore, a xanthene chromophore, a fluorine chromophore, a pyronin chromophore, a fluorine chromophore, a rhodamine chromophore, a substituted benzene or a derivative or a cosmetically acceptable salts thereof.

Materials: Virgin light blond, virgin light brown, virgin medium brown, and single bleached medium brown hair were purchased from International Hair Importers (Glendale, N.Y.). BW 2000 Ultra Concentrated bleaching powder, 20V Hydrogen Peroxide Pure White, and 40V Hydrogen Peroxide Pure White were purchased from Clairol Professional (Stamford, Conn.). Shampoo was a solution of 7.5% (w/w) sodium lauryl sulfate (SLS, Spectrum Chemical, Gardena, Calif.) in deionized water.
Bleaching: An amount of 1 gram of virgin hair tresses from International Hair Importers was used, which had enough thickness that when laid flat on a surface the background was not seen. The bleach paste was freshly made prior to use by mixing 5.57 gram per tress of the BW 2000 Ultra Concentrated bleaching powder with 10 mL per tress of Pure White 20 V hydrogen peroxide solution. The thick, lumpy white paste was spread quickly over both sides of the hair tresses, and then, the timer was started. The paste was then spread uniformly with the fingers (gloves) into the tress so that the latter was well saturated. The tress was wrapped in aluminum foil and left to stand for a total of 30 minutes at room temperature after which the tress was thoroughly rinsed with water. It was shampooed with a 7.5% SLS solution, rinsed and dried. For quick drying, the tresses were left in the humidity chamber at 20% Relative Humidity, 50° C. for 20 minutes. Blow drying was avoided so as not to entangle the hair and induce damage. The hair was also sometimes air-dried for at least 3-4 hours. The procedure was repeated up to 3 times if triple bleached hair was desired.
Color treatment: The dye bath/paste should be enough to overwhelm the hair and saturate the hair (about 5 gram paste for 1 gram hair). When several tresses were dyed at the same time, there were delay times between the application of the dyes or shampoos that may cause the tones and shades of the dyes to be different for each tress. To minimize any discrepancy in color, the dye mix was quickly spread over both sides of the tress, and the timer started. The dye was then worked through each tress and sealed in foil as quickly as possible. After the color was developed (usually for 30 minutes), the tress was thoroughly rinsed. Tresses that had dye worked through them first were rinsed first to minimize timing differences.
Color lastingness: The lastingness of the color was determined through shampooing. Multiple shampoos may be done in a row without drying in between. The wash-out experiments were done in a consistent manner. The shampoo cycles involved the hair being lathered in a controlled manner with a 7.5% (w/w) SLS solution for 15 seconds and rinsed for 15 seconds under warm water at 35 (±5)° C. This process was done 15-25 times to simulate the number of shampoos during 4-6 weeks after a consumer has dyed his/her hair.
Performance Evaluation: One gram single bleached hair tresses from International Hair Importers were (a) dyed with a leading commercial red dye or (b) treated with a non-red based commercially available kit for 30 minutes at room temperature to “lift” the hair (e.g., make the hair more porous), followed by soaking in a 0.6% (w/w) solution of compound A in a 1:1 mixture of EtOH:phosphate buffer, pH 4.5 for 10 minutes at room temperature.
Upon conclusion of the color treatment process, the tresses were rinsed until water runs clear and shampooed and rinsed once. The tresses were then shampooed, as described above. The results, shown in
In a second assay to determine the effect of the dyes of the invention on damaged hair, virgin medium blond, single bleached (commercial), 3×40 V from virgin medium brown, platinum (commercial double bleached), 6×40 V from Virgin medium brown, and 9×40 V from virgin medium brown were (a) dyed with either the leading commercially available red dye (1 g of dye cream to 1 mL of 20V peroxide) for 30 minutes at room temperature or (b) treated with a blond commercially available kit such as L'Oréal Superior Preference 9½ NB or with a dyeless base prepared on site for 30 minutes at room temperature to “lift” the hair (e.g., make the hair more porous), followed by soaking in a 0.6% (w/w) solution of compound A in a 1:1 mixture of EtOH:phosphate buffer, pH 4.5 for 10 minutes at room temperature. The results, shown in
To determine the extent of color fastness and vibrancy, a number of tresses are prepared as described above in Example 3. After the tresses are dried, a visual inspection comparing the tresses with control tresses is performed to evaluate vibrancy and color fastness of the dyes. A scale from 1 to 4 is then used to rank the vibrancy and color fastness compared to the control tresses, as shown below. Additionally, compounds of the present invention were analyzed for color fastness on hair tresses using a Konica Minolta Chroma Meter CR-400 with the SpectraMagic™ NX Lite CM-S100w 1.91.0002 software package and were found to retain color after multiple shampoo cycles.
