Description:
COMPOSITIONS AND METHODS FOR ALTERING THE APPEARANCE OF HAIR

[0001] This application claims priority under 35 U.S.C. §119 to U.S.

Provisional Application Nos. 61/557,895, 61/557,901 , 61/557,902, 61/557,903, 61/557,905, and 61/557,906, each of which was filed November 9, 201 1 , and each of which is incorporated by reference.

BACKGROUND OF THE INVENTION

[0002] Chemical treatments on human hair, such as re!axers, straighteners, waves, perms, oxidative and direct dyes, highlights, lightening compositions and bleaches, are generally known to result in hair breakage and loss, dryness, roughness and brittleness, and skin and/or scalp irritation. Such chemical treatments employ various reducing and oxidizing agents, alkalizing agents, and coloring agents that help re-shape, artificially color, decolorize, modify the color shade/tone, or enhance the appearance and color of hair. Often times, these chemical treatments are used with the application of heat and mechanical combing or brushing, which may contribute to adversely affecting the condition of the hair and the hair cuticle.

[0003] Thus, conventional and customary practice by consumers and hair dressers is to have a waiting period of at least 24 hours, preferably two weeks, in between two different chemical hair treatments in order to prevent or reduce irritation to the skin or scalp and the potential damage to hair caused by different chemical treatments within a short period of time, e.g., a few hours.

[0004] One example of the problems encountered with successively chemically treating the hair is associated with the use of chemical relaxers or straighteners before coloring the hair. Generally, when hair straightening or relaxing is immediately followed by a conventional oxidative hair color that employs hydrogen peroxide as the only and/or primary oxidizing agent, the combined use of peroxide with the ingredients in the hair straighteners and relaxers can result in significant decrease in the quality of the hair fibers, leading to increased roughness and damage to the hair.

[0005] Another problem with hair chemical treatments is that they may prevent the hair's color or shade from being lightened, bleached, dyed or altered correctly after the chemical treatment and therefore, prevent the consumer from achieving the desired lightening or shade/color effects, especially when the lightening, bleaching, coloration or color-lightening step is conducted immediately after the chemical treatment. Thus, a waiting period of at least 24 hours is generally recommended in order to reduce the chance of having a reaction between the different chemical treatments, for example, straightening then bleaching the hair, that could potentially result in an undesirable hair color or shade.

[0006] In order to address the concerns mentioned above, methods and compositions have been proposed such as those that involve the use of alternative ingredients and/or ingredients and compositions that are less harsh on hair and skin, including hair treatment regimens that may minimize the problems arising from successive chemical treatments. However, there still exists a need to improve such methods and compositions in order to formulate color-lightening products and hair treatment regimens or systems that allow the consumer to successively chemically treat hair in a convenient and efficient manner, which effectively alter the color of and/or re-shape the hair while minimizing the damage to the hair and other adverse effects to the consumer.

BRIEF SUMMARY OF THE INVENTION

[0007] The present disclosure is directed to methods and compositions for altering the appearance of hair. Exemplary methods comprise applying a pre- alkalizing composition to the hair, applying a color-lightening composition to the hair, and subsequently applying a coloring composition to the hair. In at least certain exemplary embodiments, the methods and compositions described allow for successive chemical treatments of the hair, while minimizing damage to the hair and/or skin (e.g. scalp).

[0008] By way of example, there is a need to provide methods and compositions that provide for hair to be chemically treated (e.g. straightened), and then subsequently lightened and colored, while achieving a desired change in hair tone and minimizing damage to the hair. Lightening of the hair is typically evaluated by the tone height or level which describes the degree or level of lightening. The notion of "tone" is based on the classification of the natural shades, one tone separating each shade from the shade immediately following or preceding it, which is well known to hairstyling professionals. The tone heights or color levels range from 1 (black) to 10 (light blond), one unit corresponding to one tone; thus, the higher the number, the lighter the shade.

[0009] Accordingly, in various exemplary embodiments of the disclosure, the methods and compositions described allow one to achieve a desired level of color and level of color "lift" in tone, i.e. to a higher number, while minimizing damage to the hair and/or skin.

[0010] Various exemplary methods according to the disclosure comprise:

(a) applying onto the hair, a pre-alkalizing composition having a pH of from about 8 to about 14 to form pre-alkalized hair;

(b) optionally, rinsing the hair;

(c) applying a color-lightening composition onto the pre-alkalized hair, wherein the color-lightening composition comprises, in a cosmetically acceptable carrier, at least one oxidizing agent chosen from peroxides, persulfates, perborates, percarbonates, peracids, bromates, their salts and mixtures thereof,

wherein the pH of the color-lightening composition ranges from about 1 to about 7;

(d) leaving the color-lightening composition on the hair for a time period sufficient to achieve a desired level of color lift;

(e) optionally, rinsing the hair;

(f) applying a coloring composition onto the hair, wherein the coloring composition comprises, in a cosmetically acceptable carrier, at least one dye compound chosen from;

(i) oxidative dye precursors, and

(ii) direct dye compounds; and

(g) rinsing the hair.

[0011] Optionally, the color-lightening compositions according to various embodiments of the disclosure may further comprise at least one additional ingredient chosen from fatty substances, de-dusting agents, alkoxyaminosilicones, silane compounds, ceramide compounds, and metal catalyst compounds.

[0012] In various embodiments, the at least one color-lightening composition may comprise a bleach composition and a developer composition.

[0013] In further embodiments, methods for minimizing damage to the hair during a process for altering the color of the hair are disclosed. Compositions useful for altering the appearance of the hair, and for minimizing damage to the hair, are also disclosed.

[001 ] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention as claimed. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the

embodiments disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the invention being indicated by the claims.

[0100] It is also to be understood that, while in various embodiments described herein, steps of exemplary methods are recited in a particular order, it is intended that the disclosed steps may be carried out in any order such that the properties intrinsically associated with the methods are not, or are not substantially, adversely affected.

DETAILED DESCRIPTION

[0015] Exemplary embodiments of the disclosure comprise applying a pre- alkalizing composition to the hair, and subsequently applying a color-lightening composition to the hair.

PRE-ALKALIZING COMPOSITION

[0016] Various embodiments of the present invention provide for applying a pre-alkalizing composition to the hair in a first step of the methods described herein. By first applying a pre-alkalizing composition to the hair, the hair is in a pre-alkalized form prior to further chemical treatments. Without wishing to be bound by theory, it is believed that the pre-alkalizing step opens the hair cuticle, thereby rendering it more susceptible to penetration by the subsequently-applied composition. This in turn is believed to render the hair coloring, straightening, relaxing, etc., process more efficient and less time-consuming, while minimizing damage.

[0017] The pre-alkalizing step may, for example, use an alkaline composition having a pH ranging from about 8 to about 14, such as about 8 to about 10.5, or about 8.5 to about 9.5. Acceptable alkaline compositions useful herein are known in the art. By way of example, any conventional base, whether alkaline hydroxide or non-hydroxide, may be chosen as the pre-alkalizing composition, so long as it results in the formation of a pre-alkalizing composition having the above-disclosed pH range. The precise amount of conventional base used will depend on the specific base or bases chosen, which can be determined through routine experimentation by those of ordinary skill in the art. The pre-alkalizing composition may further comprise a cosmetically acceptable carrier.

[0018] The pre-alkalizing composition may be employed in any suitable form, so long as the hair, after application of the pre-alkalizing composition, has a pH that is alkaline. Examples include, but are not limited to, an alkaline shampoo, an alkaline conditioner, or an alkaline solution in general. In further exemplary embodiments, the pre-alkalizing composition may be a chemical treatment composition that is alkaline and that causes a chemical reaction on the hair, such as, for example, relaxing, straightening, waving, perming, lightening the color, and/or permanent, semi-permanent or demi-permanent coloring of the hair. In one exemplary embodiment, the pre-alkalizing composition is in the form of an alkaline shampoo which would facilitate both the pre-alkalizing and cleaning of the hair at the same time.

[0019] In various exemplary embodiments, the pre-alkalizing composition may optionally comprise at least one auxiliary ingredient. Exemplary auxiliary ingredients useful in the pre-alkalizing composition according to various

embodiments of the disclosure include, but are not limited to, surfactants, rheology- modifying agents, chelants, fatty substances, ceramides, substantive polymers (cationic and/or amphoteric), an anhydrous and/or inert liquid, alkoxyaminosi!icones, and silanes, as well as other components typically used in cosmetic compositions, such as, for example, fragrances.

[0020] The pre-alkalizing composition may be applied to the hair and remain in contact with the hair for a period of time sufficient to form pre-alkalized hair. For example, the pre-alkalizing composition may be left on the hair for up to one hour, such as from about 5 minutes to about 50 minutes, from about 10 minutes to about 40 minutes, or from about 15 minutes to about 30 minutes. In various exemplary embodiments, the pre-alkalizing composition may be left on the hair for up to about 20 minutes, such as up to about 15 minutes, or up to about 10 minutes.

[0021] Once the hair has been pre-alkalized, the pre-alkalizing composition may, optionally, be rinsed off the hair before further chemical treatment is applied. [0022] In various exemplary embodiments, after the hair has been pre- alkalized, and optionally the pre-alkalizing composition rinsed, the hair may optionally be shampooed and rinsed before further chemical treatment is applied.

COLOR-LIGHTENING COMPOSITION

[0023] As a second step in various embodiments according to the disclosure, a color-lightening composition may be applied to the pre-alkalized hair. The color- lightening composition may, in at least certain embodiments, be in a ready-to-use form.

[0024] The color-lightening composition may, in various embodiments, be applied onto the hair within about 24 hours, such as less than 24 hours or less than hours, after the pre-alkalizing step. In at least certain exemplary embodiments, the color-lightening composition may be applied to the hair within a few hours (e.g. about 1 to about 6 hours) or a few minutes (e.g. up to about 60 minutes) after the pre-alkalizing step.

[0025] According to various embodiments, the color-lightening composition comprises, in a cosmetically acceptable carrier, at least one oxidizing agent chosen from peroxides, persulfates, perborates, percarbonates, peracids, bromates, their salts and mixtures thereof. The at least one oxidizing agent may, optionally, be water-soluble.

[0026] Optional peroxides useful herein include, for example, hydrogen peroxide, magnesium peroxide, PVP-peroxide, calcium peroxide, and sodium peroxide.

[0027] Exemplary, non-limiting persulfates include potassium persulfate, sodium persulfate, and ammonium persulfate. In various embodiments, exemplary oxidizing agents may be chosen from sodium perborate and sodium percarbonate. In further embodiments, exemplary peracids may be chosen from organic peracids having the general formula (I):

R-C(0)OOH wherein, in formula (I), R is chosen from saturated or unsaturated, substituted or unsubstituted, straight or branched chain, alkyl, aryl or alkaryl groups having from 1 to 22 carbon atoms. In at least some exemplary embodiments, mixtures of two or more oxidizing agents chosen from persulfates, perborates, percarbonates, peracids, bromates, and salts thereof, may be chosen.

[0028] In various embodiments, the at least one oxidizing agent is chosen from alkali metal salts of perborates, percarbonates, bromates, and persulfates, such as, for example, ammonium, sodium, and potassium salts.

[0029] The color-lightening composition may also comprise a cosmetically acceptable carrier. The cosmetically acceptable carrier may, for example, be present in the color-lightening composition in an amount ranging from about 1 % to about 40% by weight, such as from about 5% to about 35% by weight, or about 10% to about 30% by weight of the color-lightening composition.

[0030] Auxiliary ingredients may be added to the color-lightening

composition. Exemplary auxiliary ingredients useful in the color-lightening
