Abstract

The present disclosure relates to hair coloring base compositions and ready-to-use hair coloring compositions comprising 2-methoxymethyl-P-phenylenediamine, an oxidative dye precursor. The hair coloring base composition is mixed with a developer composition to form a ready-to-use hair coloring composition. These compositions are effective for coloring hair. The color imparted to the hair is long-lasting (tenacious) and skin sensitivity due to the coloring process is minimized or prevented. Methods for making the composition and methods for coloring hair are also disclosed.

Description

Attorney Docket No.085137-765346 TITLE HAIR COLORING COMPOSITIONS CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Serial No.17/823,603, filed August 31, 2022, U.S. Serial No.63/402,686, filed August 31, 2022, and the benefit of French Application No. FR 2210418, filed on October 11, 2022, and French Application No. FR 2210812, filed on October 19, 2022, which are incorporated herein by reference in their entirety. FIELD OF THE DISCLOSURE The present disclosure relates to hair coloring base compositions and ready-to-use hair coloring compositions comprising 2-methoxymethyl-P-phenylenediamine, an oxidative dye precursor. Methods for making the compositions and methods for coloring hair are also described. BACKGROUND Consumers desire cosmetic compositions that enhance their appearance including the appearance of hair, e.g., by changing the color, style, and/or shape of the hair, and/or by imparting various properties to hair, such as shine and conditioning. Many of the known compositions and processes for enhancing the appearance of the hair involve chemically treating the hair. The process of changing the color of hair, for example, can involve depositing an artificial color onto the hair which provides a different shade or color to the hair, and/or lifting the color of the hair, such as lightening the color of dark hair to lighter shades. The process of lifting the color of hair, also known as lightening (or bleaching), generally requires the use of compositions that comprise at least one oxidizing agent. Lightening or lifting the color of the hair is typically evaluated by the variation in tone height before and after the application of a hair coloring composition. This variation corresponds to the degree or level of lightening or lift. 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 levels range from 1 (black) to 10 (light blond), one unit corresponding to one tone. Thus, the higher the number, the lighter the shade or the greater the degree of lift. In general, hair lightening, or color lifting compositions and hair coloring (or dying) compositions have a pH value of above 7, typically about pH 9 or above, and generally require the presence of an alkalizing agent such as ammonia or an ammonia gas generating 1 91020977.1 Attorney Docket No.085137-765346 compounds and/or an amine or ammonium-based compounds in amounts sufficient to ensure alkalinity. The alkalizing agent causes the hair shaft to swell, thereby allowing small oxidative dye molecules to penetrate the cuticle and cortex before the oxidation condensation process is completed. The resulting, larger-sized color complexes from the oxidative reaction become trapped inside the hair fiber to permanently color the hair. While this process is effective for altering the color of the hair, these chemical treatments can damage the hair fibers leading to decreased strength of the hair, and negatively impact the sensorial properties of the hair, such as the smoothness, shine, and feel. Thus, to reduce or avoid these drawbacks, new components, compositions, and treatments are needed. The choice of such components, compositions, or treatments can pose difficulties insofar as they cannot be detrimental to other cosmetic attributes such as ease and uniformity of application, rheology or viscosity properties and stability of the compositions, color deposit and target shade formation, and/or result into more disadvantages such as increased damage or a less healthy look to the hair. It would therefore be desirable to provide the consumer with compositions and methods that can treat the hair, e.g. lift the color of hair and/or deposit color onto hair in an effective manner, while providing other cosmetic advantages such as shine, conditioning, fiber strength, and/or a healthy appearance to the hair, but avoiding or minimizing damage to the hair. Most types of hair coloring composition for permanently coloring hair are oxidative hair coloring compositions that use two parts. The first part is a hair coloring base composition that contains oxidative dye precursors (also called “oxidative dyes” or “oxidation dyes”) and couplers, which interact with the oxidative dye precursors. The second part is a developer composition containing an oxidizing agent like hydrogen peroxide. The two parts are mixed immediately prior to use forming a ready-to-use hair coloring composition (an “activated” coloring composition) that is applied to the hair for coloring the hair. Thus, ready- to-use hair coloring compositions can be called “active hair coloring compositions.” The oxidative dye precursors and oxidizing agents from the active hair coloring compositions diffuse into the hair shaft, where color formation takes place through a cascade of chemical reactions. The oxidative dye precursors are oxidized by the oxidizing agents and form reactive intermediates. Couplers, which are relatively stable to oxidizing agents, react with the intermediates resulting in vibrant coloring molecules. SUMMARY OF THE DISCLOSURE The hair coloring compositions of the instant disclosure include 2-methoxymethyl-P- phenylenediamine, an important oxidative dye precursor. Additional oxidative dye precursors, such as dimethylpiperazinium aminopyrazolopyridine and 2,3- diaminodihydropyrazolo pyrazolone dimethosulfonate, etc., may also optionally be included 2 91020977.1 Attorney Docket No.085137-765346 but are not required. The hair coloring base compositions of the instant disclosure are combined with a developer composition to generate a ready-to-use hair coloring composition. The ready-to-use hair coloring compositions of the instant disclosure typically have a relatively low pH (lower than normal ready-to-use coloring compositions), for example, in the range of below 10, below 9, or from about 6 to about 8. The hair coloring base compositions and specifically, the ready-to-use coloring compositions using the hair coloring base compositions, impart surprisingly long-lasting and vibrant colors to hair and unexpected toning and neutralizing effects to the hair. They are also gentle and non-irritating to the skin. They are useful for coloring all types of hair including hair of the head, eye lashes, eyebrows, and body, beard hair, and mustache hair. In addition to hair coloring base compositions and ready-to-use coloring compositions, the instant disclosure describes kits, methods for coloring or toning hair, and methods for making the hair coloring compositions. In a broad sense, the hair coloring base compositions include: - 2-methoxymethyl-P-phenylenediamine, and optionally one or more additional oxidative dye precursors; - one or more couplers; - less than 3 wt.%, preferably less than 2.5 wt.%, more preferably less than 2 wt.%, even more preferably less than 1.5 wt.% of one or more organic and/or mineral alkalizing agents, based on the total weight of the hair coloring base composition; - a plurality of surfactants in amounts higher than typically used in the art; - water and water-soluble organic solvents (which together can be referred to as simply “solvent”); and - optionally, one or more fatty alcohols. Unlike many hair coloring base compositions, the hair coloring base compositions of the instant disclosure lack high amounts of fatty compounds and do not have a large fatty phase. Fatty alcohols are considered a fatty compound and are preferably included in the hair coloring base compositions in may embodiments. Nonetheless, other than the fatty alcohols, the hair coloring base compositions typically include relatively minor amounts of fatty compounds.

The combination of (e), (f), and (g) are high due to unusually high amounts of surfactants in the compositions and the low amounts of fatty compounds. As mentioned above, the hair coloring base compositions include high amounts of one or more surfactants, preferably a plurality of surfactants. For example, the hair coloring base compositions preferably includes one or more nonionic surfactants, anionic surfactants, amphoteric surfactants, cationic surfactants, or a combination thereof. The total amount of the one or more surfactant (preferably, the plurality of surfactants) will vary but is typically from about 10 to about 40 wt.%, preferably about 15 to about 25 wt.%, more preferably about 18 to about 28 wt.%, based on the total weight of the hair coloring composition.

Betaines are particularly preferred. In a preferred embodiment, the hair coloring base composition includes: (a) 2-methoxymethyl-P-phenylenediamine, and optionally one or more additional oxidative dye precursors; (b) one or more couplers; (c) less than 3 wt.%, preferably less than 2.5 wt.%, more preferably less than 2 wt.%, even more preferably less than 1.5 wt.% of one or more organic and/or mineral alkalizing agents, based on the total weight of the hair coloring base composition; (d) optionally, one or more fatty alcohols, for example, fatty alcohols having from 12 to 24 carbon atoms; (e) about 5 to about 40 wt.% of a plurality of surfactants, wherein the total amount of the plurality of surfactants is preferably from about 10 to about 35 wt.%, more preferably from about 15 to about 30 wt.%, and even more preferably from about 18 to about 28 wt.%, wherein the plurality of surfactants preferably includes at least one nonionic surfactant and at least one anionic surfactant; (f) one or more water-soluble organic solvents; and (g) water; wherein (e), (f), and (g) are in amounts such that a combined amount of (e), (f), and (g) constitutes at least 70 wt.%, preferably at least 75 wt.%, and more preferably at least 80 wt.% of the hair coloring base composition; and all percentages by weight are based on the total weight of the hair coloring base composition. The pH of the hair coloring base compositions will vary but is typically from about 6 to about 10.5. The pH for the hair coloring base composition can influence the pH of the ready- to-use hair coloring composition formed by combining the hair coloring base composition with a developer composition. The pH of the ready-to-use hair coloring compositions (formed by combining the hair coloring base composition with a developer composition) will vary but is typically from about 6 to about 10.5. Alkalizing agents have multiple roles in the coloring process, in addition to providing alkalinity to influence pH.

Nonlimiting examples include cetyl alcohol, stearyl alcohol, cetearyl alcohol, behenyl alcohol, lauryl alcohol, myristic or myristyl alcohol, arachidyl alcohol, lignoceryl alcohol, and mixtures thereof. In other embodiments, however, fatty alcohols are not always needed or required and therefore, in certain embodiments, the hair coloring base composition is free or essentially free from the one or more fatty alcohols. The hair coloring base compositions typically include one or more reducing agents. Reducing agents are chemical species that lose an electron to another chemical species in a redox chemical reaction. Nonlimiting examples of reducing agents include ammonium bisulfite, ammonium sulfite, potassium metabisulfite, potassium sulfite, sodium hydrosulfite, sodium metabisulfite, sodium sulfite, sodium bisulphite, thioglycolic acid, thiolactic acid, dehydroascorbic acid, a salt thereof, and a mixture thereof. In certain embodiments, the hair coloring base compositions include thioglycolic acid, thiolactic acid, salts thereof, and mixtures thereof. A nonlimiting exemplary salt is ammonium thiolactate. In various embodiments, the hair coloring base compositions are free or essentially free from ammonia and/or ammonium ions and/or ammonium hydroxide. The hair coloring base compositions are mixed with developer compositions to form ready-to-use hair coloring compositions. The pH for the hair coloring base composition can influence the pH of the ready-to-use hair coloring composition formed by combining the hair 6 91020977.1 Attorney Docket No.085137-765346 coloring base composition with a developer composition. The hair coloring base composition may be mixed with a developer composition in a weight ratio of about 5:1 to about 1:5, about 3:1 to about 1:3, about 2:1 to about 1:2, or about 1:1. The pH of the hair coloring base composition will vary but is typically from about 6 to about 10.5. In further embodiments, the pH of the hair coloring base composition is from about 6.5 to about 10.5, about 7 to 10.5, about 7.5 to about 10.5, about 7.8 to about 10.5, about 6 to about 10, about 6.5 to about 10, about 7 to about 10, about 7.5 to about 10, or about 7.8 to about 10. The pH of the hair coloring base composition is preferably from about 6.5 to about 10.5, more preferably from about 7 to about 10, and even more preferably from about 7.8 to about 10. In a preferred embodiment, the pH of the hair coloring base composition is from about 7.5 to about 10, more preferably about 7.8 to about 10. The pH of the ready-to-use hair coloring compositions (formed by combining the hair coloring base composition with a developer composition) will vary but is typically from about 6 to about 10.5. In further embodiments, the pH of the ready-to-use hair coloring composition is from 6 to about 10, about 6 to about 9.5, about 6 to about 9, about 6 to about 8.5, about 6 to about 8, about 6 to about 7.8, about 6.1 o about 10, about 6.1 to about 9.5, about 6.1 to about 9, about 6.1 to about 8.5, about 6.1 to about 8, about 6.1 to about 7.8, about 6.5 to about 10, about 6.5 to about 9.5, about 6.5 to about 9, about 6.5 to about 8.5, about 6.5 to about 8, or about 6.5 to about 7.8. In a preferred embodiment, the ready-to-use hair coloring composition has a pH of about 6 to about 8, more preferably about 6.1 to about 7.8. The hair coloring base compositions and the developer compositions are separately contained prior to mixing. Thus, both compositions can be provided in a kit. Kits according to the instant disclosure include one or more hair coloring base compositions and one or more developer compositions, wherein the hair coloring base compositions and the developer compositions are separately contained. For example, the one or more hair coloring base compositions and the one or more developer compositions may be included in separate containers that are packaged together. Methods for making a ready-to-use hair coloring compositions and methods for coloring hair with the compositions entail combining the hair coloring base composition with a developer composition to form a ready-to-use hair coloring composition. The ready-to-use hair coloring composition is then applied to hair for a period of time (for processing), for example, for about 1 to about 30 minutes, about 1 to about 20 minutes, or about 1 to about 15 minutes, about 1 to 10 minutes, or amount 1 to 5 minutes. After the period of time has lapsed, the hair coloring compositions may be rinsed or washed from the hair exposing the 7 91020977.1 Attorney Docket No.085137-765346 newly colored hair. The newly colored hair durably retains its changed color, suffers little or no undesirable chemical damage, and the underlying skin is not subjected to burning and stinging associated with various oxidative coloring methods.

DETAILED DESCRIPTION OF THE DISCLOSURE The instant disclosure is drawn to hair coloring base compositions and to ready-to- use coloring compositions that include 2-methoxymethyl-P-phenylenediamine, an important oxidative dye precursor. Additional oxidative dye precursors, such as dimethylpiperazinium aminopyrazolopyridine and 2,3-diaminodihydropyrazolo pyrazolone dimethosulfonate, etc., may also optionally be included, but are not required. The hair coloring base composition is combined with a developer composition to derive a ready-to-use hair coloring composition having a relatively low pH, in the range of below 9, or from about 6 to about 8. These unique hair coloring compositions impart long-lasting color to hair. These unique hair coloring or toning compositions impart surprisingly long-lasting and vibrant colors to hair and 8 91020977.1 Attorney Docket No.085137-765346 unexpected toning and neutralizing effects to hair. They are also typically gentle and non- irritating to the skin. Different parts of the body grow different types of hair. “Lanugo hair” is the covering of fine hair which covers most newborn babies. It tends to fall out soon before or just after birth. “Vellus hair” is short, fine, and lightly colored. It develops over the body during childhood, except for the lips, palms, soles, back of the ears, in the navel, etc. These hairs sprout from follicles which are not connected to an oil gland. “Terminal hair grows primarily on the head. It is long, thick, and darker than hair elsewhere on the body. When a person enters puberty, terminal hair replaces vellus hair on the pubic area and in the armpits. Men in particular may also develop terminal hair in place of vellus hair on the chest, limbs, feet, back, and face. When it develops in puberty/adolescence, it is called androgenic hair. The hair on the scalp, like that on the face, grows in three steps, but the hair on the face has a much shorter growing phase. These steps include the active growth phase (anagen), the transitional phase (catagen- when growth stops) and the falling out phase (telogen). On the scalp, this cycle lasts for years; on the face it is a matter of months. Beard and mustache hair (androgenic hair) can be very different than hair grown on the scalp, or elsewhere on the body. Androgenic facial hair tends to be thicker with a wirier texture and can exhibit a different color than scalp hair. An individual may retain a full head of colored hair into middle age, yet the beard may grow partially or completely grey. Scalp hair may be straight, yet androgenic facial hairs grow thicker and curly due in part to the different shape of the follicles. Follicles on the face are much more sensitive to androgens like testosterone, which can cause follicles to twist and grow curly hair. The skin under androgenic facial hair is also different from skin of the scalp. The hair coloring base compositions and the ready-to- use coloring compositions of the instant case are useful for coloring all types of hair. Nonetheless, in preferred embodiments, the compositions are particularly useful for coloring the hair of the head, eye brows, facial hair (beard and/or mustache), or a combination thereof. The hair coloring base compositions of the instant disclosure typically include: (a) 2-methoxymethyl-P-phenylenediamine, and optionally one or more additional oxidative dye precursors; (b) one or more couplers; and (c) one or more alkalizing agents; (d) optionally, one or more fatty alcohols having from 12 to 24 carbon atoms; (e) about 10 to about 40 wt.% of one or more surfactants; 9 91020977.1 Attorney Docket No.085137-765346 (f) one or more water-soluble organic solvents; and (g) water; wherein (e), (f), and (g) are in amounts such that a combined amount of (e), (f), and (g) constitutes at least 70 wt.% of the hair coloring base composition, and all percentages by weight are based on a total weight of the hair coloring composition. In certain embodiments, the hair coloring base compositions of the instant disclosure include: (a) 2-methoxymethyl-P-phenylenediamine, and optionally one or more additional oxidative dye precursors; (b) one or more couplers; and (c) 3 wt.% or less of one or more alkalizing agents; (d) about 0.1 to about 15 wt.% of one or more fatty alcohols having from 12 to 24 carbon atoms; (e) about 5 to about 40 wt.%, preferably about 10 to about 40 wt.%, more preferably about 15 to about 30 wt.%, and even more preferably about 18 to about 28 wt.% of one or more surfactants, preferably a plurality of surfactants; (f) about 1 to about 40 wt.% of one or more water-soluble organic solvents; (g) water; wherein (e), (f), and (g) are in amounts such that a combined amount of (e), (f), and (g) constitutes at least 70 wt.% of the hair coloring base composition; the hair coloring base composition forms a ready-to-use hair coloring composition having a pH from about 6 to about 8 upon mixing with a developer composition comprising hydrogen peroxide in a weight ratio of about 1:5 to about 5:1 (hair coloring base composition : developer composition); and all percentages by weight are based on the total weight of the hair coloring base composition. In various embodiments, the hair coloring base compositions are free for essentially free from ammonia and/or ammonium ions and/or ammonium hydroxide. In various embodiments, the hair coloring base compositions are free or essentially free from resorcinol and/or resorcinol derivatives. The hair color altering compositions may, in some embodiments, be free or substantially free of para-phenylenediamines (other than 2- methoxymethyl-P-phenylenediamine), resorcinol, and/or resorcinol derivatives. In some 10 91020977.1 Attorney Docket No.085137-765346 embodiments, the hair color altering compositions may be free or substantially free of one or more of mineral oil, ammonia, ammonium hydroxide, ammonium thiolactate, para- phenylenediamines (other than 2-methoxymethyl-P-phenylenediamine), resorcinol, and/or resorcinol derivatives. In other embodiments, the hair color altering compositions may be free or substantially free of mineral oil, ammonia, ammonium hydroxide, ammonium thiolactate, para-phenylenediamines (other than 2-methoxymethyl-P-phenylenediamine), resorcinol, and resorcinol derivatives. For example, in various embodiments, the hair coloring base composition includes less than 0.1 wt.%, less than 0.05 wt.%, less than 0.01 wt.%, or less than 0.001 wt.% of resorcinol and/or resorcinol derivatives. The total amount of alkalizing agent (e.g., monoethanolamine) in the hair coloring base composition such that when mixed with a developer composition to form a ready-to-use hair coloring composition, the total amount of alkalizing agent in the ready-to-use coloring composition is less than 2 wt.%, preferably less than 1.5 wt.%, more preferably less than 1 wt.% In various embodiments, the hair coloring base compositions are such that they form a ready-to-use hair coloring composition having a desired pH upon mixing with a developer composition comprising hydrogen peroxide in a weight ratio about 5:1 to about 1:5, about 4:1 to about 1:4, about 3:1 to about 1:3, about 2:1 to about 1:2 or about 1:1 (hair coloring composition : developer composition). In certain embodiments, the desired pH is obtained when mixed in a 1:1 ratio with a developer consisting of: (a) about 7.5 wt.% hydrogen peroxide; (b) about 82 wt.% water; (c) about 0.5 wt.% glycerin; (d) about 2.3 wt.% of cetearyl alcohol; (e) about 0.9 wt.% of trideceth-2 carboxamide MEA; (f) about 0.6 wt.% ceteareth-25; and wherein all percentages by weight for components of the developer composition are based on the total weight of the developer composition. The developer composition described above is non-limiting and is provided simply as an example or standard to determine whether a hair coloring base composition results in a ready-to-use coloring composition having the claimed pH when mixed at the specified ratio.

Oxidative dye precursors are also referred to as “primary intermediates” or “oxidation bases.” Oxidative dye precursors are often colorless or weakly colored compounds, which, when combined with oxidizing products, reactive via oxidative condensation to provide colored species. The shades obtained with oxidative dye precursors may be varied by combining them with one or more couplers. The total amount of the 2-methoxymethyl-P-phenylenediamine in the hair coloring base composition will vary depending on the desired color and intensity of the hair to be treated. Nonetheless, in various embodiments, the total amount of the 2-methoxymethyl-P- phenylenediamine, is from about 0.001 to about 10 wt.%, about 0.001 to about 8 wt.%, about 0.001 to about 5 wt.%, about 0.001 to about 3 wt.%, about 0.01 to about 10 wt.%, about 0.01 to about 8 wt.%, about 0.01 to about 6 wt.%, or about 0.01 to about 5 wt.%, about 0.01 to about 3 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 8 wt.%, about 0.1 to about 6 wt.%, about 0.1 to about 5 wt.%, about 0.1 to about 3 wt.%, about 0.2 to about 10 wt.%, about 0.2 to about 8 wt.%, about 0.2 to about 6 wt.%, about 0.2 to about 5 wt.%, or about 0.2 to about 3 wt.%, based on the total weight of the hair coloring base composition.

By way of example only, the viscosity of the hair coloring base compositions may range from about 20 cps to about 150 cps, such as, for example, from about 20 to about 125 cps, about 20 to about 100 cps, about 20 to about 85 cps, about 20 to about 70 cps, about 25 to about 125 cps, about 25 to about 100 cps, about 25 to about 85 cps, about 25 to about 70 cps, about 30 to about 125 cps, about 30 to about 100 cps, about 30 to about 85 cps, about 30 to about 70 cps, about 50 to about 100 cps, about 60 to about 100 cps, about 70 to about 100 cps, about 50 to about 90 cps, about 50 to about 80 cps, or about 50 to about 75 cps, when measured at 25°C using a M3 spindle at 100 rpm, for example, using a Rheomat RM 180. In some non-limiting embodiments where the developer composition is liquid, e.g. aqueous, the developer composition may have a viscosity ranging from about 250 to about 2000 cps, such as, for example, from about 500 to about 2500 cps, about 500 to about 2000 76 91020977.1 Attorney Docket No.085137-765346 cps, about 500 to about 1500 cps, about 600 to about 1300 cps, or about 650 to about 1200 cps when measured at 25°C using a #4 spindle at 100 rpm, for example, using a Rheomat RM 180. By way of example, the viscosity of the ready-to-use hair coloring composition can range from about 250 cps to about 2500 cps, such as, for example, from about 250 to about 2000 cps, about 250 to about 1800 cps, about 250 to about 1600 cps, about 300 to about 2000 cps, about 300 to about 1800 cps, about 300 to about 1600 cps, about 350 to about 2000 cps, about 350 to about 1800 cps, about 350 to about 1600 cps, about 400 to about 2000 cps, about 400 to about 1800 cps, about 400 to about 1600 cps, about 450 to about 2000 cps, about 450 to about 1800 cps, about 450 to about 1600 cps, about 500 to about 2000 cps, about 500 to about 1800 cps, or about 500 to about 1600 cps, when measured at 25°C using a M3 spindle at 100 rpm, for example, using a Rheomat RM 180. Methods The compositions of the instant disclosure are useful in methods for making ready-to- use hair coloring compositions and for methods of coloring hair. Methods for making a ready-to-use hair coloring composition include combining one or more hair coloring base compositions according to the instant disclosure with one or more developer compositions, including one or more developer compositions of the instant disclosure. However, the methods are not limited to developer compositions of the instant disclosure. In various embodiments, a coloring base composition is combined with a developer composition to form a ready-to-use hair coloring composition. The one or more hair coloring base compositions can be combined with the one or more developer compositions in a weight ratio of about 1:5 to about 5:1 (hair coloring base composition: developer composition). In some cases, the weight ratio is about 1:4 to about 4:1, about 1:3 to about 3:1, about 1:2 to about 2:1, or about 1:1 (hair coloring base composition: developer composition). Methods for coloring hair include applying a ready-to-use hair coloring composition of the instant disclosure to the hair. The ready-to-use hair coloring composition may be prepared as described above, i.e., by combining one or more hair coloring base compositions according to the instant disclosure with one or more developer compositions. The ready-to-use hair coloring composition is typically used (applied to hair) shortly after formation, i.e. shortly after the hair coloring base composition is combined with the developer composition to form a ready-to-use hair coloring composition, the ready-to-use hair coloring composition is applied to hair. In various embodiments, the ready-to-use hair coloring composition is applied to hair within about 1 hour after formation. In further embodiments, the ready-to-use hair coloring composition is applied to the immediately after formation up to 77 91020977.1 Attorney Docket No.085137-765346 about 1 hour after formation, up to about 45 minutes after formation, up to about 30 minutes after formation, or up to about 15 minutes after formation. The ready-to-use hair coloring composition may be applied to hair of the head, hair of the body, facial hair (including beard hair and mustache hair), eyelashes, and/or eyebrows. In certain embodiments, the hair to be treated (colored) has been previously chemically treated, for example, previously bleached, previously colored, previously permed, previously straightened, etc. In further embodiments, the hair to be treated (colored) includes naturally grey hair, i.e., hair which has developed a loss of natural pigmentation and/or melanin. After application to hair, the ready-to-use hair coloring composition is allowed to remain on the hair for a period of time, for example, a period of time sufficient to achieve a desired change in the color of the hair. For example, the ready-to-use hair coloring composition may be allowed to remain on the hair for up to 1 hour, such as from about 1 minute to about 45 minutes, about 1 minute to about 30 minutes, about 1 minute to about 15 minutes, about 2 minutes to about 1 hour, about 2 minutes to about 45 minutes, about 2 minutes to about 30 minutes, about 2 minutes to about 15 minutes, about 2 minutes to about 10 minutes, about 3 minutes to about 30 minutes, about 3 minutes to about 25 minutes, about 3 minutes to about 20 minutes, about 3 minutes to about 15 minutes, about 3 minutes to about 10 minutes, or about 5 minutes to about 10 minutes. Those skilled in the art will, by considering various factors such as the starting and desired color of the hair, be able to determine an appropriate amount of time to leave the ready-to-use hair coloring composition on the hair to achieve the desired result. After the ready-to-use hair coloring composition is allowed to remain on the hair for a period of time, the ready-to-use hair coloring composition may, optionally be rinsed or cleansed (e.g., shampooed) from the hair. Forms The hair coloring compositions of the instant disclosure (hair coloring base compositions, developer compositions, and ready-to-use hair coloring compositions) can be in a variety of forms. For example, in many instances, the compositions are in the form of a liquid, gel, lotion, crème, and/or spray. The compositions may be packaged in a variety of different containers. Nonlimiting examples of useful packaging include tubes, jars, caps, unit dose packages, and bottles, including squeezable tubes and bottles. Kits The hair coloring base compositions of the instant disclosure may be present in a kit. For example, in certain embodiments, such kits include: (i) one or more hair coloring base compositions according to the instant disclosure; and (ii) one or more developer composition comprising one or more oxidizing agents; wherein the one or more hair coloring base 78 91020977.1 Attorney Docket No.085137-765346 compositions of (i) and the one or more developer compositions of (ii) are separately contained. In some embodiments, the developer composition is aqueous or is in the form of an emulsion. The developer composition can contain at least one solvent, chosen from water, organic solvents, and mixtures thereof. In various exemplary embodiments, hydrogen peroxide is present in an amount of at least about 1% by weight, based on the total weight of the developer composition. In further embodiments, hydrogen peroxide is present in an amount ranging from about 0.1% to about 80% by weight, such as from about 1.0% to about 75% by weight, or from about 2% to about 10% by weight, based on the total weight of the developer composition. In further exemplary embodiments, the hydrogen peroxide may be present in the developer composition in an amount ranging from about 2% to about 25%, such as about 4% to about 20%, about 6% to about 15%, or about 7% to about 10%. A cosmetically acceptable carrier for the developer composition may, for example, be present in an amount ranging from about 0.5% to about 99% by weight, such as from about 5% to about 95% by weight, relative to the total weight of the developer composition. In alternative embodiments, the developer composition is substantially anhydrous. The term “substantially anhydrous” means that the developer composition is either completely free of water or contains no appreciable amount of water, for example, no more than 5% by weight, or no more than 2% by weight, or no more than 1% by weight, based on the weight of the developer composition. It should be noted that this refers, for example, to bound water, such as the water of crystallization of the salts or traces of water absorbed by the raw materials used in the preparation of the compositions according to embodiments of the disclosure. When the developer composition is substantially anhydrous, the developer composition may comprise at least one solvent chosen from organic solvents. Suitable organic solvents for use in the developer composition include ethanol, isopropyl alcohol, propanol, benzyl alcohol, phenyl ethyl alcohol, glycols and glycol ethers, such as propylene glycol, hexylene glycol, ethylene glycol monomethyl, monoethyl or monobutyl ether, propylene glycol and its ethers, such as propylene glycol monomethyl ether, butylene glycol, dipropylene glycol, diethylene glycol alkyl ethers, such as diethylene glycol monoethyl ether and monobutyl ether, ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, propane diol, glycerin, hydrocarbons such as straight chain hydrocarbons, mineral oil, polybutene, hydrogenated polyisobutene, hydrogenated polydecene, polydecene, squalane, petrolatum , isoparaffins, and mixtures, thereof. 79 91020977.1 Attorney Docket No.085137-765346 The developer composition may be in the form of a powder, gel, liquid, foam, lotion, cream, mousse, and emulsion. The pH of the developer composition can range from about 2 to about 12, such as from about 3 to about 7, and it may be adjusted to the desired value using acidifying/ alkalizing agents that are well known in the art.

EXAMPLE 4 The color effects of the base dyes The hair coloring base compositions of Formulas 1 to 7 of Example 1 and the hair coloring base compositions of Formulas a to f of Example 2 were mixed with the developer composition of Example 3 (liquid) in a 1:1 ratio to form ready-to-use hair coloring compositions. The hair coloring base compositions are identical except for the base dyes and couplers. The mixtures were applied to sample swatches, which are commercially available. The mixtures were allowed to remain on the hair of the swatches (to process) for 20 minutes before being rinsed from the hair with water. Figure 1. showed that different color tones when different base dyes were used. The results clearly and surprisingly demonstrated that 2-Methoxymethyl-P-Phenylenediamine yielded more vibrant colors compared to other base dyes such as toluene-2,5-diamine (And) thioglycerin. 82 91020977.1 Attorney Docket No.085137-765346 EXAMPLE 5 Tenacity Study for 2-Methoxymethyl-P-Phenylenediamine The hair coloring base compositions Formulas 1 to 6 of Example 1 were mixed with the developer composition of Example 3 (liquid) in a 1:1 ratio to form ready-to-use hair coloring compositions. The hair coloring base compositions are identical except for the couplers. The mixtures were applied to sample swatches, which are commercially available. The mixtures were allowed to remain on the hair of the swatches (to process) for 20 minutes before being rinsed from the hair with water. The hair swatches were subsequently washed with a standard sulfate-base hair cleansing composition. The washing and drying procedure was repeated for many cycles, i.e., the hair swatches were washed with the standard sulfate-based hair cleansing composition and subsequently dried 28 consecutive times. Color images were captured of the swatches before application, after the initial treatment with the ready-to-use hair coloring compositions, as well as after 5, 10, and 15, 20, and 28 washes. As illustrated in Figure 2, all tested compositions exhibited good color retention after 28 washes. EXAMPLE 6 Comparative Tenacity Study for 2-Methoxymethyl-P-Phenylenediamine Vs. Toluene-2,5-Diamine (And) Thioglycerin The hair coloring base compositions of inventive Formulas 2 and 8, and comparative Formulas (g) and (h) in the table below were mixed with the developer composition of Example 3 (liquid) in a 1:1 ratio to form ready-to-use hair coloring compositions. The hair coloring base compositions are identical to the inventive formulas in Example 1 and comparative formulas in Example 2 except for the base dyes and couplers. In all four formulas, the base dye to coupler(s) molar ratio was about 1 to 1, and the dyes and couplers concentration were adjusted to obtain similar initial color deposition. 83 91020977.1 Attorney Docket No.085137-765346 Formulas Comparison F2 F8 F(g) F(h) OXIDATIVE 2-METHOXYMETHYL-P- 0^{4 04} ² 1 2 2,

The mixtures were allowed to remain on the hair of the swatches (to process) for 20 minutes before being rinsed from the hair with water. The hair swatches were subsequently washed with a standard sulfate-base hair cleansing composition. The washing and drying procedure was repeated for many cycles, i.e., the hair swatches were washed with the standard sulfate-based hair cleansing composition and subsequently dried 28 consecutive times. Color images and color changes of the swatches were captured before application, after the initial treatment with the ready-to-use hair coloring compositions, as well as after 5, 10, and 15, 20, and 28 washes. The color retention on the hair swatches was assessed as a function of washing using CIE L*a*b* coordinates. ΔE represents a difference in color, where a greater ΔE value represents increased removal of color or decreased retention of color. ΔE is defined by the following equation: ∆ ^^ = √( ^^^∗ − ^^^∗ ₀ )² + ( ^^^∗ − ^^₀ ^∗)² + ( ^^^∗ − ^^₀ ^∗)² where L*, a*, and b*

and L0*, a0*, and b0* represent values measured before treatment(s). As illustrated in Figure 3, the test compositions of inventive formulas exhibited provided significantly better color retention compared to the comparative formulas. 84 91020977.1 Attorney Docket No.085137-765346 EXAMPLE 7 Comparative Toning and Neutralizing Study for 2-Methoxymethyl-P-Phenylenediamine Vs.

The mixtures were allowed to remain on the hair of the swatches (to process) for 20 minutes before being rinsed from the hair with water. The hair swatches were subsequently washed with a standard sulfate-base hair cleansing composition. The washing and drying procedure was repeated for many cycles, i.e., the hair swatches were washed with the standard sulfate-based hair cleansing composition and subsequently dried 30 consecutive times. Color images, delta E and delta B values of the swatches were measured before application, after the initial treatment with the ready-to-use hair coloring compositions, as well as after 5, 10, and 15, 20, 25, and 30 washes. Delta B value represents color change from blueness to yellowness. i.e., Δb* = b* – b₀* as described in Example 6. The higher the delta B-Value, the higher the yellowness. Lower delta B value means more neutralizing 85 91020977.1 Attorney Docket No.085137-765346 As showed in Figure 4 and Figure 5, the test inventive formulas have both lower Delta B and delta E after 30 washes compared to the comparative formulas. 86 91020977.1 Attorney Docket No.085137-765346 EXAMPLE 8 (HAIR COLORING BASE COMPOSITIONS)

The hair coloring base compositions E, F, G of Example 8 are identical except for the amount of ethanolamine. The higher amounts of ethanolamine included in hair coloring base compositions F and G resulted in these compositions having a higher pH than the hair coloring base composition E. The three ready-to-use hair coloring compositions are summarized in the table below. Ready-to-Use Coloring Content pH 5³

Each of the three hair coloring compositions were mixed with International 20V Developer at a mix ratio of 1:1. This mixture was applied to 90% grey hair swatches, which are commercially available. The mixtures were allowed to remain on the hair of the swatches (to process) for 5 minutes before being rinsed from the hair with water. The hair swatches were subsequently washed with a standard sulfate-base hair cleansing composition. The washing and drying procedure was repeated for 15 cycles, i.e., the hair swatches were washed with the standard sulfate-based hair cleansing composition and subsequently dried 15 consecutive times. Color measurements were taken and images were captured of the swatches before application, after the initial treatment with the ready-to-use hair coloring compositions, as well as after 5, 10, and 15 washes. The color retention on the hair swatches was assessed as a function of washing using CIE L*a*b* coordinates. ΔE represents a difference in color, where a greater ΔE value represents increased removal of color or decreased retention of color. ΔE is defined by the following equation: ∆ ^^ = ^^^∗ − ² + ^^^∗ − ² + ^^^∗ − ² 91020977.1

Attorney Docket No.085137-765346 where L*, a*, and b* represent values measured after a treatment, and L0*, a0*, and b0* represent values measured before treatment(s). The color of the hair was analyzed before treatments with the ready-to-use hair coloring composition; immediately after the initial treatment with the ready-to-use hair coloring compositions; and after being washed 5, 10, and 15 times. The results are shown in Figure 6. As illustrated by the data, the ready-to-use hair coloring compositions #1 and #2, having a pH of 7.5 and 6.3 respectively (prepared using hair coloring base compositions E and F), provided significantly better color retention on grey hair than the ready-to-use hair coloring composition #3 having a higher pH of 10 (prepared using hair coloring base composition G). EXAMPLE 12 (Tenacity Study) The procedure describe above in Example 11 was repeated except that the three ready-to-use hair coloring compositions were applied to 90% permed hair swatches (which are commercially available) instead of 90% bleached hair. The results are shown in Figure 7. As illustrated by the data, the ready-to-use hair coloring compositions #1 and #2, having a pH of 7.5 and 6.3 respectively (prepared using hair coloring base compositions E and F), provided significantly better color retention on permed hair than the ready-to-use hair coloring composition #3 having a higher pH of 10 (prepared using hair coloring base composition G). Definitions The term “hair” as used herein includes hair of the head, beard hair, mustache hair, eyebrow hair, eyelashes, and body hair, unless otherwise specified. The term “beard hair” includes mustache hair, unless otherwise specified. As used herein, the terms “comprising,” “having,” and “including” are used in their open, non-limiting sense. A “hair coloring base composition” as used herein is a hair coloring composition containing one or more oxidative dye precursors and is mixed with a developer composition to form a ready-to-use hair coloring composition. A “hair coloring base composition” may also be referred to as a “hair coloring or toning base composition.” 91 91020977.1 Attorney Docket No.085137-765346 A “developer composition” as used herein is a composition containing one or more oxidizing agents, preferably a peroxide (hydrogen peroxide) and is missed with a hair coloring base composition to form a ready-to-use hair coloring composition. A “ready-to-use hair coloring composition” is an “active” composition that includes one or more oxidative dye precursors and one or more oxidizing agents; and is formed by combining a hair coloring base composition with a developer composition. A “composition colorant” is a compound that colors the composition but does not have an appreciable coloring effect on hair. In other words, the composition colorant is included to provide color to the composition, for example, for aesthetic appeal. It is not included to impart color to the hair. Styling gels, for example, can be found in a variety of different colors (e.g., light blue, light pink, etc.) yet application of the styling gel to the hair does not change the color of the hair. "Oil" is used herein to refer to an organic compound insoluble in water at normal temperature (25° C) and at atmospheric pressure (760 mmHg), i.e. it has a water solubility of less than 5% by weight, or less than 1 % by weight, or less than 0.1 % by weight. Oils have in their structure a chain of at least two siloxane groups or at least one hydrocarbon chain having at least 6 carbon atoms. Furthermore, oils are generally soluble in organic solvents in the same conditions of temperature and pressure, for example in chloroform, ethanol, benzene or decamethylcyclopentasiloxane. Furthermore, oils are liquid at ordinary temperature (25°C) and at atmospheric pressure (760 mmHg). The oils preferably do not contain any carboxylic acid functions, i.e. they do not contain any -COOH or -COO- groups. As described throughout the disclosure fatty alcohols are independent from fatty compounds and oils, i.e., even if a fatty alcohol is present in the compositions of the instant disclosure, the compositions may nonetheless be free or essentially free from fatty compounds of oils (because fatty alcohols are not included in the definition of fatty compounds and oils). The terms “a,” “an,” and “the” are understood to encompass the plural as well as the singular. Thus, the term “a mixture thereof” also relates to “mixtures thereof.” Throughout the disclosure, the term “a mixture thereof” is used, following a list of elements as shown in the following example where letters A-F represent the elements: “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture thereof.” The term, “a mixture thereof” does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.” 92 91020977.1 Attorney Docket No.085137-765346 Likewise, the term “a salt thereof” also relates to “salts thereof.” Thus, where the disclosure refers to “an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, and a mixture thereof,” it indicates that that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be include, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included. The expression “one or more” means “at least one” and thus includes individual components as well as mixtures/combinations. The term “plurality” means “more than one” or “two or more.” Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions may be modified in all instances by the term “about,” meaning within +/- 5% of the indicated number. Some of the various categories of components identified may overlap. In such cases where overlap may exist and the composition includes both components (or the composition includes more than two components that overlap), an overlapping compound does not represent more than one component. For example, a fatty acid may be considered both an emulsifier and a fatty compound. If a particular composition includes both an emulsifier and a fatty compound, a single fatty acid will serve as only the emulsifier or only the fatty compound (the single fatty acid does not serve as both the emulsifier and the fatty component). Mention of “fatty acid” and “emulsifier” is set forth as merely one example for purposes of communicating intent. The salts referred to throughout the disclosure may include salts having a counter-ion such as an alkali metal, alkaline earth metal, or ammonium counter-ion. This list of counter- ions, however, is non-limiting. All surfactants described herein include the salt form of the surfactant, to the extent a salt form exists, regardless of whether a salt is specifically denoted. The term “treat” (and its grammatical variations) as used herein refers to the application of the compositions of the present disclosure onto the surface of keratinous substrates such as hair. The term ‘treat” (and its grammatical variations) as used herein also refers to contacting keratinous substrates such as hair with the compositions of the present disclosure. As used herein, all ranges provided are meant to include every specific range within, and combination of sub ranges between, the given ranges. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as sub ranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. All 93 91020977.1 Attorney Docket No.085137-765346 ranges and values disclosed herein are inclusive and combinable. For examples, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value to derive a sub-range, etc. All components positively set forth throughout the instant disclosure may be negatively excluded from the claims, e.g., a claimed composition may be “free,” “essentially free” (or “substantially free”) of one or more components that are positively set forth in the instant disclosure. As an example, silicones can optionally be included in the compositions but preferably the compositions are free or essentially free from silicones. Silicones are synthetic polymers made up of repeating units of siloxane, elemental silicon and oxygen, combined with other elements, most often carbon and hydrogen. Thus, silicones are also called polysiloxanes. The term “substantially free” or “essentially free” as used herein means that there is less than about 5% by weight of a specific material added to a composition, based on the total weight of the compositions. Nonetheless, the compositions may include less than about 1 wt.%, less than about 0.5 wt.%, less than about 0.1 wt.%, less than 0.01 wt.%, or less than 0.001 wt.%, or none of the specified material. All of the components set forth herein may be optionally included or excluded from the compositions/method/kits. When excluded, the compositions/methods/kits may be free or essentially free of the component.
