Description

Title of the invention: Hair coloring compositions suitable for facial hair. SCOPE OF DISCLOSURE

[0001] This disclosure relates to basic hair coloring compositions and ready-to-use hair coloring compositions comprising 2-methoxymethyl-p-phenylenediamine, an oxidative dye precursor. Methods for preparing the compositions and methods for coloring hair, particularly beard and moustache hair, are also disclosed. SUMMARY

[0002] There are various types of hair coloring compositions for temporary, semi-permanent, or permanent hair coloring. Most types of hair coloring compositions 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 (sometimes called "oxidative dyes") and couplers, which interact with the oxidative dye precursors. The second part is a developer composition containing an oxidizing agent such as hydrogen peroxide. The two parts are mixed immediately before use, forming a ready-to-use hair coloring composition that activates the hair coloring composition.Thus, ready-to-use hair coloring compositions can be called "active hair coloring compositions." The oxidative dye precursors and oxidizing agents in active hair coloring compositions diffuse into the hair shaft, where color formation occurs through a cascade of chemical reactions. The oxidative dye precursors are oxidized by the oxidizing agents, forming reactive intermediates. The couplers, which are relatively stable with respect to the oxidizing agents, react with these intermediates, leading to vibrant color molecules.

[0003] The hair coloring compositions of the present case include 2-methoxymethyl-p-phenylenediamine, an important oxidative dye precursor. Additional oxidative dye precursors, such as dimethylpiperazinium aminopyrazolopyridine and 2,3-diaminodihydropyrazolopyrazolone dimethosulfonate, etc., may also be included. The base hair coloring composition is combined with a developer composition to obtain a ready-to-use hair coloring composition having an inha- Typically low, in the range of approximately 6 to 8. These unique hair coloring compositions provide long-lasting color to hair while being gentle and non-irritating to the skin. They are useful for coloring all types of hair, including head hair, eyelashes, eyebrows, and body hair, but are particularly useful for coloring facial hair (beard and mustache).

[0004] The basic compositions for hair coloring include:

[0005] - of 2-methoxymethyl-P-phenylenediamine, and optionally one or more additional oxidative dye precursors;

[0006] - less than 3% by weight, preferably less than 2.5% by weight, in a way more preferred less than 2% by weight, even more preferred less than 1.5% by weight of one or more organic and / or mineral alkalizing agents, based on the total weight of the basic hair coloring composition;

[0007] - a combination of surfactants, water-soluble organic solvents and water constituting at least 70% by weight, preferably at least 75% by weight, more preferably at least 80% by weight of the base composition for hair coloring, based on the total weight of the base composition for hair coloring.

[0008] The pH of base hair coloring compositions is typically from about 7 to about 10, preferably from about 7.5 to about 9.5, and more preferably from about 8 to less than 9.5. A lower pH for the base hair coloring composition is useful for influencing the pH of a ready-to-use hair coloring composition formed by combining the base hair coloring composition with a developer composition. The pH of ready-to-use hair coloring compositions formed with base hair coloring compositions is from about 6 to about 8, preferably from about 6.1 to about 7.9, and more preferably from about 6.2 to about 7.8, which is lower than that of most ready-to-use hair coloring compositions.

[0009] Alkalizing agents have multiple roles in the coloring process, in addition to providing alkalinity to influence pH. Non-limiting examples of organic alkalizing agents include monoethanolamine, diethanolamine, triethanolamine, monoisopropanolamine, diisopropanolamine, triisopropanolamine, N,N-dimethylethanolamine, 2-amino-2-methyl-l-propanol, 2-amino-2-methyl-l,3-propanediol, 3-amino-l,2-propanediol, 3-dimethylamino-l,2-propanediol, tris(hydroxymethyl)aminomethane, or mixtures thereof. Non-limiting examples of mineral alkalizing agents include ammonia, ammonium carbonates, sodium carbonates, potassium carbonates, ammonium bicarbonates, sodium bicarbonates, potassium bicarbonates, ammonium hydroxides, sodium hydroxides, potassium hydroxides, or mixtures thereof. However, in various embodiments, the basic hair coloring composition is free or essentially free of ammonia and / or ammonium ions, and / or ammonium hydroxide.

[0010] Surfactants may be nonionic, anionic, amphoteric (zwitterionic), or cationic. In various embodiments, the basic hair coloring compositions comprise one or more nonionic surfactants. In other embodiments, the basic hair coloring compositions comprise one or more nonionic surfactants and one or more anionic surfactants, for example, a fatty amide (nonionic surfactant) and a carboxylic ether (anionic surfactant).

[0011] The basic hair coloring compositions are aqueous. In addition to water, however, the hair coloring compositions may include one or more water-soluble organic solvents. Non-limiting examples of water-soluble organic solvents include glycerin, monoalcohols, polyols (polyhydric alcohols), glycols, and mixtures thereof, for example, glycerin, propylene glycol, butylene glycol, pentylene glycol, dipropylene glycol, hexylene glycol, ethanol, isopropanol, t-butyl alcohol, and mixtures thereof.

[0012] Additional components useful in basic hair coloring compositions include fatty alcohols, surfactants, and / or water-soluble organic solvents. In some embodiments, the fatty acids comprise from 12 to 24 carbon atoms. Non-limiting examples include cetyl alcohol, stearyl alcohol, cetearyl alcohol, behenyl alcohol, lauryl alcohol, myristic or myristyl alcohol, arachidyl alcohol, lignoceryl alcohol, and mixtures thereof.

[0013] In various embodiments, the basic hair coloring compositions include one or more reducing agents. Reducing agents are chemical species that lose an electron to another chemical species in a redox reaction. Non-limiting examples of reducing agents include ammonium bisulfite, ammonium sulfite, potassium metabisulfite, potassium sulfite, sodium hydrosulfite, sodium metabisulfite, sodium sulfite, sodium bisulfite, thioglycolic acid, thiolactic acid, dehydroascorbic acid, salts thereof, and mixtures thereof. In some embodiments, the basic hair coloring compositions include thioglycolic acid, thiolactic acid, salts thereof, and mixtures thereof.

[0014] In addition to the preceding, in various embodiments, the basic hair coloring composition includes:

[0015] (a) of 2-methoxymethyl-P-phenylenediamine, and optionally one or more additional oxidative dye precursors;

[0016] (b) one or more couplers;

[0017] (c) less than 3% by weight, preferably less than 2.5% by weight, in a way more preferably less than 2% by weight, even more preferably less than 1.5% by weight of one or more organic and / or mineral alkalizing agents, on the basis of the total weight of the basic hair coloring composition0;

[0018] (d) one or more fatty alcohols;

[0019] (e) one or more surfactants;

[0020] (f) optionally one or more water-soluble organic solvents;

[0021] (g) of water.

[0022] wherein (e), (f) and (g) are in quantities such that a combined quantity of (e), (f) and (g) constitutes at least 70% by weight, preferably at least 75% by weight, more preferably at least 80% by weight of the basic hair coloring composition; and

[0023] All percentages by weight are based on the total weight of the base composition for hair coloring.

[0024] In various embodiments, the basic hair coloring compositions are free or essentially free of ammonia and / or ammonium ions and / or ammonium hydroxide.

[0025] The base compositions for hair coloring are mixed with developer compositions to form ready-to-use hair coloring compositions having a pH of about 6 to about 8, preferably about 6.1 to about 7.9, or more preferably about 6.2 to about 7.8. For example, the base compositions for hair coloring can 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, or about 2:1 to about 1:2. The pH of the base compositions for hair coloring is typically about 7 to about 10, preferably about 7.5 to about 9.5, more preferably about 8 to less than 9.5.A lower pH for the base hair coloring composition is useful for influencing the pH of a ready-to-use hair coloring composition formed by combining the base hair coloring composition with a developer composition.

[0026] The hair coloring base compositions and the developer compositions are contained separately before mixing. Thus, the two compositions can be supplied in a kit. The kits according to this disclosure include one or more hair coloring base compositions and one or more developer compositions, in which the hair coloring base compositions and the developer compositions are contained separately. For example, the one or Several base compositions of hair coloring and one or more developer compositions may be included in separate containers which are packaged together.

[0027] The methods for preparing ready-to-use hair coloring compositions and the methods for coloring hair with these compositions involve combining the base hair coloring 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 the hair for a period of time (for the treatment), for example, from approximately 1 to approximately 30 minutes, from approximately 1 to approximately 20 minutes, or from approximately 1 to approximately 15 minutes, from approximately 1 to 10 minutes, or from approximately 1 to 5 minutes. After the time period has elapsed, the hair coloring compositions can be removed from the hair by rinsing or washing, exposing the newly colored hair.The newly colored hairs retain their changed color permanently, suffer little or no unwanted chemical damage, and the underlying skin is not subjected to the burning and stinging associated with various oxidative coloring processes. Brief description of the designs.

[0028] Implementations of this technology will now be described, by way of example, with reference to the accompanying figures, in which:

[0029] [Fig-1] Fig. 1 is a graph showing the retention of gray hair color at 90% treated with a composition of the invention compared to hairs treated with two comparative compositions; and

[0030] [Fig.2] Fig.2 is a graph showing the color retention of hairs per- 90% of hairs treated with a composition of the invention compared to hairs treated with two comparative compositions.

[0031] The figures and the data they represent are not exhaustive and are provided simply to illustrate certain aspects of the technology. DETAILED DESCRIPTION

[0032] People often seek to permanently change the color of their hair using oxidative dyeing procedures. Complaints frequently associated with these procedures include the deposition of inadequate colors, damage to the hair and / or underlying skin, and hair discoloration over time. During the dyeing process, the hair coloring compositions often come into contact with the underlying skin. This can temporarily discolor the underlying skin, cause discomfort, and even, in some cases, damage the skin. Over time, the initial color imparted to the hair may fade. As the color fades, the hair may appear less vibrant, exhibit undesirable shades and appear neglected.

[0033] The hair coloring compositions and processes described in this case address the concerns raised above. They are gentle on the hair and the underlying skin while providing a fast, strong, and long-lasting color deposit. The hair coloring compositions are suitable for all hair types. However, due to their robust coloring ability and gentle nature, they are particularly well-suited for coloring facial hair (e.g., beard and mustache), which tends to be thicker than other hair.

[0034] Different types of hair grow on different parts of the body. Lanugo is the layer of fine down that covers most newborns. It tends to fall out soon after or just after birth. Down is short, fine, and slightly colored. It develops on the body during childhood, except for the lips, palms of the hands, soles of the feet, behind the ears, inside the navel, etc. This hair comes from follicles that are not connected to an oil gland. Terminal hairs grow mainly on the head. They are long, thick, and darker than the hair elsewhere on the body. When a person enters puberty, terminal hairs replace down in the pubic area and underarms. Males, in particular, may also develop terminal hairs instead of down on the chest, limbs, feet, back, and face.When they develop during puberty / adolescence, they are called androgenic hairs.

[0035] Scalp hair, like facial hair, grows in three stages, but facial hair has a much shorter growth phase. These stages include the active growth phase (anagen), the transitional phase (catagen, when growth stops), and the shedding 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 from the hair that grew on the scalp, or from hair elsewhere on the body. Androgenic facial hair tends to be thicker and coarser in texture and may be a different color than scalp hair. A person may retain fully colored hair well into middle age, while the beard may turn partially or completely gray.Scalp hair can be straight; however, facial androgenic hair is thicker and curlier, partly due to the different shape of the follicles. Facial follicles are much more sensitive to androgens such as testosterone, which can cause them to twist and result in curly hair growth. The skin beneath facial androgenic hair is also different from the skin on the scalp.

[0036] As noted previously, hair coloring compositions intended to permanently alter hair color typically consist of a combination of two parts: a hair coloring base composition and a developer composition. The hair coloring base composition includes oxidative dye precursors, such as 2-methoxymethyl-p-phenylenediamine, and the developer composition includes oxidizing agents, such as hydrogen peroxide. The two parts are mixed to form a ready-to-use hair coloring composition.

[0037] Oxidative dye precursors are typically colorless or faintly colored compounds which, when combined with oxidizing agents, are converted into colored species via an oxidative condensation process. The shades obtained with oxidative dye precursors can be varied by combining them with one or more couplers. Couplers include, for example, aromatic meta-diamines, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds, such as indole compounds.

[0038] The oxidizing agent(s) used in permanent hair dye compositions may degrade the melanin in the hair, which, depending on the nature of the oxidizing agent, may lead to less pronounced lightening of the fibers. A common oxidizing agent used in hair lightening and coloring is hydrogen peroxide. However, peroxygenated salts, such as persulfates, may be used, often in conjunction with hydrogen peroxide.

[0039] In general, hair coloring compositions are alkaline, having a high pH of approximately 9 and above, and may typically require the presence of an alkalizing agent such as ammonia or an ammonia-generating compound and / or an amine- or ammonium-based compound in sufficient quantities to achieve the desired alkalinity. The alkalizing agents help activate the oxidizing agents and cause the hair shaft to swell, allowing the small precursor molecules of oxidative dye to penetrate the cuticle and cortex before the completion of the oxidation condensation process. The larger color complexes resulting from the oxidative reaction are then trapped within the hair fiber, permanently altering the hair color.

[0040] In various embodiments, the basic hair coloring compositions of this disclosure include:

[0041] (a) of 2-methoxymethyl-P-phenylenediamine, and optionally one or more additional oxidative dye precursors;

[0042] (b) one or more couplers;

[0043] (c) less than 3% by weight, preferably less than 2.5% by weight, in a way more preferred less than 2% by weight, even more preferred less than 1.5% by weight of one or more organic and / or mineral alkalizing agents, based on the total weight of the base hair coloring composition0;

[0044] (d) about 0.1 to about 10% by weight of one or more fatty alcohols, for example, fatty alcohols containing 12 to 24 carbon atoms;

[0045] (e) approximately 15 to approximately 40% by weight of one or more surfactants;

[0046] (f) approximately 10 to approximately 40% by weight of one or more soluble organic solvents in the water;

[0047] (g) approximately 25 to approximately 60% by weight of water;

[0048] wherein (e), (f) and (g) are in quantities such that a combined quantity of (e), (f) and (g) constitutes at least 70% by weight of the basic hair coloring composition; and

[0049] All percentages by weight are based on the total weight of the base composition for hair coloring.

[0050] In various embodiments, the basic hair coloring compositions are free or essentially free of ammonia and / or ammonium ions, and / or ammonium hydroxide.

[0051] The pH of the hair coloring base composition will vary. However, the pH is typically such that when mixed with a developer composition to form a ready-to-use hair coloring composition, the ready-to-use hair coloring composition has a desired pH, for example, a pH of about 6 to about 8, preferably about 6.1 to about 7.9, more preferably about 6.2 to about 7.8. Developer compositions are typically acidic, for example, having a pH of 2 to about 6. Consequently, to obtain a ready-to-use hair coloring composition by mixing the developer composition with the hair coloring base composition, the hair coloring base composition must have a low pH, for example, about 7 to about 10, preferably about 7.5 to about 9.5, more preferably about 8 to less than 9.5.The pH of the hair coloring base composition, the pH of the developer composition, and the mixing ratio of the hair coloring base composition to the developer composition can influence the final pH of the ready-to-use hair coloring composition.

[0052] In various embodiments, the pH of the base composition for hair coloring is from about 7 to about 10, from about 7.5 to about 10, from about 8 to about 10, from about 8.5 to about 10, from about 7 to about 9.5, from about 7.5 to about 9.5, from about 8 to about 9.5, from about 8.5 to about 9.5, from about 7 to about 9, from about 7.5 to about 9, or from about 8 to about 9.

[0053] In various embodiments, the basic hair coloring compositions are free or essentially free of resorcinol and / or re- derivatives Sorcinol. Hair color modification compositions may, in certain embodiments, be free or substantially free of para-phenylenediamines (other than 2-methoxymethyl-p-phenylenediamine), resorcinol, and / or resorcinol derivatives. In certain embodiments, hair color modification compositions may be free or substantially free of one or more of the following: 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 modification 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 / or resorcinol derivatives.

[0054] As noted, the base hair coloring compositions of this disclosure can be combined with a developer composition to form a ready-to-use hair coloring composition having a pH of about 6 to about 8, preferably about 6.1 to about 7.9, or more preferably about 6.2 to about 7.8. The final pH of a ready-to-use hair coloring composition will depend on the content, pH, etc., of the base hair coloring composition.In various embodiments, the basic hair coloring compositions of this disclosure are such that they form a ready-to-use hair coloring composition having a pH of about 6 to about 8, about 6.1 to about 7.9, or about 6.2 to about 7.8, when mixed with a developer composition comprising hydrogen peroxide in a weight ratio of about 1:5 to about 5:1 (hair coloring composition developer composition).

[0055] Furthermore, the total amount of alkali-suppressing agent (e.g., monoethanolamine) in the base hair coloring composition is such that when mixed with a developer composition to form a ready-to-use hair coloring composition, the total amount of alkali-suppressing agent in the ready-to-use coloring composition is less than 2% by weight, preferably less than 1.5% by weight, more preferably less than 1% by weight.

[0056] For example, the hair coloring base compositions are such that they form a ready-to-use hair coloring composition having a pH of approximately 6 to approximately 8, approximately 6.1 to approximately 7.9, or approximately 6.2 to approximately 7.8, when mixed with a developer composition comprising hydrogen peroxide in a weight ratio of approximately 1:1 (hair coloring composition + developer composition), wherein the developer composition consists of:

[0057] (a) approximately 7.5% by weight of hydrogen peroxide;

[0058] (b) approximately 82% by weight of water;

[0059] (c) approximately 0.5% by weight of glycerin;

[0060] (d) approximately 2.3% by weight of cetearyl alcohol;

[0061] (e) approximately 0.9% by weight of trideceth-2 carboxamide MEA;

[0062] (f) approximately 0.6% by weight of ceteareth-25; and

[0063] in which all weight percentages for the components of the developer composition are based on the total weight of the developer composition.

[0064] The basic hair dye compositions include 2-methoxymethyl-p-phenylenediamine, which is an oxidative dye precursor, and optionally one or more additional oxidative dye precursors. Oxidative dye precursors are also called "primary intermediates" or "oxidation bases." Oxidative dye precursors are often colorless or weakly colored compounds, which, when combined with oxidizing agents, react via oxidative condensation to yield colored species.Non-limiting examples of oxidative dye precursors include aromatic diamines, polyhydric phenols, aminophenols, and derivatives of these compounds, such as, for example, N-substituted derivatives of amines, and phenol ethers, ortho- or para-aminophenols, ortho- or para-phenylenediamines, double bases, heterocyclic bases, and acid addition salts thereof. More specific non-limiting examples include dimethylpiperazinium aminopyrazolopyridine, 2,3-diaminodihydropyrazolopyrazolone dimethosulfonate, p-phenylenediamine, 2,5-diaminotoluene, N,N-bis(2-hydroxymethyl)-p-phenylenediamine, paminophenol, salts thereof, etc.

[0065] In some embodiments, in addition to 2-methoxymethyl-P-phenylenediamine, the basic hair coloring composition includes one or more oxidative dye precursors selected from dimethylpiperazinium aminopyrazolopyridine, 2,3-diaminodihydropyrazolopyrazolone dimethosulfonate, salts thereof, and combinations thereof.

[0066] A more exhaustive but not exhaustive list of useful oxidative dye precursors is described later, under the heading "Oxidative Dye Precursors".

[0067] The total amount of one or more oxidative dye precursors, including 2-methoxymethyl-p-phenylenediamine, will vary depending on the desired color and intensity of the hair to be treated.

[0069] The colors obtained using oxidative dye precursors can be modified by combining them with one or more couplers. Thus, in some embodiments, the base hair dye compositions of this disclosure include one or more couplers. Non-limiting examples of couplers include aromatic meta-diamines, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds, such as indole compounds. A more comprehensive but non-limiting list of couplers that can be included in the base hair dye compositions is provided later under the heading "Couplers." The variety of molecules used as oxidative dye precursors and couplers makes it possible to obtain a wide range of colors.

[0070] The total quantity of couplers, if any, will vary depending on the desired color of the hair to be treated. In various embodiments, the base hair coloring composition includes approximately 0.0001 to approximately 12% by weight, based on the total weight of the base hair coloring composition. In some cases, the total quantity of one or more couplers is approximately 0.001 to approximately 12% by weight, approximately 0.001 to approximately 10% by weight, approximately 0.001 to approximately 5% by weight, approximately 0.001 to approximately 3% by weight, approximately 0.01 to approximately 10% by weight, approximately 0.01 to approximately 8% by weight, approximately 0.01 to approximately 5% by weight, or approximately 0.01 to approximately 3% by weight, approximately 0.1 to approximately 10% by weight. weight, from about 0.1 to about 8% by weight, from about 0.1 to about 5% by weight, from about 0.1 to about 4% by weight, or from about 0.1 to about 3% by weight, based on the total weight of the base composition for hair coloring.

[0071] The weight ratio of the total amount of oxidative dye precursors (including 2-methoxymethyl-P-phenylenediamine) to the total amount of one or more couplers in the basic hair dye composition can be from about 1:1 to about 5:1, from about 1:1 to about 4:1, or from about 1:1 to about 3:1, from about 1:1 to about 2:1, or from about 1:1 to about 1.5:1.

The total quantity of one or more direct dyes, pigments, and / or mixtures thereof, as applicable, will vary. However, in certain embodiments, the total quantity of one or more direct dyes, pigments, and / or mixtures thereof, as appropriate, is approximately 0.01 to approximately 5% by weight, approximately 0.01 to approximately 3% by weight, approximately 0.01 to approximately 2% by weight, approximately 0.1 to approximately 5% by weight, approximately 0.1 to approximately 3% by weight, approximately 0.1 to approximately 2% by weight, or approximately 0.1 to approximately 1% by weight, based on the total weight of the basic hair coloring composition.

[0073] Alkalinizing agents in the hair coloring base composition typically play multiple roles in the coloring process. For example, the alkalinizing agent(s) are useful for achieving a desired pH. In addition, the alkalinizing agent(s) help to cause swelling of the hair shaft, allowing small molecules of the oxidative dye precursor to penetrate the cuticle and cortex more easily. Furthermore, the alkalinizing agents can activate one or more oxidizing agents in the developer composition and contribute to the oxidative condensation process.Non-limiting examples of alkalizing agents include ammonia, ammonium hydroxide, ammonium carbonate, ammonium chloride, ammonium sulfate, ammonium nitrate, ammonium phosphate, ammonium acetate, ammonium hydrogen carbonate, ammonium carbamate, percarbonate salts, alkanolamines (such as monoethanolamine, diethanolamine, triethanolamine, monopropanolamine, dipropanolamine, tripropanolamine, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-methyl-1,3-propanol, and 2-amino-2-hydroxymethyl-1,3-propanediol), guanidium salts, alkali metal hydroxides (such as sodium hydroxide), and alkali metal carbonates, and mixtures thereof.

[0074] The basic hair coloring compositions according to this disclosure may include one or more alkalizing agents. According to various methods of preparation lisation, the alkalizing agent may include at least one organic alkalizing agent and / or at least one mineral alkalizing agent.

In some embodiments, the alkali-forming component comprises ammonia and / or ammonium hydroxide.

[0077] In some embodiments, the alkali-forming agent comprises at least one organic alkali-forming agent and is free or substantially free of mineral alkali-forming agents. For example, the alkali-forming agent may comprise less than about 0.5%, less than about 0.4%, less than about 0.3%, less than about 0.2%, less than about 0.1%, or less than about 0.05% of mineral alkali-forming agents. In some embodiments, the alkali-forming agent comprises at least one organic alkali-forming agent and is free or substantially free of ammonia and / or ammonium ions and / or ammonium compounds. In various embodiments, the alkali-forming agent comprises monoethanolamine. In other embodiments, the alkali-forming agent comprises monoethanolamine and is free or substantially free of ammonia and / or ammonium ions and / or ammonium compounds.An "ammonium compound" in the context of this disclosure is a compound that produces ammonia when present in the composition at a particular pH.

Processes

[0366] The compositions of this disclosure are useful in processes for preparing ready-to-use hair coloring compositions and in hair coloring processes. Processes for preparing ready-to-use hair coloring compositions include combining one or more hair coloring base compositions according to this disclosure with one or more developer compositions, including one or more developer compositions of this disclosure. However, the processes are not limited to the developer compositions of this disclosure. In various embodiments, a coloring base composition is combined with a developer composition to form a ready-to-use hair coloring composition having a pH of about 6 to about 8, preferably about 6.1 to about 7.9, or more preferably about 6.2 to about 7.8.One or more hair coloring base compositions can be combined with one or more developer compositions in a ratio of approximately 1:5 to approximately 5:1 (hair coloring base composition to developer composition). In some cases, the weight ratio is approximately 1:4 to approximately 4:1, approximately 1:3 to approximately 3:1, approximately 1:2 to approximately 2:1, or approximately 1:1 (hair coloring base composition to developer composition), provided that the pH of the ready-to-use hair coloring composition is at the desired pH.

[0367] Hair coloring processes, particularly for facial hair (beard and / or mustache), include the application of a ready-to-use hair coloring composition of this disclosure to the hair. The ready-to-use hair coloring composition can be prepared as described above, namely, by combining one or more hair coloring base compositions according to this disclosure with one or more developer compositions. The ready-to-use hair coloring composition is typically used (applied to the hair) shortly after formation, that is, shortly after the hair coloring base composition has been combined with the developer composition to form a ready-to-use hair coloring composition, the ready-to-use hair coloring composition is applied to the hair.In various embodiments, the ready-to-use hair coloring composition is applied to the hair within 1 hour of training. In other embodiments, the ready-to-use hair coloring composition is applied immediately after training up to approximately 1 hour after training, or up to approximately 45 minutes after. training, up to about 30 minutes after the training or up to about 15 minutes after the training.

[0368] The ready-to-use hair coloring composition can be applied to the hair on the head, body hair, facial hair (including beard and mustache hair), eyelashes, and / or eyebrows. In some embodiments, the ready-to-use hair coloring composition is applied to facial hair, preferably beard and mustache hair. In some embodiments, the hair to be treated (colored) has been previously chemically treated, for example, bleached, previously colored, previously permed, previously straightened, etc. In other embodiments, the hair to be treated (colored) includes naturally gray hair, i.e., hair that has developed a loss of natural pigmentation and / or melanin.

[0369] After application to the hair, the ready-to-use hair coloring composition is left to rest on the hair for a period of time, for example, a period of time sufficient to achieve a desired change in hair color.For example, the ready-to-use hair coloring composition can be left to rest on the hair for a period of time of up to 1 hour, such as from about 1 minute to about 45 minutes, from about 1 minute to about 30 minutes, from about 1 minute to about 15 minutes, from about 2 minutes to about 1 hour, from about 2 minutes to about 45 minutes, from about 2 minutes to about 30 minutes, from about 2 minutes to about 15 minutes, from about 2 minutes to about 10 minutes, from about 3 minutes to about 30 minutes, from about 3 minutes to about 25 minutes, from about 3 minutes to about 20 minutes, from about 3 minutes to about 15 minutes, from about 3 minutes to about 10 minutes, or from about 5 minutes to about 10 minutes.A person skilled in the art, considering various factors such as the initial and desired hair color, will be able to determine an appropriate duration for leaving the ready-to-use hair coloring composition on the hair to achieve the desired result. After the ready-to-use hair coloring composition has been left on the hair for a period of time, it can optionally be removed from the hair by rinsing or washing (for example, shampooing). Shapes

[0382] The hair coloring bases E, F, and G of Example 1 were mixed with the developer composition of Example 2 in a 1:1 ratio to form ready-to-use hair coloring compositions. The hair coloring bases E, F, and G of Example 1 are identical except for the amount of ethanolamine. The higher amounts of ethanolamine included in the hair coloring bases F and G resulted in these compositions having a higher pH than the hair coloring base E. The three ready-to-use hair coloring compositions are summarized in the table below.

[0384] Each of the three hair dye compositions was mixed with International 20 V developer in a 1:1 mixing ratio. This mixture was applied The mixtures were applied to commercially available, 90% gray hair strands. They were left to sit on the hair (to be treated) for 5 minutes before being rinsed with water. The hair strands were then washed with a standard sulfate-based hair cleansing solution. This washing and rinsing procedure was repeated 15 times; that is, the hair strands were washed with the standard sulfate-based hair cleansing solution and then dried 15 consecutive times. Color measurements were taken, and images of the strands were captured before application, after the initial treatment with the ready-to-use hair coloring solutions, and after 5, 10, and 15 washes.

[0385] Color retention on the hair strands was evaluated as a function of washing using the CIE coordinates L*a*b*. AE represents a color difference, where a higher AE value represents increased color fading or reduced color retention. AE is defined by the following equation:

[0387] where L*, a* and b* represent the values ​​measured after a treatment, and LO*, aO* and bO* represent the values ​​measured before a treatment(s).

[0388] Hair color was analyzed before treatment 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 [Fig. 1].

[0389] 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 the basic hair coloring compositions E and F), provided substantially better color retention on grey hair than the ready-to-use hair coloring composition #3 having a higher pH of 10 (prepared using the basic hair coloring composition G). EXAMPLE 4 (Tenacity study)

[0390] The procedure described above in Example 3 was repeated, except that the three ready-to-use colour compositions were applied to 90% permed hair strands (which are commercially available) instead of 90% bleached hair. The results are shown in [Fig. 2].

[0391] As illustrated by the data, the ready-to-use hair coloring compositions #1 and #2, having pH values ​​of 7.5 and 6.3 respectively (prepared using the base hair coloring compositions E and F), provided substantially better color retention on permed hair than the composition of co ready-to-use hair coloring #3 having a higher pH of 10 (prepared using the basic hair coloring composition G). Definitions

[0392] The term “hair” as used herein includes head hair, beard hair, moustache hair, eyebrows, eyelashes, and body hair, unless otherwise specified.

[0393] The term “beard hair” includes moustache hair, unless otherwise specified.

[0394] As used herein, the terms “comprising”, “having” and “including” are understood in their open, non-limiting sense.

[0395] 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.

[0396] A "developer composition" as used herein is a composition containing one or more oxidizing agents, preferably a peroxide (hydrogen peroxide), and is mixed with a base hair coloring composition to form a ready-to-use hair coloring composition.

[0397] 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.

[0398] A "composition colorant" is a compound that colors the composition but has no appreciable coloring effect on the hair. In other words, the composition colorant is included to give color to the composition, for example, for aesthetic purposes. It is not included to give color to the hair. Hair gels, for example, may come in a variety of different colors (e.g., light blue, light pink, etc.), but applying the hair gel to the hair does not change the hair color.

[0399] The term "oil" is used here to refer to an organic compound that is insoluble in water at room temperature (25 °C) and atmospheric pressure (760 mmHg), namely, it has a water solubility of less than 5% by weight, or less than 1% by weight, or less than 0.1% by weight. The oils have in their structure a chain of at least two siloxane groups or at least one hydrocarbon chain comprising at least six carbon atoms. Furthermore, the oils are generally soluble in organic solvents under the same conditions of temperature and pressure, for example, in chloroform, ethanol, benzene, or decamethylcyclopentasiloxane. In addition, the oils are liquid at room temperature (25 °C) and atmospheric pressure (760 mmHg). The oils preferably do not contain carboxylic acid groups, namely, they do not contain -COOH or -COO- groups. As described throughout the disclosure, fatty alcohols are independent of fatty compounds and oils, i.e., even if a fatty alcohol is present in the compositions of this disclosure, the compositions may nevertheless be free or substantially free of fatty compounds of oils (since fatty alcohols are not included in the definition of fatty compounds and oils).

[0400] Throughout the disclosure, the phrase "a mixture of these" is used, following a list of items as shown in the following example where the letters A through F represent the items: "one or more items selected from the group consisting of A, B, C, D, E, F, and a mixture of these." The phrase "a mixture of these" 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 two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the wording "one or more items selected from the group consisting of A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E, and F."

[0401] Similarly, the expression "a salt of it" also refers to "salts of it." Thus, when the disclosure refers to "a selected element from the group consisting of A, B, C, D, E, F, a salt of these, or a mixture of these," it indicates 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 included, 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.

[0402] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations.

[0403] Some of the various identified component categories may overlap. In cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping component 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 only as an emulsifier or only as a fatty compound (the single fatty acid does not serve as both an emulsifier and a fatty compound).

[0404] The salts referred to throughout the disclosure may include salts containing a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions is not exhaustive.

[0405] The term "treat" (and its grammatical variations) is used here to do This refers to the application of the compositions of this disclosure to the surface of keratinous substrates such as hair. The term "treat" (and its grammatical variations) is also used here to refer to bringing keratinous substrates such as hair into contact with the compositions of this disclosure.

[0406] In this document, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of intermediate subranges. Thus, a range from 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. All ranges and values ​​disclosed herein are inclusive and combinable. For example, any value or point described in this document that falls within a range described in this document can serve as a minimum or maximum value to derive a subrange, etc.

[0407] The expression "substantially free" or "essentially free" as used in this document means that less than about 2% by weight of a specific material is added to a composition, relative to the total weight of the compositions. However, the compositions may include less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or none of the specified material. All components shown in this document may optionally be included or excluded from the compositions / processes / requirements. When excluded, the compositions / processes / requirements may be free or essentially free of the component. For example, a particular composition may be free or essentially free of alkoxylated compounds, e.g., ethoxylated thickeners and / or ethoxylated surfactants.Similarly, a particular composition may be free or essentially free of sulfates, such as sulfate surfactants.
