Description

Hair coloring compositions suitable for facial hair FIELD OF DISCLOSURE

The present disclosure relates to base 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 mustache hair, are also disclosed.

SUMMARY

There are different 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 basic hair coloring 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 to activate the hair coloring composition. Thus, ready-to-use hair coloring compositions may be called "active hair coloring compositions". The oxidative dye precursors and oxidizing agents of the active hair coloring compositions diffuse into the hair shaft, where color formation occurs through a cascade of chemical reactions. Oxidative dye precursors are oxidized by oxidizing agents and form reactive intermediates. The couplers, which are relatively stable to oxidizing agents, react with the intermediates, leading to vibrant coloring molecules.

The hair coloring compositions herein 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 provide a ready-to-use hair coloring composition having an unusually low pH, in the range of about 6 to about 8. These hair coloring compositions unique bristles provide long-lasting color to the hairs, while being gentle and non-irritating to the skin. They are useful for coloring all hair types, including hair, eyelashes, eyebrows and body hair, but are particularly useful for coloring facial hair (beard and mustache).

Basic hair coloring compositions include:

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

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

- 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 hair coloring, based on the total weight of the basic hair coloring composition.

The pH of hair coloring base compositions 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. The pH of the ready-to-use hair coloring compositions formed with the hair coloring base compositions is about 6 to about 8, preferably about 6.1 to about 7.9, more preferably from about 6.2 to about 7.8, which is lower than most ready-to-use hair coloring compositions.

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-1-propanol, 2 -amino-2-methyl-1,3-propanediol, 3-amino-1,2-propanediol, 3-dimethylamino-1,2-propanediol, tris(hydroxymethyl)amino-methane, or mixtures thereof. Non-limiting examples of mineral alkalizing agents include ammonia, ammonium carbonates, sodium carbonates, potassium carbonates, ammonium bicarbonates, sodium bicarbonates, potassium bicarbonates, hydroxides of ammonium, sodium hydroxides, potassium hydroxides or mixtures thereof. However, in various embodiments, the base hair coloring composition is free or essentially free of ammonia and/or ammonium ions, and/or ammonium hydroxide.

Surfactants can be nonionic, anionic, amphoteric (zwitterionic) or cationic surfactants. In various embodiments, the base hair coloring compositions include one or more nonionic surfactants. In other embodiments, the hair color base compositions include one or more nonionic surfactants and one or more anionic surfactants, for example, a fatty amide (nonionic surfactant) and an ether carboxylic acid (anionic surfactant). .

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

Additional components useful in basic hair coloring compositions include fatty alcohols, surfactants, and/or water-soluble organic solvents. In some embodiments, the fatty acids have 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 of these.

In various embodiments, the base 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 chemical reaction. Non-limiting examples of reducing agents include ammonium bisulfite, ammonium sulfite, potassium metabisulfite, potassium sulfite, sodium hydrosulfite, sodium metabisulfite, sodium sulfite, sodium bisulfite sodium, thioglycolic acid, thiolactic acid, dehydroascorbic acid, a salt thereof, and a mixture thereof. In some embodiments, the hair coloring base compositions include thioglycolic acid, thiolactic acid, salts thereof, and mixtures thereof.

In addition to the previous ones, in various embodiments, the basic hair coloring composition includes:

(b) one or more couplers;

(c) less than 3% by weight, preferably less than 2.5% by weight, 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, based on the total weight of the basic hair coloring composition;

(d) one or more fatty alcohols;

(e) one or more surfactants;

(f) optionally 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% by weight, preferably at least 75% by weight weight, more preferably at least 80% by weight of the basic hair coloring composition; And

All weight percentages are based on the total weight of the base hair color composition.

In various embodiments, the hair coloring base compositions are free or substantially free of ammonia and/or ammonium ions and/or ammonium hydroxide.

Base hair coloring compositions 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 from about 6.2 to about 7.8. For example, base hair coloring compositions 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, or approximately 2:1 to approximately 1:2. The pH of hair coloring base compositions 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.

The hair coloring base compositions and the developer compositions are contained separately before mixing. Thus, both compositions can be provided in a kit. The kits according to the present disclosure include one or more base hair coloring compositions and one or more developer compositions, wherein the base hair coloring compositions and the developer compositions are contained separately. For example, the one or more base hair coloring compositions and the one or more developer compositions may be included in separate containers that are packaged together.

Methods of preparing ready-to-use hair coloring compositions and methods of coloring hair with the compositions include combining the base hair coloring composition with a developer composition to form a hair coloring composition ready to use. The ready-to-use hair coloring composition is then applied to the hairs for a period of time (for treatment), for example, from about 1 to about 30 minutes, from about 1 to about 20 minutes, or from about 1 to about 15 minutes, from about 1 to 10 minutes, or from about 1 to 5 minutes. After the period of time has elapsed, the hair coloring compositions may be removed from the hairs by rinsing or washing exposing the newly colored hairs. The newly colored hairs permanently retain their changed color, suffer little or no unwanted chemical damage, and the underlying skin is not subject to the burning and stinging associated with various oxidative coloring processes.

The implementations of the present technology will now be described, by way of example, with reference to the attached figures, in which:

There is a graph showing the color retention of 90% gray hair treated with a composition of the invention compared to hair treated with two comparative compositions; And

There is a graph showing the color retention of 90% permed hairs treated with a composition of the invention compared to hairs treated with two comparative compositions.

The figures and data they represent are non-limiting and are provided simply to illustrate certain aspects of the technology.

DETAILED DESCRIPTION

People often seek to permanently change the color of their hair using oxidative dyeing procedures. Complaints commonly associated with these procedures include inappropriate color deposition, damage to the hair and/or underlying skin, and fading of the hair over time. During the coloring process, hair coloring compositions often come into contact with the underlying skin. This can temporarily discolor the underlying skin, cause discomfort, and in some cases even damage the skin. Over time, the initial color given to the hairs may fade. As color fades, hair may appear less vibrant, exhibit unwanted tints, and appear unkempt.

The hair coloring compositions and methods of the present case address the concerns discussed above. They are gentle on the hair and underlying skin while providing a fast and powerful color deposit that is long-lasting (long-lasting). Hair coloring compositions are suitable for all hair types. However, due to their robust coloring ability and gentle nature, they are particularly well suited to coloring facial hair ( e.g. beard and mustache), which tends to be thicker than other hairs.

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 off soon after or just after birth. The “down” is short, fine and lightly colored. It develops on the body during childhood, except on the lips, palms of the hand, soles of the feet, behind the ears, inside the navel, etc. These hairs come from follicles that are not connected to an oil gland. The “terminal hairs” grow mainly on the head. They are long, thick, and darker than hairs elsewhere on the body. When a person enters puberty, terminal hair replaces the down on the pubic area and armpits. Men in particular may also develop terminal hair in place of fuzz on the chest, limbs, feet, back and face. When they develop during puberty/adolescence, they are called androgenic hairs.

Hair on the scalp, like hair on the face, 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's a matter of months. Beard and mustache hair (androgenic hair) can be very different from hair grown 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 maintain a fully colored head of hair into middle age, while the beard may become partially or completely gray. Scalp hair may be straight, however androgenic facial hair is thicker and curly, partly due to the different shape of the follicles. Follicles on the face are much more sensitive to androgens such as testosterone, which can cause the follicles to twist and lead to the growth of curly hair. The skin under androgenic facial hair is also different from the skin on the scalp.

As noted previously, hair coloring compositions intended to permanently modify hair color typically rely on a combination of two parts, a base hair coloring composition, and a developer composition. The base hair coloring 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.

Oxidative dye precursors are typically colorless or weakly colored compounds which, when combined with oxidizing agents, are converted to colored species via a process of oxidative condensation. The shades obtained with the 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.

The oxidizing agent(s) used in the permanent dye compositions can degrade the melanin of the hair, which, depending on the nature of the oxidizing agent, can lead to a 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.

In general, hair coloring compositions are alkaline, having a high pH of about 9 and above, and may generally require the presence of an alkalizing agent such as ammonia or an ammonia gas generating compound and /or an amine or ammonium-based compound in sufficient quantities to achieve the desired alkalinity. Alkalizing agents help activate oxidizing agents and cause the hair shaft to swell, allowing small molecule oxidative dye precursors to penetrate the cuticle and cortex before the oxidative condensation process is complete. The larger color complexes resulting from the oxidative reaction are then trapped inside the hair fiber, permanently changing the color of the hair.

In various embodiments, the basic hair coloring compositions of the present disclosure include:

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

(b) one or more couplers;

(c) less than 3% by weight, preferably less than 2.5% by weight, 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, based on the total weight of the basic hair coloring composition;

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

(e) about 15 to about 40% by weight of one or more surfactants;

(f) about 10 to about 40% by weight of one or more water-soluble organic solvents;

(g) about 25 to about 60% by weight water;

wherein (e), (f) and (g) are in amounts such that a combined amount of (e), (f) and (g) constitutes at least 70% by weight of the base coloring composition of the fur ; And

All weight percentages are based on the total weight of the base hair color composition.

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

The pH of the base hair coloring 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, e.g. , 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. Accordingly, to obtain a ready-to-use hair coloring composition by mixing the developer composition with the basic hair coloring composition hairs, the basic hair coloring composition should have a low pH, for example from about 7 to about 10, preferably from about 7.5 to about 9.5, more preferably from about 8 to less of 9.5. The pH of the base hair coloring composition, the pH of the developer composition, and the mixing ratio of the base hair coloring composition to the developer composition can influence the final pH of the hair coloring composition. bristles ready to use.

In various embodiments, the pH of the base hair color composition is about 7 to about 10, about 7.5 to about 10, about 8 to about 10, 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, about 7 to about 9, about 7.5 to about 9, or about 8 to about 9.

In various embodiments, the hair coloring base compositions are free or essentially free of resorcinol and/or resorcinol derivatives. The hair color modification 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 embodiments, the hair color modifying 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.

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 base hair coloring compositions of the present disclosure are such that they form a ready-to-use hair coloring composition having a pH of about 6 to about 8, of about 6 .1 to about 7.9, or from 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).

Furthermore, the total amount of alkalizing 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 use, the total amount of alkalizing 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.

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

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

(b) approximately 82% by weight water;

(c) approximately 0.5% by weight of glycerin;

The one or more base hair coloring compositions may be combined with the one or more developer compositions in a ratio of about 1:5 to about 5:1 (base hair coloring composition:developer composition). In some cases, the weight ratio is from about 1:4 to about 4:1, from about 1:3 to about 3:1, from about 1:2 to about 2:1, or from about 1: 1 (basic hair coloring composition: developer composition), provided that the pH of the ready-to-use hair coloring composition has the desired pH.

Methods for coloring hair, particularly facial hair (beard and/or mustache) include applying a ready-to-use hair coloring composition of the present disclosure to the hair. The ready-to-use hair coloring composition may be prepared as described above, namely , by combining one or more hair coloring base compositions according to the present disclosure with one or more developer compositions. The ready-to-use hair coloring composition is typically used (applied to the hair) shortly after formation, i.e. shortly after the base hair coloring composition has been combined with the developer composition to form a composition 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 after formation. In other embodiments, the ready-to-use hair coloring composition is applied immediately after training until about 1 hour after training, until about 45 minutes after training, until about 30 minutes after training or until approximately 15 minutes after training.

The ready-to-use hair coloring composition may be applied to hair, 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, e.g., bleached, previously colored, previously permed, previously straightened, etc. In other embodiments, the hair to be treated (colored) includes natural gray hair, that is to say hair which has developed a loss of natural pigmentation and/or melanin.

After application to the hairs, the ready-to-use hair coloring composition is allowed to sit on the hairs for a period of time, e.g., a period of time sufficient to achieve a desired change in hair color . For example, the ready-to-use hair coloring composition may be left to sit on the hairs 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 approximately 30 minutes, approximately 1 minute to approximately 15 minutes, approximately 2 minutes to approximately 1 hour, approximately 2 minutes to approximately 45 minutes, approximately 2 minutes to approximately 30 minutes, approximately 2 minutes to approximately 15 minutes, approximately 2 minutes to approximately 10 minutes, approximately 3 minutes to approximately 30 minutes, approximately 3 minutes to approximately 25 minutes, approximately 3 minutes to approximately 20 minutes, approximately 3 minutes to about 15 minutes, from about 3 minutes to about 10 minutes, or from about 5 minutes to about 10 minutes. One skilled in the art, by considering various factors such as the initial and desired color of the hairs, will be able to determine an appropriate length of time for leaving the ready-to-use hair coloring composition on the hairs to achieve the desired result. After the ready-to-use hair coloring composition has been allowed to sit on the hairs for a period of time, the ready-to-use hair coloring composition may optionally be removed from the hairs by rinsing or cleaning (for example, subjected to shampoo).

EXAMPLE 3 (Tenacity study)

The base hair coloring compositions 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 basic hair coloring compositions E, F and G of Example 1 are identical with the exception of the quantity of ethanolamine. The higher amounts of ethanolamine included in the base hair color compositions F and G caused these compositions to have a higher pH than the base hair color composition E. The three hair color compositions ready to employment are summarized in the table below.

Each of the three hair coloring compositions was mixed with 20 V International Developer at a mixing ratio of 1:1. This mixture was applied to strands of 90% gray hair, which are commercially available. The mixtures were left to sit on the hair of the strands (to be treated) for 5 minutes before being rinsed from the hair with water. The hair strands were then washed with a standard sulfate-based hair cleansing composition. The washing and rinsing procedure was repeated for 15 cycles, i.e. , the hair strands were washed with the standard sulfate-based hair cleaning composition and then dried for 15 consecutive times. Color measurements were taken and images of the strands were captured before application, after initial treatment with the ready-to-use hair coloring compositions, as well as after 5, 10 and 15 washes.

Color retention on hair strands was assessed based on washing using CIE L*a*b* coordinates. ΔE represents color difference, where a higher ΔE value represents increased color fading or reduced color retention. ΔE is defined by the following equation:

where L*, a* and b* represent the values measured after a treatment, and L0*, a0* and b0* represent the values measured before a treatment(s).

Hair color was analyzed before treatments with the ready-to-use hair coloring composition; immediately after initial treatment with ready-to-use hair coloring compositions; and after being washed 5, 10 and 15 times. The results are shown on the .

As illustrated by the data, 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 gray hair than ready-to-use hair coloring composition #3 having a higher pH of 10 (prepared using hair coloring base composition G ).

EXAMPLE 4 (Tenacity study)

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

As illustrated by the data, 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 color composition #3 having a higher pH of 10 (prepared using the base hair color composition G ).

Definitions

The term “hair” as used herein includes hair, beard hair, mustache hair, eyebrows, eyelashes, and body hair, unless otherwise indicated.

The term “beard hair” includes mustache hair unless otherwise stated.

As used herein, the terms “comprising”, “having” and “including” are understood 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. job.

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 hair coloring composition. bristles ready to use.

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 base hair coloring composition with a developer composition.

A “composition dye” is a compound that colors the composition but does not have an appreciable coloring effect on the hair. In other words, the composition colorant is included to give color to the composition, for example, for aesthetic appearance. It is not included to give color to the hair. Styling gels, for example, can be found in a variety of different colors ( e.g. , light blue, light pink, etc.), but applying the styling gel to the hair does not change the hair color.

The term "oil" is used here to refer to an organic compound that is insoluble in water at normal temperature (25°C) and atmospheric pressure (760 mmHg), i.e. it has lower water solubility at 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 comprising at least 6 carbon atoms. Furthermore, oils are generally soluble in organic solvents under the same temperature and pressure conditions, for example in chloroform, ethanol, benzene or decamethylcyclopentasiloxane. Additionally, oils are liquid at ordinary temperature (25°C) and atmospheric pressure (760 mmHg). The oils preferably do not contain carboxylic acid functions, i.e. 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 the present disclosure, the compositions may nevertheless be free or essentially free of fatty compounds of oils (since fatty alcohols are not included in the definition of fatty compounds and oils).

Throughout the disclosure, the expression "a mixture thereof" is used, after a list of elements as shown in the following example where the letters A through 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 phrase "a mixture thereof" does not require that the mixture include all elements A, B, C, D, E and F (although all elements A, B, C, D, E and F may be included). Rather, it indicates that a mixture of two or more of elements A, B, C, D, E and F can be included. In other words, it is equivalent to the formulation "one or more elements 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”.

Likewise, the expression "a salt thereof" also refers to "salts thereof". Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or a mixture thereof", 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.

The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures/combinations.

Some of the various component categories identified 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 represents no more than one component. For example, a fatty acid can 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).

Salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, an alkaline earth metal or an ammonium counterion. This list of counterions is, however, not exhaustive.

The term "treat" (and grammatical variations thereof) are used herein to refer to the application of the compositions of the present disclosure to the surface of keratinous substrates such as hair. The term "treat" (and grammatical variations thereof) are used herein also to refer to the contacting of keratinous substrates such as hair with the compositions of the present disclosure.

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. So a range of 1-5 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 herein that falls within a range described herein may be used as a minimum or maximum value to derive a subrange, etc.

The term "substantially free" or "substantially free" as used herein means that less than about 2% by weight of a specific material is added to a composition, based on 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 presented herein may be optionally included or excluded from the compositions/processes/requirements. When excluded, the compositions/processes/kits may be free or essentially free of the component. For example, a particular composition may be free or essentially free of alkoxylated compounds, for example, ethoxylated thickeners and/or ethoxylated surfactants. Likewise, a particular composition may be free or essentially free of sulfates, such as sulfate surfactants.
