Description

Title of Invention: Hair Treatment Composition and Methods for Straightening Hair FIELD OF DISCLOSURE

[0001] The present disclosure relates to hair treatment compositions and methods of treating hair with the hair treatment compositions. The treated hair is resistant to heat damage and exhibits improved fiber alignment, frizz control, and smooth texture. BACKGROUND

[0002] Many consumers use cosmetic and care compositions to enhance the appearance of hair, for example, by changing the color, style and / or shape of the hair and / or by imparting various cosmetic properties to the hair, such as shine and conditioning. Hair can become dry or damaged for various reasons, for example, exposure to the elements, poor nutrition, mechanical treatments (e.g., brushing the hair), styling treatments using chemicals, dyeing, heat, nutrition, etc. Even cleansing products can remove the natural sebum from the hair, which can lead to dryness, dullness and split ends.

[0003] Chemical hair treatments include bleaching and coloring treatments to change the color of the hair. Chemical treatments also include processes to permanently change the shape and structure of the hair, for example, by perming, waving, relaxing, or straightening the hair. These chemical treatments change the appearance of the hair by changing its physical structure, which inevitably causes some degree of damage to the hair. Environmental factors, such as salt water, sunlight, and heat, are also known to damage hair. Damaged hair is characterized by unnatural changes in the protein structure of individual hair strands or shafts.

[0004] The popularity and use of oils for hair treatment has increased due to their effectiveness and simplicity. Commonly used oils include olive oil, mineral oil, avocado oil, apricot kernel oil, rice bran oil, and coconut oil. However, these treatments can make hair greasy. In addition, the effects are usually not seen after several hours (e.g., 8 hours) of treatment, and multiple treatments are usually required, which is time-consuming and labor-intensive.

[0005] Hair damage leads to split ends, dryness, Hair that breaks easily and becomes frizzy and difficult to style. Because the visible part of the hair is dead, it cannot regenerate itself. Many over-the-counter and salon treatments claim to repair damaged hair. These include conditioners, hot oil treatments, hydrolyzed proteins, vitamin formulations, and extracts of exotic fruits, leaves, or roots. However, these treatments provide little improvement to the hair. Therefore, hair treatment technologies that can straighten, relax, or style hair without chemically damaging it are desired.

[0006] There continues to be a need to provide improved hair manageability, for example, improved hair alignment, reduced unwanted volume (including reduced frizz), and improved smooth texture and shine, while simultaneously protecting the hair from damage caused by heat treatments.

[0155] (d) Non-ionic associative polymeric thickeners

[0156] An associative thickener is capable of reversibly associating with itself or with other molecules or particles. This physical association provides thickening and can give rise to thixotropic or shear-thinning macromolecular systems, that is, systems whose viscosity depends on the shear forces to which they are subjected.

[0157] In various embodiments, the non-ionic associative polymeric thickener is a non-ionic associative polyurethane thickener, preferably a non-ionic associative polyurethane / polyether. The non-ionic polyurethanes / polyethers may have both at least one hydrophilic moiety and at least one hy drophobic. More particularly, said polymers may contain in their chain both hydrophilic sequences, most often of a polyoxyethylenated nature, and hydrophobic sequences which may be aliphatic bonds alone and / or cycloaliphatic and / or aromatic bonds. In various embodiments, these polyether-polymethanes comprise at least two lipophilic hydrocarbon chains, having from 6 to 30 carbon atoms, preferably from 6 to 20, separated by a hydrophilic sequence, knowing that the hydrocarbon chains may be pendant chains or chains at the end of a hydrophilic sequence. In particular, it is possible that one or more pendant chains are envisaged. In addition, the polymer may comprise a hydrocarbon chain at one end or at both ends of a hydrophilic sequence.

[0158] Polyether polyurethanes may be polyblocks, particularly in triblock form. The hydrophobic sequences may be at each end of the chain (for example: triblock copolymer carrying a hydrophilic central block) or distributed both at the ends and in the chain (for example, polyblock copolymers). These same polymers may also be in the form of graft units or be star-shaped.

[0159] Nonionic polyether / polyurethanes containing a fatty chain may be triblock copolymers whose hydrophilic block is a polyoxyethylenated chain comprising from 50 to 1000 oxyethylenated groups. Nonionic polyether polyurethanes comprise a methane bond between the hydrophilic blocks, hence the origin of the name. By extension, those whose hydrophilic blocks are linked by other chemical bonds to the hydrophobic blocks are also included among the nonionic polyether-polyurethanes containing a hydrophobic chain.

[0160] Non-limiting examples of non-ionic polyethers / polyurethanes containing a hydrophobic chain include Rheolate® 205 containing a urea functional group sold by RHEOX or alternatively Rheolates® 208, 204 or 212, as well as Acrysol RM 184®. Other products include ELFACOS T210® containing a C12-C14 alkyl chain and ELFACOS T212® product containing a C18 alkyl chain from AKZO. ROHM & HAAS DW 1206B® product containing a C20 alkyl chain and a methane linkage, sold at 20% solids in water, may also be used.

[0161] It is also possible to use solutions or dispersions of these polymers, in particular in water or in an aqueous-alcoholic medium. Examples of these polymers include Rheolate® 255, Rheolate® 278 and Rheolate® 244 sold by the company Rheox. It is also possible to use the products DW 1206F and DW 1206J supplied by the company ROHM & HAAS.

[0162] As polyethers / polyurethanes described above, mention may be made of polyurethanes / po- lyethers comprising in their chain at least one polyoxyethylenated hydrophilic block and at least one of hydrophobic blocks containing at least one sequence chosen from aliphatic sequences, cycloaliphatic sequences and aromatic sequences. In various embodiments, it is preferable that the polyurethanes / polyethers comprise at least two lipophilic chains based on hydrocarbons having from 8 to 30 carbon atoms, separated by a hydrophilic block, and in which the hydrocarbon-based chains are chosen from pendant chains and chains at the end of the hydrophilic block.

[0163] In a preferred embodiment, a polyurethane / polyether is used which can be obtained by polycondensation of at least three compounds comprising (i) at least one polyethylene glycol comprising from 150 to 180 mol of ethylene oxide, (ii) a polyoxyethylenated stearyl alcohol comprising 100 mol of ethylene oxide, and (iii) a dii-isocyanate. These polyurethanes / polyethers are notably sold by the company Elément under the name Rheolate FX 1100® and Rheoluxe 811®, which is a polycondensate of polyethylene glycol containing 136 mol of ethylene oxide, polyoxyethylenated stearyl alcohol with 100 mol of ethylene oxide and hexamethylene diisocyanate (HDI) with a weight average molecular weight of 40,000 (INCI name: PEG-136 / Steareth-100 / HDI Copolymer).

[0164] According to another embodiment, a polyurethane / polyether will be used which can be obtained by polycondensation of at least three compounds comprising (i) at least one polyethylene glycol comprising from 150 to 180 moles of ethylene oxide, (ii) stearyl alcohol or decyl alcohol, and (iii) at least one diisocyanate. These polyurethanes / polyethers are sold in particular by the company Rohm & Haas under the names Aculyn 46® and Aculyn 44®.

[0165] Aculyn 46® bearing the INCI name: PEG-150 / Stearyl Alcohol / SMDI Copolymer, is a polyethylene glycol polycondensate comprising 150 or 180 mol of ethylene oxide, stearyl alcohol and methylenebis(4-cyclohexyl isocyanate) (SMDI) at 15% by weight in a matrix of maltodextrin (4%) and water (81%) (INCI name: PEG-150 / Stearyl Alcohol / SMDI Copolymer). Aculyn 44® (PEG-150 / Decyl Alcohol / SMDI Copolymer) is a polyethylene glycol polycondensate comprising 150 or 180 mol of ethylene oxide, decyl alcohol and methylenebis(4-cyclohexyl isocyanate) (SMDI) at 35% by weight in a mixture of propylene glycol (39%) and water (26%) (INCI name: PEG-150 / Decyl Alcohol / SMDI Copolymer).

[0166] As associative polyurethanes, it may be preferable to use a compound represented by the following formula (1):

[0167] R1 -{(O-R2)k -OCONH-R3 [-NHCOO-(R4 -O)n -R5 ]h}m (1)

[0168] in which R1 represents a hydrocarbon group, R2 and R4 represent independent during alkylene groups having 2 to 4 carbon atoms, which groups alkylene may be the same as or different from each other, or a phenylethylene group, R3 represents a hydrocarbon group, which may optionally have a urethane linkage, R5 represents a branched chain or secondary hydrocarbon group, "m" represents a number of at least 2, "h" represents a number of at least 1, "k" represents a number in the range of 1 to 500, and "n" represents a number in the range of 1 to 200.

[0169] The hydrophobically modified polyurethane represented by the general formula (1) shown above is obtained, for example, by reacting at least one polyether polyol which is represented by the formula R1 -[(O-R2)k -OH]m, at least one polyisocyanate which is represented by the formula R3 -(NCO) h+b and at least one polymonoalcohol which is represented by the formula HO-(R4 -O)n -R5. In such cases, R1 to R5 in the general formula (1) are determined by the compounds R1—[(O—R2)k—OH]m, R3—(NCO) h+i and HO—(R4—O)n—R5. The charge ratios among the three compounds are not particularly limited and should preferably be such that the ratio of the isocyanate group derived from the polyisocyanate to the hydroxyl group derived from the polyether polyol and the polyether monoalcohol is selected from the NCO / OH range of 0.8:1 to 1.4:1.

[0170] The polyether polyol compound which is represented by the formula R1—[(O—R2)k—OH]m and which can be preferentially used to obtain the associative thickener represented by the general formula (1) can be obtained by addition polymerization of an m-hydric polyol with an alkylene oxide, such as ethylene oxide, propylene oxide, butylene oxide, or epichlorohydrin, or with styrene oxide, and the like.

[0171] The polyols should preferably be di- to octahydric polyols.Examples of di- to octahydric polyols include dihydric alcohols, such as ethylene glycol, propylene glycol, butylene glycol, hexamethylene glycol, and neopentyl glycol; trihydric alcohols, such as glycerol, trioxy isobutane, 1,2,3-butanetriol, 1,2,3-pentanetriol, 2-methyl-1,2,3-propanetriol, 2-methyl-2,3,4-butanetriol, 2-ethyl-1,2,3-butanetriol, 2,3,4-pentanetriol, 2,3,4-hexanetriol, 4-propyl-3,4,5-heptanetriol, 2,4-dimethyl-2,3,4-pentanetriol, penta-methylglycerol, pentaglycerol, 1,2,4-butanetriol, 1,2,4-pentanetriol, trimethylolethane, and trimethylolpropane; tetrahydric alcohols, such as pentaerythritol, 1,2,3,4-pentanetetrol, 2,3,4,5-hexanetetrol, 1,2,4,5-pentanetetrol and 1,3,4,5-hexanetetrol; pentahydric alcohols, such as adonitol, arabitol and xylitol; hexahydric alcohols, such as dipentaerythritol, sorbitol, mannitol and iditol; and octahydric alcohols, such as sucrose.

[0172] Also, R2 is determined by alkylene oxide, styrene oxide or the like, which is subjected to addition. In particular, for availability and excellent effects, an alkylene oxide having 2 to 4 carbon atoms, or styrene oxide is preferable.

[0173] The alkylene oxide, styrene oxide, or the like, to be subjected to addition may be subjected to single polymerization, or random polymerization, or block polymerization of at least two members. The addition procedure may be a conventional procedure. Also, the degree of polymerization k may be selected in the range of 0 to 1000, preferably in the range of 1 to 500, and more preferably in the range of 10 to 200. Furthermore, the ratio of the ethylene group occupying R2 should preferably be in the range of 50 to 100% by mass relative to the total amount of R2. In such cases, the associative thickener suitable for the purposes of the present invention is obtained.

[0174] Furthermore, the molecular weight of the polyether polyol compound which is represented by the formula R1—[(O—R2)k—OH]m, should preferably be selected in the range of 500 to 100,000, and should more preferably be selected in the range of 1,000 to 50,000.

[0175] The polyisocyanate which is represented by the formula R3—(NCO)h+i and which can be preferentially used to obtain the hydrophobically modified polyether urethane represented by the general formula (1) employed in accordance with the present invention is not limited, particularly to the extent that the polyisocyanate has at least two isocyanate groups in the molecule. Examples of polyisocyanates include aliphatic diisocyanates, aromatic diisocyanates, alicyclic diisocyanates, biphenyl diisocyanate, phenylmethane diisocyanate, phenylmethane triisocyanate and phenylmethane tetraisocyanate.

[0176] It is also possible to use dimers and trimers (isocyanuric bonds) of the polyisocyanates listed above. In addition, it is possible to use biuret obtained by reaction with an amine.

[0177] Furthermore, it is possible to use a polyisocyanate having a urethane bond obtained by reacting said polyisocyanate compound and a polyol. As the polyol, di- to octahydric polyols are preferable, and the polyols listed above are preferable. In cases where a trihydric or higher polyisocyanate is used as the polyisocyanate which is represented by the formula R3—(NCO)n+1, it is preferable to use said polyisocyanate having the urethane bond.

[0178] The polyether monoalcohol which is represented by the formula HO—(R4—O)n—R5 and which can be preferably used to obtain the hydrophobically modified polyether urethane represented by the general formula (1) employed in accordance with the present invention is not limited, particularly to the extent that the polyether monoalcohol is a polyether of a straight chain, a branched chain or a secondary monohydric alcohol. The polyether monoalcohol can be obtained by addition polymerization of the straight chain, the branched chain or the monohydric alcohol secondary hydrochloric acid with an alkylene oxide, such as ethylene oxide, propylene oxide, butylene oxide or epichlorohydrin, or with styrene oxide, and the like.

[0179] The compound represented by general formula (1) can be produced, for example, by heating at a temperature of 80 to 90°C for 1 to 3 hours and thereby causing a reaction occurring in the same manner as that in the ordinary reaction of a polyether and an isocyanate.

[0180] As a compound represented by general formula (1), polyethylene glycol-240 / decyltetradeceth-20 / hexamethylene diisocyanate copolymer is preferable. Polyethylene glycol-240 / decyltetradeceth-20 / hexamethylene diisocyanate copolymer is also called PEG-240 / HDI bis-decyltetradeceth-20 ether copolymer.

[0181] In various embodiments, it is preferable that the non-ionic associative polyurethane thickener is selected from the steareth-100 / PEG-136 / HDI copolymer sold by the company Rheox under the name Rheolate FX 1100, the PEG-240 / HDI bis-decyltetradeceth-20 ether copolymer sold by the company Asahi Denka under the name Adekanol GT-700, and mixtures thereof.

(e) Non-ionic surfactants or emulsifiers

[0183] The terms "nonionic surfactant" and "nonionic emulsifier" are used interchangeably in the present disclosure and may therefore be referred to as "nonionic emulsifying surfactants." The nonionic surfactant or emulsifier may have an HLB (hydrophilic-lipophilic balance) ranging from 1 to 7.9 or greater than or equal to 8. "HLB" refers to the "hydrophilic-lipophilic balance" associated with nonionic surfactants or emulsifiers. In particular, the "HLB" value relates to the ratio of hydrophilic groups to lipophilic groups in the emulsifiers, as well as the solubility of the emulsifiers. Emulsifiers with lower HLB (such as those with HLB values ​​ranging from 1 to 7.9) are more soluble in oils (lipophilic material) and are more suitable for use in water-in-oil (W / O) emulsions.Higher HLB emulsifiers (such as those with HLB values ​​above 8) are more soluble in water (hydrophilic material) and are more suitable for . oil-in-water (O / W) emulsions.

[0277] wherein all weight percentages are based on a total weight of the hair treatment composition.

[0278] The pH of the composition may vary. However, in various embodiments, a pH of less than 7 (an acidic pH) is desirable. For example, the pH may be from about 3 to about 6.5, from about 3 to about 6, from about 3 to about 5.5, from about 3 to about 5, from about 3 to about 4.5, from about 3.5 to about 6.5, from about 3.5 to about 6, from about 3.5 to about 5.5, from about 3.5 to about 5, or from about 3.5 to about 4.5. Methods

[0279] As explained throughout the present disclosure, the hair treatment compositions are particularly useful in methods of treating hair, preferably human hair, particularly human head hair. Treatment with the compositions improves fiber alignment, reduces frizz, and imparts a smooth texture to the hair. The methods typically comprise applying a hair treatment composition of the present disclosure to the hair. The hair is preferably wet or damp, but the composition can also be applied to dry hair. Applying the compositions to the hair will moisten the hair because the compositions are aqueous (containing a large portion of water). Therefore, after distributing by massage or spread the composition throughout the hair, without rinsing the composition from the hair, the hair can be dried, for example, the hair can be dried using a hair dryer. Once the hair is dry, it can be treated with a thermal treatment (treated with heat). For example, the hair can be treated with a hot iron, in particular, a flat iron. Typically, the hot iron is passed over the hair at least once, at least twice, at least three times, or more.

[0280] In other embodiments, prior to treating the hair with the hair treatment compositions of the present disclosure, the hair is treated with a hair straightening or relaxing composition. Various straightening and relaxing compositions are known in the art. For example, chemical straightening procedures utilize a hydroxide relaxer in a process called lanthio-nization, which breaks disulfide bonds and alters the curl pattern of the hair. During this process, the curl pattern is loosened or relaxed. The cortex is thus elongated, stretching the original curl pattern, making it a permanent change. There are several types of hydroxide relaxers that contain active ingredients such as sodium hydroxide (NaOH), potassium hydroxide (KOH), and lithium hydroxide (LiOH).Sometimes calcium (Ca(OH)2 ) is added to hydroxide relaxers, but it is not used only for straightening hair. The composition can be used on hair treated with a straightening or straightening composition, but is not limited to such treatment. It can be used on hair previously treated with an acid system (hydroxide relaxer) or an acid system.

[0281] In various embodiments, hair is treated with a hair smoothing composition comprising glyoxylic acid prior to treatment with the compositions of the present disclosure. Glyoxylic acid provides smoothing benefits to hair fibers without breaking the cystine disulfide bond. Therefore, it provides long-lasting smoothing effects without damaging the hair and scalp, which is more common with alkaline chemicals and other smoothing agents. The carboxylic and aldehyde groups of glyoxylic acid react with amine groups in hair keratin, resulting in the formation of stable bonds.

[0282] Hair straightening or relaxing compositions comprising glyoxylic acid typically have a pH of about 2.5 to about 5. Unlike alkaline compositions, hair straightening or relaxing compositions comprising glyoxylic acid have an acidic pH. In various embodiments, the pH of the hair straightening composition is about 2.5 to about 4.5, about 2.5 to about 4, about 2.5 to about 3.5, or about 2.8 to about 3.2. The com Hair straightening or relaxing compositions may be applied to the hair, left on the hair for a period of time (e.g., 1-30 min, 1-20 min, 1-10 min, 5-30 min, 5-25 min, 5-20 min, 5-15 min, 10-30 min, 10-25 min, 10-20 min, or 10-15 min), and then rinsed from the hair. After rinsing the hair treatment composition, the hair may optionally be treated with a conditioning composition. Thereafter, the hair treatment compositions of the present disclosure are applied to the hair as a leave-in product. After the compositions of the present disclosure are massaged or incorporated into the hair, the hair is dried and treated with a hot iron, such as a flat iron, at a temperature of about 150°C to about 300°C, preferably 150°C to about 250°C, more preferably about 180°C to about 230°C.

[0283] The treated hair is also soft, shiny, revitalized, and healthy-looking. The compositions include a unique combination of a cyclic carbonate and an amino-functionalized silicone, which forms a smooth coating on the surface of the hair. The smooth coating is surprisingly durable. The improved cosmetic properties imparted to the hair are long-lasting and are maintained even after multiple wash cycles.

[0284] An implementation of the present disclosure is provided by means of the following examples. These examples serve to illustrate the technology without being limiting in nature. Example 1 (Compositions)

[0288] 3 Viscosity was estimated based on data from sample C. Example 2 (Essays)

[0289] The compositions in the table of Example 1 were incorporated into a hair treatment routine and the resulting cosmetic attributes of the hair subjected to the routine were compared. The routine was performed using strands of medium-bleached curly hair with a curl pattern of 4 (André Walker scale of hair with a curl pattern of 2C-3A). All strands of hair were first cleansed with a standard shampoo. After cleansing, the strands of hair were subjected to the following routine.

[0290] 1. The hair strands were treated with a hair smoothing composition hair containing glyoxylic acid. Glyoxylic acid provides semi-permanent hair straightening without breaking the cystine disulfide bond in the hair fibers. It provides long-lasting straightening effects to the hair, without damaging it or causing scalp irritation. The hair straightening composition was applied to damp hair strands, massaged into the hair fibers, and left on the hair for 10 minutes. After 10 minutes, the hair straightening composition was rinsed from the hair strands. Details of the hair straightening composition are shown in the table below.

[0292] 2. The hair strands were then treated with an anhydrous rinse which deposits a uniform film of conditioning agents on the hair fiber. The anhydrous rinse was applied to strands of damp hair, distributed by massage into the strands of hair and immediately rinsed from the hair.

[0294] 3. The strands of hair were then treated with one of the compositions of Example 1 (A, B or C). The compositions of Example 1 (A, B or C) were individually massaged into strands of hair and left on the hair (they were not rinsed from the hair).

[0295] 4. After applying the compositions of Example 1 (A, B or C), the locks of Hair was blow-dried and treated with a flat iron at a temperature of 200°C. The hot iron was passed over the strands of hair three times.

[0296] 5. The hair strands were then washed with a standard shampoo and treated with a standard rinse-out conditioner. The shampoo-conditioner cycle was performed 12 consecutive times

[0297] The hair strands subjected to the above routine were evaluated and compared with each other. The reference strands were prepared by simply cleaning them with the standard shampoo and allowing them to air dry. The hair strands are all first shampooed to bring out their natural curl pattern because the hair strands received from the supplier are packaged and shipped, which compresses the strands and disrupts the natural curl pattern of the hair. As a control, the hair strands were blow-dried and treated with a hot iron at a temperature of 200°C (3 passes), but not subjected to treatment with the hair straightening composition, an anhydrous rinse, and the compositions in Table 1. The control strands were simply cleaned with the standard shampoo, blow-dried, and treated with the hot iron.

[0298] Strands treated with Inventive Composition A exhibited the best fiber alignment, the lowest degree of frizz (best frizz control), and the greatest smooth texture, as illustrated in the Figure. Strands of hair treated with Inventive Composition A exhibited a surprising degree of fiber alignment, a surprising degree of frizz reduction, and a surprising degree of smooth texture. The data show that when the composition of Example 1 is devoid of amino-functionalized silicone (Comparative Composition B) or is devoid of propylene carbonate (Comparative Composition C), the same degree of alignment, frizz reduction, and smooth texture is not achieved.Unlike the hair strands treated with Inventive Composition A, the hair strands treated with Comparative Composition A and Comparative Composition B did not show appreciable fiber alignment, suffered from frizz, and did not have a smooth appearance and feel. In fact, the control strands (cleansed, blow-dried, and flat-ironed) showed better fiber alignment, less frizz, and were softer than the hair strands treated with Comparative Compositions B and C. This . illustrates the significance of the results achieved using Inventive Composition A.

[0299] The foregoing description illustrates and describes the disclosure. In addition, the disclosure shows and describes only the preferred embodiments. However, as mentioned above, it is to be understood that it is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concepts as expressed herein, consistent with the above teachings and / or the skill or knowledge of the relevant art. The embodiments described herein are further intended to explain the best modes known to the applicant and to enable others skilled in the art to utilize the disclosure in such or other embodiments and with the various modifications required by the particular applications or uses thereof.Accordingly, the description is not intended to limit the invention to the form disclosed herein. The appended claims are also intended to be construed as including alternative embodiments.

[0300] As used herein, the terms "comprising," "having," and "including" are used in their broad and non-limiting sense.

[0301] The terms "a," "an," "the," and "the" are understood to encompass both the plural and the singular. Thus, the expression "a mixture thereof" also relates to "mixtures thereof." 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 expression "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 two or more of A, B, C, D, E, and F may 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".

[0302] Similarly, the expression "a salt thereof" also relates to "salts thereof". Thus, when the disclosure refers to "a member selected from the group consisting of A, B, C, D, E, F, a salt thereof, and 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.

[0303] Salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, alkali metal, or aryl metal counterion. earthy or ammonium. This list of counterions, however, is not exhaustive. Suitable counterions for the components described herein are known in the art.

[0304] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0305] The term “plurality” means “more than one” or “two or more.”

[0306] Except in working examples, or if otherwise indicated, all numbers expressing amounts of ingredients and / or reaction conditions may be modified in all cases by the term "about", meaning to within + / - 5% of the number indicated.

[0307] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.

[0308] Some of the various identified component categories may overlap. In such cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping compound does not represent more than one component. For example, some compounds may be considered both a nonionic surfactant or emulsifier and a fat component. If a particular composition includes both a nonionic surfactant or emulsifier and a fat compound, a single compound will serve solely as the nonionic surfactant or emulsifier or solely as the fat component (the single compound does not serve as both a nonionic surfactant or emulsifier and a fat component).

[0309] A "rinse-out" product refers to a composition that is rinsed and / or washed from the hair with water after or during application of the composition to the hair, and before drying and / or styling the hair. At least a portion of the composition is removed from the hair during rinsing and / or washing.

[0310] A "leave-in" product refers to a composition that is not rinsed and / or washed out of the hair after or during application of the composition to the hair. The composition remains on the hair during drying and / or throughout styling.

[0311] As used herein, 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 of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 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 serve as a minimum or maximum value to derive a subrange, etc.

[0312] The composition of the present case optionally includes one or more surfactants and / or emulsifiers, for example, one or more nonionic, anionic, cationic and / or amphoteric / zwitterionic surfactants. The terms "surfactants" and “Emulsifiers” include salts of surfactants and emulsifiers even if not explicitly stated. In other words, whenever the disclosure refers to a surfactant or emulsifier, it is intended that salts also be encompassed to the extent that such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in all instances throughout the disclosure), for example, by using language such as “a salt thereof” or “their salts.” Sodium and potassium are common cations that form salts with surfactants and emulsifiers. However, additional cations such as ammonium ions, or alkanolammonium ions such as monoethanolammonium or triethanolammonium ions, may also form surfactant salts.

[0313] The term "substantially free" or "essentially 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.

[0314] Any components positively presented in the present disclosure may be negatively excluded from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure.
