CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims benefit of U.S. Ser. No. 63/273,194 filed Oct. 29, 2021, and benefit of French Application No. FR 2200201, filed on Jan. 12, 2022, which are incorporated herein by reference in their entirety. 
    
    
     FIELD OF THE DISCLOSURE 
     The present disclosure relates to hair-treatment compositions and methods for treating hair with the hair treatment compositions. 
     BACKGROUND 
     Many consumers desire to use cosmetic and care compositions that enhance the appearance of keratinous substrates such as hair, e.g., by changing the color, style, and/or shape of the hair, and/or by imparting various cosmetic properties to hair, such as shine and conditioning. Hair can become dry or damaged for various reasons, e.g., weather exposure, poor nutrition, mechanical treatments (e.g. brushing hair), styling treatments using chemicals, dying, heat, nutrition, etc. Even cleansing products can remove hair&#39;s natural oils causing dryness, which can lead to a dull appearance and to split ends. 
     Chemical treatments include, for example, hair bleaching and coloring, permanents, waving products, and relaxing treatments (straightening treatments). These chemical treatments change the look of hair by changing its physical structure, which inevitably causes a certain 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 to the protein structure of the individual hair strands or shafts. Damage results in split ends, dry straw-like hair, hair that is easily broken, and hair that is “frizzy” and unmanageable. Because the visible portion of hair is dead, it has no ability to regenerate itself. There are numerous over the counter and salon treatments that purport to repair damaged hair. These include conditioners, hot oil treatments, hydrolyzed proteins, vitamin formulations, and exotic fruit, leaf, or root extracts. These treatments, however, provide only limited improvement to the hair. Therefore, hair repair technologies that restore the properties of hair back to their natural level are desired. 
     The popularity and usage of oils for dry hair treatments 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 leave the hair feeling greasy. In addition, the effects are not usually seen after more than several hours (e.g. 8 hours) of treatment and several treatments are usually required, making it time consuming and labor intensive. 
     There is still a need for providing improved manageability of hair, for example, improved hair alignment, reduced unwanted volume (especially reduced frizz), and increased shine. There is also a need to develop hair care products that can impart other benefits at the same time in addition to caring and conditioning benefits, such as styling, volume, shaping, and curl definition (for curly or wavy hair). 
     SUMMARY OF THE DISCLOSURE 
     The instant disclosure relates to hair treatment compositions and methods that provide advantageous effects to hair. For example, the hair treatment compositions improve cosmetic attributes such as softness, shine, conditioning, and healthy appearance. The hair treatment compositions include cationic polymers and nonionic polymers; and include citric acid, a salt thereof, or a combination thereof. The inventors found that the ratio of cationic polymers to nonionic polymers and the citric acid, salt thereof, or combination thereof influences the stability and the desirable cosmetic properties of the compositions. 
     The hair treatment compositions of typically includes: 
     (a) one or more fatty alcohols; 
     (b) one or more cationic surfactants; 
     (c) one or more cationic polymers; 
     (d) one or more nonionic polymers; 
     (e) citric acid, a salt thereof, or a combination thereof; and 
     (f) water;
         wherein all weight percentages are based on the total weight of the composition.       

     The weight ratio of the one or more cationic polymers (c) to the one or more nonionic polymers (d) is typically from about 2.9:1 to 1:2.9. In addition, the pH of the composition is typically from about 3 to about 6. 
     Silicones can optionally be included in the hair treatment compositions but preferably the compositions are free or essentially free from silicones. Silicones are synthetic polymers made up of repeating units of siloxane, elemental silicon and oxygen, combined with other elements, most often carbon and hydrogen. Thus, silicones are also called polysiloxanes. In some instances, the hair treatment compositions of the instant case can be free or essentially free from dimethicones, amomdimethicones, dimethiconols, cyclosiloxanes, siloxanes, etc. 
     The hair treatment compositions are aqueous compositions and are typically in form of an oil-in-water emulsion. The fatty alcohols, and optionally additional fatty materials (referred to as “fatty compounds”) primarily form the fatty phase of the emulsion. The aqueous phase is formed by water, and optionally may include one or more water-soluble solvents. The compositions typically include high amounts of water, for example, at least 50% by weight, preferably at least 60% by weight, and more preferably, at least 65% by weight. 
     Fatty alcohols, as is well known in the art, are aliphatic alcohols, for example, primary alcohols having a carbon chain from about 8 to about 30 carbon atoms, preferably from about 12 to about 22 carbon atoms.

Non-limiting examples include polysaccharides, polysaccharide derivatives (e.g., guar gum, guar derivatives, cellulose gum, cellulose derivatives, starch, starch derivatives), homopolymers and copolymers of ethylene oxide having a molar mass equal to or greater than 10,000 g/mol, polyvinyl alcohols, homopolymers and copolymers of vinylpyrrolidone, homopolymers and copolymers of vinylcaprolactam, homopolymers and copolymers of polyvinyl methyl ether, and mixtures thereof. Many nonionic polymers have thickening properties and are sometimes referred to as “nonionic thickening polymers.” Nonionic thickening polymers can be useful in the compositions of the instant disclosure, for example, when a certain degree of thickening is desired. In some instance, guar gum and/or nonionic guar derivatives are particularly useful, for example, hydroxypropyl guar.

     Fatty compounds other than the fatty alcohols discussed above, may optionally be included in the hair treatment compositions of the instant disclosure. The term “fatty compound” is interchangeable with the term “fatty material.” As is well known in the art, fatty compounds are compounds that are not soluble (or only sparingly soluble in water; they are hydrophilic and can often be solubilized in organic solvents. They include materials such as oils, fats, waxes, hydrocarbons, fatty esters, fatty acids, etc. Non-limiting examples of useful fatty compounds include oils, waxes, alkanes (paraffins), fatty acids, fatty esters, triglyceride compounds, lanolin, hydrocarbons, derivatives thereof, and mixtures thereof.

     The hair treatment compositions of the instant disclosure are particularly useful as a rinse-off product, i.e., a product that is applied to the hair and temporarily allowed to remain on the hair, for example, massaged into the hair, and subsequently rinsed from the hair prior to styling the hair. Thus, the instant disclosure relates to methods for treating the hair with the hair treatment compositions. The methods include applying a hair treatment composition to the hair and subsequently rinsing the hair treatment composition from the hair. The hair treatment compositions may be used as a conditioner composition that is applied to the hair before or after shampooing the hair; or it can be used as a conditioner composition that used without shampooing the hair. 
     Typically, the hair treatment composition is applied to wet or damp hair, massaged into/throughout the hair, and subsequently rinsed from the hair before optionally drying and/or styling the hair. The hair treatment composition may be allowed to remain on the hair prior to rinsing for a period of time, for example, a period of time of about 10 seconds to about 10 minutes, prior to rinsing from the hair. The hair treatment composition may be allowed to remain on the hair prior to rinsing for a period of time of at least 5 minutes, for example, at least 5 minutes to about 15 minutes. 
     In certain embodiments, the hair treatment compositions of the instant disclosure may be used as a leave-on product, i.e., a product that is applied to the hair prior to and/or while styling the hair and remains on the hair after the hair is styled. The leave-on product can be applied to wet, damp, or dry hair after shampooing and optionally conditioning the hair. The leave-on product may also be applied to wet, damp, or dry hair independent of shampooing and/or conditioning. 
     In certain embodiments, the hair treatment compositions of the instant disclosure are particularly useful in conjunction with chemical hair treatments. For example, the hair treatment compositions can be applied to chemically treated hair as a rinse-off or leave-on product. Also, the hair treatment compositions can be used as a pre-treatment or post-treatment before of after chemically treating hair, i.e., before or after treating the hair with chemically reactive products such as oxidative hair coloring/lightening compositions and hair relaxer and/or straightening compositions. 
     The methods of treating hair, according to the procedures discussed above, are useful for conditioning the hair. The procedures are also useful in methods for improving natural look and feel of the hair, reducing hair frizz, improving hair smoothness, hair alignment, and/or hair shine. The methods also relates to increasing the hydrophobicity of the hair. 
     The hair treatment compositions disclosed herein may be provided in a kit. For example, one or more of the hair treatment compositions of the instant disclosure may be included in a kit that also include one or more additional hair treatment compositions, for example, one or more cleansing compositions, in particular, one or more shampoo compositions. Each of the one or more hair treatment compositions in the kit are separately contained. In some instances, the kits include one or more hair treatment compositions according to the instant disclosure and one or more shampoo compositions, wherein each of the one or more hair treatment compositions and the one or more shampoo compositions are separately contained.

     Stability 
     The hair treatment compositions are stable and homogenous. In other words, the hair treatment compositions do not visually phase separate or develop sedimentation, and do not form visibly observable particulates. As shown the Example below, the hair treatment composition remained stable throughout the entire testing period. For instance, the hair treatment composition remained stable for at least 1 week at room temperature; the hair treatment composition remained stable for at least 8 weeks at 4° C.; the hair treatment composition remained stable for at least 8 weeks at 45° C. Accordingly, the instant disclosure relates to hair treatment compositions that remain visually homogenous and free from visual phase separation and particulate formation for at least 1 week at room temperature. Furthermore, the instant disclosure relates to hair treatment compositions that remain visually homogenous and free from visual phase separation and particulate formation for at least 8 weeks at 4° C. The instant disclosure also relates to hair treatment compositions that remain visually homogenous and free from visual phase separation and particulate formation for at least 8 weeks at 45° C. 
     Methods 
     The instant disclosure relates to methods for treating hair. The methods include applying a hair treatment composition according to the instant disclosure to the hair and subsequently rinsing the hair treatment composition from the hair. The hair treatment compositions may be used, for example, as a conditioner composition or a conditioning mask that is applied to the hair before or after shampooing the hair; or it can be used as a conditioner composition that used without shampooing the hair. Typically, the hair treatment composition is applied to wet or damp hair, massaged into/throughout the hair, and subsequently rinsed from the hair before optionally drying and/or styling the hair. The hair treatment composition may be allowed to remain on the hair prior to rinsing for a period of time, for example, a period of time of about 10 seconds to about 10 minutes, prior to rinsing from the hair. The hair treatment composition may be allowed to remain on the hair for about 10 seconds to about 5 minutes, about 10 seconds to about 2 minutes, about 30 seconds to about 10 minutes, about 30 seconds to about 5 minutes, about 30 seconds to about 2 minutes, about 1 minute to about 10 minutes, about 1 minute to about 5 minutes, or about 1 minute to 2 abouts 2 minutes, including any combination, sub-combination, range, or sub-range thereof.

     Example 3 
     Stability Data 
     The compositions of Example 2 were subjected to stability studies. The stability of the compositions was visually accessed upon initial manufacture of the composition (T 0 ). The compositions were again evaluated after one week of freeze-thaw testing (1 W FT). The compositions were placed in a stability chamber and subjected to temperature fluctuation at 12-hour intervals. For 12 hours, the compositions were held at −10° C. For the next 12 hours, the compositions were held at 25° C. The cycle was repeated 7 times (for 1 week). The compositions were seperately evaluated after 8 weeks in storage at 4° C. (8 W 45° C.), and after 8 weeks in storage at 45° C. (8 W 4° C.). The results are presented in the table below.

     Example 4 
     Sensorial Data 
     The compositions of Example 2 that were at least initially stable were tested to determine their benefits to hair. Highly bleached Caucasian hair swatches (SA40, 2.7 g, 27 cm) were used in the testing. Equal amounts of each composition tested (about 1.2 grams) were applied to damp hair swatches, massaged into the hair, and allowed to remain on the hair for 5 minutes. After 5 minutes, the compositions were rinsed from the hair swatches with room temperature tap water. After removing excess water from the hair swatches, they hair swatches were washed with a standard basic shampoo. After washing, the swatches were initially towel dried and then completely dried using a blow dryer. Throughout this process expert evaluators tested the hair swatches for a variety of sensorial effects: wet smoothness, wet combing, dry smoothness, dry combing, dry strength, and dry alignment. Specifically, the evaluators assessed whether sensorial effects were better than the benchmark (Inventive Composition A), worse than the benchmark, or substantially identical to the benchmark. The results are presented in the table below.

     Inventive Composition A provided the most balanced performance on both wet and dry hair, i.e., it provided the best results across the spectrum of all attributes tested. All comparative compositions failed to provide a full spectrum of improvements. For example, Comparative Composition C 7  showed improvements in smoothness and dry combining, but resulted in significant reductions in dry strength and dry alignment. Inferiority with respect to dry alignment results in a perception of the hair being dry and weakened, which is unfavorable to consumers. The complete and balanced nature of the various attributes provided to hair by Inventive Composition A is significant and surprisingly superior to that provided by the comparative compositions. 
     Definitions 
     As used herein, the terms “comprising,” “having,” and “including” (or “comprise,” “have,” and “include”) are used in their open, non-limiting sense. The phrase “consisting essentially of” limits the scope of a claim to the specified materials or steps and those that do not materially affect the basic and novel characteristics of the claimed invention. 
     The terms “a,” “an,” and “the” are understood to encompass the plural as well as the singular. Thus, the term “a mixture thereof” is interchangeable with “mixtures thereof.” Throughout the disclosure, the term “a mixture thereof” is used, following a list of elements as shown in the following example where letters A-F represent the elements: “one or more elements selected from the group consisting of A, B, C, D, E, F, or mixtures thereof.” The term, “a mixture thereof” does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more elements chosen from A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.” 
     Likewise, the term “a salt thereof” also relates to “salts thereof.” Thus, where the disclosure refers to “an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or mixtures thereof,” it indicates that that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be 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 salts referred to throughout the disclosure may include salts having a counter-ion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is non-limiting. 
     The expression “one or more” means “at least one” and thus includes individual components as well as mixtures/combinations. 
     The term “plurality” means “more than one” or “two or more.” 
     Some of the various categories of components identified may overlap. In such cases where overlap may exist and the composition/product includes two overlapping components (or more than two overlapping components), an overlapping component does not represent more than one component. For example, a component such as a fatty ester may fall within a definition of a “fatty compound” and within a definition of an “emulsifier.” If a particular composition/product requires both a fatty compound component and an emulsifier component, a single fatty ester can serve as only a fatty compound or an (a single fatty ester cannot serve as both the fatty compound and the emulsifier). 
     All percentages, parts and ratios herein are based upon the total weight of the compositions of the present invention, unless otherwise indicated. 
     An “alkyl radical” is a linear or branched saturated hydrocarbon-based group, particularly C 1 -C 8 , more particularly C 1 -C 6 , preferably C 1 -C 4  such as methyl, ethyl, isopropyl and tert-butyl; 
     An “alkoxy radical” is a alkyl-oxy wherein alkyl is as described herein before; 
     An “alkenyl radical” is a linear or branched unsaturated hydrocarbon-based group, particularly C 2 -C 8 , more particularly C 2 -C 6 , preferably C 2 -C 4  such as ethylenyl, propylenyl; 
     An “alkylene radical” is a linear or branched divalent saturated C 1 -C 8 , in particular C 1 -C 6 , preferably C 1 -C 4  hydrocarbon-based group such as methylene, ethylene or propylene. 
     All ranges and values disclosed herein are inclusive and combinable. For examples, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value to derive a sub-range, etc. Furthermore, all ranges provided are meant to include every specific range within, and combination of sub-ranges between, the given ranges. Thus, a range from 1-5, includes specifically points 1, 2, 3, 4 and 5, as well as sub-ranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.; and points of 1, 2, 3, 4, and 5 includes ranges and sub-ranges of 1-5, 2-5, 3-5, 2-3, 2-4, 1-4, etc. 
     Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are understood to be modified by “about,” whether or not expressly stated. Additionally, all numbers are intended to represent exact figures as additional embodiments, whether or not modified by “about.” For example, “an amount of about 1%” includes an amount of exactly 1%. As a further example, “an amount of 1%” includes an amount of about 1%. The term “about” is generally understood to encompass a range of +/−10% from the stated number, and is intended to cover amounts of +/−1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, and 10%. 
     The term “surfactants” includes salts of the surfactants even if not explicitly stated. In other words, whenever the disclosure refers to a surfactant, it is intended that salts of the surfactant are also encompassed to the extent such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in every instance throughout the disclosure), for example, by using language such as “a salt thereof” or “salts thereof.” Sodium and potassium are common cations that form salts with surfactants. However, additional cations such as ammonium ions, or alkanolammonium ions such as monoethanolammonium or triethanolammonium ions, may also form salts of surfactants. 
     The term “substantially free” or “essentially free” as used herein means the specific material may be present in small amounts that do not materially affect the basic and novel characteristics of the claimed invention. For instance, there may be less than 2% by weight of a specific material added to a composition, based on the total weight of the compositions (provided that an amount of less than 2% by weight does not materially affect the basic and novel characteristics of the claimed invention). Similarly, the compositions may include less than 2 wt %, less than 1.5 wt %, less than 1 wt %, less than 0.5 wt %, less than 0.1 wt %, less than 0.05 wt %, or less than 0.01 wt %, or none of the specified material. The term “substantially free” or “essentially free” as used herein may also mean that the specific material is not added to the composition but may still be present in a raw material that is included in the composition. 
     Furthermore, all components that are positively set forth in the instant disclosure may be negatively excluded from the claims, e.g., a claimed composition may be “free,” “essentially free” (or “substantially free”) of one or more components that are positively set forth in the instant disclosure. 
     All publications and patent applications cited in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications or patent application incorporated herein by reference, the present disclosure controls.
