Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Application No. 17 / 007,752, filed August 31, 2020, and French Patent Application No. 2010605, filed October 16, 2020, which are incorporated herein by reference in their entirety.

[0003] open field

[0004] This disclosure relates to cosmetic compositions and kits thereof. Aspects of this disclosure also relate to methods for preparing such cosmetic compositions and methods for using such cosmetic compositions.

[0005] background

[0006] Consumers need new and improved compositions to treat, care for, and / or condition keratinous substances such as skin or hair. Hair and skin are affected by internal and external factors such as environmental factors, mechanical factors, chemical factors, heat, and aging.

[0007] For example, external atmospheric factors, such as light and harsh weather, as well as heat, mechanical, or chemical treatments, such as brushing, combing, dyeing, bleaching, perming and / or styling, blow-drying, flatironing, and even repeated washing, can damage and weaken hair fibers. Over time, hair can become dry, rough, brittle, or dull, especially in vulnerable areas and even more so at the ends, leading to split ends.

[0008] Therefore, to overcome these drawbacks, the common practice is to resort to hair care products with compositions designed to condition the hair, giving it satisfactory cosmetic properties, particularly in terms of smoothness, shine, softness, manageability, lightness, naturalness, and good detangling properties. For example, hair care compositions, such as conditioners and / or treatment compositions, can be used before or after washing hair with shampoo and / or chemical treatments to improve or restore the hair's natural shine, luster, and softness, or to improve the hair's feel, appearance, and manageability.

[0009] It should be understood that different forms of hair and skin care compositions can provide different benefits.

[0010] However, there is still a need to provide improved hair condition, such as improving hair alignment, reducing unwanted volume (especially frizz), and adding shine. There is also a need to develop beauty products that can provide additional benefits beyond the care and conditioning benefits, such as styling, volumizing, shaping, curl setting (for curly or wavy hair), and restyling or reshaping (without requiring reapplication of products).

[0011] SUMMARY

[0012] Aspects of the present disclosure relate to cosmetic compositions and kits thereof. Other aspects of the present disclosure relate to methods of making and methods of using such cosmetic compositions.

[0013] The cosmetic compositions disclosed herein advantageously provide increased durability and / or strength, perceptible visual shine, fiber alignment, reduced frizz, and / or increased hair manageability. Without being limited by any particular theory, the inventors believe that the cosmetic compositions, and in particular the cosmetic compositions containing certain eutectic solvent systems, can diffuse into the hair and form a broad network. The broad network can enhance and / or stabilize the hair structure, which will ultimately reduce hair frizz associated with high humidity.

[0014] Furthermore, the cosmetic compositions can generally be able to self-associate through hydrogen bonding interactions, which can enable the cosmetic compositions to enhance and / or strengthen the hair, particularly damaged hair. In some embodiments, the cosmetic compositions repair damaged hair. The inventors have also surprisingly found that the cosmetic compositions can increase the straightness of the hair without the use of heat such as from an iron, a blow dryer, and the like.

[0015] The cosmetic compositions generally comprise:

[0016] (a) about 0.1 to about 25 weight percent of citric acid;

[0026] Additionally or alternatively, the cosmetic composition can comprise about 20 to about 95 wt.% of a polyol. Suitable polyols include ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, pentylene glycol, diethylene glycol, dipropylene glycol, 1,3-propanediol, glycerin, polyethylene glycol, or mixtures thereof.

[0027] The cosmetic composition can comprise about 0.1 to about 20 wt.% of a thickening agent. The thickening agent can be selected from polyacrylate crosspolymers or crosslinked polyacrylate polymers, cationic acrylate copolymers, anionic acrylic or anionic carboxylic acid polymers, polyacrylamide polymers, polysaccharides, gums, polyquatemary ammonium salts, vinylpyrrolidone homopolymers / copolymers, C8-24 hydroxy-substituted fatty acids, C8-24 conjugated fatty acids, sugar fatty esters, polyglycerol esters, and mixtures thereof.

Other aspects of the present disclosure relate to methods of making and methods of using such cosmetic compositions. The cosmetic compositions disclosed herein advantageously provide increased durability and / or strength, perceptible visual shine, fiber alignment, reduced curl, and / or increased hair manageability.

[0056] The inventors have surprisingly discovered that certain compounds in specific ratios are able to provide cosmetic compositions with improved durability and strength, while reducing hair curl. Without being bound by any particular theory, the inventors believe that the cosmetic compositions, and in particular cosmetic compositions containing certain deep eutectic solvent (DES) systems, are able to diffuse into the hair and form a broad network. The broad network is able to enhance and / or stabilize the hair structure, which will ultimately reduce hair curl associated with high humidity.

In some embodiments, the cosmetic composition repairs damaged hair. In addition, the present inventors have surprisingly found that such cosmetic compositions can increase the straightness / alignment of hair fibers without the use of heat such as from a curling iron, blow dryer, etc. Cosmetic compositions, such as those containing DES systems, have also shown evidence of shine benefits that are currently under investigation

[0062] (c) about 20 wt.% or more of water,

[0063] wherein all weight percentages are based on the total weight of the cosmetic composition.

[0064] The cosmetic composition can comprise an amount of a deep eutectic solvent system (“DES”).

[0346] Kit

[0347] Aspects of the present disclosure relate to kits comprising a cosmetic composition as discussed herein. In one embodiment, the cosmetic composition of the present disclosure is a hair cosmetic or hair treatment composition. For example, the kit can comprise at least one cosmetic composition according to the present disclosure, e.g., a hair cosmetic and / or hair treatment composition, and one or more additional compositions, e.g., a shampoo, a hair conditioner, etc. The various compositions are separately contained in the kit. In some cases, the kit contains one or more cosmetic compositions, e.g., a hair cosmetic and / or hair treatment composition according to the present disclosure, a shampoo, a hair conditioner, a hair mask, and / or other hair treatment product, all of which are separately housed.

[0348] The packaged cosmetic composition can be packaged in a variety of different containers, such as, for example, a ready-to-use container. Non-limiting examples of useful packages include tubes, jars, caps, unit-dose packages, and bottles, including squeezable tubes, bottles, and sprayable containers. The package can be configured such that it can be attached to a wall, such as a wall of a bathroom, including a wall of a shower or bathtub.

In some cases, the package is a tube, such as a tube or dual tube having two compartments, each forming a separate compartment. Each compartment can contain a different composition. For example, one tube or compartment can contain a cosmetic composition according to the present disclosure, and the other tube can contain a composition for use with the cosmetic composition, such as a shampoo, a conditioner, a multi-in-one shampoo / conditioner (i.e., a conditioning shampoo; also known as a “co-wash”), a hair mask, or other cosmetic product.

[0349] One or more methods of producing a cosmetic composition

[0350] Aspects of the present disclosure relate to methods for producing a cosmetic composition. The method of producing a cosmetic composition generally comprises:

[0351] (1) producing a deep eutectic solvent system comprising:

[0352] (a) about 0.1 to about 25 wt. % citric acid; and

[0353] (b) about 0.2 to about 40 wt. % one or more urea-based compounds selected from dimethyl urea, hydroxyethyl urea, or a combination thereof,

[0354] wherein the weight ratio of (a) citric acid to (b) urea-based compounds is 1 or less; and

[0355] (II) adding the deep eutectic solvent system of (I) to a base composition to make a cosmetic composition.

[0356] The method can further include forming a deep eutectic solvent (DES) system of (I) by mixing citric acid and one or more urea-based compounds in a ratio, e.g., as discussed herein. In some cases, the DES system can form at room temperature, e.g., when the citric acid and urea-based compounds are mixed as liquids at room temperature. In other cases, the method further includes heating the mixture / combination of citric acid and urea-based compounds to a temperature of about 70 °C to about 90 °C. Heating the mixture / combination of citric acid and urea-based compounds is generally beneficial when the citric acid and urea-based compounds do not mix as liquids at room temperature. The mixture / combination of citric acid and urea-based compounds can be heated to a temperature such that the citric acid and urea-based compounds mix as liquids. For example, the mixture / combination of citric acid and urea-based compounds can be heated to a temperature of about 75 °C to about 90 °C, about 80 °C to about 90 °C, about 85 °C to about 90 °C, about 70 °C to about 85 °C, about 75 °C to about 85 °C, about 80 °C to about 85 °C, about 70 °C to about 80 °C, about 75 °C to about 80 °C, or about 70 °C to about 75 °C, or any range or sub-range thereof.

[0357] The method can include producing a base of the cosmetic composition by combining one or more components, e.g., a fatty compound, a polyol, a thickening agent, a water soluble solvent, a silicone oil, etc. The ordinarily skilled artisan will understand how to combine the foregoing components and / or compounds such that the base of the composition is stable and / or uniform. In some cases, the base of the cosmetic composition can be heated, mixed, and / or subjected to shear, e.g., shear from an emulsifier.

[0358] One or more methods of treating hair

[0359] Aspects of the present disclosure also relate to methods of using such cosmetic compositions. Methods of treating hair according to aspects of the present disclosure generally include:

[0360] (I) optionally, applying a shampoo to the hair;

[0361] (I1) optionally, rinsing the hair to remove at least a portion of the shampoo;

[0362] (III) applying a cosmetic composition comprising:

[0363] (a) about 0.1 to about 25 wt.% citric acid; and

[0364] (b) about 0.2 to about 40 wt.% of one or more urea-based compounds selected from dimethyl urea, hydroxyethyl urea, or combinations thereof,

[0365] wherein the molar ratio of (a) citric acid to (b) urea-based compounds is 1 or less; and

[0366] (IV) optionally, rinsing the hair to remove at least a portion of the cosmetic composition.

[0367] The method for treating and / or cleansing hair according to the present disclosure can vary, but generally includes applying a cosmetic composition as disclosed herein, allowing the cosmetic composition to remain on the hair for a sufficient amount of time, and rinsing the cosmetic composition from the hair.

[0368] However, in some cases, the cosmetic composition can be a leave-on composition. For example, the cosmetic composition can be allowed to remain on the hair indefinitely, i.e., without removing or rinsing the cosmetic composition from the hair prior to styling the hair.

[0369] The cosmetic composition can be applied to the hair in a certain order with other compositions. For example, the cosmetic composition can be applied to the hair before shampooing, after shampooing, before conditioning the hair, and / or after conditioning the hair, etc. However, the cosmetic composition is not required to be used in a certain order.

[0370] The cosmetic composition can be used to condition, style the hair, improve durability, and / or improve the hair's resistance to heat degradation. The cosmetic composition can be applied to wet or damp hair and can be massaged into the hair, e.g., with the hands, and / or applied all over the hair with a comb or brush. This results in smooth and soft hair that reduces frizz, dryness, and excess volume. Alternatively, the cosmetic composition and extraneous water can be combined and optionally mixed prior to application to the body. For example, the cosmetic composition can be combined in a container, bowl, package, bottle, etc., and subsequently applied to the body after forming an opaque emulsion.

[0371] In some cases, the cosmetic composition is used in conjunction with another hair care composition during a daily routine, e.g., during a person's normal shower / bathing routine. The cosmetic composition can be applied to the hair alone or can be combined with one or more additional compositions. For example, the cosmetic composition can be mixed with a shampoo (or conditioner) prior to application to the hair. In this case, the mixture of the shampoo (or conditioner) and the cosmetic composition are applied to the hair simultaneously during the cleansing or conditioning process and rinsed from the hair simultaneously. Alternatively, the cosmetic composition can be layered on (or foamed over) the hair to which the shampoo (or conditioner) has already been applied, or vice versa. In this case, the cosmetic composition can be applied to the hair and not rinsed from the hair, and then the shampoo (or conditioner) is applied to the hair. Alternatively, the shampoo (or conditioner) can be applied to the hair first and not rinsed from the hair, and the cosmetic composition is also applied to the hair.

[0372] When used in conjunction with a shampoo and / or a conditioner, the cosmetic composition can be mixed or used with the shampoo and / or conditioner in a ratio of about 1 : 10 to about 10: 1, about 1 :5 to about 5: 1, about 1 :3 to about 3: 1, about 1 :2 to about 2: 1, about 1 : 1 to about 4: 1, about 1 : 1 to about 3: 1, or about 1 : 1 to about 2: 1 (cosmetic composition of the present disclosure: shampoo / conditioner, etc.).

[0373] When the cosmetic composition is not mixed with another composition prior to application to the hair, the cosmetic composition can be applied to the hair immediately after or before the hair is treated with another composition, such as a shampoo and / or a conditioner. For example, the cosmetic composition can be applied to the hair within about a few seconds or 1, 2, 5, 10, or 20 minutes before or after the shampoo and / or conditioner is applied to the hair.

[0374] The term "INCI" is an abbreviation for International Nomenclature of Cosmetic Ingredients, which is a naming system for personal care ingredients provided by the International Nomenclature Committee of the Personal Care Products Council.

[0375] As used herein, all ranges provided are intended to include every specific range and combination of sub-ranges within the given range. Thus, a range of 1-5 specifically includes 1, 2, 3, 4, and 5, as well as sub-ranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.

[0376] All components and elements expressly recited in the present disclosure can be excluded from the claims. In other words, the hair cleansing compositions (nanoemulsions) of the present disclosure can be free or substantially free of all components and elements expressly recited throughout the present disclosure. In some cases, the cosmetic compositions of the present disclosure can be substantially free of an incidental amount of one or more ingredients or compounds described herein. An incidental amount of an ingredient or compound is the amount of the ingredient or compound that is added to the hair cleansing composition in its own right. For example, a hair cleansing composition can be substantially free of an incidental amount of an ingredient or compound, although such ingredient or compound(s) can be present as part of a raw material included as a blend of two or more compounds.

[0377] It is recognized that some of the various class components can overlap. In cases where overlap can exist and the hair cleansing composition includes both components (or the composition includes more than two components overlap), the overlapping compound does not represent more than one component. For example, certain compounds can be characterized as both an emulsifier and a surfactant. If a particular hair composition includes both an emulsifier and a surfactant, the compound that is characterized as both an emulsifier and a surfactant will act as only an emulsifier or a surfactant, not both.

[0378] All publications and patent applications cited in this specification are herein incorporated by reference and for any and all purposes to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference and herein. In the event of a conflict between the present disclosure and any publication or patent application incorporated herein by reference, the present disclosure controls.

[0379] As used herein, the terms "comprising," "having," and "including" are used in their open, non-limiting sense. The terms "one," "a," and "the" are understood to encompass the plural as well as the singular. Thus, the term "mixtures thereof" also refers to "mixtures thereof." Throughout the disclosure, the term "mixtures thereof" is used following a recitation of elements as shown in the following example, where letters A-F represent elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, and mixtures thereof." The term "mixtures thereof" does not require that the mixture include all of A, B, C, D, E, and F (although it can include all of A, B, C, D, E, and F). Rather, it indicates that a mixture can include any two or more of A, B, C, D, E, and F. In other words, it is equivalent to the phrase "one or more elements selected from the group consisting of A, B, C, D, E, F, and mixtures of any two or more of A, B, C, D, E, and F."

[0380] The expression "one or more" means "at least one" and thus includes individual components as well as mixtures / combinations. Except in operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions are to be understood as modified in all instances by the term "about," meaning ±5% of the indicated number.

[0381] The term "treating" (and grammatical variations thereof) as used herein means applying a composition of the present disclosure to the surface of a keratinous substrate, such as the hair on the head and / or body of a user.

[0382] The term "substantially free" as used herein means that the specified material is added to the composition in an amount of less than about 2% by weight based on the total weight of the composition. However, the composition can include less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or be completely free of the specified material. All components listed herein can optionally be included in or excluded from the composition / method / kit. When excluded, the composition / method / kit can be free or substantially free of the component. For example, a particular composition can be free or substantially free of silicone.

[0410] Embodiments of the present disclosure are provided by the following examples. The following examples are intended to illustrate aspects of the technology and do not constitute a limitation in nature.

[0411] Example 1

[0412] Three exemplary cosmetic compositions (Exemplary Compositions A-C) were produced from a deep eutectic solvent (“DES”) system. The DES system was produced by mixing citric acid and dimethyl urea to a temperature of about 80 °C to about 85 °C. The DES system was then dissolved in distilled water. The formulations of Exemplary Compositions A-C are provided in Table 1 below.

[0413] Table 1

[0414]

[0415] Example 2

[0416] Exemplary Compositions B and D were applied to hair samples and evaluated in comparison to application of a traditional sulfate-based shampoo alone (control). Exemplary Composition D had the same formulation as Exemplary Composition B except that a DES system was not formed from citric acid and dimethyl urea prior to producing the cosmetic composition.

[0417] Prior to the application of exemplary compositions B and D, a natural brown wavy Caucasian hair sample (medium curl) was washed and rinsed with a conventional sulfate-based shampoo. An amount of 0.4 grams of each exemplary composition B and D per gram of hair sample was massaged onto its respective hair sample for one minute, left on the hair sample for an additional one minute, rinsed off for 30 seconds, and then blown dry for two minutes. These hair samples were then evaluated using the rinse-off procedure to assess the effects of exemplary compositions B and D. A control was prepared according to the procedure described above, except that no cosmetic composition was applied to the hair sample after the conventional sulfate-based shampoo.

[0418] Additional hair samples were prepared by applying exemplary compositions B and D to the hair samples (in an amount of 0.15 grams of the composition per gram of the respective hair sample). Specifically, exemplary compositions B and D were massaged onto their respective hair samples for one minute, left on the hair samples for one minute, and then followed by drying for two minutes. These hair samples were evaluated using the retention procedure to assess the effects of exemplary compositions B and D.

[0419] Each hair sample was evaluated for anti-curl properties or degree of curl using imaging analysis. The anti-curl properties of the hair samples were evaluated after the hair samples were blown dry, and after the hair samples were in a humidity chamber at 80% relative humidity and room temperature for 1 hour, 2 hours, 4 hours, 8 hours, 12 hours, and 24 hours.

[0420] Figure 1 Images of the hair samples treated with exemplary compositions B and D, and the control using the rinse-off procedure, are provided. Figure 2 Images of the hair samples treated with exemplary compositions B and D, and the control using the retention procedure, are provided. As shown in Figure 1 and 2 Exemplary compositions B and D provided significantly better anti-curl properties to the control hair sample. In addition, exemplary compositions B and D provided better hair volume control. Exemplary composition B provided better frizz control than exemplary composition D and the control, as shown in Table 2.

[0423] Example 3

[0424] Hair samples treated with exemplary compositions A and C were evaluated and compared to hair samples treated with only a conventional sulfate-based shampoo (control). The hair samples were washed with a conventional sulfate-based shampoo and rinsed prior to application of exemplary compositions A and C (in an amount of 0.15 grams of the composition per gram of the respective hair sample). The compositions were massaged onto their respective hair samples for one minute, left on the hair samples for one minute, and then followed by a two minute dry down. The control was prepared according to the procedure described above, except that no cosmetic composition was applied to the hair sample after the conventional sulfate-based shampoo.

[0425] The hair samples were evaluated using a retention procedure to assess the effectiveness of exemplary compositions A and C. The hair samples were subjected to cyclic fatigue using a cyclic tester to determine the durability of the hair samples. The cyclic tester simulates daily hair grooming by subjecting a number of fibers to repeated cyclic tensile deformations until failure. In addition, the hair samples were also evaluated for thermal denaturation temperature using differential scanning calorimetry, which is related to the crosslink density of the amorphous matrix. Differential scanning calorimetry measures the thermal stability of the major morphological components of hair.

[0426] As shown in Tables 1 and 2, the hair samples treated with exemplary compositions C exhibited significantly better durability and denaturation temperature than the control hair samples. The hair samples treated with exemplary composition A also exhibited improved durability and denaturation temperature than the control hair samples. Figure 3 4 As shown in Tables 1 and 2, the hair samples treated with exemplary compositions C exhibited significantly better durability and denaturation temperature than the control hair samples. The hair samples treated with exemplary composition A also exhibited improved durability and denaturation temperature than the control hair samples.

[0427] Example 4

[0428] Hair samples treated with exemplary compositions A and E and comparative compositions 1 and 2 were evaluated in comparison to hair samples treated with only a conventional sulfate-based shampoo (control). Exemplary composition E has the same formulation as exemplary composition A, except that the DES system is not prepared from citric acid and dimethyl urea prior to preparing the cosmetic composition. The formulations of comparative compositions 1 and 2 are provided in Table 3.

[0429] Table 3

[0430]

[0431] An amount of 0.4 grams of each of exemplary compositions A and E and comparative compositions 1 and 2 were massaged onto their respective hair samples for one minute, left on the hair samples for one minute, rinsed for 30 seconds, and then blow dried for two minutes. The hair samples were then evaluated using a rinse-out procedure to assess the effectiveness of exemplary compositions A and E and comparative compositions 1 and 2. The control was prepared according to the procedure described above, except that no cosmetic composition was applied to the hair sample after the conventional sulfate-based shampoo. ​

[0432] Additional hair samples were treated with an amount of 0.15 grams of exemplary composition A per gram of hair sample. Exemplary composition A was massaged onto each hair sample for one minute, left on the hair sample for one minute, and then followed by two minutes of drying. The hair samples were evaluated using the retention procedure to assess the effect of exemplary composition A.

[0433] The hair was then evaluated to assess the effect of exemplary compositions A and E on the thermal denaturation temperature (which corresponds to crosslink density), durability of the hair, Young's modulus, and elongation at break, compared to the effects of comparative compositions 1 and 2 and the control. The thermal denaturation temperature and durability of the hair were determined as discussed in Example 2.

[0434] Hair treated with the rinse and retention procedure with exemplary composition A exhibited significantly better durability, as measured by the number of break cycles, and better denaturation temperature. For example, hair treated with exemplary composition A exhibited about a 40% increase in durability compared to comparative compositions 1 and 2. Similarly, the elongation at break and Young's modulus of hair treated with exemplary composition A were superior to the elongation at break of hair treated with comparative compositions 1 or 2. Figures 5-8 is a graph of the number of break cycles, denaturation temperature, Young's modulus, and elongation at break of hair treated with exemplary compositions A and E compared to comparative compositions 1 and 2 and the control.
