Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Patent Application No. 17/007,752, filed August 31, 2020, and French Patent Application Publication No. 2010605, filed October 16, 2020, which are incorporated herein by reference in their entireties.

The present disclosure relates to cosmetic compositions and kits thereof. Aspects of the present disclosure also relate to methods of making such cosmetic compositions and methods of using such cosmetic compositions.

Consumers desire new and improved compositions for treating, caring for and/or conditioning skin or keratinous materials such as hair. Hair and skin are exposed to inherent and exogenous influences such as environmental, mechanical, chemical, heat and aging.

For example, the action of external environmental factors such as light and bad weather, and also the action of heat, mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, permanent waving and/or de-curling, blow drying, ironing or even repeated washing can damage and weaken the hair fibre. Over time, the hair can become dry, coarse, brittle or dull, especially in vulnerable areas, which may ultimately result in split ends.

Thus, to overcome these shortcomings, it is common practice to resort to hair care products using compositions intended to condition the hair, imparting to it satisfactory cosmetic properties, in particular in terms of smoothness, shine, softness, malleability, lightness, natural feel and good unwinding properties. For example, hair care compositions such as hair conditioner and/or treatment compositions may be used before or after washing the hair with shampoo and/or before or after subjecting the hair to a chemical treatment in order to improve or restore to the hair its natural luster, shine and softness, or to improve the feel, appearance and manageability of the hair.

It is understood that different forms of hair care and skin care compositions can provide different benefits.

However, there is still a need to provide improved hair manageability, e.g. improved hair alignment, reduced unwanted volume (especially reduced frizz) and increased shine. There is also a need to develop cosmetic products that can simultaneously provide other benefits in addition to the care and conditioning benefits, e.g. styling, volumizing, shaping, curl definition (for curly or wavy hair), and restylability or reshaping (without the need to reapply the product).

Aspects of the present disclosure relate to cosmetic compositions and kits thereof. Further aspects of the present disclosure relate to methods of making such cosmetic compositions and methods of using such cosmetic compositions.

The cosmetic compositions disclosed herein advantageously provide increased durability and/or strength, perceptible visible shine, fiber alignment, reduced frizz, and/or increased hair manageability. Without being bound to any particular theory, the inventors believe that cosmetic compositions, particularly those containing certain deep eutectic solvent systems, may diffuse into hair and form an extensive network. The extensive network may reinforce and/or stabilize hair structure, ultimately reducing hair frizz associated with high humidity.

Furthermore, the cosmetic composition may be capable of self-association, typically through hydrogen bonding interactions, which may enable the cosmetic composition to reinforce and/or strengthen hair, particularly damaged hair. In some embodiments, the cosmetic composition restores damaged hair. The inventors have also surprisingly discovered that the cosmetic composition may increase the straightness of hair without the use of heat, for example, from an iron, hair dryer, etc.

Cosmetic compositions typically include (a) from about 0.1 to about 25% by weight of citric acid;
(b) about 0.2 to about 40% by weight of one or more urea compounds; and (c) about 20% by weight or more of water;
The weight ratio of (a) citric acid to (b) urea compound is less than or equal to 1, and all weight percentages are based on the total weight of the cosmetic composition.

The cosmetic composition may contain a certain amount of a deep eutectic solvent. Preferably, the amount of the deep eutectic solvent is 1% by weight or more. The deep eutectic solvent may contain (a) a urea compound and (b) citric acid.

Preferably, the urea compound is selected from dimethylurea, hydroxyethylurea, urea, and mixtures thereof. In some cases, the weight ratio of (a) citric acid to (b) urea compound is about 1:1 to 1:8. In further cases, the weight ratio of (a) citric acid to (b) urea compound is about 1:1 to 1:6.

In at least one embodiment, the cosmetic composition comprises about 2.5 to about 40% by weight of one or more urea compounds and about 1.5 to about 25% by weight of citric acid. In at least one other embodiment, the cosmetic composition comprises about 20 to about 40% by weight of one or more urea compounds and about 15 to about 25% by weight of citric acid.

The cosmetic composition may further comprise from about 0.1 to about 10% by weight of one or more cationic surfactants. The one or more cationic surfactants may be cetrimonium chloride, stear ... chloride), behentrimonium chloride, behentrimonium methosulfate, behenamidopropyl trimonium methosulfate, stearamidopropyl trimonium chloride, arachidotrimonium chloride, distearyldimonium chloride, dicetyldimonium chloride, tricetylmonium chloride, oleamidopropyl dimethylamine, linoleamidopropyl dimethylamine, stearamidopropyl dimethylamine, oleyl hydroxyethyl imidazoline, stearamidopropyl dimethylamine, behenamidopropyl dimethylamine, behenamidopropyl diethylamine, behenamidoethyl diethylamine, behenamidoethyl dimethylamine, arachidamidopropyl dimethylamine, arachidamidopropyl diethylamine, arachidamidoethyl diethylamine, arachidamidoethyl dimethylamine and mixtures thereof.

In some cases, the cosmetic composition comprises from about 0.1 to about 25% by weight of one or more fatty compounds. The fatty compounds may be selected from fatty alcohols, fatty acid esters, fatty ethers, fatty acids, waxes, oils, derivatives thereof, and mixtures thereof.

Additionally or alternatively, the cosmetic composition may comprise from about 20 to about 95% by weight 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.

The cosmetic composition may comprise from about 0.1 to about 20% by weight of a thickening agent. The thickening agent may be selected from polyacrylate crosspolymers or crosslinked polyacrylate polymers, cationic acrylate copolymers, anionic acrylic or carboxylic acid polymers, polyacrylamide polymers, polysaccharides, gums, polyquaterniums, vinylpyrrolidone homopolymers/copolymers, C8-24 hydroxyl substituted fatty acids, C8-24 conjugated fatty acids, sugar fatty acid esters, polyglyceryl esters, and mixtures thereof.

Aspects of the present disclosure relate to a method of making a cosmetic composition. The method of making a cosmetic composition typically comprises:
(I)
Producing a deep eutectic solvent system comprising: (a) about 0.1 to about 25 wt. % citric acid; and (b) about 0.2 to about 40 wt. % of one or more urea compounds selected from dimethylurea, hydroxylethylurea, or a combination thereof, wherein the weight ratio of (a) citric acid to (b) urea compound(s) is 1 or less;
(II) adding the deep eutectic solvent system of (I) to the base composition to produce a cosmetic composition.

The method may further include mixing (a) the citric acid and (b) the urea compound, and, optionally, heating (a) the citric acid and (b) the urea compound to a temperature of about 70°C to about 90°C.

Aspects of the present disclosure relate to cosmetic compositions and kits thereof. Further aspects of the present disclosure relate to methods of making such cosmetic compositions and methods of using such cosmetic compositions. The cosmetic compositions disclosed herein advantageously provide increased durability and/or strength, perceptible visible shine, fiber alignment, reduced frizz and/or increased hair manageability.

The inventors have surprisingly discovered that certain ratios of compounds allow cosmetic compositions to provide improved durability and strength in combination with reduced hair frizz. Without being bound to any particular theory, the inventors believe that cosmetic compositions, particularly cosmetic compositions containing certain deep eutectic solvent (DES) systems, may diffuse into hair and form an extensive network. The extensive network may reinforce and/or stabilize the hair structure, ultimately reducing hair frizz associated with high humidity.

Cosmetic compositions, and/or ingredients thereof, may typically have the ability to self-associate through non-covalent interactions (i.e., hydrogen bonding, ionic and van der Waals interactions), thereby allowing the cosmetic composition to reinforce and/or strengthen hair, particularly damaged hair. In some embodiments, the cosmetic composition restores damaged hair. Furthermore, the inventors have surprisingly discovered that such cosmetic compositions may increase the straightness/alignment of hair fibers without the use of heat, e.g., from irons, hair dryers, etc. Cosmetic compositions such as those containing DES systems have also shown evidence of the shine benefits currently being investigated.

Cosmetic compositions according to the disclosed embodiments typically include
(a) about 0.1 to about 25 weight percent citric acid;
(b) about 0.2 to about 40% by weight of one or more urea compounds; and (c) about 20% by weight or more of water;
The weight ratio of (a) citric acid to (b) urea compound is less than or equal to 1, and all weight percentages are based on the total weight of the cosmetic composition.

The cosmetic composition may include an amount of a deep eutectic solvent system ("DES"). In some cases, the amount of deep eutectic solvent is about 1 wt% or more, preferably about 2 wt% or more, about 3 wt% or more, about 4 wt% or more, about 5 wt% or more, about 6 wt% or more, about 7 wt% or more, about 8 wt% or more, about 9 wt% or more, about 10 wt% or more, about 12 wt% or more, about 14 wt% or more, about 16 wt% or more, about 18 wt% or more, about 20 wt% or more, about 22 wt% or more, about 24 wt% or more, about 26 wt% or more, about 28 wt% or more, about 30 wt% or more, about 32 wt% or more, about 34 wt% or more, about 36 wt% or more, about 40 wt% or more, about 45 wt% or more, about 50 wt% or more, or about 60 wt% or more, based on the total weight of the cosmetic composition.

Method(s) of Producing a Cosmetic Composition
The disclosed embodiments relate to a method for producing a cosmetic composition. The method for producing a cosmetic composition typically comprises:
Producing a deep eutectic solvent system comprising: (a) about 0.1 to about 25 wt. % citric acid; and (b) about 0.2 to about 40 wt. % of one or more urea compounds selected from dimethylurea, hydroxylethylurea, or a combination thereof, wherein the weight ratio of (a) citric acid to (b) urea compound(s) is 1 or less;
(II) adding the deep eutectic solvent system of (I) to the base composition to produce a cosmetic composition.

The method may further include forming a deep eutectic solvent (DES) system of (I) by mixing citric acid and urea compound(s), for example in a ratio as discussed herein. In some cases, the DES system may be formed at room temperature, for example, when the citric acid and urea compound are mixed as liquids at room temperature. In other cases, the method also includes heating the mixture/combination of the citric acid and urea compound to a temperature of about 70° C. to about 90° C. Heating the mixture/combination of the citric acid and urea compound is usually beneficial when the citric acid and urea compound are not mixed as liquids at room temperature. The mixture/combination of the citric acid and urea compound may be heated to a temperature such that the citric acid and urea compound are mixed as liquids. For example, the mixture/combination of citric acid and urea compounds may 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 subrange thereof.

The method may include generating a cosmetic composition base by combining one or more ingredients, such as fatty compounds, polyols, thickeners, water-soluble solvents, silicone oils, etc. One of ordinary skill in the art will understand how to combine the aforementioned ingredients and/or compounds such that the composition base is stable and/or homogenous. In some cases, the cosmetic composition base may be heated, mixed, and/or subjected to shear forces, such as from an emulsifier.

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

Methods of treating and/or cleansing hair in accordance with the present disclosure may vary, but typically include applying a cosmetic composition disclosed herein, allowing the cosmetic composition to remain on the hair for a sufficient length of time, and rinsing the cosmetic composition from the hair.

In some instances, however, the cosmetic composition may be a no-rinse composition. For example, the cosmetic composition may be allowed to remain on the hair indefinitely, i.e., the cosmetic composition does not have to be removed or rinsed from the hair prior to styling.

The cosmetic composition may be applied to the hair in a sequence with other compositions. For example, the cosmetic composition may be applied to the hair before shampooing the hair, after shampooing the hair, before conditioning the hair, and/or after conditioning the hair, etc. However, it is not necessary that the cosmetic compositions be used in a certain sequence.

The cosmetic composition is useful for improving hair conditioning, handling, durability and/or improving the heat aging resistance of hair. The cosmetic composition can be applied to wet or damp hair and the hair may be massaged and spread throughout the hair, for example, using the hands and/or using a comb or brush. This results in smoothing and softening of the hair, reducing frizz, dryness and unwanted volume. Alternatively, the cosmetic composition and exogenous water may be combined, optionally mixed, and then applied to the body. For example, the cosmetic composition may be combined in a container, bowl, packaging, bottle, etc., and then applied to the body after the formation of an opaque emulsion.

In some cases, the cosmetic composition is used during a separate regular shower/bath routine, for example in combination with additional hair care compositions of the routine. The cosmetic composition may be applied to the hair individually or may be combined with one or more additional compositions. For example, the cosmetic composition may be mixed with a shampoo (or conditioner) before application to the hair. In this case, a mixture of shampoo (or conditioner) and cosmetic composition is simultaneously applied to the hair and simultaneously rinsed from the hair during the cleaning or conditioning process. Alternatively, the cosmetic composition may be layered on top of (or into) lathered hair to which shampoo (or conditioner) has already been applied, or vice versa. In this case, the cosmetic composition may be applied to the hair without rinsing it from the hair, and then the shampoo (or conditioner) is subsequently applied to the hair. Alternatively, the shampoo (or conditioner) may be applied to the hair first, without rinsing the shampoo (or conditioner) from the hair, and the cosmetic composition is also applied to the hair.

When used in combination with a shampoo and/or conditioner, the cosmetic composition may 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 (e.g., cosmetic composition of the present disclosure: shampoo/conditioner).

If the cosmetic composition is not mixed with another composition prior to application to the hair, the cosmetic composition may be applied to the hair immediately after or immediately after the hair is treated with another composition (e.g., shampoo and/or conditioner). For example, the cosmetic composition may be applied to the hair within a few seconds or 1, 2, 5, 10 or 20 minutes before or after shampoo and/or conditioner are applied to the hair.

The term "INCI" is an abbreviation for International Nomenclature of Cosmetic Ingredients, a system of names provided by the International Nomenclature Committee of the Personal Care Products Council to describe personal care ingredients.

As used herein, all ranges provided are meant to include all combinations of subranges within the specified ranges and between the given ranges. 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 ingredients and elements affirmatively described in this disclosure may be negatively excluded from the claims. In other words, the hair cleansing compositions of the present disclosure may be free of, or essentially free of, all ingredients and elements affirmatively described throughout this disclosure. In some instances, the hair cleansing compositions of the present disclosure are substantially free of a non-incidental amount of an ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound that is added alone to the hair cleansing composition. For example, the hair cleansing composition may be substantially free of a non-incidental amount of an ingredient or compound, but such ingredient(s) or compound(s) may be present as part of a raw material that is included as a blend of two or more compounds.

Some of the various categories of ingredients identified may overlap. In such cases where overlap exists and a hair cleansing composition includes both ingredients (or the composition includes two or more overlapping ingredients), the overlapping compounds do not represent more than one ingredient. For example, a compound may be characterized as both an emulsifier and a surfactant. If a particular hair composition includes both an emulsifier and a surfactant, a compound that can be characterized as both an emulsifier and a surfactant will only serve as either an emulsifier or a surfactant, but not both.

All publications and patent applications cited in this specification are incorporated herein by reference 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. In the event of a conflict between the present disclosure incorporated herein and a publication or patent application by reference, the present disclosure controls.

As used herein, the terms "comprising," "having," and "including" are used in their open, non-limiting sense. The terms "a" and "the" are understood to include the plural as well as the singular. Thus, the term "a mixture thereof" also relates to "mixtures thereof." Throughout this disclosure, the term "mixtures thereof" is used according to a list of elements as shown in the following example, where the 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 (but may include all of A, B, C, D, E, and F). Rather, it indicates that it can include a mixture of 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 a mixture of any two or more of A, B, C, D, E, and F."

The term "one or more" means "at least one" and thus includes individual components as well as mixtures/combinations. Except in the examples or where otherwise indicated, all numbers expressing amounts of components and/or reaction conditions may be modified in all instances by the term "about," which means within ±5% of the indicated number.

The term "treatment" (and grammatical variations thereof) as used herein refers to the application of the composition of the present disclosure to the surface of a keratinous substrate, such as hair on the user's head and/or body.

As used herein, the term "substantially free" or "essentially free" means that the particular material added to the composition is less than about 2% by weight based on the total weight of the composition. However, the composition may contain less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or none at all of the specified material. All components described herein may be optionally included or excluded from the composition/method/kit. If excluded, the composition/method/kit may not include or may be essentially free of that component. For example, a particular composition may not include or may be essentially free of silicone.

(II) adding the deep eutectic solvent system of (I) to a base composition to produce a cosmetic composition.

Implementations of the present disclosure are provided by the following examples, which are not limiting in nature but serve to clarify aspects of the technology.

Example 1
Three exemplary cosmetic compositions (Exemplary Compositions A-C) were prepared from a deep eutectic solvent ("DES") system. The DES system was prepared by mixing citric acid and dimethylurea at a temperature of about 80° C. to about 85° C. The DES system was then soluble in distilled water. The formulations of Exemplary Compositions A-C are shown in Table 1.

Example 2
Exemplary compositions B and D were applied to hair swatches and evaluated in comparison to application of a conventional sulfate-based shampoo alone (control). Exemplary composition D had the same formulation as exemplary composition B, except that the DES system was not formed from citric acid and dimethylurea prior to preparing the cosmetic composition.

Caucasian natural brown wavy hair swatches (medium curl) were washed and rinsed using a conventional sulfate-based shampoo, followed by application of exemplary compositions B and D. Exemplary compositions B and D, each in an amount of 0.4 grams per gram of hair swatch, were massaged into each hair swatch for 1 minute, left on the hair swatch unrinsed for an additional minute, rinsed for 30 seconds, and then blow-dried for 2 minutes. The swatches were then evaluated using a rinse-off procedure to estimate the effect of exemplary compositions B and D. Controls were prepared following the procedure above, except that no cosmetic composition was applied to the hair swatches after the conventional sulfate-based shampoo.

Additional hair swatches were prepared by applying exemplary compositions B and D to the hair swatches in amounts of 0.15 grams of each composition per gram of hair swatch. Specifically, exemplary compositions B and D were massaged into each hair swatch for one minute, left on the hair swatch without rinsing for one minute, and then blow-dried for two minutes. These hair swatches were evaluated to estimate the effect of exemplary compositions B and D using the no-rinse procedure.

The frizz resistance or degree of frizz of each hair swatch was evaluated using imaging analysis. After blow drying, the hair swatches were placed in a humidity chamber at room temperature with 80% relative humidity and the frizz resistance of the hair swatches was evaluated after 1 hour, 2 hours, 4 hours, 8 hours, 12 hours, and 24 hours.

Figure 1 provides images of hair swatches treated with exemplary compositions B and D and the control using a rinse procedure. Figure 2 provides images of hair swatches treated with exemplary compositions B and D and the control using a no-rinse procedure. As seen in Figures 1 and 2, exemplary compositions B and D provided significantly better anti-frizz properties relative to the control hair swatch. Additionally, exemplary compositions B and D provided better hair volume control. As shown in Table 2, surprisingly, exemplary composition B provides better volume control than exemplary composition D and the control.

Example 3
Hair swatches treated with exemplary compositions A and C were evaluated and compared to hair swatches treated only with a conventional sulfate-based shampoo (control). The hair swatches were washed and rinsed with a conventional sulfate-based shampoo, and then exemplary compositions A and C were applied in an amount of 0.15 grams of composition per gram of hair swatch, respectively. The composition was massaged into each hair swatch for one minute, left on the hair swatch without rinsing for one minute, and then blow-dried for two minutes. Controls were prepared according to the above procedure, except that no cosmetic composition was applied to the hair swatches after the conventional sulfate-based shampoo.

Using a no-rinse procedure, these hair swatches were evaluated to assess the effectiveness of exemplary compositions A and C. The hair swatches were subjected to cyclic fatigue using a cyclic tester to determine the durability of the hair swatches. The cyclic tester simulates daily hair care by subjecting a set number of fibers to repeated cyclic tensile deformation until failure. Additionally, the hair swatches were evaluated using differential scanning calorimetry for thermal densities associated with the crosslink density of the amorphous matrix. Differential scanning calorimetry measures the thermal stability of the major morphological components of hair.

As can be seen in Figures 3 and 4, the hair swatches treated with exemplary composition C exhibited significantly better durability and denaturation temperature than the control hair swatches. The hair swatches treated with exemplary composition A also exhibited improved durability and denaturation temperature than the control hair swatches.

Example 4
Hair swatches treated with Exemplary Compositions A and E, and Comparative Compositions 1 and 2 were evaluated in comparison to hair swatches treated only with a conventional sulfate-based shampoo (control). Exemplary Composition E had the same formulation as Exemplary Composition A, except that the cosmetic composition was prepared without preparing the DES system from citric acid and dimethylurea. Table 3 provides the formulations for Comparative Compositions 1 and 2.

Each hair swatch was massaged with 0.4 grams of each of Exemplary Compositions A and E and Comparative Compositions 1 and 2 per gram of hair swatch for 1 minute, left on the hair swatch without rinsing for an additional minute, rinsed for 30 seconds, and then blow-dried for 2 minutes. The hair swatches were then evaluated to estimate the effect of Exemplary Compositions A and E and Comparative Compositions 1 and 2 using a rinse-off procedure. A control was prepared according to the above procedure, except that no cosmetic composition was applied to the hair swatch after the conventional sulfate-based shampoo.

Additional hair swatches were treated with Exemplary Composition A in an amount of 0.15 grams per gram of hair swatch. Each hair swatch was massaged with Exemplary Composition A for 1 minute, left on the hair swatch without rinsing for 1 minute, and then blow-dried for 2 minutes. Using the no-rinse procedure, the hair swatches were evaluated to estimate the effect of Exemplary Composition A.

Hair was then evaluated to estimate the effect of Exemplary Compositions A and E on thermal denaturation temperature (corresponding to crosslink density), hair durability, Young's modulus, and elongation at break, in comparison with the effect 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.

Hair treated with exemplary composition A using both rinse and no-rinse procedures exhibited significantly better durability as measured by break cycles, and better denaturation temperature. For example, hair treated with exemplary composition A exhibited approximately a 40% increase in durability compared to comparative compositions 1 and 2. Similarly, the break elongation and Young's modulus of hair treated with exemplary composition A were better than the break elongation of hair treated with comparative compositions 1 or 2. Figures 5-8 are graphs of the break cycles, denaturation temperature, Young's modulus, and break elongation of hair treated with exemplary compositions A and E compared to comparative compositions 1 and 2 and a control.
