Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Patent Application No. 17 / 007,832, filed August 31, 2020, and French Patent Application Publication No. 2010608, filed October 16, 2020, which are incorporated herein by reference in their entireties.

[0002] 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. [Background technology]

[0003] Consumers desire new and improved compositions for treating, caring for and / or conditioning skin or keratinous materials such as hair, which are exposed to inherent and exogenous influences such as environmental, mechanical, chemical, heat and aging factors.

[0004] 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 fiber. Over time, the hair can become dry, coarse, brittle or dull, especially in vulnerable areas, which can eventually result in split ends.

[0005] Thus, to overcome these drawbacks, it is common practice to resort to hair care products using compositions intended to condition the hair, endowing it with satisfactory cosmetic properties, especially in terms of smoothness, shine, softness, manageability, lightness, natural feel, and good unwinding properties. For example, hair care compositions such as hair conditioners and / or treatment compositions may be used before or after shampooing the hair and / or before or after chemically treating the hair, 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.

[0006] It is understood that different forms of hair care and skin care compositions can provide different benefits.

[0007] However, there is still a need to provide improved hair manageability, such as 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 care and conditioning benefits, such as styling, volumizing, shaping, curl definition (for curly or wavy hair), and restylability or reshaping (without the need to reapply the product). Summary of the Invention

[0008] 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 on keratinous substrates such as hair and skin.

[0009] When the keratin substrate is hair, particularly human scalp hair, the cosmetic composition of the present disclosure simultaneously achieves both surface and deep repair for the hair. The inventors have surprisingly discovered that certain compounds and their combination in a specific weight and / or molar ratio enable the cosmetic composition to significantly improve the durability and resistance of hair to thermal degradation. Furthermore, the inventors have recognized that forming a deep eutectic solvent system ("DES") from certain compounds and their combination in a specific weight and / or molar ratio before forming the cosmetic composition enhances the benefits achieved by the cosmetic composition, for example, by forming the DES system before incorporating it into a base composition containing the cosmetic composition.

[0010] Furthermore, the cosmetic composition may be formulated to form a lamellar phase when the cosmetic composition is mixed with exogenous water. Without being bound by any particular theory, it is believed that the lamellar structure formed by the cosmetic composition further enhances the benefits achieved by the cosmetic composition, particularly improving hair manageability and / or reducing frizz.

DETAILED DESCRIPTION OF THE INVENTION

[0022] It should be understood that the various aspects are not limited to the arrangements and instrumentality shown in the drawings.

[0023] 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 on keratinous substrates such as hair and skin.

[0024] When the keratin substrate is hair, particularly human scalp hair, the cosmetic composition of the present disclosure simultaneously achieves both surface and deep repair of the hair. The inventors have surprisingly discovered that certain compounds and their combination in a specific weight and / or molar ratio enable the cosmetic composition to significantly improve the durability and resistance of hair to thermal degradation. Furthermore, the inventors have recognized that forming a deep eutectic solvent system ("DES") from certain compounds and their combination in a specific weight and / or molar ratio before forming the cosmetic composition enhances the benefits achieved by the cosmetic composition, for example, by forming the DES system before incorporating it into a base composition containing the cosmetic composition.

[0025] Additionally, 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.

[0026] The cosmetic compositions disclosed herein may also advantageously reduce frizz and / or increase hair manageability when applied to hair. Without being bound by any particular theory, the inventors believe that cosmetic compositions, particularly those containing certain deep eutectic solvent systems, may disrupt weak bonds in hair associated with a moist atmosphere, thereby reducing frizz and increasing hair manageability.

[0027] The cosmetic composition may be formulated to form a lamellar phase when the cosmetic composition is mixed with exogenous water. Without being bound by any particular theory, it is believed that the lamellar structure formed by the cosmetic composition further enhances the benefits achieved by the cosmetic composition, particularly improving hair manageability and / or reducing frizz.

[0028] Cosmetic compositions can also provide unique sensory and consumer experiences. For example, cosmetic compositions can be activated by heat and / or shear, such that the composition experiences a sensory and / or tactile change. In some instances, the cosmetic composition transitions from behaving more solid-like to behaving more liquid-like in the presence of heat activation and / or shear, such as obtained by a user rubbing the cosmetic composition between their hands or using the cosmetic composition in a warm shower or bathtub. In some instances, the viscosity of the cosmetic composition can transition from a viscosity of about 10 to about 500 Pa*s at a temperature of 24°C to a reduced viscosity of less than 100 Pa*s at a temperature of 40°C after 90 seconds, as measured with a Brookfield DV2T viscometer using an LV 04 spindle at a range of 1 to 10 rpm.

[0029] Cosmetic compositions typically include: (a) about 20 to about 95 weight percent of a polyol; (b) from about 5 to about 70% by weight of one or more monoalcohols having 2 to 6 carbon atoms; (c) about 0.1 to about 10 wt. % of one or more cationic surfactants; (d) about 0.1 to about 20 wt. % of one or more aliphatic compounds; (e) about 1 to about 15 wt. % (i) citric acid, and (ii) Urea compounds A combination of Including, the weight ratio of polyol to monoalcohol(s) (polyol:monoalcohol(s)) is 20:1 to 1:20; The molar ratio of (i) citric acid to (ii) urea compound is from about 10:0.5 to about 0.5:10, and the weight percentages are based on the total weight of the cosmetic composition.

[0030] The cosmetic composition may be formulated to have a ratio of polyol to monoalcohol (i.e., total polyol:total monoalcohol) of 20:1 to 1:20. For example, the weight ratio of polyol to monoalcohol having 2 to 6 carbon atoms may be 20:1 to 1:20, 18:1 to 1:20, 15:1 to 1:20, 10:1 to 1:20, 7:1 to 1:20, 6:1 to 1:20, 5:1 to 1:20, 4:1 to 1.1:20, 20:1 to 1:18, 20:1 to 1:15, 20:1 to 1:10, 20:1 to 1:7, 20:1 to 1:6, 20:1 to 1:5, 20:1 to 1:4, including ranges and subranges therebetween (e.g., 5:1 to 1:5, 4:1 to 1:4, 5:1 to 1:1, etc.). In at least one embodiment, the cosmetic composition is formulated such that the total amount of polyols exceeds the total amount of monoalcohols. In at least another embodiment, the cosmetic composition is formulated such that the total amount of glycols exceeds the total amount of monoalcohols.

[0031] The cosmetic composition may be formulated to have a molar ratio of (i) citric acid to (ii) urea compound, which may be about 12:0.5 to about 0.5:12. In some examples, the cosmetic composition may be formulated to have a molar ratio of (i) citric acid to (ii) urea compound of about 11:1 to about 1:11, about 10:1 to about 1:10, about 9:1 to about 1:9, about 9:1 to about 1:1, about 9:1 to about 3:2, about 8:1 to about 0.5:10, about 7:1 to about 0.5:10, about 6:1 to about 0.5:10, about 5:1 to about 0.5:10, about 4:1 to about 0.5:10, about 3:1 to about 0.5:10; 10:1 to about 1:10, about 9:1 to about 1:10, about 8:1 to about 1:10, about 7:1 to about 1:10, about 8:1 to about 1:10, about 7:1 to about 1:11, about 9:1 to about 1:10, about 9:1 to about 1:10, about 8:1 to about 1:10, about 7:1 to about 1:11, about 11:1 to about 1:11, about 10 ... :1 to about 1:10, about 6:1 to about 1:10, about 5:1 to about 1:10, about 4:1 to about 1:10, about 3:1 to about 1:10; about 10:1 to about 2:10, about 9:1 to about 2:10, about 8:1 to about 2:10, about 7:1 to about 2:10, about 6:1 to about 2:10, about 5:1 to about 2:10, about 4:1 to about 2:10, about 3:1 to about 2:10; about 10:1 to about 2:8, about 9:1 to about 2:8, about 8:1 to about 2:8, about 7:1 to about 2:8, about 6:1 to about 2:8, about 5:1 to about 2:8, about 4:1 to about 2:8, about 3:1 to about 2:8; about 10:1 to about 2:6, about 9:1 to about 2:6, about 8:1 to about 2:6, about 7:1 to about 2:6, about 6:1 to about 2:6, about 5:1 to about 2:6, about 4:1 to about 2:6, about 3:2 to about 2:6; about 2:1 to about 2:10, about 1:1 to about 2:10, about 3:2 to about 2:9, about 3:2 to about 2:8, about 3:2 to about 2:7, about 3:2 to about 2:6, about 3:2 to about 2 The urea compound(s) may be formulated to have a weight ratio of citric acid to urea compound(s) of about 3:2 to about 2:4, about 5:1 to about 3:2, about 4:1 to about 3:2, about 3:2 to about 2:3, about 1:1 to about 1:4, about 1:1 to about 1:3, about 1:1 to about 1:2, or about 1:1.3 to about 1:1.6, including ranges and subranges therebetween (e.g., about 3:2 to about 2:5, about 2:1 to about 2:5, about 1:1 to about 2:5, about 1:1 to about 2:4, etc.).

[0032] In certain embodiments, the cosmetic composition may be formulated to have a weight ratio of (i) citric acid to (ii) urea compound of about 10:1, 9.5:1, 9:1, 8.5:1, 8:1, 7.5:1, 7:1, 6.5:1, 6:1, 5.5:1, 5:1, 4.5:1, 4:1, 3.5:1, 3:1, 3:2, 2:8:1, 1.4:1, 1.2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1.6, 1.7, 1.8, or 1.9.

[0033] The molar ratio of (i) citric acid to (ii) urea compound in the compositions of the present disclosure is from about 10:0.5 to about 0.5:10, including ranges and subranges therebetween. In embodiments, a deep eutectic solvent is formed when the molar ratio of (i) citric acid to (ii) urea compound is from about 10:0.5 to about 0.5:10, including ranges and subranges therebetween.

[0034] For example, the cosmetic composition may be formulated to have a molar ratio of (i) citric acid to (ii) the urea compound of about 10:0.5 to about 0.5:10.

[0036] The citric acid and urea, or a portion thereof, may form a deep eutectic solvent system ("DES") system prior to inclusion in the base composition of the cosmetic composition. The base composition of the cosmetic composition may be a composition of one or more components of the cosmetic composition. For example, in some instances, the base composition may contain all of the components of the cosmetic composition except for the citric acid and urea compound(s). After the DES system is incorporated into the base cosmetic composition, the cosmetic composition may at least partially comprise the DES system. Further description of the DES system and methods of making the DES system are disclosed herein.

[0037] During use, the user combines the cosmetic composition with extraneous water (e.g., water other than water already contained in the cosmetic composition). When the cosmetic composition is mixed with or comes into contact with extraneous water, the cosmetic composition may form a lamellar phase structure. "Lamellar phase structure" generally refers to the packing of head-polar, tail-nonpolar long-chain molecules in an environment of bulk polar liquid (i.e., water from the hair) as sheets of bilayers separated by the bulk liquid. In some cases, the cosmetic composition may form a mixed structure when combined with extraneous water. As used herein, the term "mixed structure" refers to a combination of lamellar phase and crystals. Additionally or alternatively, the cosmetic composition may form an opaque emulsion or a cloudy emulsion when combined with extraneous water.

[0038] In some instances, the cosmetic composition forms a lamellar phase structure, a mixed phase structure, and / or an opaque emulsion when exogenous water is combined with the cosmetic composition in a ratio (water:composition) ranging from 0.1:1 to 3:1, preferably 0.5:1, 1:1, 1.5:1, or 2:1. Additionally and / or alternatively, the formation of a lamellar phase structure, a mixed phase structure, and / or an opaque emulsion may occur by combining an amount of exogenous water such that the total amount of water in the cosmetic composition is increased to greater than 10 wt.%, 12 wt.% or more, 15 wt.% or more, 20 wt.% or more, 25 wt.% or more, or 30 wt.% or more, based on the total weight of the cosmetic composition prior to combination with the exogenous water, in some instances. In some embodiments, the opaque or cloudy emulsion has a viscosity that is the same as or greater than the viscosity of the composition prior to combination with the exogenous water.

[0039] When combined with external water, such as from a user's wet or damp hands, wet or damp skin, wet or damp hair, and / or a faucet, the cosmetic composition may form a lamellar phase structure, a mixed structure phase, and / or an opaque emulsion. For example, this may occur when a consumer applies the cosmetic composition to a wet or damp part of the body (e.g., hands, face, skin, hair, etc.). The user may then physically manipulate the applied cosmetic composition (e.g., by rubbing hands together or rubbing the composition against another part of the body, such as the face, hair, etc.). In some instances, the formation of the lamellar phase structure, the mixed structure phase, and / or the opaque emulsion occurs automatically, without the need for mixing. In other words, the cosmetic composition becomes sufficiently combined with external water by simply contacting the external water. However, in some instances, a minimal amount of mixing may be necessary or even encouraged.

[0040] The mixed structure formed from the combination of the cosmetic composition and extraneous water can occur without or in conjunction with active mixing from the user. For example, this can be readily achieved during use of the cosmetic composition by physically manipulating (e.g., mixing) the cosmetic composition with extraneous water, for example, using one's body (e.g., with one's hands).

[0041] The cosmetic composition is usually translucent or transparent before being combined with extraneous water.For example, the cosmetic composition may have a transmittance of at least 50% at a wavelength of 600 nm, as measured, for example, using a Lambda 40 UV-Visible spectrometer.In some embodiments, the composition may have a transmittance of at least 60%, at least 70%, at least 80%, at least 90%, or at least 95% at a wavelength of 600 nm, as measured, for example, using a Lambda 40 UV-Visible spectrometer.

[0042] Cosmetic compositions are typically stored at a temperature of 25°C for 1 s before being combined with exogenous water. -1For example, the cosmetic composition may have a viscosity of about 1 mPa.s or less at a shear rate of about 1 mPa.s at a temperature of 25°C, prior to combination with exogenous water, of about 1 mPa.s to about 1 Pa.s, about 1 mPa.s to about 800 mPa.s, about 1 mPa.s to about 600 mPa.s, about 1 mPa.s to about 500 mPa.s, about 1 mPa.s to about 400 mPa.s, or about 1 mPa.s to about 300 mPa.s; about 100 mPa.s to about 1 Pa.s, about 100 mPa.s to about 800 mPa.s, about 100 mPa.s to about 600 mPa.s, about 100 mPa.s to about 500 mPa.s, about 100 mPa.s to about 400 mPa, or about 100 mPa to about 300 mPa; about 300 mPa to about 1 Pa.s, about 300 mPa to about 800 mPa, about 300 mPa to about 600 mPa, or about 300 mPa to about 500 mPa; about 500 mPa to about 1 Pa.s, about 500 mPa to about 800 mPa, or about 500 mPa to about 600 mPa, including ranges and subranges therebetween. Viscosity measurements can be performed, for example, using a Brooksfield Viscometer, Model RVT (Brookfield Engineering Laboratories, Inc.) at about 60 revolutions per minute (RPM) at ambient room temperature of about 20-25°C; the spindle size may be selected in the range of disk spindle No. 1 to No. 4 according to the manufacturer's recommended standard procedures.

[0043] In some instances, the cosmetic composition is free of water or substantially free of water (anhydrous or substantially anhydrous). Alternatively or additionally, the cosmetic composition may have an amount of water that is less than 6 wt.%, preferably less than 5 wt.%, preferably less than 4 wt.%, preferably less than 3 wt.%, preferably less than 2 wt.%, preferably less than 1 wt.%, and / or less than 0.5 wt.%, based on the total weight of the cosmetic composition. In at least some embodiments, the cosmetic composition has substantially / essentially 0 wt.% or 0 wt.% water based on the total weight of the cosmetic composition.

[0044] Additionally or alternatively, the cosmetic composition may include arginine. In some cases, the arginine may be l-arginine, d-arginine, and / or a racemic mixture.

[0045] Suitable ingredients, such as those listed below, may be included or excluded from formulations for cosmetic compositions depending on the particular combination of other ingredients, the form of the cosmetic composition, and / or the use of the formulation (e.g., lotion, gel, cream, spray, etc.) The cosmetic composition may be formulated, for example, as a hair care composition and / or hair cosmetic composition and / or hair treatment composition and / or skin care composition and / or scalp care composition for use on hair and / or skin.

For example, one tube or compartment may contain a cosmetic composition according to the present disclosure, while the other tube may contain a cosmetic composition, such as a shampoo, conditioner, all-in-one shampoo / conditioner (i.e., conditioning shampoo; also referred to as a "co-wash"), mask, or other cosmetic product.

[0121] Method(s) of Producing a Cosmetic Composition Aspects of the disclosure relate to a method for producing a cosmetic composition, typically comprising: (I) (i) citric acid, and (ii) Urea compounds and producing a deep eutectic solvent system comprising: (i) citric acid and (ii) a urea compound in a molar ratio of about 10:0.5 to about 0.5:10; (II) (a) from about 20 to about 95 weight percent of a polyol, based on the weight of the base composition; (b) from about 5 to about 70 weight percent, based on the weight of the base composition, of one or more monoalcohols having 2 to 6 carbon atoms; (c) from about 0.1 to about 10 wt. % of one or more cationic surfactants, based on the weight of the base composition; and (d) about 0.1 to about 20% by weight of one or more aliphatic compounds, based on the weight of the base composition a base composition comprising: a polyol and a monoalcohol(s) in a weight ratio (polyol:monoalcohol(s)) of 20:1 to 1:20; and adding a deep eutectic solvent system (I) to the base composition. Includes:

[0122] The method may further include forming a (I) deep eutectic solvent (DES) system by mixing (i) citric acid and (ii) a urea compound in a ratio, for example, as discussed herein. In some cases, the DES system may be formed at room temperature, for example, when the citric acid and the urea compound are mixed as liquids at room temperature. In other cases, the method includes heating the mixture / combination of the citric acid and the urea compound to a temperature of about 70°C to about 90°C. Heating the mixture / combination of the citric acid and the urea compound is typically beneficial when the citric acid and the urea compound are not mixed as liquids at room temperature. The mixture / combination of the citric acid and the urea compound may be heated to a temperature such that the citric acid and the urea compound are mixed as liquids. For example, the mixture / combination of citric acid and urea compound 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.

[0123] The method may include preparing a base composition of the cosmetic composition by combining (a) one or more polyols, (b) a monoalcohol having 2 to 6 carbon atoms, (c) a cationic surfactant, and (d) a fatty compound. Those skilled in the art will understand how to combine the aforementioned compounds so that the base composition is stable and / or homogeneous. In some cases, the base cosmetic composition may be heated, mixed, and / or subjected to shear forces, for example, from an emulsifier.

[0124] Method(s) of Treating Keratin Substrates Aspects of the present disclosure also relate to methods of using such cosmetic compositions.

[0125] Methods of treating keratinous substrates such as hair or skin according to disclosed embodiments typically include: (I) (a) about 20 to about 95 weight percent polyol; (b) from about 5 to about 70% by weight of one or more monoalcohols having 2 to 6 carbon atoms; (c) about 0.1 to about 10 wt. % of one or more cationic surfactants; (d) about 0.1 to about 20% by weight of one or more aliphatic compounds, and (e) about 1 to about 15 wt. % (i) citric acid, and (ii) Urea compounds wherein the weight ratio of the polyol to the monoalcohol(s) (polyol:monoalcohol(s)) is 20:1 to 1:20; and the molar ratio of (i) citric acid to (ii) urea compound is about 10:0.5 to about 0.5:10, wherein the weight percentages are based on the total weight of the cosmetic composition; applying the cosmetic composition to a keratin substrate; (II) optionally rinsing the keratin substrate to remove at least a portion of the cosmetic composition; Including, The keratin substrate may be wet or rinsed with extraneous water before and / or after and / or during application of the cosmetic composition to the substrate.

[0126] A method of treating hair according to disclosed embodiments typically comprises: (I) optionally applying a shampoo to the hair; (II) optionally rinsing the hair to remove at least a portion of the shampoo; (III) (a) about 20 to about 95 weight percent polyol; (b) from about 5 to about 70% by weight of one or more monoalcohols having 2 to 6 carbon atoms; (c) about 0.1 to about 10 wt. % of one or more cationic surfactants; (d) about 0.1 to about 20% by weight of one or more aliphatic compounds, and (e) about 1 to about 15 wt. % (i) citric acid, and (ii) Urea compounds Combination of applying a cosmetic composition comprising: a cosmetic composition comprising: a polyol and monoalcohol(s) in a weight ratio of 20:1 to 1:20 (polyol:monoalcohol(s)); a molar ratio of (i) citric acid to (ii) urea compound in a molar ratio of about 10:0.5 to about 0.5:10, wherein the weight percentages are based on the total weight of the cosmetic composition; (IV) optionally rinsing the hair to remove at least a portion of the cosmetic composition; Includes:

[0127] Methods for treating and / or cleaning hair according to the present disclosure can generally vary, but include applying the cosmetic composition disclosed herein, allowing the cosmetic composition to remain on the hair for a sufficient period 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 need to be removed or rinsed from the hair before styling.

[0128] 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.

[0129] The method may include applying an amount of the cosmetic composition to a keratinous substrate, such as hair or skin, for example, to one or both hands, to the hair, scalp, face, body, etc. The hair or skin may already be wet or damp with exogenous water, or may contain exogenous water after the cosmetic composition has already been applied to the hair or skin. The cosmetic composition and exogenous water may optionally be mixed together on the body skin or hair to facilitate the formation of an opaque emulsion with increased viscosity, a lamellar phase structure, and / or a mixed structure. Alternatively, the cosmetic composition and exogenous water may be combined and, optionally, mixed before application to the hair or skin. For example, the cosmetic composition may be combined in a container and bowl, packaging, bottle, etc., and subsequently applied to the hair or skin after forming an opaque emulsion.

[0130] In some embodiments, the method includes forming a lamellar phase structure, a mixed structure, and / or an opaque emulsion with hands and then applying it to hair or skin. In other embodiments, the method includes forming a lamellar phase structure, a mixed structure, and / or an opaque emulsion directly on hair or skin. When the keratinous substrate to be treated is hair, the emulsion formed by combining the cosmetic composition with water is useful for conditioning, hair management, improving the durability of cosmetic effects, and / or improving the hair's resistance to thermal degradation. The emulsion formed by combining the cosmetic composition with water can be applied to wet or damp hair, and the hair can be massaged and spread throughout the hair, for example, using hands and / or a comb or brush. This results in smoothing and softening of the hair, reducing frizz, dryness, and unwanted volume.

[0131] In some cases, the cosmetic composition is used during a separate, regular shower / bath / cleansing routine, for example, in combination with an additional routine hair care or skin care or skin cleansing composition. The cosmetic composition may be applied to hair or skin individually, or may be combined with one or more additional compositions. For example, the cosmetic composition may be mixed with shampoo (or conditioner) before application to hair. In this case, the mixture of shampoo (or conditioner) and cosmetic composition is simultaneously applied to hair and rinsed from hair during the cleansing 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 hair without rinsing it from the hair, and then 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.

[0132] 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).

[0133] The cosmetic composition of the present disclosure may be left on the hair for a minimum period of time before being rinsed from the hair, however, it is not necessary to leave the cosmetic composition on the hair for an extended period of time. Advantageously, the cosmetic composition can be applied and left on the hair for a period of time typical of ordinary shampooing and / or conditioning. For example, the cosmetic composition (in combination with another hair treatment composition, which may be a shampoo or a conditioner) may be applied to the hair and left on the hair for a few seconds (1, 2, 3, or 5 seconds), up to about 1, about 2, about 5, about 10, about 15, about 20, about 25, or about 30 minutes.

[0134] If the cosmetic composition is not mixed with another composition before application to the hair, the cosmetic composition may be applied to the hair immediately after or just before 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.

[0135] 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.

[0136] As used herein, all ranges provided are meant to include all combinations of subranges within the specified ranges and between the given ranges, so the range 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.

[0137] All ingredients and elements that are affirmatively stated in this disclosure can be negatively excluded from the claims.In other words, the hair cleansing composition of the present disclosure can be free of or essentially free of all ingredients and elements that are affirmatively stated throughout this disclosure.In some instances, the hair cleansing composition of the present disclosure is substantially free of non-incidental amounts of ingredients(s) or compounds(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 non-incidental amounts of ingredients or compounds, but such ingredients(s) or compounds(s) may be present as part of the raw materials that are included as a blend of two or more compounds.

[0138] Some of the components of the various categories identified may overlap. In such cases, if overlap exists and the hair cleansing composition contains both components (or the composition contains two or more overlapping components), the overlapping compounds do not represent more than one component. For example, a compound may be characterized as both an emulsifier and a surfactant. If a particular hair composition contains 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.

[0139] All publications and patent applications mentioned in this specification are herein incorporated 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 referenced publication or patent application, the present disclosure controls.

[0140] 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 encompass the plural as well as the singular. Thus, the term "a mixture thereof" also relates to "mixtures thereof." Throughout this disclosure, the term "mixture thereof," where letters A through F represent elements, is used according to a list of elements, as shown in the following example: "one or more elements selected from the group consisting of A, B, C, D, E, F, and mixtures thereof." The term "mixture thereof" does not require that the mixture contain 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 the mixture 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 members 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."

[0148] Practice of the present disclosure is provided by the following examples, which are not limiting in nature but serve to clarify aspects of the technology.

[0149] Example 1 Cosmetic compositions were prepared from combinations of exemplary base compositions and exemplary deep eutectic solvent (DES) systems, as shown in Tables 1 and 2. The DES system was prepared by heating citric acid and urea in a water bath. Specifically, an exemplary cosmetic composition (Exemplary Composition A) was prepared using the methods discussed herein, combining 95 wt. % of the base composition and 5 wt. % of the deep eutectic solvent ("DES") system. A second exemplary cosmetic composition (Exemplary Composition B) was prepared using the methods discussed herein, combining 90 wt. % of the base composition and 10 wt. % of the DES system. A third exemplary cosmetic composition (Exemplary Composition C) was prepared using the methods discussed herein, combining 98.5 wt. % of the base composition and 1.5 wt. % of the DES system.

[0150] The formulations of exemplary compositions A to C are shown in Table 3. [Table 1] [Table 2] [Table 3]

[0151] Example 2 The effect on the thermal degradation temperature and durability of hair obtained by Exemplary Compositions A and B was evaluated in comparison with the effect obtained by Comparative Composition 1 and the control. Comparative Composition 1 had the same formulation as the base composition provided in Table 1 and was used to prepare Exemplary Compositions A and B.

[0152] Exemplary Compositions A and B and Comparative Composition 1 were applied to bleached hair swatches. The bleached hair swatches were washed and rinsed using a conventional sulfate-based shampoo, and then each cosmetic composition was applied in an amount of approximately 0.1 grams of cosmetic composition per gram of hair swatch. The hair swatches were combed to distribute each cosmetic composition evenly over the hair swatch. After approximately 1 minute, the hair swatches were rinsed with water. A control was prepared by applying a conventional sulfate-based shampoo followed by no cosmetic composition to the hair swatch.

[0153] Hair swatches were evaluated to estimate the effect of Exemplary Compositions A and B and Comparative Composition 1 on the thermal degradation temperature and durability of the hair swatches relative to the control. The hair swatches were subjected to cyclic fatigue to determine the durability of the hair swatches. The cyclic tester simulates daily hair care by subjecting fibers to repeated cyclic tensile deformation until failure. Additionally, differential scanning calorimetry was used to evaluate the thermal degradation temperature, 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.

[0154] As can be seen in Figures 1 and 2, hair swatches receiving Exemplary Compositions A and B had denaturation temperatures of about 136°C and about 137°C, respectively. Comparative Composition 1 and the control both had denaturation temperatures of about 132°C. The durability of hair treated with Exemplary Composition A was surprisingly higher than that of hair treated with Comparative Composition 1 and the control. For example, the durability of hair treated with Exemplary Composition A was about 50% higher than that of hair treated with Comparative Composition 1 and the control. Hair treated with Exemplary Composition B also exhibited higher durability than hair treated with Comparative Composition 1 and the control.

[0155] Example 3 The thermal degradation temperature and durability effects on hair obtained with Exemplary Composition A were evaluated in comparison with those obtained with Comparative Compositions 1-3 and a control. Comparative Composition 2 was prepared by combining 98% by weight of the base composition and 2% by weight of N,N-dimethylurea. Comparative Composition 3 was prepared by combining 97% by weight of the base composition and 3% by weight of citric acid.

[0156] Exemplary Composition A and Comparative Compositions 1-3 were applied to bleached hair swatches. The bleached hair swatches were washed with a conventional sulfate-based shampoo, rinsed, and then approximately 0.1 grams of each of the cosmetic compositions, Exemplary Composition A and Comparative Compositions 1-3, was applied per gram of hair swatch. The hair swatches were combed to distribute each cosmetic formulation evenly across the hair swatch. After approximately 1 minute, the hair swatches were rinsed with water. Controls were prepared according to the above procedure, except that no cosmetic composition was applied to each hair swatch after the conventional sulfate-based shampoo.

[0157] Next, the hair swatches were evaluated to estimate the effects of Exemplary Composition A and Comparative Compositions 1 to 3 on the crosslink density and thermal denaturation temperature corresponding to the durability of the hair swatches, taking into account the control. The thermal denaturation temperature and durability of the hair examined in Example 3 were determined.

[0158] Hair treated with Exemplary Composition A exhibited improved thermal denaturation temperature and significantly improved durability compared to hair treated with Comparative Compositions 1-3 and the control, as seen in Figures 3 and 4.

[0159] Example 4 The thermal degradation temperature and durability effects achieved by Exemplary Composition A were evaluated in comparison with the effects achieved by Comparative Compositions 1-3 and a control on hair. Specifically, Exemplary Composition A and Comparative Compositions 1-3 were applied to bleached hair swatches. The bleached hair swatches were washed and rinsed using a conventional sulfate-based shampoo, and then approximately 0.1 grams of each of the cosmetic compositions, Exemplary Composition A and Comparative Compositions 1-3, was applied per gram of hair swatch. The hair swatches were combed to distribute each cosmetic formulation evenly across the hair swatch. After approximately one minute, the hair swatches were rinsed with water. This procedure of shampooing, rinsing, and applying each cosmetic composition was completed for a total of six cycles. Controls were prepared according to the above procedure, except that no cosmetic composition was applied to each hair swatch after the conventional sulfate-based shampoo.

[0160] The hair swatches were then evaluated to estimate the effect of Exemplary Composition A and Comparative Compositions 1-3 on the crosslink density and thermal degradation temperature corresponding to the durability of the hair swatches, taking into account the control. The thermal degradation temperature and durability of the hair were determined as discussed in Example 3.

[0161] Hair treated with Exemplary Composition A exhibited improved thermal denaturation temperature and significantly improved durability compared to hair treated with Comparative Compositions 1-3 and the control, as seen in Figures 5 and 6.

[0162] Example 5 Hair swatches treated with Exemplary Compositions A and H were evaluated and compared to hair swatches treated with Comparative Composition 1 or a conventional sulfate-based shampoo alone (controls). Exemplary Composition H was prepared by adding a mixture of 6% by weight citric acid and 4% by weight dimethylurea, the balance being water, to the base composition of Table 1 so that the mixture amounted to 5% by weight and the base composition amounted to 95% by weight of the total weight of Exemplary Composition H.

[0163] Caucasian, natural brown, wavy hair swatches were washed and rinsed using a conventional sulfate-based shampoo, followed by application of Exemplary Compositions A and H and Comparative Composition 1. Each hair swatch was massaged with 0.4 grams of each composition per gram of hair swatch for one minute, left on the swatch for an additional minute without rinsing, rinsed for 30 seconds, and then blow-dried for two minutes. These hair swatches were then evaluated using a rinse-off procedure to assess the effectiveness of the compositions. 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.

[0164] Additional hair swatches were prepared by applying the test compositions to the hair swatches in an amount of 0.15 grams of each composition per gram of hair swatch. Specifically, Exemplary Compositions A and H and Comparative Composition 1 were massaged into each hair swatch for 1 minute, left on the hair swatch without rinsing for 1 minute, and then blow-dried for 2 minutes. These hair swatches were evaluated to estimate the effectiveness of the test compositions using the no-rinse procedure.

[0165] The frizz resistance or degree of frizz for each of the hair swatches was assessed using imaging analysis. After blow drying the hair swatches, the frizz resistance of the hair swatches was measured after placing them in a humidity chamber at 80% relative humidity and room temperature for 1 hour.

[0166] Surprisingly, in both the rinse-off and no-rinse procedures, swatches treated with Exemplary Composition A exhibited significantly better anti-frizz properties after treatment and one hour after treatment compared to swatches treated with Comparative Composition 1 or the control, as shown in Figures 7A and 7B. Furthermore, in both the rinse-off and no-rinse procedures, Exemplary Composition H exhibited significantly better anti-frizz properties after treatment compared to swatches treated with Composition 1 or the control. In the no-rinse procedure, Exemplary Composition H exhibited better anti-frizz properties one hour after treatment compared to swatches treated with Comparative Composition 1 or the control.

[0167] Example 6 The thermal degradation temperature and durability effects on hair obtained with Exemplary Composition C were evaluated in comparison with those obtained with Comparative Compositions 1, 4, 5, and a control. Comparative Composition 4 was prepared by combining 99.1 wt. % of the base composition and 0.9 wt. % of citric acid. Comparative Composition 5 was prepared by combining 99.4 wt. % of the base composition and 0.6 wt. % of N,N-dimethylurea.

[0168] Specifically, Exemplary Composition C and Comparative Compositions 1, 4, and 5 were applied to bleached hair swatches. The bleached hair swatches were washed and rinsed using a conventional sulfate-based shampoo, and then approximately 0.1 grams of each of the cosmetic compositions Exemplary Compositions C, Comparative Compositions 1, 4, and 5 were applied per gram of hair swatch. The hair swatches were combed to distribute the respective cosmetic formulations evenly across the hair swatches. After approximately one minute, the hair swatches were rinsed with water. This procedure of shampooing the hair swatches, rinsing the hair swatches, and applying the respective cosmetic compositions was completed for a total of six cycles. Controls were prepared according to the above procedure, except that no cosmetic composition was applied to the respective hair swatches after the conventional sulfate-based shampoo.

[0169] Next, hair was evaluated to estimate the effect of Exemplary Composition C and Comparative Compositions 1, 4, and 5 on the thermal denaturation temperature, which corresponds to the crosslink density and durability of the hair, taking into account the control. The thermal denaturation temperature and durability of the hair were determined as discussed in Example 3.

[0170] Hair treated with Exemplary Composition C exhibited improved thermal denaturation temperatures and significantly improved durability compared to hair treated with Comparative Compositions 1, 4, and 5 and the control, as seen in Figures 8 and 9.

[0171] Example 7 The thermal degradation temperature and durability effects achieved with Exemplary Compositions D-G were compared with those achieved with Comparative Composition 1 and a control. Exemplary Compositions D-G and Comparative Composition 1 were applied to bleached hair swatches. The bleached hair swatches were washed with a conventional sulfate-based shampoo, rinsed, and then Exemplary Compositions D-G and Comparative Composition 1 were applied in an amount of approximately 0.4 grams of each cosmetic composition per gram of hair swatch. The hair swatches were massaged to distribute each cosmetic formulation evenly across the hair swatch. After approximately one minute, the hair swatches were rinsed with water. Controls were prepared according to the above procedure, except that no cosmetic composition was applied to each hair swatch after the conventional sulfate-based shampoo.

[0172] Next, hair was evaluated to estimate the effects of Exemplary Compositions D to G and Comparative Composition 1 on the thermal denaturation temperature corresponding to the crosslink density and durability of hair, taking into account the control. The thermal denaturation temperature and durability of the hair studied in Example 3 were determined.

[0173] As can be seen in Figure 10, exemplary compositions D-G exhibited improved thermal denaturation temperatures compared to hair treated with comparative composition 1 and the control. As can be seen in Figure 11, hair treated with exemplary composition E surprisingly exhibited improved durability.
