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

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

For example, the action of external atmospheric conditions, such as light, bad weather, as well as heat, mechanical or chemical treatments, such as brushing, combing, dyeing, bleaching, permanent-waving and/or relaxing, Blow-drying, flat ironing, or even repeated washing can damage and weaken hair fibers. Over time, hair can become dry, coarse, brittle or dull, especially in areas prone to damage, and more specifically at the ends, leading to split ends.

Therefore, in order to overcome the above drawbacks, resort to hair care products using compositions intended to condition hair, especially in terms of smoothness, shine, softness, suppleness, lightness, natural feel and good disentangling properties. It is customary to provide a beautiful cosmetic character. For example, hair care compositions, such as hair conditioner and/or treatment compositions, improve or restore to hair its natural shine, luster, and softness, or improve the feel, appearance, and handling of hair. It can be used before or after washing the hair with shampoo and/or subjecting it to a chemical treatment to improve it.

It is understood that different types of hair care and skin care compositions may provide different benefits.

However, there is still a need to provide improved hair handling, eg improved hair alignment, reduced unwanted volume (particularly reduced frizz), and increased gloss. In addition to the care and conditioning benefits (without the need to reapply the product), there are other benefits at the same time, such as styling, volume, shaping, definition of curl (for curl or wavy hair), and restylability. There is a need to develop cosmetics that can impart restylability or reshaping.

Aspects of the present disclosure relate to cosmetic compositions and kits thereof. Additional aspects of the present disclosure relate to methods for making such cosmetic compositions and methods of using such cosmetic compositions for keratinous materials such as hair and skin.

When the keratinous substrate is hair, particularly hair on human head, the cosmetic composition of the present disclosure simultaneously achieves both surface and deep repair to the hair.

Additionally, the present inventors can determine a certain compound and a specific weight and weight prior to forming a cosmetic composition, such as by forming a deep eutectic solvent system ("DES") system prior to incorporation into a base composition comprising the cosmetic composition. It has been recognized that/or forming a DES system from the combination in molar ratio enhances the benefits achieved by the cosmetic composition.

Additionally, the cosmetic composition may be formulated to form a lamellar phase when the cosmetic composition is mixed with extraneous water. Without being limited by any particular theory, the lamellar structure formed by the cosmetic composition may further enhance the benefits achieved by the cosmetic composition, in particular improving the handling of hair and/or reducing frizz. it is believed to be

When the keratinous substrate is hair, especially hair on human head, the cosmetic composition of the present disclosure simultaneously achieves both surface and deep repair to the hair. The present inventors have surprisingly found that certain compounds and their associations in specific weight and/or molar ratios enable cosmetic compositions to significantly improve the durability and resistance of hair to thermal degradation.

The citric acid and urea, or a portion thereof, may form a deep eutectic solvent system ("DES") system before being incorporated into the base composition of a cosmetic composition. The base composition of the cosmetic composition may be a composition of one or more constituents of the cosmetic composition. For example, in some cases, the foundation composition may include all components of a cosmetic composition except for citric acid and urea compound(s). The cosmetic composition may include the DES system at least partially after the DES system is incorporated into the basic cosmetic composition. Additional descriptions of the DES systems and methods for fabricating the DES systems are disclosed herein.

During use, the user combines the cosmetic composition with foreign water (eg, water other than water already included in the cosmetic composition). When the cosmetic composition is mixed with or brought into contact with foreign water, the cosmetic composition may form a lamellar phase structure. "Lamellar phase structure" generally relates to the packing of polar-headed long-chain non-polar-tailed molecules as sheets of bilayers separated by the bulk of the liquid in an environment of the bulk of the polar liquid (i.e., water from the hair). In some cases, the cosmetic composition may form a mixed structure when combined with foreign water. As used herein, the term “mixed structure” refers to a combination of lamellar phases and crystals. Additionally or alternatively, the cosmetic composition may form an opaque or cloudy emulsion when combined with extrinsic water.

In some cases, the cosmetic composition comprises foreign water and the cosmetic composition in a ratio (water:composition) ranging from 0.1:1 to 3:1, preferably 0.5:1 or 1:1 or 1.5:1 or 2:1. When combined with, they form lamellar phase structures, mixed structural phases, and/or opaque emulsions. Additionally and/or alternatively, formation of a lamellar phase structure, a mixed structure phase, and/or an opaque emulsion may occur when the total amount of water in the cosmetic composition, based on the total weight of the cosmetic composition prior to combining with extraneous water, is 10 weight percent or more, and in some cases, 12 weight percent or more, 15 weight percent or more, 20 weight percent or more, 25 weight percent or more, or 30 weight percent or more. In some embodiments, the opaque or cloudy emulsion has a viscosity equal to or greater than that of the composition prior to combining with exogenous water.

The cosmetic composition has a lamellar structure, a mixed structure, and/or upon contact with, for example, a user's wet or damp hands, wet or damp skin, wet or damp hair, and/or external water from a faucet. or an opaque emulsion may be formed. This may occur, for example, when the consumer applies the cosmetic composition to wet or damp areas of the body (eg, hands, face, skin, hair, etc.). The user can then physically manipulate the applied cosmetic composition (eg, by rubbing their hands together or rubbing the composition against other parts of the body, such as the face, hair, etc.). In some cases, the formation of lamellar phase structures, mixed structure phases, and/or opaque emulsions occurs automatically without the need for mixing. In other words, the cosmetic composition is sufficiently combined with the foreign water by simply contacting the foreign water. However, in some cases, a minimal amount of mixing may be necessary and may be recommended.

The mixed structure formed from the combination of the cosmetic composition and foreign water may occur without active mixing from the user or with active mixing from the user.

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

wherein the weight ratio of polyol to monoalcohol(s) (polyol:monoalcohol(s)) is from 20:1 to 1:20;

The molar ratio of the citric acid of (i) to the urea compound of (ii) is from about 10:0.5 to about 0.5:10, all weight percentages based on the total weight of the cosmetic composition.

Methods for treating and/or cleaning hair according to the present disclosure may vary, but typically include applying a cosmetic composition as disclosed herein, leaving the cosmetic composition on the hair for a sufficient period of time, and rinsing the cosmetic composition from hair. However, in some cases, the cosmetic composition may be a leave-in composition. For example, the cosmetic composition can be left on the hair indefinitely, ie, the cosmetic composition is not removed or rinsed from the hair prior to styling the hair.

The cosmetic composition may be applied to hair in 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.

The method may include applying a predetermined amount of the cosmetic composition onto a keratinous substrate such as hair or skin, for example, one or both hands, hair, scalp, face, body, and the like. The hair or skin may already be wet or damp with foreign water, or the foreign water may be included after the cosmetic composition has already been applied to the hair or skin. The cosmetic composition and foreign water may optionally be mixed together on the skin or hair of the body 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 foreign water may be combined and optionally mixed prior to application to hair or skin. For example, the cosmetic composition may be combined in a container, bowl, package, bottle, etc., and subsequently applied to hair or skin after forming an opaque emulsion.

In some cases, the method includes manually forming a lamellar phase structure, blended structure, and/or opaque emulsion and subsequently applying it to the hair or skin. In other cases, the method includes forming a lamellar phase structure, mixed structure, and/or opaque emulsion directly on the hair or skin. When the keratinous substrate to be treated is hair, the emulsion formed by the combination of the cosmetic composition and water conditions and cares the hair, improves the durability of the cosmetic effect, and/or increases the hair's resistance to thermal degradation. useful for improving The emulsion formed by combining the cosmetic composition and water can be applied to wet or damp hair, for example, massaged into the hair by hand, and/or spread over the entire hair with a comb or brush. This causes softness and weakening of the hair, reducing frizz, dryness, and unwanted volume.

In some cases, the cosmetic composition is routinely used in conjunction with an additional hair-care or skin care or skin cleansing composition, eg, during an individual's normal shower/bath/cleansing routine. The cosmetic composition may be applied to the 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) prior to application to hair. In this case, the mixture of shampoo (or conditioner) and cosmetic composition is simultaneously applied to and rinsed from the hair during the washing or conditioning process. Alternatively, the cosmetic composition may be layered (or lathered) over 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 and not rinsed from the hair, and then a shampoo (or conditioner) is subsequently applied to the hair. Alternatively, the shampoo (or conditioner) may be first applied to the hair and not rinsed with the shampoo (or conditioner) from the hair, and the cosmetic composition is also applied to the hair.

When used in combination with shampoo and/or conditioner, the cosmetic composition is 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 A ratio of 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.) It can be mixed with or used in combination with shampoo and/or conditioner.

The cosmetic composition of the present disclosure may be allowed to remain on the hair for a period of up to one minute before being rinsed from the hair, but the cosmetic composition need not be left on the hair for an extended period of time. Conveniently, the cosmetic composition can be applied and left on the hair for a typical period of time for normal shampooing and/or conditioning. For example, the cosmetic composition (regardless of whether it is combined with other hair-treatment compositions such as shampoo or conditioner) is applied to the hair for several seconds (1, 2, 3, or 5 seconds) up to about 1, about 2, It can be left on the hair for about 5, about 10, about 15, about 20, about 25, or about 30 minutes.

When the cosmetic composition is not mixed with other compositions prior to application to the hair, the cosmetic composition may be applied to the hair immediately or immediately before the hair is treated with another composition (eg, shampoo and/or conditioner). For example, the cosmetic composition may be applied to the hair about several seconds or 1, 2, 5, 10, or 20 minutes before or after shampoo and/or conditioner are applied to the hair.

Example 2

The effects of heat denaturation temperature and durability imparted by Exemplary Compositions A and B on hair were evaluated in comparison with the effects imparted by Comparative Composition 1 and Control. Comparative Composition 1 has the same formulation as the base composition provided in Table 1 used to prepare Exemplary Compositions A and B.

Exemplary Compositions A and B and Comparative Composition 1 were applied to bleached hair swatches. After washing and rinsing the bleached hair swatch with a conventional sulfate-based shampoo, the cosmetic composition was applied in an amount of about 0.1 gram of the cosmetic composition per gram of hair swatch. The hair sample was combed to spread the cosmetic composition evenly on the hair sample. After about 1 minute, the hair swatch was rinsed with water. A control was prepared by applying only a conventional sulfate-based shampoo to a hair swatch without subsequently applying a cosmetic composition.

The hair swatches were evaluated by evaluating the effects of Exemplary Compositions A and B and Comparative Composition 1 on the heat denaturation 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 mimics daily hair grooming by subjecting fibers to repeated cyclic tensile strains until failure. Additionally, the hair swatches were evaluated for heat denaturation temperature associated with the cross-link density of the amorphous matrix using differential scanning calorimetry. Differential scanning calorimetry measures the thermal stability of the major morphological components of hair.

As shown in FIGS. 1 and 2 , hair swatches that received Exemplary Compositions A and B had denaturing temperatures of about 136° C. and about 137° C., respectively. Comparative Composition 1 and Control both had a denaturation temperature 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% greater than the durability of hair treated with Comparative Composition 1 and the control. Hair treated with Exemplary Composition B also showed higher durability than hair treated with Comparative Composition 1 and the control.

Example 3

The effect of heat denaturation temperature and durability imparted by Exemplary Composition A on hair was evaluated by comparison with the effects imparted by Comparative Compositions 1-3 and the control. Comparative Composition 2 was prepared by combining 98% by weight of the base composition and 2% by weight of N,N-dimethyl urea. Comparative composition 3 was prepared by combining 97% by weight of the base composition and 3% by weight of citric acid.

Exemplary Composition A and Comparative Compositions 1-3 were applied to bleached hair swatches. After washing and rinsing the bleached hair swatch with a conventional sulfate-based shampoo, Exemplary Composition A and Comparative Compositions 1-3 were applied in an amount of about 0.1 gram of the cosmetic composition per gram of hair swatch. The hair sample was combed to spread the cosmetic formulation evenly on the hair sample. After about 1 minute, the hair swatch was rinsed with water. A control group was prepared according to the above procedure except that the cosmetic composition was not applied to the corresponding hair sample after a conventional sulfate-based shampoo.

Then, the hair swatches were evaluated by evaluating the effect of Exemplary Composition A and Comparative Compositions 1-3 on the heat denaturation temperature corresponding to the crosslink density and durability of the hair swatches in light of the control group. The heat denaturation temperature and durability of the hair was determined as discussed in Example 3.

As shown in Figures 3 and 4, hair treated with Exemplary Composition A exhibited improved heat denaturation temperature and significantly improved durability compared to hair treated with Comparative Compositions 1-3 and the control.

Example 4

The heat denaturation temperature and durability effect imparted by Exemplary Composition A were evaluated by comparison with the effects imparted to hair by Comparative Compositions 1-3 and the control group. In particular, Exemplary Composition A and Comparative Compositions 1-3 were applied to bleached hair swatches. After washing and rinsing the bleached hair swatch with a conventional sulfate-based shampoo, Exemplary Composition A and Comparative Compositions 1-3 were applied in an amount of about 0.1 gram of the cosmetic composition per gram of hair swatch. The hair sample was combed to spread the cosmetic formulation evenly on the hair sample. After about 1 minute, the hair swatch was rinsed with water. The above procedure of shampooing the hair sample, rinsing the hair sample, and applying the cosmetic composition was completed in a total of 6 cycles. A control group was prepared according to the above procedure except that the cosmetic composition was not applied to the corresponding hair sample after a conventional sulfate-based shampoo.

Then, the hair swatches were evaluated by evaluating the effect of Exemplary Composition A and Comparative Compositions 1-3 on the heat denaturation temperature corresponding to the crosslink density and durability of the hair swatches in light of the control group. The heat denaturation temperature and durability of the hair was determined as discussed in Example 3.

As shown in Figures 5 and 6, hair treated with Exemplary Composition A exhibited improved heat denaturation temperature and significantly improved durability compared to hair treated with Comparative Compositions 1-3 and the control.

Example 5

Hair swatches treated with Exemplary Compositions A and H were evaluated in comparison with hair swatches treated with Comparative Composition 1 or conventional sulfate-based shampoo only (control). Exemplary Composition H was prepared by adding to the base composition of Table 1 a mixture containing 6% by weight of citric acid and 4% by weight of dimethyl urea, the remainder of the mixture being water, the mixture being 5% by weight of the total weight of Exemplary Composition H. , and the base composition was in an amount of 95% by weight.

Natural brown wavy Caucasian hair swatches were washed and rinsed with a conventional sulfate-based shampoo, then Exemplary Compositions A and H and Comparative Composition 1 were applied. An amount of 0.4 grams of each composition per gram of hair swatch was massaged onto the hair swatch for one minute, left on the hair swatch for an additional minute, rinsed for 30 seconds, and then blow-dried for 2 minutes. The hair swatches were then appraised to evaluate the effectiveness of the composition using a rinse-off procedure. A control group was prepared according to the above procedure except that the cosmetic composition was not applied to the hair swatch after a conventional sulfate-based shampoo.

Additional hair swatches were prepared by applying the test composition to the hair swatch in an amount of 0.15 grams of the composition per gram of that hair swatch. Specifically, Exemplary Compositions A and H and Comparative Composition 1 were massaged onto the hair swatch for 1 minute, left on the hair swatch for 1 minute, and then blow-dried for 2 minutes. The hair swatches were appraised to evaluate the effectiveness of the test composition using a leave-on procedure.

Imaging analysis was used to determine the degree of frizz or anti-frizz properties for each hair sample. The hair swatches were blow dried and the anti-frizz properties of the hair swatches were measured after placing the hair swatches in a humidity chamber at 80% relative humidity and room temperature for 1 hour.

Surprisingly, as shown in FIGS. 1A and 7B , swatches treated with Exemplary Composition A for both rinse-remove and leave-in procedures did not differ from swatches treated with Comparative Composition 1 or controls after treatment and 1 hour after treatment. showed significantly better anti-frizz properties in comparison. In addition, Exemplary Composition H, for both rinse-off and leave-in procedures, exhibited significantly better anti-frizz properties after treatment compared to swatches or controls treated with Composition 1. For the leave-in procedure, Exemplary Composition H showed better anti-frizz at 1 hour post treatment compared to swatches or controls treated with Comparative Composition 1.

Example 6

The effects of heat denaturation temperature and durability imparted to hair by Exemplary Composition C were evaluated by comparison with the effects imparted by Comparative Compositions 1, 4, and 5 and the control group. Comparative Composition 4 was prepared by combining 99.1% by weight of the base composition and 0.9% by weight of citric acid. Comparative composition 5 was prepared by combining 99.4% by weight of the base composition and 0.6% by weight of N,N-dimethyl urea.

Specifically, Example Composition C and Comparative Compositions 1, 4, and 5 were applied to bleached hair swatches. After washing and rinsing the bleached hair swatch with a conventional sulfate-based shampoo, Exemplary Composition C and Comparative Compositions 1, 4, and 5 were applied in an amount of about 0.1 gram of the cosmetic composition per gram of hair swatch. The hair sample was combed to spread the cosmetic formulation evenly on the hair sample. After about 1 minute, the hair swatch was rinsed with water. The above procedure of shampooing the hair sample, rinsing the hair sample, and applying the cosmetic composition was completed in a total of 6 cycles. A control group was prepared according to the above procedure except that the cosmetic composition was not applied to the corresponding hair sample after a conventional sulfate-based shampoo.

Then, the hair was evaluated by evaluating the effects of Exemplary Composition C and Comparative Compositions 1, 4, and 5 on the heat denaturation temperature corresponding to the crosslink density and durability of the hair in the light of the control group. The heat denaturation temperature and durability of the hair was determined as discussed in Example 3.

As shown in Figures 8 and 9, hair treated with Exemplary Composition C exhibited improved heat denaturation temperature and significantly improved durability compared to hair treated with Comparative Compositions 1, 4, and 5 and the control.

Example 7

The heat denaturation temperature and durability effects imparted by Exemplary Compositions D-G were compared to the effects imparted by Comparative Composition 1 and Control. Exemplary Compositions D-G and Comparative Composition 1 were applied to bleached hair swatches. After washing and rinsing the bleached hair swatches with a conventional sulfate-based shampoo, Exemplary Compositions D-G and Comparative Composition 1 were applied in an amount of about 0.4 grams of the cosmetic composition per gram of hair swatches. The hair sample was massaged to spread the cosmetic formulation evenly on the hair sample. After about 1 minute, the hair swatch was rinsed with water. A control group was prepared according to the above procedure except that the cosmetic composition was not applied to the corresponding hair sample after a conventional sulfate-based shampoo.

Then, the hair was evaluated by evaluating the effects of Exemplary Compositions D-G and Comparative Composition 1 on the heat denaturation temperature corresponding to the crosslink density and durability of the hair in the light of the control group. The heat denaturation temperature and durability of the hair was determined as discussed in Example 3.
