Description

COSMETIC COMPOSITIONS, THEIR REQUIREMENTS, AND METHODS OF MAKING AND USING THEM

FIELD OF DISCLOSURE

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

CONTEXT

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

For example, the action of external atmospheric agents such as light and bad weather, and also of thermal, mechanical or chemical treatments, such as brushing, combing, dyeing, bleaching, perms and/or straightening, blow-drying, hair, using a straightening iron, or even repeated washing can damage and alter the hair fibres. Over time, the hair can become dry, rough, brittle or dull, especially in fragile areas, and more particularly at the ends, resulting in split ends.

Thus, to overcome these drawbacks, a common practice consists in resorting to hair care products using compositions intended to condition the hair, to give it satisfactory cosmetic properties, in particular in terms of smoothness, shine, softness, suppleness, lightness, a natural feel and good detangling properties. For example, hair care compositions, such as hair conditioner and/or hair treatment compositions, can be used before or after the hair has been washed with shampoo and/or subjected to chemical treatment. to enhance or return the hair to its natural shine, shine, and softness, or to improve the feel, look, 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, for example, improved hair alignment, reduced unwanted volume (including reduced frizz), and increased shine. There is also a need to develop cosmetic products that can impart other benefits along with care and conditioning benefits, such as styling, volume, shaping, curl definition (for curly or wavy hair) , and ability to restyle or reshape (without the need to re-apply the product).

DISCLOSURE SUMMARY

Aspects of the present disclosure relate to cosmetic compositions and kits thereof. Additional 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.

The cosmetic compositions disclosed herein advantageously provide increased durability and/or strength, noticeable visual shine, fiber alignment, frizz reduction and/or increased hair manageability. Without being limited to any specific theories, the inventors believe that cosmetic compositions, and in particular cosmetic compositions containing certain deep eutectic solvent systems, can diffuse into the hair and form an extensive network. This extended network could strengthen and/or stabilize hair structure, which ultimately reduces frizz associated with high humidity.

Additionally, the cosmetic compositions may be capable of self-associating, typically through hydrogen bond-type interactions, which may allow the cosmetic compositions to strengthen and/or fortify hair, particularly damaged hair. In some embodiments, the cosmetic compositions restore damaged hair. The inventors were also surprised to find that the cosmetic compositions can increase hair stiffness without the use of heat, such as from an iron, hair dryer or the like.

Cosmetic compositions typically include:

(a) about 0.1 to about 25% by weight citric acid;

(b) about 0.2 to about 40% by weight of one or more urea compounds,

DETAILED DESCRIPTION OF THE DISCLOSURE

Certain aspects of the present disclosure relate to cosmetic compositions and their kits. Other aspects of the present disclosure relate to methods of making these cosmetic compositions and methods of using these cosmetic compositions. The cosmetic compositions disclosed herein advantageously provide increased durability and/or strength, noticeable visual gloss, fiber alignment, frizz reduction and/or improved hair manageability.

The inventors have surprisingly found that certain compounds in specific proportions allow cosmetic compositions to provide better durability and strength along with a reduction in hair frizz. Without being limited to any specific theories, the inventors believe that cosmetic compositions, and in particular cosmetic compositions containing certain deep eutectic solvent (SEP) systems, can diffuse into the hair and form an extensive network. This extended network could strengthen and/or stabilize hair structure, which ultimately reduces frizz associated with high humidity.

Cosmetic compositions and/or their ingredients may be capable of self-associating, typically through non-covalent interactions (i.e. hydrogen bonding, ionic and Van Der Waal interactions), which which can enable cosmetic compositions to strengthen and/or stiffen hair, in particular damaged hair. In some embodiments, the cosmetic compositions restore damaged hair. Furthermore, the inventors have surprisingly discovered that these cosmetic compositions can increase the straightness/alignment of hair fibers without the use of heat, such as that of an iron, hair dryer or the like. Cosmetic compositions, such as those containing an SEP system, have also shown evidence of gloss benefits, which are currently being investigated.

Cosmetic compositions according to one aspect of the disclosure typically include:

(a) about 0.1 to about 25% by weight citric acid;

(b) about 0.2 to about 40% by weight of one or more urea compounds,

wherein the weight ratio of the citric acid of (a) to the urea compound of (b) is 1 or less; And

(c) about 20% by weight or more of water,

in which all the percentages by weight are related to the total weight of the cosmetic composition.

The cosmetic compositions can include a deep eutectic ("SEP") solvent system amount. In some cases, the amount of deep eutectic solvent is about 1% by weight or more, preferably about 2% by weight or more, about 3% by weight or more, about 4% by weight 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% , 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% by weight or more, about 34% by weight or more, about 36% by weight or more, about 40% by weight or more, about 45% by weight or more, about 50% by weight or more, or about 60 % by weight or more, based on the total weight of the cosmetic composition.

The cosmetic composition can be formulated such that the weight ratio of citric acid (i) to urea compound (ii) is from about 10:1 to about 2:10. In some instances, the cosmetic composition may be formulated to have a weight ratio of citric acid to urea compound(s) of from about 10:1 to about 0.5:10, about 9:1 to about 0.5:10, 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 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; 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 3:1 to about 2:6; about 3:1 to about 1:10, about 3:1 to about 1:9, about 3:1 to about 1:8, about 3:1 to about 1:7, about 3:1 to about 1:6, about 3:1 to about 2:10, about 3:1 to about 2:9, about 3:1 to about 2:8, about 3:1 to about 2:7, about 3:1 to about 2:6, about 3:1 to about 2:5, about 3:1 to about 2:4, or about 3:1 to about 2:3, about 2:1 to about 2:10, about 1:1 to about 2:10 , about 3:1 to about 2:9, about 3:1 to about 2:8, about 3:1 to about 2:7, about 3:1 to about 2:6, about 3:1 to about 2:5 , about 3:1 to about 2:4, or about 3:1 to about 2:3, including intermediate ranges and subranges (e.g., about 3:1 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.)

Required

Aspects of the present disclosure are directed to kits, which include cosmetic compositions as discussed herein. In one embodiment, the cosmetic compositions of the present disclosure are cosmetic hair and/or hair treatment compositions. For example, the kits can include at least one cosmetic composition according to the present disclosure, such as a cosmetic hair and/or hair treatment composition, and one or more additional compositions, such as a shampoo, a conditioner, etc The various compositions are contained separately in the kits. In some cases, the kits include one or more cosmetic compositions, such as a cosmetic hair or hair treatment composition, according to the present disclosure, a shampoo, a conditioner, a mask, and/or other hair treatment, all of which are contained separately.

The cosmetic compositions of the kit can be packaged in a variety of different containers, such as, for example, a ready-to-use container. Non-limiting examples of useful packaging include tubes, jars, caps, unit dose packages, and bottles, including squeeze tubes, bottles, and sprayable containers. The wrap can be configured so that it can be attached to a wall, such as a wall in a bathroom, including the walls of a shower or bathtub. For example, the package may be a container that is configured to attach to a wall such that when pressure is applied to the container, the composition therein is expelled from one or more openings in the container. In some cases, the packaging is a tube, such as a tube with two compartments, or double tubes, each forming a separate compartment. Each compartment may include a different composition. For example, one tube or compartment may include a cosmetic composition according to the present disclosure, and the other tube may include a composition for use with the cosmetic composition, for example, shampoo, conditioner, all-in-one shampoo/conditioner ( i.e., a conditioning shampoo; also referred to as a "co-wash") mask or other cosmetic products.

Process(es) for producing cosmetic compositions

Certain aspects of the disclosure relate to methods of producing the cosmetic compositions. Processes for producing cosmetic compositions typically include

(I) production of a deep eutectic solvent system comprising:

(a) about 0.1 to about 25% by weight citric acid; And

(b) about 0.2 to about 40% by weight of one or more urea compounds selected from dimethyl urea, hydroxyethyl urea or a combination thereof,

wherein the weight ratio of the citric acid of (a) to the urea compound of (b) is 1 or less; And

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

The process may further include forming the deep eutectic (SEP) solvent system of (I) by mixing the citric acid and the urea compound(s) in certain ratios, for example, as discussed herein . In some cases, the SEP system can be formed at room temperature, such as when citric acid and urea compounds mix in liquid form at room temperature. In other instances, the method also includes heating a 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 citric acid and urea compounds is typically beneficial when the citric acid and urea compounds do not mix in liquid form at room temperature. The mixture/combination of citric acid and urea can be heated to a temperature such that the citric acid and urea compounds mix in liquid form. For example, the mixture/combination of citric acid and urea compounds can be heated to a temperature of about 75°C to about 90°C, about 80°C to about 90°C, about 85°C to about 90°C, from about 70°C to about 85°C, from about 75°C to about 85°C, from about 80°C to about 85°C, from about 70° C to about 80°C, about 75°C to about 80°C, or about 70°C to about 75°C, or any other range or sub-range in between.

The method may include producing a base of the cosmetic composition by combining one or more components, such as fatty compounds, polyols, thickening agents, water-soluble solvents, silicone oils, etc. A person of ordinary skill would understand how to combine the above components and/or compound so that the base of the composition is stable and/or uniform. In some cases, the base of the cosmetic composition can be heated, mixed and/or given shearing forces, for example, from an emulsifier.

Hair treatment method(s)

Certain aspects of the present disclosure also relate to methods of using these cosmetic compositions. A method of treating hair according to aspects of the disclosure typically comprises

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

(II) optionally, rinsing the hair to remove at least some of the shampoo;

(III) the application of a cosmetic composition comprising:

(a) about 0.1 to about 25% by weight citric acid; And

(b) from about 0.2 to about 40% by weight of one or more urea compounds selected from dimethyl urea, hydroxyethyl urea or a combination thereof,

wherein a molar ratio of the citric acid of (a) to the urea compound of (b) is 1 or less; And

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

Methods of treating and/or cleansing the hair may vary depending on the disclosure, but typically include applying a cosmetic composition as disclosed herein, leaving the cosmetic composition on the hair for a sufficient duration and rinsing of the cosmetic compositions from the hair.

In some instances, however, the cosmetic composition may be a leave-on composition. For example, the cosmetic compositions can remain on the hair indefinitely, that is to say the cosmetic composition is not removed or rinsed from the hair before styling it.

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

The cosmetic compositions are useful for conditioning, hair management, improving the durability and/or resistance of hair to thermal breakdown. The cosmetic compositions can be applied to wet or damp hair and can be massaged into the hair, for example, with the hands, and/or distributed over the entire hair with a comb or a brush. This results in smoothing and softening of the hair, which reduces frizz, dryness and unwanted volume. It is also possible to combine, and optionally mix, the cosmetic composition and the extraneous water before applying it to the body. For example, the cosmetic composition can be combined in a container, bowl, wrapper, bottle, etc. and then applied to the body after the formation of the opaque emulsion.

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

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

The cosmetic compositions of the present disclosure can be left on the hair for a minimum period of time before rinsing them from the hair, but it is not necessary to leave the cosmetic composition on the hair for an extended period of time. Conveniently, the cosmetic compositions can be applied and left on the hair for a period of time that is typical for regular shampooing and/or conditioning. For example, the cosmetic composition (whether combined with another hair treatment composition such as a shampoo or conditioner) can be applied to the hair and left on the hair for a few seconds (1, 2, 3, or 5 seconds) until about 1 , about 2 , about 5 , about 10 , about 15 , about 20 , about 25 , or about 30 minutes.

When the cosmetic composition is not mixed with another composition before application to the hair, the cosmetic composition can be applied to the hair immediately after or before the hair is (is) treated with another composition (for example, a shampoo and/or or a conditioner). For example, the cosmetic compositions can be applied to the hair within seconds or 1, 2, 5, 10, or 20 minutes before or after a shampoo and/or conditioner is (or is) applied to the hair.

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

All components and elements positively specified in this disclosure may be negatively excluded from the claims. In other words, the hair washing compositions of this disclosure may be free or substantially free of all of the components and elements positively cited throughout this disclosure. In some cases, the hair washing compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound which is added to the hair washing composition by itself. For example, a hair wash composition may be substantially free of a non-incidental amount of an ingredient or compound, although such ingredient(s) or compound(s) may be present. ) as part of a raw material that is included as a mixture of two or more compounds.

Some of the various component categories identified may overlap. In such cases where an overlap may exist and the hair washing composition includes both components (or the composition includes more than two overlapping components), an overlapping compound does not represent more than one component. For example, some compounds can be characterized as both an emulsifier and a surfactant. If a particular hair composition includes both an emulsifier and a surfactant, compounds that can be characterized as both an emulsifier and a surfactant will only serve as either an emulsifier or a surfactant - not both.

All publications and patent applications cited in the specification are hereby incorporated by reference, for all intents and purposes, as if each publication or patent application were specifically and individually indicated as incorporated by reference. In the event of any inconsistency between this disclosure and any publication or patent application incorporated herein by reference, this disclosure shall prevail.

EXAMPLES

Implementation of this disclosure is provided by means of the following examples. The following examples serve to elucidate certain aspects of the technology without being limiting in nature.

Example 1

Three exemplary cosmetic compositions (exemplary compositions A-C) were prepared from the deep eutectic ("SEP") solvent system. The SEP system was prepared by mixing citric acid and dimethyl urea at a temperature of about 80°C to about 85°C. The SEP system was then solubilized in distilled water. The formulation of exemplary compositions A-C are provided in Table 1 below.

Example 2

Exemplary Compositions B and D were applied to locks of hair and evaluated against the application of a conventional sulfate-based shampoo (the control). Exemplary Composition D had the same formulation as Exemplary Composition B, except that an SEP system was not formed from citric acid and dimethyl urea prior to preparation of the cosmetic composition.

Strands of wavy natural brown Caucasian hair (medium curls) were washed with a conventional sulfate-based shampoo and rinsed prior to application of Exemplary Compositions B and D. An amount of 0.4 grams of each of Exemplary Compositions B and D per gram of hair sample was massaged into their respective samples for 1 minute, left on the hair strands for another minute, rinsed out for 30 seconds, then blow-dried for 2 minutes. These locks of hair were then evaluated to determine the effects of Exemplary Compositions B and D using a rinse out procedure. The control was prepared according to the above procedure, except that no cosmetic composition was applied to the lock of hair after the conventional sulphate-based shampoo.

Additional locks of hair were prepared by applying Exemplary Compositions B and D to locks of hair at 0.15 grams of composition per gram of respective locks of hair. Specifically, Exemplary Compositions B and D were massaged into their respective locks of hair for one minute, left on the locks of hair for one minute, and then blow-dried for two minutes. These locks of hair were evaluated to determine the effects of Exemplary Compositions B and D using a leave-in procedure.

The anti-frizz properties or degree of frizz on each of the hair strands was assessed using imaging analysis. The anti-frizz properties of the locks of hair were evaluated after the locks of hair were blow-dried, and after 1 hour, after 2 hours, after 4 hours, after 8 hours, after 12 hours, and after 24 hours of residence of the locks of hair in a humidity chamber at 80% relative humidity and at room temperature.

FIG. 1 shows images of the hair strands treated with Exemplary Compositions B and D and the control by the rinse-out procedure. FIG. 2 provides images of locks of hair treated with Exemplary Compositions B and D and the control by the leave-in procedure. As shown in Figures 1 and 2, Exemplary Compositions B and D provide significantly superior anti-frizz properties to control locks of hair. Additionally, Exemplary Compositions B and D provided better hair volume control. Exemplary composition B provides surprisingly better volume control than exemplary composition D and the control, as shown in Table 2.

Example 3

Locks of hair treated with Exemplary Compositions A and C were evaluated and compared to locks of hair treated only with a conventional sulfate-based shampoo (the "control"). The locks of hair were washed with a conventional sulfate-based shampoo and rinsed before the application of exemplary compositions A and C at the rate of 0.15 grams of composition per gram of respective locks of hair. The compositions were massaged into their respective hair strands for one minute, left on the hair strands for one minute, and then blow-dried for two minutes. The control was prepared according to the above procedure, except that no cosmetic composition was applied to the lock of hair after the conventional sulphate-based shampoo.

These locks of hair were evaluated to assess the effects of Exemplary Compositions A and C using a leave-in procedure. Hair strands underwent cyclic fatigue using a cyclic tester to determine the durability of the hair sample. The Cyclic Tester simulates daily hair grooming by subjecting a set number of fibers to repeated cyclic tensile strains until failure. Additionally, the hair strands were evaluated for thermal denaturation temperature, which is associated with the crosslink density of the amorphous matrix, using differential scanning calorimetry. Differential scanning calorimetry measures the thermal stability of the main morphological components of the hair.

As seen in Figures 3 and 4, the lock of hair treated with Exemplary Compositions C exhibited significantly better durability and denaturation temperature than the control lock of hair. The lock of hair treated with Exemplary Compositions A also exhibited improved durability and denaturation temperature compared to the control lock of hair.

Example 4

Locks of hair treated with Exemplary Compositions A and E and Comparative Compositions 1 and 2 were evaluated against locks of hair treated only with conventional sulfate-based shampoo (the control). Exemplary Composition E had the same formulation as Exemplary Composition A except that an SEP system was not prepared from citric acid and dimethyl urea prior to preparing the cosmetic composition. The formulations of Comparative Compositions 1 and 2 are provided in Table 3.

US INCI name Comp. 1 Comp. 2 Citric acid CITRIC ACID 0.6% by weight Urea DIMETHYL UREA 0.9% by weight Water WATER Q.S. 100 Q.S. 100

An amount of 0.4 grams each of Exemplary Compositions A and E and Comparative Compositions 1 and 2 per gram of hair sample was massaged into their respective hair locks for 1 minute, left on the hair locks for one another minute, rinsed for 30 seconds, then blow-dried for 2 minutes. These locks of hair were then evaluated to determine the effects of Exemplary Compositions A and E and Comparative Compositions 1 and 2 using a rinse-out procedure. The control was prepared according to the above procedure, except that no cosmetic composition was applied to the lock of hair after the conventional sulphate-based shampoo.

An additional lock of hair was treated with an amount of 0.15 grams of Exemplary Composition A per gram of the lock of hair. Exemplary Composition A was massaged into the corresponding lock of hair for one minute, left on the lock of hair for one minute, and then blow-dried for two minutes. The lock of hair was evaluated to determine the effects of Exemplary Composition A using a leave-in procedure.

The hair was then estimated in order to evaluate the effect of the exemplary composition A and E on the thermal denaturation temperature (which corresponds to the density of the crosslinking), the durability of the hair, the Young's modulus and the elongation at break relative to the effects of comparative compositions 1 and 2 and the control. The thermal denaturation temperature and the durability of the hair were determined as indicated in Example 2.

Hair treated with the rinse-out and leave-in procedures with Exemplary Composition A showed significantly better durability, as measured by break cycles, and better denaturation temperature. For example, hair treated with Exemplary Composition A showed approximately 40% increased durability over Comparative Compositions 1 and 2. Similarly, the elongation at break and Young's modulus of hair treated with Exemplary Composition A were better than the elongation at break of hair treated with Comparative Compositions 1 or 2. elongation at break of hair treated with exemplary compositions A and E compared to comparative compositions 1 and 2 and to the control.
