Description

Title of the invention: COMPOSITIONS AND METHODS FOR STYLING HAIR Technical field

[0001] The present disclosure relates to compositions and methods for styling hair, particularly to compositions and methods for temporarily straightening curly or wavy hair. CONTEXT

[0002] Consumers with curly or wavy hair often want to temporarily straighten their hair to change its appearance, then return to their curly hairstyle without damaging it. Additionally, reducing the curl of very curly hair can increase the manageability and ease of styling of that hair.

[0003] Currently, temporary straightening of curly / wavy or frizzy hair usually involves the use of hot tools such as hair dryers and / or flat irons. The high temperature of hair dryers and / or flat irons causes the hydrogen bonds in the hair keratin to break, allowing for temporary straightening. The hydrogen bonds are formed again by the action of moisture, so that the hair returns to its original shape over time due to humidity in the air or after being washed or moistened.

[0004] Long-term and / or permanent hair straightening is generally achieved using chemical hair straightening treatments, such as relaxers, at a high pH. The shape of the hair is primarily determined by the disulfide bonds connecting two cysteine ​​moieties of the hair keratin. To achieve a long-lasting and / or lasting sculpting or styling effect, it is generally necessary to separate the disulfide bonds by the action of a reducing agent or a straightening agent containing a sulfide or thiol group. Once the hair has been brought into the desired shape, new disulfide bonds are formed by applying an oxidizing agent such as hydrogen peroxide, thereby fixing the shape of the hair. However, the use of such agents can damage the hair and weaken it, leading to subsequent breakage.Conventional products that provide hold, such as styling gels, but can also provide hair straightening effects, usually flake off the hair and make the hair look very stiff and unnatural. In addition, conventional straightening routines are usually very time-consuming.

[0005] There is therefore a need for new and improved compositions that can be simply applied to the hair and provide smoothing effects to curly or wavy hair that would not damage the hair, while imparting various additional sensory properties to hair such as frizz control, softness, smoothness and / or shine. The present disclosure addresses these needs and concerns and relates to novel compositions and methods that can provide a styling effect, particularly a temporary straightening effect on curly / wavy hair without the need to use heat.

[0006] It has now been surprisingly found that a combination of components described herein provides a balance between straightening performance and the desired look and feel of the consumer, even in high humidity conditions, and is useful for providing a desired temporary straightening effect to curly or wavy hair through a simple application routine without the use of hot tools or harsh chemicals such as reducing agents or relaxers, while providing additional sensory benefits such as frizz control, natural look and feel, to the hair. The temporary straightening effect and other benefits such as frizz control provided to the hair are long-lasting, as it can last in high humidity conditions and until the next hair wash, without damaging the natural curls. SUMMARY

In some embodiments, the compositions are a non-aerosol type product, which may be dispensed from a bottle, tube, or spray bottle.

[0085] In some embodiments, the compositions may be a hair treatment or conditioning product, a hair styling product, or a product that styles hair while providing treatment and / or conditioning benefits. II. Procedures

[0086] The compositions disclosed herein may be used for styling hair, particularly for temporarily straightening curly or wavy hair. Furthermore, the compositions disclosed herein are surprisingly capable of providing a variety of additional desirable sensory properties, e.g., anti-frizz, hy conditioning, softness, smoothness and / or shine to the hair. As such, the present disclosure also relates to methods of styling hair, in particular the temporary straightening of curly or wavy hair, while caring for the hair and providing it with one or more sensory benefits described above.

[0087] The methods of the disclosure generally include applying an effective amount of a composition disclosed herein to hair that has waves or curls, and smoothing. As used herein, the term "effective amount" refers to an amount sufficient to impart a desired smoothing effect to the hair, taking into account the degree of curl, length, volume, and texture of the hair, and / or an amount sufficient to impart a desired sensory benefit to the hair. Generally, about 0.5 g to about 50 g of product is applied to the hair, depending on the product formula, length, volume, and type of hairstyle. The composition applied to the hair may, for example, be distributed evenly by combing it with the fingers or by means such as a comb or the like.Once the composition is evenly distributed throughout the hair, the hair should be allowed to air dry for the required time, e.g. at least 15 minutes, at least 30 minutes, at least 1 hour or up to 6 hours, until dry. In some circumstances, instead of allowing the hair to air dry under room conditions, it may be dried using a ball dryer or a hair dryer at room temperature, e.g. below 50^C, e.g. 40-45°C. Once the hair is dry, the hair is combed with the fingers (running the fingers through the hair) or with a comb or similar tool to break the film or coating formed by the compositions on the hair in order to smooth it and / or achieve a less rigid and more natural movement.Generally, no thermal or chemical relaxer is applied to the hair before, during, or after the styling composition is applied to the hair.

[0088] The composition may remain on the hair as a leave-in product for the required duration, for example a few hours or a few days, or until the next washing or rinsing of the hair. The composition applied to the hair may remain on the hair overnight or for the desired duration, until the next washing of the hair.

[0089] In some embodiments, before applying the composition to the hair, the hair may first be cleansed with a commercially available shampoo and / or rinsed with water. The composition may then be applied to the washed and / or rinsed hair, preferably when the hair is wet, damp, or moist. In some other embodiments, before applying the composition to the hair, if the hair is dry, it may be moisturized, dampened, or wetted by spraying water or using a damp towel.

[0090] The methods of the disclosure generally do not require the use of a reducing agent, including a base, particularly a strong base (as in alkaline laundry and relaxers that use a metal hydroxide), or heating the hair to achieve a temporary straightening effect. Thus, in some embodiments, the method does not include the use of a chemical straightening agent, reducing agent, or base, and / or does not include heating the hair.

[0091] In various embodiments, methods of treating hair with the compositions of the disclosure provide the above-described benefits to the hair, without a greasy feel or flaking, compared to hair that has not been treated with a composition of the disclosure. The benefits provided to the hair may remain for a desired duration, such as a few hours, a few days, or until the hair is rinsed or washed.

[0092] The compositions described herein are not mascara compositions, i.e., are not intended to be applied to eyelashes and / or eyebrows. The compositions are also not makeup compositions, i.e., are not intended to be applied to the skin, particularly the face, body, or lips. Thus, treatment or application to hair is intended to be limited to hair, i.e., the scalp, and not eyelashes, eyebrows, body or facial hair, or the like. In such embodiments, a skilled person understands that "hair" refers to hair growing on the scalp, and excludes eyebrows, eyelashes, facial hair, etc.

[0093] Having described in detail the numerous embodiments of the present invention, it will be apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims. Further, it should be appreciated that all examples of the present disclosure, while illustrating numerous embodiments of the disclosure, are provided by way of non-limiting examples and therefore should not be construed as limiting the various aspects thus illustrated. It should be understood that all definitions herein are provided for the purposes of the present disclosure only.

[0094] As used herein, the terms "comprising," "having," and "including" (or "comprise," "have," and "include") are used in their broad, non-limiting sense. The phrase "consisting essentially of" limits the scope of a claim to specified materials or steps and to those that do not materially affect the fundamental and novel feature(s) of the compositions.

[0095] In this application, the use of the singular includes the plural, unless specifically indicated otherwise. The singular forms "a", "an", "the", "the" and "at least one" are understood to include the plural as well as the singular, unless the context clearly dictates otherwise, and these expressions, as well as the expression "one or more" which means "at least one", are expressly intended to include the individual components as well as mixtures / combinations thereof. Similarly, the expression "a salt thereof" also refers to "salts thereof". Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or a mixture thereof," it indicates that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included. However, it should be understood that this language also includes embodiments where G, H, I, etc.are present, as long as at least one of A, B, C, D, E, F, or a salt thereof is also present.

[0096] The expression "and / or" is to be understood as including both the conjunctive and the disjunctive. For example, "A and / or B" means "A and B" as well as "A or B", and expressly covers examples of one of the two without reference to the other. For example, a composition that comprises "an emulsifier selected from fatty alcohols and / or esters" means that the disclosure includes compositions comprising one or more fatty alcohols or one or more esters, as well as compositions comprising one or more fatty alcohols and one or more esters. As a further example, the disclosure of "methods for styling hair, straightening hair and / or reducing hair frizz" includes methods for styling or methods for straightening hair or methods for reducing hair frizz, as well as methods for styling and straightening hair, methods for styling and reducing hair frizz, etc.

[0097] As used herein, the phrases "and mixtures thereof," "and a mixture thereof," "and a combination thereof," "or mixtures thereof," "or a mixture thereof," "or combinations thereof," and "or a combination thereof," are used interchangeably to indicate that the list of components immediately preceding the phrase, such as "A, B, C, D, or mixtures thereof," means that the component(s) may be selected from A, B, C, D, from A + B, from A + B + C, from A + D, from A + C + D, etc., without limitation on their variations. Thus, the components may be used individually or in any combination thereof.

[0098] For the purposes of this disclosure, it should be noted that, in order to provide a more concise description, some of the quantitative expressions given herein are not qualified by the term “about”. It is understood that, whether the term “about” is used explicitly or not, each quantity given herein is intended to refer to the given actual value, and it is also intended to refer to the approximation to that given value that would be reasonably inferred based on ordinary skill in the art, including approximations due to experimental and / or measurement conditions for that given value. All ranges and quantities stated herein are intended to include subranges and quantities using any disclosed point as a bound. Thus, a range of "1% to 10%, such as 2% to 8%, such as 3% to 5%" is intended to encompass ranges of "1% to 8%", "1% to 5%", "2% to 10%", and so on. All figures, quantities, ranges, etc. are intended to be modified by the term "approximately", whether or not expressly stated. Similarly, a given range of "about 1% to 10%" is intended to have both its 1% and 10% bounds modified by the term "about."The term "approximately" is used herein to indicate a difference of up to + / - 10% from the stated number, such as + / - 9%, + / - 8%, + / - 7%, + / - 6%, + / - 5%, + / - 4%, + / - 3%, + / - 2%, or + / - 1%. Similarly, all bounds of the ranges are understood to be individually disclosed, so that, for example, a range of 1:2 to 2:1 is understood to disclose a ratio of both 1:2 and 2:1.

[0099] Furthermore, unless expressly indicated otherwise or where the context of the disclosure clearly dictates otherwise, the expression "the at least one X may be present in an amount ranging from Y% to Z%" should be understood to mean that the total number of X present in the composition ranges from Y% to Z%, inclusive. For example, "at least one polyphenol may be present in an amount ranging from about 0.01% to about 10%" means that the total amount of polyphenols present ranges from about 0.01% to about 10%, inclusive of 0.01% and 10%.

[0100] "Active ingredient," as used herein with respect to the percentage of an ingredient or raw material, refers to 100% of the activity of the ingredient or raw material.

[0101] All quantities stated herein are relative to the amount of active ingredient unless otherwise stated.

[0102] Unless otherwise indicated, all percentages indicated herein are by weight, relative to the total weight of the composition.

[0103] All percentages, parts and ratios herein are based on the total weight of the compositions of the present disclosure, unless otherwise indicated.

[0104] The term "treat" (and its grammatical variations) are used herein to refer to the application of the compositions of the present disclosure to the surface of the hair.

[0105] As used herein, the expression "applying a composition to the hair", and variations thereof, is intended to mean contacting the hair with at least one of the compositions of the disclosure in any manner. It may also This involves contact with the hair in an effective quantity.

[0106] As used herein, the term "styling" is intended to include "shaping" and "smoothing."

[0107] As used herein, the term "curly hair" refers to any hair having a curl, and "wavy hair" refers to any hair having a wave. The curls and / or waves may be natural or unnatural, i.e., formed by chemical or physical treatment of the hair. The degree of curl and / or wave of the hair may vary and is not limited.

[0108] A "leave-in" composition or product refers to a hair treatment composition that is not rinsed and / or removed with water or an acceptable solvent after the composition is applied to the hair; instead, the composition is left on the hair for a desired period of time, such as 1 hour, 2 hours, 3 hours, 4 hours, up to 8 hours, overnight, or as long as necessary, until the next washing or rinsing of the hair.

[0109] As used herein, the term "polyol" refers to an organic molecule comprising at least two free hydroxyl groups.

[0110] The terms "substantially free" or "essentially free" as used herein mean that the specific material may be used in a manufacturing process in small amounts that do not significantly affect the fundamental and novel characteristics of the compositions according to the disclosure. These terms may also mean that the specific material is not used in a manufacturing process, but may still be present in a starting material included in the composition.

[0111] As used herein, unless expressly stated otherwise, the term "substantially free" or "essentially free" means that the specific material may be present in small amounts that do not materially affect the fundamental and novel characteristics of the compositions according to the disclosure. For example, there may be less than 2% by weight of a specific material added to a composition, based on the total weight of the compositions (provided that an amount less than 2% by weight does not materially affect the fundamental and novel characteristics of the compositions according to the disclosure). Similarly, the compositions may include less than 2%, less than 1.5%, less than 1%, less than 0.5%, less than 0.1%, less than 0.05% or less than 0.01%, or none of the specified material.Any components positively presented in the present disclosure may be negatively excluded from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure. The term "substantially free" or "essentially free" . as used herein may also mean that the specific material is not added to the composition, but may still be present in a raw material included in the composition.

[0112] As used herein, the term "salts" as referred to throughout the disclosure may include salts having a counterion, whether in ionized or non-ionized form. It is to be understood that, with respect to the salts of acids described herein, it is intended to encompass the use of a salt of the acid as an ingredient added to a composition according to the disclosure, or to the salt of the acid that is formed when the acid is used as an ingredient in a composition according to the disclosure (whether in ionized or non-ionized form).

[0129] Add hydrogenated starch hydrolysate to the main tank and mix until uniform.

[0130] Add polyacrylamide (and) C13-14 isoparaffin (and) laureth-7 (SEPIEL 305TM) and mix until uniform. The batch will thicken.

[0131] Add buffers to correct the pH of the mix in the main tank to 3.5-4.5.

[0132] Add tannic acid (dilute in 5% water) and mix until uniform.

[0133] All compositions were in the form of an oil-in-water emulsion. water and had a pH of about 3.5 to about 4.5 at 25°C. The compositions had Brookfield viscosities of about 2,440 cps, measured with a B spindle at 50 rpm for 1 minute under ambient conditions.

[0134] Example 2 - Stability study

[0135] The stabilities of the exemplary inventive compositions 1A and 1B were evaluated over a period of up to two months. The pH values ​​of compositions 1A and 1B were respectively measured at the initial date (day 0) and at the last days of the first week, fourth week and eighth week after the initial date at room temperature (25 °C) and elevated temperature (45 °C). The viscosities of compositions IA and IB were measured respectively at the initial date (day 0) and on the last days of the fourth week and eighth week after the initial date at room temperature (25 °C) and elevated temperature (45 °C) using a Rheomat RM 180 viscometer and a Brookfield viscometer. The appearance of these compositions was also observed and evaluated for any onset of precipitation or separation, an indicator of instability, during this two-month period.

[0136] Table 2 shows the pH values ​​of compositions IA and IB measured over the two months at 25°C and 45°C. A pH represents the change in pH values.

[0140] As can be seen in Tables 2 and 3, at the end of the study, no precipitation or phase separation was observed, only minor non-significant changes in pH and viscosity were noted and only a minor change in color was observed. The results demonstrate that compositions IA and IB were stable.

[0141] Example 3 - In vitro hair strand performance testing

[0142] In vitro hair strand tests were carried out to evaluate the performance of the inventive composition IA in comparison with comparative compositions C1, C2, and C3, as well as water (control) on strands of Caucasian hair with natural curls.

[0143] The tests and evaluation were carried out as described below. First, the hair strands were washed with a commercially available rinse-out shampoo. After shampooing, excess water was squeezed out of the strands. Then, equal amounts of compositions 1A, 1C1, 1C2, 1C3 and water were respectively applied to a separate hair strand at a rate of about 0.15 g of composition per 1 g of hair. Then, ten finger strokes were made on the hair strands to ensure that the compositions were evenly distributed on the hair, followed by three strokes with a comb to comb the hair straight. After combing, the hair strands were evaluated for frizz level and sensory properties, and photographs of the hair strands were taken (time 1, T1). The hair strands were then air-dried at room condition.During drying, the strands were shaken five times to mimic consumer movement. Once the hair was dried, ten finger strokes were made over the hair strands to break the film formed by the compositions on the hair fibers. After the film was broken, the hair was evaluated and scored for stiffness, frizz, and tactile properties, compared to the water-treated hair (control). Photographs of the hair strands were also taken at this time (T2). After the evaluation at T2, the strands were placed in a humidity chamber with 80% relative humidity (RH) at room temperature (25 °C), 80% RH for one hour. The strands were re-evaluated for stiffness and frizz after exposure to the high humidity condition for 30 minutes and 1 hour.Photographs of these hair strands were taken after one hour of exposure under the condition of 80% relative humidity (RH) at room temperature (25°C) (time, T3). The above tests and evaluation were carried out in duplicate, i.e. each composition was tested on two separate hair strands, compared to two separate control hair strands treated with water.

[0144] All property ratings were performed independently by 13 individuals. Stiffness was rated on a scale of 1 to 5, with 1 being the stiffest and 5 being the least stiff. Frizz was also rated on a scale of 1 to 5, with 1 being the least frizz and 5 being the most frizz.

[0145] The appearance of the locks of hair treated with compositions C1-C3 and IA, by compared to the control hair, at times T1, T2 and T3 was illustrated in the photographs in [Fig.l]. As can be seen in [Fig.l], while the hair strands treated with comparative compositions C1-C3 were straighter and with less frizz than the control hair strands, the hair treated with the inventive composition IA was the straightest and with the least frizz. The smoothing and frizz control benefits provided by composition IA lasted even after the hair strands were exposed to a high humidity condition (80% RH) for one hour. Therefore, the smoothing and frizz control benefits provided by composition IA are long-lasting.

[0146] The gradation of the stiffness of the treated hair at time T3 compared to the control was shown in Table 4 and [Fig.2]. The gradation of the frizz of the treated hair at time T3, compared to the control, was shown in Table 5 and [Fig.3]. As shown in Tables 4 and 5 and Figures 2 and 3, the inventive composition IA significantly improved the frizz control and the stiffness of the hair, compared to the comparative compositions C1, C2 and C3.

[0149] Example 4 - In vitro mannequin test

[0150] The performance of compositions with and without fatty alcohols was evaluated on mannequin heads with curly hair. Compositions IC and 1D were used in these tests.

[0151] Photographs of the mannequin heads were taken to show the appearance of the hair at the initial time (T0).

[0152] The mannequin heads were first washed by shampooing, conditioning and rinsing. After the hair was washed, excess water was removed from the hair using a towel and the hair was detangled using a brush. Then, the IC and 1D compositions were respectively evenly applied in sections in an amount of about 5 g / half head to a separate mannequin head while the hair was detangled and still wet. After application, the IC and 1D compositions were left on the hair and the hair was combed to be smooth and then dried using a roller ball at a temperature of about 40-45 °C for about 60 minutes.

[0153] Hair stiffness and frizz were assessed by tactile assessment and visual observation before, during and after treatment. Photographs of the mannequin heads were taken to show the appearance of the hair before treatment (initial time, T0), when the hair was detangled and still wet after application of the compositions (T1), and the final appearance of the treated hair when it was dried (T2). Photographs of the mannequin heads were shown in [Fig.4].

[0154] As shown in [Fig. 4], compositions IC and 1D provided a similar reduction in hair curl. However, compared to hair treated with composition 1D, which includes a fatty alcohol, hair treated with composition IC, which does not include fatty alcohols, had a cleaner, lighter appearance and appeared less coated (waxy).

[0155] Example 5 - In vivo evaluation on consumer hair

[0156] The performance of the IA composition was tested on consumers with wavy to curly hair, with varying hair density (low - high), length (short - long), diameter (fine - coarse) and porosity / sensitivity (low - high).

[0157] Before applying the IA composition, the consumers' hair was washed and conditioned with a commercially available shampoo and light conditioner. After removing excess water from the hair and while the hair was still damp, the IA composition was applied to the consumers' hair according to two different application routines. In the first application routine (routine 1), also referred to as the control routine or standard routine, the IA composition was applied to half of a customer's head in sections, including the hairline, in the manner in which a hairdresser applies a conventional hair color or smoothing composition, and then distributed evenly through the hair by combing it through.In the second application routine (routine 2), i.e., a modified or new routine, the IA composition was applied to the other half of the client's head in a less root-oriented and less sectional manner, as a client usually does, and then spread evenly through the hair by combing it. After application, the hair was air-dried for six hours. Once the hair was dry, fingers were run through the hair to break the film or coating formed on the hair. Before, during, and after the treatment, photographs of the hair were taken from the back of the head, and a tactile appreciation and visual observation of the hair were performed by the hairdressers.

[0158] Figures 5A-5C are photographic images illustrating the appearance of the hair of three consumers before, during, and after treatment using Composition IA via two different application routines, as described above. The hair on the right side of each head was treated with Composition IA via routine Application Routine 1, and the hair on the left side of each head was treated with Composition IA via Routine 2. As can be seen, these consumers had curly hair that varied in degree and density, length, diameter, and sensitivity. TO corresponds to the time before applying Composition IA to the hair; T1 corresponds to the time immediately after applying Composition IA while the hair was still wet; T2 corresponds to the time six (6) hours after applying Composition IA and before film rupture; and T3 corresponds to the time after film rupture.

[0159] As shown in Figures 5A-5C, without heating, hair treated with composition IA was significantly straightened and showed a significant reduction in curls, regardless of how the composition IA was applied to the hair, either via the standard routine or via the new routine. In addition, hair treated with composition IA also demonstrated additional notable properties such as frizz control, detangling, smoothness of the hair, regardless of the composition IA applied. Thus, composition IA can be easily used by a consumer, such as by the exemplified routine 2.

[0160] The above examples demonstrate that the compositions according to the disclosure provide effective temporary smoothing benefits to curly hair, while providing one or more additional sensory benefits such as smoothness and frizz control to the hair. The smoothing effect provided by the compositions according to the present disclosure does not require the use of heat. These various benefits provided by the compositions disclosed herein are long-lasting, even after the hair has been exposed to a high humidity condition, for example, 80% RH for one hour. Furthermore, the compositions according to the disclosure are stable either at room temperature or at an elevated temperature such as 45°C for a period of at least two months.

[0161] It will be apparent to those skilled in the art that various modifications and variations may be made to the compositions and methods according to the disclosure without departing from the spirit and scope of the disclosure. It is therefore intended that the disclosure cover such modifications and variations as well as their equivalents.
