The present disclosure relates to compositions for styling the hair, packaging systems comprising the compositions, and methods of using the compositions.
Conventional hair styling compositions are typically in the forms of lotions, gels, mousses, creams, sprays, serums, wax, oils, clays, etc. It is understood that different forms of compositions can provide different benefits, yet can also present different drawbacks and/or challenges, such as, for example, when the particular composition is applied to hair.
For example, hair gels are a common form for styling compositions for curly hair because they are usually good at providing definition and fighting frizz. However, gels may have a tendency to be thick or have heavy oils mixed in. Thick gels may be too heavy for fine hair and may weigh down the curls of curly hair. In addition, gels may be difficult to apply evenly throughout the hair, and may lead to a “crunchy” sensation on the hair.
Foam compositions, such as mousses, are another form of hair styling composition. There are two types of foam hair styling compositions, aerosol type and non-aerosol type. The aerosol type compositions typically require a propellant and the compositions are usually filled in an aerosol pressure resistant container and are dispensed from the nozzle of the container in the form of a foam. The non-aerosol type hair styling composition does not use a propellant, but the composition is typically filled in a foamer container and produces foam when shear stress is applied, e.g. through a pump. Currently existing non-aerosol hair styling compositions transform a liquid composition to a foam.
As such, there is a need for hair styling compositions that can be easily applied to hair, give good curl definition, provide long-lasting hold, hair manageability, and good cosmetic properties, and/or be environmentally friendly. Ideally, new galenic forms of compositions are desired.
It has now surprisingly been found that compositions according to the disclosure have a unique transformative nature wherein the composition is provided in the form of a gel that can transform into a foam under application of shear stress. These foam compositions can be easy to apply, provide curl definition, and/or may impart various advantageous sensory properties to the hair.
The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate exemplary embodiments of the disclosure, and, together with the general description given above and the description provided herein, serve to explain features of the disclosure.

Compositions according to the disclosure are typically in the form of a gel prior to application of shear stress. The term “gel” is generally understood to mean a soft, semi-solid, or solid-like material that exhibits low to no flow under steady state. A gel can also be understood based on dynamic strain sweep test using a rheometer.
In various embodiments, the gel composition may have the appearance of a traditional gel, and be semi-clear or substantially clear. The viscosity of the gel is not limited, but by way of example only, in certain embodiments the viscosity may range from about 1 to about 25 Pa*s, such as about 3.5 to about 23 Pa*s, about 5 to about 15 Pa*s, about 8 to about 10 Pa*s, or about 9 Pa*s, including all ranges and subranges therebetween, at a shear rate 2 1/s when measured using a rheometer at 25° C. with a 40 mm parallel plate and 1000 μm gap. By way of non-limiting example only, in one embodiment, the viscosity of the gel may range up to about 10 Pa*s, and upon application of shear stress, the viscosity of the composition decreases to less than 0.1 Pa*s and a foam is formed.
In at least certain embodiments, the compositions in gel form may be stable, meaning that no or essentially no phase separation or significant change in pH or viscosity is seen, over a period of at least one week, such as at least one month, at least 6 months, or at least one year under ambient conditions.
Compositions in the form of a gel according to the disclosure are able to transform into a foam (they have decreased viscosity) upon application of sufficient shear stress. For example, mechanical shear stress, such as that which is applied by a pump dispenser, may effect the transformation of the gel to a foam. Other means of applying shear stress, for example shaking the composition, may also cause the gel to transform into a foam.
One way in which foam density is described herein relates to the volume of air bubbles to the total volume of the foam, which includes the bubbles and the liquid carrier thereof. The foam of compositions according to the disclosure may thus comprise air bubbles in at least about 30%, such as at least about 40%, of the foam, and the density may thus be described as at least about 30% or at least about 40% v/v. In various embodiments, the foams may be creamy and/or fine-pored. In certain embodiments, the foam may be sufficiently stable such that it remains substantially foam-like as it is rubbed between the hands and/or worked into the hair. In at least some embodiments, the foam of compositions according to the disclosure may remain stable for more than 5 minutes, such as more than 10 minutes, more than 20 minutes, more than 30 minutes, more than 45 minutes, more than 60 minutes, or more than 90 minutes, without a significant change in volume and/or density.
The foam compositions according to the present disclosure are generally easy to spread throughout the hair, which may improve coverage. The compositions further are able to provide style and/or shaping, and in at least in some embodiments may provide care benefits to hair, especially curly hair. The compositions may also have cosmetic attributes such as curl definition and elongation, as well as frizz control, shine, maintaining hydration of over 8 hours in some cases, ease of styling, no crunch, no build up, fast drying, and/or are not sticky.
II. Packaging Systems
The present disclosure also relates to packaging systems comprising the compositions described herein. The packaging systems comprise at least one container suitable for containing and/or applying the composition and/or transforming the compositions from a gel into a foam.
In various embodiments, a packaging system according to the present disclosure may include a dispensing container containing a composition disclosed herein. The composition contained in the dispensing container is generally transparent or semi-transparent, i.e., clear or semi-clear and in the form of a gel.
Compositions may optionally be in aerosol or non-aerosol form. If they are in aerosol form, the compositions or packaging systems may comprise at least one propellant. If they are in non-aerosol form they do not need a propellant. Instead, they can be packaged in any dispensing container that has a dispensing device configured to dispense its contents as non-aerosol foam with or without controlled amount or doses.
By way of non-limiting example, suitable dispensing container may be any type of non-aerosol foam dispenser container. Such container may including a foaming chamber having a mesh therein and/or a foam distributing nozzle, so called foam pump, pump dispenser, or pump foamer. The dispensing container may have any size or shape and may be made of any suitable material(s).
The dispensing container may be prefilled with a composition according to the disclosure. The dispensing container may also be configured to allow filling or refilling with a composition disclosed herein when the dispensing container is empty or when the composition contained therein is running low, by the user at any time or near the time of use.
III. Methods
The present disclosure also relates to methods for styling keratin fibers, e.g. human hair, using the compositions described herein. The methods generally comprise applying any of the disclosed compositions to the keratin fibers.

In various exemplary embodiments, the methods may include applying a styling- or shaping-effective amount of a foam composition of the present disclosure to hair (wet, damp, or dry hair), before, during, and after styling and shaping the hair. The composition may be left on the hair for any period of time, such as a few hours or a few days, or until the next washing or rinsing of the hair.
In some embodiments, a composition of the disclosure may be applied to the hair and left on the hair, e.g. as a mousse for holding curls or other hair styles. In one embodiment, the hair is allowed to air dry after application of the composition, and is styled or shaped with no heat being applied to the hair. Styling or shaping the hair may involve the use of devices on hair such as a brush, a comb or running the fingers of the hand through the hair. Optionally, styling or shaping can be done using twisting out techniques. In this situation, the composition disclosed herein may be applied to the hair before or during performing twist out, where the hair is twist and then let go to create curls or other hair styles.
In another embodiment, the methods may include styling or shaping the hair with a heating device before, during, or after the compositions are applied to the hair.
Additionally, the compositions provide a variety of desirable sensory benefits to the hair, for example, smoothness without weigh-down, detangling, anti-frizz, softness, moisture, and/or anti-shrinkage. As such, the compositions are useful in styling or shaping hair while also caring for hair, conditioning hair, and/or imparting one or more of smoothness, detangling, and/or frizz control to hair. Accordingly, the instant disclosure encompasses methods for treating hair with the compositions of the instant disclosure. For example, the methods may also include applying the compositions to curly hair to boost volume or hold existing curl styles, as well as providing additional sensory benefits to the hair, e.g. conditioning.
As described herein, due to the transformative texture or transformative nature of the gel compositions, the gel is transformed into a foam when a shear stress is applied to the gel. Thus, the disclosure also relate to methods of transforming gel compositions described herein into foams by applying shear stress to the gel.
Having described the many embodiments of the present invention in detail, it will be apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims. Furthermore, it should be appreciated that all examples in the present disclosure, while illustrating many embodiments of the disclosure, are provided as non-limiting examples and are, therefore, not to be taken as limiting the various aspects so illustrated. It is to be understood that all definitions herein are provided for the present disclosure only.
As used herein, the terms “comprising,” “having,” and “including” (or “comprise,” “have,” and “include”) are used in their open, non-limiting sense. The phrase “consisting essentially of” limits the scope of a claim to the specified materials or steps and those that do not materially affect the basic and novel characteristics of the compositions.
In this application, the use of the singular includes the plural unless specifically stated otherwise. The singular forms “a,” “an,” “the,” and “at least one” are understood to encompass the plural as well as the singular unless the context clearly dictates otherwise. The expression “one or more” means “at least one” and thus includes individual components as well as mixtures/combinations. Likewise, the term “a salt thereof” also relates to “salts thereof.” Thus, where the disclosure refers to “an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or mixtures thereof,” it indicates that 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.
Throughout the disclosure, if the term “a mixture thereof,” or “a combination thereof” including variants, is used, following a list of elements as shown in the following example where letters A-F represent the elements: “one or more elements selected from the group consisting of A, B, C, D, E, F, or mixtures thereof.” The term, “a mixture thereof” does not require that the mixture include 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 a mixture of any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.”
For purposes of the present disclosure, it should be noted that to provide a more concise description, some of the quantitative expressions given herein are not qualified with the term “about.” It is understood that whether the term “about” is used explicitly or not, every quantity given herein is meant to refer to the actual given value, and it is also meant to refer to the approximation to such given value that would reasonably be inferred based on the ordinary skill in the art, including approximations due to the experimental and/or measurement conditions for such given value. All ranges and amounts given herein are intended to include sub-ranges and amounts using any disclosed point as an end point. 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 numbers, amounts, ranges, etc., are intended to be modified by the term “about,” whether or not so expressly stated. Similarly, a range given of “about 1% to 10%” is intended to have the term “about” modifying both the 1% and the 10% endpoints. The term “about” 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%. Likewise, all endpoints of ranges are understood to be individually disclosed, such that, for example, a range of 1:2 to 2:1 is understood to disclose a ratio of both 1:2 and 2:1.
“Active material” as used herein with respect to the percent amount of an ingredient or raw material, refers to 100% activity of the ingredient or raw material.
All amounts given herein are relative to the amount of active material, unless otherwise indicated.
All percentages, parts and ratios herein are based upon the total weight of the compositions of the present disclosure, unless otherwise indicated.
As used herein, the terms “applying a composition onto keratin materials” and “applying a composition onto hair” and variations of these phrases are intended to mean contacting the keratin materials including hair and skin, with at least one of the compositions of the disclosure, in any manner. It may also mean contacting the keratin materials in an effective amount.
Unless otherwise indicated, all percentages herein are by weight, relative to the weight of the total composition.
As used herein, the term “conditioning” means imparting to hair fibers at least one property chosen from combability, moisture-retentivity, luster, shine, and softness. The state of conditioning can be evaluated by any means known in the art, such as, for example, measuring, and comparing, the ease of combability of the treated hair and of the untreated hair in terms of combing work, and consumer perception.
As used herein, the term “efflux” refers to the rate at which a gel composition according to the present disclosure drains out of a cup used for measuring the viscosity of the gel composition. “Efflux time” refers to the time that the composition takes to completely drain out of the cup under the effect of gravity. Typically, higher viscosity corresponds to a longer efflux time.
As used herein, the terms “non-sulfate-based” or “non-sulfate” anionic surfactants means that the surfactant does not comprise a sulfate group.
As used herein, the term “organic” means a material that is produced substantially without or essentially without the use of synthetic materials.
The terms “substantially without” or “essentially without” as used herein means the specific material may be used in a manufacturing process in small amounts that do not materially affect the basic and novel characteristics of the compositions according to the disclosure. The terms may also mean that the specific material is not used in a manufacturing process but may still be present in a raw material that is included in the composition.
As used herein, the term “salts” refers to throughout the disclosure may include salts having a counter-ion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is non-limiting.
As used herein, the term “substantially free” or “essentially free” as used herein means the specific material may be present in small amounts that do not materially affect the basic and novel characteristics of the compositions according to the disclosure. For instance, 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 of less than 2% by weight does not materially affect the basic 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. Furthermore, all components that are positively set forth in the instant disclosure may be negatively excluded from the claims, e.g., a claimed composition may be “free,” “essentially free” (or “substantially free”) of one or more components that are positively set forth in the instant 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 that is included in the composition.
As used herein, the term “sulfate-based surfactant” as used herein, also means “sulfate-containing surfactant.” Thus, the term “essentially free of sulfate-based surfactant” also means “essentially free of sulfate-containing surfactant.”
As used herein, the term “surfactants,” as well as any specifically-identified surfactants, includes salts of the surfactants even if not explicitly stated.
As used herein, the term “surfactant system” refers to a combination of different surfactants. For example, the term “anionic surfactant system” refers to one anionic surfactant or a combination of different anionic surfactants, and the term “nonionic surfactant system” refers to one nonionic surfactant or a combination of different nonionic surfactants.
As used herein, the term “synthetic” means a material that is not of natural origin. The term “natural” and “naturally-sourced” means a material of natural origin, such as derived from plants, which also cannot be subsequently chemically or physically modified. “Plant-based” means that the material came from a plant.
As used herein, the term “transformative texture” or “transformative nature” refers to the texture or nature of compositions according to the disclosure that can be changed from a gel to a foam when a shear stress is applied to the gel.
As used herein, the term “treat” (and its grammatical variations) refers to the application of the compositions of the present disclosure onto the surface of keratin materials, such as hair.
Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not expressly recite an order to be followed by its steps or it is not specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that any particular order be inferred.
The following examples are intended to be non-limiting and explanatory in nature only. In the Examples, amounts are expressed in percentage by weight (wt %) of active materials, relative to the total weight of the composition.
The following inventive gel composition was prepared according to the formulation set forth in Table 1 below.
Inventive Composition 1 was prepared as follows. First, mix the solvents and the hydroxypropyl guar and xanthan gum until all hydroxypropyl guar and xanthan gum were dispersed in the solvents, then, add the rest ingredients except citric acid one at a time and mixing during each addition. After mixing well, check the pH of the composition and adjust the pH to about 4.5 with citric acid.
Inventive Composition 1 was semi-clear to clear and looked like a gel. The gel can transform to stable, semi-transparent foam when a shear stress is applied to the gel. The pH of Inventive Composition 1 was about 3.5 to about 4.5 at 25° C. The viscosity of Inventive Composition 1 was measured by a viscometer Rheomat 180 model at 25° C. with Spindle #2. The measurement was performed after 30 seconds of rotation of the spindle in the composition at a shear rate of 200 rpm. The viscosity can range from 200 cps to 500 cps.
Inventive Composition 1 had a gel-like texture 210 as illustrated in
Inventive Composition 1 in the form of a gel may be stable for at least one year, under ambient conditions. Thus, Inventive Composition 1 in the form of a gel has a Period After Opening (PAO) characteristic of at least one year, which means it may remain stable and safe for human use at least one year after the package containing the composition has first been opened.
A study of the mechanism of texture transformation from gel to foam was performed on Inventive Composition 1, prepared according to the formulation of Table 1, in comparison with five commercially available compositions (C1, C2, C3, C4, and C5), of which composition C1 is a shampoo, composition C2 is a spray hair gel, composition C3 is a traditional hair styling gel, composition C4 is a hair styling foaming liquid, and composition C5 is a hair milk (lotion). The flow property of each sample was characterized using a rheometer (DHR-3, TA instruments, New Castle, Del., USA) with 40 mm parallel plates. The gap between the parallel plates was 1 mm. All tests were conducted at 25° C. and atmospheric pressure. The sample was subjected to shear ramp starting from 0.1 1/s to 1000 1/s within a 300 seconds period. The time interval between data points is 1 second. The shear stress response was recorded for every data point.
A foam study was conduct to evaluate the foaming property of Inventive Composition 1. The result is illustrated in
The study demonstrated that even by hand shaking, Inventive Composition 1 could transform from gel to foam, reaching a density over about 40% v/v. In addition, the foam was very stable with little change to its volume or density, even after 90 minutes.
A comparative study was conducted to evaluate the performance of Inventive Composition 1 in comparison with the commercially available compositions C2 and C5, as described in Example 2. Composition C2 was in the form of a gel and could not transform into foam. Composition C5 was not a gel but was able to foam. In this test, similar amounts of foam or gel of Inventive Composition 1, and compositions C2 and C5 were respectively applied to the same hair (African American Curly Panel) that have curl types VI and VII.
The attributes were assessed and the data showed that, compared to compositions C2 and C5, Inventive Composition 1 received high ratings in curl definition, frizz control, shine, hydration over 8 hours, ease of styling, no crunch, no build up, dries faster, not sticky product, and elongation. Inventive Composition 1 was also found to perform better in providing hair care and styling benefits than composition C2.
It will be apparent to those skilled in the art that various modifications and variations can be made in the compositions and methods according to the disclosure without departing from the spirit or scope of the disclosure. Thus, it is intended that the disclosure cover such modifications and variations and their equivalents.
