CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This patent application claims priority to U.S. Non-Provisional Application No. 16/915,929 filed on June 29, 2020 and French Application No. FR2008542 filed on August 18, 2020. Both of which are incorporated by reference herein in their entireties.

TECHNICAL FIELD

[0002] This patent application claims priority to U.S. Non-Provisional Application No. 16/915,929 filed on June 29, 2020 and French Application No. FR2008542 filed on August 18, 2020. Both of which are incorporated by reference herein in their entireties.

[0003] The present disclosure relates to compositions for treating, caring for, and/or conditioning keratinous substrates, as well as systems and kits comprising the compositions, and methods of using the compositions.

BACKGROUND

[0004] Consumers desire new and improved compositions for treating, caring for, and/or conditioning keratin substances, such as skin or hair. 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, formulation challenges.

[0005] For example, hair care compositions, such as hair conditioner and/or treatment compositions, may be used before or after the hair has been washed with shampoo and/or subjected to a chemical treatment to improve or return to the hair its natural luster, shine, and softness, or to improve the feel, appearance, and manageability of hairs. Traditional hair conditioning or treatment compositions may be rinse-off or leave-on cream-like emulsions or lotions. However, while generally allowing for ease of formulation, certain components in such traditional hair treatment and/or conditioner compositions (e.g. silicones and/or ethanol) may cause build-up on the hair and/or may cause the hair to feel heavy or weighed-down, and/or may not provide sufficient conditioning benefits such as smoothness, shaping, and/or moisture effect. Additionally, the presence of silicones in a composition may present difficulties in preparing the compositions in various formulations, e.g. as an aerosolized foam.

[0006] It is therefore desired to provide new and improved compositions for treating, caring for, and/or conditioning keratin substances, such as skin or hair, which may avoid or minimize formulation challenges yet provide benefits to the keratin substrates to which the compositions are applied.

[0007] It has now surprisingly been found that aerosolized foam compositions described herein provide a treatment, care, and/or conditioning composition that is in the form of a fluid emulsion with low viscosity prior to being aerosolized, which, when aerosolized, forms a compact, dense, and supple foam. Additionally, it has been found that aerosolized foam compositions according to the disclosure are surprisingly and unexpectedly more stable than other hair or skin care aerosol foams, and do not collapse. In addition, the compositions provide improved properties to the keratin substrates relative to traditional care, treatment, and/or conditioning compositions. Optionally, the compositions may be free of ethanol and silicones. The ingredients in the compositions may optionally be sustainable, i.e. of natural and/or organic sourcing.

DESCRIPTION

[0020] The present disclosure relates to compositions comprising at least one vegetable oil, at least one fatty alcohol, at least one cationic conditioning agent, and at least one propellant. The compositions may be in the form of a low-viscosity fluid emulsion prior to being aerosolized, or may be in the form of aerosol foam compositions. The present disclosure further relates to system and kits comprising the compositions, and methods of using the aerosolized foam compositions.

I. Compositions

[0021] The compositions according to the disclosure comprise at least one vegetable oil, at least one fatty alcohol, at least one cationic conditioning agent, and at least one propellant. In certain embodiments, the compositions may be free or substantially free of ethanol and/or silicones.

[0022] In various exemplary and non-limiting embodiments, the compositions may be in the form of a fluid emulsion with low viscosity prior to being aerosolized and when aerosolized, form compact, dense, and/or stable foams that do not collapse and do not look "airy" or "whipped." The aerosolized foam compositions may, in at least some embodiments, impart one or more properties such as ease of distribution, ease of rinsing, suppleness, softness, shine, moisturizing effect, smoothness, conditioning, detangling, shaping, frizz control, discipline, overall feel of the hair, body, volume, fullness, movement, and/or bounce to the hair. The aerosolized foam compositions may, in further embodiments, be useful as hair-color-toning compositions, or as compositions for depositing color onto hair.

Vegetable Oil

[0023] Compositions according to the disclosure comprise at least one vegetable oil. Vegetable oils are oils derived from a plant, for example, oils from seeds or fruits. A high level of vegetable oil, such as an amount of about 1% or higher, is not typically included in traditional emulsion cosmetic compositions because oils at this level may negatively impact the stability of the emulsion cosmetic composition. However, it has been found that including vegetable oil in the compositions according to the disclosure provides increased beneficial conditioning properties to keratinous substrates, and, when combined with other components in the compositions, even at a relatively high concentration, surprisingly and permits aerosolization of the emulsion to provide a stable aerosolized foam composition.

[0024] Vegetable oils that may be used according to the disclosure include, but are not limited to, coconut oil, soybean oil, canola oil, rapeseed oil, corn oil, cottonseed oil, olive oil, palm oil, peanut oil, safflower oil, sesame oil, sunflower oil, linseed oil, palm kernel oil, tung oil, jatropha oil, mustard oil, camelina oil, pennycress oil, castor oil, wheatgerm oil, apricot kernel oil, pistachio oil, poppy oil, pine oil, avocado oil, hazel nut oil, grapeseed oil, colza oil, cade oil, peach kernel oil, coffee bean oil, jojoba oil, and mixtures thereof. In various embodiments, compositions according to the disclosure comprise coconut oil. In further embodiments, compositions according to the disclosure are substantially free of vegetable oils other than coconut oil. Thus, in various embodiments, the at least one vegetable oil may comprise, consist essentially of, or consist of coconut oil.

In certain embodiments, vegetable oil is present in an amount of at least about 0.1% by weight, such as at least about 0.2%, at least about 0.3%, at least about 0.4%, at least about 0.5%, at least about

0.6%, at least about 0.7%, at least about 0.8%, at least about 0.9%, at least about 1%, at least about 1.1%, at least about 1 .2%, at least about 1 .3%, at least about 1 .4%, at least about 1 .5%, at least about 1 .6%, at least about 1 .7%, at least about 1 .8%, at least about 1 .9%, or at least about 2% by weight, such as about 0.1%, about 0.2%, about 0.3%, about 0.4%, about 0.5%, about 0.6%, about 0.7%, about 0.8%, about 0.9%, about 1%, about 1.1%, about 1 .2%, about 1 .3%, about 1 .4%, about 1 .5%, about 1 .6%, about 1 .7%, about 1 .8%, about 1 .9%, or about 2% by weight, relative to the total weight of the composition.

Fatty Alcohol

[0026] Compositions according to the disclosure comprise at least one fatty alcohol. In certain embodiments, the compositions comprise at least two fatty alcohols. The at least one fatty alcohol may, in some embodiments, be chosen from liquid fatty alcohols. In further embodiments, the at least one fatty alcohol may be chosen from combinations of at least one liquid fatty alcohol and at least one solid fatty alcohol.

[0027] As used herein, "fatty alcohol" refers to any alcohol with a carbon chain of C5 or greater, such as, for example, C8 or greater, C10 or greater, and C12 or greater. The fatty alcohols useful according to the disclosure include, but are not limited to, alkoxylated or non-alkoxylated, saturated or unsaturated, linear or branched, fatty alcohols, for example with from 6 to 30 carbon atoms, such as from 8 to 30 carbon atoms.

[0028] As used herein, "alkoxylated fatty alcohol" refers to any fatty alcohol with a carbon chain of C5 or greater, as defined above, further comprising at least one alkoxy group. For example, the at least one alkoxylated fatty alcohol may have a carbon chain of C8 or greater, C10 or greater, and C12 or greater. Further, for example, the at least one alkoxylated fatty alcohol may be chosen from alkoxylated polymers (including co-, ter- and homo-polymers) derived from alcohols such as glycerol (e.g. polyglyceryl derived from four glycerol molecules). The at least one alkoxy group of the at least one alkoxylated fatty alcohol may, for example, be derived from an alkoxylation reaction carried out with alkylene oxide. Non-limiting examples of at least one alkoxylated fatty alcohol include any fatty alcohol comprising at least one polyethylene glycol ether and any fatty alcohol comprising at least one polypropylene glycol ether.

[0029] According to various embodiments, the at least one fatty alcohol is chosen from liquid fatty alcohols, in particular those containing C10-C34, may have branched carbon chains and/or have branched and/or unsaturated (C=C double bond), and contain from 12 to 40 carbon atoms. The liquid fatty alcohols may be represented by the formula R- OH, wherein R denotes a C12-C24 branched alkyl group or an alkenyl group (comprising at least one C12-C24 double bond C=C), R being optionally substituted by one or more hydroxy groups. In some embodiments, the liquid fatty alcohol is a branched saturated alcohol. In at least certain embodiments, R does not contain a hydroxyl group. The liquid fatty alcohol may be chosen from oleic alcohol, linoleic alcohol, linolenic alcohol, isocetyl alcohol, isostearyl alcohol, 2-octyl-1 -dodecanol, 2-butyloctanol, 2-hexyl-1 -decanol, 2- decyl-1 -tetradecanol, 2-tetradecyl-1 -cetanol and mixtures thereof. Preferably, the liquid fatty alcohol is 2-octyl-1 -dodecanol.

[0030] According to further embodiments, the at least one fatty alcohol is chosen from solid fatty alcohols. Solid fatty alcohols that can be used include those that are solid at ambient temperature and at atmospheric pressure (25 °C, 780 mmHg), and are insoluble in water, that is to say they have a water solubility of less than 1% by weight, preferably less than 0.5% by weight, at 25 °C, 1 atm. The solid fatty alcohols may be soluble, under the same temperature and pressure conditions, in at least one organic solvent (for example ethanol, chloroform, benzene or liquid petroleum jelly) to at least 1% by weight.

[0031] The solid fatty alcohols may be represented by the formula R-OH, wherein R denotes a linear alkyl group, optionally substituted with one or more hydroxyl groups, comprising from 8 to 40 carbon atoms, preferably 10 to 30 carbon atoms, more preferably 12 to 24 carbon atoms, and even more preferably 14 to 22 carbon atoms.

[0032] For example, the at least one solid fatty alcohol may be chosen from lauryl alcohol or lauryl alcohol (1 -dodecanol); myristic or myristyl alcohol (1-tetradecanol); cetyl alcohol (1 -hexadecanol); stearyl alcohol (1 -octadecanol); arachidyl alcohol (1 -eicosanol); behenyl alcohol (1 -docosanol); lignoceryl alcohol (1 -tetracosanol); ceryl alcohol (1 -hexacosanol); montanyl alcohol (1 -octacosanol); myricylic alcohol (1 -triacontanol); or mixtures thereof. In some embodiments, the compositions disclosed herein comprise at least one solid fatty alcohol chosen from cetyl alcohol, stearyl alcohol, behenyl alcohol and mixtures thereof such as cetylstearyl or cetearyl alcohol.

[0033] Thus, without intending to be limiting, the at least one fatty alcohol may be chosen from C9-C11 alcohols, C12-C13 alcohols, C12-C15 alcohols, C12-C16 alcohols, C14-C15 alcohols, C12-C22 alcohols, arachidyl alcohol, behenyl alcohol, caprylic alcohol, cetearyl alcohol, cetyl alcohol, coconut alcohol, decyl alcohol, hydrogenated tallow alcohol, jojoba alcohol, lauryl alcohol, myristyl alcohol, oleyl alcohol, palm alcohol, palm kernel alcohol, stearyl alcohol, tallow alcohol, tridecyl alcohol, 2-octyldodecanol, isostearyl alcohol, 2-hexyldecanol, 2-heptyldecanol, 2-octyldecanol, caproic alcohol (1 -hexanol), enanthic alcohol (1 -heptanol), caprylic alcohol (1 -octanol), pelargonic alcohol (1 -nonanol), capric alcohol (1 -decanol), lauryl alcohol (1 -dodecanol), or a mixture thereof. For example, in one embodiment, the at least one fatty alcohol is octyldodecanol.

[0035] The total amount of fatty alcohols, or the amount of each of the individual fatty alcohols, in the composition may range up to about 15%, such from about 0.01% up to about 10% by weight, based on the total weight of the composition. By way of non-limiting example, any of the at least one fatty alcohol may be present in an amount ranging from about 0.01% to about 9%, about 0.01% to about 8%, about 0.01% to about 7%, about 0.01 % to about 6%, about 0.01 % to about 5%, about 0.01 % to about 4%, about 0.01 % to about 3%, about 0.01% to about 2%, about 0.01% to about 1%, or any suitable combination, sub-combination, range, or sub-range thereof by weight, based on the weight of the composition. In further embodiments, the at least one fatty alcohol may be present in an amount ranging from about 0.1% to about 10%, about 0.1% to about 9%, about 0.1% to about 8%, about 0.1% to about 7%, about 0.1% to about 6%, about 0.1% to about 5%, about 0.1% to about 4%, about 0.1% to about 3%, about 0.1% to about 2%, or about 0.1% to about 1% or any suitable combination, sub-combination, range, or sub range thereof by weight, based on the weight of the composition. Thus, any one of the at least one fatty alcohol may be present, by weight, based on the total weight of the composition, from about 0.1 , 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1 , 2, 3, 4, 5, 6, 7, 8, 9 weight percent to about 10 weight percent, including increments and ranges therein and there between.

II. Systems and Kits

[00108] Embodiments of the present disclosure further provide systems and kits comprising any of the compositions described herein. In various embodiments, the systems and kits include an aerosol device containing a low-viscosity composition comprising vegetable oil, at least one fatty alcohol, at least one cationic conditioning agent, and at least one propellant, and a dispensing means for dispensing the content of the container, such as a diffuser or spray device which the user can press to make the product come out. In the aerosol device, the composition is generally in the form of a low-viscosity fluid emulsion, also referred to as a “juice” or “juice phase,” suitable for forming a foam when aerosolized. As such, aerosol devices comprising compositions according to the disclosure are also disclosed.

[00109] Various aerosol devices may be employed for use according to the disclosure. By way of non-limiting example, typical aerosol hair spray devices expel the juice phase in the form of a mist of dispersed droplets. The juice phase is primarily comprised of the hair styling compositions of the instant disclosure, excluding the propellant(s). Small amounts of propellant(s) or other materials from the vapor phase may be added to the juice phase, for example, these components may be partially dispersed or solubilized in the juice phase. Likewise, the vapor phase is primarily comprised of propellant(s). Small amounts of juice phase (or components of the juice phase) may be present in the vapor phase to the extent that the juice phase (or components of the juice phase) are dispersed or solubilized in the vapor phase. In systems and kits according to the disclosure, the aerosol device may be any type of container or canister that is configured to dispense its liquid contents as a foam. Such container or canister may be in any size, color, or shape. For example, a system or kit as disclosed herein may be any container or a canister containing a composition according to the disclosure, and equipped with a nozzle designed to aerosolize the composition to form a foam. The container or canister may have a button to trigger or control dispensing the aerosol contained therein. The aerosol containers may also be made of any materials suitable for cosmetic use.

[00110] The total amount of propellant used in an aerosol device according to the disclosure may vary. In some cases, an aerosol device may include propellant in an amount ranging from about 1% to about 95%, based on the total weight of the hair compositions and propellant (i.e., the total weight of the content inside the aerosol device). In some cases, the total amount of propellant may be about 1% to about 90%, about 1 % to about 50%, about 1 % to about 20%, about 5% to about 90%, about 5% to about 50%, or about 5% to about 20% by weight. For example, the aerosol device may include propellant in an amount of about 5%, such as about 6%, and juice phase in an amount of about 95%, such as about 94%, based on the total weight of the juice phase and propellant.

[00111] Kits according to the disclosure may comprise an aerosol device as disclosed herein. For example, a kit may comprise an aerosol device containing a low-viscosity composition comprising vegetable oil, at least one fatty alcohol, at least one cationic conditioning agent, and at least one propellant. In various embodiments, a kit may comprise an aerosol device comprising a composition according to the disclosure, and one or more skin or hair treatment compositions housed in a separate container. For example, the one or more hair treatment compositions housed in a separate container may include but are not limited to a hair-treatment rinse, a shampoo, a hair-color-toning composition, a hair lightening composition, a hair coloring composition, a hair relaxing composition, a hair straightening composition, or a hair waving composition.

[00112] Methods according to the disclosure comprise treating, caring for, or conditioning keratin substrates with the compositions described herein. The methods generally comprise applying any of the disclosed compositions to the keratin substrates, e.g. to the hair or skin, and optionally subsequently rinsing the compositions. [00113] By way of non-limiting example, the methods may include use of the compositions as a hair conditioner, a pre- or post-treatment for hair, a rinse-off or leave- on mask treatment for hair, or the like. For example, the composition may be a wash-out or leave-on hair conditioner, and the methods may be directed to conditioning the hair by applying the aerosolized compositions to the hair. As further examples, the methods may include use of the compositions as a toning rinse-off or leave-on mousse for hair color.

[00114] Without limitation, methods of treating hair according to the disclosure may include applying an aerosol foam composition according to the disclosure to hair (wet, damp, or dry hair), allowing the composition to remain on the hair for a desired amount of time, and optionally rinsing the composition from the hair. The composition may be applied to the hair before, during, or after other hair compositions (e.g., a shampoo, a conditioner, a mask, a cream, a lotion, a gel, any other chemical treatment, etc.). If desired, the hair may be heated while the composition is on the hair.

[00115] In yet further embodiments, the methods may include using the compositions disclosed herein for skin care or treatment. In some embodiments, the methods include using compositions disclosed herein for cleansing, caring for, or moisturizing skin. The methods may include applying an aerosol foam composition according to the disclosure to skin, allowing the composition to remain on the skin for a desired amount of time, and optionally rinsing the composition from the skin.

[00116] When using the compositions as a rinse-off composition, the composition may be allowed to remain on the keratin substrate (e.g. skin or hair) for any desired amount of time, for example from about a few seconds (e.g. about 10, 20, or 30 seconds) to about 1 , 2, 3, 5, 10, 20, or 30 minutes, or longer.

[00117] 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 invention defined in the appended claims. Furthermore, it should be appreciated that all examples in the present disclosure, while illustrating many embodiments of the invention, 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.

[00118] 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.

[00119] 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.

[00120] Throughout the disclosure, if the term “a mixture 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.”

[00121] 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. [00122] "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.

[00123] As used herein, the terms "applying a composition onto keratin fibers" and "applying a composition onto hair" and variations of these phrases are intended to mean contacting the keratin fibers or hair, with at least one of the compositions of the invention, in any manner. It may also mean contacting the keratin fibers or hair in an effective amount

[00124] Unless otherwise indicated, all percentages herein are by weight, relative to the weight of the total composition.

[00125] As used herein, “cosmetic composition” encompasses many types of compositions for application to keratinous materials such as skin or hair, for example, hair lotions, hair creams, hair gel creams, hair conditioners, hair masques (masks), etc., which can be used either as leave-on or rinse-off treatments or products.

[00126] As used herein, the term "organic" means a material that is produced substantially without or essentially without the use of synthetic materials. The term “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 term “substantially without” or “essentially without” as used herein 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.

[00127] As used herein, the “salts” referred 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.

[00128] 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.

[00129] As used herein, the term “surfactants” includes salts of the surfactants even if not explicitly stated. [00130] As used herein, the term "synthetic" means a material that is not of natural origin. The term "natural" means a material of natural origin, such as derived from plants, which also cannot be subsequently chemically or physically modified.

EXAMPLES

[00131] 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.

Example 1 - Hair Conditioner Compositions

[00132] Three inventive hair compositions and two comparative hair compositions were prepared according to the formulations set forth in Table 1 below.

Table 1

[00133] Each of Compositions 1 A-1 E was prepared by adding the solvent and stirring, then adding the acid to obtain a first mixture, which was then heated. Once the first mixture reached a temperature of about 70-75 °C, the fatty alcohols, cationic conditioning agents, coconut oil, glycols, and additional components were added to the first mixture to obtain a second mixture, which was homogenized at about 1500-2000 RPM for about 10 minutes and then cooled to room temperature. Once the second mixture was cooled to room temperature, optional ingredients were added to obtain a finished bulk of mixture. Finally, for Compositions 1A-1 C, the propellants were added and the composition was aerosolized.

[00134] Inventive Compositions 1A-1 C were low-viscosity compositions which were easily aerosolized into dense, smooth, luxurious, stable foams. This can be seen in the photographic image in FIG. 1 , which is the hair-color-toning foam prepared in Example 1 C.

Example 2 - Comparison of Properties of Compositions and Treated Hair

[00135] A comparative study was conducted to demonstrate the properties and performance of aerosol foam compositions according to the disclosure. After Composition 1A was aerosolized to form a foam hair conditioner, it was tested and compared with the non-aerosolized hair conditioner Composition 1 D in a salon half-head study performed on the hair of 10 volunteers. The hair of the volunteers was medium to long in length, having average diameter, curl pattern of 1 -3, and sensitized level of 3-4.

[00136] The hair of the volunteers was first cleansed with a commercially available shampoo. While the hair was still damp, an amount of Composition 1A needed to condition the hair was applied to one-half of the head of hair and distributed evenly with fingers. The same amount of Composition 1 D was then applied to the other half of the head of hair and distributed evenly with fingers. Both Compositions 1A and 1 D were allowed to remain on the hair for about 5 minutes. After rinsing the compositions from the hair, the hair was combed, dried, and styled.

[00137] During application, Composition 1A was rated better for consistency, melting sensation in hands, coating effect, and absorption than Composition 1 D.

[00138] During and after combing, drying, and styling the hair, the hair treated with Composition 1 A was rated better for surface effect, dry end results, smooth hair feel, ease of shaping, and dryness than Composition 1 D.

[00139] In general, when compared to the comparative non-aerosolized conditioner composition, the aerosolized foam conditioner composition according to the disclosure had better application properties and left hair with improved sensorial properties than the comparative non-aerosolized composition.

[00140] FIG. 2 is a photographic image showing the foam 210 formed by Composition 1 A after being aerosolized in comparison with the cream conditioner 220 of Composition 1 D in a similar amount. As seen in FIG. 2, the foam 210 formed by Composition 1A is compact and dense and does not collapse. The foam 210 also does not look “airy” or “whipped,” and is surprisingly stable.

Example 3 - Properties of Aerosol Compositions Comprising Vegetable Oil

[00141] As described, high levels of vegetable oil are not typically included in traditional emulsion cosmetic compositions. Therefore, a comparative study was conducted to demonstrate the impact of including vegetable oil in the disclosed aerosol foam compositions.

[00142] The study was done by comparing the appearance and rheological characteristics of two compositions prepared based on the same formulation, with the only difference being whether or not vegetable (coconut) oil was included. Composition 1A in Table 1 was compared with a comparative composition including all the same ingredients except coconut oil (Composition 1 A’). In Composition 1 A’, the coconut oil was replaced with the same amount of water. [00143] The viscosities of Compositions 1A and 1A’, as emulsions, were measured using a Rheomat 180 viscometer at about 25°C/spindle 2 (Composition 1A, 320) or 3 (Composition 1 A’, 310) for 30 seconds. The viscosity of Composition 1 A was found to be within a range of about 10 to about 30 DU (“Deflection Units”) when measured at about 25^SC, 200 RPM, 30 seconds on a spindle 2 of the viscometer. The viscosity of Composition 1 A’ was found to be at least about 10 DU when measured at 25^SC, 200 RPM, 30 seconds on a spindle 3 of the viscometer, which indicates an increase in thickness.

[00144] A comparison of Compositions 1 A and 1A’ prior to being aerosolized is shown in FIG. 3. As can be seen, Composition 1A, 320 is noticeably less viscous than Composition 1A’, 310. This difference suggests that Composition 1A’, which is thicker, will be more difficult to aerosolize, while Composition 1A is more fluid, indicating that it will be aerosolized more easily. Without coconut oil, Composition 1A’ resulted in a product that was too thick and could not be aerosolized into a viable product, and could not be dispensed properly.

[00145] This comparison thus demonstrated the benefit of using vegetable oil in aerosol foam compositions according to the disclosure.

Example 4 - Comparison to Compositions with Silicones

[00146] A comparative study was conducted to demonstrate that silicone-based compositions, such as high silicone hair masks, do not aerosolize well. Two exemplary compositions were prepared by mixing the ingredients according to the formulations set forth in Table 2 below. Table 2

[00147] The viscosities of Compositions 4A and 4B were measured using a Rheomat 180 viscometer at about 25 °C for 30 seconds at 200 RPM on a spindle 3 of the viscometer. Both Compositions 4A and 4B have a viscosity range of about 30-85 DU on the Spindle 3. Such viscosity and combination of raw materials impeded the compositions’ ability of actuating effortlessly into a stable, compact foam. The compositions could not be aerosolized well.

Example 5 - Evaluation of Stability of Aerosolized Foams

[00148] An evaluation was performed to study the stability of a foam conditioner composition according to the disclosure (Composition 1A in Table 1) (“Inventive Foam”), relative to a commercially available foam conditioner (“Comparative Foam”) having the following components: Table 3

[00149] The study was conducted by dispensing approximately equal amounts of conditioner compositions to form foams, and observing the behavior of the foams for a period of time. As can be seen in FIG. 4A, at time (t) = 0, i.e. immediately after aerosolization, the Inventive Foam 410 is compact, dense, and holds its shape, while the Comparative Foam 412 is airy and already starting to collapse. In FIG. 4B, at t = 10 minutes, i.e. 10 minutes after aerosolization, the Inventive Foam 410 is still dense, whereas the Comparative Foam 412 is starting to lose its properties as a foam. In FIG. 4C, at t = 30 minutes, Comparative Foam 410 is essentially unchanged, while Comparative Foam 412 continues to lose its foam properties. The photographs in FIGS. 4D (t = 45 minutes) and 4E (t = 60 minutes) demonstrate that the Inventive Foam 410 maintains is shape and appears dense even after one hour, whereas the Comparative Foam 412 continued to dissolve and lose its characteristics as a foam.

[00150] This Example demonstrates that the foam compositions according to the disclosure are stable compared to similar conventional foam products.

[00151] 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.
