The instant disclosure relates to hair cosmetic compositions providing a unique sensorial experience. Additionally, aspects of the disclosure are related to hair cosmetic compositions that provide conditioning and other benefits to the hair.
Many consumers desire to use cosmetic and care compositions that enhance the appearance of keratinous substrates such as hair, e.g., by changing, style, shape, and/or by imparting various cosmetic properties to hair. Different types of hair styling products have been developed by manufacturers that aim to help consumers achieve a desired look, including stylized hair that is long-lasting. Such hair styling products are typically provided in a variety of physical forms, such as liquid, gel, mousse, or pomade, depending on the composition, styling/setting performance, consumer acceptance, branding, and marketing, amongst other variables. Many traditional hair styling products ignore and, sometimes, even reduce desired hair properties, such as sleekness, shine, amount of conditioning, closed-ends, and the like.
While different technologies and products exist in the market for hair styling products, there is still a need for improvement in these areas as well as at the same time, the need to provide caring benefits that are not typically found in a styling product.
Aspects of the instant disclosure relate to hair cosmetic compositions providing a unique sensorial experience. The hair cosmetic compositions are typically formulated to include specific ingredients in certain amounts and ratios that enable the hair cosmetic compositions provide a unique sensor experience, such as an increase in viscosity with the addition of extraneous water.
Additionally, certain embodiments of the disclosure provide hair cosmetic compositions in the form of a lotion that transforms into an oil before or during application of the hair cosmetic compositions onto hair. For instance, as the user rubs, spreads, and/or shears the hair cosmetic composition on dry or wet hand(s) or applies the composition directly to dry or wet hair (e.g., by rubbing, spreading and/or massaging the lotion on the hair fibers), the lotion transforms into an oil. Without being limited to any specific theory, it is believed that the shear stress associated with the application of the hair cosmetic compositions after extraneous water has been added to the hair cosmetic composition breaks the emulsion associated with the hair cosmetic composition to, at least partly, contribute to the transformation of the hair cosmetic composition from a lotion to an oil. Accordingly, in some instances, the transformation of the hair cosmetic composition from a lotion to an oil refers to the hair cosmetic composition transforming from having rheological properties and/or a tactile feel associated with a lotion to having rheological properties and/or a tactile feel associated with an oil. The inventor's surprisingly discovered that the transformation of the hair cosmetic compositions from a lotion to an oil deposits certain ingredients to the user's hair and scalp to provide enhanced benefits, such as conditioning benefits, moisturized scalp, enhanced hair shine, improved curl definition, etc.

It should be understood that the various aspects are not limited to the arrangements and instrumentality shown in the drawings.
Aspects of the instant disclosure relate to hair cosmetic compositions providing a unique sensorial experience. The hair cosmetic compositions are typically formulated to include specific ingredients in certain amounts and ratios, such that the hair cosmetic compositions provide a unique sensor experience. For example, certain embodiments of the disclosure provide hair cosmetic compositions in the form of a lotion that transforms into an oil during application of the hair cosmetic compositions. Additionally, the hair cosmetic compositions may be formulated, such that their viscosity initially increases with the addition of extraneous water. Accordingly, in some embodiments, the hair cosmetic compositions provide the unique sensor experience of a lotion that has its viscosity increase when combined with extraneous water and, subsequently, transforms from a lotion to an oil, which may include a drop in the viscosity of the composition. For instance, the initial increase in viscosity may provide a luxurious feel before the emulsion of the hair cosmetic composition breaks as measured by the drop in viscosity during stress/application (e.g., during a transformation from a lotion to an oil).
The hair cosmetic compositions, according to an aspect of the disclosure, typically comprises:
(a) about 4 to about 32 wt. % of two or more polyols comprising:
(b) about 0.5 to about 10 wt. % of a nonionic surfactant;
(c) about 5 to about 25 wt. % of a fatty ester;
(d) about 0.1 to about 7 wt. % of a film former;
(e) about 0.1 to about 5 wt. % of a thickening agent;
(f) about 0.5 to about 7 wt. % of an oil; and
(g) water,
The hair cosmetic compositions may be formulated to be a leave-in composition or a rinse-off composition. As noted above, the hair cosmetic compositions preferably transform from being in the form of a lotion to an oil during application of the hair cosmetic composition to the user's hair. In some instances, the transformation of the hair cosmetic composition from a lotion to an oil refers to the hair cosmetic composition transforming from having rheological properties and/or a tactile feel associated with a lotion to having rheological properties and/or a tactile feel associated with an oil.
Extraneous water may be added to the hair cosmetic composition before, during, and/or after application of the hair cosmetic composition to the hair. For instance, as the user adds extraneous water to the hair cosmetic composition and applies (e.g., by rubbing, spreading and/or massaging) the hair cosmetic composition to hair, the hair cosmetic composition transforms from a lotion to an oil. In some cases, the viscosity of the cosmetic composition increases when combined with extraneous water in an amount such that the weight ratio of hair cosmetic compositions to extraneous water is about 1:0.5 to about 1:10, about 1:0.6 to about 1:10, about 1:0.7 to about 1:10, about 1:0.8 to about 1:10, about 1:0.9 to about 1:10, about 1:1 to about 1:10; about 1:0.5 to about 1:8, about 1:0.6 to about 1:8, about 1:0.7 to about 1:8, about 1:0.8 to about 1:8, about 1:0.9 to about 1:8, about 1:1 to about 1:8; about 1:0.5 to about 1:6, about 1:0.6 to about 1:6, about 1:0.7 to about 1:6, about 1:0.8 to about 1:6, about 1:0.9 to about 1:6, about 1:1 to about 1:6; about 1:0.5 to about 1:4, about 1:0.6 to about 1:4, about 1:0.7 to about 1:4, about 1:0.8 to about 1:4, about 1:0.9 to about 1:4, about 1:1 to about 1:4; about 1:0.5 to about 1:2, about 1:0.6 to about 1:2, about 1:0.7 to about 1:2, about 1:0.8 to about 1:2, about 1:0.9 to about 1:2, about 1:1 to about 1:2, or any ranges or subranges therebetween.
The viscosity of the hair cosmetic composition typically increase upon contact with water as the hair cosmetic composition transforms from a lotion to an oil. For example, the hair cosmetic composition may have a viscosity of about 10 to about 500 Pas, as measured at a temperature of 25° C. using a rheometer (DHR-2, TA instruments, New Castle, Del., USA) and 40 mm parallel plate geometry with shear rate at a range of 1 to 10 1/s. In some instances, the viscosity of the hair cosmetic composition, when in the form of a lotion, has a viscosity of about 10 to about 500 Pa·s, about 20 to about 500 Pa·s, about 40 to about 500 Pa·s, about 60 to about 500 Pa·s, about 80 to about 500 Pa·s, about 100 to about 500 Pa·s, about 200 to about 500 Pa·s, about 10to about 300 Pa·s, about 20 to about 300 Pa·s, about 40 to about 300 Pa·s, about 60 to about 300 Pa·s, about 80 to about 300 Pa·s, about 100 to about 300 Pa·s, about 1500 to about 300 Pa·s; about 10 to about 100 Pa·s, about 20 to about 100 Pa·s, about 40 to about 100 Pa·s, about 60 to about 100 Pa·s, about 80 to about 100 Pa·s, as measured at a temperature of 25° C. using a rheometer (DHR-2, TA instruments, New Castle, Del., USA) and 40 mm parallel plate geometry with shear rate at a range of 1 to 10 1/s. Preferably, viscosity of the hair cosmetic composition, after transforming to an oil, is less than when the hair cosmetic composition is in the form of a lotion. As noted above, in some instances, the transformation of the hair cosmetic composition from a lotion to an oil refers to the hair cosmetic composition transforming from having rheological properties and/or a tactile feel associated with a lotion to having rheological properties and/or a tactile feel associated with an oil. Without being limited to any specific theory, it is believed that certain hair cosmetic compositions exhibit an increase in viscosity in response to the addition of extraneous water and then exhibit a drop in viscosity due to the emulsion of the hair cosmetic composition breaking from the shear stress, e.g., associated with the application of the hair cosmetic composition or rubbing by the hands of the user.
The viscosity of the hair cosmetic composition, after transforming to an oil, has a viscosity of about 0.01 to about 10 Pa·s, as measured at a temperature of 25° C. using a rheometer (DHR-2, TA instruments, New Castle, Del., USA) and 40 mm parallel plate geometry with shear rate at a range of 1 to 10 1/s.

Nonionic Surfactant(s)
The hair cosmetic compositions include one or more nonionic surfactant(s) in an amount typically ranging from about 0.5 to about 10 wt. %, based on the total weight of the hair cosmetic composition. The total amount of nonionic surfactants can vary but is typically about 0.5 to about 10 wt. %, about 0.5 to about 9 wt. %, about 0.5 to about 6 wt. %, about 0.5 to about 5 wt. %, about 0.5 to about 4 wt. %, about 0.5 to about 3 wt. %, about 0.5 to about 2 wt. %; about 0.75 to about 10 wt. %, about 0.75 to about 9 wt. %, about 0.75 to about 6 wt. %, about 0.75 to about 5 wt. %, about 0.75 to about 4 wt. %, about 0.75 to about 3 wt. %, about 0.75 to about 2 wt. %; about 1 to about 10 wt. %, about 1 to about 9 wt. %, about 1 to about 6 wt. %, about 1 to about 5 wt. %, about 1 to about 4 wt. %, about 1 to about 3 wt. %, about 1 to about 2 wt. %, including ranges and subranges therebetween, based on the total weight of the hair cosmetic composition.
Examples of suitable nonionic surfactants in the present disclosure are those that also function as emulsifier (“nonionic emulsifying surfactants”). nonionic emulsifying surfactants. The nonionic surfactant may have an HLB (hydrophilic-lipophilic balance) ranging from 1 to 7.9 or greater than or equal to 8.
“HLB” refers to the “hydrophilic-lipophilic balance” associated with nonionic surfactants or emulsifiers. In particular, “HLB” value relates to the ratio of hydrophilic groups and lipophilic groups in emulsifiers, and also relates to solubility of the emulsifiers. Lower HLB emulsifiers (such as those with HLB values of 1-7.9) are more soluble in oils (lipophilic material) and are more appropriate for use in water-in-oil (W/O) emulsions. Higher HLB emulsifiers (such as those with HLB values above 8) are more soluble in water (hydrophilic material) and are more appropriate for oil-in-water (O/W) emulsions.
In an embodiment, the suitable nonionic surfactants in the present disclosure have an HLB (hydrophilic-lipophilic balance) of less than 8.
Examples of nonionic surfactants with an HLB of less than 8, include, but are not limited to, sucrose distearate, polyglyceryl-4 isostearate (and) cetyl PEG/PPG 10/1 dimethicone (and) hexyl laurate, sorbitan stearate, octyldodecyl xyloside, glyceryl stearate, PEG-30 dipolyhydroxystearate and combinations thereof.

Non-limiting examples of preservatives include sodium benzoate, potassium sorbate, phenoxyethanol, salicylic acid, tocopherol, chlorphenesin, BHT, disodium EDTA, pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate, and mixtures thereof.
Water
The hair cosmetic composition typically includes 50 wt. % or more of water. For example, the amount of water present in the hair cosmetic composition prior to combination with extraneous water may be about 50 wt. % or more, about 55 wt. % or more, about 60 wt. % or more, about 65 wt. % or more, about 70 wt. % or more, about 75 wt. % or more, about 80 wt. % or more, about 85 wt. % or more, or about 90 wt. % or more, based on the total weight of the hair cosmetic composition. Additionally or alternatively, the hair cosmetic compositions may have about 95 wt. % or less, about 90 wt. % or less, about 85 wt. % or less, about 80 wt. % or less, about 75 wt. % or less, based on the total weight of the hair cosmetic composition. In some embodiments, the hair cosmetic compositions have an amount of water that is about 50 to about 90 wt. %, about 60 to about 90 wt. %, about 63 to about 85 wt. %, about 65 to about 85 wt. %, about 67 to about 83 wt. %, about 70 to about 80 wt. %, or about 71 to about 79 wt. %, including ranges and subranges therebetween, based on the total weight of the hair cosmetic composition.
The methods of styling hair using the hair cosmetic compositions disclosed herein typically comprise:
The hair cosmetic composition may be applied to and dispersed throughout the hair by hand, using a comb/brush, or using any other suitable means. Extraneous water may be combined with the hair cosmetic composition before, during, or after application of the hair cosmetic composition to the hair. In certain instances, as the hair cosmetic composition becomes mixed or placed in contact with extraneous water, the hair cosmetic composition transform from a lotion to an oil. In certain other instances, as the hair cosmetic composition is sheared or rubbed between dry or wet hand or applied directly to hair by rubbing or shearing or spreading or massaging onto the hair and/or scalp, the hair cosmetic composition transforms from a lotion to an oil. As noted above, in some instances, the transformation of the hair cosmetic composition from a lotion to an oil refers to the hair cosmetic composition transforming from having rheological properties and/or a tactile feel and/or visual appearance associated with a lotion to having rheological properties and/or a tactile feel and/or visual appearance associated with an oil.
The extraneous water may be combined with the hair cosmetic composition directly from a source, such as a shower, bath, sink, hose, and/or the like, or indirectly from a source, such as from wet or damp hands, wet or damp skin, wet or damp hair, and/or the like. The user may then physically manipulate the applied hair cosmetic composition (for example, by rubbing the hands together or rubbing the composition against another part of the body such as the head, hair, etc.). In some instances, the transformation from a lotion to an oil occurs automatically without the need for mixing and/or shear. In other words, the hair cosmetic composition becomes sufficiently combined with extraneous water by simply coming into contact with the extraneous water. In some instances, however, a minimal amount of mixing and/or shear may be needed, and may be encouraged. Additionally, the hair may be styled using any suitable means to obtain desirable hairstyles.
The methods for producing a hair cosmetic composition as disclosed herein typically comprise:
wherein the hair cosmetic composition comprises:
wherein the hair cosmetic composition is an emulsion before application to hair and is an oil after application to hair, and all weight percentages are based on the total weight of the hair cosmetic composition.
The methods for producing a hair cosmetic composition as described herein may utilize any suitable equipment, such as standard equipment for mixing, homogenizing, heating, storing, cooling, and the like, used for producing cosmetic products. The present disclosure also envisages kits and/or prepackaged materials suitable for consumer use containing one or more compositions according to the description herein. The packaging and application device for any subject of the invention may be chosen and manufactured by persons skilled in the art on the basis of their general knowledge, and adapted according to the nature of the composition to be packaged. For example, the type of device to be used can be in particular linked to the consistency of the composition, in particular to its viscosity; it can also depend on the nature of the constituents present in the composition, such as the presence of volatile compounds.
In accordance with at least one embodiment of the disclosure, provided is a hair cosmetic composition including
According to further embodiments of the disclosure, provided is a method of styling hair comprising:
In yet further embodiments of the disclosure, provided is a method for producing a hair cosmetic composition comprising:
The terms “comprising,” “having,” and “including” are used in their open, non-limiting sense. The terms “a” and “the” are understood to encompass the plural as well as the singular. The compositions and methods of the present disclosure can comprise, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful.
All percentages, parts and ratios herein are based upon the total weight of the compositions of the present disclosure, unless otherwise indicated. All ranges and values disclosed herein are inclusive and combinable. The expression “inclusive” for a range of concentrations means that the limits of the range are included in the defined interval. For examples, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value to derive a sub-range, etc. Furthermore, all ranges provided are meant to include every specific range within, and combination of sub ranges between, the given ranges. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as sub ranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.
Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about,” meaning within +/−5% of the indicated number.
As used herein, the expression “at least one” is interchangeable with the expression “one or more” and thus includes individual components as well as mixtures/combinations.
The term “substantially free” or “essentially free” as used herein means that there is less than about 5% by weight of a specific material added to a composition, based on the total weight of the compositions. Nonetheless, the compositions may include less than about 2 wt. %, less than about 1 wt. %, less than about 0.5 wt. %, less than about 0.1 wt. %, less than 0.01 wt. %, or none of the specified material.
The term “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.
Throughout the disclosure, the term “a mixture thereof” may be 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, and a mixture 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.”
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, and a mixture 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. The salts referred to throughout the disclosure may include salts having a counter-ion such as an alkali metal, alkaline earth metal, or ammonium counter-ion. This list of counter-ions, however, is non-limiting.
“Volatile”, as used herein, means having a flash point of less than about 100° C. “Non-volatile”, as used herein, means having a flash point of greater than about 100° C.
The term “polymers,” as defined herein, include homopolymers and copolymers formed from at least two different types of monomers.
The term “INCI” is an abbreviation of International Nomenclature of Cosmetic Ingredients, which is a system of names provided by the International Nomenclature Committee of the Personal Care Products Council to describe personal care ingredients.
All components and elements positively set forth in this disclosure can be negatively excluded from the claims. In other words, the compositions (nanoemulsions) of the instant disclosure can be free or essentially free of all components and elements positively recited throughout the instant disclosure.
Some of the various categories of components identified may overlap. In such cases where overlap may exist and the composition includes both components (or the composition includes more than two components that overlap), an overlapping compound does not represent more than one component. For example, a fatty alcohol may be characterized as both a nonionic surfactant and a fatty compound. If a particular composition includes both a nonionic surfactant and a fatty compound, a single fatty alcohol will serve as only the nonionic surfactant or as only the fatty compound (the single fatty alcohol does not serve as both the nonionic surfactant and the fatty compound).
All publications and patent applications cited in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications or patent application incorporated herein by reference, the present disclosure controls.

The rheological properties of Example Composition C were measured using a rheometer (DHR-2, TA instruments, New Castle, Del., USA) and 40 mm parallel plate geometry. The 1 mm gap between the parallel plates was chosen. 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 second period. The time interval between data points is 1 s. The shear stress response was recorded for every data point.
Notably, the viscosity of the diluted sample of Example Composition C was greater than the viscosity of the sample of Example Composition C. A graph illustrating the viscosities of the sample of Example Composition C and the diluted sample of Example Composition C as the shear rate was increased is shown in
Additionally, the sample of Example Composition C and the diluted sample of Example Composition C was imaged before shearing such samples. As seen in
Example Composition C was evaluated in comparison to a Comparative Composition 3 (Comp. 3). About 8 gram samples each of Example Composition C and Comparative Composition 3 were applied to a manikin's hair. The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition C was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 3 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition C was easier to distribute onto the hair than Comparative Composition 3. Example Composition C also appeared and felt lighter than Comparative Composition 3. Additionally, Example Composition C absorbed into the hair easily and elongated the hair. Conversely, Comparative Composition 3 applied like a cream and took more time to apply to the hair than Example Composition C. While Comparative Composition 3 enabled easy detangling of the hair, the hair felt heavier with Comparative Composition 3 than Example Composition C.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition C felt light and more natural than the section of hair that received Comparative Composition 3. Example Composition C also dried faster than Comparative Composition 3. Example Composition C individualized the curls and left the hair shinier than Comparative Composition 3. Specifically, Comparative Composition 3 elongated and clumped the curls in comparison to Example Composition C.
Example Composition F was evaluated in comparison to a Comparative Composition 4 (Comp. 4). 8 gram samples of Example Composition F and Comparative Composition 3 were applied to a manikin's hair. The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition F was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 3 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition F exhibited better slip, a more substantive feel on the hand, easier styling the hair, and easier pick up of the curls. Additionally, Example Composition F absorbed into the hair easily. While Comparative Composition 4 was lightweight, Comparative Composition 4 took more effort to uniformly distribute onto the hair and was harder to form curls as compared to Example Composition F.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition F had a conditioned feel, was lightweight, and had a powdery coating feel with slip. Example Composition F provided more defined curls, better-aligned fibers, and more shine than Comparative Composition 4. The section of hair that received Comparative Composition 4 had a dry feel and did not have defined curls.
Example Composition F was evaluated in comparison to a Comparative Composition 5 (Comp. 5), which is a commercially available product. The list of ingredients for Comparative Composition 5 is provided below:
The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition F was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 5 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition F was easier to distribute on the hair and felt lighter than Comparative Composition 5. Additionally, Example Composition F melted quickly into the hair and provided curls with a bouncy feel. Comparative Composition 5 had a very thick feel on the evaluator's hands and felt heavy on the hair. Comparative Composition 5 also took longer to uniformly distribute onto the hair, was harder to detangle, and elongated the curls in comparison to Example Composition F.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition F had more defined curls and better fiber alignment than Comparative Composition 5. The hair that received Example Composition F also exhibited lightweight moisture. The section of hair that received Comparative Composition 5 had more frizz, felt greasy, and took longer to dry.
Example Composition D was evaluated in comparison to a Comparative Composition 6 (Comp. 6), which is a commercially available product. The list of ingredients for Comparative Composition 6 is provided below:
The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition D was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 6 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition D had good slip and was more topical than Comparative Composition 6. Additionally, the section that received Example Composition D was easier to detangle than the section of hair that received Comparative Composition 6. Comparative Composition 6 absorbed quickly into the hair, had a clean feel, and retained a wet feel for long time.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition D had more volume, a powdery feel, and good slip. The section of hair that received Comparative Composition 6 had dry ends, less aligned fibers, and a heavier feel than Example Composition D.
Example Composition D was evaluated in comparison to a Comparative Composition 7 (Comp. 7), which is a commercially available product. The list of ingredients for Comparative Composition 7 is provided below:
The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition D was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 7 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition D absorbed into the hair quickly and detangled the hair. The section of hair that received Comparative Composition 7 had good slip and detangled the hair. Comparative Composition 7 had more on-surface feel than Example Composition D. In other words Comparative Composition 7 did not appear to penetrate the hair as fast as Example Composition D.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition D felt drier, had elongated curls, and was shiner than Comparative Composition 7. Comparative Composition 7 had good slip and slight curl definition, but left a residue feel. Comparative Composition 7 had better curl pick up than Example Composition D. Example composition D provided more of a natural feel on the hair than Comparative Composition 7. Composition D also provided shine and elongation benefits compared to Comparative Composition 7.
Example Composition D was evaluated in comparison to a Comparative Composition 8 (Comp. 8), which is a commercially available product. The list of ingredients for Comparative Composition 8 is provided below:
The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition D was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 8 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition D took slightly longer to detangle the hair than Comparative Composition 8. Comparative Composition 8 was easy to apply and absorbed into the hair with smoothness.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition D had better fiber alignment, better curl definition, and drier ends than the hair that received Comparative Composition 8. The hair that received Comparative Composition 8 was smooth and soft. However, the hair that received Comparative Composition 8 had less curl definition than the section of hair that received Example composition D.
Example Composition A was evaluated in comparison to a Comparative Composition 9 (Comp. 9), which is a commercially available product. The list of ingredients for Comparative Composition 9 is provided below:
The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition A was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 9 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition A was easily absorbed into the hair and helped detangle hair. While Comparative Composition 9 was lightweight, Comparative Composition 9 did not absorb into the hair.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition A had better curl definition and better fiber alignment than Comparative Composition 9. The hair that received Example Composition A also had sealed ends, felt conditioned, and had shiny soft ringlets with beneficial root lift. The hair that received Comparative Composition 9, however, was very frizzy, had no curl definition, and felt dry.
Example Composition A was evaluated in comparison to a Comparative Composition 10 (Comp. 10), which is a commercially available product. The list of ingredients for Comparative Composition 10 is provided below:
The manikin's hair was washed before application of the samples. More specifically, the sample of Example Composition A was uniformly applied to a first half of the manikin's hair and the sample of Comparative Composition 10 was uniformly applied to the second half of the manikin's hair.
During application of the compositions, it was determined that Example Composition A was easily absorbed into the hair and helped detangle hair. Comparative Composition 10 did not easily change or effect the hair. For instance, Comparative Composition 10 did not provide distribution or detangling benefits.
The manikin's hair was allowed to dry and was then evaluated again. The section of hair that received Example Composition A had elongated curls that were soft and conditioned. The hair that received Example Composition A had good slip all the way to the ends. The hair that received Comparative Composition 10 was shiny, had good fiber alignment, and felt conditioned. The hair that received Comparative Composition 10, however, felt heavy as compared to the hair that received Example Composition A.
It is believed that certain exemplary compositions presented in Example 1 produce emulsions with an aqueous phase and an oil phase having the following ingredients as specified in the following table.
