Description

[Technical field]

[0001] The present invention relates to a solid cosmetic composition, a method for producing said solid cosmetic composition, a product prepared by said method, and a cosmetic method using said solid cosmetic composition. [Background technology]

[0002] The present invention relates to a solid cosmetic composition, in particular a solid cosmetic composition for use on hair. The present invention is primarily intended for use on hair, but may also be used on skin or other materials.

[0003] Nowadays, many cosmetic products are typically provided to consumers in the form of liquids or pastes. For example, hair treatments and products, especially cosmetic products used for dyeing, are traditionally provided in rigid or semi-rigid plastic containers or foil containers in the form of sachets. Containers add significantly to product costs. From an environmental protection perspective, packaging waste is a major problem, even if there are possibilities for recycling.

[0004] Henna has traditionally been sold in powder and paste form that typically requires packaging for its transportation and storage, and is sold as a coloring agent in hair rinses, skin dyes, fabric dyes, etc. As previously mentioned, the need for packaging is a drawback.

[0005] GB 2 369 995 A describes a bar product containing henna and cocoa butter, with the amount of cocoa butter listed as a preferred amount being 30% by weight. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] GB Patent Application Publication No. 2369995 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention seeks to provide a solid cosmetic product that provides users with an improved hair dye product and improved delivery of henna while avoiding the need for external packaging. [Means for solving the problem]

[0008] According to a first aspect of the present invention, there is provided a solid cosmetic composition comprising: (i) henna in an amount of about 5% to about 75% by weight of the solid cosmetic composition; (ii) hard vegetable butter in an amount of about 5% to about 35% by weight of the solid cosmetic composition; and (iii) polyol in an amount of about 1% to about 35% by weight of the solid cosmetic composition.

[0009] According to a further aspect of the present invention, there is provided a method for producing a solid cosmetic composition according to the first aspect of the present invention, comprising the steps of: (a) (i) henna; (ii) vegetable hard butter; (iii) a polyol; and (b) solidifying the resulting combination A method is provided that includes:

[0010] According to a further aspect of the present invention, (a) (i) henna; (ii) vegetable hard butter; (iii) a polyol; and (b) solidifying the resulting combination There is provided a solid cosmetic composition obtained or obtainable by a process comprising the steps of:

[0011] According to a further aspect of the present invention, there is provided a solid cosmetic composition comprising: (i) henna; (ii) a vegetable hard butter; and (iii) a herbal dye material selected from the group consisting of hibiscus, noni fruit, and combinations thereof.

[0012] According to a further aspect of the present invention, there is provided a cosmetic method comprising the step of contacting a user's hair with the solid cosmetic composition described herein.

[0013] The composition of the present invention comprising henna may be used as a hair dye in solid form. GB 2369995 A1 states that the inclusion of cocoa butter is necessary to provide a hair dye product with acceptable solidity and thus without the need for packaging. The amount of cocoa butter in conventional products is relatively high, typically in the range of about 30-40%. It has now surprisingly been found by the inventors that by using lower amounts of cocoa butter or other vegetable hard butters, a product can be obtained which, when applied to the hair, gives the hair deeper shades of colour and more uniform coverage. The product may also provide an improved colour when applied to the hair. In particular, it has been found that the dyeing materials contained in the product have the ability to deposit more pigment on the hair strand.

[0014] However, it has been found that reducing or eliminating the vegetable hard butter results in a composition that cannot maintain its physical shape without the support of a package.It has also been found that the vegetable hard butter provides hair with conditioning and moisturizing benefits.The inventors have surprisingly found that by using a combination of vegetable hard butter and polyol, such as glycerol, a composition is obtained that has acceptable solidity and hardness, and therefore can be easily handled and transported without the need for external packaging, and furthermore, a hair dye product is obtained that provides a deeper color and more uniform coverage on the hair than previously possible.The resulting product has also been found to still provide the desired conditioning and moisturizing benefits on the hair.

[0015] It was found that without the presence of polyol, the reduced cocoa butter products were drier and more prone to crumbling, and more effort was required to press them into the shape of a moulded brick. It was therefore surprising to find that the inclusion of polyol improved the solidity of the product, reduced the impact of crumbling or cracking, and further improved the coverage of the product on the hair. It was found that the resulting product may provide improved coverage, especially on grey hair.

[0016] Moreover, it has been surprisingly found that the combination of vegetable hard butter with polyol (e.g. glycerol) results in a solid product that is easier to apply to hair. It has been found that the product is easier to break into small pieces, and then melted to make the product ready for application to hair. It has also been found that the product can be melted more quickly.

[0017] It has also been found that, by virtue of its solid form, the composition can be resistant to microbial growth without the need for the use of synthetic preservatives, and therefore the composition can be treated as "preservative-free."

[0018] Furthermore, it has surprisingly been found by the inventors that when vegetable hard butters and henna are combined with hibiscus and / or noni fruit, enhanced hair colouring benefits can be achieved in that deeper and richer tones are achieved as compared to compositions not containing such herbal materials.

[0019] These and further aspects of the present invention are discussed below under appropriate section headings for ease of reference, although the teachings in each section are not necessarily limited to each particular section. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] composition As described herein, in one aspect of the present invention, there is provided a solid cosmetic composition comprising: (i) henna in an amount of about 5% to about 75% by weight of the solid cosmetic composition; (ii) vegetable hard butter in an amount of about 5% to about 35% by weight of the solid cosmetic composition; and (iii) polyol in an amount of about 1% to about 35% by weight of the solid cosmetic composition.

[0021] As will be appreciated by those skilled in the art, the nature of a cosmetic product means that the product is not edible. Accordingly, the present invention provides a non-edible solid cosmetic composition as defined herein.

[0022] The solid cosmetic product of the present invention is a composition that can substantially retain its physical shape even when not supported by external means, such as a package. Thus, the solid cosmetic product of the present invention is recognized to be in a solid, solid-like, solid form or solid-like form at room temperature. For the avoidance of doubt, a solid product is a product that remains substantially solid up to a temperature of 30° C.

[0023] By solid-like it is understood that some materials, for example amorphous materials such as glass, may be considered solid on a day to day basis but may change shape over a very long period of time, however such materials are considered solid-like because they are solid for the purposes they serve.

[0024] As mentioned above, the composition of the present invention is in a solid form, so that no external packaging is required to maintain the shape of the composition.The solid form of the composition of the present invention therefore allows for beneficial cost reduction and environmental pollution reduction, which is achieved by avoiding the necessity of packaging or containers.In addition, being in a solid form, the composition can accept markings or stamps that may be applied during manufacturing.

[0025] Henna and coloring materials As described herein, the solid cosmetic composition comprises henna. Henna is a dye prepared from the plant Lawsonia intermis, sometimes referred to as the "henna tree." As used herein, the term "henna" refers only to materials derived from the henna tree and does not refer to other skin and hair dyes, such as black henna and neutral henna, neither of which are derived from the henna tree. Henna is a colorant and may be used to color a user's skin or hair, and may also impart shine to a user's hair.

[0026] Henna may be included in the composition in powdered form. Henna may be provided in milled form from leaves from the henna plant. Henna may preferably be red henna.

[0029] In some embodiments, the solid cosmetic composition may include other pigments, dyes, or coloring materials in addition to henna. Such additional pigments, dyes, or coloring materials may be included to enhance the color provided by the henna, or to adjust the overall color provided by the composition to the hair, or a combination of the two. For example, additional coloring materials may be included to lighten or darken the shade provided by the henna, or may simply be included to increase the intensity of the color provided by the henna. Preferably, any additional dyes, dyes, or coloring materials may be derived from natural sources.

[0030] In some embodiments, the solid cosmetic composition can include a herbal dyeing material. The herbal dyeing material is other than henna. This means that the herbal dyeing material is a dyeing material derived from a natural source other than the henna plant (Lawsonia intermis). The herbal dyeing material can be a material that contains a pigment capable of coloring the hair or skin of a user, and therefore may also be referred to as a coloring material.

[0031] The herbal dyeing material may be any suitable naturally occurring material capable of coloring the hair or skin of a user. The herbal dyeing material may be selected from natural pigments such as beet root, chlorophyll, gardenia, blackberry, coffee, rose, caramel powder, grape, alfalfa, walnut shell, calendula, cocoa, green tea, hibiscus, kelp, olive, orange, parsley, pumpkin, spinach, spirulina, wheatgrass source, sandalwood, saffron, safflower, turmeric, butterfly pea, carrot, tomato, indigo, Irish moss, nettle, noni fruit, rhubarb root, rosemary, chamomile, cassia obtava (also commonly known as "neutral henna"), spikenard, and mixtures thereof.

[0032] Herbal dye materials include beet root, chlorophyll, gardenia, blackberry, coffee, rose, caramel powder, grapes, alfalfa, walnut shells, calendula, cocoa, green tea, hibiscus, kelp, olives, oranges, parsley, pumpkin, spinach, spirulina, wheatgrass source, sandalwood, saffron, safflower, turmeric, butterfly pea, carrot, tomato, indigo, Irish moss, nettle, noni fruit, rhubarb root, rosemary, chamomile, cassia obtusifolia (also known as "neutral henna"), spikenard, amla (Indian gooseberry), Bhrinhraj / Maca (Eclipta alba or Eclipta prostrata), Kuth root, valerian root, alkanet, blueberries, pomegranates and combinations thereof.

[0033] Preferably, the herbal dyeing material may be selected from the group consisting of indigo, Irish moss, nettle, coffee (e.g., coffee grounds), noni fruit, hibiscus, rhubarb root, rosemary, chamomile, cassia obtusifolia, spikenard, amla (phyllaceae), bhrinharaj / maca (American common sage or common sage), camphor root, valerian root, alkanet, blueberry, pomegranate, and mixtures thereof. Preferably, the herbal dyeing material may be selected from the group consisting of indigo, Irish moss, nettle, coffee (e.g., coffee grounds), noni fruit, hibiscus, rhubarb root, rosemary, chamomile, cassia obtusifolia, spikenard, and mixtures thereof. The herbal dyeing material may be added preferably in powder form.

[0034] In some embodiments, the herbaceous dye material may be present in an amount of about 5% to about 60% by weight of the solid cosmetic composition, for example, about 5% to about 55% by weight of the solid cosmetic composition, for example, about 5% to about 50% by weight of the solid cosmetic composition. In some embodiments, the herbaceous dye material may be present in an amount of about 10% to about 50% by weight of the solid cosmetic composition, for example, about 20% to about 45% by weight of the solid cosmetic composition, for example, about 25% to about 40% by weight of the solid cosmetic composition.

[0035] In some preferred embodiments, the total amount of henna and plant dyeing materials combined is about 40% to about 94% by weight of the solid cosmetic composition. The "total amount combined" refers to the sum of the amount of henna and the amount of plant dyeing materials other than henna. The total amount of henna and plant dyeing materials combined is preferably about 45% to about 90% by weight of the solid cosmetic composition, for example, about 50% to about 80% by weight of the solid cosmetic composition, for example, about 55% to about 75% by weight of the solid cosmetic composition, for example, about 60% to about 70% by weight of the solid cosmetic composition, for example, about 65% to about 70% by weight of the solid cosmetic composition. In some preferred embodiments, the total amount of henna and plant dyeing materials combined is about 40% to about 80% by weight of the solid cosmetic composition.

[0036] In some embodiments, the weight ratio of henna to herbal dye materials can be from about 15:1 to about 1:5, such as from about 10:1 to about 1:3, such as from about 5:1 to about 1:3. Depending on the desired hair shade, the weight ratio of henna to herbal dye materials can be from about 2:1 to about 1:3, such as from about 1.5:1 to about 2:1.

[0037] In some preferred embodiments, the solid cosmetic composition comprises a herbal dyeing material, the herbal dyeing material comprising at least indigo. The indigo herb may be derived from the plant Indigofera tinctoria and is a blue dye. It has been found that the indigo herb can impart an inky black color to hair. The inventors have found that when combined with henna, indigo can provide a warm colour tone and an even coverage of colour to hair. True indigo is a shrub of the legume family that is grown in tropical and subtropical climates. Indigo powder can be obtained by drying and then grinding the leaves of this plant. When present, indigo (preferably in powder form) may be included in an amount of about 5% to about 50% by weight of the solid cosmetic composition, for example, about 5% to about 20% by weight, or about 25% to about 45% by weight of the solid cosmetic composition.

[0038] Preferably, the solid cosmetic composition comprises a herbal dyeing material, the herbal dyeing material comprising at least indigo, noni fruit, hibiscus, spikenard or a combination thereof. Preferably, the solid cosmetic composition comprises a herbal dyeing material, the herbal dyeing material comprising at least indigo powder, noni fruit powder, hibiscus powder, spikenard or a combination thereof.

[0039] Preferably, the solid cosmetic composition comprises a herbal dyeing material, and the herbal dyeing material comprises at least noni fruit, hibiscus, or a combination thereof. Preferably, the solid cosmetic composition comprises a herbal dyeing material, and the herbal dyeing material comprises at least noni fruit powder, hibiscus powder, or a combination thereof. Surprisingly, the present inventors have found that the inclusion of at least one of noni fruit and hibiscus (preferably in powder form) can improve the color imparted to skin or hair by the solid cosmetic composition. For example, it has been found that henna can sometimes have an orange tone when applied to hair, but noni fruit and / or hibiscus can reduce the orange tone, which tends to be strong. In particular, it has been found that the inclusion of at least noni fruit and / or hibiscus in combination with henna results in a product with improved color tone compared to a product that does not include such herbal dyeing material. The resulting hair color can be deeper and have a cooler tone.

[0040] In some embodiments, the solid cosmetic composition may contain at least one of noni fruit and hibiscus in an amount of 0.1% by weight to about 15% by weight of the solid cosmetic composition, for example, about 0.5% by weight to about 10% by weight of the solid cosmetic composition, for example, about 1% by weight to about 9% by weight of the solid cosmetic composition, for example, about 2% by weight to about 8% by weight of the solid cosmetic composition. These amounts refer to the total amount of noni fruit and / or hibiscus combined, and may be the total amount in powder form.

[0041] In some embodiments, the herbal dyeing material includes at least hibiscus powder. In some embodiments, the herbal dyeing material is hibiscus powder. The herbal dyeing material may be or include hibiscus powder in an amount of about 0.1% to about 15% by weight of the solid cosmetic composition, for example, about 0.5% to about 12.5% ​​by weight of the solid cosmetic composition, for example, about 1% to about 10% by weight of the solid cosmetic composition, for example, about 5% to about 10% by weight of the solid cosmetic composition.

[0042] Hibiscus is a genus of flowering plants in the Malvaceae family. Hibiscus powder can be obtained from the leaves and / or flowers of the hibiscus plant. Preferably, the hibiscus powder is obtained from the flowers of the hibiscus plant. Hibiscus powder can provide a gentle cleansing and conditioning effect as well as a coloring effect for the skin or hair of the user. Hibiscus powder can also increase the shine of hair and improve the color tone of hair when combined with henna.

[0043] In some embodiments, the herbal dyeing material includes at least noni fruit powder. In some embodiments, the herbal dyeing material is noni fruit powder. The herbal dyeing material may be or include noni fruit powder in an amount of about 0.1% by weight to about 15% by weight of the solid cosmetic composition, for example, about 0.5% by weight to about 10% by weight of the solid cosmetic composition, for example, about 1% by weight to about 5% by weight of the solid cosmetic composition, for example, about 2% by weight to about 5% by weight of the solid cosmetic composition.

[0044] Noni is an evergreen tree called Morinda citrifolia, with large leaves and yellow fruits. Noni fruit powder can be derived from the dried ripe or unripe fruits of the Noni tree, and is rich in vitamins, minerals and antioxidants. Noni fruit powder can enhance the shine in hair and can also improve hair color when combined with henna.

[0045] Vegetable hard butter As described herein, the solid cosmetic composition comprises a vegetable hard butter. The term "vegetable butter" as used herein refers to a triglyceride derived from a plant or vegetable source and recognized as solid (including the solid-like discussed above) at normal use temperature. Thus, vegetable butter is a triglyceride that is substantially solid at room temperature. Vegetable butter typically has the consistency of butter. However, it is understood that the solid fat content of vegetable butter at normal use temperature does not have to be 100%. In a preferred embodiment, the solid fat content of the solid fat is at least 70%, preferably at least 80%, preferably at least 90%, preferably at least 95%, preferably at least 98%, preferably at least 99% at 25°C.

[0046] The term vegetable "hard" butter refers to vegetable butter containing a majority of saturated fatty acids. In particular, vegetable hard butter typically contains more than 60% by weight of saturated fatty acids based on the total fatty acids of the highly saturated vegetable butter. Therefore, vegetable hard butter can also be referred to as highly saturated vegetable butter.

[0047] In some embodiments, the vegetable hard butter may be selected from the group consisting of cocoa butter, illipe butter, murumuru butter, kokum butter, coconut oil, palm kernel oil, and mixtures thereof. Although coconut oil and palm kernel oil may typically be referred to as "oils," they can be considered vegetable hard butters because they are solid at room temperature and have a high saturated fat content.

[0048] In some embodiments, the vegetable hard butter may be selected from the group consisting of cocoa butter, illipe butter, murumuru butter, kokum butter, coconut oil, and mixtures thereof.

[0049] In some preferred embodiments, the vegetable hard butter comprises at least cocoa butter. In some preferred embodiments, the vegetable hard butter is cocoa butter.

[0050] In some embodiments, the vegetable hard butter (eg, cocoa butter) may be present in an amount of about 5% to about 35% by weight of the solid cosmetic composition.

[0051] In some embodiments, the vegetable hard butter (e.g., cocoa butter) may be present in an amount of about 5% by weight to about 30% by weight of the solid cosmetic composition, for example, about 5% by weight to about 25% by weight of the solid cosmetic composition, for example, about 5% by weight to about 20% by weight of the solid cosmetic composition, for example, about 10% by weight to about 20% by weight of the solid cosmetic composition, for example, about 10% by weight to about 15% by weight of the solid cosmetic composition.

[0052] The vegetable hard butter (e.g., cocoa butter) may be preferably present in an amount of at least 5% of the composition to provide the solid cosmetic composition with sufficient solidity to be stored for a long period of time without the need for packaging. However, it has been surprisingly found that if too much cocoa butter is included, the composition may increase the unevenness of color coverage on the hair when applied to the hair, and may even weaken the color development. It has been surprisingly found that if the vegetable hard butter is included in the composition in an amount lower than that conventionally used, the resulting hair color is a brighter shade, with increased depth and coverage. Thus, the amount of vegetable hard butter in the solid cosmetic composition is about 35% by weight or less, for example about 30% by weight or less, of the solid cosmetic composition. In some preferred embodiments, the amount of vegetable hard butter in the solid cosmetic composition may be about 25% by weight or less, preferably about 20% by weight or less, or about 15% by weight or less of the solid cosmetic composition.

[0053] In some embodiments, the solid cosmetic composition comprises a vegetable hard butter (e.g., cocoa butter) in an amount of about 11% to about 19% by weight of the solid cosmetic composition, for example, about 12% to about 18% by weight, for example, about 13% to about 17% by weight, for example, about 14% to about 16% by weight, for example, approximately 15% by weight.

[0054] Polyol As described herein, the solid cosmetic composition comprises a polyol. The term "polyol" refers to an organic compound that contains two or more hydroxyl groups.

[0055] In some embodiments, the polyol may be or may include a sugar alcohol. The term "sugar alcohol" refers to a class of low molecular weight polyols that can typically be derived from sugars, for example, by hydrogenation. Sugar alcohols can contain one hydroxyl group attached directly or indirectly to each carbon atom in the chain. Examples of sugar alcohols include ethylene glycol, glycerol, erythritol, threitol, arabitol, xylitol, ribitol, mannitol, sorbitol, galactitol, inositol, isomalt, maltitol, and lactitol.

[0056] Alternatively or additionally, the polyol may be or include propylene glycol (propane-1,2-diol) or propane-1,3-diol.

[0057] In some embodiments, the polyol may be selected from the group consisting of ethylene glycol, glycerol, erythritol, threitol, arabitol, xylitol, ribitol, mannitol, sorbitol, galactitol, inositol, isomalt, maltitol, lactitol, propylene glycol, propane-1,3-diol, and mixtures thereof. In some embodiments, the polyol may be selected from the group consisting of glycerol, propylene glycol, propane-1,3-diol, sorbitol, xylitol, isomalt, erythritol, lactitol, mannitol, maltitol, and mixtures thereof. In some embodiments, the polyol may be selected from the group consisting of glycerol, sorbitol, xylitol, isomalt, mannitol, and mixtures thereof. In some embodiments, the polyol may be selected from the group consisting of glycerol, sorbitol, and mixtures thereof.

[0058] In some preferred embodiments, the solid cosmetic composition may be free or substantially free of propylene glycol (i.e., less than 1% by weight, if any). Thus, in some embodiments, the polyol may not be propylene glycol or may not contain propylene glycol.

[0059] In some preferred embodiments, the polyol comprises at least glycerol. Preferably, the polyol is glycerol.

[0060] In some embodiments, the solid cosmetic composition comprises a polyol (e.g., glycerol) in an amount of from about 0.1% to about 50% by weight of the solid cosmetic composition, for example, from about 0.5% to about 40% by weight of the solid cosmetic composition.

[0061] In a preferred embodiment, the solid cosmetic composition contains a polyol (e.g., glycerol) in an amount of about 1% by weight to about 35% by weight of the solid cosmetic composition. In some embodiments, the solid cosmetic composition contains a polyol (e.g., glycerol) in an amount of about 5% by weight to about 30% by weight of the solid cosmetic composition, for example, about 10% by weight to about 25% by weight of the solid cosmetic composition, for example, about 10% by weight to about 20% by weight of the solid cosmetic composition. In some embodiments, the solid cosmetic composition may contain a polyol (e.g., glycerol) in an amount of about 5% by weight to about 20% by weight of the solid cosmetic composition.

[0062] Further ingredients In addition to the above, the cosmetic composition may further comprise one or more cosmetically acceptable additives. Those skilled in the art will recognize the range of cosmetically acceptable additives suitable for incorporation into such compositions.

Suitable emulsifying waxes include cetearyl alcohol (also known as cetostearyl alcohol or cetylstearyl alcohol), stearic acid, glyceryl stearate, a combination of cetearyl alcohol and sodium lauryl sulphate (SLS), and mixtures thereof.

[0079] The solid cosmetic composition may further include a vegetable soft butter, a vegetable oil, and / or a wax in addition to the vegetable hard butter. However, it is preferable that the composition does not include a significant amount of additional butter, oil, or wax to the vegetable hard butter, and preferably, no such additional butter, oil, or wax is used. Preferably, the total amount of the vegetable soft butter, vegetable oil, and wax combined is 10% by weight or less, preferably 5% by weight or less, more preferably 1% by weight or less of the solid cosmetic composition. In some embodiments, the solid cosmetic composition does not include any of the vegetable soft butter, vegetable oil, and wax. "Vegetable soft butter" means a vegetable low saturated butter containing less than 60% by weight of saturated fatty acids based on the total fatty acids of the vegetable low saturated butter. "Vegetable oil" refers to a vegetable triglyceride that is liquid at room temperature.

[0080] In some embodiments, the vegetable hard butter is the only source of fat or triglycerides present in the composition.

[0081] Overall composition In some embodiments, the weight ratio of the vegetable hard butter (e.g., cocoa butter) to the polyol (e.g., glycerol) is about 10:1 to about 1:10, such as about 5:1 to about 1:5, such as about 4:1 to about 1:4, such as about 2:1 to about 1:2, such as about 1:1. In some preferred embodiments, the weight ratio of the vegetable hard butter (e.g., cocoa butter) to the polyol (e.g., glycerol) can be about 1:2 to about 1:1. The inventors have found that when the vegetable hard butter and the polyol are used in such a weight ratio, the composition has an acceptable solidity and hardness that allows for easy handling and transportation, and has a good feel in the hands of the user, while still providing improved and desirable color intensity to the hair and / or skin. For example, if the weight ratio of the vegetable hard butter to the polyol agent is too low, the product may not be able to be sufficiently solidified, and may even become sticky or tacky over time (e.g., during storage). If the weight ratio of vegetable hard butter to polyol is too high, the product may not provide sufficient color intensity or uniform coverage on the user's hair, which may result in a less than desirable finish.

[0082] In some embodiments, the weight ratio of henna to vegetable hard butter (e.g., cocoa butter) is from about 1:1 to about 10:1, such as from about 1:1 to about 1:5. Surprisingly, it has been found that by reducing the relative amount of vegetable hard butter in the formulation, enhanced color development can be achieved when the product is applied to hair. For example, improved coverage of color on hair can be achieved, and color intensity on hair can be increased.

[0083] In some embodiments, the solid cosmetic composition comprises: (i) henna in an amount of about 5% by weight to about 75% by weight of the solid cosmetic composition; (ii) cocoa butter in an amount of about 5% to about 35% by weight of the solid cosmetic composition; (iii) glycerol in an amount of about 1% by weight to about 35% by weight of the solid cosmetic composition; Includes.

[0088] Process As described herein, there is provided a method for producing a solid cosmetic composition as defined herein, comprising the steps of: (a) (i) henna; (ii) vegetable hard butter; (iii) a polyol; and (b) solidifying the resulting combination A method is provided that includes:

[0089] As described herein, the solid cosmetic composition may further comprise one or more cosmetically acceptable additives. In some embodiments, the method further comprises combining one or more cosmetically acceptable additives as defined herein with the mixture of step (a). For example, in some embodiments, the method further comprises adding fruit juice, herbal dyeing materials, or combinations thereof before, during, or after performing step (a). The herbal dyeing materials may be added in powder form.

[0090] For example, additives, if any, may be added to the container together with the henna, vegetable butter, and polyol all at about the same time (i.e., during the performance of step (a)). Alternatively, additives, if any, may be added after the henna, vegetable butter, and polyol have already been combined (i.e., after the performance of step (a)) and prior to the step of solidifying the resulting combination.

[0091] In some particular embodiments where the composition includes a herbal dyeing material, the henna and herbal dyeing material may be combined (e.g., by mixing). If the herbal dyeing material and the henna are provided as powders, the powders may be added together (e.g., by sieving). Alternatively, the vegetable hard butter and the polyol may be combined (e.g., by mixing). The herbal dyeing material and henna combination may then be slowly added to the vegetable hard butter and polyol combination while mixing.

[0092] Step (b) may involve a passive solidification step, in which the mixture is simply left at room temperature and exposed to air under ambient pressure and humidity for a period of time until the mixture solidifies. For example, the mixture may be allowed to solidify by leaving it for at least about 1 hour, preferably at least 12 hours or 24 hours.

[0093] In some embodiments, step (b) may involve an active solidification step, which may include adjusting the ambient temperature, pressure or humidity to increase the rate of solidification.

[0094] Step (b) may include pouring the combination obtained in step (a) into a mould before solidifying it. In this way, a moulded product may be formed. Optionally, the mixture may be pressed when added to the mould or during the drying process to obtain a product in the form of a moulded bar or brick.

[0095] In some embodiments, the combination obtained from step (a) is in the form of a paste, which may then be hardened to provide a solid cosmetic composition.

[0096] The shape of the solid composition of the present invention is not limited. The solid composition can have a shape that is aesthetically pleasing and / or aids in the use of the product. For example, the solid product can be manufactured in such a manner that it solidifies in a shape that is ergonomically acceptable to the user. Thus, in some embodiments of the method of the present invention, the solid product is manufactured by pouring and / or pressing the mixture resulting from carrying out step (a) into a mold, allowing it to solidify, and then removing it.

[0097] The solid form of the composition may have some decoration or instructions on its surface, which may be applied before, during or after step (b) of the above method. For example, the product may be stamped with a design (e.g., letters or pictures) before, during or after solidification. For example, the product may be stamped while it is solidifying but before the product is completely set. In some embodiments, the composition may be etched or have some image or wording on its surface.

[0149] Method As described herein, there is provided a cosmetic method comprising the step of contacting the hair of a user with a solid cosmetic composition as defined herein.

[0150] The present invention is primarily intended for use on hair (particularly as a dye for coloring hair), but may also be used on skin or other materials. Thus, in one aspect, there is also provided a cosmetic method comprising contacting the hair or skin of a user with a solid cosmetic composition as defined herein.

[0151] As will be appreciated by those skilled in the art, given the solid nature of the present invention, a user may directly contact the solid cosmetic composition with the skin or hair, without the need to dispense the product from within any external packaging prior to application to the skin, as is the case with conventional liquid hair dyes or colorants.

[0152] Preferably, the solid cosmetic composition comprises: (i) contacting a solid cosmetic composition with water; (ii) melting the solid cosmetic composition by heating the water to obtain a semi-solid (e.g., gel-like) or viscous liquid; (iii) applying a semi-solid or liquid substance to the user's hair. The hair of the user can be contacted by a method comprising:

[0153] For example, to use the product of the present invention, the end user typically places the product in a container. A small amount of lukewarm or hot water can then be added to the container, typically just covering the solid product. This causes the product to begin to disperse. Once a significant amount of the product is dispersed, more water can be added and the product can be gently stirred. Water can then be added until the dispersed product produces a desired consistency. This consistency can be determined by the user, for example, based on their own preferences or their own hair type or condition.

[0154] Before applying water to the product, the product may be broken into small pieces. For example, the composition may be in the form of a bar or brick, from which the portion to be applied to hair is broken or broken off. Surprisingly, it has been found that the use of a combination of vegetable hard butter and polyol (e.g., glycerol) results in a solid product that is easier to break into small pieces and can then be melted to make the product ready for application to hair, compared to products containing high levels of cocoa butter. It has also been found that the product can be melted more quickly when added to heated water.

[0155] Once applied to the hair, the product may be left on the hair for at least 30 minutes, preferably at least 1 hour, preferably not more than 2 hours, after which the hair may be rinsed.

[0165] A bar product was prepared according to claim 1. The product contained the following ingredients: - Red Henna Powder - Glycerol - Cocoa butter - Indigo powder - Hibiscus flower powder - Coffee grinds - Lemon juice -Fragrance - Irish moss powder

[0166] The product of claim 1 was compared to a commercial product, Marron Henna Brick, sold by Lush Limited, which contains the same ingredients as those previously mentioned, except that it does not contain glycerol or hibiscus powder.

[0167] A panel of 20 independent subjects was provided with each sample of the product according to claim 1 for testing purposes. Eight of these subjects had the product applied to them (using the method outlined below) and therefore did not prepare or apply the product themselves. The remaining 12 subjects were each asked to apply the product to their own hair using the method below. 1. Crush the bricks and gradually add freshly boiled water, stirring. 2. Apply Ultrabrand or Ultraplant to the hairline and around the ears. 3. Comb your hair into sections, make sure the Henna product is at a comfortable temperature, and apply it to the roots of your hair, starting from the nape and working your way up to the top of your head, using a brush if extra detail is required. 4. Apply a generous amount with your (gloved) hands to the entire length of your hair and to the ends, then gather the hair together at the top of your head. 5. Cover with a shower cap for a warming effect and leave on for up to 2 hours. 6. Rinse thoroughly.

[0168] Each subject was then asked to provide feedback on this product in comparison to the Marron Henna Brick.

[0169] The subjects were asked the following questions: Was this henna brick easier to prepare than traditional henna? - The eight subjects who had henna applied were not asked this question. - 12 out of 12 subjects answered "yes." The response comments included the following: "This henna brick was softer, easier to crumble / cut, and dissolved faster." "It took less time to dissolve than usual, was much easier to cut, and did not get a skin over it either." Was this henna brick easier to apply than traditional henna? - Of the 20 subjects, 4 who had someone else apply the product did not respond. - Of the remaining 16 subjects, 8 answered "yes" (3 answered "no change"). The response comments included the following: "It had a much smoother consistency and no solid chunks upon application." Is the resulting shade an improvement over previous times you have dyed your hair with henna? - 14 out of 20 subjects answered "yes" (3 subjects answered "no change"). EXAMPLES

[0170] A bar product was prepared according to claim 1. The product contained the following ingredients: - Indigo powder - Red Henna Powder - Glycerol - Cocoa butter - Noni fruit powder - Noni juice - Sea salt -Fragrance - Irish moss powder

[0171] The product of claim 1 was compared to comparative product 1 and comparative product 2. Comparative product 1 was the same as the claimed product but with glycerol replaced with a higher amount of cocoa butter. Comparative product 2 was the same as the claimed product but with glycerol replaced with almond oil. Neither comparative product contained glycerol or other polyols.

[0172] Each product was formulated and applied to blonde human hair using the method set forth in Example 5 above.

[0173] Comparative product 1, which contained only cocoa butter, was in solid form but was found to have "blooming" which resulted in the product surface becoming oxidized and patchy / spotty. This created an undesirable appearance which was deemed unpleasant to the user. In contrast, the product according to claim 1 had a smooth finish and the product was in solid form with no cracks or crumbling.

[0174] The product as claimed in claim 1 has been found to provide the most desirable product in that it is a solid brick which when applied to the hair results in the deepest and coolest shade.

[0175] When applied to hair, Comparative Product 1 dyed the hair in a manner that resulted in a warmer (less desirable) appearance compared to the appearance achieved with the claimed product containing cocoa butter and glycerol.

[0176] When Comparative Product 2 containing almond oil was applied to hair, it stained the hair with uneven coverage and a patchy finish. Darker spots formed on the hair. EXAMPLES

[0177] Bar products were prepared according to claim 26 and consumer tested, all containing henna, cocoa butter, and at least one of noni fruit and hibiscus powder.

[0178] The bars were tested by a panel of subjects using the methods set forth in Example 5 above.

[0179] Some of the subjects were users of conventional commercial henna products. These subjects were asked to compare the product of claim 26 with their conventional commercial henna products. Most of the subjects who used conventional commercial henna products stated that the new product was equal to or better than the conventional products in some respects. Some felt that the new product was easier to apply, and some felt that the color was improved compared to the conventional products.

[0180] Various modifications and variations of this invention will become apparent to those skilled in the art without departing from the scope and spirit of the invention.
