Description

[Technical field]

[0001] The present invention relates to a solid cosmetic product, a process for making said product, and the product prepared by said process. [Background technology]

[0002] The present invention relates to articles of manufacture, particularly articles intended for use in contact with the human body.

[0003] Cosmetics, in its broadest definition, is a range of products used to enhance or maintain the appearance or fragrance of the human body. They include cosmetics, moisturizers, fragrances, such as perfumes, bath products, dental products, oral hygiene products, such as toothpaste, cleansing products, such as soaps, and hair products, such as shampoos and conditioners. Many of these products have traditionally been supplied in the form of liquids or pastes, which have necessarily required storage in containers. Traditionally, these containers may have been reusable, but since the introduction of bulk packaging, the containers have typically been disposable containers, often made of plastic materials. Whether or not the containers are recycled, the use of unnecessary packaging is inherently detrimental to the environment, at least due to the energy required to manufacture and transport the packaging. Furthermore, the supply of such cosmetic products in liquid form encourages manufacturers to include unnecessary amounts of water in the products. This leads to the use of additional energy for the transportation of the additional water. Summary of the Invention [Means for solving the problem]

[0009] For ease of reference, these and further aspects of the present invention are discussed herein under appropriate section headings, however, the teachings under each section are not necessarily limited to each particular section. Effect of the Invention

[0010] The inventors have found that by achieving a particular balance of vegetable butters, waxes, and emulsifying materials, a solid cosmetic product can be formed that not only addresses the environmental concerns of non-solid products, but also provides a more attractive product for the end user. In particular, the present invention can allow for the formation of a product with desired properties, such as being handled without disintegrating the solid product. The composition can be formed into the desired solid cosmetic product by "conventional" means, such as by using a mold, or it can also be suitable for 3D printing. In both aspects, the present invention can allow for the formation of products with intricate or complex shapes and / or fine or detailed surface finishes. When utilizing 3D printing, for example, products made according to the present invention can contain angles, such as obtuse angles that are impossible to release from a mold, but also interlocking or cooperating parts, and other such intricate designs. The present invention can also allow for the preparation of products, for example, by operating a 3D printing method, where the product cools and solidifies at a speed and / or in a manner that allows for rapid production of the product and the production of a product that is aesthetically acceptable to the end consumer.

[0011] In one embodiment illustrating the advantages of the present invention, the composition was used to create a solid cosmetic product, namely, a mascara. The preparation of this product eliminates the need for packaging. The product itself may be considered to function as its own container. The specially formulated composition allows for molding or 3D printing while still providing a final mascara product that retains the required cosmetic properties. This is a major advantage over current mascaras, which are most commonly sold as liquids packaged with an applicator brush. Such products create a lot of plastic waste that cannot be widely recycled as a result of elaborate packaging (often exacerbated by packaging to hold small amounts of product). In contrast, solid mascaras are provided to mimic the appearance and function of mascara containers, and are adapted to be used with and hold any suitable existing eyelash brush. In use, the user only needs to slightly wet the brush and rub it along the inner surface of the mascara to release the pigment.

[0012] As can be understood, the present cosmetic composition can be used to prepare other cosmetic products. These additional products can also "form their own container", which can be configured based on the end use of the cosmetic product. For example, the product may not contain pigments. The present composition can be used to prepare products such as eyelash conditioners, face cosmetics such as foundations, body cosmetics, hair coloring, massage bars, and many other products.

[0014] As discussed herein, the present invention provides each of the following: (1) The following (a) one or more vegetable butters in a total amount of 20 to 80% by weight based on the cosmetic composition; (b) one or more waxes in a total amount of 3 to 45% by weight based on the cosmetic composition; (c) one or more emulsifying materials in a total amount of 5 to 40% by weight based on the cosmetic composition; 1. A cosmetic composition comprising: (2)(a) The following: (i) one or more vegetable butters in a total amount of 5 to 80% by weight based on the cosmetic composition; (ii) one or more waxes in a total amount of 3 to 45% by weight based on the cosmetic composition; (iii) one or more emulsifying materials in a total amount of 5 to 40% by weight based on the cosmetic composition; providing a solid cosmetic composition comprising: (b) heating the solid cosmetic composition to render the cosmetic composition flowable; (c) solidifying the flowable cosmetic composition to form a solid cosmetic composition; A product obtained or obtainable by a process comprising:

[0015] As will be appreciated by those skilled in the art, the nature of a cosmetic product means that the product is not edible. The term edible refers to a product that is suitable for eating as a food. Products that may be swallowed but are not suitable for use as a food, such as toothpaste or mouthwash, are not considered edible.

[0016] The solid products of the present invention are compositions that are capable of substantially maintaining their physical form even when not supported by external means, such as packaging. They are therefore considered to be solid, solid-like, solid-form or solid-like at room temperature. For the avoidance of doubt, the solid products must remain substantially solid up to 25°C.

[0017] By solid-like, it is understood that some materials may be considered solid on a day-to-day basis but may change shape over a very long period of time, such as amorphous materials, e.g., glass, but they are considered solid-like because they are solid for the purpose they fulfill.

[0018] Because the compositions of the present invention are in solid form, no external packaging is necessary to maintain the shape of the composition.

[0094] In one embodiment, the solid cosmetic composition is heated to a temperature not exceeding 15° C. above its melting point prior to step (c). In one embodiment, the solid cosmetic composition is heated to a temperature not exceeding 10° C. above its melting point prior to step (c). In one embodiment, the solid cosmetic composition is heated to a temperature not exceeding 5° C. above its melting point prior to step (c).

[0095] In one embodiment, the solid cosmetic composition is heated to a temperature not exceeding 15° C. above its melting point prior to 3D printing. In one embodiment, the solid cosmetic composition is heated to a temperature not exceeding 10° C. above its melting point prior to 3D printing. In one embodiment, the solid cosmetic composition is heated to a temperature not exceeding 5° C. above its melting point prior to 3D printing.

[0096] The present inventors have discovered that the printing process can be improved by "conditioning" the solid cosmetic composition before cooling, for example during printing. In particular, in one embodiment, the solid cosmetic composition is stored in a dehumidifier before printing. In one embodiment, the solid cosmetic composition is heated at a temperature of at least 32°C to make the cosmetic composition flowable.

[0097] 3D Printing As discussed herein, 3D printing, also known as additive manufacturing (AM), refers to a method used to synthesize a three-dimensional object in which successive layers of material are formed. The object can be in almost any shape or form and is manufactured using digital model data from a 3D model or another electronic data source. This printing process is extremely flexible and allows the formation of the above-mentioned products. By its nature, the requirement to provide successive layers of material means that at least two layers of the product must be deposited for the process to be properly defined as 3D printing. The present invention does not encompass a method of depositing a single layer of the product. In a preferred embodiment, the solid cosmetic composition comprises at least three layers of the cosmetic product deposited by 3D printing, such as at least four layers of the cosmetic product, such as at least five layers of the cosmetic product, such as at least seven layers of the cosmetic product, such as at least ten layers of the cosmetic product, such as at least fifteen layers of the cosmetic product.

[0098] In one embodiment, the solid cosmetic composition comprises at least one layer of a first cosmetic ingredient and at least one layer of a second cosmetic ingredient, where the first cosmetic ingredient and the second cosmetic ingredient are different cosmetic products. In this embodiment, a multi-functional cosmetic composition can be provided. For example, multiple cosmetic formulations or ingredients can be formed into a single product, which has various functional effects for the end user. Furthermore, multiple cosmetic formulations can be provided as a single product, where the cosmetic formulations may have some adverse interactions during storage. By providing a cosmetic formulation with separate layers rather than a mixture, an overall solid cosmetic composition can be provided that has the functionality of a mixture of the formulations, but the ingredients are stable during storage.

[0099] In one embodiment, the solid cosmetic composition comprises at least one layer of a first cosmetic ingredient and at least one layer of a second cosmetic ingredient, the first cosmetic ingredient and the second cosmetic ingredient being different in color. The first cosmetic ingredient and the second cosmetic ingredient being different in color may be the same cosmetic formulation or may be different cosmetic formulations. As will be understood, the same cosmetic formulation means a formulation having the same function, e.g., mascara, but different in color. If the first cosmetic ingredient and the second cosmetic ingredient are different formulations, the advantages described above with respect to layers of different formulations apply as well. Regardless of whether the formulations are the same or different, this aspect of the invention allows for the provision of a solid cosmetic composition having multiple colored layers that are attractive to the end user. By forming these multiple layers by 3D printing, it is possible to create a solid cosmetic composition in a more timely manner than a typical molding method. When a multi-layer product is made in a mold, it is necessary to form a layer and then wait for it to solidify before applying and solidifying a further layer. This is a time-consuming method and may result in color "bleed" between layers if the first layer is not completely solidified. Additionally, the nature of pouring liquid into a mold can result in inaccuracies in the layers dispensed.The present invention provides an improved product compared to such conventional systems.

[0100] The present invention may utilize any 3D printing process. In one embodiment, the present invention utilizes extrusion deposition. The detail / resolution that can be achieved in the product is determined (in part) by the thickness of each layer deposited. This is also related to the size / type of the print head of the 3D printer. In one embodiment, each layer of the solid cosmetic product deposited by 3D printing has a thickness of 10 mm or less. In one embodiment, at least two layers of the solid cosmetic product deposited by 3D printing have a thickness of 8 mm or less, preferably a thickness of 6 mm or less. In one embodiment, each layer of the solid cosmetic product deposited by 3D printing has a thickness of 8 mm or less, preferably a thickness of 6 mm or less. In one embodiment, at least two layers of the solid cosmetic product deposited by 3D printing have a thickness of 5 mm or less, preferably a thickness of 2 mm or less. In one embodiment, each layer of the solid cosmetic product deposited by 3D printing has a thickness of 5 mm or less, preferably a thickness of 2 mm or less. In one embodiment, at least two layers of the solid cosmetic product deposited by 3D printing have a thickness of 1 mm or less, preferably a thickness of 0.5 mm or less. In one embodiment, each layer of the solid cosmetic product deposited by 3D printing has a thickness of 1 mm or less, preferably 0.5 mm or less. In one embodiment, at least two layers of the solid cosmetic product deposited by 3D printing have a thickness of 0.2 mm or less, preferably 0.1 mm or less. In one embodiment, each layer of the solid cosmetic product deposited by 3D printing has a thickness of 0.2 mm or less, preferably 0.1 mm or less.

[0101] As will be appreciated from the advantages described herein, the present invention allows for the preparation of complex shapes of products that cannot be produced by other methods. Thus, in one aspect, the solid cosmetic composition has a shape that cannot be prepared by forming the solid cosmetic composition in a mold.

[0102] The solid cosmetic product may be formed into any suitable size product. The present invention allows for the preparation of small products that cannot be easily produced by conventional systems, such as molding, and for the preparation of large products that are extremely difficult to handle when produced by conventional systems. Thus, in one embodiment, the solid cosmetic composition has a mass of 1 g to 1000 kg, such as a mass of 1 g to 100 kg.

[0103] The shape of the bar product of the present invention is not limited. The bar product may be one that provides a shape that is aesthetically pleasing and / or aids in the use of the product. For example, the bar product may be a shape that is ergonomically acceptable to the user.

A product is provided which is obtained or obtainable by a process comprising:

[0110] In one embodiment, a cosmetic method comprising contacting a solid cosmetic composition prepared by 3D printing with the skin or hair of a user, the cosmetic composition comprising: (a) one or more vegetable butters in a total amount of 5 to 80% by weight (for example, a total amount of 20 to 80% by weight) based on the cosmetic composition; (b) one or more waxes in a total amount of 5 to 45% by weight based on the cosmetic composition; (c) one or more emulsifying materials in a total amount of 5 to 40% by weight based on the cosmetic composition; A cosmetic method is provided, comprising: [Example] EXAMPLES

[0111] The invention will now be described with reference to the following non-limiting examples.

[0112] [Table 1]

[0113] The above composition was formed into a base product according to the following method: 1. Melt A at 75℃. Check that the wax is melted. 2. Add C to B, stir and heat to 75°C. 3. Bring both A and B / C to 75°C and add B / C to A to emulsify. 4. Combine D and grind. 5. Gradually add D to A / B / C. 6. (Optional) Pour into molds and leave to set.

[0114] The base product was then 3D printed as follows: 1. Pre-heat the product syringe in a dehumidifier oven to approximately 32°C. 2. If using a solidified product, grind it into the preheated syringe. If the product is already molten, pour it into the preheated syringe. 3. Attach the syringe to the nozzle and set the syringe temperature controller to approximately 36°C. 4. Print according to the 3D printer settings below. Print speed: 150%, Layer height: 1.5; Print width: 1.5; Nozzle size: 1.5; Packing density: 100%; Extrusion speed: 0.8

[0115] The machine used was a byFlow Focus 3D Food printer. It was fitted with a machined aluminium nozzle, which had a heating controller around it, allowing precise control of the temperature of the syringe and deposition nozzle. It helped to achieve a consistent deposition and avoid hardening / blockage in the nozzle. We also found that initially the first few layers of the product were not adhering properly to the substrate. To address this, we used a pre-cooled granite substrate, which allowed the product to cool and solidify quickly on first contact, achieving a cleaner final product.

[0116] It took approximately 4 minutes to print an 8 g product having the shape of Figures 1a-1c.

[0117] The mascara product was applied by wetting a standard mascara brush with water and then inserting it into the hole in the cylinder. The mascara product was easily picked up by the brush and then applied to the user's eyelashes. The product was easily applied to the eyelashes without clumping and provided the desired cosmetic effect to the eyelashes. The product was worn by the user over a period of time, and no bleeding of the mascara product was observed. EXAMPLES

[0118] (comparison) The following comparative formulations were prepared using the following method.

[0119] [Table 2]

[0120] 1. Melt A at 75℃. Check that the wax is melted. 2. Prepare solution B. Heat to 75℃. 3. Add B to A and stir to gently emulsify. 4. Combine C and grind. 5. Gradually add C to A / B and pour into container.

[0121] The comparative formulation was then 3D printed using the method of Example 1.

[0122] The mascara product was applied by dipping a standard mascara brush into water and then inserting it into the hole in the cylinder. The mascara product was taken up by the brush and then applied to the user's eyelashes. The product was found to bleed easily onto the skin surrounding the eyelashes and required removal by the user. EXAMPLES

[0123] [Table 3]

[0124] Example 3 was prepared similarly to Example 2.
