Description

Technical Field

[0001] This specification discloses a cosmetic composition and a cosmetic comprising the cosmetic composition. Background Technology

[0002] Existing liquid cosmetic compositions are primarily distributed and stored in tubular containers, pump containers, or glass containers. However, since the development of dosage forms that impregnate cosmetic compositions in carriers, these carrier-impregnated cosmetics have become increasingly popular due to their portability and ease of use. For carrier-impregnated cosmetics, the filling power and flowability of the cosmetic composition are crucial, requiring appropriate flowability. However, with the diversification of cosmetic compositions prepared using carrier-impregnated dosage forms, some compositions containing flow-enhancing ingredients exhibit a tendency to tilt to one side when carrying the cosmetic, thus limiting their commercialization as carrier dosage forms. Summary of the Invention

[0003] Technical issues

[0004] The problem this disclosure aims to solve is to provide a cosmetic that improves the tilting phenomenon of the cosmetic composition that occurs during the carrying of the cosmetic or when the cosmetic is tilted for storage, when a cosmetic composition comprising bis-benzyl alcohol / isostearyl alcohol / phytosterol dimerlinoleic acid is provided in a dosage form impregnated in a carrier to improve skin gloss and adhesion.

[0005] Technical solution

[0006] To address the aforementioned problems, one embodiment of this disclosure provides a cosmetic product comprising: a cosmetic composition containing bis-benzyl alcohol / isostearyl alcohol / phytosterol dimeric linoleic acid dimeric linoleate and lithium montmorillonite-based oily thickener; and a carrier comprising a foam impregnated with the cosmetic composition.

[0007] Invention Effects

[0008] A cosmetic composition according to an embodiment of the present disclosure comprises bis-benzyl alcohol / isostearyl alcohol / phytosterol dimeric linoleic acid dimeric linoleate, thereby exhibiting good skin adhesion and skin radiance, while also exhibiting improved physical stability when provided in a dosage form impregnated in a carrier. Therefore, even when the cosmetic according to the present disclosure is stored horizontally or vertically, there is no problem of the composition tilting to one side or detaching from the carrier, resulting in excellent portability and storage properties.

[0017] Preferred embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0018] The embodiments disclosed herein are for illustrative purposes only. These embodiments can be implemented in various forms and should not be construed as being limited to those described herein. This disclosure can be modified and taken in various forms; therefore, the embodiments are not intended to limit this disclosure to a particular form, but should be understood to include all modifications, equivalents, and even substitutions within the concept and scope of this disclosure. Unless the context clearly specifies otherwise, singular expressions include plural expressions. In this application, terms such as "comprising" or "having" are intended to specify the presence of features, numbers, steps, operations, constituent elements, components, or combinations thereof described in the specification, and do not exclude the presence or additional possibilities of one or more other features or numbers, steps, operations, constituent elements, components, or combinations thereof.

[0019] One embodiment of this disclosure provides a cosmetic product comprising: a cosmetic composition containing bis-benzyl alcohol / isostearyl alcohol / phytosterol dimeric linoleic acid dimeric linoleate and lithium montmorillonite-based oily thickeners; and a carrier comprising a foam impregnated with the cosmetic composition.

[0020] In this disclosure, the bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate is a di-linoleyl alcohol di-linoleate whose terminals are replaced by a mixture of phytosterol, behenol, and isostearol. Due to its inherent viscosity, the bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate is primarily used in cosmetic formulations for localized areas such as the lips. Furthermore, when a composition containing bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate is impregnated or loaded into a foam, if tilting occurs during storage or use, it will not be stably impregnated in the foam and will tilt to one side, thereby reducing product quality; therefore, the formulation has limitations.

[0021] However, the present invention combines the aforementioned bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate with lithium montmorillonite-based oily thickeners, thereby providing the skin with gloss and improving its adhesion through the bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate, while also providing stability when the composition is contained in a foam, even when stored horizontally or vertically.

[0022] In one embodiment, the lithium montmorillonite-based oily thickener may include one or more selected from the group consisting of distearate dimethylammonium montmorillonite and stearalkonium hectorite.

[0023] In one embodiment, the bis-behenol / isostearyl / phytosterol dimer linoleic acid ester and the lithium montmorillonite-based oily thickener may be contained in a weight ratio of 0.25-1.5:1-1.5. Specifically, the bis-behenol / isostearyl / phytosterol dimer linoleic acid ester may contain 0.25 to 1.5% by weight relative to the total weight of the composition. More specifically, the bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate, relative to the total weight of the composition, may contain more than 0.25% by weight, more than 0.3% by weight, more than 0.4% by weight, more than 0.5% by weight, more than 0.6% by weight, more than 0.7% by weight, more than 0.8% by weight, more than 0.9% by weight, more than 1% by weight, more than 1.1% by weight, more than 1.2% by weight, more than 1.3% by weight, or more than 1.4% by weight, and may contain less than 1.5% by weight, less than 1.4% by weight, less than 1.3% by weight, less than 1.2% by weight, less than 1.1% by weight, less than 1% by weight, less than 0.9% by weight, less than 0.8% by weight, less than 0.7% by weight, less than 0.6% by weight, less than 0.5% by weight, less than 0.4% by weight, or less than 0.3% by weight. Specifically, the lithium montmorillonite-based oily thickener may contain 1 to 1.5% by weight relative to the total weight of the composition. More specifically, the lithium montmorillonite-based oily thickener may contain more than 1%, more than 1.1%, more than 1.2%, more than 1.3%, or more than 1.4% by weight relative to the total weight of the composition, or less than 1.5%, less than 1.4%, less than 1.3%, or less than 1.2% by weight. When the content of the lithium montmorillonite-based oily thickener is outside the aforementioned range and is low, the composition may tilt if the cosmetic is stored horizontally or vertically. When the content of the lithium montmorillonite-based oily thickener is too high, the viscosity of the composition may be too high and may be difficult to load into a foam.

[0024] In one embodiment, the viscosity of the cosmetic composition can be between 10,000 and 26,000 cps (centipoise). When the viscosity of the cosmetic composition is below 10,000 cps, the composition may tilt if stored horizontally or vertically; when it is above 26,000 cps, it may be difficult to formulate a dosage form impregnated in a foam. In one embodiment, the viscosity of the composition can be measured at 30°C. In one embodiment, the viscosity of the composition can be measured using a viscosity measuring device, for example, a DV3TLVTJ0 model (Btookfield) with a 64 rotor at 12 rpm. Alternatively, for example, an LVDV Ⅱ+PRO can be used with a 63 rotor at 5 rpm or a 64 rotor at 12 rpm.

[0025] In one embodiment, the cosmetic composition may be a liquid phase, a viscous solid phase, or a solid phase comprising powder; more specifically, it may be a liquid phase composition. In one embodiment, the dosage form of the cosmetic composition may include, but is not limited to, a solution, emulsion, gel, cream, suspension, or paste.

[0026] In one embodiment, the cosmetic composition may be one or more of the following: emulsified, water-in-oil, oil-in-water, oil-dispersed, water-dispersed, and solubilizing compositions. In one embodiment, the composition may be an oil-in-water type. The cosmetic composition may be formulated as, for example, a primer, sunscreen, liquid or solid foundation, BB cream, CC cream, concealer, lipstick, lip gloss, powder, lip liner, eyeliner, mascara, eyebrow pencil, eyeshadow, blush, two-tone powder, sunscreen, lotion, cream, or serum, but is not limited thereto. These compositions may be prepared according to conventional methods in the art.

[0027] Furthermore, the cosmetic composition according to an embodiment of this disclosure may also include functional additives and ingredients commonly found in conventional cosmetic compositions. As functional additives, these may include ingredients selected from the group consisting of water-soluble vitamins, oil-soluble vitamins, high-molecular-weight peptides, high-molecular-weight polysaccharides, sphingolipids, and seaweed concentrate. Other formulation ingredients may include oil components, moisturizers, emollients, neutralizers, surfactants, organic and inorganic pigments, organic powders, ultraviolet absorbers, preservatives, bactericides, antioxidants, plant extracts, pH adjusters, alcohols, pigments, fragrances, blood circulation promoters, cooling agents, antiperspirants, purified water, etc.

[0028] The cosmetic composition according to an embodiment of the present disclosure can be provided by impregnating a carrier containing a foaming body, and can provide a cosmetic that maintains high dosage form stability by preventing the contents from tilting to one side even when the contents are moved due to storage angle or movement.

[0029] In this disclosure, "carrier" refers to a substance capable of impregnating or loading any substance or ingredient (e.g., a composition), and may also be described as "load body," "impregnating material," "absorbent support," "absorbent," "discharge component," or "medium." Furthermore, a "carrier" can be used to discharge the substance loaded thereon into a separate application port. The composition loaded in the carrier can be delivered to the skin via application means (also called application tools or applicators) such as hands, powder puffs, pen tips, or brushes. Additionally, in this disclosure, "foam" as a material capable of impregnating or loading any substance or ingredient (e.g., a composition) refers to a material made of rubber, fiber, cotton, or resin that is shaped like a sponge and capable of loading and discharging cosmetic compositions.

[0030] In this disclosure, "loading capacity" refers to the ability to load and maintain any substance or ingredient. Regarding the "loading capacity" required for a carrier, it differs from the ability to temporarily remove the substance via an application tool, in that it allows for the uniform loading of the composition over a prolonged period. "Discharge capacity" or "discharge force" refers to the amount of cosmetic composition discharged when the cosmetic composition is removed from the foam containing the cosmetic composition via an application tool; preferably, an appropriate amount of cosmetic composition is discharged.

[0031] In one embodiment, the hardness of the foam can be between 50 and 100, based on the viewpoint of stably loading and discharging the cosmetic composition. If the hardness of the foam is below 50, the flowability is too high, which may cause the loaded cosmetic composition to tilt depending on the storage angle; if the hardness is above 100, the cosmetic composition may not be able to be smoothly filled and discharged. The hardness can be measured by placing an ASKER Type F hardness tester on the foam and taking the value after 5 seconds.

[0032] In one embodiment, the foam may have a thickness of 50 mm to 100 mm. If the thickness of the foam is less than 50 mm, the loading capacity of the cosmetic composition is low; if the thickness is greater than 100 mm, it may be difficult to discharge the cosmetic composition without residue during use.

[0033] In one embodiment, the foam is not particularly limited and can be a natural foam or a synthetic foam. For example, the natural foam can be made of materials such as sponge or natural rubber. For example, the synthetic foam can be made of materials selected from the group consisting of synthetic resins, polyurethane, latex, acrylonitrile-butadiene rubber (NBR), butadiene rubber (BR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), isoprene rubber (IIR), isoprene rubber (IR), ethylene propylene diene monomer (EPR), polysulfide rubber, silicone rubber, fluororubber, urethane rubber, acrylic rubber, ethylene propylene diene monomer (EPDM), polyvinyl alcohol (PVA), ethylene vinyl acetate (EVA), and nitrile rubber (NR).

[0034] In one embodiment, the polyurethane foam used as a type of foam is not particularly limited and may include polyether-based, polyester-based, or polycarbonate-based foamed polyurethane. In one embodiment, the polyether-based foamed polyurethane may include dry-process polyether-based foamed polyurethane, wet-process polyether-based foamed polyurethane, etc. In one embodiment, the polyester-based foamed polyurethane may include dry-process polyester-based foamed polyurethane, wet-process polyester-based foamed polyurethane, etc. In one embodiment, the polycarbonate-based foamed polyurethane may include dry-process polycarbonate-based foamed polyurethane, wet-process polycarbonate-based foamed polyurethane, etc.

[0035] In one embodiment, the method for absorbing the composition into the foam can be a method commonly used in the art. For example, absorption can be achieved by spraying, extrusion, or kneading the composition and the foam.

[0036] In one embodiment, the foam may include pores, and the cosmetic composition according to the embodiment may be impregnated in the pores of the foam and kept uniformly distributed in the carrier.

[0037] In one embodiment, the foam may contain 55-130 pores per inch (ppi). If the number of pores per inch of the foam is greater than 130 ppi, the small pore size makes it difficult to control the flowability, absorption, or release of the cosmetic composition; if the number of pores is less than 55 ppi, the loading capacity of the cosmetic composition may be reduced after loading. In this disclosure, "pore number" refers to the number of pores per inch of urethane foam. In this specification, the pore number may be an average value obtained by measuring the number of pores along a 1-inch horizontal line and a 1-inch vertical line using WI-QA-14 (ASTM standard).

[0038] In one embodiment, the carrier may further include a mesh on the upper part of the foam. Cosmetics containing only a foam as a carrier have a large initial release volume, making it difficult for the user to control the amount. However, as an embodiment, when a mesh is also included on the upper part of the foam, it has the advantage of allowing for the uniform use of a certain amount from the first application.

[0039] In one embodiment, the mesh may be in close contact with the foam or at a distance of 0.1 to 3.0 mm.

[0040] In one embodiment, the mesh, as a grid, a mesh body, or a net, follows the weave structure of the fabric and may be made of a porous material having stretch or elastic recovery along the left and right and / or up and down.

[0041] In one embodiment, the mesh may include one or more selected from the group consisting of nylon, polyester, polyurethane, acrylic acid, olefin, cotton, silk, PET, PE, PP, NBR, ester acetate, spandex, silicone rubber, thermoplastic elastomer (TPE), NHBR, fluororubber, synthetic fibers, and natural fibers.

[0042] In one embodiment, the shape of the mesh is not particularly limited and can be various shapes such as circles or polygons, depending on the shape of the final cosmetic.

[0043] In one embodiment, the thickness of the fibers constituting the mesh can be, for example, 2 to 100 μm. Fiber thickness includes measurements of fineness and width. As an embodiment, the mesh can be visually transparent.

[0044] As one embodiment, the weight of the mesh can be 80 to 300 g / yard.

[0045] In one embodiment, the mesh may further include a mesh frame, which may be formed, for example, of one or more selected from the group consisting of thermoplastic elastomers (TPEs), epoxy resins, acrylics, olefins, polyesters, and polyurethanes. In one embodiment, the mesh frame may be connected to the mesh by high-frequency welding or ultrasonic welding.

[0046] Furthermore, the cosmetic according to one embodiment may also include an application tool for removing the cosmetic composition from a foam carrier impregnated with the cosmetic composition. Additionally, as one embodiment, the cosmetic may also include a lower portion that accommodates the carrier and a mirror, and may also include a container with a lid, commonly referred to as a "pressed powder" cosmetic container, but is not limited thereto.

[0047] The present disclosure will now be described in more detail through the following embodiments. However, the following embodiments are provided for illustrative purposes only to aid in understanding the present disclosure, and the scope and extent of the disclosure are not limited thereto.

[0048]

Experimental Example 1

[0049] According to one embodiment of this disclosure, a cosmetic is prepared by impregnating a cosmetic composition in a carrier containing a foaming body, and it is confirmed whether the contents tilt when the carrier is stored horizontally or vertically.

[0050] The compositions used in the experiments were prepared according to the components listed in Table 1 below using conventional methods in the art. 15 g of each composition was impregnated into a polyurethane foam with a hardness of 90 and a ppi of 90 or higher using conventional methods in the art to prepare the final cosmetic dosage form. The viscosity of each composition was measured at 30°C using a DV3TLVTJ0 model (Btookfield) with a 64 rotor at 12 rpm, and the results are shown in Table 1 below.

[0051] Each of the prepared cosmetics was placed sideways in an oven at 55°C, and after one day, the composition was checked for tilting, as shown in Table 1 below. Figures 1 to 6 Each photo is shown in the image.

[0052] Table 1

[0053]

[0054] The results show that no tilting of the cosmetic composition occurred in Examples 1-3 according to an embodiment of this disclosure (see reference). Figures 1 to 3 However, in Comparative Example 1, which uses waxes, a common thickener in cosmetics, increased fluidity resulted in severe tilting (see reference). Figure 4 Furthermore, in Comparative Examples 2 to 4, which contained less than 1% by weight or more than 1.5% by weight of lithium montmorillonite-based oily thickeners, composition tilting also occurred (see reference). Figure 5 and Figure 6 ).

[0055]

Experimental Example 2

[0056] As an embodiment of this disclosure, a cosmetic product in which the carrier includes a mesh in addition to the foam (Example 4) was prepared, and its effect on improving the uniformity of discharge over time was compared with that of Example 1 in Test Example 1.

[0057] Example 4 uses the same composition and foam as Example 1 and is prepared by the same method, except that a mesh (nylon mesh containing spandex) is added to the upper end of the foam.

[0058] The amount dispensed per use (one-time effect) is measured by weighing the amount of product picked up by the powder puff (application tool) and under conditions similar to those used by the user, as if the product were actually being used. Based on the amount dispensed, the usage period is divided into the following stages: Early Use (Initial): A suitable amount of product can be dispensed onto the puff without applying pressure; Unsatisfactory Use (Mid-Stage): The amount of product dispensed is small or uneven when not applying pressure; Squeeze Use: Little product is dispensed when not applying pressure, making makeup application inconvenient or requiring more force to apply product.

[0059] The result, such as Figure 7 and Figure 8 As shown, in Example 1, the average usage per application was 0.069g, while in Example 4, the average usage per application was 0.053g, indicating a difference. Example 4 showed a higher number of applications. In conclusion, it was confirmed that the form of Example 4, which also included a mesh compared to Example 1, could be used with a more uniform amount for a longer period of time.
