Description

Technical Field

[0001] In this specification, a cosmetic composition and a cosmetic containing the same are disclosed.

Background Art

[0002] Conventional liquid cosmetic compositions have mainly been filled in tube containers, pump containers, or glass containers for distribution and storage. However, since the development of preparations impregnating a cosmetic composition into a carrier, due to portability and ease of use, cosmetics of preparations impregnating a cosmetic composition into a carrier have gradually become popular. For cosmetics of preparations impregnating a cosmetic composition into a carrier, the filling power and discharging power of the cosmetic composition with respect to the carrier are important, and for this purpose, appropriate fluidity is required. However, as the types of cosmetic compositions manufactured as carrier-impregnated preparations diversify, in some cases of cosmetic compositions containing components for enhancing fluidity, when carrying the cosmetics, there is a problem that the cosmetic composition is unevenly distributed to one side, and there has been a limit to commercialization as a carrier preparation.

[0008] Preferred embodiments of this disclosure will be described in detail below with reference to the attached drawings.

[0009] The examples of the Disclosure disclosed herein are illustrative for illustrative purposes only, and the examples of the Disclosure can be implemented in various forms and should not be construed as being limited to the examples described herein. Since the Disclosure can be modified in various ways and may take various forms, the examples should not be understood as being intended to limit the Disclosure to any particular form of disclosure, but rather as including any modifications, equivalents or substitutes that fall within the idea and technical scope of the Disclosure. Unless otherwise specified, singular expressions include plural expressions. Terms such as “includes” and “has” in this application indicate the presence of features, figures, steps, operations, components, parts or combinations thereof described in the specification, but do not preclude the presence or possibility of adding one or more other features, figures, steps, operations, components, parts or combinations thereof.

[0010] One embodiment of the present invention provides a cosmetic product comprising a cosmetic composition containing bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate and a hectorite-based oil thickener, and a carrier containing a foamed foam in which the cosmetic composition is impregnated.

[0011] In the present invention, the bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate is a mixture of phytosterol, behenyl alcohol, and isostearyl alcohol, and is a dimer dilinoleyl dimer dilinoleate with a substituted terminal. Due to the sticky properties inherent in the components, the bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate has been mainly used as a makeup formulation for localized areas such as the lips. Furthermore, compositions containing bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate have a limitation in formulation because, when impregnated or supported in foam, if tilted during storage or use, the impregnation does not stably occur within the foam and becomes biased to one side, reducing the quality of the product.

[0012] However, the present invention provides a combination of bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate with a hectorite-based oil thickener, thereby exhibiting glossiness and improving adhesion to the skin, as well as providing stability so that the composition does not become unevenly distributed even when stored horizontally after being impregnated into foam.

[0013] In one embodiment, the hectorite-based oil thickener may include at least one selected from the group consisting of disteardimonium hectorite and stearalkonium hectorite.

[0014] In one embodiment, the bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate and the hectorite-based oil thickener may be present in a weight ratio of 0.25 to 1.5:1 to 1.5. Specifically, the bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate may be present in an amount of 0.25 to 1.5% by weight relative to the total weight of the composition. More specifically, dimer dilinoleyl bis-behenyl / isostearyl / phytosteryl dimer dilinoleate may be present in amounts of 0.25% or more by weight, 0.3% or more by weight, 0.4% or more by weight, 0.5% or more by weight, 0.6% or more by weight, 0.7% or more by weight, 0.8% or more by weight, 0.9% or more by weight, 1% or more by weight, 1.1% or more by weight, 1.2% or more by weight, 1.3% or more by weight, or 1.4% or more by weight, and may be present in amounts of 1.5% or less by weight, 1.4% or less by weight, 1.3% or less by weight, 1.2% or less by weight, 1.1% or less by weight, 1% or less by weight, 0.9% or less by weight, 0.8% or less by weight, 0.7% or less by weight, 0.6% or less by weight, 0.5% or less by weight, 0.4% or less by weight, or 0.3% or less by weight, based on the total weight of the composition. Specifically, the hectorite-based oil thickener may be present in an amount of 1 to 1.5% by weight relative to the total weight of the composition. More specifically, the hectorite-based oil thickener may be present in an amount of 1% or more by weight, 1.1% or more by weight, 1.2% or more by weight, 1.3% or more by weight, or 1.4% or more by weight relative to the total weight of the composition, and may be present in an amount of 1.5% or less by weight, 1.4% or less by weight, 1.3% or less by weight, or 1.2% or less by weight. If the amount of the hectorite-based oil thickener is small and outside the above range, there is a risk that the composition may become unevenly distributed when the cosmetic is stored horizontally, and if the amount of the hectorite-based oil thickener is excessive, the viscosity of the composition may become too high, making it difficult to support on the foam.

[0015] In one embodiment, the viscosity of the cosmetic composition may be 10,000 to 26,000 cps (centi poise). When the viscosity of the cosmetic composition is less than 10,000 cps, there may be a problem of uneven distribution of the composition when stored horizontally, and when it exceeds 26,000 cps, it may be difficult to manufacture it as a formulation impregnated into a foaming foam. In one embodiment, the viscosity of the composition may be measured at 30°C. In one embodiment, the viscosity of the composition can be measured with a viscosity measuring device. For example, it can be measured under the conditions of spindle No. 64 and 12 rpm using a DV3TLVTJ0 model (manufactured by Brookfield). Or, for example, it can be measured with an LVDVII+PRO at spindle No. 63, spindle speed 5 rpm, or spindle No. 64, spindle speed 12 rpm, etc.

[0016] In one embodiment, the cosmetic composition may be liquid, solid with viscosity, or solid containing powder, and more specifically, it may be a liquid composition. In one embodiment, examples of the formulation of the cosmetic composition include, but are not limited to, solutions, emulsions, gels, creams, suspensions, or paste formulations.

[0017] In one embodiment, the cosmetic composition may be any one or more of an emulsion type, water-in-oil type, oil-in-water type, oil dispersion, water dispersion, and solubilized composition. In one embodiment, the composition may be a water-in-oil type. The cosmetic composition can be formulated, for example, as a makeup primer, makeup base, liquid or solid foundation, BB cream, CC cream, concealer, lipstick, lip gloss, powder, lip liner, eyeliner, mascara, eyebrow, eyeshadow, blusher, powder foundation, sunscreen, lotion, cream, or essence, etc., but is not limited thereto. These compositions may be manufactured according to ordinary methods in the art.

[0018] In addition, the cosmetic composition according to an embodiment of the present invention may further contain functional additives and components contained in general cosmetic compositions. The functional additive may include components selected from the group consisting of water-soluble vitamins, oil-soluble vitamins, high-molecular-weight peptides, high-molecular-weight polysaccharides, sphingolipids, and seaweed extracts. Other compounding components include oil and fat components, humectants, emollients, neutralizing agents, 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, and the like.

[0019] The cosmetic composition according to an embodiment of the present invention can be provided by impregnating a carrier containing a foamed foam, and can provide a cosmetic that can maintain high formulation stability without the contents being biased to one side due to the storage angle of the cosmetic or the movement during transportation.

[0020] The "carrier" in the present invention means any substance or component that can impregnate or carry a composition that can be exemplified, and can also be represented by a "support", "impregnating material", "absorbent support", "absorbent", "discharge member", or "medium". Further, the "carrier" may be used to discharge the substance supported thereon to a separate applicator. The composition supported on the carrier can be applied to the skin by application means such as hands, puffs, chips, brushes (also referred to as "applicators" or "applicators"). Further, the "foamed foam" in the present invention is a material that can impregnate or carry any substance or component that can be exemplified by the composition, and is a sponge-like formation of rubber, fiber, cotton, or resin, and means that it can carry and discharge the cosmetic composition.

[0021] Here, "carrying capacity" in the present invention means the ability to contain and hold any substance or component. The "carrying capacity" required of a carrier is distinguished from cases where a substance is temporarily taken up by an applicator, etc., as it means uniformly carrying the composition for a long period of time. Furthermore, "discharge capacity" or "discharge force" means the amount of cosmetic composition discharged when the cosmetic composition is applied by an applicator from the foam carrying the cosmetic composition, and it is preferable that an appropriate amount of cosmetic composition, neither too much nor too little, is discharged.

[0022] In one embodiment, the hardness of the foam may be 50 to 100 from the viewpoint of stably supporting and discharging the cosmetic composition. If the hardness of the foam is less than 50, the fluidity will be excessive, and there is a risk that the supported cosmetic composition will be unevenly distributed depending on the storage angle. If it exceeds 100, the filling and discharging of the cosmetic composition may not be performed properly. The hardness may be measured by placing an ASKER type F hardness tester on the foam and measuring the value after 5 seconds.

[0023] In one embodiment, the thickness of the foamed foam may be 50 to 100 mm. If the thickness of the foamed foam is less than 50 mm, the amount of cosmetic composition it can hold will be small, and if it exceeds 100 mm, it may be difficult to discharge the cosmetic composition if there is no remaining contents at the time of use.

[0024] In one embodiment, the foamed foam is not particularly limited and may be natural foamed foam or synthetic foamed foam. For example, the natural foamed foam may be made of materials such as sponges or natural rubber. For example, the material of the synthetic foamed foam may include at least one selected from the group consisting of synthetic resin, polyurethane, latex, acrylonitrile-butadiene rubber (NBR), butadiene rubber (BR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), butyl rubber (isoprene-isobutylene rubber; IIR), isoprene rubber (IR), vulcanized ethylene-propylene rubber (EPR), polysulfide rubber, silicone rubber, fluororubber, urethane rubber, acrylic rubber, EPDM (Ethylene propylene diene monomer) rubber, polyvinyl alcohol (PVA), ethylene vinyl acetate (EVA), and NR (Nitrile Rubber).

[0025] In one embodiment, the polyurethane foam foam, which is a type of foam foam, is not particularly limited, but may include polyether-based polyurethane foam, polyester-based polyurethane foam, or polycarbonate-based polyurethane foam. In one embodiment, the polyether-based polyurethane foam may include polyether-based dry-laid polyurethane foam, polyether-based wet-laid polyurethane foam, etc. In one embodiment, the polyester-based polyurethane foam may include polyester-based dry-laid polyurethane foam, polyester-based wet-laid polyurethane foam, etc. In one embodiment, the polycarbonate-based polyurethane foam may include polycarbonate-based dry-laid polyurethane foam, polycarbonate-based wet-laid polyurethane foam, etc.

[0026] In one embodiment, the method for absorbing the composition into the foam may be a method commonly used in the art. For example, absorption can be achieved by spraying, pressing, or mixing the composition with the foam.

[0027] In one embodiment, the foam may contain pores, and the cosmetic composition according to the embodiment can be impregnated into the pores of the foam and remain uniformly distributed on the carrier.

[0028] In one embodiment, the foam may contain 55 to 130 pores (ppi) per inch. If the number of pores per inch of the foam exceeds 130 ppi, the pore size becomes too small, making it difficult to control the fluidity, absorption, or discharge of the cosmetic composition. If it is less than 55 ppi, the load-bearing capacity for the cosmetic composition may decrease after the cosmetic composition is loaded. In the present invention, the "number of pores" refers to the number of pores per inch of the urethane foam, and the number of pores as used herein may be an average value obtained by measuring the number of pores on a 1-inch line vertically and horizontally using WI-QA-14 (ASTM standard).

[0029] In one embodiment, the carrier may further include a mesh net on top of the foam. In the case of cosmetics containing only foam as a carrier, the initial dispensing amount is large, and it may be difficult for the user to control the dispensing amount. However, in one embodiment, when a mesh net is further included at the top of the foam, there is the advantage that a uniform and consistent amount can be used from the first use.

[0030] In one embodiment, the mesh may be in close contact with the foam or located at a distance of 0.1 to 3.0 mm.

[0031] In one embodiment, the mesh, net, or net may be formed of a porous material that has elasticity or resilience in the left-right and / or up-down directions, according to the weave structure of the base fabric.

[0032] As one embodiment, the mesh may include at least one selected from the group consisting of nylon, polyester, polyurethane, acrylic, olefin, cotton, silk, PET, PE, PP, NBR, acetate, spandex, silicone rubber, TPE (thermoplastic elastomer), NHBR, fluororubber, synthetic fibers, and natural fibers.

[0033] As one embodiment, the shape of the mesh is not particularly limited, and various shapes such as circular or polygonal are possible depending on the final shape of the cosmetic product.

[0034] In one embodiment, the thickness of the fibers constituting the mesh network may be, for example, 2 to 100 μm. The thickness of the fibers includes measurements of the thinner end and the thicker end. In one embodiment, the mesh network may have visual transparency.

[0035] In one embodiment, the weight of the mesh net may be 80 to 300 g / yard.

[0036] In one embodiment, the mesh net may further include an edge portion, which may be made of at least one selected from the group consisting of thermoplastic elastomer (TPE), epoxy, acrylic, olefin, polyester, and polyurethane. In one embodiment, the edge portion of the mesh net may be connected to the mesh net by high-frequency fusion or ultrasonic fusion.

[0037] Furthermore, the cosmetic according to the above embodiment may further include an applicator for taking the cosmetic composition from a foam carrier impregnated with the cosmetic composition. Also, as an embodiment, the cosmetic may further include a lower part and a mirror capable of housing the carrier, and may further include a container including a lid, a cosmetic container generally called a case, but is not limited to these.

[0038] The present invention will be described in more detail below with reference to the following examples. However, the following examples are merely illustrative to aid in understanding the present invention, and the scope and nature of the present invention are not limited thereto.

[0039] [Test Example 1] In one embodiment of the present invention, a cosmetic product was manufactured by impregnating a carrier containing foam with a cosmetic composition, and it was confirmed whether or not a phenomenon of uneven distribution of contents occurred when the product was stored horizontally.

[0040] Each composition used in the test was manufactured according to conventional manufacturing methods in the art, according to the compositions shown in Table 1 below. 15 g of each composition was impregnated into polyurethane foam with a hardness of 90 and ppi of 90 or higher according to conventional methods in the art to produce a final cosmetic formulation. The viscosity of each composition was measured at 30°C using a DV3TLVTJ0 model (Btookfield) with a spindle number 64 and a speed of 12 rpm. The results are shown in Table 1 below.

[0041] Each of the manufactured cosmetics was placed horizontally in a 55°C oven, and after one day, it was checked whether or not the composition had become unevenly distributed. The results are shown in Table 1 below. The images for each product are shown in Figures 1 to 6.

[0042] [Table 1]

[0043] As a result, while Examples 1 to 3, according to one embodiment of the present invention, did not exhibit the phenomenon of uneven distribution of the cosmetic composition (see Figures 1 to 3), Comparative Example 1, which used wax, a thickening agent commonly used in cosmetics, showed increased fluidity and a significant phenomenon of uneven distribution (see Figure 4). Furthermore, in Comparative Examples 2 to 4, which contained less than 1% by weight of hectorite-based oil thickening agent or more than 1.5% by weight, the phenomenon of uneven distribution of the composition was also observed (see Figures 5 and 6).

[0044] [Test Example 2] As one embodiment of the present invention, a cosmetic product (Example 4) was manufactured that further included a mesh net in addition to foamed foam as a carrier, and the effect of improving discharge uniformity according to the period of use was compared with Example 1 of Test Example 1.

[0045] Example 4 was manufactured using the same composition and foam as Example 1, and in the same manner, except that a mesh net (spandex-containing nylon mesh) was added to the upper edge of the foam.

[0046] The amount dispensed per use (per payoff) was measured by the weight of the contents picked up by the puff (applicator), using the actual product under conditions similar to how users would use it. The usage period was divided according to the amount dispensed: the mild usage period (initial stage) was when an appropriate amount of contents adhered to the puff without applying force when picking up the contents; the unsatisfactory usage period (mid-stage) was when the amount picked up when picking up the contents without force was small, or when the contents did not adhere evenly to the puff; and the squeeze usage period was when the amount dispensed when picking up the contents without force was small, causing inconvenience in applying makeup, or when the contents did not adhere without applying force.

[0047] As a result, as shown in Figures 7 and 8, the average amount used per use was 0.069 g in Example 1, compared to 0.053 g in Example 4, indicating a higher payoff rate in Example 4. Overall, it was confirmed that the configuration of Example 4, which further includes a mesh net, allows for the use of a more uniform amount for a longer period than Example 1.
