Description

Technology Field

[0001] The present invention relates to a shea butter-based preservative-free cosmetic composition and a shea butter-based preservative-free cosmetic containing the same. More specifically, the invention provides a natural, highly moisturizing cosmetic that is based on shea butter containing active ingredients without using any chemical solvents and does not require preservatives by not including purified water, thereby allowing it to be used safely for skin care, especially on sensitive skin, and to a shea butter-based preservative-free cosmetic containing the same. Background Technology

[0003] Skin cosmetics are composed of ingredients that easily serve as optimal nutrients for the proliferation of microorganisms; therefore, microbial contamination must be prevented to maintain and preserve the quality of the cosmetics.

[0004] Generally, cosmetics have been preserved by using synthetic preservatives to prevent microbial contamination, such as para-hydroxybenzoic acid esters, imidazoridyl urea, salicylic acid, and benzyl alcohol.

[0005] However, the use of currently used synthetic preservatives is restricted in terms of type and content due to problems such as causing contact dermatitis or stimulating the central nervous system to induce collapse, extreme hypothermia, and convulsions, and recently, active technological development is underway to reduce the use of preservatives.

[0006] Meanwhile, due to environmental changes such as air pollutants resulting from recent industrialization and changes in dietary habits, many natural materials are continuously being discovered, and their scope of application is expanding.

[0007] Furthermore, as a cosmetic, skin hazards caused by lifestyle factors such as facial cleansing and bathing, as well as ingredients containing chemicals, are gradually increasing. Due to these changes, the rate of formation and shedding of the stratum corneum slows down, and the decline in the function of keratinocytes leads to a decrease in moisturizing factors in the stratum corneum, resulting in symptoms of skin dryness and significantly lowering the skin barrier function.

[0008] Research and development are underway on cosmetic materials containing natural ingredients to protect the skin from the aforementioned harmful factors, supply moisture from the outside for proper skin hydration, and prevent moisture loss from the body. Prior art literature

On the other hand, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between.

[0037] The terms used in this specification are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as "comprising" or "having" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0038] Additionally, terms such as "...part," "...unit," and "...module" as described in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware, software, or a combination of hardware and software.

[0039] Furthermore, in the description referring to the attached drawings, identical components are assigned the same reference numeral regardless of drawing symbols, and redundant descriptions thereof are omitted. In describing the present invention, if it is determined that a detailed description of related prior art could unnecessarily obscure the essence of the present invention, such detailed description is omitted.

[0040] Hereinafter, a shea butter-based preservative-free cosmetic composition according to a preferred embodiment of the present invention and a shea butter-based preservative-free cosmetic containing the same will be described in detail.

[0041] The shea butter-based preservative-free cosmetic composition according to the present invention and the shea butter-based preservative-free cosmetic containing the same comprise shea butter (Butyrospermum Parkii (Shea) Butter), microcrystalline wax, one or more natural oils, an antioxidant, and a fragrance (Parfum).

[0042] The shea butter mentioned above provides moisture to rough and dry skin, making it hydrated. It is a plant-based oil with powerful anti-inflammatory effects extracted from the inner seeds of the shea tree (shea nut), and its scientific name is Butyrospermum parkii. Shea butter is a slightly yellow fatty acid extract, with 25–30% of its composition consisting of antioxidant (phenolic) components. It is rich in beneficial biochemical active ingredients such as natural vitamins (A, D, E, F), phytosterols with anti-inflammatory and immune-modulating properties, polyphenols, and tocopherols. Due to its excellent antioxidant and anti-inflammatory functions, it is known to have a soothing effect, particularly on atopic inflammation.

[0043] Shea butter has physical and chemical properties very similar to beef tallow and exists as a semi-solid substance like butter at room temperature. Due to its physical properties, it presents a problem of being very inconvenient for practical application. Furthermore, shea butter extracted by conventional methods contains a large amount of impurities, making it difficult to secure high-quality shea butter.

[0044] In the present invention, the shea butter is a major component having a content ratio of more than half, i.e., 50% by weight or more, of the total cosmetic composition of 100% by weight. In the present invention, the shea butter used is obtained through a specific process without using any chemical solvents, and this is explained in detail below after the description of other compositions.

[0045] The above-mentioned microcrystalline wax is a type of solid wax extracted from petroleum, which has high viscosity and soft, flexible characteristics. Compared to other waxes, it has strong stickiness, allowing it to combine well with other components and effectively block moisture, thus providing moisturizing or waterproofing effects. It also has a relatively low melting point and a high boiling point, allowing it to be used stably at various temperatures.

[0047] Next, it is preferable that one or more of the above natural oils are vegetable natural oils.

[0048] In the present invention, the natural oil preferably includes castor seed oil (Ricinus Communis (Castor) Seed Oil), hydrogenated castor oil (Hydrogenated Castor Oil), apple seed oil (Pyrus Malus (Apple) Seed Oil), camellia seed oil (Camellia Japonica Seed Oil), hydrogenated coconut oil (Hydrogenated Coconut Oil), sunflower seed oil (Helianthus Annuus (Sunflower) Seed Oil), and rice bran oil (Oryza Sativa (Rice) Bran Oil).

[0049] delete

[0050] Specifically, when all of the above-mentioned natural oils are included, the composition may contain 50 to 58 parts by weight of castor seed oil, 18 to 24 parts by weight of hydrogenated castor oil, 1 to 3 parts by weight of apple seed oil, 1 to 3 parts by weight of camellia seed oil, 1 to 3 parts by weight of hydrogenated coconut oil, 0.01 to 1 part by weight of sunflower seed oil, and 0.01 to 1 part by weight of rice bran oil, based on 100 parts by weight of shea butter.

[0051] Furthermore, it is preferable that the above antioxidant be tocopherol.

[0052] Tocopherol is known to be effective in neutralizing free radicals to prevent damage to skin cells, helping to slow down the skin aging process, supplying moisture to the skin and enhancing moisturizing effects to help keep dry skin hydrated, and alleviating skin inflammation and reducing redness and irritation.

[0053] And the fragrance (Parfum) may be at least one selected from Benzyl Salicylate, Linalool, Coumarin, Alpha-Isomethyl Ionone, Limonene, and Geraniol.

[0055] Meanwhile, as previously mentioned, in the present invention, shea butter is a major component having a content ratio of more than half (i.e., a content ratio of more than 50 weight%) of 100 weight% of the total cosmetic composition. In the present invention, shea butter obtained through a specific process without using any chemical solvents is utilized, and this will be explained in detail with reference to FIGS. 1 to 6.

[0056] FIG. 1 is a flowchart schematically showing the process for obtaining shea butter included in the shea butter-based preservative-free cosmetic composition according to the present invention, FIG. 2 is a diagram schematically showing the final acquisition process for obtaining shea butter included in the shea butter-based preservative-free cosmetic composition according to the present invention, and FIG. 3 is a photograph of shea butter included in the shea butter-based preservative-free cosmetic composition according to the present invention, where (A) is a photograph of the state before decolorization (refining) and (B) is a photograph of the state after decolorization (refining). FIG. 4 is a photograph of the cooled state of the shea butter obtained through the process of FIG. 1, where (A) is a photograph of the state before decolorization (refining) and (B) is a photograph of the state after decolorization (refining). FIG. 5 is a photograph of the final acquisition process of shea butter included in the shea butter-based preservative-free cosmetic composition according to the present invention, where (A) and (B) are photographs of a non-woven fabric filter placed on a filter member having a diatomaceous earth filter layer, and (C) is a photograph of the process of filtering a mixing mixture through a non-woven fabric filter. FIG. 6 is a photograph of the manufacturing process of a filter member used in the acquisition process of shea butter included in the shea butter-based preservative-free cosmetic composition according to the present invention.

[0057] The shea butter included in the shea butter-based preservative-free cosmetic composition according to the present invention is obtained by extraction without using a chemical solvent, and as shown in FIGS. 1 to 6, comprises: a shea nut sorting step (S100) for sorting shea nuts harvested from a shea tree; a shea nut pretreatment step (S200) for pretreating shea nuts, including treatment such as removing impurities contained in the shea nuts sorted in the shea nut sorting step (S100); a shea nut grinding step (S300) for grinding the shea nuts pretreated in the shea nut pretreatment step (S200) using a grinding device (or grinder); and a shea nut oil extraction step (S400) for obtaining a shea nut oil by extracting the ground shea nuts obtained in the shea nut grinding step (S300) one or more times at a predetermined temperature or within a predetermined temperature range using an oil press. and a shea butter acquisition step (S500) in which the shea nut extract obtained by extracting in the shea nut extraction step (S400) is refined or decolorized using a refining means to obtain shea butter having a predetermined color (e.g., off-white or ivory).

[0058] The above shea nut selection step (S100) is a process of selecting shea nuts suitable for obtaining shea butter from shea nuts harvested from a shea tree, and can be accomplished by naturally drying the harvested shea nuts and then selecting high-quality shea nuts.

[0059] Furthermore, the shear nut pretreatment step (S200) is a process of pretreating the shear nuts selected in the shear nut selection step (S100) to obtain high-quality shea butter, including treatments such as removing impurities.

[0060] The above pretreatment step (S200) includes a process for removing dust, stones, metal fragments, etc. present with the shear nut.

[0061] For example, the above pretreatment step (S200) includes, first, removing dust from the shear nut; second, removing stones and the like that present with the shear nut; third, removing metal fragments and the like that generated by the collecting device when collecting the shear nut; and clearly confirming the state of impurity removal of the shear nut after removal is complete through visual inspection and mechanical devices so that only the shear nut to be crushed in the next process remains.

[0062] Next, the shear nut crushing step (S300) is a process of crushing the shear nut pretreated in the shear nut pretreatment step (S200) using a crushing device (or crusher).

[0063] The above shear nut grinding step (S300) grinds the nut to have a predetermined hardgrove grindability index using a grinder or grinding device, such as a ball mill, for example.

[0064] In the present invention, the shear nut grinding step (S300) is preferably performed such that the shear nut is ground to have a particle size of 0.1 mm to 12 mm, preferably a grinding particle size (grinding degree) of 1 mm to 2 mm.

[0065] The grinder or grinding device used to grind the shear nut in the above shear nut grinding step (S300) may be a known one capable of grinding to have the above-mentioned grinding degree (or grinding particle size).

[0066] Next, the shear nut extraction step (S400) is a process of obtaining a shear nut extract by extracting the crushed shear nut material obtained in the shear nut crushing step (S300) at least once at a predetermined temperature or within a predetermined temperature range using an oil extractor (or oil extraction device).

[0067] The above shear nut oil extraction step (S400) is performed by using an oil extractor to extract oil from crushed shear nuts in an oil extraction environment having a predetermined temperature, preferably a relatively low temperature compared to conventional high temperatures, i.e., a temperature of 70℃ to 80℃.

[0068] The extraction method used in this shea nut extraction step (S400) is a relatively low-temperature extraction method. Unlike conventional extraction (extraction) methods that use high-temperature pressing and may generate carcinogens such as benzopyrene, this method is designed to preserve the omega-3 components in the extracted shea nut by using low-temperature pressing without the use of solvents.

[0069] It is preferable that the above shear nut oil extraction step (S400) be performed two or more times in the above-mentioned oil extraction temperature environment (temperature of 70℃ to 80℃).

[0070] And the oiling machine or oiling device used in the above-mentioned shear nut oiling step (S400) is a known oiling machine or oiling device, wherein the oiling machine or oiling device configured to have the above-mentioned temperature value or temperature range is used.

[0071] The shea nut oil obtained in the above shea nut oil extraction step (S400) has a color such as (B) in FIG. 2 or (A) in FIG. 3.

[0072] Next, the shea butter acquisition step (S500) is a process of obtaining shea butter having a predetermined color (e.g., off-white or ivory) by refining or decolorizing the liquid shea nut extract obtained by extraction in the shea nut extraction step (S300) using a refining means.

[0073] Specifically, the shea butter acquisition step (S500) comprises a shea nut extract heating step (S510) for heating the shea nut extract to a predetermined temperature, a purification mixture input-mixing step (S520) for introducing a carbon-based powdered decolorizing (purification) mixture into the shea nut extract heated in the shea nut extract heating step (S510), mixing and mixing to prepare a mixing mixture, and a purification step (S530) for purifying (decolorizing) the mixing mixture prepared in the purification mixture input-mixing step (S520) by filtering it using a diatomaceous earth-based filter member.

[0074] The above shear nut oil heating step (510) consists of heating the liquid or solid shear nut oil at a temperature of 70°C to 80°C, preferably 75°C to 77°C, while stirring using a rotary stirring device (preferably at 100 rpm).

[0075] And the above purification mixture addition-mixing step (S520) is a process of adding a carbon-based powdered decolorization (purification) mixture to the shea nut oil heated in the above shea nut oil heating step (S510), mixing, and mixing to prepare a mixing mixture. This is accomplished by mixing 0.5 parts by weight of activated carbon powder, preferably palm activated carbon powder, as the carbon-based powdered decolorization (purification) mixture with 100 parts by weight of the shea nut oil, stirring for 10 minutes (preferably at 300 rpm), stirring at 100 rpm for 30 minutes, and then maintaining a state without stirring for 1 hour.

[0076] The above-mentioned purification mixture input-mixing step (S520) involves adding and mixing activated carbon powder, which is a carbon-based powdered decolorizing (purification) mixture, thereby allowing impurities and color substances from the shea nut extract to be absorbed by the activated carbon, while also absorbing the rich scent of shea butter and maintaining the unique scent of the shea nut to some extent.

[0077] It is preferable that the activated carbon used in the above-mentioned purification mixture input-mixing step (S520) has a particle size of 0.075 mm or less, an ash content of 8 or less, and a pH of 9-11.

[0078] Furthermore, the purification step (530) is a process of purifying (decolorizing) the mixing mixture prepared in the purification mixture input-mixing step (S520) by filtering it using a diatomaceous earth-based filter member.

[0079] The above purification step (S530) is performed by filtering the mixing mixture using a diatomaceous earth-based filter member by vacuum filtration, that is, by operating the pressure inside the filter bed filled with filter sand to be lower than atmospheric pressure.

[0080] The above-mentioned diatomaceous earth-based filter material is preferably prepared by mixing distilled water and diatomaceous earth in a ratio of 1:0.15 to 0.17 (i.e., 4.5 to 5 g of diatomaceous earth in 30 ml of distilled water), pouring the mixture onto a nonwoven filter, and applying reduced pressure to ensure that the diatomaceous earth is evenly coated on the nonwoven filter. At this time, the reduced pressure time is preferably 10 minutes.

[0081] Then, after depressurization, drying is performed in a dryer at 60°C for 40 minutes to 1 hour, followed by drying at room temperature for at least 30 minutes.

[0082] It is preferable that the diatomaceous earth applied to the above nonwoven filter be applied to a thickness of 3 to 4 mm. Here, if the application amount is 5 mm or more, the loss amount of shear nut adhesions increases and the filtration time becomes long, and if the application amount is less than 2 mm, not only is filtration not achieved, but there is also a problem that the durability of the nonwoven filter material decreases during the process of filtering the mixing mixture mixed with activated carbon, requiring frequent replacement.

[0083] In other words, applying diatomaceous earth to a thickness of 3 to 4 mm effectively purifies the mixed mixture containing activated carbon, while also increasing the durability of the nonwoven filter and extending its service life.

[0084] In addition, the diatomite coated on the nonwoven filter in the purification step (S530) is preferably diatomite having a particle size of 46 to 49 microns, a pH of 9.2, a specific gravity of 2.3, a permeability of 5.6 to 5.9, and a silica (SiO2) content of 89% to 89%.

[0085] The shea butter product obtained in the above-mentioned shea butter acquisition step (S400) is packaged in a liquid or solid state, cooled, transferred to a storage warehouse, and stored at a predetermined temperature.

[0086] As described above, the shea butter-based preservative-free cosmetic composition according to the present invention utilizes shea butter obtained through the above-described process. This shea butter does not use any chemical solvents, thereby preventing stability issues regarding residual solvents and environmental pollution, and contains shea butter having effective ingredients.

[0087] The shea butter-based preservative-free cosmetic comprising the shea butter-based preservative-free cosmetic composition according to the present invention described above is preferably a cosmetic in the form of a balm, but is not limited thereto.

[0088] Meanwhile, the inventor of the present invention commissioned the testing institution Global Standard Certification Institute Co., Ltd. to conduct a 'human application test for primary skin irritation evaluation' regarding a cosmetic product (balm formulation) containing the shea butter-based preservative-free cosmetic composition according to the present invention.

[0089] FIG. 7 is a table showing all ingredients used in the human application test (attached to the results report), and FIG. 8 to 15 are drawings excerpted from the results report of the human application test.

[0090] As a result of commissioning a ‘human application test for primary skin irritation evaluation’ to Global Standard Certification Institute, Inc., as shown in FIGS. 7 to 15, it was confirmed that the cosmetic product (balm formulation) containing the shea butter-based preservative-free cosmetic composition according to the present invention has a primary skin irritation index of 0.00 and falls within the non-irritating range.

[0091] According to the shea butter-based preservative-free cosmetic composition and the shea butter-based preservative-free cosmetic containing the same according to the present invention as described above, it is possible to provide a functional cosmetic (cosmetic) containing shea butter with effective ingredients as a main composition without using any chemical solvents to prevent stability issues regarding residual solvents and environmental pollution. In particular, there is an advantage of being able to provide a natural highly moisturizing cosmetic that does not require preservatives because it does not contain purified water.

[0092] In addition, the present invention has the advantage of providing a functional cosmetic that can be used on various parts of the body, such as the face, body, hands, and hair, as a mild and gentle ingredient by containing shea butter as a main ingredient, and can provide intensive care for rough areas (elbows, knees, etc.) and cracked skin, and can provide deep hydration to the skin by being rich in unsaturated fatty acids (oleic acid and stearic acid), and can prevent moisture loss and maintain moist skin by forming a protective barrier on the skin surface, and can nourish the skin by containing natural vitamins such as vitamins A, E, and F.

[0093] In addition, the present invention has the advantage of providing a functional cosmetic that promotes skin regeneration and recovery, soothes and protects the skin, has anti-inflammatory and skin-soothing effects to help soothe sensitive or irritated skin, protects the skin from harmful external environments, minimizes damage caused by irritation, strengthens the skin barrier to maintain a healthy skin condition, promotes ceramide production to improve skin firmness and moisture retention, and is rich in antioxidant components to protect the skin from free radicals and contribute to reducing signs of aging.
