Description

Technology Field

[0001] The present invention relates to a deodorant composition with improved fragrance power and a method for manufacturing the same. Background Technology

[0003] With the recent spread of the well-being trend, there is a growing demand for products that go beyond simply eliminating odors to maintain a pleasant scent for a long time while being harmless to the human body.

[0004] In particular, unpleasant odors from daily life in enclosed spaces such as homes, offices, and vehicles can cause headaches or discomfort and can also be a cause of emotional instability.

[0005] Accordingly, various types of deodorizers and air fresheners have been developed to effectively remove odors and simultaneously create a pleasant environment.

[0006] Spray-type air fresheners, which were primarily used in the early days, had the advantage of producing an immediate deodorizing effect, but most relied on an odor masking method that simply covered up bad odors with fragrances.

[0007] As a result, since the odor-causing substances were not fundamentally removed, the fragrance quickly faded, and the foul odor frequently returned over time.

[0008] Furthermore, safety concerns have been continuously raised that fine synthetic chemicals sprayed into the air could cause respiratory diseases or be harmful to the human body.

[0009] To address these issues, liquid and gel-type solid air fresheners have emerged.

[0010] Among these, gel-type solid compositions mainly use synthetic polymer gelling agents and artificial deodorizing / fragrance ingredients, so it was difficult to provide complete confidence in terms of safety.

[0011] In addition, due to limitations in the manufacturing process, the active ingredients inside the gel were not evenly dispersed and clumped together locally, resulting in problems such as uneven fragrance intensity or a rapid decline in efficacy over time.

[0012] In particular, despite active research being conducted on eco-friendly products utilizing plant-derived ingredients, there were many cases where the inherent deodorizing and fragrance efficacy of the extracts could not be fully realized due to the instability of plant extracts and limitations in the manufacturing process.

[0013] For example, many of the active ingredients contained in plant extracts are sensitive to heat, so they were prone to denaturation or destruction during typical high-temperature extraction. In addition, simply mixing the ingredients made it difficult to stably capture the fragrance active ingredients within the gel, making it difficult to expect a strong and sustained fragrance effect. The problem to be solved

[0015] The inventors recognized the problems of the prior art and confirmed that a deodorant composition manufactured using a specific manufacturing method can possess excellent fragrance power (consistency and persistence), thereby completing the present invention.

[0016] The present invention is,

[0019] s2) a step of cooling the gellan gum solution to 45°C, and then slowly adding the component mixture while stirring to form an emulsion; and

[0020] s3) A step of curing the above emulsion at room temperature so that it solidifies.

[0021] The present invention relates to a deodorant composition with enhanced fragrance diffusion, wherein the fragrance component is one or more selected from phytoncide-based essential oils extracted from cypress, pine, or fir; herbal-based essential oils extracted from lavender, eucalyptus, or rosemary; or citrus-based essential oils extracted from lemon, orange, or grapefruit.

[0022] The present invention relates to a deodorant composition with enhanced fragrance, wherein the fragrance component is a phytoncide-based essential oil extracted from cypress, pine, or fir trees.

[0023] The present invention relates to a deodorizing composition with improved fragrance power, wherein the deodorizing components are wheat germ extract, malt extract, soybean extract, and glycine.

[0024] The present invention relates to a deodorant composition with improved fragrance power, wherein the solvent is a mixed solvent of ethanol and purified water.

[0025] The present invention relates to a deodorant composition with enhanced fragrance, wherein the wheat germ extract is prepared by a method comprising the following steps:

[0026] a1) Step of grinding wheat germ;

[0027] a2) A step of obtaining an extract by immersing the ground wheat germ in a 20-30% (w / w) aqueous ethanol solution at 30-40℃ for 12-24 hours;

[0028] a3) A step of removing impurities by centrifuging the above extract at 2,000 to 3,000 rpm;

[0029] a4) A step of filtering the centrifuged extract through a ceramic filter with a pore size of 0.2 to 1 μm; and

[0030] a5) A step of concentrating the above-mentioned filtered extract under reduced pressure.

[0031] The present invention relates to a method for manufacturing a deodorant composition with improved fragrance power. means of solving the problem

[0033] The following describes this in detail. All combinations of the various elements disclosed in this invention fall within the scope of this invention. Furthermore, the scope of this invention should not be considered limited by the following detailed description.

[0034] Furthermore, unless otherwise defined in this specification, all terms used herein should be understood to have the same meaning as generally understood by those skilled in the art to which the present invention pertains.

[0035] In addition, singular expressions include plural expressions unless they are interpreted as being distinct from the context.

[0036] In this specification, terms such as "first," "second," etc., may be used to distinguish or describe one component from another, but the components should not be interpreted restrictively by said terms. For example, within the scope of the present invention, a first component may be named as a second component or vice versa.

[0037] Additionally, “degrees” combined with numbers in this specification represents degrees Celsius (°C) and may be used interchangeably with “°C” (for example, “100 degrees” is used with the same meaning as “100°C”).

[0039] The present invention

[0040] A deodorant composition with enhanced fragrance power comprising the following steps is provided:

[0041] s1) A step of preparing a component mixture by mixing fragrance components and deodorizing components in a solvent, and preparing a gellan gum solution by dissolving gellan gum in purified water at 70°C;

[0042] s2) a step of cooling the gellan gum solution to 45°C, and then slowly adding the component mixture while stirring to form an emulsion; and

[0043] s3) A step of curing the above emulsion at room temperature so that it solidifies.

[0044] In the present invention, the s1 step is a step of separately preparing the fragrance component and the deodorizing component, which are the core active ingredients of the composition, and the gellan gum solution constituting the gel matrix.

[0045] In the present invention, the s1 step comprises two processes of preparing a component mixture and preparing a gellan gum solution, each performed separately regardless of the order.

[0046] When the above deodorizing and fragrance components are mixed directly with gellan gum, they may not be evenly dispersed within the final composition due to issues of miscibility between the components or non-uniformity of the gelation reaction.

[0047] Therefore, at this stage, fragrance components and deodorizing components are mixed separately in a solvent to prepare a uniform and stable mixture of components, and when mixed with the gellan gum solution, the components are uniformly captured inside the gel.

[0048] In addition, gellan gum has the characteristic of dissolving at a specific temperature to form a gel. By dissolving gellan gum in hot water at 70°C, the gellan gum molecules can be sufficiently dispersed and hydrated to form a uniform and viscous solution.

[0049] In the present invention, gellan gum is a natural polysaccharide gelling agent used to form the composition into a solid gel type.

[0050] The gellan gum mentioned above is a type of water-soluble dietary fiber obtained through microbial fermentation, and provides excellent gelling ability and transparency even in small amounts. By stably capturing moisture and deodorizing components within the composition in a three-dimensional network structure, it controls the evaporation rate and allows the deodorizing components to be released consistently.

[0051] If the content of the gellan gum is less than 5% by weight, the strength of the gel may be weakened, making the formulation unstable, and if it exceeds 15% by weight, the gel may become excessively hard, which may hinder the release of deodorizing ingredients or make stirring during the manufacturing process difficult.

[0052] In the preparation of the above gellan gum solution, if the temperature is below 60°C, the gellan gum is not sufficiently dissolved, so lumps may form inside the gel or the gel strength may be weakened, making the final formulation unstable; conversely, if the temperature exceeds 80°C, the gelling ability may be reduced due to excessive thermal decomposition of the gellan gum molecules, which is undesirable.

[0053] In the above s1 step, the fragrance component may be one or more selected from phytoncide-based essential oils extracted from cypress, pine, or fir; herbal-based essential oils extracted from lavender, eucalyptus, or rosemary; or citrus-based essential oils extracted from lemon, orange, or grapefruit, but is not limited thereto.

[0054] According to an embodiment of the present invention, the fragrance component may be a phytoncide-based essential oil extracted from cypress, pine, or fir trees, but is not limited thereto.

[0055] According to an embodiment of the present invention, the deodorizing component may be wheat germ extract, malt extract, soybean extract, and glycine, but is not limited thereto.

[0056] The wheat germ extract used in the present invention is an extract obtained by isolating only the germ from the seeds of wheat (Triticum aestivum).

[0057] The above wheat germ is a part that accounts for about 2-3% of the total weight of the wheat kernel and contains concentrated nutrients necessary for the germination of wheat. In particular, it contains abundant protein, essential fatty acids, vitamin E, B vitamins (B1, B2, B6), phenolic acid compounds such as ferulic acid, and flavonoid compounds.

[0058] In the present invention, the wheat germ extract can be purchased from a specialized retailer or manufactured directly for use.

[0059] In the present invention, "extract" refers to a product obtained by extraction using a suitable extraction solvent, and said extract includes the extract itself and all formulations of extracts that can be formed using the extract, such as an extract obtained by extraction, a diluted or concentrated extract, a dried product obtained by drying the extract, a modified or purified product thereof, a fraction thereof, or a mixture thereof.

[0060] The extract of the present invention may be prepared and used in the form of a dried powder after extraction, but is not limited thereto.

[0061] In the present invention, the extract may be prepared using extraction methods commonly used in the art. For example, methods such as hot water extraction, hot water extraction, cold maceration extraction, reflux cooling extraction, ultrasonic extraction, and high-temperature pressurized extraction may be used.

[0062] In preparing the extract of the present invention, the extraction solvent may be water; lower alcohols having 1 to 4 carbon atoms, such as methanol, ethanol, propyl alcohol, butyl alcohol; polyalcohols, such as glycerin, butylene glycol, propylene glycol; hydrocarbon solvents, such as chloroform, methyl acetate, ethyl acetate, benzene, hexane, diethyl ether, petroleum ether, dichloromethane; or a mixture thereof, but is not limited thereto.

[0063] According to an embodiment of the present invention, the wheat germ extract as a deodorizing component may be prepared by a method comprising the following steps:

[0064] a1) Step of grinding wheat germ;

[0065] a2) A step of obtaining an extract by immersing the ground wheat germ in a 20-30% (w / w) aqueous ethanol solution at 30-40℃ for 12-24 hours;

[0066] a3) A step of removing impurities by centrifuging the above extract at 2,000 to 3,000 rpm;

[0067] a4) A step of filtering the centrifuged extract through a ceramic filter with a pore size of 0.2 to 1 μm; and

[0068] a5) A step of concentrating the above-mentioned filtered extract under reduced pressure.

[0069] In the present invention, the above step a1 is a step for maximizing the efficiency of the next step, the extraction process, by increasing the surface area of ​​the wheat germ.

[0070] When wheat germ is ground to finely sized particles through the above step a1, the surface area in contact with the solvent is significantly increased. This facilitates the extraction solvent's easy access to deodorizing active substances (e.g., ferulic acid, flavonoids, etc.) present within the wheat germ, thereby shortening the extraction time and increasing the extraction yield.

[0071] The above grinding method may use a roller mill, a hammer mill, or an ultrafine grinder.

[0072] According to an embodiment of the present invention, it may be preferable to adjust the size of the ground particles to within 1 to 2 mm in consideration of extraction efficiency, but is not limited thereto.

[0073] In the present invention, step a2 is a step of selectively extracting a deodorizing active ingredient from crushed wheat germ.

[0074] By immersing the wheat germ ground through the above step a2 in a low-concentration aqueous ethanol solution of 20–30% (w / w) at a low temperature of 30–40°C for 12–24 hours, an extract with excellent efficacy that is difficult to obtain with conventional high-temperature extraction methods is prepared.

[0075] Deodorizing active substances contained in wheat germ, such as ferulic acid and flavonoids, are susceptible to heat, so there is a high risk that the components will be denatured or destroyed during high-temperature extraction. Therefore, the present invention limits the extraction temperature to a low temperature of 30 to 40°C to minimize the destruction of active ingredients, while simultaneously suppressing the extraction of unnecessary proteins or lipids to maximize the efficacy of the extract. If the extraction temperature is below 30°C, the extraction efficiency of the active ingredients is significantly reduced, making it difficult to expect a sufficient deodorizing effect; if it exceeds 40°C, the risk of the active ingredients being denatured or destroyed by heat increases, which is undesirable.

[0076] In addition, by using an aqueous ethanol solution of 20~30% (w / w), fat-soluble components that are difficult to extract with water alone are dissolved, and the extraction of polar components is prevented by an ethanol concentration that is too high, thereby efficiently extracting only the active ingredients related to deodorization.

[0077] If the above ethanol concentration is less than 20%, the extraction efficiency of fat-soluble active ingredients may decrease, and if it exceeds 30%, unnecessary ingredients may be excessively extracted, which may impair the purity and stability of the composition.

[0078] In addition, the soaking time is set to 12 to 24 hours to ensure that the active ingredients are sufficiently extracted, while preventing spoilage caused by unnecessary ingredients or the proliferation of microorganisms.

[0079] If the above immersion time is less than 12 hours, the active ingredient may not be sufficiently extracted, and if it exceeds 24 hours, stability problems such as discoloration of the extract or microbial growth may occur, which is undesirable.

[0080] In the present invention, step a3 is a step that effectively removes solid impurities contained in the extract to increase the purity and stability of the extract.

[0081] The extract obtained by immersing the above-mentioned crushed wheat germ in an aqueous ethanol solution may contain insoluble solid impurities, such as fine wheat germ residue, proteins, and lipids, in addition to the deodorizing active ingredient. These impurities may cause turbidity in the final product, thereby degrading its aesthetic quality, and may form precipitates during long-term storage, potentially leading to stability issues.

[0082] Therefore, the present invention effectively separates fine impurities and precipitates floating inside the extract by performing centrifugation at a speed of 2,000 to 3,000 rpm.

[0083] If the above centrifugal separation speed is less than 2,000 rpm, the separation of impurities is not sufficiently performed, and the turbidity of the extract may increase; if it exceeds 3,000 rpm, energy efficiency decreases and the process time becomes longer, making it uneconomical.

[0084] In the present invention, step a4 is a step of filtering the centrifuged extract through a ceramic filter with a pore size of 0.2 to 1 μm to maximize the purity of the extract and remove microorganisms.

[0085] Conventional deodorizer manufacturing processes primarily used paper or non-woven filters. However, these filters have uneven pores, making it difficult to completely remove fine impurities and microorganisms, and clogging frequently occurred during the filtration process.

[0086] To solve these problems, the present invention uses a ceramic filter with a specific pore size (0.2 to 1 μm).

[0087] The ceramic filter described above has a uniform and fine pore structure, so it effectively filters out fine impurities remaining in the extract, thereby increasing the transparency of the extract.

[0088] In addition, considering that the size of microorganisms (e.g., bacteria) is generally 1 μm or larger, this pore size is very effective in physically blocking microorganisms and maintaining the sterile state of the extract.

[0089] If the pore size of the ceramic filter is less than 0.2 μm, the filtration speed is significantly slowed down, which lowers the efficiency of the entire process, and if it exceeds 1 μm, the removal effect of fine impurities and microorganisms is negligible and is undesirable.

[0090] In the present invention, step a5 is a step of concentrating the filtered extract under reduced pressure to remove moisture and increase the content of the active ingredient.

[0091] The extract obtained after step a4 still contains a high proportion of water and ethanol. If the extract in this state is used as is in the final composition, the concentration of the deodorizing active substance is low, resulting in minimal effect, and the ethanol component volatilizes, which can impair the stability of the gel.

[0092] Therefore, the present invention effectively removes moisture and ethanol at low temperatures by lowering the boiling point of the extract through a reduced-pressure concentration process.

[0093] The above vacuum concentration process has the advantage of preventing heat-sensitive deodorizing active ingredients from being destroyed by exposure to high temperatures, while still being able to increase the concentration of the extract to a desired level.

[0094] The malt extract used in the present invention is an extract obtained by grinding and purifying malt obtained by germinating a grain such as barley (Hordeum vulgare).

[0095] The above malt is rich in various enzymes and amino acids produced during the germination process of grains. In particular, enzymes such as amylase and peptide components present in malt have excellent ability to decompose or adsorb specific odor molecules, and these components assist in the chemical neutralization action of wheat germ extract, thereby inducing an increase in deodorizing effect.

[0096] In the present invention, the malt extract can be purchased from a specialized retailer or manufactured directly for use.

[0097] The soybean extract used in the present invention is an extract obtained from the seeds of the soybean (Glycine max).

[0098] The aforementioned soybeans are rich in various bioactive substances, such as saponins and isoflavones, in addition to protein, carbohydrates, and fats. These components possess excellent antibacterial and antioxidant effects, inhibit the growth of odor-causing bacteria, and assist in deodorization. Furthermore, they enhance deodorizing power by adsorbing specific odor molecules and contribute to increasing the longevity of the composition's effects.

[0099] In the present invention, the soybean extract can be purchased from a specialized retailer or manufactured directly for use.

[0100] In the present invention, glycine is an amino acid with the simplest structure and serves as a deodorizing component that effectively neutralizes odor molecules.

[0101] The glycine mentioned above has both an amine group (-NH2) and a carboxyl group (-COOH) within its molecule, and thus exerts a neutralizing effect against both acidic odors (e.g., sweat, vinegar) and basic odors (e.g., ammonia). This amphoteric characteristic provides a wider range of deodorizing effects than general deodorizing ingredients that react only to specific odors, and can create a synergistic effect by complementing the deodorizing effects of wheat germ, malt, and soybean extracts.

[0102] In the present invention, the glycine can be purchased and used from a specialized retailer.

[0103] According to an embodiment of the present invention, wheat germ extract, malt extract, soybean extract, and glycine as deodorizing ingredients may be mixed in a weight ratio of 10-1:3-1:3-1:3-1, preferably in a weight ratio of 10:3:3:3, but are not limited thereto.

[0104] According to an embodiment of the present invention, the solvent may be a mixed solvent of ethanol and purified water, but is not limited thereto.

[0105] In addition, when the above solvent is a mixed solvent of ethanol and purified water, the ethanol and purified water may be mixed in a volume ratio of 1:1, but are not limited thereto.

[0106] In the present invention, the s2 step is a process of combining a gelling agent and a deodorizing component to form a continuous-release solid emulsion.

[0107] Temperature control and stepwise mixing are important in the above s2 step.

[0108] If the temperature is below 40℃, the gellan gum hardens too quickly, so the deodorizing components are not evenly dispersed within the gel, and if it exceeds 50℃, the viscosity of the gellan gum solution decreases, and there is a risk that the deodorizing component mixture will separate.

[0109] In addition, when the deodorizing ingredient mixture is slowly added while stirring, deodorizing active ingredients such as wheat germ extract are finely and uniformly captured within the three-dimensional network structure of gellan gum.

[0110] According to an embodiment of the present invention, the gradual addition may mean adding a deodorizing component mixture at a rate of 15 mL per minute, but is not limited thereto.

[0111] If the above addition speed is too fast, gelation may occur unevenly or the deodorizing ingredients may clump together in one place, resulting in inconsistent deodorizing effects on the final product.

[0112] Step s3 of the present invention is to solidify the emulsion formed in s2 to complete the final deodorant composition.

[0113] The above s3 step is a process in which the emulsion gels and changes into a hard solid form, which is carried out at room temperature without a separate heat treatment or cooling process.

[0114] The above curing time may vary depending on the mixing ratio of the composition or the ambient temperature, but it usually hardens into a sufficiently solid form within 10 to 24 hours. Through this process, the liquid emulsion is transformed into a solid fragrance of the desired form, and the fragrance components are stably maintained within the gel, thereby achieving the effect of continuously exhibiting fragrance power.

[0116] Another aspect of the present invention provides a method for preparing a deodorant composition with improved fragrance power, comprising the following steps:

[0117] s1) A step of preparing a component mixture by mixing fragrance components and deodorizing components in a solvent, and preparing a gellan gum solution by dissolving gellan gum in purified water at 70°C;

[0118] s2) a step of cooling the gellan gum solution to 45°C, and then slowly adding the component mixture while stirring to form an emulsion; and

[0119] s3) A step of curing the above emulsion at room temperature so that it solidifies.

[0120] The above fragrance components may be one or more selected from phytoncide-based essential oils extracted from cypress, pine, or fir; herbal-based essential oils extracted from lavender, eucalyptus, or rosemary; or citrus-based essential oils extracted from lemon, orange, or grapefruit, but are not limited thereto.

[0121] According to an embodiment of the present invention, the fragrance component may be a phytoncide-based essential oil extracted from cypress, pine, or fir trees, but is not limited thereto.

[0122] According to an embodiment of the present invention, the deodorizing component may be wheat germ extract, malt extract, soybean extract, and glycine, but is not limited thereto.

[0123] According to an embodiment of the present invention, the solvent may be a mixed solvent of ethanol and purified water, but is not limited thereto.

[0124] According to an embodiment of the present invention, the wheat germ extract may be prepared by a method comprising the following steps:

[0125] a1) Step of grinding wheat germ;

[0126] a2) A step of obtaining an extract by immersing the ground wheat germ in a 20-30% (w / w) aqueous ethanol solution at 30-40℃ for 12-24 hours;

[0127] a3) A step of removing impurities by centrifuging the above extract at 2,000 to 3,000 rpm;

[0128] a4) A step of filtering the centrifuged extract through a ceramic filter with a pore size of 0.2 to 1 μm; and

[0129] a5) A step of concentrating the above-mentioned filtered extract under reduced pressure.

[0130] In the present invention, the specific details of the manufacturing method are substantially the same as those described in the composition, unless otherwise stated, and are omitted to avoid repetition. Effects of the invention

[0132] The deodorant composition according to the present invention prevents the fragrance from volatilizing rapidly and allows it to be emitted continuously, thereby providing excellent fragrance longevity and increasing user satisfaction.

[0133] In addition, the deodorizing composition according to the present invention has a deodorizing component uniformly dispersed within a gellan gum matrix, so that the odor removal effect can be consistently maintained.

[0134] In addition, the deodorant composition according to the present invention is manufactured in the form of a solid gel, making it very convenient to use as there is no spillage or leakage from the container, and it is safer for the human body as it does not use excessive volatile organic compounds (VOCs).

[0135] In addition, the deodorant composition according to the present invention does not easily collapse in shape even at high temperatures, so the shape of the product can be stably maintained even in high-temperature environments such as summer, thereby allowing the quality of the product to be maintained for a long period.

[0136] The effects obtainable from the embodiments are not limited to those mentioned above, and other unmentioned effects can be clearly derived and understood by a person skilled in the art based on the detailed description below. Specific details for implementing the invention

[0138] The present invention will be described in more detail below by way of examples. However, these examples are intended to illustrate the invention and the scope of the invention is not limited by these examples. Furthermore, each component or feature may be considered optional unless otherwise explicitly stated. Each component or feature may be implemented in a form not combined with other components or features. Additionally, various embodiments may be constructed by combining some components and / or features. Some components or features of one embodiment may be included in another embodiment or replaced with corresponding components or features of another embodiment. Furthermore, terms not specifically defined in this specification should be understood to have the meaning commonly used in the technical field to which the present invention belongs.

[0140] Preparation Example 1

[0141] Wheat germ is ground to a size of 1 to 2 mm using a roller mill.

[0142] The crushed wheat germ is immersed in a 20-30% (w / w) ethanol aqueous solution maintained at 30-40°C for 12-24 hours to obtain an extract.

[0143] The above extract is centrifuged at a speed of 2,000 to 3,000 rpm to separate fine wheat germ residue and insoluble proteins.

[0144] The centrifuged extract is filtered through a ceramic filter with a pore size of 0.2 to 1 μm.

[0145] After concentrating the filtrate under reduced pressure to effectively remove moisture and ethanol at a low temperature, a wheat germ extract of the desired concentration is obtained.

[0147] Preparation Example 2

[0148] Grind 500g of malt and 500g of soybeans separately.

[0149] Crushed malt and beans are each placed in 5L of purified water at 80℃ and hot water extracted for 2 hours.

[0150] The extract is filtered and concentrated under reduced pressure to obtain 100g of malt extract and 100g of soybean extract.

[0152] Examples

[0153] The above-prepared deodorizing ingredients (10g wheat germ extract, 3g malt extract, 3g soybean extract), 3g glycine, and fragrance ingredients (5g phytoncide essential oil) were added to a solvent (purified water:ethanol = 1:1, volume ratio) and stirred at 300 rpm for 10 minutes to prepare a uniform mixture of ingredients.

[0154] In addition, 8g of gellan gum was added to 97g of purified water at 70℃ and stirred sufficiently at 500 rpm for 20 minutes to prepare a gellan gum solution.

[0155] After cooling the gellan gum solution to 45°C, the above component mixture was slowly added (15 mL per minute) using a stirrer (400 rpm) to form a uniform emulsion.

[0156] The formed emulsion was placed in a cup and cured at room temperature (25℃) for 12 hours to complete a transparent and hard gel-type deodorant composition.

[0158] Experimental Example 1: Evaluation of Scent Durability

[0159] The experimental group and the control group were placed in the same area (20m²) 2 After placing each in a sealed space, three expert panelists evaluated the intensity of the scent once a day on a 5-point scale (5: very strong, 1: weak, 0: no scent) and measured the time until the scent was no longer perceived (evaluation score less than 1 point), and the evaluation results are shown in Table 1.

[0160] division Scent duration Examples 30 days Comparison group 1 15th Comparison group 2 3 days

[0161] (Comparison Group 1: Standard gel-type deodorizer, Comparison Group 2: Standard liquid spray)

[0163] The composition of the present invention showed a fragrance duration approximately twice as long as that of Comparative Group 1 (general gel type) and approximately 10 times longer than that of Comparative Group 2 (liquid spray type).

[0164] This means that gellan gum stably captures fragrance components in a three-dimensional network structure, thereby suppressing rapid volatilization and ensuring that the fragrance effect lasts for a long time.

[0166] Experimental Example 2: Evaluation of Deodorizing Effect (Ammonia Gas)

[0167] Sealed acrylic box (1m 3 Ammonia gas was injected into ) to set the initial concentration to 50 ppm.

[0168] After placing the experimental group and the control group into the box, the residual ammonia concentration at 1 hour was measured using a gas detector (GA-1000, Riken Keiki).

[0169] The deodorization rate was calculated according to the following formula.

[0170] [Formula 1]

[0171] Deodorization Rate (%) = ((Initial Ammonia Concentration - Final Ammonia Concentration) / Initial Ammonia Concentration) x 100

[0172] division Initial concentration (ppm) Final concentration (ppm) Deodorization rate (%) Examples 50 3.5 93 Comparison group 1 50 15.0 70 Comparison group 2 50 20.0 60

[0173] The composition of the present invention exhibited a significantly superior deodorizing effect compared to comparison groups 1 and 2.

[0174] This is because wheat germ, malt, and soybean extracts work together to effectively neutralize and adsorb odor molecules, and it is proven that deodorizing components are uniformly dispersed within the gel matrix, continuously exhibiting a consistent deodorizing effect.

[0176] The various embodiments described above may be embodied in other specific forms without departing from the technical idea and essential features. Accordingly, the above detailed description should not be interpreted restrictively in all respects but should be considered exemplary. The scope of the various embodiments shall be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the various embodiments are included within the scope of the various embodiments.
