Description

Technical Field

[0001] This invention belongs to the field of plant essential oil technology, and particularly relates to a herbal aromatic mixture and its preparation method. Background Technology

[0002] In traditional medicine, mugwort, as a traditional medicinal plant, has been used for fumigation and disinfection since ancient times. The folk custom of "using mugwort smoke to ward off epidemics" reflects its practical value in disinfecting livestock and poultry pens. Its mechanism of action mainly involves producing smoke through burning mugwort, which has an insect-repelling or bactericidal effect. However, the burning process of mugwort has certain safety hazards, and the produced smoke also contains harmful components. With the development of modern technology, methods such as fumigation and soaking have gradually emerged to process mugwort. As an important branch of natural health products, compound essential oils have shown a rapid growth trend in the global market in recent years. With the increasing demand of consumers for physical and mental healing, compound essential oils have expanded their application scenarios through the synergistic effect of multiple components and are widely used in fields such as beauty and skin care, stress relief, and sleep improvement. Modern research has gradually verified some of its efficacy, such as antibacterial and anti-inflammatory properties, while advancements in essential oil blending technology have driven product innovation. The current market has formed a pattern where professional aromatherapy brands and mass-market fast-moving consumer goods coexist, and e-commerce channels have accelerated the popularization of consumption.

[0003] Chinese patent document CN114028465A discloses a type of mugwort essential oil with antibacterial, anti-mite, and anti-inflammatory effects, and its preparation method. The oil comprises, by weight, 3-5 parts mugwort essential oil, 8-15 parts alcohol, 0.5-1 part tea tree essential oil, 0.4-0.8 parts eucalyptus essential oil, and 0.5-0.9 parts lemon essential oil. The volatile oil components in mugwort, such as camphor, bornyl acetate, and caryophyllene, possess excellent antibacterial and anti-inflammatory properties. Adding mugwort essential oil to alcohol further enhances its antibacterial and anti-inflammatory effects through the disinfecting properties of alcohol. Simultaneously, the bactericidal and insecticidal effects of tea tree oil, eucalyptus oil, and lemon essential oil effectively remove mites and are harmless to humans.

[0004] In practical applications, the active ingredients in essential oils diffuse into the air to disinfect and sterilize. However, if the concentration of these active ingredients in the air is too low, they cannot effectively inhibit or kill bacteria. The key indicator determining the concentration of active ingredients in the air is the diffusion rate of the essential oil. The patented solution mentioned above mixes various essential oils with highly volatile alcohol, utilizing its high diffusion rate to rapidly increase the concentration of active ingredients in the environment. While this achieves a good disinfection and sterilization effect, its persistence is poor, and the high volatility also causes the active ingredients to dissipate quickly. Furthermore, the amount of essential oil used is also relatively high, resulting in significant waste. Summary of the Invention

[0005] To overcome the technical problems of existing technologies where increasing the diffusion rate of essential oils helps with disinfection and sterilization, but the accelerated diffusion rate also increases the dissipation rate, resulting in poor retention and requiring a large amount of essential oil, this invention aims to provide a herbal aromatic mixture and its preparation method. An aromatic masterbatch composed of five dried herbs—borneol camphor leaves, artemisia leaves, agastache, patchouli, and lavender—is mixed with a blend of essential oils consisting of borneol camphor oil, aromatic camphor oil, litsea cubeba oil, and peppermint oil. Through a permeation soaking process, significant improvements in homologous transformation and adsorption rate are achieved. The aromatic masterbatch acts as a reservoir in this process, promoting the synthesis of aromatic hydrocarbons from similar oils. The aromatic masterbatch itself contains aromatic hydrocarbon components (i.e., raw oils). Through the combined soaking of liquid and dry materials, a mixture with different aromas is formed, releasing sufficient and slow odors with richer aroma layers.

[0006] To achieve the above objectives, the present invention employs the following technical solution: a herbal aromatic mixture comprising a compound essential oil and an aromatic masterbatch soaked in the compound essential oil; the compound essential oil is composed of camphor oil, aromatic camphor oil, litsea cubeba oil, and peppermint oil; the aromatic masterbatch is composed of mugwort, camphor leaves, agastache rugosa, lavender, and patchouli mixed and kneaded into irregular flakes.

[0007] Furthermore, the camphor oil accounts for 20% to 70% of the total mass of the compound essential oil; the aromatic camphor oil accounts for 5% to 60% of the total mass of the compound essential oil; the litsea cubeba oil accounts for 1% to 15% of the total mass of the compound essential oil; and the peppermint oil accounts for 0.5% to 20% of the total mass of the compound essential oil.

[0008] Specifically, the purity of the camphor oil, the aromatic camphor oil, the litsea cubeba oil, and the peppermint oil is greater than or equal to 90%.

[0009] Further, the aromatic masterbatch is mixed in the following proportions by weight: 20 to 30 parts of Artemisia argyi, 25 to 35 parts of Camphor tree leaves, 10 to 20 parts of Eupatorium fortunei, 10 to 20 parts of Lavender, and 20 to 30 parts of Patchouli.

[0010] Specifically, the moisture content of the mugwort, camphor leaves, agastache, lavender, and patchouli is less than or equal to 15%.

[0011] Furthermore, the mass ratio of the aromatic masterbatch to the compound essential oil is 5:2-3.

[0012] A method for preparing a herbal aromatic mixture, used in the herbal aromatic mixture, includes the following steps:

[0013] Step 1: Mix 20 to 30 parts by weight of Artemisia argyi, 25 to 35 parts by weight of Cinnamomum camphora, 10 to 20 parts by weight of Eupatorium fortunei, 10 to 20 parts by weight of Lavender, and 20 to 30 parts by weight of Patchouli to obtain aromatic masterbatch.

[0014] Step 2: Knead the aromatic masterbatch into irregular flakes, then pour it into a storage container and gently press and spread it out.

[0015] Step 3: Mix camphor oil (20%-70% by weight), aromatic camphor oil (5%-60%), litsea cubeba oil (1%-15%), and peppermint oil (0.5%-20%) to form a compound essential oil.

[0016] Step 4: Pour the compound essential oil into the storage container according to the mass ratio of aromatic masterbatch to compound essential oil of 5:2-3; control the amount of aromatic masterbatch and compound essential oil so that they can just fill the storage container.

[0017] Step 5: Using the static capping soaking method, the herbal aromatic mixture is obtained by soaking for 2-5 days through the reaction of the double-combination permeation soaking and the mother-child coupling.

[0018] Furthermore, the mugwort, camphor leaves, agastache, lavender, and patchouli are each extracted by temperatureless distillation to reduce the moisture content to below 15%, and the extracted oil is used in the composition of the compound essential oil in step three.

[0019] Furthermore, in step two, the particle size of the aromatic masterbatch in the storage container gradually decreases from top to bottom; wherein, the upper layer of the aromatic masterbatch in the storage container is Artemisia argyi, and the lower layer is small particles of 20-40 mesh.

[0020] The large size of the upper layer of aromatic masterbatch produces a slow chemical effect, while the lower layer of small-particle masterbatch (20 to 40 mesh) has strong adsorption and releases aromatic hydrocarbons rapidly. The large particle size of the upper layer originates from the kneading and rolling of Artemisia argyi into granules, which completes the sealing and storage. The lower layer of small-particle masterbatch releases aromatic hydrocarbons, which are absorbed and converted by Artemisia argyi, resulting in a static adsorption and storage effect. Then, when the lid is opened, the aromatic hydrocarbons are released into the environment, exhibiting antiviral and bactericidal effects. A biochemical reaction between macromolecules and small molecules occurs, with the upper layer sealing the large-sized Artemisia argyi, and the lower layer releasing aromatic hydrocarbons for the upper large-sized Artemisia argyi to slowly absorb. Through the slow sealing effect of the upper layer of Artemisia argyi, the rapidly volatile aromatic hydrocarbons in the lower layer are stored in a homologous solution within the large-sized Artemisia argyi. When the lid is opened, the aromatic waves are released through the slow volatilization of the upper layer of Artemisia argyi.

[0021] Preferably, the storage device is made of ceramic or glass; the storage device has a double-layer structure that is larger at the top and smaller at the bottom.

[0022] The storage device is designed with a larger top and smaller bottom using a reasonable physical method. The two layers complement each other to ensure the long-term quality of aromatic hydrocarbons.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention employs a combination of biological natural methods and physical release mechanisms. By kneading aromatic masterbatch into flake-like form, and filling the storage container with the highly breathable aromatic masterbatch, it is then soaked in a four-in-one compound essential oil. This process allows for the permeation and homologous fermentation of the aromatic masterbatch, achieving slow and continuous evaporation during storage and thus maintaining the persistence of the aroma. The five-flavor masterbatch itself contains aromatic hydrocarbon components (i.e., raw oils). Through the compound soaking of liquid and dry materials, a mixture with different aromas is formed, resulting in a more layered aroma diffusion and providing a pleasant olfactory experience.

[0025] 2. Extended shelf life / usage period: To address the issues of easy leakage, rapid evaporation, and short protection period of essential oils, the compound essential oil and aromatic masterbatch are mixed and soaked. The dried herbal masterbatch acts as a storage container in this process, promoting the synthesis of aromatic hydrocarbons of the same type of oil, achieving homologous transformation and significantly improving the adsorption rate, thus significantly improving the storage rate and volatilization cycle of aromatic substances.

[0026] 3. Enhanced therapeutic effects of aromatic masterbatch and blended essential oils: Compared with previous studies that used essential oil blending to achieve synergistic aromatic effects, this patent innovatively proposes a process of impregnating herbal masterbatch with compound essential oils. Through molecular penetration, it significantly enhances the synergistic effect of plant volatiles, improves the efficacy of plant essence oil extracts, and significantly enhances the therapeutic effects of aromatic hydrocarbons.

[0027] 4. The herbal aromatic mixture of the present invention not only has the original functions of purifying the constituent raw materials, refreshing the mind, repelling insects and sterilizing, but can also directly inactivate viruses, increasing the application scenarios and target species. The disinfection and sterilization effects and efficiency are also significantly improved, and the air purification effect is better. This formula does not contain alcohols or other highly volatile and flammable components, so it has better flame retardancy and higher safety. Detailed Implementation

[0028] The present invention will now be further described in conjunction with specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] A herbal aromatic blend comprising a compound essential oil and an aromatic masterbatch infused in the compound essential oil; the mass ratio of the aromatic masterbatch to the compound essential oil is 5:2-3.

[0033] The compound essential oil is composed of 20% to 70% camphor oil, 5% to 60% aromatic camphor oil, 1% to 15% litsea cubeba oil, and 0.5% to 20% peppermint oil by mass; the purity of the camphor oil, the aromatic camphor oil, the litsea cubeba oil, and the peppermint oil is greater than or equal to 90%.

[0034] The aromatic masterbatch is made by mixing and kneading mugwort, camphor leaves, agastache rugosa, lavender, and patchouli into irregular flakes; the aromatic masterbatch is mixed in the following proportions by weight: 20 to 30 parts of mugwort, 25 to 35 parts of camphor leaves, 10 to 20 parts of agastache rugosa, 10 to 20 parts of lavender, and 20 to 30 parts of patchouli; the moisture content of mugwort, camphor leaves, agastache rugosa, lavender, and patchouli is less than or equal to 15%.

[0035] A method for preparing a herbal aromatic mixture includes the following steps:

[0036] Step 1: Mix 20 to 30 parts by weight of Artemisia argyi, 25 to 35 parts by weight of Cinnamomum camphora, 10 to 20 parts by weight of Eupatorium fortunei, 10 to 20 parts by weight of Lavender, and 20 to 30 parts by weight of Patchouli to obtain aromatic masterbatch.

[0037] Step 2: Knead the aromatic masterbatch into irregular flakes, then pour it into a double-layered ceramic or glass container and gently press it flat.

[0038] Step 3: Mix camphor oil (20%-70% by weight), aromatic camphor oil (5%-60%), litsea cubeba oil (1%-15%), and peppermint oil (0.5%-20%) to form a compound essential oil.

[0039] Step 4: Pour the compound essential oil into the storage container according to the mass ratio of aromatic masterbatch to compound essential oil of 5:2-3; control the amount of aromatic masterbatch and compound essential oil so that they can just fill the storage container.

[0040] Step 5: Using the static capping soaking method, the herbal aromatic mixture is obtained by soaking for 2-5 days through the reaction of the double-combination permeation soaking and the mother-child coupling.

[0041] In this process, the mugwort, camphor leaves, agastache, lavender, and patchouli are extracted by temperatureless distillation to obtain oils with a moisture content of less than 15%. The extracted oils are used in the composition of the compound essential oil in step three.

[0042] The core innovation of this patent lies in its two sets of homogeneous gene chains, using different distilled oils and homogeneous herbal medicinal materials, referred to as the "mother-child soaking method." The daughter material is essentially an essential oil with multiple disinfecting, antiviral, and purifying properties. The second formula uses natural herbal plants (also belonging to the agricultural, forestry, and woody families, extracts of high-quality aromatic chemical materials). However, this technical solution uses a combination of raw, dried herb mother material (undistilled) and daughter material soaking, with the daughter material's aromatic oil homogeneous gene components penetrating the mother material through the soaking process. This dual-strength synthesis is an innovative technology. It also saves on the costly, rapid evaporation of oils found in four-in-one products. It solves the problem of dual-effect, multi-functional soaking and penetration of different homogeneous materials. The above two-component formulation method uses five flavors from the mother material and four flavors from the daughter material's oils, synthesizing a total of nine plant-based aromatic hydrocarbon antiviral systems.

[0043] In specific applications, such as the aseptic recycling of face masks, the adsorption of fragrances from fabric decorations, and the use of porous materials (such as sponges) in environments like cars and indoors, these applications can release various fragrances from the permeated materials inside the bottle, thus producing a pleasant aroma with antiviral, antibacterial, and air-purifying effects.

[0044] Conventional essential oils or blended essential oils have poor aroma persistence: In the event of accidental leakage, conventional or blended essential oils evaporate rapidly, meaning 100 grams of product may completely evaporate within ten days, resulting in significant resource waste. Furthermore, conventional or blended essential oils pose safety hazards when applied externally or inhaled, such as potential contact with children's eyes. However, the herbal aromatic blend liquid essential oil of this invention offers convenience in practical application. It can be applied topically or used for olfactory stimulation to refresh the mind, similar to the use of a traditional snuff bottle, providing a convenient user experience. Experimental comparisons show that 100 grams of blended essential oil evaporates completely within 20 to 30 days after opening, while the same weight of the aromatic blend extends the aroma period to 60 to 90 days, with superior effects compared to aromatic masterbatches or blended essential oils, thus optimizing the therapeutic effect.

[0045] Comprehensive Advantages Analysis: Porcelain or glass bottles possess the preservation characteristics of being non-plasticized, non-oxidized, and releasing no volatile substances. Their double-layered structure makes them suitable for a wide range of applications, including in vehicles, indoors, restrooms, and offices. Each bottle is equipped with a large-diameter, lightweight, decorative cap. When not in use, the cap can be opened, and a cloth pendant placed at the bottle opening can absorb the fragrance, making it suitable as a chest ornament. Alternatively, a mask can be placed over the bottle opening to absorb the fragrance and then disinfected, allowing for reuse of disposable masks.

[0046] Virus inactivation effect test

[0047] The evaluation criteria for virus inactivation in air disinfection were conducted according to Section 2.1.3 of the "Disinfection Technical Specifications" (2002 edition). In the experiment, influenza A virus strain H3N2 (ATCC VR-1679) was selected as the test virus, canine kidney cells (MDCK) were used as the host cell line, and a 2-hour contact time was set to determine the inactivation effect. Preliminary test results showed that the corrected inactivation rate of the sample against the natural decay interference of airborne microorganisms reached 94.11%. After testing the second sample numbered 799.99, an antiviral activity rate as high as 99.98% was found. These experimental results demonstrate that the novel aromatic essential oil developed by our research team has significant air purification capabilities. See Table 1 below.

[0048]

[0049] Table 1. Results of the airborne virus removal effect test

[0050] Safety inspection:

[0051] I. Acute oral toxicity test:

[0052] 1. Laboratory animals and rearing environment: SPF grade KM mice: 10 males and 10 females, weighing 18-22g (feed source: rice, with feed qualification certificate; rearing environment: temperature 20-26℃, relative humidity 40-70%).

[0053] 2. Methods: Before the experiment, the experimental animals were fasted overnight, but water intake was not restricted.

Fasting continued for 3 days after gavage, followed by a normal diet. Individual and comprehensive records were kept for each animal after administration, observing signs of poisoning and mortality. A thorough examination was conducted daily, with weight measured on days 0, 7, and 14 after administration. The observation period was 14 days.

[0054] 3. Results Evaluation: In terms of toxicological assessment, acute oral toxicity test, acute inhalation toxicity test and intact skin irritation test in rats confirmed that no deaths or toxic reactions occurred in the experimental animals (mortality rate 0%).

[0055]

[0056] Note: No obvious symptoms of poisoning or death were observed in any of the test animals during the 14-day observation period.

[0057] Skin toxicity test

[0058] 1. Laboratory animals and housing environment: Animal species and strain: Common grade New Zealand rabbits: 3 females: weight range: 2.0-2.2kg, housing environment: temperature 20-26℃, relative humidity 40-70%.

[0059] 2. Method: 24 hours prior to the experiment, the hair on both sides of the spine on the back of the rabbits was removed, with the hair removal area approximately 3cm x 3cm on each side. The next day, 0.5ml of the test substance was applied directly to one side of the skin, covered with a layer of non-irritating plastic film, and then secured with non-irritating adhesive tape. The other side of the skin served as a blank control. A closed-cell test was used, with the application time being 4 hours. After the experiment, any remaining test substance was removed with warm water.

[0060] 3. Result Evaluation: Skin reactions at the test sites were observed at 1 h, 24 h, and 48 h after removal of the test substance, and skin reactions were scored according to the skin irritation response scoring table. Based on the average of the highest scores at each observation point at 1 h, 24 h, and 48 h, the skin irritation intensity was determined according to the skin irritation intensity grading standard table.

[0061]

[0062] This invention proposes a method for preparing dried medicinal materials based on five herbs, including Artemisia argyi, Eupatorium fortunei, Lavender, Cinnamomum camphora leaves, and Pogostemon cablin. The method involves drying these herbs by mechanical kneading or maintaining their original leaf shape, followed by a soaking and permeation process using a device. Under light-protected conditions, the herbal raw materials undergo a chemical reaction in the soaking environment, typically for 2 to 5 days. After soaking, the herbs are metered and packaged using aseptic equipment. The packaging bottles are made of materials such as glass or ceramic to protect the chronic circulatory system.

[0063] This invention further proposes two formulation synthesis schemes designed to ensure safety and chronic volatility while maintaining aroma persistence. The five-herb medicine itself possesses natural antibacterial and antiviral properties and belongs to the category of five-herb medicinal preparations.

[0064] The innovative feature of the two-component synthesis lies in preventing the rapid waste caused by oil leakage and evaporation. Through this two-component synthesis technology, two key benefits are achieved: first, it extends the shelf life due to slow-release evaporation and leakage during storage; second, it exhibits adsorption properties for various materials, such as fabric pendants and disposable masks. After adsorption and virus elimination, disposable masks can be recycled, resulting in significant energy savings (tests have been conducted on masks to detect sterility). Sponge-like materials can also be used for absorption.

[0065] This method achieves antiviral, disinfection, insect-proofing, and anti-corrosion effects. Its aromatic hydrocarbon components have a positive effect on the human sense of smell, refreshing the mind and clearing the meridians. It can replace the snuff bottles used by ancient nobles, and has the effects of refreshing the mind, enhancing lung and spleen function, and improving the immune system, ensuring effective human health and therapeutic benefits.

[0066] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
