Description

Technical Field

[0001] The invention relates to the technical field of essential oil patches, and in particular to a slow-release sleep-aiding essential oil patch and an essential oil formula. Background Art

[0002] The pace of life in modern society is fast, and people are prone to insomnia for various reasons. For example, high work pressure or heavy study burden may cause anxiety and tension, thus affecting sleep quality; irregular work and rest will disrupt the body's biological clock, making it difficult to fall asleep at night; noise, light, bed comfort and indoor temperature may also affect sleep; in addition, some physiological factors such as chronic diseases may affect sleep. At present, the methods for treating insomnia mainly include non-drug treatment and drug treatment. For patients with mild insomnia symptoms, sleep quality can be improved by adjusting the sleeping environment, improving living habits and psychological treatment, but the effect is often not ideal. For patients with more severe insomnia symptoms, if non-drug treatment is not ideal, they also need to be treated with drugs such as sleeping pills, antianxiety drugs and antidepressants, but long-term drug treatment may cause drug dependence and side effects.

[0003] In addition to the above treatment methods, aromatherapy is also included. Some aromatic plant essential oils have a calming effect and can help with sleep, eliminate fatigue and relieve stress, and further help with sleep. Essential oils extracted from aromatic plants are mainly absorbed into the body through the respiratory tract or skin. Currently, most of them enter the body through the respiratory tract, using the aromatic molecules in plant essential oils to stimulate the olfactory nerves, which can affect the central nervous system and achieve the effect of regulating emotions and improving sleep. In the process of using essential oils, they are often volatilized by sprinkling them on fabrics or through field bottles, but the above methods will cause the essential oils to evaporate too quickly. If the fragrance is too strong for a period of time, it will cause certain irritation and damage to the human respiratory system. Not only is the effect of use poor, but it cannot produce a lasting effect.

[0004] Therefore, there is an urgent need in the art to provide a sustained-release sleep-aiding essential oil patch and an essential oil formula to solve the defects of the prior art. Summary of the invention

[0005] The purpose of the present invention is to provide a slow-release sleep-aiding essential oil patch, which has a simple structure and is easy to implement. By encapsulating the sleep-aiding essential oil in the form of microcapsules, the sleep-aiding essential oil can be slowly released, the fragrance can be retained continuously, and the human body can sleep.

[0006] To achieve the above-mentioned purpose, the present invention provides a sustained-release sleep-aiding essential oil patch, which comprises a surface layer, an essential oil layer, an isolation layer, an adhesive layer and a protective layer from top to bottom; wherein the essential oil layer contains sustained-release microcapsules, and the sustained-release microcapsules include microcapsule wall materials and a sustained-release sleep-aiding essential oil core material wrapped inside the microcapsule wall materials.

[0007] Furthermore, a heating layer is provided between the isolation layer and the adhesive layer, and the heating layer includes a packaging bag and a heating material filled in the packaging bag; the packaging bag is a non-woven bag, and the heating material includes iron powder, activated carbon, vermiculite, salt and water.

[0008] Furthermore, the surface layer material is a breathable non-woven fabric or a woven fabric.

[0009] Furthermore, the isolation layer is one of tin foil, coated paper or glassine paper.

[0010] Furthermore, an oleophobic breathable membrane is provided between the essential oil layer and the surface layer.

[0011] The slow-release sleep-aiding essential oil patch of the present invention needs to be sealed in a packaging bag when not in use to prevent contact with air, which may cause the essential oil to volatilize and the heating material in the heating layer to react with air.

[0012] The surface material is a breathable material, which is convenient for the release of the sleep-aiding essential oil and the circulation of air during use. Different patterns and words can be printed on the surface of the surface material. In actual design, the type of essential oil can be selected according to actual needs. The patterns and words are different according to the type of essential oil. Consumers can distinguish different types of essential oils according to the patterns and words printed on the surface when choosing.

[0013] The essential oil layer is mainly used to store essential oils. The material of the essential oil layer can be selected from medical non-woven fabrics, knitted fabrics, spun fibers or other special fabrics (such as coated fabrics or fabrics containing microporous structures, etc.). The above-mentioned non-woven fabrics all contain pores, and the microcapsules enter the pores of the above-mentioned fabrics, which have good durability and stability, and can ensure that the essential oil in the microcapsules is slowly released over a long period of time. The fabric of the preferred essential oil layer of the present invention is a medical non-woven fabric, which, in addition to having the advantages of moisture-proof, breathable, flexible and non-toxic, has a certain viscosity and can better wrap the microcapsules. In addition, the fabric of the medical non-woven fabric is soft and has very small pores, so the microcapsules are not easy to leak out from the pores of the fabric, but the essential oil molecules can be released.

[0014] The isolation layer is arranged below the essential oil layer to prevent the essential oil from penetrating downwards, ensuring that the essential oil is released and penetrates into the surface layer, thereby playing a sleep-inducing role after being absorbed by the human body.

[0015] The adhesive layer mainly plays the role of adhesion. When it is needed, the adhesive layer can be directly attached to the corresponding object. Since the product of the present invention mainly plays the role of helping sleep, when in use, the adhesive layer is preferably attached to the head of the bed, pillow or clothing to prevent it from falling off during use.

[0016] The protective layer is mainly used to protect the adhesive layer to prevent it from losing its adhesive force, and its material is a common material in the prior art. In the present invention, the adhesive layer can be exposed after tearing off the protective layer. The materials of the adhesive layer and the protective layer have the same functions as the gelatin layer and the adhesive paper on the warm baby in the prior art, and the raw materials can directly select the gelatin layer and the adhesive paper on the warm baby in the prior art.

[0017] The heating material in the present invention is similar to the ingredients of commercially available warm baby, including iron powder, activated carbon, vermiculite, salt and water. The heating material in the present invention can undergo an exothermic reaction under the action of oxygen in the air, so that the microcapsule wall material is ruptured by heat, thereby releasing the sleep-aiding essential oil. In the heating material in the present invention, the weight parts of the raw materials are: 70-72 parts of iron powder, 11-13 parts of activated carbon, 5-8 parts of vermiculite, 2-3 parts of salt and 3-6 parts of water.

[0018] The wall material of the microcapsule is a thermosensitive substance, such as poly N-isopropylacrylamide and acrylamide, etc. These materials are sensitive to temperature changes and can undergo corresponding physical or chemical changes as the temperature changes. When the temperature is low, the gaps on the surface of the wall material are blocked to prevent the release of the sleep-aiding essential oil; when the heating material of the heating layer releases heat, the gaps on the surface of the wall material are exposed, and the sleep-aiding essential oil is released through the gaps on the surface of the wall material. Specifically, the preferred wall material of the present invention is hydroxypropyl cellulose and poly N-isopropylacrylamide grafted polymerized. When the temperature is low, the poly N-isopropylacrylamide grafted chains are fully stretched and cross-covered with each other, blocking the gaps on the surface of the wall material to prevent the release of the sleep-aiding essential oil; when the heating material of the heating layer releases heat, the poly N-isopropylacrylamide grafted chains shrink so that the gaps on the surface of the wall material are exposed to form a release channel for the sleep-aiding essential oil, and the sleep-aiding essential oil is released through the gaps on the surface of the wall material.

[0019] The oleophobic breathable membrane provided between the essential oil layer and the surface layer has good air permeability, which can ensure that air and essential oil can pass smoothly. When releasing the sleep-aiding essential oil, the oleophobic breathable membrane of the present invention can limit the volatilization speed of the essential oil, thereby realizing the slow and continuous release of the sleep-aiding essential oil. The oleophobic breathable membrane of the present invention is preferably an expanded polytetrafluoroethylene membrane, which has a spider web-like microporous structure, and the pores allow the released essential oil molecules to pass through, thereby playing a role of slow release.

[0020] Another object of the present invention is to provide a sustained-release sleep-aiding essential oil formula, the raw materials of which are all extracted from plants and contain a variety of active ingredients. While playing a sleep-aiding role, it can also have positive effects on the human body such as antibacterial and anti-inflammatory effects.

[0021] To achieve the above object, the present invention provides a sustained-release sleep-aiding essential oil formula, comprising the following raw materials in parts by weight: 15-20 parts of lavender essential oil, 8-10 parts of sandalwood essential oil, 3-6 parts of geranium essential oil, 5-8 parts of bergamot fruit essential oil, 0.5-1 part of vetiver root essential oil, 1-2 parts of rose essential oil, 1-2 parts of eucalyptus globulus leaf essential oil, 0.3-0.8 parts of frankincense essential oil and 0.5-1 part of manuka essential oil.

[0022] The slow-release sleep-aiding essential oil in the present invention is the core material in the slow-release microcapsule, and the essential oil in the present invention is processed into a small molecule nanostructure. During the preparation, the essential oil raw material can be prepared by emulsification technology to obtain the nano essential oil.

[0023] Lavender essential oil contains compounds such as linalyl acetate, linalool, lavandinol and lavandin acetate, which together constitute the unique aroma and sleep-inducing effect of lavender essential oil. The sleep-inducing ingredients in lavender essential oil can improve sleep quality by regulating the human nervous system and endocrine system, relieving tension, anxiety and stress.

[0024] Sandalwood essential oil can act on the human nervous system, regulate the release of neurotransmitters and the excitability of neurons, and gradually relax the body from a tense state, thereby improving sleep quality. In addition, the aroma of sandalwood essential oil can stimulate the olfactory nerves and act on the emotional center of the brain, making the body happy and relaxed, and further improving sleep quality.

[0025] The aroma molecules of bergamot essential oil can be transmitted to the central nervous system of the brain through the olfactory system, producing a calming and relaxing effect on the brain, thereby helping to improve sleep quality.

[0026] Geranium essential oil has a certain central nervous system inhibitory effect, which can relax people and relieve tension and anxiety, thus helping to improve sleep quality. The active ingredients in geranium have an affinity for 5-hydroxytryptamine receptors, which can increase the concentration of serotonin in the brain and produce an antidepressant effect. This has a certain effect on alleviating insomnia caused by depression.

[0027] When the lavender essential oil, bergamot fruit essential oil and geranium essential oil in the present invention are used in conjunction, they can enhance each other's effects and further improve the sleep-aiding effect. Lavender essential oil, bergamot fruit essential oil and geranium essential oil can enhance each other's effects in promoting sleep. The sedative and tranquilizing effect of lavender combined with the soothing effect of bergamot fruit can more effectively relieve stress and anxiety; and the anti-depressant and neurotransmitter-regulating effects of geranium can further help people relax and enter deep sleep. When these three essential oils are used in conjunction, sleep quality can be comprehensively improved in multiple aspects. Not only can they help people fall asleep more easily, but they can also prolong deep sleep time and improve the overall quality of sleep.

[0028] Vetiver essential oil is rich in active ingredients such as sesquiterpenes. Sesquiterpenes can effectively regulate the nervous system. By promoting the release of γ-aminobutyric acid in the brain, it can calm nerves and stabilize emotions, thereby reducing the symptoms of dreaminess caused by stress or anxiety.

[0029] The geranium essential oil and vetiver essential oil of the present invention both have a sedative effect, and when the two are used in synergy, the effect can be further enhanced, so that people can enter a deep sleep state faster. Vetiver essential oil can regulate the nervous system, while geranium essential oil can promote blood circulation. The synergistic effect of the two can promote overall relaxation of the body and improve sleep quality.

[0030] The unique aromatic components in rose essential oil can penetrate deep into the brain and regulate the levels of neurotransmitters such as serotonin and dopamine. By regulating the levels of these neurotransmitters, rose essential oil helps relieve depression and anxiety, thereby helping to improve sleep quality. The aroma of rose essential oil can also improve the sleeping environment and create a peaceful and comfortable atmosphere. This atmosphere helps people relax and reduce anxiety and restlessness before going to bed, thereby helping to improve sleep quality.

[0031] Eucalyptus globulus essential oil contains a wealth of active ingredients, such as eucalyptol, eucalyptol, eucalyptone and eucalyptol, which can promote the release of the neurotransmitter γ-aminobutyric acid (GABA), thereby helping to reduce the activity of the nervous system and making it easier for people to enter a resting state. Eucalyptus globulus essential oil can also regulate the body's hormone secretion, such as inhibiting the production of cortisol, which is a hormone related to stress response. Reducing its level helps relieve stress and anxiety, thereby helping sleep.

[0032] Frankincense essential oil has a warm, woody, smoky scent that can be soothing. When inhaled, it stimulates the brain to release neurotransmitters such as endorphins and serotonin. These neurotransmitters play an important role in regulating mood and reducing anxiety, which helps people sleep better.

[0033] Manuka essential oil has a unique aroma that can stimulate the human body's olfactory nerves and then transmit to the emotional center of the brain, producing a feeling of pleasure and relaxation. After inhaling Manuka essential oil into the body, it can help people relieve psychological stress, reduce anxiety and tension, and thus help sleep.

[0034] The rose essential oil, eucalyptus globulus leaf essential oil, frankincense essential oil and manuka essential oil of the present invention all have the effect of relieving tension and anxiety, and the effect is more remarkable when the four act together. The rose essential oil and eucalyptus globulus leaf essential oil synergistically can regulate the work of the nervous system, help to reduce the awakening period, and extend the sleep duration. The frankincense essential oil and manuka essential oil synergistically can directly regulate insomnia symptoms and improve sleep quality.

[0035] The method for using the slow-release sleep-aiding essential oil patch of the present invention is as follows: the essential oil patch of the present invention needs to be sealed in a packaging bag before use. When using, the sealed bag is directly torn open, the protective layer is torn off, and the adhesive layer is placed on the bedside, pillow or clothes.

[0036] The essential oil in the present invention is a composite essential oil, and the raw materials in the composite essential oil are processed into a small molecule structure. After the essential oil patch releases the small molecule essential oil, the small molecule essential oil can enter the human body through the respiratory mucosa. The essential oil molecules can quickly contact the respiratory mucosa, and the respiratory mucosa has abundant capillaries and lymphatic vessels. The essential oil molecules penetrate into the blood circulation system through these blood vessels and lymphatic vessels, and then are distributed to various tissues and organs throughout the body to be absorbed and utilized by the human body, thereby exerting their efficacy.

[0037] The beneficial effects of the present invention are:

[0038] 1. The slow-release sleep-aiding essential oil patch of the present invention has a simple structure and is easy to implement. By encapsulating the sleep-aiding essential oil in the form of microcapsules, the sleep-aiding essential oil can be slowly released, leaving a lasting fragrance and assisting human sleep. The oleophobic breathable membrane in the present invention can limit the volatilization speed of the essential oil, further achieving the slow and continuous release of the sleep-aiding essential oil;

[0039] 2. The raw materials of the sustained-release sleep-aiding essential oils in the present invention are all natural essential oils, which will not cause drug dependence and side effects. In addition, the raw materials of the essential oils in the present invention are all processed into small molecule structures. The small molecule essential oils can quickly contact the respiratory mucosa and penetrate into the blood circulation system through the blood vessels and lymphatic vessels to exert their effects. They are quick in effect and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Table 1 Comparison of specific dosages of the composite essential oil formula in Examples 1-5

[0050]

[0051] Example 1-5 Sleeping aid effect test

[0052] 60 volunteers aged 25-55 were randomly selected to participate in the test, half of them were male and half were female, and they were evenly divided into 6 groups, each with 10 people and half of them were male and half were female. The 6 groups were named experimental groups 1-5 and comparison groups. The sustained-release sleep-aiding essential oil patches of Examples 1-5 were tested for sleep-aiding effects, and a sleep-aiding essential oil patch on the market was randomly selected for comparison.

[0053] To ensure that the rest time of each group of volunteers is basically the same, each group of volunteers began to stick the essential oil patch on the pillow 30 minutes before going to bed, wherein the experimental groups 1-5 used the essential oil patches of Examples 1-5 of the present invention respectively, and the control group used the randomly selected essential oil patch.

[0054] The Pittsburgh Sleep Quality Index (PSQI) was used to ensure that the baseline levels of each group were similar. The sleep monitors were used continuously for 14 days and the PSQI scores were calculated every 7 days. The specific test results of each group are shown in Table 2 below.

[0055] Table 2 Test results of experimental groups 1-5 and comparison group

[0056]

[0057] According to the results in Table 2, the average improvement rate of each group in experimental groups 1-5 on the 14th day was above 44%, while the improvement rate of the control group was only 25.22%. It can be seen that the sleep-aiding essential oil of the present invention can significantly improve sleep quality. Among experimental groups 1-5, experimental group 3 has the highest improvement efficiency. Therefore, in Examples 1-5, the present invention uses Example 3 corresponding to Experimental Group 3 as the best example.

[0058] Embodiment 6-9

[0059] In the composite essential oil of the present invention, lavender essential oil and sandalwood essential oil play a major role. To further verify the optimal mixing ratio of lavender and sandalwood essential oil, the present invention also designs Examples 6-9 based on Example 3. The structures of the essential oil patches and the types of essential oil formulas used in Examples 6-9 and Example 3 are exactly the same, and the only difference is that the lavender essential oil and sandalwood essential oil in the essential oil formulas of Examples 6-9 are different from those in Example 3 corresponding to the experimental group, and the differences between the essential oil formulas of Examples 6-9 and Example 3 are specifically shown in Table 3 below.

[0060] Table 3 Comparison of specific dosages of the composite essential oil formulas in Example 3 and Examples 6-9

[0061]

[0062]

[0063] Example 6-9 Sleeping aid effect test

[0064] 40 volunteers aged 25-55 were randomly selected to participate in the test, half of them were male and half were female. They were evenly divided into 4 groups, with 10 people in each group and half of them were male and female. The 4 groups were named Experimental Groups 6-9.

[0065] To ensure that the rest time of each group of volunteers is basically the same, each group of volunteers began to stick the essential oil patch on the pillow 30 minutes before going to bed, among which, the experimental groups 6-9 used the essential oil patch of Examples 6-9 of the present invention respectively.

[0066] The Pittsburgh Sleep Quality Index (PSQI) was used to ensure that the baseline levels of each group were similar. The sleep monitors were used continuously for 14 days and the PSQI scores were calculated every 7 days. The specific test results of each group are shown in Table 4 below.

[0067] Table 4 Test results of experimental group 3 and experimental groups 6-9

[0068]

[0069] According to the results in Table 4 above, it can be seen that experimental group 3 and experimental groups 6-9 of the present invention can improve sleep, and according to the results of experimental group 3 and experimental groups 6-9, it can be seen that on the basis of the same amount of other essential oils, the ratio of lavender essential oil to sandalwood essential oil is 2:1, which has the best effect.

[0070] Although the products of Examples 1-9 of the present invention can significantly improve sleep quality, the effect is still not ideal, so the present invention also designs Examples 10-12.

[0071] Examples 10-12

[0072] The structures of Examples 10-12 are exactly the same as those of Example 3, the only difference being the type and specific amount of the composite essential oil formula. Specifically, compared with Example 3, Examples 10-12 further include the following raw materials in parts by weight: 0.5-1 part of ylang-ylang essential oil and 1-2 parts of patchouli essential oil.

[0073] The aroma of ylang-ylang essential oil can stimulate the emotional center in the brain through the olfactory nerve, thereby helping to relieve some mild tension and anxiety. This relaxing effect helps people to fall asleep more easily and improve sleep quality. The synergistic effect of the lavender essential oil, sandalwood essential oil and ylang-ylang essential oil in the present invention helps to relax the body and mind and help the human body enter deep sleep.

[0074] Patchouli essential oil has a soothing and calming effect, and can relieve negative emotions such as anxiety, tension, and stress, which are often important factors leading to insomnia. By regulating emotions, patchouli essential oil can help people relax their body and mind, making it easier to enter a deep sleep state and improve sleep efficiency.

[0075] Patchouli essential oil and vetiver essential oil in the present invention both have significant sedative effects, can act together on the central nervous system, reduce anxiety and stress levels, and thus help to fall asleep faster. Ylang-ylang essential oil has the effect of soothing emotions, can relax the body and mind, and further promote sleep. Ylang-ylang essential oil is used in coordination with patchouli essential oil and vetiver essential oil to double this relaxation effect. In the present invention, the coordinated use of patchouli essential oil, ylang-ylang essential oil and vetiver not only helps to fall asleep, but also can improve sleep depth and quality, reduce the number of times of waking up at night, and ensure a good night's sleep.

[0076] The specific dosage comparison of the composite essential oil formula in Examples 10-12 is shown in Table 5 below.

[0081] 30 volunteers aged 25-55 were randomly selected to participate in the test, half of them were male and half were female, and they were evenly divided into 3 groups, each with 10 people and half of them were male and half were female, and the 3 groups were named experimental groups 10-12. The slow-release sleep-aiding essential oil patches of Examples 10-12 were tested for sleep-aiding effects.

[0082] To ensure that each group of volunteers had basically the same work and rest time, each group of volunteers began to stick the essential oil patch on the pillow 30 minutes before going to bed. Experimental groups 10-12 used the essential oil patch of Examples 10-12 of the present invention, respectively.

[0083] The Pittsburgh Sleep Quality Index (PSQI) was used to ensure that the baseline levels of each group were similar. The test was used continuously for 14 days, and the PSQI scores were calculated every 7 days. The comparative data of each group were compared with the data of experimental group 3. The specific test results of each group are shown in Table 6 below.

[0084] Table 6 Test results of experimental group 3 and test groups 10-12

[0085]

[0086] According to the results in Table 6, experimental groups 10-12 have better improvement effects than experimental group 3, and the average PSQI scores of experimental groups 10-12 are all lower than 5 points, indicating good sleep quality. Among experimental groups 10-12, experimental group 10 has the highest improvement efficiency. Therefore, among embodiments 10-12, the present invention uses embodiment 10 corresponding to experimental group 10 as the best embodiment.

[0087] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the present invention.
