Description

Technical Field

[0001] The present application relates to the field of daily chemical fragrance essential oils, and more specifically, to a daily chemical fragrance essential oil containing orange blossom and a preparation method thereof. Background Art

[0002] With the accelerated pace of modern life and the increase of work pressure, more and more people are facing sleep problems, such as insomnia, poor sleep quality, etc. Good sleep is essential for human health, it helps to restore body functions, strengthen the immune system and improve the quality of life.

[0003] Existing sleep aid products mostly rely on drug ingredients, such as benzodiazepines, which may cause dependence, side effects, and even potential risks to human health if used for a long time. Seeking a natural, safe, and effective sleep aid product has become a research focus in the industry.

[0004] As a natural plant extract, essential oils have unique aroma and physiological activity and are widely used in cosmetics, skin care products and fragrance products. Currently, most of the daily chemical fragrance products on the market are mainly based on beauty and aroma, and relatively few are developed for sleep-aiding functions. At the same time, how to effectively apply natural plant essential oils with sleep-aiding effects to daily chemical fragrances so that they can maintain their original aroma characteristics and play a sleep-aiding role is a technical challenge faced by the industry. Therefore, the development of a daily chemical fragrance essential oil with sleep-aiding effects has become an urgent need in the current market. Summary of the invention

[0005] In order to meet the market demand for natural and healthy sleep-aiding products, the present invention proposes a daily chemical fragrance essential oil containing orange blossom with sleep-aiding effect and a preparation method thereof. The essential oil is intended to help users improve sleep quality and relieve sleep problems such as insomnia through the aroma and physiological activity of natural plant extracts, while avoiding the side effects and dependence that may be caused by drug ingredients.

[0006] In the first aspect, the present application provides a daily chemical fragrance essential oil containing orange blossom, adopting the following technical scheme: a daily chemical fragrance essential oil containing orange blossom, comprising the following raw materials in parts by mass: 30-50 parts of orange blossom essential oil, 1-5 parts of tangerine oil, and 30-50 parts of bitter orange essential oil.

[0007] By adopting the above technical scheme, with bitter orange leaves, red oranges and orange blossoms as the main ingredients, agarwood acetate with a strong sedative and soothing effect on the nervous system is extracted, and flavonoids, lactones, and narcotine, which are effective in soothing the liver and relieving depression, play a strong sedative and soothing role, can relax tense emotions, and can also adjust emotional disorders and anxiety caused by liver qi disorder. This fragrance raw material has a delicate and light citrus fragrance, and a hint of natural sweet floral fragrance, but there is no sense of frivolity. The flowers are white and the fragrance is warm and elegant. It is a smell that makes people feel happy.

[0008] Specifically, the daily chemical essential oil containing orange blossom provided in this application has the following effects:

[0009] Promotes Relaxation: This product has excellent calming and relaxing effects. It can help reduce anxiety, tension and stress, creating a peaceful state of mind for sleep.

[0010] Improve sleep quality: This product helps you to fall into deep sleep, thus improving your sleep quality. It can effectively reduce the number of times you wake up at night and enjoy a more peaceful night.

[0011] Relieves Insomnia Symptoms: For those who often experience insomnia symptoms, the use of this product can reduce problems with falling asleep, staying awake, and anxiety.

[0012] Relieves depressive symptoms: This product is believed to help boost mood and reduce depressive symptoms, thereby improving overall mental health.

[0013] Preferably, in terms of weight percentage, the daily chemical fragrance essential oil containing orange blossom also includes 1-5 parts of jasmine essential oil, 10-20 parts of Roman chamomile essential oil, and 10-20 parts of bergamot oil.

[0014] By adopting the above technical scheme, jasmine essential oil, Roman chamomile essential oil, bergamot oil are used together with orange blossom essential oil, tangerine oil and bitter orange essential oil to further enrich the taste of daily chemical fragrance essential oil containing orange blossom, making its taste more harmonious. After inhalation, the user has a good sense of pleasure and no rejection, thereby giving full play to the sleep-aiding effect.

[0015] Preferably, the preparation method of bergamot oil comprises the following steps:

[0016] Step 1: Mix the calcium hydroxide aqueous solution, rosemary extract and grape seed extract until uniform to obtain a soaking solution; Step 2: Mix the bergamot peel with the soaking solution and soak for 1-3 hours;

[0017] Step 3: Take out the soaked bergamot peel and squeeze it to obtain an oil-water mixture;

[0018] Step 4: Centrifuge the oil-water mixture to obtain bergamot oil.

[0019] Daily chemical fragrance oils containing orange blossom are composed of essential oil raw materials, including limonene, citral and other substances. These ingredients will become unstable in light, high temperature and other environments, and are prone to chemical reactions or decomposition, resulting in the loss of active ingredients in daily chemical fragrance oils containing orange blossom, thus affecting its aroma, harmony, sleep-aiding effect, etc. A humid environment (especially in severe conditions such as the return of the south wind in Guangdong) will lead to an increase in moisture, which may react with the chemical components in daily chemical fragrance oils containing orange blossoms, also resulting in a decline in quality.

[0020] By adopting the above technical scheme, the soaking solution is prepared by mixing rosemary extract, grape seed extract and calcium hydroxide aqueous solution. The bergamot peel is fully in contact with the soaking solution, and the calcium hydroxide aqueous solution softens the cell wall of the bergamot peel, so that the cell wall can be more easily broken during subsequent squeezing, releasing more active substances. During the soaking period, the rosemary extract and grape seed extract penetrate into the bergamot peel and remain inside. If the excessive softening of the calcium hydroxide aqueous solution causes a small amount of aroma factors to escape prematurely, the rosemary extract and grape seed extract can also play a certain role in hindering the escape of the aroma factors and reducing losses.

[0021] The rosemary extract and grape seed extract attached to the bergamot peel are squeezed together with the subsequent process, combining with the free radicals in some bergamot oil to form stable compounds, terminating the free radical chain reaction, and reducing the generation of oxidation products. It can effectively protect the aroma factors of the squeezed bergamot oil from being destroyed and inhibit the oxidation reaction of bergamot oil, thereby improving stability.

[0022] The co-pressing of rosemary extract, grape seed extract and bergamot peel can enrich the aroma of bergamot oil, make the daily chemical fragrance oil containing orange blossom more harmonious as a whole, and help to promote sleep. In addition, the bergamot oil prepared in this way has higher stability, reduces the influence of humidity, high temperature and light on it, and ensures that the daily chemical fragrance oil containing orange blossom can play a good role for a long time.

[0023] Preferably, the mass ratio of the bergamot peel to the soaking solution is 1:(2-5).

[0024] By adopting the above technical solution, the mass ratio of the bergamot peel to the soaking solution is further limited, so that the bergamot peel is fully soaked and the soaking solution can infiltrate the interior of the bergamot peel.

[0025] Preferably, according to the mass percentage of the soaking solution, the rosemary extract is 3-8%, the grape seed extract is 3-8%, and the calcium hydroxide aqueous solution makes up the balance.

[0026] By adopting the above technical scheme, the dosage coordination relationship between rosemary extract, grape seed extract and bergamot peel is further limited, so that the rosemary extract and grape seed extract can be more fully attached to the bergamot peel, thereby playing a role in protecting the aroma factors.

[0027] Moreover, if the ratio of the three is unbalanced, it is easy to over-react with certain components in the bergamot peel, thereby destroying the flavor characteristics of the final bergamot oil. Under this dosage limit, the prepared bergamot oil has a better fragrance synergistic effect with other raw materials and can also maintain a good storage effect.

[0028] Preferably, the concentration of the calcium hydroxide aqueous solution is 1-5%.

[0029] Preferably, in step 2, the bergamot peel is mixed with the soaking solution, and microwaved at 300-400 W for 60-120 s, left standing for 30-60 s after the microwave treatment, and then microwaved again at 300-400 W for 60-120 s; and then left standing and soaked for 1-3 h.

[0030] By adopting the above technical solution, when soaking the bergamot peel, a specific microwave method is used for treatment, which can promote more rosemary extract and grape seed extract to penetrate deeper into the interior of the bergamot peel, thereby facilitating subsequent reactions.

[0031] In a second aspect, the present application provides a method for preparing a daily chemical fragrance essential oil containing orange blossom, using the following technical solution:

[0032] A method for preparing daily chemical essential oil containing orange blossom comprises the following steps: mixing raw materials until they are uniform to obtain the daily chemical essential oil containing orange blossom.

[0033] In summary, this application has the following beneficial effects:

[0034] 1. Since the present application adopts bitter orange leaves, red oranges and orange blossoms as main ingredients, the prepared essential oil can play a strong sedative and soothing role, can relax tense emotions, and can also adjust emotional disorders and anxiety caused by liver qi disorder, and has a good sleep-inducing effect.

[0035] 2. The special combination of rosemary extract, grape seed extract and bergamot peel can enrich the aroma of bergamot oil, making the overall aroma of daily chemical fragrance essential oil containing orange blossom more harmonious, giving users a better experience, thus helping to enhance the sleep-inducing effect.

[0036] 3. The present application prepares bergamot oil by a special extraction method in which a rosemary extract, a grape seed extract, and a calcium hydroxide aqueous solution are prepared into an immersion solution and combined with bergamot peel. The bergamot oil can effectively inhibit the oxidation reaction of the bergamot oil and protect the aroma factors of the bergamot oil, thereby improving the overall tolerance of the daily chemical essential oil containing orange blossom to high temperature, light, and humidity, prolonging its action time and ensuring its quality.

[0096] Performance testing

[0097] Test 1:

[0098] 100 volunteers aged 30-35 were selected and randomly divided into 12 groups, with 10 people in each group, one group corresponding to a daily chemical fragrance essential oil containing orange blossom in Examples 1-9 and Comparative Example 1.

[0099] Take 1 mL of the daily chemical fragrance oil containing orange blossom of Examples 1-9 and Comparative Example 1, drop it on paper, and place it at the head of the volunteer's bed. The volunteer lies flat on the bed naturally, can smell the daily chemical fragrance oil lightly, and falls asleep naturally. The corresponding daily chemical fragrance oil is tried for 7 consecutive days to help sleep.

[0100] Questionnaires were distributed to volunteers, and they were asked to rate their sleep-aiding effects on a scale of 0-10. The closer the score was to 10, the more significant the sleep-aiding effect was. The average score of the volunteers in the same group was taken as the result of the group and recorded in Table 2.

[0101] Test 2:

[0102] 30 healthy volunteers with normal sense of smell and aged 25-35 were selected to evaluate the daily chemical fragrance essential oil containing orange blossom of Examples 1-9 and Comparative Example 1 using the method of inducing air into the nose. Based on a score of 0-10, the fragrance harmony, fragrance richness and overall fragrance of the daily chemical fragrance essential oil containing orange blossom were scored. The closer to 10 points, the better the fragrance harmony / fragrance richness / aroma overall effect. The average score of the volunteers was the result of the group, which is recorded in Table 2.

[0103] Table 2

[0104]

[0105] According to the test data in Table 2, the daily chemical fragrance essential oil containing orange blossom in Examples 1-9 has better performance in terms of sleep-aiding effect and fragrance than that in Comparative Example 1. This indicates that the product prepared by combining orange blossom essential oil, tangerine oil, and bitter orange essential oil in a specific amount in the system has a good sleep-aiding effect and a pleasant and harmonious fragrance.

[0106] Further, Examples 4-9 are based on Example 1, but the raw materials or preparation methods of bergamot oil are changed, and the performance and aroma of the obtained bergamot oil are changed, so that the overall raw materials of the product cannot be fully matched, thereby reducing the product performance. It shows that when ensuring the selection and dosage of orange blossom essential oil, tangerine oil, and bitter orange essential oil, if a specific bergamot oil can be further preferred, the performance of the obtained product can be better improved.

[0107] Test 3:

[0108] The daily chemical fragrance essential oils containing orange blossom of Examples 1-9 and Comparative Example 1 were filled into transparent glass bottles and placed in an ultraviolet radiation box (450 W / m 2 , 45°C, humidity 70%), leave it open for 2 weeks, take it out and observe whether its morphology and color have changed, and record the results in Table 3.

[0109] Thirty healthy volunteers aged 25-35 with normal sense of smell were selected to evaluate the daily chemical fragrance oil containing orange blossom after extraction using the method of inhaling air into the nose to compare whether the smell of the daily chemical fragrance oil containing orange blossom after extraction has changed compared with the untreated daily chemical fragrance oil containing orange blossom. The number of volunteers who thought that "there was a change" was recorded in Table 3.

[0110] Table 3

[0111]

[0112]

[0113] According to the test data in Table 3, although Comparative Example 1 uses the same bergamot oil as Example 1, Comparative Example 1 greatly changes the dosage of orange blossom essential oil, tangerine oil, and bitter orange essential oil, so the specially prepared bergamot oil cannot fully exert its effect, resulting in unstable storage performance of the product under high humidity, high temperature, and light conditions. Therefore, the specially prepared bergamot oil can give full play to its good stability in a specific system and improve the overall performance of the product.

[0114] Example 4 is based on Example 1, and the dosage relationship of rosemary extract and grape seed extract is changed; Example 5-6 is based on Example 1, and any of rosemary extract and grape seed extract is replaced with other raw materials; Example 7 is based on Example 1, and rosemary extract and grape seed extract are omitted at the same time. According to the comparison of the test data of Example 1 and Examples 4-7 in Table 3, it can be seen that the product performance of Examples 4-7 is not as stable as that of Example 1; different degrees of damage to specific combinations also bring different degrees of influence. It is necessary to limit the combination of rosemary extract, grape seed extract and bergamot peel under specific conditions to prepare a special bergamot oil, which can be applied to the product to have good stability and harmonious and rich aroma, so as to maintain the good performance of the product for a longer period of time and give full play to the sleep-aiding effect.

[0115] According to the comparison of the detection data of Examples 8-9 and Example 1 in Table 3, it can be seen that further limiting the microwave power can make the bergamot peel and the mixed solution more fully mixed, thereby improving the product storage, sleep-aiding and other effects.

[0116] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
