Description

Technical Field

[0001] The invention belongs to the technical field of ointment preparation, and particularly relates to a shower ointment containing ginger essential oil for warming meridians and dispelling cold, and a preparation method and application thereof. Background Art

[0002] With the rapid development of economy and science and technology, people's pace of life is accelerating, and life pressure and mental pressure are also increasing. The combination of physical factors and environmental factors will cause human body dysfunction, blood circulation disorders and other problems. When the weather turns cooler, it is easy to have problems with cold hands and feet. The cool weather causes the body to get cold, which will affect the liver's hematopoietic function, thereby leading to insufficient kidney yang.

[0003] Usually, mild blood circulation disorders are easily ignored, but cold hands and feet are one of the more obvious manifestations of blood circulation disorders. When cardiovascular circulation is impaired, blood transport will be affected, blood vessels will contract, blood flow will decrease, and blood supply to the extremities will be unable to reach them. Since hands and feet are the extremities of the limbs, cold hands and feet are prone to occur. If cold hands and feet occur frequently, it should be taken seriously, because severe blood circulation disorders may develop into various diseases, such as hyperlipidemia, arteriosclerosis, angina pectoris, etc.

[0004] There are many ways to relieve cold hands and feet, such as foot therapy, diet therapy, etc. However, with the improvement of people's quality of life, people's requirements for bathing are no longer limited to cleaning and cleansing the skin. They also need to have certain effects while bathing, such as aromatherapy and cold relief. Most of the shower heads on the market currently only provide people with a simple shower function. In today's rapidly developing world, a simple shower function can no longer meet people's needs. Bath balm is a product used with a shower head during bathing. It dissolves in water in the shower head and is sprayed on the user through the shower head, thereby achieving the effects of warming the meridians and dispelling cold.

[0005] For example, Chinese patent CN210614058U discloses a slow-release perfume stick for perfume atomizing nozzle, which can realize that the water spray head sprays out bath liquid with perfume, and the bath liquid sprayed by the water spray head has perfume, which makes people feel refreshed and comfortable, and bathing is cleaner.

[0006] Chinese patent CN116081792A discloses a shower filter element with moisturizing effect and its preparation method and application. The invention uses specific vitamins, plant extracts, collagen and essential oils as raw materials, and cooperates with a specific preparation process. The prepared shower filter element is used in the field of bathing. It can not only remove a large amount of chlorine in tap water, making the water that contacts the skin clean, gentle and non-irritating, but also has a certain moisturizing and antioxidant effect, can increase the water absorption and water locking function of the skin, keep the skin moisturized at all times, and increase the elasticity of the skin. The shower filter element prepared by the invention has high thermal stability and can be used at a temperature of 70°C. It can clean the skin during bathing and keep the skin from drying out. The raw materials are natural and mild, suitable for most people.

[0007] However, there is little research on bath ointments with the effect of warming meridians and dispelling cold in the existing technology, and it is necessary to develop a shower ointment containing ginger essential oil for warming meridians and dispelling cold, and a preparation method and application thereof.

[0084] Performance data:

[0085] 1. Antibacterial test

[0086] The Oxford cup punch method was used to analyze the antibacterial effects of the samples on Escherichia coli (ATCC8739), Staphylococcus aureus (ATCC6538), Malassezia furfur (ATCC44344) and Propionibacterium acnes (ATCC11827).

[0087] Take the activated E. coli and make a bacterial suspension with PBS at a concentration of 5×10 6 CFU / mL. Add bacteria and culture medium to the plate and mix thoroughly. Use tweezers to place a sterile Oxford cup on the surface of the culture medium and make a hole. After solidification, add 200 μg of the sample to be tested. Repeat 3 times for each sample. After culturing at 37℃±1℃ for 2 days, use a vernier caliper to measure the diameter of the inhibition zone. The diameter of the inhibition zone is used to evaluate the antibacterial effect. The operation steps for Escherichia coli are the same as those for Staphylococcus aureus. Propionibacterium acnes is cultured under anaerobic conditions at 37℃ for 2 days, and Malassezia furfur is cultured at 30℃ for 3 days.

[0088] The negative control sample (PBS) should not produce an antibacterial ring; the antibacterial ring diameter of the test sample is >7mm, which is considered to have an antibacterial effect; the antibacterial ring diameter is ≤7mm, which is considered to have no antibacterial effect. If all three parallel samples have an antibacterial effect, they are considered qualified. The antibacterial results are shown in Table 1.

[0089] Table 1

[0090]

[0091] According to the test results in Table 1 above, the bath balm of the present invention has a better antibacterial effect.

[0092] In Comparative Example 1-2, changing the thickener, emulsifier and sustained-release agent will affect the mixing of the plant extract and other components and the release of the active ingredients in the ointment, thereby significantly weakening the antibacterial effect.

[0093] In Comparative Example 3, only ginger root extract was added, and its antibacterial effect was not greatly affected, but it was quite irritating after use and the user experience was not good.

[0094] Changing the mass ratio of the plant extracts in Comparative Examples 4-5 will affect the antibacterial effect of the product and also affect the user experience.

[0095] 2. Human sensory evaluation

[0096] 70 volunteers were recruited and randomly divided into groups after enrollment. Each group consisted of 10 volunteers who used each group of shower gel for 4 weeks. The testers scored based on their experience. The scoring standard was 10 points, with 1 being the worst and 10 being the best. The higher the score, the better. The final results are shown in Table 2 below.

[0097] Table 2

[0098]

[0099] It can be concluded from the scoring results in Table 2 that the bath balm of the present invention is easy to rinse off after use, has a cold-dispelling effect after use, and is antibacterial and antipruritic, and is generally loved by testers.

[0100] In Comparative Example 1-2, changing the thickener, emulsifier and sustained-release agent will affect the mixing of the plant extract and other components and the release of the active ingredients in the ointment, thereby affecting the cold-dispelling effect and antibacterial effect after use, and the overall score of users is significantly reduced.

[0101] Changing the types of plant extracts in Comparative Examples 3-5 will affect the cold-dispelling and antibacterial effects of the products, and also affect the overall satisfaction of users.

[0102] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
