Description

Technical Field

[0001] This invention relates to the field of essential oil technology for treating inflammation, and in particular to a compound essential oil that effectively relieves vaginal inflammation and its preparation method. Background Technology

[0002] Vaginal inflammation is a common disease of the female reproductive system, mainly including bacterial vaginosis, fungal vaginitis (candidiasis), and trichomonal vaginitis. Its pathogenesis is closely related to factors such as vaginal microecological imbalance, the proliferation of harmful microorganisms, damage to the mucosal barrier, and decreased local immune function. At present, clinical treatment mainly uses chemical drugs such as antibiotics and antifungal drugs (such as metronidazole and clotrimazole). Although these drugs can quickly inhibit pathogens, long-term use can easily lead to vaginal flora resistance, disrupt the normal vaginal microecological balance, and some drugs are irritating, which may aggravate discomfort such as dry mucosa and itching. In addition, the recurrence rate of inflammation after discontinuation of drugs is high, and it is difficult to fundamentally repair the mucosal barrier and improve local resistance.

[0003] In the field of assisted care products, existing plant essential oil products are mostly based on single essential oils or simple blends, which have the following shortcomings: First, the ingredients are singular, mostly focusing only on antibacterial functions, lacking synergistic design for mucosal barrier repair and microecological regulation. Second, some products contain irritating ingredients (such as high-concentration undiluted essential oils), making them unsuitable for sensitive vaginal mucosa. Third, the manufacturing process is simple, without optimization for the solubility and stability of the oil phase components, easily leading to problems such as layering and active ingredient deactivation. Fourth, there is a lack of design adapted to the vaginal physiological environment (slightly acidic pH, mucosal fragility), making it difficult to balance safety and effectiveness.

[0004] Therefore, developing a compound essential oil that combines antibacterial and anti-inflammatory properties, mucosal repair, and microecological regulation, while being mild, highly stable, and compatible with the vaginal physiological environment, has become a key need to address the pain points of existing treatment and care products. Summary of the Invention

[0005] The purpose of this invention is to provide a compound essential oil that effectively relieves vaginal inflammation and its preparation method. Through the synergistic effect of plant essential oils, Chinese herbal extracts, and functional oils, it can inhibit harmful microorganisms, repair the mucosal barrier, regulate the vaginal microecology, and avoid the problems of flora imbalance and recurrence caused by simple drug treatment.

[0006] To achieve the above objectives, the present invention provides a compound essential oil that effectively relieves vaginal inflammation, comprising the following components by weight: 30-60 parts of compound plant essential oil, 10-40 parts of sea buckthorn fruit oil, 1-5 parts of α-glucan oligosaccharide, and 0.1-10 parts of adjuvants.

[0007] Preferably, the compound plant essential oils include antibacterial essential oils and soothing essential oils, with a mass ratio of 6-9:1-4.

[0008] Preferably, the antibacterial essential oil includes at least one of the following: tea tree oil, neem oil, and ash oil. Soothing essential oils include at least three of the following: tuberose, sandalwood, ylang-ylang, vetiver, Rosa damascena, and magnolia.

[0009] Preferably, the adjuvants include one or more of vitamin E oil, black cumin seed oil, and shea butter.

[0010] A method for preparing a compound essential oil that effectively relieves vaginal inflammation includes the following steps: S1. Weigh out 30-60 parts of compound plant essential oil, 10-40 parts of sea buckthorn fruit oil, 1-5 parts of α-glucan oligosaccharide and 0.1-10 parts of auxiliary agent according to the following weight proportions; S2. Mix the compound plant essential oil and sea buckthorn fruit oil, and stir until a homogeneous mixed oil phase is obtained; S3. Add α-glucan oligosaccharide to the mixed oil phase obtained in S2 and stir until completely dispersed. Then add the additives and continue stirring to obtain a mixed system. S4. Transfer the mixture obtained in S3 to a sealed container, adjust the pH to 4-4.5, let it stand and age at room temperature in the dark, and filter to obtain the compound essential oil. S5. Place the compound essential oil obtained in S4 into a sterilized brown glass bottle, seal it, and store it away from light.

[0011] Preferably, in S2, the mass ratio of the compound plant essential oil and sea buckthorn fruit oil is 1-6:1.

[0012] Preferably, in S2, the stirring speed is 300-500 r / min and the stirring time is 5-25 min.

[0013] Preferably, in step S3, when the added adjuvant includes shea butter, the mixture is heated and stirred at 45-50°C after adding the adjuvant, and homogenized to obtain a mixed system.

[0014] Preferably, in step S3, the stirring speed is 300-500 r / min and the stirring time is 0.1-1 h.

[0015] Preferably, in step S4, the settling time is 24-72 hours, and the material is filtered through a 200-300 mesh filter.

[0016] Therefore, the present invention employs the above-mentioned compound essential oil for effectively relieving vaginal inflammation and its preparation method, the beneficial effects of which are: 1. The compound essential oil provided by this invention, through the synergistic effect of plant essential oils and functional oils, can inhibit harmful microorganisms, repair the mucosal barrier, and regulate the vaginal microecology, thus avoiding the problems of flora imbalance and recurrence caused by simple drug treatment. 2. The compound essential oil provided by this invention consists of low-irritant and highly compatible substances, with no risk of chemical drug resistance, which can reduce irritation to the vaginal mucosa and is suitable for long-term auxiliary care.

[0017] The technical solution of the present invention will be further described in detail below through embodiments. Detailed Implementation

[0018] The present invention will be further described below with reference to embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate the invention and are not intended to limit the scope of the invention.

[0019] This invention provides a compound essential oil for effectively relieving vaginal inflammation, comprising the following components by weight: 30-60 parts of compound plant essential oil, 10-40 parts of sea buckthorn fruit oil, 1-5 parts of α-glucan oligosaccharide, and 0.1-10 parts of adjuvants. The compound plant essential oil collectively inhibits pathogenic bacteria at different target sites. Simultaneously, α-glucan oligosaccharide, by regulating the microecology, inhibits the growth of harmful bacteria, providing auxiliary support for antibacterial and anti-inflammatory effects. Sea buckthorn fruit oil moisturizes the vaginal mucosa, repairs damaged mucosal tissue, enhances mucosal resistance, reduces inflammation recurrence, and relieves discomfort caused by dryness and damage to the mucosa. Its antioxidant effect can also reduce inflammatory responses and help improve inflammatory symptoms. As a prebiotic, α-glucan oligosaccharide can selectively promote the proliferation of beneficial bacteria (such as lactobacilli) in the vagina. Lactobacilli produce lactic acid, maintaining a slightly acidic environment in the vagina, which inhibits the growth of harmful bacteria. At the same time, lactobacilli can also produce antibacterial substances (such as bacteriocins), which further inhibit the reproduction of pathogenic bacteria and regulate the vaginal microecological balance.

[0020] In some embodiments of the present invention, the compound plant essential oil includes antibacterial essential oil and soothing essential oil, and the mass ratio of antibacterial essential oil to soothing essential oil is 6-9:1-4.

[0021] In some embodiments of the present invention, the antibacterial essential oil includes at least one of the following: *Tetracentron sinense* essential oil, tea tree essential oil, and neem essential oil. *Tetracentron sinense* essential oil contains eucalyptol, tea tree essential oil contains terpinene-4-ol, and neem essential oil contains azadirachtin. These three components, respectively, disrupt bacterial cell membranes, inhibit fungal ergosterol synthesis, and interfere with trichomonas metabolism, forming a broad-spectrum antibacterial system targeting bacteria, fungi, and trichomonas. Tea tree essential oil contains active ingredients such as terpinene-4-ol, which can penetrate microbial cell membranes, disrupting the integrity of the cell membrane structure, leading to leakage of microbial contents, and simultaneously interfering with microbial metabolic processes, inhibiting their growth and reproduction. The core component of neem essential oil, azadirachtin, can inhibit the activity of fungal cytochrome P450 enzyme systems, affecting the synthesis of ergosterol in the fungal cell membrane, leading to changes in cell membrane permeability, thereby inhibiting fungal growth; it also has a certain inhibitory effect on trichomonas, disrupting the cell structure and function of trichomonas.

[0022] Soothing essential oils include at least three of the following: tuberose, sandalwood, ylang-ylang, vetiver, Rosa damascena, and magnolia. The linalool in tuberose, the farnesol in ylang-ylang, and the gallic acid in Rosa damascena can neutralize the irritation of antibacterial essential oils, while also inhibiting the release of inflammatory factors and reducing mucosal redness and itching. Magnolia essential oil contains linalool, eugenol, and other components. Linalool can inhibit microbial growth, while eugenol has anti-inflammatory effects, inhibiting the release of inflammatory factors. Its aroma components can also soothe nerves and relieve anxiety caused by inflammatory discomfort.

[0023] In some embodiments of the present invention, the adjuvants include one or more of vitamin E oil, black cumin seed oil, and shea butter. Vitamin E oil protects the essential oil and other active ingredients from oxidative damage, maintaining their stability and activity. Shea butter can adjust the texture of the product, enhance moisturizing sensation, and repair mucous membranes, forming a thick protective film on the surface of the vaginal mucosa, effectively locking in moisture and reducing mucosal dryness. Black cumin seed oil contains thymequinone, nigerin, and other components. Thymequinone has antibacterial and anti-inflammatory effects, inhibiting the growth of pathogenic bacteria and reducing the release of inflammatory factors; nigerin can regulate the body's immune function, enhance local resistance, and promote mucosal cell regeneration.

[0024] A method for preparing a compound essential oil that effectively relieves vaginal inflammation includes the following steps: S1. Weigh out 30-60 parts of compound plant essential oil, 10-40 parts of sea buckthorn fruit oil, 1-5 parts of α-glucan oligosaccharide, and 0.1-10 parts of auxiliary agent according to the following mass proportions; S2. Mix the compound plant essential oil and sea buckthorn fruit oil, and stir until a homogeneous mixed oil phase is obtained; S3. Add α-glucan oligosaccharide to the mixed oil phase obtained in S2 and stir until completely dispersed. Then add the additives and continue stirring to obtain a mixed system. S4.

Place the compound essential oil obtained in S4 into a sterilized brown glass bottle, seal it, and store it away from light.

[0025] In some embodiments of the present invention, in step S2, the mass ratio of the compound plant essential oil and sea buckthorn fruit oil is 1-6:1. Based on the positioning of antibacterial as the main function and repair as a secondary function, the antibacterial activity of the compound essential oil and the moisturizing and repairing ability of the sea buckthorn fruit oil are balanced.

[0026] In some embodiments of the present invention, in step S2, the stirring speed is 300-500 r / min and the stirring time is 5-25 min.
