Description

Technical Field

[0001] This application belongs to the field of daily chemical product preparation technology, and in particular relates to a shower gel based on a high-purity extract of Artemisia argyi and its preparation method. Background Technology

[0002] With the fast pace of modern life and increasing work pressure, sub-health conditions are becoming increasingly common. People's demand for bath products has transcended simple cleaning functions, shifting towards a pursuit of higher-level emotional and health benefits. The rise of aromatherapy is a concentrated manifestation of this demand. Incorporating natural plant extracts with soothing and fatigue-relieving effects into daily bath products, making the bathing process an immersive sensory experience and a healing ritual for body and mind, has become an important development trend in the personal care products industry.

[0003] Traditional Chinese medicine believes that mugwort has the effects of warming the meridians and dispelling cold, removing dampness and relieving pain, reducing inflammation, relieving asthma, stopping cough, calming the fetus, and anti-allergy. Modern medical research has found that mugwort leaves have antibacterial and antioxidant functions. High-purity mugwort extract, as a high-purity extract of mugwort, is an oily liquid at room temperature, almost insoluble in water, easily soluble in organic solvents, and has poor storage stability. It is sensitive to environmental conditions such as light, temperature, and air, and is prone to degradation, which is not conducive to storage and processing, greatly limiting its practical application. Microemulsions also have advantages such as low viscosity, strong solubilizing ability, simple preparation, spontaneous formation, and good long-term storage stability. They can improve the water solubility of high-purity mugwort extract to a certain extent and enhance its stability in daily chemical products.

[0004] Patent application CN109646351A discloses a mugwort-infused refreshing and dehumidifying shower gel and its preparation method. This technology uses a specific compound surfactant and mugwort extract, with a clear formula and simple preparation steps, achieving refreshing and dehumidifying effects, cleansing and skin care, and is easy to operate for industrial production. However, this technology uses low-temperature extraction with hydrochloric acid and methanol, which poses certain safety risks and can easily destroy the effective components of mugwort. In addition, patent CN111956558A discloses a mugwort extract, its preparation method, and its applications. This technology uses a composite extraction process of supercritical CO2 extraction of volatile oils and water extraction of medicinal residue, resulting in a more complete range of effective mugwort components, outstanding antibacterial effects, and a mild, low-irritant preparation suitable for various daily chemical products such as shower gels and soaps. However, this technology requires advanced extraction equipment, is costly, has a more complex process, and is difficult to industrialize. Summary of the Invention

[0005] To address the aforementioned issues and further improve the long-term stability and uniform dispersibility of high-purity Artemisia argyi extract and its synergistic essential oils in water-based shower gel systems, this application provides a shower gel based on high-purity Artemisia argyi extract and its preparation method.

[0006] This application first provides a shower gel based on a high-purity extract of Artemisia argyi, comprising the following components in parts by weight: 60-75 parts deionized water, 0.05-0.1 parts disodium EDTA, 4-8 parts dodecyl alcohol polyoxyethylene ether sulfate, 10-15 parts cocamidopropyl betaine, 5-8 parts PEG-80 sorbitan laurate, 3-6 parts glycerin, 2-4 parts DOE-120 thickener, 4-8 parts Artemisia argyi high-purity extract nanoemulsion, and 0.2-0.5 parts phenoxyethanol.

[0007] Furthermore, the high-purity Artemisia argyi extract nanoemulsion comprises the following components in parts by weight: 20-30 parts of compound surfactant, 25-35 parts of compound co-surfactant, 25-35 parts of high-purity Artemisia argyi extract, 3-8 parts of lavender essential oil, 3-8 parts of sweet orange essential oil, 2-5 parts of squalane, and 10-20 parts of deionized water.

[0008] Furthermore, the preparation method of the high-purity Artemisia argyi extract is described in accordance with the application document with publication number CN118648689A.

[0009] Furthermore, the preparation method of the high-purity Artemisia argyi extract nanoemulsion includes the following steps: Mix all components of the compound surfactant evenly; mix all components of the composite co-surfactant evenly; mix the composite co-surfactant with the compound surfactant, heat and stir, then slowly add the high-purity extract of Artemisia argyi, lavender essential oil, sweet orange essential oil and squalane and continue stirring; cool down and add deionized water and continue stirring to obtain the final product.

[0010] Furthermore, the compound surfactant is prepared from sucrose stearate, Tween-80 and decyl glucoside in a mass ratio of (4-6):(3-5):(2-4).

[0011] Furthermore, the composite co-surfactant is prepared from anhydrous ethanol, glycerol and 1,2-propanediol in a mass ratio of (2-4):(5-7):(1-3).

[0012] This application also provides a method for preparing a shower gel based on a high-purity extract of Artemisia argyi, comprising the following steps: Heat deionized water, add disodium EDTA and stir until homogeneous; add dodecyl alcohol polyoxyethylene ether sulfate, cocamidopropyl betaine, and PEG-80 sorbitan laurate, and stir until completely dissolved; add glycerin and stir, then cool and add DOE-120 thickener and stir; cool and add Artemisia argyi high-purity extract nanoemulsion and phenoxyethanol and continue stirring; add citric acid to adjust pH, let stand to defoam, and the product is ready.

[0013] Furthermore, the temperature at which the deionized water is heated is 65-75℃.

[0014] Furthermore, citric acid is added to adjust the pH to 5.5-6.5.

[0015] Furthermore, the stirring time after adding the high-purity Artemisia argyi extract nanoemulsion and phenoxyethanol is 3-8 minutes.

[0016] Furthermore, the settling and defoaming time is 6-10 hours.

[0017] Compared with the prior art, this application has the following beneficial effects: 1. The high-purity Artemisia argyi extract nanoemulsion prepared in this application utilizes the synergistic effect of compound surfactants and composite co-surfactants to significantly improve the dispersion stability of the high-purity Artemisia argyi extract, enabling it to be evenly distributed in the shower gel system and fully exert its efficacy. The constructed ternary compound surfactant system of sucrose stearate, Tween-80, and decyl glucoside provides mechanical strength to the interfacial film through the rigid structure of sucrose stearate, provides steric hindrance through the long-chain structure of Tween-80, and provides hydration layer protection through the glycosyl head group of decyl glucoside. The synergistic effect of these three components can simultaneously meet the solubilization requirements of essential oils with different molecular structures, achieving uniform dispersion of the mixed essential oil system. In addition, the addition of lavender essential oil and sweet orange essential oil not only enriches the aroma experience of the product but also has a synergistic effect with the high-purity Artemisia argyi extract, further enhancing the product's nerve-soothing and fatigue-relieving effects.

[0018] 2. The shower gel prepared in this application, based on high-purity Artemisia argyi extract, contains a variety of natural antibacterial ingredients that can effectively inhibit the reproduction of common opportunistic pathogens such as Staphylococcus aureus and Escherichia coli. It has a significant killing and inhibitory effect on harmful microorganisms on the skin surface. While cleansing the skin, it can reduce skin problems caused by bacterial or fungal infections, such as folliculitis, back acne, and tinea versicolor, reduce the pathogenic bacterial load on the skin surface, and prevent odor. Compared with chemical antibacterial agents, the antibacterial ingredients derived from Artemisia argyi are gentler, do not disrupt the normal skin flora balance, and leave the skin feeling refreshed and comfortable after washing. Long-term use helps build a healthy skin microecological environment and enhances the skin's own defense capabilities.

[0019] 3. The shower gel prepared in this application, based on high-purity Artemisia argyi extract, is rich in various natural antioxidant active ingredients. These ingredients can effectively remove excess free radicals and block the attack of oxidative stress on skin cells. During bathing, the antioxidant active ingredients can adhere to the skin surface, forming a temporary protective film that continuously exerts its antioxidant effect. This reduces the stimulation of the skin by environmental factors during bathing, helps maintain the integrity of the skin barrier, improves skin elasticity and radiance, delays the skin aging process, and keeps the skin youthful and healthy. Furthermore, it can lay a good foundation for applying serums, body lotions, and other skincare products after bathing, jointly building a more comprehensive antioxidant defense system.

[0044] Performance testing 1. Sensory index tests were conducted on the shower gels based on high-purity Artemisia argyi extract prepared in Examples 1-3 and Control Groups 1-2 in accordance with the standard QB / T1994-2013 Shower Gel. The test results are shown in Table 1.

[0045] 2. The antibacterial properties of the shower gels based on high-purity Artemisia argyi extract prepared in Examples 1-3 and Control Groups 1-2 were tested according to the "Hygienic Standard for Disposable Sanitary Products GB15979-2024". The test temperature was 22±1℃ and the action time was 10 minutes. The test strains were Escherichia coli 8099, Staphylococcus aureus ATCC6538 and Candida albicans ATCC100231. The test results are shown in Table 2.

[0046] 3. The antioxidant activity of the shower gels based on high-purity Artemisia argyi extract prepared in Examples 1-3 and Control Groups 1-2 was tested using the DPPH method. The test results are shown in Table 3.

[0047] Table 1. Sensory index test results of the shower gel Table 2 Results of the antibacterial performance test of the shower gel Table 3. Results of antioxidant activity test of the shower gel Analysis of Examples 1-3 and Control Groups 1-2, combined with the test data in Tables 1-3, shows that the shower gel based on high-purity Artemisia argyi extract prepared in this application exhibits excellent performance in terms of sensory properties, antibacterial properties, and antioxidant activity. It successfully achieves the core objective of stably dispersing high-purity Artemisia argyi extract and other functional essential oils in the form of a nanoemulsion within an aqueous shower gel system. The product has a uniform and stable appearance, a characteristic Artemisia argyi fragrance, and enhanced functionality and gentleness. Compared to Examples 1-3, Control Group 1, in preparing the Artemisia argyi extract nanoemulsion, did not use the surfactant system composed of sucrose stearate, Tween-80, and decyl glucoside as defined in the claims of this application, nor the co-surfactant system composed of anhydrous ethanol, glycerol, and 1,2-propanediol. Instead, it only used Tween-80 as the surfactant and glycerol as the co-surfactant. From the test results, firstly, in terms of antibacterial performance, the kill rate of Escherichia coli, Staphylococcus aureus, and Candida albicans in Control Group 1 was generally lower than that in the Example Group. For example, its kill rate against Escherichia coli (56.89%) was significantly lower than that of Example 1 (62.48%) and Example 3 (62.57%); its kill rate against Candida albicans (57.55%) was also significantly lower than that of the examples (62.55%-64.98%). Secondly, in terms of antioxidant activity, the DPPH free radical scavenging rate of Control Group 1 was also slightly lower than that of Examples 1-3. This is mainly because a single surfactant and co-surfactant system is difficult to form a stable and dense interfacial film like a compound system, resulting in insufficient stability, particle size uniformity, or encapsulation efficiency of essential oil active ingredients in the prepared nanoemulsion, thus affecting the effective retention and slow release of essential oil functional ingredients in the final product, causing some antibacterial and antioxidant activities to be lost during storage or testing. Compared with Examples 1-3, Control Group 2 did not add Artemisia argyi high-purity extract nanoemulsion, that is, it completely lacked the effective components such as Artemisia argyi, lavender, sweet orange essential oil, and squalane. The performance degradation was most significant: in terms of antibacterial performance, the kill rate of the three test bacteria in control group 2 was far lower than that in examples 1-3, especially consistent with the expectation of not containing any essential oil components. Its antibacterial power mainly relied on the basic cleansing formula, with weak efficacy. In terms of antioxidant activity, its DPPH scavenging rate was only 12.54%, a huge difference from the example group. This directly and strongly proves that the significant antibacterial and antioxidant effects exhibited by the shower gel based on high-purity Artemisia argyi extract prepared in this application are due to the added high-purity Artemisia argyi extract nanoemulsion. Nanoemulsion technology effectively protects and delivers the active substances in essential oils such as Artemisia argyi, allowing them to fully play their role in the shower gel system. The nanoemulsion carrier system constructed from specific compound surfactants and composite co-surfactants used in this application is crucial. It is not only the key technology for achieving long-term stable dispersion of essential oils in aqueous systems, but also the core means to ensure and enhance the product's core efficacy such as antibacterial and antioxidant properties.The results of control group 1 verified the superiority of the compound emulsification system, while the results of control group 2 confirmed the core contribution of functional components such as the high-purity extract of Artemisia argyi.

[0048] In summary, the innovation of this application lies in its ingenious solution to the industry challenge of poor solubility, instability, and easy degradation of high-purity Artemisia argyi extract in water-based daily chemical products through an optimized nanoemulsion construction technology. This technology not only enables the product to achieve excellent stability and sensory properties, but more importantly, it maximizes the preservation and utilization of the active effects of natural Artemisia argyi and its compound essential oils. This upgrades the shower gel from a simple cleansing product into an innovative product with cleansing, skin care (antioxidant), and health support (antibacterial) functions, demonstrating significant substantive features and substantial progress compared to existing technologies.

[0049] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
