Abstract
Description
Technical Field
[0001] This application relates to the field of soap technology, and more specifically, to a soap made from vine tea essential oil based on high-frequency extraction of vine tea extract and its preparation method. Background Technology
[0002] Washing and conditioning soaps are a type of solid soap product that combines cleansing and conditioning functions. They are mainly made of fatty acid salts as the core cleansing ingredient through saponification and are widely used for the cleansing and conditioning of human skin, hair, and certain fabrics. Their core characteristics are reflected in three aspects: First, in terms of composition, in addition to basic cleansing ingredients, moisturizers, plant extracts, vitamins, and other conditioning ingredients are often added to reduce skin dryness while cleaning dirt and oil. Second, in terms of application scenarios, they can be further divided into facial soaps, bath soaps, shampoo soaps, and underwear soaps to suit the cleaning needs of different parts or items. Third, in terms of usage characteristics, they are usually rich in foam and easy to rinse. Some products are formulated for different skin types such as sensitive skin and oily skin to balance cleansing power and gentleness.
[0003] Related soaps enhance their functional diversity by adding conventional plant extracts or essential oils. However, the extraction process often results in a significant loss of heat-sensitive active ingredients due to high temperatures or prolonged processing. Furthermore, the simple physical mixing of various functional ingredients makes it difficult to produce an effective synergistic effect. Inaccurate control of the alkali ratio can easily lead to incomplete or excessive saponification, resulting in insufficient content of active ingredients, poor overall care effect, and decreased stability. Summary of the Invention
[0004] To address the issues of insufficient active ingredient content, poor overall care effect, and decreased stability in related shampoo and body soaps due to the addition of conventional plant extracts or essential oils, this application provides a vine tea essential oil shampoo and body soap based on high-frequency extraction of vine tea extract and its preparation method.
[0005] In the first aspect, this application provides a vine tea essential oil shampoo and conditioner soap based on high-frequency extraction of vine tea extract, employing the following technical solution: A vine tea essential oil shampoo and conditioner soap based on high-frequency extraction of vine tea extract is made from the following raw materials in parts by weight: 40-60 parts vine tea extract; 40-60 parts sodium hydroxide; 4-6 parts vine tea essential oil; 1-4 parts psoralea essential oil; 1-4 parts Cnidium monnieri essential oil; 1-4 parts Dictamnus dasycarpus essential oil; 20-30 parts green tea seed and green fruit small molecule oil; 4-9 parts mango kernel small molecule oil; 2-6 parts palm oil; and 8-12 parts coconut small molecule oil.
[0006] By adopting the above technical solution, the formula system of this soap uses vine tea extract obtained by high-frequency extraction as the aqueous matrix. The active flavonoids contained therein undergo a saponification reaction with sodium hydroxide to form a cleansing base. The compound combination of vine tea essential oil, psoralea essential oil, Cnidium monnieri essential oil, and Dictamnus dasycarpus essential oil works synergistically to exert soothing and cleansing effects. At the same time, a high proportion of unsaponifiable matter such as green tea seed and green fruit small molecule oil and mango kernel small molecule oil are retained in the soap as natural moisturizing ingredients. Palm oil and coconut small molecule oil provide foaming properties and hardness, thus providing a solid soap product with cleansing, nourishing, and soothing functions.
[0007] Preferably, the weight ratio of the vine tea extract to sodium hydroxide is 1:1.
[0008] By adopting the above technical solution, controlling the concentration of alkali solution can ensure complete saponification. The 1:1 weight ratio allows sodium hydroxide to fully react with the acidic components in the oil and vine tea extract, thereby avoiding the presence of free alkali in the finished product that could cause skin irritation, and also preventing incomplete saponification from affecting product quality.
[0009] Preferably, the amount of vine tea essential oil added accounts for 3% of the total weight of the soap.
[0010] By adopting the above technical solution, the amount added is determined based on the concentration of the main active ingredients in vine tea essential oil and their utilization rate in the washing and care process. This ensures that the soap can release sufficient active substances through foam during use to achieve its expected soothing and fragrance effects, while avoiding excessive addition that could lead to high costs or affect the stability of the soap structure.
[0011] Preferably, the sum of the amounts of Psoralea corylifolia essential oil and Cnidium monnieri essential oil accounts for 5% of the total weight of the soap.
[0012] By adopting the above technical solution, the two essential oils in this ratio can achieve synergistic and complementary effects. The total amount is designed to ensure that the functional ingredients can be effectively released through soap hydrolysis each time they are used, thereby achieving the purpose of auxiliary maintenance in the cleaning process. This total amount control also avoids excessive essential oil components from interfering with the saponification reaction process and the hardness of the final product.
[0013] Preferably, the sum of the amounts of green tea seed and green fruit small molecule oil and mango kernel small molecule oil accounts for 65% of the total weight of the soap.
[0014] By adopting the above technical solution, the high addition ratio of these two small molecule oils as the main unsaponifiable oils determines the basic skin feel and moisturizing performance of the soap. They mainly exist as super fat agents in the soap body, which can form a moisturizing film after cleansing to reduce the tightness caused by the soap base. This dosage range ensures the balance between the cleansing effect and the product form.
[0015] Preferably, the sum of the added palm oil and coconut small molecule oil accounts for 26% of the total weight of the soap.
[0016] By adopting the above technical solution, palm oil provides hardness and durability to the soap body, while coconut small molecule oil is responsible for providing foaming properties to the product. The two work together in this ratio to ensure that the soap has good formability, foaming properties and durability, thereby maintaining the stability of the product's physical properties.
[0017] Secondly, this application provides a method for preparing a vine tea essential oil shampoo and conditioner soap based on high-frequency extraction of vine tea extract, using the following technical solution: A method for preparing a vine tea essential oil shampoo and conditioner soap based on high-frequency extraction of vine tea extract includes the following steps: S1. Preparation of vine tea extract: Take fresh vine tea, use a high-frequency extraction device, and extract for 75-115 minutes. Then, condense the cell sap from 55-65℃ to 19-30℃ through a condensation pipe under the action of a compressor to obtain vine tea extract. S2, Alkali Solution Preparation: The vine tea extract obtained in S1 is pre-frozen into ice cubes, then mixed with sodium hydroxide at a weight ratio of 1:1, and then cooled to below 44°C to obtain the alkali solution. S3, Oil Phase Mixing and Saponification: Add a portion of vine tea essential oil, psoralea essential oil, cnidium monnieri essential oil, dictamnus dasycarpus essential oil, green tea seed and green fruit small molecule oil, mango kernel small molecule oil, palm oil and coconut small molecule oil to the alkaline solution obtained in S2 in sequence, and control the soap solution temperature and stir in stages during the addition process until the soap solution is silky. S4. Defoaming and molding: Add the remaining vine tea essential oil to the silky soap liquid obtained in S3, and then perform vacuum defoaming treatment. After the soap liquid is free of bubbles, pour it into the mold, let it stand for 24 hours, then demold and divide it into blocks to obtain the vine tea essential oil soap.
[0018] By adopting the above technical solution, this preparation method controls the conditions and process of the saponification reaction through step-by-step operation. The high-frequency extraction process first retains the heat-sensitive active substances in the vine tea; freezing the original liquid and mixing it with alkali can control the exothermic rate in the early stage of the reaction, thereby avoiding local overheating that could lead to component deactivation; then, oils are added in stages and the temperature of each stage is controlled to ensure that oils with different melting points and reactivity can participate in saponification evenly; the final vacuum degassing treatment removes the gas introduced during the stirring process, avoiding the formation of pores in the finished product that would affect product quality and service life, thus ensuring the functionality and stability of the final product.
[0019] Preferably, the soap is added in the following order: first, vine tea essential oil and psoralea essential oil are added and stirred for 3 hours; second, cnidium monnieri essential oil is added and stirred for 2 hours; third, dictamnus dasycarpus essential oil is added; fourth, green tea seed and green plum small molecule oil is added and stirred for 2 hours; fifth, mango kernel small molecule oil is added and stirred for 20 minutes; sixth, palm oil is added and stirred for 1 hour; and seventh, coconut small molecule oil is added and stirred for 1 hour. The temperature of the soap solution is controlled below 17℃ for the first four additions and below 22℃ for the last three additions.
[0020] By adopting the above technical solution, the staged addition and stirring are based on the chemical characteristics and saponification reaction of different raw materials. In the early stage, adding essential oil components at low temperature helps them to be better dispersed in the lye solution and reduce volatilization loss. Subsequently, adding the main functional oils while maintaining a low temperature can protect their active ingredients. In the later stage, appropriately increasing the temperature and adding foaming oils can promote more complete saponification to optimize foam quality. The stirring time of each stage ensures that the batch of raw materials can be fully emulsified and reacted, thereby obtaining a soap solution with a uniform and silky texture.
[0021] Preferably, in step S4, the parameters for vacuum degassing are: the evacuation time is set to within 15 minutes, and the pressure holding time is set to 20 minutes.
[0022] By adopting the above technical solution, the brief evacuation time is sufficient to remove most of the visible bubbles, while the subsequent pressure holding stage, combined with intermittent evacuation, allows the tiny bubbles inside the viscous soap solution enough time to slowly escape and break. This combination of time ensures the defoaming effect.
[0023] Preferably, in step S4, the weight of the vine tea essential oil added again is 66% of the total weight of the vine tea essential oil.
[0024] By adopting the above technical solution, this post-addition process can ensure the preservation of fragrance and activity. Most of the vine tea essential oil is added after the main saponification reaction is completed and before pouring into the mold. This can minimize the volatilization or chemical structure damage of the essential oil in a long-term strong alkaline environment and during stirring. This ensures that more complete and effective essential oil components can be retained in the final product and released with water during use, thereby improving the user experience and functionality of the product.
[0025] In summary, this application has the following beneficial effects: 1. This application uses a high-frequency extraction process to obtain vine tea extract as the aqueous phase, and combines it with a specific ratio of vine tea essential oil, psoralea essential oil, Cnidium monnieri essential oil and Dictamnus dasycarpus essential oil. Since high-frequency extraction can efficiently break the cell walls and condense and preserve the heat-sensitive flavonoid active substances in the vine tea cell fluid under low temperature conditions, the synergistic effect of the four essential oils enhances the soothing and cleansing efficacy of the product. At the same time, by controlling the ratio of sodium hydroxide to vine tea extract, the completeness of the saponification reaction is ensured. Thus, a solid washing and care product with high cleansing power, maintenance effect and good stability is obtained.
[0026] 2. In this application, a preparation process of adding oils in stages and controlling the temperature is preferred. Since this process is based on the chemical properties and reactivity of different oils, the first four additions are carried out at a temperature below 17°C to protect the volatility of essential oil components and the activity of unsaponifiable oils, while the last three additions are carried out at a temperature below 22°C to promote the full saponification of foaming oils. The stirring time of each stage is set according to the emulsification and reaction requirements of the materials, thus obtaining a soap solution with a uniform and silky texture and a high retention rate of various functional components.
[0027] 3. The method of this application adds vine tea essential oil again after the main saponification reaction is completed and uses vacuum degassing. Because the vine tea essential oil is added in stages, it avoids the damage to the active ingredients of the essential oil caused by strong alkaline environment and long-term stirring. The combination of degassing parameters can not only efficiently remove visible large bubbles, but also provide time for the escape of deep micro bubbles, thereby improving the retention rate of functional ingredients in the finished product, while ensuring that the internal structure of the product is dense and defect-free.

[0054] Table 1 shows the test values of the performance parameters of Examples 1-3 and Comparative Examples 1-6.
[0055] Table 1: Group Total flavonoid content (mg / g) Cleanliness rate (%) 4-hour hydration rate (%) Inflammatory factor inhibition rate (%) Stability change rate (%) Example 1 35.2 92.5 68.3 63.7 5.2 Example 2 38.6 93.1 69.8 65.2 4.8 Example 3 36.9 92.8 69.1 64.5 5.0 Comparative Example 1 18.7 85.6 52.4 45.3 12.6 Comparative Example 2 22.3 79.8 48.7 42.1 18.9 Comparative Example 3 26.4 87.2 56.3 48.9 9.8 Comparative Example 4 29.1 86.5 54.7 46.2 8.7 Comparative Example 5 20.5 84.3 50.2 43.7 14.3 Comparative Example 6 28.3 88.1 57.6 49.5 10.2 Example Conclusion: Based on Examples 1-3 and Comparative Example 1, and in conjunction with Table 1, it can be seen that the amount of vine tea extract used is sufficient to ensure that the content of active flavonoids in the product is adequate. When the amount of extract used is insufficient, not only does the total flavonoid content decrease, but the product's cleaning efficacy and moisturizing durability are also affected. This demonstrates the supporting role of vine tea extract as an aqueous matrix in the basic performance of the product.
[0056] Based on Examples 1-3 and Comparative Example 2, and in conjunction with Table 1, it can be seen that maintaining a 1:1 ratio of sodium hydroxide to vine tea extract ensures complete saponification. Excessive alkali not only damages the active ingredients and reduces the soothing effect, but also deteriorates product stability. This confirms the necessity of controlling the concentration of alkali solution to maintain product safety and stability.
[0057] Based on Examples 1-3 and Comparative Example 3, and in conjunction with Table 1, it can be seen that the appropriate addition of vine tea essential oil can enhance the overall efficacy of the product. When the amount of essential oil is insufficient, the anti-inflammatory and soothing properties of the product are weakened, and the cleansing and moisturizing effects are also reduced. This indicates that vine tea essential oil plays a functional synergistic role in the compound system.
[0058] Based on Examples 1-3 and Comparative Example 4, and in conjunction with Table 1, it can be seen that the appropriate ratio of Psoralea corylifolia essential oil is an influencing factor in achieving synergistic effects of multiple essential oils. When its dosage is too low, it will lead to an imbalance in the overall efficacy system.
[0059] As can be seen from Examples 1-3 and Comparative Example 5, and Table 1, high-frequency extraction time can ensure a high extraction rate of active ingredients in vine tea. Insufficient extraction time will lead to a decrease in the content of active ingredients in the original solution, which will affect the various performance indicators of the final product. This confirms that the complete extraction process can ensure a high retention of natural active ingredients in vine tea.
[0060] Based on Examples 1-3 and Comparative Example 6, and in conjunction with Table 1, it can be seen that the process of adding a high proportion of vine tea essential oil in step S4 can improve the retention rate of active ingredients. When the addition proportion is insufficient, it will reduce the content of functional ingredients in the product. This verifies that the post-addition process can protect the heat-sensitive active ingredients in the product.
[0061] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
