Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily chemical products, in particular to a hair nourishing and hair strengthening shampoo soap based on synergistic effect of multiple Chinese medicines and a preparation method thereof. BACKGROUND

[0002] With the acceleration of life pace, changes in environmental factors and the improvement of health awareness, hair health problems have increasingly attracted the attention of consumers. Hair nourishing and hair strengthening has become one of the core demands in the field of daily chemical washing and protection. People's demand for washing and protection products has gradually changed from pure cleaning to "mild nourishment and long-term care". Natural, safe and non-irritating washing and protection products have become the mainstream trend in the market. Hair nourishing and hair strengthening products with Chinese medicine as the core component are favored because they meet the traditional health concept of "same origin of medicine and food".

[0003] The existing hair nourishing and hair strengthening washing and protection products mainly use the method of adding chemical synthetic ingredients or simply compounding single Chinese medicine to realize the effects of cleaning, hair loss prevention and hair strengthening by using conventional extraction and molding processes. There are some defects. First, the extraction process is single and the raw material treatment is extensive, which leads to insufficient extraction of effective components and makes it difficult for the synergistic effect of multiple Chinese medicines to fully play. At the same time, the compatibility of Chinese medicine components and soap base is poor, and the product efficacy stability is poor. Second, the lack of efficient secondary extraction and fine molding and curing design not only wastes effective components of Chinese medicine, but also easily causes the soap body to contain air bubbles, uneven water distribution and cracking, and the release of efficacy components is not long-lasting. Therefore, we propose a hair nourishing and hair strengthening shampoo soap based on synergistic effect of multiple Chinese medicines and a preparation method thereof. SUMMARY

[0004] The purpose of the present application is to provide a hair nourishing and hair strengthening shampoo soap based on synergistic effect of multiple Chinese medicines and a preparation method thereof.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a preparation method of a hair nourishing and hair strengthening shampoo soap based on synergistic effect of multiple Chinese medicines, which comprises the following steps:

[0006] Step one, select genuine medicinal materials, classify and crush them according to the texture after three-stage screening, and then mix them uniformly to obtain a pretreated medicinal material mixture;

[0013] As a further scheme of the present application, in step one, the native medicinal materials are Sapindus from Yunnan, Radix Polygoni Multiflori from Sichuan, and Platycladus orientalis from Shandong, and the rest of the traditional Chinese medicines are Gleditsia sinensis, Ligustri Lucidi Fructus, Herba Tropaeoli, Folium Artemisiae Argyi, Lemna, and Cortex Ulmi, which meet the medicinal standards;

[0014] The three-level screening standards are as follows: the first-level screening removes moldy, worm-eaten, and damaged medicinal materials, and the impurity content is ≤0.5%; the second-level screening removes small sand through a 30-40 mesh screen; and the third-level screening uses near-infrared spectroscopy detection, and the Sapindus saponin content is ≥12%, the Platycladus orientalis flavone content is ≥3%, and the Radix Polygoni Multiflori emodin content is ≥0.1%, and the medicinal materials are divided into hard medicinal materials (Gleditsia sinensis and Radix Polygoni Multiflori), medium medicinal materials (Sapindus, Platycladus orientalis, Ligustri Lucidi Fructus, and Herba Tropaeoli), and light medicinal materials (Folium Artemisiae Argyi, Lemna, and Cortex Ulmi), which are respectively crushed to 20-25 mesh, 25-35 mesh, and 35-40 mesh, and then uniformly mixed.

[0015] As a further scheme of the present application, in step two, the water addition amount is adjusted according to the medicinal material texture ratio, the hard medicinal material accounts for ≥30%, and the total weight of the medicinal materials is 10.5-12 times, the medium medicinal material accounts for ≥60%, and the total weight of the medicinal materials is 9-10.5 times, and the light medicinal material accounts for ≥40%, and the total weight of the medicinal materials is 8.5-9 times, the soaking temperature is stably controlled at 20-25℃, the soaking time is 1.5-3h (2.5-3h for high hard medicinal material ratio, 1.8-2.5h for high medium medicinal material ratio, and 1.5-1.8h for high light medicinal material ratio), and the stirring speed is 50-80r / min for 1-2min every 30-35min.

[0016] As a further scheme of the present application, in step three, the two-stage temperature control boiling is as follows: the electric heating is heated at a rate of 5-6℃ / min to 100℃, boiling is maintained for 5-6min, the temperature is controlled at 90-95℃ (fluctuation ≤±1℃) by turning to a slow fire, and the micro-boiling time is 60-90min (75-90min for high hard medicinal material ratio, and 60-75min for high light medicinal material ratio), the pressing and filtering use a 80-90 mesh stainless steel screen, a pressure of 0.3-0.5MPa is applied, the pressing time is 10-15min, and the residue is reserved after being blown by air flow at a pressure of 0.1-0.2MPa for 3-5min.

[0017] As a further aspect of the present invention: In step four, the amount of water added is adjusted according to the remaining weight of the dregs. When the weight of the dregs is 60%-70% of the initial total weight of the medicinal materials, add 6 times the amount of pure water; when it is 40%-60%, add 5 times the amount of pure water; and when it is ≤40%, add 4 times the amount of pure water. During the repeated decoction process, simmer over low heat for 40-60 minutes. Filter the secondary filtrate through an 80-90 mesh sieve and collect it. After combining the filtrates, first heat the mixture to 100℃ and boil it for 10-12 minutes, then simmer it over low heat at 85℃-90℃ to concentrate it. Monitor and sample the mixture using an online density meter. Stop heating when the solid content of the extract reaches 35%-45% to obtain a viscous traditional Chinese medicine extract.

[0018] As a further aspect of the present invention: In step five, the composite natural plant soap base is composed of coconut oil-based soap base and olive oil-based soap base in a mass ratio of 1:1-1:3, with a soap base purity ≥98% and a moisture content ≤1%. The heating rate is 3℃ / min, and the temperature is raised to 60℃-70℃ and then kept at that temperature for 10-12 minutes to melt. The mass ratio of traditional Chinese medicine extract to liquid soap base is 1:6-1:10 (1:6-1:8 for primary efficacy and 1:8-1:10 for secondary efficacy). The homogenization stirring speed is 300r / min-500r / min (400-500r / min when the effective ingredient concentration is ≥50mg / g and 300-400r / min when <50mg / g), and the stirring time is 15-25 minutes. The uniformity of the mixture is ≥95%, and the particle size is ≤50μm.

[0019] As a further aspect of the present invention: In step six, the surface roughness Ra of the silicone mold cavity is ≤0.8μm. After the soap solution is injected, it is vibrated at a frequency of 50Hz-80Hz and an amplitude of 0.5mm-1.0mm for 3min-5min to remove air bubbles with a diameter ≤0.1mm. The constant temperature and humidity curing conditions are 20℃-25℃ and relative humidity of 40%-60%, with a curing time of 24h-36h (30-36 hours when the soap solution thickness is ≥3cm, and 24-30 hours when it is <3cm). Food-grade silicone oil is used as a release agent for demolding, with an application amount ≤0.5g / m³. 2 When the soap reaches a Shore hardness of 20-25, assist in demolding.

[0020] As a further aspect of the present invention: In step seven, the gradient maturation process is as follows: the first stage is 1-3 days at a temperature of 20-22℃ and a relative humidity of 40%-45%; the second stage is 4-10 days at a temperature of 18-20℃ and a relative humidity of 30%-35%, with a total maturation time of 7-10 days. During the maturation period, ventilation is carried out once a day from 9:00-9:30 and 16:00-16:30, for 30-35 minutes each time, with a ventilation speed of 0.3m / s-0.5m / s. The finished product must meet the following requirements: moisture content of 8%-12%, Shore hardness of 35-45 degrees, effective ingredient retention rate ≥75% (including Sapindus mukorossi saponins, Platycladus orientalis flavonoids, and Polygonum multiflorum emodin), and pH value of 5.5-7.5.

[0021] In addition, this application also provides a hair-nourishing and hair-strengthening shampoo bar based on the synergistic effect of multiple Chinese herbal medicines, which is prepared by a method for preparing hair-nourishing and hair-strengthening shampoo bar based on the synergistic effect of multiple Chinese herbal medicines.

[0022] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0023] 1. This invention, through the selection of authentic medicinal materials and their three-level screening and pulverization according to texture, combined with a two-stage temperature-controlled decoction, repeated decoction and sifting of the dregs, and a creative process design including precise homogenization and stirring of Chinese herbal extracts and compound natural plant soap bases, and gradient maturation of the formed soap body, specifically addresses the shortcomings of existing Chinese herbal hair care products, such as insufficient extraction of effective ingredients, difficulty in fully exerting the synergistic effect of multiple Chinese herbs, poor compatibility between Chinese herbal ingredients and soap bases, and poor efficacy stability. It not only ensures the full dissolution and stable retention of effective ingredients in medicinal materials, but also enhances the synergistic effect of multiple Chinese herbs.

[0025] Figure 1 This is a schematic diagram of the preparation process in an embodiment of the present invention. Detailed Implementation

[0026] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0027] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see the appendix Figure 1 This invention discloses a method for preparing a hair-nourishing and hair-strengthening shampoo bar based on the synergistic effects of multiple traditional Chinese medicines. The preparation method includes the following steps:

[0029] Step 1: Select authentic medicinal materials, screen them in three stages, classify them by texture, pulverize them, and mix them evenly to obtain a pre-treated medicinal material mixture;

[0030] Step 2: Add pure water to the pretreated herbal mixture, control the temperature and soak, stirring regularly during the process;

[0031] Step 3: After soaking, the liquid is boiled in two stages with controlled temperature, then filtered through a sieve, and the first filtrate is collected. The dregs are then blown away and set aside for later use.

[0032] Step 4: Add pure water to the dregs and boil and filter repeatedly. Combine the filtrates and concentrate to the set solid content to obtain the Chinese herbal extract.

[0033] Step 5: Melt the compound natural plant soap base, add the Chinese herbal extract and stir homogenously until the set uniformity is reached;

[0034] Step 6: Pour the soap liquid into the mold and vibrate to remove bubbles. After curing under constant temperature and humidity, assist in demolding to obtain the molded soap body.

[0035] Step 7: Gradually mature the shaped soap body, controlling the temperature, humidity, and ventilation conditions until all indicators meet the standards to obtain the finished product.

[0036] Example 1, please refer to the appendix. Figure 1 This study selected Sapindus mukorossi from Yunnan, Polygonum multiflorum from Sichuan, and Platycladus orientalis leaves from Shandong, along with Gleditsia sinensis, Ligustrum lucidum, Eclipta prostrata, Artemisia argyi, Lemna minor, and Ulmus pumila bark that met medicinal standards. The first stage involved manual removal of moldy and insect-damaged materials to ensure impurity content was ≤0.3%. The second stage involved filtering fine sand through a 35-mesh sieve. The third stage used near-infrared spectroscopy to confirm that Sapindus mukorossi contained 13.2% saponins, Platycladus orientalis leaves contained 3.5% flavonoids, and Polygonum multiflorum contained 0.12% emodin, all meeting standards. Materials were categorized by texture: Gleditsia sinensis and Polygonum multiflorum were classified as hard materials and pulverized to 22 mesh; Sapindus mukorossi, Platycladus orientalis leaves, Ligustrum lucidum, and Eclipta prostrata were classified as medium materials and pulverized to 30 mesh; and Artemisia argyi, Lemna minor, and Ulmus pumila bark were classified as light materials and pulverized to 38 mesh. All materials were then mixed thoroughly to obtain a pre-treated mixture. This process ensures raw material purity through precise screening and allows for simultaneous dissolution of materials of different textures through categorized pulverization, laying the foundation for synergistic efficacy.

[0037] Example 2, please refer to the appendix. Figure 1Add 10 times the weight of pure water (65% of medium-quality herbs) to the pretreated herbal mixture, soak at 23℃ for 2.2 hours, stirring at 65 rpm for 1.5 minutes every 32 minutes. Pour the liquid into a jacketed kettle, heat it to 100℃ at 5.5℃ / min, boil for 5.5 minutes, then simmer at 92℃ (fluctuation ±0.8℃) for 70 minutes. Press the mixture through an 85-mesh sieve under 0.4MPa pressure for 12 minutes, collect the first filtrate, purge the residue with 0.15MPa airflow for 4 minutes, add 5 times the weight of pure water, repeat the decoction process, simmer for 50 minutes, collect the second filtrate, combine the filtrates, boil at 100℃ for 11 minutes to remove impurities, concentrate at 88℃, monitor and sample using an online density meter, stop when the solid content reaches 40%, and obtain a viscous extract. This process maximizes the retention of effective components and avoids waste through dual-stage temperature control and secondary extraction.

[0038] Example 3, please refer to the appendix. Figure 1 Coconut oil-based soap base and olive oil-based soap base were compounded at a mass ratio of 1:2, with a purity of 98.5% and a moisture content of 0.8%. The mixture was heated to 65℃ at a rate of 3℃ / min and held at that temperature for 11 minutes to melt. Traditional Chinese medicine extract (effective ingredient concentration 55mg / g) was added at a mass ratio of 1:8, and the mixture was stirred at 450 rpm for 20 minutes. A laser particle size analyzer determined the uniformity of the mixture to be 96% and the particle size to be 42μm. The soap solution was then poured into a silicone mold and vibrated at a frequency of 65Hz and an amplitude of 0.8mm for 4 minutes to remove bubbles (bubble diameter ≤0.08mm). The soap solution was cured at 23℃ and 50% humidity for 32 hours (soap solution thickness 3.2cm), and demolded with 0.4g / m² food-grade silicone oil (soap hardness 23 Shore). The molded soap was then graded for growth: 1-3 days at 21℃ and 42% humidity, 4-8 days at 19℃ and 33% humidity, with ventilation for 32 minutes each at 9:15 and 16:15 daily (wind speed 0.4m / s). The finished product had a moisture content of 10%, a Shore hardness of 40, an effective ingredient retention rate of 78%, a pH value of 6.2, and excellent stability and user experience.

[0039] Specifically, Yunnan's Sapindus mukorossi, Sichuan's Polygonum multiflorum, and Shandong's Platycladus orientalis are all high-quality producing areas for these traditional medicinal materials, with more abundant accumulation of effective components, ensuring the foundation of product efficacy from the source. The three-level screening forms a progressive quality control system, which not only removes impurities to ensure the purity of raw materials, but also uses near-infrared spectroscopy to lock in the effective components to meet the standards, avoiding the impact of raw material differences on synergistic effects. The classification and pulverization according to texture is designed based on the physical characteristics of different medicinal materials, solving the problem that some medicinal materials dissolve too quickly and others do not dissolve sufficiently due to a single pulverization particle size, providing support for the balanced dissolution of components in the subsequent extraction process.

[0040] Specifically, the amount of water added is adjusted according to the proportion of the medicinal materials. The core is to adapt to the water absorption capacity and the dissolution requirements of different textures of medicinal materials. This avoids insufficient dissolution of hard medicinal materials or excessive soaking of light medicinal materials due to uniform water volume, which would cause component loss. The constant temperature soaking environment can maintain the stability of the cell walls of medicinal materials, reduce the damage of temperature fluctuations to the structure of effective components, and ensure the activity of components. Regular stirring breaks down the concentration gradient barrier between medicinal materials and water, allowing the surface of medicinal materials to always be in contact with fresh water, avoiding the decrease in extraction efficiency caused by local dissolution saturation, and ensuring that effective components are fully dissolved.

[0041] Specifically, the dual-stage temperature-controlled decoction adopts a combination of "high heat activation + low heat slow extraction". High heat quickly raises the temperature to boiling, which can rapidly break the cell wall structure of the medicinal materials and activate the easily soluble effective components. Low heat keeps the temperature constant and provides stable conditions for the slow dissolution of the insoluble components, avoiding the decomposition of components caused by high temperature and long-term decoction. The design of pressing and filtering combined with airflow purging breaks through the limitations of traditional filtration that relies solely on gravity. The filtrate adsorbed in the residue is fully squeezed by pressure, and the residue is then removed by airflow purging, which minimizes the retention of effective components in the residue and improves the extraction and utilization rate.

[0042] Specifically, the secondary decoction is based on the practical need that a large amount of incompletely dissolved effective components remain in the dregs. By dynamically adjusting the amount of water added, the dissolution space corresponding to the remaining weight of the dregs is adapted to avoid excessive water extending the concentration time and insufficient water affecting the extraction effect. The combined filtrate is first boiled to remove impurities and then concentrated to remove volatile impurities and trace foam from the filtrate, ensuring the purity of the extract. Precise concentration is controlled by dual monitoring methods to avoid the concentration being too low, resulting in insufficient component proportion when blending with soap base, and also to prevent the concentration being too high, causing uneven mixing, thus laying the concentration foundation for the synergistic effect of the components.

[0043] Specifically, the choice of compound natural plant soap base eliminates the performance shortcomings of single soap bases. The cleansing power of coconut oil-based soap base complements the gentleness of olive oil-based soap base, satisfying cleansing needs while avoiding scalp irritation. The ratio of extract to soap base is set according to efficacy level, achieving differentiated adaptation of product efficacy to meet the hair care and strengthening needs of different users. The homogenization mixing process adjusts the concentration of effective ingredients by adjusting the rotation speed, solving the problems of high-concentration extracts easily agglomerating and low-concentration extracts easily dispersing unevenly. This ensures that the effective ingredients are evenly dispersed in the soap base, avoiding local enrichment or lack of ingredients, and ensuring stable release of efficacy during use.

[0044] Specifically, the selection of silicone molds focuses on the ease of demolding and surface integrity after soap molding. Low-roughness cavities reduce the adhesion between the soap liquid and the mold, preventing soap breakage during demolding. The vibration defoaming process is specifically designed to address air mixed in during soap liquid pouring. High-frequency, low-amplitude vibration causes tiny air bubbles to gather, rise, and burst, preventing pores in the finished soap and ensuring a dense and uniform soap structure. Constant temperature and humidity curing, along with the use of targeted release agents, provide a stable environment for the slow molding of the soap, preventing uneven internal and external shrinkage that could lead to deformation. Food-grade release agents also reduce friction damage between the soap and the mold, ensuring the integrity and safety of the molded soap.

[0045] Specifically, the gradient curing process follows a "fast first, slow later" water evaporation logic. In the first stage, slightly higher humidity and temperature promote rapid evaporation of water from the soap surface, forming a preliminary stable structure. In the second stage, lower temperature and humidity allow internal water to slowly diffuse to the surface, preventing the soap from cracking or deforming due to excessive water evaporation. The timed ventilation design maintains air circulation in the curing environment, removing evaporated water and trace odors, ensuring the soap has a pleasant scent. The setting of multiple indicators for the finished product forms a complete quality control standard, ensuring product durability through moisture content and hardness, and ensuring product gentleness and efficacy through pH value and effective ingredient retention rate, achieving a dual guarantee of user experience and core effects.

[0046] Working principle:

[0047] First, select authentic medicinal materials such as Sapindus mukorossi from Yunnan and Polygonum multiflorum from Sichuan, along with other standard-compliant Chinese herbs. After a three-stage screening process to remove impurities and ensure the effective components meet standards, the herbs are then categorized by texture, pulverized, and mixed to obtain a pre-treated mixture. Next, adjust the water content of the mixture according to its mass ratio, soak it in a constant-temperature environment, and stir regularly to soften the cell walls of the herbs and promote the dissolution of effective components. Finally, the liquid undergoes a two-stage temperature-controlled decoction (high heat activation +...). (Slowly boil over a low flame) The first filtrate is collected by pressing and filtering through a sieve. The residue is then swept away by airflow and set aside. Water is added to the residue according to the remaining weight, and the process is repeated by boiling and filtering. The two filtrates are combined, purified, and concentrated to obtain a Chinese herbal extract with a set solid content. Then, a natural plant soap base composed of coconut oil and olive oil is melted and added to the Chinese herbal extract in a ratio appropriate to the efficacy level. The mixture is homogenized and stirred until evenly dispersed. The soap solution is then poured into a silicone mold, vibrated to remove bubbles, and cured under constant temperature and humidity conditions. Once the desired consistency is achieved, the soap is demolded to obtain the shaped soap body. Finally, a gradient curing process is performed on the shaped soap body, controlling the temperature and humidity and timed ventilation. Once the soap body meets the standards for moisture, hardness, and retention rate of effective ingredients, the hair-nourishing and strengthening shampoo soap is obtained. This completes the entire workflow.
