Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, and more specifically, to a dandruff-controlling oil shampoo made from a traditional Chinese medicine compound of Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. Background Technology

[0002] Most commercially available anti-dandruff and oil-controlling shampoos rely on chemical anti-dandruff agents such as zinc pyrithione and ketoconazole, as well as sulfate surfactants such as sodium lauryl sulfate. Although they are effective in the short term, they can easily damage the scalp barrier, causing discomfort such as redness and itching on sensitive scalps. Moreover, the oil-controlling effect is short-lived, usually lasting up to 8 hours.

[0003] Traditional Chinese medicine shampoos, while marketed as gentle, suffer from three major drawbacks: 1) Low extraction rate of active ingredients from Chinese herbs, with a traditional water extraction rate of <30%, resulting in insufficient dandruff control and oil control effects; 2) The use of single chemical preservatives, such as sodium benzoate, which can irritate the scalp if the concentration is too high, or result in a short shelf life of <6 months if the concentration is too low; 3) Crude manufacturing processes, with poor compatibility between lipid-soluble components such as ceramides and aqueous systems, leading to easy stratification and insufficient stability.

[0004] Therefore, it is of great practical significance to provide a mild, non-irritating, long-lasting dandruff-removing and oil-controlling shampoo with a stable system and safe preservation. Summary of the Invention

[0005] In view of this, the present invention proposes a compound traditional Chinese medicine formula of Sophora flavescens, Platycladus orientalis, and Phellodendron chinense to control dandruff and oil, aiming to solve the problems of traditional shampoos in the current technology, such as high chemical irritation, short-lasting oil control, and discomfort to sensitive scalps, as well as the problems of traditional Chinese medicine shampoos, such as poor antiseptic performance, poor stability, low extraction rate of active ingredients of Chinese medicine, and poor synergistic effect.

[0006] This invention proposes a compound traditional Chinese medicine shampoo for dandruff control and oil control, comprising the following components by mass fraction: Sophora flavescens root extract 2.5-3.0%, Platycladus orientalis leaf extract 3.5-4.5%, Phellodendron chinense bark extract 1.0-2.0%, Spiraea japonica extract 0.8-1.2%, ceramide 0.2-0.4%, sodium cocoyl glutamate 10-16%, Sapindus mukorossi saponins 2-4%, xanthan gum 0.6-1%, preservative system 0.2-0.4%, panthenol 0.8-1.2%, pure water 67.3-77.4%.

[0007] Furthermore, the weight ratio of sodium cocoyl glutamate to Sapindus mukorossi saponin is 3-5:1.

[0008] Furthermore, the preservative system is a mixture of rosemary extract and sodium benzoate, with a mass ratio of rosemary extract to sodium benzoate of 2 to 5:1.

[0009] A method for preparing a traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo, comprising the following steps: S1. Preparation of Chinese herbal extracts: Sophora flavescens root, Platycladus orientalis leaf, and Phellodendron chinense bark are pulverized, then compound plant enzymes are added for enzymatic hydrolysis, followed by extraction and concentration to obtain a compound extract of Sophora flavescens-Platycladus orientalis-Phellodendron chinense Chinese herbal medicines. S2. Aqueous phase preparation: Xanthan gum was added to pure water and stirred until dissolved. Ceramide, panthenol and preservative system were added in sequence. The mixture was heated and kept at a constant temperature to obtain the aqueous phase. S3. Preparation of the functional phase: The Chinese herbal compound extract, meadowsweet extract and panthenol are mixed and ultrasonically dispersed to obtain the functional phase; S4. Emulsification and mixing: Add the functional phase to the aqueous phase, perform high-speed shear emulsification, add sodium cocoyl glutamate and soapberry saponins, stir until completely dissolved, adjust the pH to obtain an emulsion; S5. After filtration through a filter cloth, the content of its effective ingredients, pH, microorganisms and other indicators are tested. If it passes the test, it is bottled to obtain the Chinese herbal compound anti-dandruff and oil-controlling shampoo.

[0010] Furthermore, the Sophora flavescens root, Platycladus orientalis leaf, and Phellodendron chinense bark mentioned in S1 are pulverized to 80-100 mesh, and the compound plant enzyme includes cellulase and pectinase, with a mass ratio of cellulase to pectinase of 1:1.5-2.5; the enzymatic hydrolysis parameters are: temperature 45-55℃ and time 25-35min.

[0011] Furthermore, the extraction described in S1 is supercritical CO2 extraction, and the parameters for supercritical CO2 extraction are: pressure 28~35MPa, temperature 40~55℃, and time 15~2h; the concentration is vacuum concentration, and the parameters for vacuum concentration are: vacuum degree 0.06~0.1MPa and temperature 50~60℃; the relative density of the extract is 1.10~1.20g / mL.

[0012] Furthermore, the heating described in S2 is gradient heating, and the gradient heating parameters are: heating rate 5~10℃ / min, temperature 55~65℃; the holding time is 5~15min; the stirring parameters are: rotation speed 300~500r / min, time 20~30min, temperature 50~70℃.

[0013] Furthermore, the ultrasonic parameters described in S3 are: power 150~250W, time 10~20min, temperature 30~40℃, and frequency 20~30kHz.

[0014] Furthermore, the high-speed shear emulsification parameters in S4 are: rotation speed 6000~10000 r / min, time 10~20 min; the pH is adjusted to 5.5~6.0; the stirring parameters are: rotation speed 500~800 r / min, time 15~25 min, temperature 40~50℃.

[0015] Furthermore, the filter cloth described in S5 has a pore size of 200 mesh.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The shampoo of this invention uses sodium cocoyl glutamate as an amino acid surfactant, which is combined with plant extracts and does not produce any irritating reactions such as stinging or redness.

[0017] The shampoo of this invention uses a compound extract of traditional Chinese medicine (matrine, flavonoids, berberine) to synergistically inhibit Malassezia, thus prolonging the oil-controlling effect and reducing the dandruff recurrence rate.

[0018] The shampoo of this invention optimizes the solubility of active ingredients through enzymatic hydrolysis-supercritical extraction, and ensures uniform particle size through high-speed shear emulsification. It can be stored at room temperature for 12 months without stratification or abnormal viscosity.

[0019] The shampoo of this invention uses rosemary extract and sodium benzoate as a preservative system for synergistic preservation. Microbial challenge tests show that the inhibition rate against Escherichia coli, Staphylococcus aureus and Candida albicans is significantly improved, and there is no risk of chemical preservative residue.

[0024] The terms “include,” “including,” “have,” “contain,” etc., used in this article are all open-ended terms, meaning that they include but are not limited to.

[0025] A compound herbal shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense for dandruff control and oil control, comprising the following components by mass fraction: Sophora flavescens root extract 2.5-3.0%, Platycladus orientalis leaf extract 3.5-4.5%, Phellodendron chinense bark extract 1.0-2.0%, Spiraea japonica extract 0.8-1.2%, ceramide 0.2-0.4%, sodium cocoyl glutamate 10-16%, Sapindus mukorossi saponins 2-4%, xanthan gum 0.6-1%, preservative system 0.2-0.4%, panthenol 0.8-1.2%, pure water 66.3-77.4%.

[0026] In this invention, the herbal compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense is further preferably composed of the following components by mass fraction: Sophora flavescens root extract 2.6-3.0%, Platycladus orientalis leaf extract 3.8-4.5%, Phellodendron chinense bark extract 1.3-2.0%, Spiraea japonica extract 0.9-1.2%, ceramide 0.25-0.4%, sodium cocoyl glutamate 10-15%, Sapindus mukorossi saponins 2-3.5%, xanthan gum 0.7-1%, preservative system 0.25-0.4%, panthenol 0.9-1.2%, pure water 66.3-77.1%.

[0027] This invention adds Sophora flavescens, Platycladus orientalis, and Phellodendron chinense to the anti-dandruff and oil-controlling shampoo. The Sophora flavescens root extract mainly consists of alkaloids such as matrine, which precisely targets and inhibits bacteria, has strong anti-inflammatory activity, and is gentle enough for sensitive scalps with no obvious risk of irritation. The Platycladus orientalis leaf extract mainly consists of flavonoids and volatile oils, which can control oil and repair the scalp, has strong antioxidant properties, can reduce the oxidation loss of active ingredients, and improve the stability of the formula. The Phellodendron chinense bark extract mainly contains berberine and berberine, which have a dual effect of antibacterial and oil control, and also have a certain anti-inflammatory and repairing ability, which can enhance the long-term effect of anti-dandruff and oil control. Furthermore, the synergistic effect of the Sophora flavescens root extract, Platycladus orientalis leaf extract, and Phellodendron chinense bark extract, with the synergistic effect of matrine and berberine, enhances the inhibition rate of Malassezia compared to single ingredients, avoiding potential drug resistance from single antibacterial components. It also covers more harmful scalp bacteria, reducing dandruff recurrence. Phellodendron chinense bark extract regulates sebum secretion, Platycladus orientalis leaf extract optimizes oil metabolism, and Sophora flavescens root extract inhibits the decomposition of oil by bacteria. All three contain anti-inflammatory components, synergistically inhibiting the release of inflammatory factors on the scalp and relieving redness and itching. Simultaneously, the antioxidant and barrier-repairing effects of Platycladus orientalis leaf can neutralize any slight irritation that Sophora flavescens and Phellodendron chinense may cause, improving suitability for sensitive scalps. The flavonoid antioxidants in Platycladus orientalis leaf can reduce the oxidative decomposition of heat-sensitive components such as matrine and berberine. Combined with supercritical extraction technology, the retention rate of active ingredients reaches over 90%, extending the product's shelf life and ensuring the stability of its efficacy.

[0028] This invention adds meadowsweet extract to the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. Meadowsweet is rich in polyphenols and ellagic acid, which can inhibit 5α-reductase activity (reducing oil synthesis from the root), while also tightening pores, anti-inflammatory and antibacterial properties, and is suitable for use in the shampoo of this invention that strengthens oil control and regulates sebum secretion.

[0029] The preferred weight ratio of sodium cocoyl glutamate to Sapindus mukorossi saponins in this invention is 3-5:1, more preferably 4-5:1.

[0030] This invention adds sodium cocoyl glutamate to the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. Sodium cocoyl glutamate serves as a core amino acid-type surfactant, possessing a unique structure that combines hydrophilicity (glutamate groups) and lipophilicity (cocoyl groups). This allows for gentle and efficient cleansing of the scalp, protecting the scalp barrier, and gently removing excess sebum and dirt. It controls oil without damaging the scalp barrier, leaving no dryness or tightness. It is low-irritant (homogeneous with human stratum corneum components), suitable for sensitive scalps, avoiding stinging, redness, and the risk of eye irritation. It also helps the active ingredients of the traditional Chinese medicine (such as matrine) to disperse evenly and the repairing ingredients (such as ceramides) to penetrate, enhancing the anti-dandruff and barrier repair effects. Furthermore, it generates fine and stable foam that is easy to rinse without residue, is compatible with the formula system, and maintains viscosity and storage stability.

[0031] This invention adds Sapindus mukorossi saponins to the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. Sapindus mukorossi saponins are natural glycoside surfactants extracted from Sapindus mukorossi fruit. Their molecular structure has both lipophilic and hydrophilic groups, which can effectively emulsify scalp oil and dirt. In synergy with amino acid surfactants, they can improve cleaning efficiency while avoiding the irritation of traditional chemical surfactants. They can inhibit the proliferation of microorganisms such as Malassezia and Propionibacterium acnes, help relieve scalp inflammation, and reduce the probability of dandruff formation. As a natural nonionic surfactant, it causes little damage to the scalp barrier and can be tolerated by sensitive scalps.

[0032] The preservative system described in this invention is a mixture of rosemary extract and sodium benzoate. The weight ratio of rosemary extract to sodium benzoate is preferably 2 to 5:1, and more preferably 3 to 5:1.

[0033] This invention adds a preservative system to the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. The preservative system includes rosemary extract and sodium benzoate, which can inhibit the growth and reproduction of microorganisms (bacteria, fungi, yeasts, etc.) in the product, preventing the product from deteriorating due to microbial contamination during production, storage, and use. The introduction of rosemary extract, a plant-derived ingredient, into this system reduces the concentration of chemical preservatives used, thus reducing potential irritation to the scalp. Furthermore, rosemary extract itself has certain antioxidant properties, which can help protect the active ingredients in the shampoo, such as matrine and flavonoids, reducing their inactivation due to oxidation and improving the stability of the product's anti-dandruff and oil-controlling efficacy.

[0034] This invention adds panthenol to the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. The small molecular structure of panthenol can quickly penetrate into the scalp stratum corneum, deeply moisturize and lock in moisture, relieve scalp dryness, reduce dry and split ends, and improve hair softness. It can soothe scalp irritation, reduce the discomfort of surfactants and the environment on sensitive scalps, and reduce redness and itching. It can also help repair the scalp barrier, enhance the moisture content and tolerance of the stratum corneum, and synergistically strengthen the barrier protection with ceramides. It works synergistically with other substances in the formula to improve the mildness of the formula, ensure compatibility with the active ingredients of traditional Chinese medicine, without affecting the anti-dandruff and oil-controlling effects, and optimize the user experience without tightness after rinsing.

[0035] This invention adds ceramides to the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. Ceramides can fill lipid gaps, reconstruct a complete barrier structure, replenish scalp stratum corneum lipids, rebuild damaged barriers, reduce moisture loss, and improve scalp dryness. They can also enhance scalp tolerance, alleviate sensitivity issues such as redness and itching, and reduce the impact of external stimuli. Furthermore, they can help inhibit Malassezia, reduce compensatory oil production on the scalp, prolong the anti-dandruff and oil-controlling effect, and fill gaps in hair cuticles, reducing dryness and split ends, and improving the dryness caused by oil-controlling shampoos.

[0036] This invention adds xanthan gum to the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron chinense. The xanthan gum acts as a thickening and stabilizing ingredient. The shampoo prepared by this invention contains multiphase components such as traditional Chinese medicine extracts (fluid extract paste) and ceramides (lipid-soluble, easily precipitated). After adding xanthan gum, the components can be evenly dispersed by constructing a three-dimensional network structure; it also helps stabilize foam, reduce rinsing residue, optimize the refreshing user experience, and ensure compatibility with active ingredients and preservative systems in the formula, maintaining pH balance and component stability.

[0037] A method for preparing a traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo, comprising the following steps: S1. Preparation of Chinese herbal extracts: Sophora flavescens root, Platycladus orientalis leaf, and Phellodendron chinense bark are pulverized, then compound plant enzymes are added for enzymatic hydrolysis, followed by extraction and concentration to obtain a compound extract of Sophora flavescens-Platycladus orientalis-Phellodendron chinense Chinese herbal medicines. S2. Aqueous phase preparation: Xanthan gum was added to pure water and stirred until dissolved. Ceramide, panthenol and preservative system were added in sequence. The mixture was heated and kept at a constant temperature to obtain the aqueous phase. S3. Preparation of the functional phase: The Chinese herbal compound extract, meadowsweet extract and panthenol are mixed and ultrasonically dispersed to obtain the functional phase; S4. Emulsification and mixing: Add the functional phase to the aqueous phase, perform high-speed shear emulsification, add sodium cocoyl glutamate and soapberry saponins, stir until completely dissolved, adjust the pH to obtain an emulsion; S5. After filtration through a filter cloth, the content of its effective ingredients, pH, microorganisms and other indicators are tested. If it passes the test, it is bottled to obtain the Chinese herbal compound anti-dandruff and oil-controlling shampoo.

[0038] S1. Preparation of Chinese herbal extracts: Sophora flavescens root, Platycladus orientalis leaf, and Phellodendron chinense bark are pulverized, then compound plant enzymes are added for enzymatic hydrolysis, followed by extraction and concentration to obtain a compound extract of Sophora flavescens-Platycladus orientalis-Phellodendron chinense Chinese herbal medicines. In S1 of this invention, the Sophora flavescens root, Platycladus orientalis leaf, and Phellodendron chinense bark are preferably pulverized to 80-100 mesh, more preferably to 80-90 mesh; the compound plant enzyme comprises cellulase and pectinase, and the mass ratio of cellulase to pectinase is preferably 1:1.5-2.5, more preferably 1.15-2; the enzymatic hydrolysis parameters are preferably: temperature 45-55℃ and time 25-35 min, more preferably temperature 45-50℃ and time 25-30 min.

[0039] This invention adds a compound plant enzyme to the preparation method of the traditional Chinese medicine compound anti-dandruff and oil-controlling shampoo containing Sophora flavescens, Platycladus orientalis, and Phellodendron amurense. The compound plant enzyme includes cellulase and pectinase, which work together to break down the cell walls and intercellular matrix of Sophora flavescens, Platycladus orientalis leaves, and Phellodendron amurense. Cellulase decomposes the cellulose skeleton of the cell wall, and pectinase degrades the pectin binding substances between cells, thus opening the release channels of active ingredients and improving the dissolution rate of active ingredients. It can also soften the tissue and loosen the structure of the Chinese medicine raw materials, thereby improving the dissolution rate of target active ingredients such as matrine, flavonoids, and berberine, while reducing the dissolution of ineffective impurities such as wax and coarse fiber. At the same time, it shortens the subsequent supercritical CO2 extraction time, ensuring the purity and efficacy of the extract.

[0040] The extraction described in S1 of this invention is supercritical CO2 extraction, and the preferred parameters for supercritical CO2 extraction are: pressure 28~35MPa, temperature 40~55℃, and time 1.5~2h, more preferably pressure 28~32MPa, temperature 45~50℃, and time 1.5~1.8h; the concentration is vacuum concentration, and the preferred parameters for vacuum concentration are: vacuum degree 0.06~0.1MPa and temperature 50~60℃, more preferably vacuum degree 0.06~0.08MPa and temperature 50~55℃; the relative density of the extract is preferably 1.10~1.20g / mL, more preferably 1.10~1.15g / mL.

[0041] In this invention, the essential purpose of extraction is to efficiently and accurately separate and obtain active ingredients with dandruff-reducing, oil-controlling, and anti-inflammatory effects from Chinese medicinal materials, providing a material basis for the core efficacy of the product; it efficiently extracts target active ingredients such as matrine, flavonoids, and berberine from Sophora flavescens, Platycladus orientalis leaves, and Phellodendron chinense, and supercritical CO2 extraction can reduce solvent residue, which is in line with the mild formulation positioning; it separates ineffective impurities such as wax and coarse fiber from the raw materials, improves the purity of the extract, and avoids impurities affecting the stability and efficacy of subsequent formulations; the low-temperature environment protects heat-sensitive active ingredients, reduces oxidative decomposition, and ensures that the dandruff-reducing and oil-controlling effects are not lost; and it can provide highly active raw materials for subsequent aqueous phase mixing and emulsification processes.

[0042] In this invention, the concentration step is vacuum decompression concentration, which can concentrate and protect active ingredients at low temperatures. Under low temperature, decompression, and low pressure environments, the oxidation and decomposition of heat-sensitive components such as matrine and flavonoids are reduced, avoiding damage to the core efficacy by high temperatures. Excess water and low-boiling-point impurities in the extract after supercritical extraction are removed, increasing the concentration of active ingredients and ensuring that a small amount is added to achieve the effect of dandruff control and oil control, avoiding excessive solvent from affecting the stability of the formula. The extract is concentrated to a lower relative density to adapt to subsequent aqueous phase mixing and emulsification processes, ensuring uniform dispersion with other ingredients and preventing stratification. The trace waxes and coarse fibers remaining during the extraction process are further separated to improve the purity of the extract and prevent impurities from causing the shampoo to be cloudy or the skin to feel sticky.

[0043] S2. Aqueous phase preparation: Xanthan gum was added to pure water and stirred until dissolved. Ceramide, panthenol and preservative system were added in sequence. The mixture was heated and kept at a constant temperature to obtain the aqueous phase. The heating described in S2 is gradient heating, and the gradient heating parameters are preferably: heating rate 5~10℃ / min, temperature 55~70℃, more preferably heating rate 5~8℃ / min, temperature 55~65℃; the holding time is preferably 5~15min, more preferably 5~10min; the stirring parameters are preferably: rotation speed 300~500r / min, time 20~30min, temperature 50~70℃, more preferably rotation speed 300~400r / min, time 25~30min, temperature 50~65℃.

[0044] In this invention, stirring is selected during the aqueous phase preparation process to prevent xanthan gum from clumping, allowing it to fully swell in the aqueous phase, ensuring stable system viscosity, facilitating uniform dispersion of components such as ceramides and panthenol, preventing the precipitation of lipid-soluble components, ensuring the homogeneity of the aqueous phase, accelerating the dissolution efficiency of each component, and shortening the aqueous phase preparation time; it also enables the uniform dissolution / dispersion of components such as xanthan gum, ceramides, panthenol, and preservative systems, avoiding clumping and ensuring the stability of the aqueous phase.

[0045] S3. Preparation of the functional phase: The Chinese herbal compound extract, meadowsweet extract and panthenol are mixed and ultrasonically dispersed to obtain the functional phase; The preferred ultrasonic parameters in S3 of this invention are: power 150~250W, time 10~20min, temperature 30~40℃, and frequency 20~30kHz, and more preferably power 150~200W, time 10~16min, temperature 30~35℃, and frequency 20~25kHz.

[0046] In this invention, the ultrasonic treatment selected during the aqueous phase preparation process involves ultrasonically treating the Chinese herbal raw materials before enzymatic hydrolysis or extraction. The cavitation effect of sound waves generates tiny bubbles that break down, disrupting the plant cell walls and intercellular matrix. This allows components such as matrine and berberine to more easily contact the extraction medium or enzyme solution, improving the subsequent extraction rate. Applying ultrasound to the mixing of the herbal extract and the aqueous phase can quickly break up extract aggregates (such as tiny particles of flavonoids), resulting in more uniform dispersion in the aqueous phase and preventing uneven concentrations or stratification during subsequent emulsification. For lipid-soluble components such as ceramides, the mechanical vibration and cavitation effect of ultrasound can reduce the interfacial tension between them and the aqueous phase, accelerating dispersion and dissolution. Combined with the aqueous phase heating process, this further avoids crystallization during low-temperature storage, improving formulation stability. In the aqueous phase preparation, ultrasound can replace some high-speed stirring, accelerating the swelling of xanthan gum and the dissolution of panthenol. This shortens the operation time during aqueous phase preparation, reduces bubbles generated by stirring, and optimizes the subsequent degassing step.

[0047] S4. Emulsification and mixing: Add the functional phase to the aqueous phase, perform high-speed shear emulsification, add sodium cocoyl glutamate and soapberry saponins, stir until completely dissolved, adjust the pH to obtain an emulsion; The high-speed shear emulsification parameters in S4 of this invention are preferably: rotation speed 6000~10000 r / min, time 10~20 min, more preferably rotation speed 6000~8000 r / min, time 15~20 min; the pH is preferably adjusted to 5.5~6.0, more preferably 5.5~5.8; the stirring parameters are preferably: rotation speed 500~800 r / min, time 15~25 min, temperature 40~50℃, more preferably rotation speed 600~800 r / min, time 15~20 min, temperature 40~45℃.

[0048] In this invention, high-speed shear emulsification is selected during the aqueous phase preparation process. The high-speed shear emulsification addresses two main issues: firstly, it breaks down fat-soluble components like ceramides into tiny particles / droplets, which are then uniformly dispersed in the aqueous matrix, reducing interfacial tension, preventing crystallization and precipitation during low-temperature storage, and improving the overall uniformity of the formula; secondly, it ensures that active ingredients such as matrine and berberine are uniformly dispersed in the surfactant and aqueous system, allowing for more even contact with the scalp during subsequent use, improving Malassezia inhibition and oil control, while also aiding in the penetration and absorption of repairing ingredients such as ceramides and panthenol; thirdly, it results in a finer texture after homogenization, avoiding friction and irritation during shampooing due to a grainy feel; fourthly, it improves foam performance, making the foam finer and denser, enhancing the user experience, and reducing residue during rinsing; and fifthly, standardized high-speed shear parameters (speed, time, temperature) allow for precise control of the emulsification endpoint, reducing viscosity and appearance differences between batches, improving production stability, and ensuring that the shampoo prepared according to this invention meets the quality control requirements for industrial mass production.

[0049] S5. After filtration through a filter cloth, the content of its effective ingredients, pH, microorganisms and other indicators are tested. If it passes the test, it is bottled to obtain the Chinese herbal compound anti-dandruff and oil-controlling shampoo.

[0050] The filter cloth described in S5 of this invention has a pore size of 200 mesh.
