Description

Technical Field

[0001] This application relates to the field of daily chemical products technology, specifically to the process of making antibacterial shampoo from Miao herbs and its manufacturing process. Background Technology

[0002] In the field of modern shampoo technology, with the fast pace of life and increased mental stress, scalp and hair health issues are receiving increasing attention. Problems such as dry, split, frizzy, and easily tangled hair, as well as dandruff and excessive sebum secretion, are common. Although there are many types of shampoos on the market, most still rely on chemical ingredients, posing a potential risk of damaging the scalp barrier and affecting hair health with long-term use. Furthermore, the safety and actual efficacy of additives in some products lack sufficient assurance, failing to meet consumers' growing demand for "safe and effective" and "natural and gentle" products. Therefore, developing truly cleansing and conditioning shampoos with natural and safe plant-based ingredients has become an important direction for the industry.

[0003] However, several technical bottlenecks and defects still exist in existing shampoos containing natural ingredients, mainly in the following aspects: (1) Over-reliance on chemical components: Most products are still based on synthetic surfactants, silicone oil and preservative systems. Although they can improve hair quality in the short term, long-term use may damage the scalp microecology, leading to problems such as scalp sensitivity and dependent dandruff. (2) The activity and stability of natural ingredients are difficult to guarantee: plant extracts are prone to degradation and inactivation during high-temperature preparation or long-term storage, which affects the final efficacy of the product and restricts the actual amount added in the formula and the duration of the effect. (3) Potential risks to scalp health and tolerance: Some anti-dandruff products on the market rely on synthetic anti-dandruff ingredients such as zinc pyrithione and ketoconazole. Although they are fast-acting, they may cause dry scalp, itching, or even drug resistance, leading to recurring dandruff after discontinuation. (4) Insufficient microbial control in production and storage: Natural ingredients provide conditions for microbial growth, while existing processes often lack systematic and strict safeguards for microbial detection and control, affecting product safety and quality stability.

[0004] Based on the above statements, this application provides a process flow for preparing antibacterial shampoo using Miao herbs. Summary of the Invention

[0005] To address the shortcomings of existing shampoos, such as over-reliance on chemical ingredients, difficulty in maintaining the activity of natural ingredients, potential risks to scalp health, and insufficient microbial control, this application provides a process for preparing antibacterial shampoo using Miao herbs.

[0017] Secondly, this application provides a manufacturing process for antibacterial shampoo made from Miao herbs, employing the following technical solution: The production process of antibacterial shampoo made from Miao herbs includes the following steps: S1. Material preparation: Accurately weigh the required amounts of materials for phase A, phase B and phase C according to the formula, and set them aside for later use; S2, Heating and dissolving phase A: Add phase A raw materials sequentially to the mixing pot, heat to 70-80℃, and stir at 200-300 rpm for 20-40 minutes until all materials are completely dissolved; S3, B phase addition and constant temperature mixing: Keep the system temperature at 75-85℃, add the B phase raw material to the mixing pot in sequence, and stir at 150-250rpm for 0.5-1.5h until it is completely dissolved; S4 and C phase addition and low-temperature mixing: Lower the system temperature to 40-50℃, add the C phase raw material in sequence, and stir at 100-200 rpm for 0.5-1.5h until it is completely dissolved; S5. Cooling and Inspection: Cool the system to 30-40℃, take samples for inspection, and discharge the material after passing the inspection to obtain the antibacterial shampoo made from Miao herbs.

[0018] Thirdly, this application provides the application of antibacterial shampoo made from Miao herbal decoctions, employing the following technical solution: Application of Miao herbal decoction for antibacterial shampoo in the preparation of personal care products for treating problem scalps.

[0019] Preferably, the problem scalp manifests as at least one of dandruff, itching, excessive oiliness, or hair breakage.

[0020] In summary, this application has the following beneficial effects: 1. The formula exhibits significant synergistic effects, combining cleansing, conditioning, and multiple care benefits: The formula of this application achieves synergistic effects through the precise combination of three phases of raw materials: A, B, and C. Phase A, sodium lauryl ether sulfate and ammonium lauryl sulfate, together form a highly efficient cleansing and foaming base, while the acrylic copolymer in the stabilizer ensures the stability of the system viscosity. Phase B, cocamidopropyl betaine, further enhances the gentleness of cleansing and the richness of foam. Synergistically with guar gum hydroxypropyltrimethylammonium chloride, it provides a smooth and conditioning feel to the hair while cleansing, effectively combating dryness. Phase C, as the core functional component, combines piroctone ketone ethanolamine salt with a complex extract of Miao herbs (including extracts of Sophora flavescens root, Phellodendron amurense bark, Cnidium monnieri, etc.) to complement each other in antibacterial and anti-inflammatory effects, strengthening the fundamental effects of dandruff removal and itch relief. Camellia seed nourishing extract and Camellia seed oil deeply nourish the hair strands, improving dryness and frizz. In addition, ingredients such as Zanthoxylum bungeanum peel extract in the formula help activate scalp vitality. This complex system, composed of various natural herbal extracts and carefully selected synthetic ingredients, can simultaneously address multiple scalp problems such as dandruff, itching, oiliness, and breakage.

[0021] 2. The preparation process effectively protects active ingredients and ensures the high performance of the final product: This application creatively adopts a staged temperature-controlled "cooking" process. Specifically, phase A is first treated at 70-80℃ to completely dissolve stabilizers and other components, and then phase B is added at 75-85℃ to ensure its uniform dispersion. Most importantly, phase C, containing herbal extracts, piroctone ketone ethanolamine salt, fragrance, and heat-sensitive active ingredients such as polydimethylsiloxane, is added only under mild conditions of 40-50℃. This precise low-temperature addition process minimizes the risk of deactivation of herbal active ingredients, aroma loss, or silicone oil emulsion demulsification due to high temperatures, thus ensuring that these core ingredients can fully exert their intended conditioning, nourishing, dandruff-removing, and smoothing effects in the final product.

[0022] 3. High product safety with a dual-layer anti-corrosion barrier: The formula of this application uses natural herbal ingredients such as Sophora flavescens root extract, Phellodendron amurense bark extract, and Camellia oleifera seed extract as the core efficacy sources, reducing excessive reliance on single synthetic chemical components and making the product more gentle. Simultaneously, by adding synergistic preservatives in the later stages of product preparation, and forming a compound anti-corrosion system with methylparaben and propylparaben in phase B, this dual protection effectively inhibits microbial growth. Combined with strict "cooling inspection" and "microbial inspection" processes in the production flow, the hygiene, safety, and quality stability of the product are ensured during storage and use, providing users with a safe and reliable user experience.

[0032] Table 2. Raw materials and corresponding feed amounts included in Examples 2-5 Comparative Examples 1-5 The antibacterial shampoo made from Miao herbs follows the same production process and ingredient ratios as in Example 1. The only difference between Example 1 and Example 2 is the amount (by weight) of the ingredients, as shown in Table 3.

[0033] Table 3. Raw materials and corresponding input quantities for Comparative Examples 1-5 Experimental verification and evaluation of the comprehensive performance of antibacterial shampoo made from Miao herbs 1. Experimental Objective This experiment aims to verify the comprehensive advantages of the formulations of this application (Examples 1-5) in terms of dandruff removal, antibacterial properties, hair care, scalp comfort, and formulation stability through a series of objective tests and subjective evaluations, especially the indispensable synergistic effect of its core active ingredients (pyrrolidone ethanolamine salt, herbal extract, and camellia seed nourishing components).

[0034] 2. Grouping of experimental samples Experimental group: Examples 1-5; Control group: Comparative example 1: Blank control group (without core active ingredients); Comparative Example 2: Anti-dandruff group (without piroctone ethanolamine salt); Comparative Example 3: Herb-deficient group (compound extract of herb without seedlings); Comparative Example 4: Nourishing Group (without Camellia seed extract and oil); Comparative Example 5: Traditional anti-dandruff group (using ZPT anti-dandruff agent to replace the core active ingredient of this application).

[0035] 3. Experimental Methods and Results (1) In vitro antibacterial test – targeting Malassezia The formulations in Examples 1-5 demonstrated superior antibacterial activity against Malassezia, the main pathogen causing dandruff, compared to the comparative formulations.

[0036] Agar diffusion method (perforation method): Prepare a Malassezia bacterial suspension and adjust the concentration to 0.5 McFarland turbidity standard; pour sterile PDA medium into a plate, and after solidification, take 100 μL of the bacterial suspension and spread it evenly; use a sterile perforator to punch holes with a diameter of about 6 mm on the plate; add 50 μL of each experimental sample (Examples 1-5, Comparative Examples 1-5) to the holes respectively; place the plate in a 28°C constant temperature incubator and incubate for 72 hours; use vernier calipers to measure the diameter of the inhibition zone (including the hole itself); the results are shown in Table 4.

[0037] (2) Hair combing force test experiment The hair washed with the formulas in Examples 1-5 showed better smoothness and combability than the hair washed with the formulas in Comparative Examples 1-5.

[0038] The combing process was simulated using a texture analyzer. The work required to comb damaged hair strands was measured. The lower the combing work, the smoother the hair. Standard damaged hair strands of the same length and weight were prepared. A 12% sample solution was prepared with 150 ppm hard water. The hair strands were washed, rinsed, and dried. The hair strands were fixed on the fixture of the texture analyzer and combed with a comb probe. The combing work value output by the instrument software was recorded, as shown in Table 4.

[0039] (3) Chicken embryo chorioallantoic membrane experiment The potential irritation of the formulation to sensitive tissues such as the ocular mucosa was assessed to verify the mildness of the formulation in this application.

[0040] Using the chorioallantoic membrane of chicken embryos to simulate the conjunctiva of the human eye, we observed the changes in blood vessels after the sample came into contact with the membrane and scored the irritation: Chicken embryos that had been incubated for 10 days were taken, and the chorioallantoic membrane was exposed by opening a window; 300 μL of sample solution was dropped onto the chorioallantoic membrane (CAM); after 5 minutes of action, it was gently rinsed with physiological saline; the changes in blood vessels on the membrane were observed under a stereomicroscope and compared with the negative control (physiological saline) and the positive control (1% SDS). The scores were scored according to the standard scoring table, as shown in Table 4.

[0041] Table 4. Results of the comprehensive performance test of antibacterial shampoo made from Miao herbal decoction This experiment systematically evaluated the comprehensive performance of the herbal decoction antibacterial shampoo formula of this application through three tests: in vitro antibacterial activity, hair combing ability, and irritation to the chorionic allantoic membrane of chicken embryos. The experimental results fully verified that the formula of this application has significant advantages in terms of core efficacy, hair care performance, and gentleness, and that its core components play an indispensable synergistic role.

[0042] Regarding the core antibacterial efficacy, in vitro antibacterial experiments showed that Examples 1-5 all produced significant inhibition zones against Malassezia. A comparison with Comparative Examples 1-5 clearly revealed the roles of each core component: Comparative Example 1 (blank control) showed almost no antibacterial effect, demonstrating the necessity of the core component; Comparative Example 2 (lacking piroctone olamine salt) showed significantly reduced antibacterial activity, indicating that this component is the main force behind potent antibacterial activity; the inhibition zone of Comparative Example 3 (lacking herbal compound extract) was also significantly smaller than that of the optimal Example 1, indicating that the herbal extract not only possesses certain antibacterial activity itself but also exhibits a synergistic effect with piroctone olamine salt. Furthermore, the antibacterial effect of Comparative Example 5 (traditional ZPT group) was inferior to some examples of this application, further highlighting the superior efficacy of the formulation in this application.

[0043] Regarding hair care performance, the results of the hair combing power test and the trend of antibacterial efficacy complemented each other. Examples 1-5 showed the lowest combing power, indicating that the hair was the smoothest and easiest to comb after washing. The combing power of Comparative Example 4 (the group lacking camellia seed nourishment) increased sharply, significantly worse than the optimal Example 1, which strongly demonstrates that the camellia seed nourishing component is crucial for improving hair quality and reducing combing damage. At the same time, the combing power of Comparative Example 3 (the group lacking herbs) was also higher than that of Example 1, suggesting that the herbal compound extract also contributes to hair smoothness.

[0044] Regarding the product's mildness, in the chicken embryo chorioallantoic membrane experiment, all examples showed very low irritation scores, falling within the non-irritating range, demonstrating the excellent mildness of the formulation. However, Comparative Example 3 (herb-deficient group) exhibited significantly higher irritation than the examples, proving that the herbal compound extract plays a significant soothing and anti-irritant role in the formulation, and is one of the key factors for the product's high-temperature resistance. Most notably, Comparative Example 5 (traditional ZPT group) showed significant irritation, which not only highlights the overall mildness advantage of the formulation in this application but also reveals the strategy of combining piroctone olamine salt with natural extracts, effectively avoiding the irritation problems that may arise from traditional anti-dandruff agents (such as ZPT) while ensuring high efficacy.

[0045] Conclusion: Based on the combined data from the three experiments, the herbal decoction-based antibacterial shampoo described in this application successfully achieves the triple goals of powerful dandruff removal, hair smoothing, and extreme gentleness. Its core ingredients—pyrrolidone ethanolamine salt, herbal compound extracts, and camellia seed nourishing components—each perform key functions and work synergistically. The absence of any one ingredient would significantly reduce the product's performance in one or more aspects. Therefore, this original formula has a clear and verifiable comprehensive performance advantage compared to traditional anti-dandruff products and incomplete formulas.
