Description

Technical Field

[0001] This invention belongs to the field of daily chemical products technology, specifically relating to a hair care composition with quantifiable foam properties, combing properties, rheological properties and fragrance sensory properties as technical effects, including shampoo and conditioner and their preparation methods, all of which are derived from Chinese herbal extracts or natural plant-derived ingredients. Background Technology

[0002] Shampoo and conditioner are daily personal hygiene products. Consumers' demands for the user experience of hair care products have expanded from simple cleansing to sensory performance centered on quantifiable physical indicators, including the speed of lathering, the richness and fineness of the foam, the longevity and stability of the foam, the smoothness of combing wet and dry hair, the refreshing feeling after rinsing, the softness and volume of the hair after drying, and the naturalness and complexity of the fragrance.

[0003] Existing technologies include washing and care solutions that use synthetic surfactants, silicone oil conditioners, synthetic polymer thickeners, synthetic preservatives, and synthetic fragrances. However, all or part of the components of these solutions are not derived from natural plants, and they cannot meet the product positioning requirements of "all-plant-derived".

[0004] Existing technologies include shampoo and conditioner solutions that use natural saponin extracts as surfactants and are combined with some plant extracts. However, these solutions suffer from problems such as low foam height, insufficient foam stability, large bubble size, high resistance when combing wet hair, easy sedimentation and stratification of high amounts of plant extracts, and a lack of variety in fragrance.

[0005] Therefore, there is a need for a shampoo and conditioner composition and its preparation method that are quantifiable in terms of all components derived from herbal extracts or natural plant-derived ingredients, as well as in terms of foaming properties, combing properties, rheological properties, and fragrance sensory properties. Summary of the Invention

[0006] To address the limitations of existing technologies in terms of foaming, combing, rheology, and fragrance, this invention provides a fully plant-based shampoo and conditioner composition containing Gastrodia elata extract and its preparation method. Without using any chemically synthesized surfactants, silicone oils, synthetic conditioning agents, synthetic preservatives, or synthetic fragrances, quantifiable sensory performance is achieved through optimizing the compounding ratio of a triple natural saponin surfactant system, rheological design of a Bletilla striata gum natural thickening suspension system, construction of a natural phospholipid-plant oil conditioning system, and fragrance design of a three-stage natural fragrance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution.

[0008] A whole-plant-derived shampoo containing Gastrodia elata extract, wherein all components, by weight percentage, are derived from traditional Chinese medicine extracts or natural plant-derived ingredients, including: a natural saponin surfactant system (Sapindus mukorossi fruit extract 16.0%–24.0%, Camellia sinensis seed extract 5.0%–9.0%, Gleditsia sinensis extract 3.5%–8.0%); a natural thickening and suspending system (Bletilla striata gum 2.5%–4.0%, Dioscorea opposita polysaccharide extract 1.0%–2.0%); and a complex herbal extract system (Gastrodia elata extract 3.2%–4.5%, Platycladus orientalis leaf extract 3.0%–4.0%, Sophora flavescens extract 1.5%–2.5%, Phellodendron chinense extract 1.5%–2.5%, and processed Polygonum multiflorum). The extracts include 1.5%–2.5% Magnolia officinalis extract, 1.0%–2.0% Cnidium monnieri extract, 1.0%–2.0% Angelica sinensis extract, 1.2%–2.2% Eclipta prostrata extract, 0.0%–2.0% Lonicera japonica flower extract, and 0.8%–1.2% Anemarrhena asphodeloides extract; natural moisturizing and nourishing components (Aloe vera extract, Ganoderma lucidum extract, and Ganoderma lucidum extract); natural preservative components (Scutellaria baicalensis root extract, Paeonia suffruticosa root bark extract, and Clove bud extract); natural fragrance components (sweet orange peel oil, rosemary leaf oil, and peppermint leaf oil); and citric acid pH adjuster, with the pH controlled at 5.0–5.5.

[0009] A whole-plant-derived hair conditioner containing Gastrodia elata extract, by weight percentage, all components are derived from traditional Chinese medicine extracts or natural plant-derived ingredients, including: a natural emulsifying system composed of lecithin and astragalus gum; natural oils composed of tea seed oil and sesame oil; natural moisturizing components composed of aloe vera extract and Polygonatum sibiricum polysaccharide extract; a herbal conditioning system composed of extracts of Gastrodia elata, processed Polygonum multiflorum, Platycladus orientalis leaf, Phellodendron chinense, Eclipta prostrata, Ganoderma lucidum, Lonicera japonica flower, Angelica sinensis, and Sapindus mukorossi fruit; a natural preservation system composed of extracts of Scutellaria baicalensis root, Paeonia suffruticosa root bark, and Clove bud; and a natural fragrance system composed of sweet orange peel oil, rosemary leaf oil, and peppermint leaf oil, with a pH controlled at 4.5–5.0.

[0010] A shampoo and conditioner set consists of the aforementioned shampoo and conditioner. Both share a homologous extract system composed of extracts of Gastrodia elata, Platycladus orientalis leaves, processed Polygonum multiflorum, Phellodendron chinense, Eclipta prostrata, Lonicera japonica, Angelica sinensis, and Sapindus mukorossi fruit, as well as a homologous three-stage fragrance system, forming a pH gradient connection between the shampoo (pH 5.0–5.5) and the conditioner (pH 4.5–5.0).

[0011] The present invention also provides a cold-mixing preparation method for the above-mentioned shampoo and a hot-mixing emulsification preparation method for the conditioner, the process parameters of which are as described in the specific embodiments.

[0012] The shampoo formula of this invention is designed based on functional modular logic. Each component is modularly positioned according to its chemical composition and physical function. There are experimentally verified synergistic relationships between the six functional modules: Module 1: Foaming and Stabilizing Module (Triple Natural Saponin Surfactant System). Sapindus mukorossi fruit extract mainly contains triterpenoid saponins, tea seed extract mainly contains tea saponins, and soapberry extract mainly contains soapberry saponins. The differences in their molecular structures allow them to form a composite adsorption film at the gas-liquid interface: Sapindus mukorossi saponins have a strong ability to reduce surface tension, responsible for rapid foaming; tea saponins have a high resistance to liquid drainage at the interface, responsible for stabilizing the foam film; soapberry saponins, when combined with the other two, synergistically reduce the oil-water interfacial tension, responsible for increasing foam volume during kneading. The mass ratio of the three components was optimized through orthogonal experiments to (3.5–5):(1–1.6):(0.6–1.2), with an optimal ratio of 4:1.4:1. At this ratio, a dual-optimal balance is achieved between initial foam height and foam half-life.

[0013] Module Two: Conditioning and Smoothing Module. In the shampoo, the plant polysaccharides contained in aloe vera extract and reishi mushroom extract form a moisturizing adsorption film on the hair surface; the small molecule sugars and amino acid components in angelica extract and prepared he shou wu extract help improve the feel of wet hair. In the conditioner, lecithin forms a phospholipid bilayer structure that adsorbs onto the hair cuticle surface, tea seed oil and sesame oil provide a spreadable oil film, and astragalus gum enhances the even spreading of the cream on the hair strands, achieving a smooth feel without silicone oil through both physical lubrication and film isolation.

[0014] Module 3: Thickening and Suspension Module (Bletilla striata gum-yam polysaccharide system). Bletilla striata gum is a water-extracted, alcohol-precipitated polysaccharide gum from Bletilla striata tubers. Its polymer chains form a three-dimensional network in the saponin-water system, transforming the system from a near-Newtonian fluid to a pseudoplastic fluid. This rheological characteristic contributes to three benefits: high viscosity when standing and pouring, suspending a large number of herbal extract particles within the system without stratification; a sharp decrease in viscosity when kneading and applying, resulting in a smooth and non-sticky feel; and the Bletilla striata gum network slows down the drainage of foam film, extending the foam's half-life. Yam polysaccharides provide auxiliary thickening and moisturizing effects.

[0015] Module Four: Skin-Feeling Moisturizing Module. Aloe vera extract, Ganoderma lucidum extract, and Angelica sinensis extract in the shampoo together form water-soluble moisturizing components, enhancing the immediate moisturizing feel of the scalp and hair after washing.

[0016] Module Five: Fragrance Module (Three-Piece Natural Fragrance). Sweet orange peel oil, primarily containing limonene, is highly volatile and forms the top fruity note; rosemary leaf oil, primarily containing eucalyptol and borneol, forms the middle herbal note; peppermint leaf oil, primarily containing natural menthol, provides relatively long-lasting fragrance and a refreshing feel, forming the base note. This three-piece design gives the fragrance a discernible sense of depth and a longer sensory retention time.

[0017] Module Six: Preservation Module (Scutellaria baicalensis-Paeonia suffruticosa-Clove Triple Natural Preservation System). Scutellaria baicalensis root extract, Paeonia suffruticosa root bark extract, and clove bud extract constitute the product preservation system, used to ensure the product's microbiological quality during its shelf life, thus meeting product quality stability requirements without the use of any synthetic preservatives. This module only addresses the product's own preservation performance and does not relate to its effects on human use.

[0018] The compound herbal extracts are blended in a specific mass ratio, with Gastrodia elata extract being the most abundant. Its water-soluble polysaccharide component contributes positively to the moisturizing feel and viscoelasticity of the foam film. Each herbal extract is a standardized 10:1 concentrated water-alcohol extract, ensuring batch consistency and component traceability. Beneficial effects

[0019] Compared with the prior art, the present invention has the following beneficial effects: (1) Comprehensive quantification of sensory performance indicators. This invention establishes a complete sensory performance quantification system for all-plant-derived saponin-based hair care products: initial foam height ≥150 mm, foam half-life ≥180 s, average foam bubble size not greater than 80 μm, wet combing force reduction rate ≥35%, dry combing force reduction rate ≥30%, and hair surface friction coefficient reduction rate ≥30%. All of the above indicators can be reproduced according to national standard methods or general physical property testing methods.

[0020] (2) The triple saponin compound ratio breaks through the bottleneck of foam performance. The three saponins form a composite adsorption film at the gas-liquid interface, and the oil-water interfacial tension of the compound system is significantly lower than that of a single saponin or a combination of two; this synergistic effect cannot be predicted from the data of a single saponin. Based on this, the foam height is increased by about 46% compared with the single saponin system, the foam half-life is extended by about 59%, the average bubble size is significantly reduced, and the foam texture changes from coarse and weak bubbles to fine and dense bubbles.

[0021] (3) The rheological design of Bletilla striata gum simultaneously solves the problems of suspension, user experience and foam stability. Bletilla striata gum enables the system to obtain yield stress and typical shear thinning behavior, achieving a user experience of "no stratification when standing, smooth application and no residue after rinsing", and prolonging the foam half-life by delaying liquid film drainage.

[0022] (4) The smoothness of the silicone-free natural conditioning system has been quantitatively confirmed. The lecithin-tea seed oil-sesame oil-plant polysaccharide conditioning system achieved the set targets for wet combing power reduction, dry combing power reduction, hair surface friction coefficient reduction, and gloss improvement, which are close to commercially available silicone-containing synthetic systems under conditions that do not contain silicone oil or any synthetic cationic conditioning agents.

[0023] (5) The three-stage natural fragrance provides a layered olfactory experience. The fragrance structure of sweet orange top notes - rosemary middle notes - mint base notes has been verified by blind taste test. The fragrance is more natural, layered and has better after-wash fragrance perception than the single fragrance control. All fragrances are derived from natural plant essential oils.

[0024] (6) The set features a homologous design and pH gradient connection. The shampoo and conditioner share eight homologous extracts and a homologous three-stage fragrance, providing a consistent olfactory experience. The shampoo's pH of 5.0 to 5.5 and the conditioner's pH of 4.5 to 5.0 form a gradient connection, resulting in higher scores for smoothness, volume, and shine of the hair after drying compared to using the shampoo alone.

[0025] (7) All plant-based with zero synthetic additives. The entire formula contains no chemically synthesized surfactants, silicone oils, synthetic cationic conditioners, synthetic polymers, synthetic preservatives, synthetic fragrances, or polyethylene glycol derivatives. All components are traceable to traditional Chinese medicine or natural plant sources.

[0026] (8) Standardized extract compounding process ensures batch consistency. All herbal extracts in this invention are 10:1 standardized concentrated extracts with controllable index components. With clear process parameters for cold and hot emulsification, the product viscosity, pH and foaming performance have small batch-to-batch fluctuations, making it suitable for large-scale stable production.

Detailed Implementation

[0028] The present invention will be further described below with reference to embodiments, but the scope of protection of the present invention is not limited thereto. All herbal extracts are commercially available 10:1 concentrated water-alcohol extracts, meeting the requirements for inclusion in the "Catalogue of Used Cosmetic Ingredients". The total saponin content of the Sapindus mukorossi fruit extract is not less than 15% on a dry weight basis; the tea seed extract contains not less than 30% tea saponin on a dry weight basis; and the total saponin content of the Gleditsia sinensis extract is not less than 20% on a dry weight basis. Bletilla striata gum is a water-extracted, alcohol-precipitated polysaccharide gum from Bletilla striata tubers, with a content of not less than 55% based on Bletilla striata polysaccharides. Lecithin is a soybean-derived phospholipid. Citric acid is a natural citric acid source from Citrus medica fruit.

[0029] Based on a feed amount of 1000 g, according to Figure 3 Weigh out each component as shown in the formula, and refer to the preparation steps. Figure 1 Phase A: Add Bletilla striata gum to deionized water under low-speed stirring, disperse until no transparent particles remain, and let stand for at least 4 hours to swell until a semi-transparent viscous liquid is formed; add Dioscorea opposita polysaccharide extract and stir until completely dissolved to obtain a natural thickening base liquid. Phase B: Add Sapindus mukorossi fruit extract, tea seed extract, and Gleditsia sinensis extract in sequence, stirring until evenly dispersed after each addition, controlling the stirring speed below 200 rpm to avoid excessive air bubbles. Phase C: Premix the herbal extracts of Gastrodia elata, Platycladus orientalis leaf, Sophora flavescens, Phellodendron chinense, processed Polygonum multiflorum, Magnolia officinalis, Cnidium monnieri, Angelica sinensis, Eclipta prostrata, Lonicera japonica, and Anemarrhena asphodeloides evenly, and then slowly stir into the mixing bowl. Phase D: Add Aloe vera extract and Ganoderma lucidum extract, and stir until dissolved. Phase E: Mix sweet orange peel oil, rosemary leaf oil, and peppermint leaf oil, then add them to the mixture along with Scutellaria baicalensis root extract, Paeonia suffruticosa root bark extract, and Clove bud extract. Phase F: Add citric acid solution very slowly, measuring the pH while adding, and control it to around 5.3; let it stand for at least 2 hours to defoam, take samples for testing, and fill after stabilization.

[0030] The resulting shampoo was a brownish-brown, semi-transparent suspension with an apparent viscosity of 3620 mPa·s at 25°C, a pH of 5.3, an initial foam height of 158 mm, a foam half-life of 238 s, and an average bubble size of 62 μm.

[0031] Based on a feed amount of 1000 g, according to Figure 4 Weigh out each component as shown in the formula, and refer to the preparation steps. Figure 2Phase A: Mix deionized water, aloe vera extract, and polygonatum polysaccharide extract, and heat to 75°C. Phase B: Heat lecithin, tea seed oil, sesame oil, and astragalus gum to 75°C and stir until fully melted and homogeneous. Emulsification: Add Phase B to Phase A, homogenize at 3000 rpm for 4 minutes to form a fine paste, then stir and cool. Low-temperature activation: When the temperature drops to 45°C, add premixed herbal extracts of gastrodia elata, prepared he shou wu, arborvitae leaf, phellodendron bark, eclipta prostrata, ganoderma lucidum, honeysuckle flower, angelica sinensis, and soapberry fruit, and stir well. Fragrance: When the temperature drops to 40°C, add sweet orange peel oil, rosemary leaf oil, peppermint leaf oil, scutellaria baicalensis root extract, peony root bark extract, and clove bud extract, and stir well. Acidity adjustment and discharge: Adjust the pH to approximately 4.8 with citric acid solution, stir slowly, cool to room temperature, and age for at least 24 hours before bottling.

[0032] The resulting conditioner is a milky white to light brown paste with an apparent viscosity of approximately 9100 mPa·s at 25°C and a pH of 4.8.

[0033] After wetting your hair, take two pumps of shampoo (about 4 mL), lather it in your palms, and then apply it evenly to your scalp and hair. Massage in circular motions with your fingertips for 2-3 minutes. During this process, the foam remains rich and delicate and dissipates slowly, accompanied by a cooling sensation from the peppermint oil. Rinse thoroughly with warm water. Then, apply conditioner to your hair from the mid-lengths to the ends, leave it on for 1-2 minutes, and then rinse thoroughly. The shampooing process focuses on cleansing power and foam experience, while the conditioner process focuses on smoothness and long-lasting fragrance. Both processes share the same fragrance and blend naturally.

[0034] To verify the necessity of each functional module of the present invention and their synergistic relationship of physical properties, the following comparative examples were set up: Comparative Example 1 was a commercially available sulfate-based shampoo (containing SLES, silicone oil, and synthetic conditioning agents) and its matching conditioner, serving as a synthetic baseline control for sensory performance; Comparative Example 2 was the same formulation as Example 1, but the triple saponin system was replaced with a single Sapindus mukorossi fruit extract (equal saponin content), used to verify the synergistic effect of the triple saponin compound; Comparative Example 3 was the same formulation as Example 1, but the surfactants were replaced with potassium cocoyl glycinate, sodium lauroyl glutamate, and... A synthetic amino acid system containing cocamidopropyl betaine and decyl glucoside (equal active ingredient content) was used, with the thickening system replaced by a synthetic acrylic (ester) copolymer (equal viscosity), and a matching synthetic conditioner was added to compare the performance differences between the natural and synthetic systems. Comparative Example 4 was the same formulation as Example 1 but without Bletilla striata gum (replaced with an equal amount of water) to verify the necessity of the Bletilla striata gum thickening suspension module. Comparative Example 5 was the same formulation as Example 1 but the fragrance was replaced with a single peppermint leaf oil (total amount unchanged) as a single fragrance control for the three-stage fragrance.

[0035] The initial foam height was determined using a Roche foam analyzer according to GB / T 7462-1994. The foam half-life was the time required for the foam height to drop to half of its initial height. The average bubble size was determined using high-speed imaging and image analysis (samples were taken 30 seconds after foaming, and the average equivalent circle diameter of at least 500 bubbles was statistically analyzed). The foaming time was the time required for the foam to reach 90% of its maximum height under standard kneading conditions. The test temperature was 25℃, and the water hardness was 150 mg / kg. The test results are shown below. Figure 5 .

[0036] The results showed that the initial foam height (158 mm), foam half-life (238 s), and average bubble size (62 μm) of Example 1 were all superior to the single saponin system (Comparative Example 2: 108 mm, 150 s, 122 μm) and the system without Bletilla striata gum (Comparative Example 4: 132 mm, 165 s, 95 μm), and were at the same energy level as the synthetic system. The foam data of Comparative Example 5 were basically consistent with those of Example 1, indicating that the fragrance component had no effect on the foam performance, and the improvement in foam performance was attributed to the synergy between the triple saponin system and the Bletilla striata gum thickening system.

[0037] An L9(3^4) orthogonal experimental design was adopted, using initial foam height as the evaluation index, to investigate the effects of three levels on four factors: the mass ratio of Sapindus mukorossi fruit extract to tea seed extract (A), the amount of Gleditsia sinensis extract (B), the amount of Gastrodia elata extract (C), and the amount of Bletilla striata gum (D). Each experiment was repeated three times, and the results were averaged. The factor level table is shown below. Figure 6 The experimental design and results are shown in [link to experimental design]. Figure 7 The results of the range and variance analysis are shown in [the table]. Figure 8 .

[0038] The results showed that the saponin mass ratio (A) had a significant impact on foam height (P<0.05), with the optimal level being A2, i.e., Sapindus mukorossi:Tea seed = 4:1.4. The amounts of Gleditsia sinensis, Gastrodia elata, and Bletilla striata gum all made positive contributions. The optimal combination A2B2C2D2 was consistent with the ratio in Example 1, and its foam height and half-life reached the optimal equilibrium point of the full factorial experiment, significantly higher than the expected value of the simple superposition of the optimal levels of a single factor. This proves that there is a synergistic effect of physical properties among the modules, rather than an additive effect of independent contributions.

[0039] Shear rate-viscosity curves (0.01–100 s⁻¹), yield stress (stress scan mode), thixotropic ring area, and viscosity recovery rate (the percentage of viscosity recovering to low shear viscosity 60 s after high shear cessation) were measured using a rotational rheometer. The results are shown in [Figure number missing]. Figure 9 .

[0040] The results showed that Bletilla striata gum transformed the saponin system from a near-Newtonian fluid to a typical pseudoplastic fluid, with the power law exponent n decreasing from 0.78 to 0.30 and the yield stress increasing from 1.5 Pa to 9.2 Pa, which was sufficient to suspend a large number of herbal extract particles in the system. No stratification or sedimentation occurred after standing for 3 months. The shear thinning ratio, viscosity recovery rate, and thixotropic ring area of ​​Example 1 were all superior to the system without Bletilla striata gum and the single saponin system, meeting the usage requirements of "hanging on the wall when poured, smooth when kneaded, and refreshing when rinsed", and contributing to the stability of the foam liquid film.

[0041] The interfacial tension of each saponin combination on soybean oil-water at a concentration of 0.5% was determined using the hanging drop method at a test temperature of 25℃. The results are shown below. Figure 10 .

[0042] The results showed that the interfacial tension of the triple saponin compound system (Sapindus mukorossi:tea:Gleditsia sinensis = 4:1.4:1) was significantly lower than that of any single saponin or any combination of two, indicating that the three saponin molecules produced a non-additive synergistic tension-reducing effect by forming a mixed adsorption film at the interface. This effect could not be linearly predicted from the interfacial tension data of a single saponin, and the optimal mass ratio could not be obtained by theoretical calculation; it could only be determined experimentally.

[0043] The wet and dry combing forces of hair bundles were measured using a texture analyzer; the surface friction coefficient of hair strands was calculated using a hair slip friction test; and the surface gloss of hair strands was measured using a gloss meter (60° incident angle). Healthy women's long hair (40 cm in length, 5 g per bundle) was washed, conditioned, and blow-dried according to the prescribed method before testing. The "Example 3 Kit" is a treatment plan that combines washing with the shampoo of Example 1 with the application of the conditioner of Example 2. The test results are shown below. Figure 11 .

[0044] The results showed that the wet combing force reduction rate of the Example 3 kit was 41.2%, the dry combing force reduction rate was 34.6%, the friction coefficient reduction rate was 35.8%, and the gloss improvement rate was 30.6%, all of which met the limits of claim 6. The performance gap with the silicone oil-containing synthetic kit (Comparative Example 1) was minimized. Even when using a homologous conditioner, the wet combing force reduction rate of the single saponin system (Comparative Example 2) was lower than that of the Example 3 kit, indicating that the triple saponin composite adsorption film itself is a component of hair surface conditioning. The wet combing force reduction rate of Example 1 used alone was significantly lower than that of the kit, proving the necessity of the synergistic conditioning performance of the shampoo-conditioner two-step system and the homologous design of the kit.

[0045] Twenty trained evaluators conducted blind tests on the shampoo of Example 1, the conditioner of Example 2, Comparative Example 1, and Comparative Example 5, evaluating the naturalness and complexity of the fragrance, the perceived 2-hour scent retention, and overall preference on a scale of 0 to 10. The evaluation results are shown below. Figure 12 .

[0046] The results showed that the three-stage fragrance had significant advantages in terms of layering. The layering, fragrance retention, and overall liking of Example 1 were all better than the single-fragrance control (Comparative Example 5); the fragrance naturalness was better than the synthetic fragrance system (Comparative Example 1); the fragrance retention score of the conditioner in Example 2 was slightly higher than that of the shampoo in Example 1. The homologous fragrance made the olfactory experience of shampooing and conditioning a smooth progression.

[0047] Thirty evaluators conducted a blind tasting with half-head control, evaluating seven indicators on a scale of 0 to 10: ease of lathering, foam texture, feel of wet hair, ease of rinsing, clean feeling after rinsing, softness after drying, and fluffiness after drying. The evaluation results are shown below. Figure 13 .

[0048] The results showed that the overall skin feel of the Example 3 kit reached and slightly exceeded that of the synthetic system, with a total score of 61.0 points across seven items, which was better than the SLES synthetic kit and the synthetic amino acid kit. Among them, the refreshing feeling after rinsing and the fluffiness after drying were better than the synthetic control, which was due to the high viscosity recovery rate of Bletilla striata gum, resulting in less residue after rinsing, and the silicone oil-free formula, which avoided the flattening caused by silicone oil accumulation. The skin feel scores of the single saponin system (Comparative Example 2) and the Bletilla striata gum-free system (Comparative Example 4) were significantly lower than those of the Example 3 kit, which directly demonstrated the technical value of the triple saponin compound and the Bletilla striata gum module.

[0049] The samples from Examples 1 and 2, and Comparative Examples 1, 2, and 4 were subjected to five cycles of thermal cycling at 45℃ for 30 days, -10℃ for 24 hours to 40℃ for 24 hours, centrifugation at 3000 rpm for 30 minutes, and at room temperature for 3 months. Changes in appearance, pH, apparent viscosity, and initial foam height were measured. The results are shown in […]. Figure 14 .

[0050] The results showed that after various accelerated stability tests, Examples 1 and 2 maintained a foam height retention rate of ≥98.2%, a viscosity change rate of ≤1.2%, and a pH change of ≤0.1, with no stratification, precipitation, or discoloration. Their stability reached or was even slightly better than that of the SLES synthesis system. Comparative Example 4 (without Bletilla striata gum) showed obvious stratification after 3 months at room temperature and during centrifugation, with a viscosity loss of 12.4% and a foam height retention rate of 88.5%, verifying the decisive contribution of the three-dimensional network of Bletilla striata gum to the physical stability of the system. Comparative Example 2 (single saponin) showed slight sedimentation and a decrease in viscosity, indicating that the triple saponin combination also improved the colloidal stability of the system.

[0051] Following the preservative challenge test method in the "Cosmetic Safety Technical Specifications," a mixed challenge bacteria (bacteria and fungi) was inoculated into the shampoo of Example 1 and a blank control (same formula as Example 1, but without Scutellaria baicalensis root extract, Paeonia suffruticosa root bark extract, and Clove bud extract, replaced with an equal volume of water). The number of surviving bacteria was measured on days 7, 14, 21, and 28. The results are shown below. Figure 15 .

[0052] The results showed that the triple natural preservation system of Scutellaria baicalensis root-Paeonia suffruticosa root bark-Syzygium aromaticum buds could reduce the challenge bacteria recovery count to <10 CFU / g on day 7, meeting the qualified standard of the preservation challenge test and ensuring the shelf-life quality of the product under the condition of no synthetic preservatives. The bacterial recovery count of the blank control group decreased by only about 1.5 logs on day 7, and rebounded significantly from day 14, returning to the initial inoculation level on day 28, which was judged as unqualified. This proves that the product's own preservation performance is entirely due to the contribution of the triple natural preservation system.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
