Description

Technical Field

[0001] This application relates to the technical field of shampoo and conditioner raw materials, and in particular to an oil-controlling and fluffy shampoo and conditioner raw material based on ginsenosides and its preparation method. Background Technology

[0002] With the increasing demand for scalp care, long-lasting oil control, sustained volumizing, and gentle repair have become the core research and development directions for shampoo and conditioner products. However, existing oil-controlling and volumizing shampoo and conditioner formulas for oily scalps and fine, limp hair still have many shortcomings, making it difficult to simultaneously achieve oil control, volumizing, and conditioning effects, resulting in poor overall performance.

[0003] First, most products on the market use strong cleansing systems such as sulfates and soap bases, which can only physically remove surface oils from the scalp and cannot regulate sebum secretion at its source. This strong degreasing effect can damage the scalp barrier, causing an imbalance of oil and water, leading to compensatory oil production. Some products add common plant extracts to control oil, but the proportions are arbitrary, the effective content is low, the synergy is poor, and the oil-controlling effect is weak and unstable.

[0004] Secondly, conventional volumizing formulas often use silicone oil or ordinary cationic polymers. Although they can achieve instant volume, silicone oil tends to accumulate and remain on the scalp and hair surface, absorbing oil and dust, causing the hair roots to collapse quickly. Long-term use can easily lead to heavy, frizzy hair and clogged pores.

[0005] Furthermore, high-cleansing and oil-controlling systems are relatively irritating, and long-term use can easily lead to scalp redness, itching, and sensitivity, disrupting the scalp's microecological balance. If only moisturizing and soothing ingredients are added, there are issues with poor compatibility and unscientific formulation among the components, which can easily result in system layering, uneven dispersion of active ingredients, and inactivation of effective ingredients, leading to poor product stability and significant reduction in efficacy.

[0006] Application content

[0007] This application aims to address, at least to some extent, the technical problems in the related art.

[0008] To achieve the above objectives, this application proposes an oil-controlling and volumizing shampoo and conditioner raw material based on ginsenosides, comprising the following components by weight: 3-12 parts of ginsenoside compound extract, 2-8 parts of plant oil-controlling compound ingredients, 1-5 parts of hair volumizing conditioner, 0.5-3 parts of moisturizing and soothing agent, and 72-92 parts of solvent.

[0009] The ginsenoside compound extract is a mixture of total ginsenosides, ginsenoside Rg3, ginsenoside Rh2, and ginsenoside Rd; the plant oil-controlling compound is a mixture of rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract in a specific mass ratio; and the hair volumizing conditioner is one or a combination of two of polyquaternium-73 and guar hydroxypropyltrimethylammonium chloride.

[0010] Specifically, in the ginsenoside compound extract, the mass ratio of total ginsenosides, ginsenoside Rg3, ginsenoside Rh2, and ginsenoside Rd is (5-8):(1-2):(0.5-1):(0.5-1).

[0011] Specifically, in the plant-based oil-controlling compound ingredients, the mass ratio of rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract is (3-5):(2-3):(1-2).

[0012] Specifically, the moisturizing and soothing agent is any one or more of panthenol, allantoin, and β-glucan; the solvent is one or more of deionized water, glycerin, and propylene glycol.

[0013] Specifically, by weight, it includes the following components: 8 parts ginsenoside compound extract, 5 parts plant oil-controlling compound ingredients, 3 parts hair volumizing conditioner, 1.5 parts moisturizing and soothing agent, and 82.5 parts solvent.

[0014] Specifically, by weight, it also includes 0.1-0.8 parts of preservative, wherein the preservative is one or more of phenoxyethanol, ethylhexylglycerin, and p-hydroxyacetophenone.

[0015] Specifically, by weight, it also includes 0.05-0.3 parts of a chelating agent, wherein the chelating agent is one or more combinations of disodium EDTA, tetrasodium EDTA, and sodium phytate.

[0016] The preparation method of ginsenoside-based oil-controlling and volumizing shampoo and conditioner raw materials includes the following steps:

[0017] S1. Accurately weigh each component raw material according to the preset weight ratio. Store the ginsenoside compound extract and plant oil-controlling compound ingredients in a dry, airtight container away from light for later use. Remove impurities, lumps and agglomerates from the solid raw materials by sieving or manual processing to ensure that the powder is uniform and free of foreign matter. Check that the liquid raw materials are free of turbidity, sedimentation and stratification for later use.

[0018] S2. Add the specified amount of solvent to the reaction vessel equipped with temperature-controlled stirring, heat it to 40-50℃ at a uniform rate, set the stirring speed to 300-400r / min, and stir at a constant temperature for 5-10min to make the temperature and concentration of the solvent system uniform and stable, thus completing the substrate pretreatment.

[0019] S3. Maintain the reaction vessel at 40-50℃ and the stirring speed at 300-400r / min. Add the ginsenoside compound extract evenly to the system in 2-3 portions, with an interval of 3-5 minutes between each addition. After each addition, keep the mixture warm and stir for 15-20 minutes until completely dissolved. Then add the plant oil-controlling compound ingredients, raise the temperature to 55-60℃, adjust the stirring speed to 450-550r / min, and stir at a constant temperature for 20-25 minutes to fully disperse and blend the various active ingredients, thus obtaining the compound efficacy mother liquor.

[0020] S4. After the mother liquor is prepared, stop heating and cool down to 30-35℃ at a constant speed and keep the temperature constant. Reduce the stirring speed to 200-250r / min and add the hair fluffing conditioner and moisturizing soothing agent in sequence. After all the additions are completed, stir at a low speed and constant temperature for 10-15min to make the components evenly dispersed and obtain the initial mixed raw material solution.

[0021] S5. Transfer the initial mixture to a high-pressure homogenizer and homogenize it at 25-35MPa for 8-12 minutes to ensure uniform dispersion of the system components. Then, filter the mixture using a 200-300 mesh filter cloth to remove trace amounts of insoluble impurities. After filtration, seal the liquid and allow it to cool naturally to room temperature to obtain the finished washing and care raw material.

[0022] Specifically, in step S3, the ginsenoside compound extract is added in batches, in 2-3 even additions, with an interval of 3-5 minutes between each addition.

[0023] The beneficial effects of the ginsenoside-based oil-controlling and volumizing shampoo and conditioner raw material and its preparation method are as follows:

[0024] 1. It uses a compound extract of ginseng total saponins, combined with a scientifically formulated blend of rosemary, arborvitae leaf, and scutellaria baicalensis oil-controlling components. It can regulate the metabolism of scalp sebaceous glands from the root, inhibit excessive oil secretion, and the multi-component active ingredients work synergistically to stabilize the water-oil balance of the scalp, repair the scalp barrier, and avoid compensatory oil production caused by strong degreasing.

[0025] 2. Polyquaternium-73 and guar hydroxypropyltrimethylammonium chloride are selected as volumizing conditioners, which can form a thin and breathable protective film on the hair surface, providing long-lasting support for the hair roots. These components leave no heavy residue and do not easily absorb oil and dust, keeping the hair roots clean and upright for a long time, effectively improving the problems of thick, frizzy, flat, and clogged pores caused by traditional formulas.

[0026] 3. It contains no harsh cleansing ingredients, and is formulated with soothing and moisturizing ingredients such as panthenol, allantoin, and beta-glucan, which can effectively improve scalp redness, itching, and sensitivity, repair the scalp microecology, and ensure good compatibility of the various functional components without ingredient antagonism or activity inactivation. Combined with a refined process of segmented temperature control, batch feeding, and low-pressure homogenization, it effectively avoids efficacy decay and significantly improves storage stability. Attached Figure Description

[0027] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein:

[0028] Figure 1 This is a flowchart illustrating the oil-controlling and volumizing shampoo and conditioner raw material based on ginsenosides and its preparation method, as described in this application. Detailed Implementation

[0029] To make the technical means, inventive features, objectives, and effects of this application easier to understand, the application is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] The present application will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the ginsenoside-based oil-controlling and volumizing shampoo and conditioner raw material of this application embodiment includes the following components by weight: 3-12 parts of ginsenoside compound extract, 2-8 parts of plant oil-controlling compound ingredients, 1-5 parts of hair volumizing conditioner, 0.5-3 parts of moisturizing and soothing agent, and 72-92 parts of solvent.

[0032] Among them, the ginsenoside compound extract is a mixture of total ginsenosides, ginsenoside Rg3, ginsenoside Rh2 and ginsenoside Rd; the plant oil-controlling compound is a mixture of rosemary extract, arborvitae leaf extract and scutellaria baicalensis extract in a specific mass ratio; the hair volumizing conditioner is one or a combination of two of polyquaternium-73 and guar hydroxypropyltrimethylammonium chloride.

[0033] It should be noted that the ginsenoside compound extract is a mixture of total ginsenosides, ginsenoside Rg3, ginsenoside Rh2, and ginsenoside Rd. The four saponin components work synergistically to overcome the limitations of single ginsenoside efficacy and improve scalp oiliness and hair root collapse from multiple dimensions such as scalp texture, sebum secretion, and hair follicle care.

[0034] The plant-based oil-controlling compound is made from rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract in a specific mass ratio. The natural plant ingredients gently regulate scalp sebum secretion without the dryness or irritation of chemical oil-controlling ingredients, while also taking care of scalp health.

[0035] The hair volumizing conditioner is one or a combination of two of polyquaternium-73 and guar hydroxypropyltrimethylammonium chloride. It can be precisely adhered to the hair surface and roots to improve the problems of flat, dry and frizzy hair, build a volumizing support film, and maintain the volumizing state of the hairstyle for a long time.

[0036] In one embodiment of this application, the mass ratio of total ginsenosides, ginsenoside Rg3, ginsenoside Rh2, and ginsenoside Rd in the ginsenoside compound extract is (5-8):(1-2):(0.5-1):(0.5-1).

[0037] It should be noted that this formula represents the optimal blend ratio. Ginsenosides, as the core base ingredient, play a fundamental role in scalp repair and regulating scalp metabolism. Ginsenoside Rg3 effectively inhibits overactive sebaceous glands, reducing excessive sebum secretion and addressing oily scalp issues at their root. Ginsenoside Rh2 possesses excellent scalp barrier repair capabilities, alleviating barrier damage, redness, and itching caused by frequent oil production and cleaning in oily scalps. Ginsenoside Rd nourishes hair follicles, strengthens hair root support, and reduces the weakness and flatness of fine hair roots. The synergistic combination of these four ingredients achieves a three-in-one effect of oil control, repair, and hair nourishment.

[0038] In one embodiment of this application, the mass ratio of rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract in the plant-based oil-controlling compound is (3-5):(2-3):(1-2).

[0039] It should be noted that in the plant-based oil-controlling compound ingredients, the mass ratio of rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract is (3-5):(2-3):(1-2). Rosemary extract is the core oil-controlling ingredient, which can regulate the scalp's water-oil balance, shrink scalp pores, reduce sebum secretion, and also has antibacterial and refreshing effects, improving problems such as oily scalp, itchiness, and dandruff. Arborvitae leaf extract is a traditional hair-nourishing ingredient that can nourish the scalp, strengthen hair roots, and alleviate hair loss and breakage problems associated with oiliness. Scutellaria baicalensis extract is rich in flavonoid active ingredients, which have anti-inflammatory, soothing, and antioxidant effects, can neutralize free radicals on the scalp, and alleviate inflammatory reactions in oily scalps. The combination of these three ingredients takes into account oil control, soothing, and hair nourishment, making it suitable for use on sensitive oily scalps.

[0040] In one embodiment of this application, the moisturizing and soothing agent is any one or more of panthenol, allantoin, and β-glucan; the solvent is one or more of deionized water, glycerin, and propylene glycol.

[0041] It should be noted that panthenol can penetrate deep into the hair cuticle to replenish moisture, repair damaged hair, and improve the dryness caused by oil-controlling ingredients; allantoin gently soothes scalp redness and stinging, and repairs the fragile scalp barrier; beta-glucan can enhance scalp immunity and increase scalp tolerance. All three can be used alone or in combination to achieve refreshing, moisturizing, soothing, and stabilizing effects, solving the common problems of dryness and irritation in oil-controlling shampoos and conditioners.

[0042] The solvent is one or more mixed solvents selected from deionized water, glycerin, and propylene glycol. Deionized water serves as the basic dispersion medium, free from impurities and ion interference, ensuring the stability of the raw material system. Glycerin and propylene glycol are polyol moisturizing solvents, which not only enhance the solubility of various functional ingredients but also assist in moisturizing and locking in moisture, preventing the raw material system from drying and clumping, while improving the gentle and smooth feel of the finished washing and care raw materials.

[0043] Example 1

[0044] The ginsenoside-based oil-controlling and volumizing shampoo and conditioner contains the following components by weight: 3 parts ginsenoside compound extract, 2 parts plant oil-controlling compound ingredients, 1 part hair volumizing conditioner, 0.5 parts moisturizing and soothing agent, 0.1 parts preservative, 0.05 parts chelating agent, and 92 parts solvent.

[0045] The ginsenoside compound extract contains total ginsenosides, ginsenoside Rg3, ginsenoside Rh2, and ginsenoside Rd in a mass ratio of 5:1:0.5:0.5; the plant oil-controlling compound ingredients contain rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract in a mass ratio of 3:2:1; the hair volumizing conditioner is polyquaternium-73; the moisturizing and soothing agent is panthenol; the preservative is p-hydroxyacetophenone; the chelating agent is disodium EDTA; and the solvent is deionized water.

[0046] Example 2

[0047] The ginsenoside-based oil-controlling and volumizing shampoo and conditioner contains the following components by weight: 8 parts ginsenoside compound extract, 5 parts plant oil-controlling compound ingredients, 3 parts hair volumizing conditioner, 1.5 parts moisturizing and soothing agent, 0.4 parts preservative, 0.15 parts chelating agent, and 82.5 parts solvent.

[0048] The ginsenoside complex extract contains total ginsenosides, ginsenoside Rg3, ginsenoside Rh2, and ginsenoside Rd in a mass ratio of 6.5:1.5:0.8:0.8; the plant oil-controlling compound contains rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract in a mass ratio of 4:2.5:1.5; the hair volumizing conditioner is a mixture of polyquaternium-73 and guar gum hydroxypropyltrimethylammonium chloride in equal mass; the moisturizing and soothing agent is a mixture of panthenol and allantoin in a 1:1 mass ratio; the preservative is a mixture of phenoxyethanol and ethylhexylglycerin in a 2:1 mass ratio; the chelating agent is sodium phytate; and the solvent is a mixture of deionized water, glycerin, and propylene glycol in an 8:1:1 mass ratio.

[0049] Example 3

[0050] The ginsenoside-based oil-controlling and volumizing shampoo and conditioner contains the following components by weight: 12 parts ginsenoside compound extract, 8 parts plant oil-controlling compound ingredients, 5 parts hair volumizing conditioner, 3 parts moisturizing and soothing agent, 0.8 parts preservative, 0.3 parts chelating agent, and 72 parts solvent.

[0051] The ginsenoside compound extract contains total ginsenosides, ginsenoside Rg3, ginsenoside Rh2, and ginsenoside Rd in a mass ratio of 8:2:1:1; the plant oil-controlling compound ingredients contain rosemary extract, arborvitae leaf extract, and scutellaria baicalensis extract in a mass ratio of 5:3:2; the hair volumizing conditioner is guar gum hydroxypropyltrimethylammonium chloride; the moisturizing and soothing agent is panthenol, allantoin, and β-glucan in a mass ratio of 1:1:1; the preservative is phenoxyethanol; the chelating agent is tetrasodium EDTA; and the solvent is a mixture of glycerin and propylene glycol in a mass ratio of 1:1.

[0052] It should be noted that Example 1 has the lowest total active ingredient content and the highest solvent content (92 parts); all functional components are added in the minimum amount, the system formula uses only a single raw material, there is no compound combination, the formula is extremely simple, the cost is lower, and it is suitable for mild oil control and daily basic washing and care products.

[0053] Example 2: The amount of each active ingredient added is moderate, and the solvent is reduced to 82.5 parts; binary compound raw materials (volume conditioner, moisturizing and soothing agent, preservative, solvent) are used in many places, and the chelating agent is replaced with sodium phytate, which takes into account both oil control and volume and gentle soothing, and is suitable for mid-range oil control shampoos and scalp essences.

[0054] Example 3: The addition of ginsenosides, plant-based oil-controlling, volume-enhancing, moisturizing and soothing active ingredients reached its peak, with only 72 parts of solvent; the moisturizing and soothing uses a ternary compound, with no deionized water in the solvent, only glycerol and propylene glycol, and the chelating agent was replaced with tetrasodium EDTA, which has a strong oil-controlling and repairing effect and is suitable for heavy oily scalp and seborrheic scalp.

[0055] In summary, Example 2 balances gentleness, oil control, volume, and repair, meeting the core needs of daily care for normal hair and oil control and volume for mild to moderate oily hair. It is suitable for the mainstream market of mid-range functional and mass-market consumer shampoos and conditioners, and can be mass-produced.

[0056] In one embodiment of this application, the product further includes 0.1-0.8 parts by weight of a preservative, which is one or more combinations of phenoxyethanol, ethylhexylglycerin, and p-hydroxyacetophenone.

[0057] It should be noted that this raw material also includes 0.1-0.8 parts by weight of preservatives, which are one or more combinations of phenoxyethanol, ethylhexylglycerin, and p-hydroxyacetophenone. These preservatives are mild, specifically designed for personal care products; they are low-irritant and have broad-spectrum antibacterial properties, effectively inhibiting the growth of bacteria and mold within the raw material system, extending the product's shelf life, while not damaging the structure and efficacy of active ingredients such as ginsenosides and plant extracts.

[0058] In one embodiment of this application, the chelating agent is further comprising 0.05-0.3 parts by weight, wherein the chelating agent is one or more combinations of disodium EDTA, tetrasodium EDTA, and sodium phytate.

[0059] It should be noted that chelating agents can complex trace amounts of metal ions in solvents and raw materials, effectively avoiding problems such as raw material oxidation, discoloration, active ingredient failure, and system turbidity and stratification caused by metal ions. This significantly improves the storage stability and weather resistance of washing and care raw materials, ensuring that the product's efficacy does not diminish and its appearance does not deteriorate after long-term storage.

[0060] The preparation method of ginsenoside-based oil-controlling and volumizing shampoo and conditioner raw materials includes the following steps:

[0061] S1. Accurately weigh each component raw material according to the preset weight ratio. Store the ginsenoside compound extract and plant oil-controlling compound ingredients in a dry, airtight container away from light for later use. Remove impurities, lumps, and agglomerates from the solid raw materials by sieving or manual processing to ensure that the powder is uniform and free of foreign matter. Check that the liquid raw materials are free of turbidity, sedimentation, and stratification for later use.

[0062] It should be noted that the efficacy threshold of raw materials for shampoos and conditioners is narrow. The amount of ginsenosides and plant oil-controlling ingredients added directly determines the oil-controlling and volumizing effects. Deviations in the ratio can lead to insufficient oil control, dry scalp, and sedimentation and stratification. Quantitative weighing ensures the balance of the formula system.

[0063] Ginsenosides are polyphenolic saponins, which are easily oxidized and degraded when exposed to light and high humidity, losing their oil-controlling and repairing activities. Most plant oil-controlling flavonoids and polyphenol extracts are also photosensitive. Sealing and drying isolates oxygen, water vapor, and ultraviolet rays to lock in the biological activity of the raw materials.

[0064] Agglomeration of powder raw materials is caused by particle agglomeration and moisture absorption. Large particles cannot be completely dissolved in the subsequent process, resulting in white spots, sedimentation, and incomplete homogenization in the liquid. Screening breaks up agglomerated particles, reduces particle size, and improves the subsequent dissolution rate and dispersion uniformity.

[0065] If liquid functional additives become cloudy, separate into layers, or precipitate, it indicates that the additives have been hydrolyzed, emulsified, and ineffective. Mixing them into the system will disrupt the overall stability. Therefore, it is important to remove deteriorated raw materials in advance to avoid the risk of layering and deterioration in the finished product.

[0066] S2. Add the specified amount of solvent to the reaction vessel equipped with temperature-controlled stirring, heat it to 40-50℃ at a uniform rate, set the stirring speed to 300-400r / min, and stir at a constant temperature for 5-10min to make the temperature and concentration of the solvent system uniform and stable, thus completing the substrate pretreatment.

[0067] It should be noted that commonly used alcohols and polyols in washing and conditioning products have high viscosity at low temperatures and slow molecular movement. Heating reduces the viscosity of the solvent, improves the fluidity and solubility of the solvent molecules, and provides a good dissolving medium for saponins and plant extracts.

[0068] Stir at a medium speed of 300-400 r / min at a constant temperature for 5-10 min: Eliminate local temperature and concentration differences within the reactor, and avoid localized excessive concentration / diluteness of the solvent in the low-temperature zone of the reactor wall; form a uniform and continuous solvent base to prevent saponin precipitation and clumping due to sudden localized high concentrations after subsequent feeding.

[0069] By standardizing the physicochemical environment (temperature, viscosity, polarity) of the solvent system in advance, the impact on the system when adding functional ingredients is reduced, and the risk of active substance precipitation is lowered.

[0070] S3. Maintain the reactor at 40-50℃ and the stirring speed at 300-400r / min. Add the ginsenoside compound extract evenly to the system in 2-3 portions, with an interval of 3-5 minutes between each addition. After each addition, keep the mixture warm and stir for 15-20 minutes until completely dissolved. Then add the plant oil-controlling compound ingredients, raise the temperature to 55-60℃, adjust the stirring speed to 450-550r / min, and stir at a constant temperature for 20-25 minutes to fully disperse and blend the various functional components, thus obtaining the compound efficacy mother liquor.

[0071] It should be noted that ginsenosides have moderate water solubility. Adding a large amount of ginsenosides to the solvent at once will cause instantaneous local saturation, resulting in rapid precipitation and the formation of colloidal agglomerates that cannot be completely dissolved. Adding small amounts of ginsenosides multiple times allows sufficient time for the ginsenosides to diffuse and dissolve, maintaining an unsaturated dissolution state in the system and achieving complete dissolution.

[0072] Saponin molecules are fully bonded to solvent molecules by hydrogen bonds. After stirring at a constant temperature for 15-20 minutes, the intermolecular association of saponins is broken, and they are completely dissociated into a single molecule dispersed state, thus fully releasing their oil-controlling and scalp barrier-repairing activities.

[0073] Plant-based oil-controlling components (such as flavonoids and tannins from arborvitae, witch hazel, and green tea extracts) have greater solubility resistance than ginsenosides. Appropriate heating further reduces the viscosity of the system and increases the solubility of plant polyphenols; at the same time, it promotes the compatibility between saponins and plant-based oil-controlling components, forming a synergistic compound system.

[0074] High-shear stirring breaks down the local aggregation of the two functional molecules, allowing the two active ingredients, ginsenoside for oil control and repair, and plant extracts for lipid inhibition and oil control, to be evenly dispersed and intermingled, constructing a synergistic oil-controlling mother liquor system; high temperature and high shear eliminate local high-concentration areas, avoiding the mutual flocculation and precipitation of polyphenols and saponins.

[0075] First, dissolve the less stable ginsenosides, then combine them with plant oil-controlling ingredients. This step-by-step dissolution avoids phase separation caused by direct mixing of the two types of active ingredients, thus building a stable and effective mother liquor in advance.

[0076] S4. After the mother liquor is prepared, stop heating and cool down to 30-35℃ at a constant speed and keep the temperature constant. Reduce the stirring speed to 200-250r / min, and add the hair fluffing conditioner and moisturizing soothing agent in sequence. After all the ingredients are added, stir at a low speed and constant temperature for 10-15min to make the components evenly dispersed and obtain the initial mixed raw material solution.

[0077] It should be noted that hair volumizing agents are mostly cationic conditioning polymers and quaternary ammonium salts, while moisturizing and soothing agents are mostly panthenol, betaine, and plant polysaccharides. High temperatures (above 55°C) will destroy the molecular structure of cationic conditioning agents, leading to a decrease in volumizing and smoothing properties. They will also cause polysaccharide soothing agents to be hydrolyzed and deactivated at high temperatures, thus reducing their cooling, protective, conditioning, and soothing functions.

[0078] Reduce the stirring speed to 200-250 r / min. Cationic conditioning polymers are long-chain macromolecules. High-speed stirring and strong shearing will break the long molecular chains, reducing the effect of adsorbing hair strands and making hair roots fluffy. Gentle stirring at low speed can only achieve uniform mixing, retain the complete molecular structure of the conditioning agent, and maintain the fluffy, smooth and anti-static ability.

[0079] Stir at low speed and constant temperature for 10-15 minutes to gently disperse the macromolecular conditioning agents and prevent the polymers from tangling and clumping; at the same time, it allows the soothing and moisturizing ingredients to be evenly dispersed, neutralizes the slight irritation of saponins, balances the skin feel of the system, and obtains a stable initial mixture.

[0080] S5. Transfer the initial mixture to a high-pressure homogenizer and homogenize it at 25-35MPa for 8-12 minutes to ensure uniform dispersion of the system components. Then, filter the mixture using a 200-300 mesh filter cloth to remove trace amounts of insoluble impurities. After filtration, seal the liquid and allow it to cool naturally to room temperature to obtain the finished washing and care raw material.

[0081] It should be noted that the initial mixture contains incompletely dispersed tiny active ingredient agglomerates and polymeric conditioning agent microclusters; high-pressure homogenization, through high-pressure shearing and cavitation impact, crushes the agglomerates, significantly improving the uniformity of the system dispersion.

[0082] Ginsenosides and plant-based oil-controlling microparticles are evenly dispersed, allowing them to adhere evenly to the scalp during subsequent shampooing and conditioning, providing long-lasting oil control; reducing the particle size difference between different components reduces the tendency of stratification and sedimentation, and improves the storage stability of raw materials.

[0083] After homogenization, trace amounts of insoluble impurities, undissolved plant fibers, powder residues, and tiny flocculents remain. If impurities remain, the finished shampoo and conditioner raw materials will appear cloudy and have sediment, which can clog the pump and cause a grainy feeling on the scalp during use. Filtration ensures that the liquid is clear and uniform.

[0084] Rapid cooling can cause thermal expansion and contraction of the system, resulting in a sharp drop in the solubility of active ingredients and precipitation. Natural and slow cooling maintains stable solubility. Sealing and isolating air prevents ginsenosides and plant polyphenols from oxidizing and discoloring, and causing activity decay, during the cooling process of high-temperature liquid. Cooling to room temperature matches the normal storage and compounding temperature of washing and care products, eliminates temperature stress, and prevents the raw materials from separating during long-term storage.

[0085] In one embodiment of this application, in step S3, the ginsenoside compound extract is added in batches, in 2-3 even additions, with an interval of 3-5 minutes between each addition.

[0086] It should be noted that the ginsenoside compound extract is dissolved using a batch feeding process. The entire amount of ginsenoside compound extract is divided into 2-3 equal parts and evenly sprinkled into the solvent system of the reaction vessel under constant temperature and stirring in several batches. An interval of 3-5 minutes is set between two consecutive feeding operations. After the previous batch of ginsenoside compound extract has been fully dispersed and dissolved, the next batch of raw materials is added. This avoids the problem of local solute supersaturation and precipitation, and powder agglomeration caused by a large amount of material added at once, and ensures that the active ingredients of ginsenosides are completely dissolved and evenly dispersed in the solvent base.

[0087] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the present application, such design should fall within the protection scope of the present application.

Accurately weigh each component raw material according to the preset weight ratio. Store the ginsenoside compound extract and plant oil-controlling compound ingredients in a dry, airtight container away from light for later use. Remove impurities, lumps and agglomerates from the solid raw materials by sieving or manual processing to ensure that the powder is uniform and free of foreign matter. Check that the liquid raw materials are free of turbidity, sedimentation and stratification for later use. S2. Add the specified amount of solvent to the reaction vessel equipped with temperature-controlled stirring, heat it to 40-50℃ at a uniform rate, set the stirring speed to 300-400r / min, and stir at a constant temperature for 5-10min to make the temperature and concentration of the solvent system uniform and stable, thus completing the substrate pretreatment. S3. Maintain the reaction vessel at 40-50℃ and the stirring speed at 300-400r / min. Add the ginsenoside compound extract evenly to the system in 2-3 portions, with an interval of 3-5 minutes between each addition. After each addition, keep the mixture warm and stir for 15-20 minutes until completely dissolved. Then add the plant oil-controlling compound ingredients, raise the temperature to 55-60℃, adjust the stirring speed to 450-550r / min, and stir at a constant temperature for 20-25 minutes to fully disperse and blend the various active ingredients, thus obtaining the compound efficacy mother liquor. S4. After the mother liquor is prepared, stop heating and cool down to 30-35℃ at a constant speed and keep the temperature constant. Reduce the stirring speed to 200-250r / min and add the hair fluffing conditioner and moisturizing soothing agent in sequence. After all the additions are completed, stir at a low speed and constant temperature for 10-15min to make the components evenly dispersed and obtain the initial mixed raw material solution. S5. Transfer the initial mixture to a high-pressure homogenizer and homogenize it at 25-35MPa for 8-12 minutes to ensure uniform dispersion of the system components. Then, filter the mixture using a 200-300 mesh filter cloth to remove trace amounts of insoluble impurities. After filtration, seal the liquid and allow it to cool naturally to room temperature to obtain the finished washing and care raw material.
