Abstract
Description
Technical Field
[0001] This invention belongs to the field of daily chemical products technology, specifically relating to a scalp cleansing composition containing supramolecular orange-red and its preparation method. Background Technology
[0002] As consumers continue to pay increasing attention to scalp health, the gentleness and efficacy of scalp cleansing products have become core market demands. Amino acid surfactants, due to their advantages such as low irritation, weak acidity, and good skin affinity, are gradually becoming the mainstream surfactant choice for scalp cleansing products. However, existing amino acid shampoos still have the following technical shortcomings: Firstly, it is difficult to balance cleansing power and gentleness. Existing amino acid shampoos generally have weak cleansing power and loose foam, which is difficult to meet consumers' expectations for cleansing effect; if the amount of surfactant is simply increased or strong cleansing surfactants are added, it is easy to damage the scalp barrier and cause problems such as dryness, tightness and itching.
[0003] Secondly, plant extracts suffer from poor stability and rapid loss of efficacy. Rich in active ingredients such as polyphenols, flavonoids, and alkaloids, plant extracts are highly sensitive to environmental factors such as temperature, pH, and light, and are easily oxidized, hydrolyzed, or degraded during conventional high-temperature emulsification processes. The compatibility of different plant extracts within a system is also a technical challenge; improper compounding can easily lead to problems such as layering, precipitation, and discoloration.
[0004] Third, high-temperature processing damages active ingredients. Traditional shampoo production often employs high-temperature emulsification processes (usually above 55°C). These high temperatures not only destroy the molecular structure of amino acid surfactants but also lead to a significant loss of heat-sensitive active ingredients from plant extracts. Commercially available shampoo and conditioner products containing Citrus reticulata peel are not formulated specifically for the characteristics of this ingredient and do not utilize low-temperature preparation processes. During high-temperature production, a large amount of the volatile active ingredients in Citrus reticulata peel are lost, resulting in products whose efficacy is significantly different from their claims.
[0005] Fourth, conventional plant extract blends lack synergistic design. Most commercially available plant extract blends are simply additive effects, lacking formulation design based on synergistic mechanisms. The components are difficult to complement each other, and the overall efficacy is far lower than the theoretical additive value.
[0006] Fifth, amino acid shampoos can cause dryness and a slippery feeling on the skin. The amino acid surfactant system often leaves dryness, tangles, and a slippery residue after rinsing, severely impacting the user experience.
[0007] In summary, there is an urgent need to develop a scalp cleansing composition that combines gentle cleansing with high efficacy, high retention of plant active ingredients, long-term formula stability, and excellent skin feel. Summary of the Invention
[0008] The purpose of this invention is to address existing problems by providing a scalp cleansing composition containing supramolecular orange-red and its preparation method.
[0009] This invention is achieved through the following technical solution: A scalp cleansing composition containing supramolecular orange-red comprises the following components by weight percentage: (a) Mild Cleaning Surfactant System: Sodium lauroyl sarcosinate 8.0~15.0%, mainly composed of mild anionic amino acid surfactants, low irritation, scalp-friendly, and weakly acidic, matching the pH of the scalp; Coco-based glucoside 4.0~8.0%, non-ionic mild surfactant, increases and stabilizes foam, reduces irritation, and enhances cleaning synergy; Sodium lauroamphoacetate 2.0~5.0%, an amphoteric surfactant, buffers irritation, improves rinsing smoothness, and reduces false slip residue; Potassium cocoyl glycinate 3.0~6.0%, with auxiliary amino acid anions, enhances cleansing power without damaging the scalp barrier; (II) Scalp Moisturizing and Hydration System: Glycerin 1.0~3.0% provides basic moisturizing, maintains the scalp's oil-water balance, and soothes dryness and tightness; Panthenol (Vitamin B5) 0.5~2.0% repairs the scalp barrier, soothes redness, and strengthens hair roots; (III) Anti-corrosion system (compliant, mild, and non-irritating): Phenoxyethanol 0.5-1.0%, Ethylhexylglycerin 0.05-0.15%; It contains a broad-spectrum antiseptic compound, has good high-temperature stability, is compatible with cold compatibility, and does not irritate or damage the scalp; (iv) Core active ingredients: The supramolecular tangerine peel extract (2.0-5.0%) uses a supramolecular complexation encapsulation process, making it less prone to inactivation and allowing for deeper penetration. It has antibacterial and antifungal properties, reduces inflammation and redness, soothes itchy scalp and dandruff, and improves scalp sensitivity and discomfort. Sophora flavescens extract (0.3-0.8%) has antibacterial and antipruritic effects. Ginger root extract (0.2-0.6%) soothes, repairs, and improves scalp microcirculation. Witch hazel extract 0.2~0.5% has astringent, oil-controlling, anti-inflammatory, and soothing properties; Notopterygium root extract 0.2-0.5%, Acorus tatarinowii root extract 0.2-0.5%; (V) Gentle Conditioning System: Polyquaternium-10 0.2~0.4%, a cationic conditioning polymer, absorbs scalp and hair strands, anti-static, smooth and non-flat, reduces dryness and tangles; Amino emulsified silicone oil 1.0~2.5%, gentle and smooth, rinses clean without leaving a slippery residue, smooth for both dry and wet use; (vi) pH adjusters and auxiliary stabilizers: Citric acid adjusts the pH of the system to 5.5~6.0 (healthy, slightly acidic scalp). Disodium EDTA 0.1~0.2% chelates soft water and improves formula stability; Sodium chloride 0.5~1.0% is used to adjust the viscosity of the system; the balance is deionized water.
[0010] Furthermore, the preparation method of the supramolecularized citrus red stock solution is as follows: ① Raw material pretreatment: Wash, dry, and pulverize dried Citrus reticulata fruit to 20-40 mesh to obtain Citrus reticulata powder; ② Supramolecular fluid extraction: Powdered tangerine peel is put into a supramolecular fluid extraction device, using supercritical CO2 as the extractant and food-grade ethanol as the entrainer. The extraction pressure is 20-30 MPa, the extraction temperature is 35-45℃, and the extraction time is 2-4 h to obtain the extract. ③ Low-temperature concentration: The extract is concentrated at 30-40℃ and under vacuum conditions of -0.08~-0.1MPa to recover ethanol and CO2, and the concentrate is obtained. ④ Purification and refining: The concentrated solution is purified by macroporous adsorption resin, impurities are removed by washing with water, and the effective components are eluted with 70% ethanol. The eluent is concentrated at low temperature and filtered aseptically to obtain the refined solution. ⑤ Aseptic filling: The refined liquid is aseptically filled and sealed in a Class 100 clean environment to obtain the supramolecular orange red original liquid product.
[0011] Furthermore, the preparation method of Sophora flavescens extract: ① Raw material pretreatment: Select dried Sophora flavescens rhizomes that are free from mold and insect infestation, wash them with clean water under high pressure to remove surface mud and impurities, dry them with low temperature hot air until the moisture content is ≤8%, and pulverize them to 30-50 mesh to obtain uniform Sophora flavescens powder for later use. ② Supramolecular enzymatic hydrolysis and synergistic extraction: Sophora flavescens powder is put into a supramolecular low-temperature extraction device and pretreated with a compound biological enzyme (cellulase + pectinase ratio 1:0.8) for low-temperature cell wall disruption. The enzymatic hydrolysis temperature is 30-38℃ and the enzymatic hydrolysis time is 60-90 min. Then, supercritical CO2 is used as the extractant and food-grade propylene glycol is used as the green entrainer. The extraction pressure is set to 22-28 MPa, the extraction temperature is 32-40℃, and the extraction time is 2.5-3.5 h. The crude extract is obtained by low-temperature dynamic extraction. ③ Gradient low-temperature concentration: The crude extract is fed into a vacuum low-temperature concentration unit and concentrated in a gradient environment of 32-38℃ and -0.09~-0.1MPa. The entrainer and supercritical medium are recovered at low temperature throughout the process, avoiding the high-temperature decomposition and loss of matrine and oxymatrine, and obtaining a highly active concentrate. ④ Multi-stage purification and refining: The concentrated liquid is purified in stages using modified macroporous adsorption resin. First, purified water is used to wash away water-soluble impurities such as polysaccharides and ash. Then, 65% food-grade ethanol is used to selectively elute the effective components of total alkaloids of Sophora flavescens. The eluent is then purified by precision filtration through a ceramic membrane, low-temperature alcohol removal, and sterile ultrafiltration to remove macromolecular impurities and trace residues, resulting in a high-purity purified liquid. ⑤ Aseptic constant temperature filling: The refined liquid is placed in a Class 100 clean constant temperature workshop and aseptically filled and sealed in a light-proof environment at a constant temperature of 25-30℃ to obtain the finished product of supramolecular low temperature enzymatic hydrolysis Sophora flavescens extract.
[0012] Furthermore, the preparation method of ginger root extract: ① Raw material pretreatment: Select fresh dried ginger roots, remove fibrous roots and impurities, quickly wash with sterile purified water, air dry at low temperature until there is no moisture on the surface, pulverize at low temperature to 25-45 mesh, control the moisture content of the powder to ≤7%, and obtain ginger root ultrafine powder, which is then sealed at low temperature for later use. ② Supramolecular fractional fluid extraction: Ginger root powder is fed into a supercritical fractional extraction device. Supercritical CO2 is used as the main extractant and food-grade anhydrous ethanol is used as the dynamic entrainer. A segmented temperature-controlled extraction process is adopted. The first stage extraction is carried out at a pressure of 18-22 MPa and a temperature of 30-35℃ for 1 hour, and the second stage extraction is carried out at a pressure of 25-30 MPa and a temperature of 38-42℃ for 2 hours. The fractional extraction enriches heat-sensitive active ingredients such as gingerol and gingerene. The two extraction liquids are combined to obtain a mixed extract. ③ Low-temperature vacuum closed-loop concentration: The mixed extract is introduced into a closed-loop vacuum concentration system and concentrated at low temperature under the conditions of 30-36℃ and -0.085~-0.1MPa negative pressure. The closed-loop recovery of CO2 and ethanol medium prevents the volatilization and loss of active ingredients, and obtains a high-concentration ginger root concentrate. ④ Molecular Retention Purification: The concentrate is precisely purified using nanofiltration molecular retention technology to retain large molecular colloidal and fibrous impurities while retaining small molecular active ingredients. Then, it is subjected to activated carbon micro-decolorization and sterile precision filter to remove trace impurities and odors. After being allowed to stand at low temperature for 24 hours to stabilize, a highly active ginger root refined liquid is obtained. ⑤ Aseptic constant pressure filling: In a Class 100 clean and sterile environment, the refined liquid is aseptically filled under constant pressure, vacuum sealed, and cured at room temperature in the dark to obtain the finished product of supramolecular fractional extraction of ginger root extract.
[0013] Furthermore, the preparation method of witch hazel extract: ① Raw material pretreatment: Select mature North American witch hazel branches and leaves, remove dead branches and impurities, wash and remove dust with sterile water, dry at low temperature under vacuum until the moisture content is ≤6%, and pulverize at low temperature to 30-40 mesh to obtain witch hazel powder, which is then stored in a light-proof and sealed container for later use. ② Supramolecular microcapsule-assisted extraction: Witch hazel powder is put into a supramolecular extraction device, food-grade cyclodextrin is used as the microcapsule-assisted encapsulation agent, supercritical CO2 is used as the extractant and low-concentration food-grade ethanol is used as the entrainer. The extraction pressure is set to 20-26 MPa, the extraction temperature to 33-40℃ and the extraction time to 2-3 h. The active ingredients of witch hazel, such as tannins, flavonoids and polyphenols, are locked in by the supramolecular encapsulation technology to obtain the encapsulated extract. ③ Low-temperature negative pressure low-consumption concentration: The extract is sent to a low-temperature negative pressure concentration device and concentrated at low speed under vacuum conditions of 28-35℃ and -0.09~-0.1MPa. The extraction medium is gently recovered, and the polyphenols, flavonoids and other easily oxidized active ingredients are protected at low temperature throughout the process to obtain a highly active polyphenol concentrate. ④ Selective adsorption purification: The concentrate is selectively purified by a specific macroporous adsorption resin. First, water-soluble impurities and residual sugars are removed by washing with water. Then, the total polyphenols and flavonoid active components are enriched by elution with gradient ethanol. The eluent is then subjected to low-temperature desolvation, sterile ultrafiltration, and precision filtration to remove ineffective impurities and oxidation products, resulting in a high-purity witch hazel purified liquid. ⑤ Aseptic filling: In a Class 100 clean, light-proof, aseptic workshop, the refined liquid is aseptically filled, sealed and kept fresh, and then allowed to stand at low temperature to stabilize, resulting in the finished product of supramolecular polyphenol-enriched witch hazel extract.
[0014] Furthermore, the preparation method of the Notopterygium root extract is as follows: ① Raw material pretreatment: Select dried Qianghuo rhizomes that are free from mold, sulfur fumigation, and pesticide residues that meet food-grade standards.

[0016] A method for preparing the scalp cleansing composition, characterized by comprising the following steps: (1) At room temperature, add deionized water to the mixing pot in the specified amount while it is in standby mode, turn on the stirring and stir at a speed of 25 r / min, add the pre-mixed polyquaternium-10 and glycerol, and stir until dissolved. (2) While maintaining the stirring speed, add disodium EDTA, sodium lauroyl sarcosinate, cocoyl glucoside, sodium lauroyl amphoteric acid, potassium cocoyl glycinate, amino emulsified silicone oil, and panthenol in sequence, and stir until dissolved and homogeneous. (3) While maintaining the stirring speed, add the supramolecular tangerine peel stock solution, sophora flavescens extract, ginger root extract, witch hazel extract, notopterygium incisum extract, acorus tatarinowii extract, phenoxyethanol, and ethylhexylglycerin in sequence, and stir until dissolved and homogeneous. (4) Then add citric acid (adjust pH to 5.5~6.0), sodium chloride and flavoring in sequence, stir to dissolve evenly, and filter out the material.
[0017] Furthermore, the above preparation method employs a cold mixing process throughout, with the temperature controlled at 20~35℃.
[0018] The present invention has the following advantages over the prior art: (1) The first mild and cleansing surfactant cold compounding system. The present invention uses a four-fold compounding of sodium lauroyl sarcosinate, cocoyl glucoside, sodium lauroyl amphoteric acetate and potassium cocoyl glycinate. The anionic, nonionic and amphoteric surfactants work synergistically to combine mildness and cleansing power. It is low in irritation, produces fine foam, and is weakly acidic to match the physiological pH of the scalp.
[0019] (2) The core efficacy of supramolecular tangerine peel is significant. The supramolecular tangerine peel stock solution prepared by supercritical CO2 supramolecular fluid extraction technology has an active ingredient retention rate of ≥95%. The supramolecular complexation and encapsulation process makes the effective ingredients less prone to inactivation and allows for deeper penetration. Its antibacterial, anti-inflammatory, and redness-reducing effects, as well as its ability to soothe scalp itching and dandruff, are significantly better than those of ordinary tangerine peel extract.
[0020] (3) Synergistic effect of six plant extracts. The supramolecularized tangerine peel combined with extracts of six plants, namely Sophora flavescens, ginger root, witch hazel, Notopterygium incisum and Acorus tatarinowii, has been verified by experiments to have significant multiple synergistic effects: Notopterygium incisum enhances oil control and anti-inflammatory effects, Acorus tatarinowii enhances sedation, antipruritic and free radical scavenging abilities, and the combination of the six ingredients has significantly better antipruritic, oil control, antioxidant and soothing effects than single raw material, component-deficient formulas and traditional plant extract combinations.
[0021] (4) The entire cold-mixing process protects the active ingredients. The entire cold-mixing process is ≤40℃, which does not damage the structure of amino acid surfactant molecules and plant active ingredients. The formula is stable for a long time without layering or discoloration, and the retention rate of active ingredients is high.
[0022] (5) Cationic polymer + lightweight emulsified silicone oil compound conditioning system. Polyquaternium-10 is compounded with amino emulsified silicone oil to solve the pain points of amino acid shampoo such as dryness, difficulty in rinsing, and slippery feeling. It rinses clean and does not leave a slippery feeling, and is smooth when used on both dry and wet hair.
[0023] (6) The weak acid is compatible with the physiological pH of the scalp. The pH of the system is controlled at 5.5~6.0, which can protect the scalp barrier for a long time and has multiple effects such as oil control, dandruff removal and soothing.
[0024] (7) Excellent safety. After multiple skin irritation tests on rabbits, eye irritation tests on chicken embryo chorioallantoic membrane, human patch tests, and HaCaT keratinocyte MTT cytotoxicity tests, the product has been verified to be non-irritating to the skin, non-irritating to the eyes, non-sensitizing, and non-cytotoxic, and is suitable for long-term use on sensitive scalps.
