Description

Technical Field

[0001] The present invention relates to the technical field of colloidal materials, and particularly relates to a tara gum three-dimensional colloid and its preparation process, which has key application value in skin care, hair care and more scenarios requiring moisturizing and sustained release functions. Background Art

[0002] In the current field of cosmetics and personal care products, consumers' requirements for product efficacy, safety and naturalness are increasing day by day. Moisturization, as a key link in maintaining skin health and appearance, has always been one of the focuses of research in this field. The skin, as the largest organ of the human body, the normal operation of its moisturizing function is crucial for maintaining skin elasticity, softness and barrier function.

[0003] The distribution and dynamic balance of moisture in the skin are affected by various factors. Healthy skin is structurally divided into different layers. Among them, the dermis contains about 70% of water, while the superficial stratum corneum usually maintains a water content of about 13%. As the outermost layer of the skin, the stratum corneum is directly in contact with the external environment, and the stability of its water content plays a decisive role in the overall health of the skin. When the water content of the stratum corneum is lower than 13%, the keratinocytes will gradually lose their normal biomechanical properties, resulting in dry, rough skin, loss of elasticity and flexibility, and then causing a series of skin problems, such as skin tightness, desquamation, inflammation, etc.

[0004] The loss of skin moisture is mainly due to the combined action of internal and external factors. Internal factors include the slowdown of metabolism caused by aging, and the reduced generation rate of new keratinocytes, which leads to a decline in the skin's self-repair and moisturizing ability. External factors cover various environmental factors in daily life, such as pollution, cold, sunlight, etc. Pollutants will damage the skin's barrier function, making the skin more likely to lose moisture; cold weather will cause the skin blood vessels to constrict, reducing the blood supply to the skin, thus affecting the skin's moisturizing ability; long-term sunlight exposure will damage the collagen and elastic fibers in the skin, resulting in a decline in the skin's water retention ability.

[0005] At present, there are various moisturizing products on the market, and their moisturizing principles are mainly based on different chemical and physical mechanisms. Some common moisturizing ingredients include glycerin, hyaluronic acid, etc. Glycerin can increase the water content of the skin by absorbing moisture from the environment, but its moisturizing effect is relatively short-lived, and it will absorb moisture from the skin in a low-humidity environment. Hyaluronic acid has strong water absorption, can absorb a large amount of water and form a moisturizing film on the skin surface, but its stability and sustained release performance are not satisfactory in some cases.

[0006] Caesalpinia spinosa, a plant native to Peru and widely distributed in Latin America, plays an important role in the local ecosystem. It can adapt to extremely arid environments, and the endosperm of its seeds is rich in galactomannan. Galactomannan is a natural polysaccharide with a unique chemical structure and physical properties, giving it potential advantages in moisturizing. However, the development and utilization of Caesalpinia spinosa gum in the cosmetics field have not been fully explored yet. Summary of the Invention

[0007] The purpose of the present invention is to provide a three-dimensional colloid of Caesalpinia spinosa gum, which has high-efficiency moisturizing performance, slow-release function of active ingredients, and good film-forming property. It can be widely used in skin and hair care products, and has application prospects in the pharmaceutical field, food industry, and textile industry.

Its preparation process integrates multiple technologies and precisely controls parameters to ensure product quality, enriches the types of colloid materials, conforms to the trend of sustainable development, and has a positive and profound impact on the development of multiple industries.

[0009] The unique three-dimensional structure of the three-dimensional colloid of Caesalpinia spinosa gum is constructed by galactomannan extracted from the endosperm of Caesalpinia spinosa seeds. As a material from a natural source, it enriches the types of colloid materials and conforms to the concept of sustainable development. This colloid performs excellently in terms of product performance. It has excellent moisturizing performance and can effectively maintain the skin's hydration state. Its slow-release function of active ingredients can extend the time of efficacy and improve the utilization rate of active ingredients. The good film-forming property provides a protective barrier for the skin and hair. These advantages make it have broad application potential in cosmetics and personal care products, promoting product innovation and technological upgrading, and prompting the industry to develop towards the direction of natural and high efficiency. At the same time, its performance characteristics can be used for drug slow-release and wound dressings in the pharmaceutical field, as an additive to improve texture and taste in the food industry, and endow fabrics with functionality in the textile industry.

[0010] The preparation process of the three-dimensional colloid of Caesalpinia spinosa gum provided by the present invention integrates advanced technologies such as ultrasonic-assisted extraction and microemulsification, realizing efficient extraction of raw materials and precise preparation of products. Precisely controlling the parameters of each step ensures the consistency and stability of product quality, meeting the requirements of industrial production.

[0011] A Caesalpinia spinosa gum three-dimensional colloid, whose basic composition includes a Caesalpinia spinosa three-dimensional colloid structure and multiple active ingredients; the Caesalpinia spinosa three-dimensional colloid structure is mainly composed of galactomannan extracted from the endosperm of Caesalpinia spinosa seeds, and its molecular structure is that linear mannose chains are connected by glycosidic bonds and carry randomly distributed side chains composed of galactose residues, and the ratio of mannose to galactose is 3:1; the multiple active ingredients include one or a combination of ingredients such as vitamin C, hyaluronic acid, ceramide, squalane, bakuchiol, collagen, soluble collagen, acetyl hexapeptide-8, glutathione, sodium DNA, lactic acid, mandelic acid, succinic acid, ferulic acid, tranexamic acid, kojic acid, resveratrol, diosmin, sodium ascorbyl phosphate, ascorbyl glucoside, 3-O-ethyl ascorbic acid, tocopheryl acetate, retinol, retinol palmitate, hydroxypinacolone retinoate, α-arbutin, niacinamide, ubiquinone, glabridin, panthenol, ectoin, ergothioneine, hydroxyprogesterone caproate, and plant extracts.

[0012] The galactomannan extracted from the endosperm of Caesalpinia spinosa seeds has a specific molecular structure, where linear mannose chains are connected by glycosidic bonds and carry randomly distributed side chains composed of galactose residues, and the ratio of mannose to galactose is 3:1. This unique structure endows the Caesalpinia spinosa three-dimensional colloid structure with excellent properties. For example, its molecular structure gives it good water solubility, enabling it to form a stable colloid system in water, laying the foundation for subsequent combination with multiple active ingredients and use in various application scenarios. In cosmetics, it can be evenly dispersed in the formulation to ensure uniform and stable product texture; this structure also has good affinity with the skin or hair surface. When applied to skin care, it can form a uniform protective film on the skin surface, interact with the structure and components of the skin cutin layer, and enhance the skin's barrier function. For hair care, it can adhere to the hair surface, fill the gaps between the hair scales, make the hair smoother and shinier, and at the same time play a role in moisturizing and protecting the hair from external damage.

[0013] The multi-active ingredients include a combination of various components such as vitamin C, hyaluronic acid, ceramides, squalane, bakuchiol, collagen, soluble collagen, acetyl hexapeptide-8, glutathione, sodium DNA, lactic acid, mandelic acid, succinic acid, ferulic acid, tranexamic acid, kojic acid, resveratrol, diosmin, sodium ascorbyl phosphate, ascorbyl glucoside, 3-O-ethyl ascorbic acid, tocopheryl acetate, retinol, retinol palmitate, hydroxypinacolone retinoate, alpha-arbutin, niacinamide, ubiquinone, glabridin, panthenol, ectoin, ergothioneine, hydroxyprogesterone caproate, plant extracts, etc. The plant extracts include one or more of Lithothamnion calcareum extract, Enteromorpha compressa extract, Cichorium intybus root extract, Sapindus mukorossi fruit extract, Ceratonia siliqua seed extract.

Through the combination of different active ingredients, products with multiple functions can be developed according to different needs to meet the personalized needs of different consumers, such as moisturizing and repair products for dry skin, anti-aging and antioxidant products for mature skin, soothing care products for sensitive skin, etc. ;

[0014] There is a synergistic effect between the three-dimensional colloidal structure of Caesalpinia spinosa gum and its multiple active ingredients. The colloidal structure can serve as a carrier to effectively encapsulate and disperse the multiple active ingredients, protecting the active ingredients from the influence of external environmental factors such as oxidation and light. At the same time, it controls the release rate of the active ingredients to achieve a sustained-release effect. In skin care products, when applied to the skin, the colloidal structure gradually releases the active ingredients therein. Antioxidant ingredients such as vitamin C can neutralize the free radicals constantly generated on the skin surface in a timely manner. Hyaluronic acid continuously replenishes moisture to the skin, and repair ingredients such as ceramide play a role in repairing the skin barrier for a long time, enabling various active ingredients to continuously exert their effects on the skin surface, cooperate with each other, and jointly improve the skin condition, providing a more comprehensive and lasting care effect. In hair care, the colloidal structure can help the active ingredients better adhere to the hair. Moisturizing ingredients such as squalane penetrate deep into the hair to nourish it, and plant extracts play antibacterial and antioxidant roles to protect the hair from environmental damage, enabling the hair to be comprehensively cared for while being cleaned and moisturized, enhancing the health and beauty of the hair.

[0015] This basic composition enables the three-dimensional colloid of Caesalpinia spinosa gum to have broad application adaptability in multiple fields. In the cosmetics field, it can be used to prepare various skin care products (such as creams, lotions, serums, etc.), color cosmetics (such as foundations, lipsticks, etc.), and hair care products (such as shampoos, conditioners, hair masks, etc.). In the pharmaceutical field, its good biocompatibility and sustained-release performance make it promising for application in drug delivery systems. For example, drugs can be encapsulated in the colloid to achieve targeted delivery and slow release of drugs, improving drug efficacy and reducing drug side effects. It can also be used for wound dressings. The protective film formed by the colloidal structure helps maintain a moist environment for the wound, promoting wound healing. At the same time, the antibacterial and anti-inflammatory effects of active ingredients such as plant extracts can prevent wound infection. In the food industry, it can be used as a natural food additive, such as a humectant, thickener, or stabilizer, to improve the texture and taste of food. And due to its natural origin, it meets consumers' pursuit of healthy food. In other fields, such as in agriculture, it can be used for seed coating to protect seeds and provide nutrients. In the textile industry, it can be used for fabric finishing to endow fabrics with properties such as softness, moisture retention, and antibacterial properties, developing functional textiles, etc., showing broad application prospects and huge market potential.

[0016] The present invention provides an optimized preparation process for the three-dimensional colloid of Caesalpinia spinosa gum. By precisely controlling the parameters of each step, the extraction of high-purity galactomannan, the construction of a stable three-dimensional colloidal structure, and the effective integration of active ingredients are achieved, thereby obtaining a three-dimensional colloid product of Caesalpinia spinosa gum with excellent moisture retention, sustained-release, and protection properties.

[0017] The preparation process for the three-dimensional colloid of Caesalpinia spinosa gum provided by the present invention specifically includes the following steps: S1 Raw material pretreatment: Take mature Caesalpinia spinosa seeds, remove impurities, separate the endosperm, wash, dry, and crush it to a particle size of 50 - 200 μm to obtain pretreated Caesalpinia spinosa seed endosperm powder. Through operations such as removing impurities, separating the endosperm, washing, drying, and crushing, it provides pure and appropriately sized Caesalpinia spinosa seed endosperm powder for the subsequent extraction of galactomannan, ensuring the raw material quality and facilitating the extraction process.

[0018] S2 Galactomannan extraction: The pretreated Caesalpinia spinosa seed endosperm powder uses water or ethanol as a solvent, mixes at a specific ratio, heats up and stirs for extraction, filters residue in multiple stages, and concentrates under reduced pressure to obtain a high-purity galactomannan solution. Using water or ethanol as a solvent, through mixing, heating up and stirring for extraction, filtering residue in multiple stages, and concentrating under reduced pressure, a high-purity galactomannan solution is obtained from the endosperm powder, which is a key raw material for constructing the colloidal structure.

[0019] S3 Preparation of three-dimensional colloidal pre-gel: The high-purity galactomannan solution is put into a reaction kettle, dissolved in an appropriate amount of solvent, heated under pressure and stirred for 1 - 3 hours until the galactomannan is completely dissolved to form a uniform pre-gel solution, and circulated in a constant-temperature pipeline at 40 - 50 °C for 30 - 60 minutes to obtain a three-dimensional colloidal pre-gel. Dissolving the high-purity galactomannan solution in the reaction kettle and circulating it through the constant-temperature pipeline to form a uniform and stable pre-gel, which lays a structural foundation for the addition of active ingredients and the final shaping of the colloid.

[0020] S4 Integration and addition of active ingredients: Using a multi-capillary injection system, inject the pre-selected and ultrasonically dispersed or microemulsified integrated active ingredients into the pre-gel, and control the injection pressure at 0.3 - 0.8 MPa. After integrating the active ingredients by ultrasonic dispersion or microemulsification, use the multi-capillary injection system to uniformly inject them into the pre-gel to achieve uniform distribution and effective integration of the active ingredients in the colloid, endowing the product with multiple functions.

[0021] S5 Shaping and post-treatment: The pre-gel injected with active ingredients is shaped through an ultra-rapid condensation system, and the condensation rate is controlled at 50 - 150 °C / minute to make the solute reach the critical concentration, forming a three-dimensional colloid and active ingredient complex. After gradient drying and curing treatment, a Caesalpinia spinosa gum three-dimensional colloid product is obtained.

[0022] In the raw material pretreatment step of the preparation process of the Caesalpinia spinosa gum three-dimensional colloid of the present invention, by removing impurities and separating the endosperm, it prevents harmful substances from mixing in, improves the extraction purity of galactomannan, provides high-quality raw materials for subsequent processing, and at the same time avoids interference from impurities in chemical reactions. The operations of washing, drying, and crushing improve the hygienic safety of the raw materials, optimize the water content and particle size, facilitate subsequent solvent extraction, increase the contact area, and thus effectively improve the extraction efficiency of galactomannan, playing a crucial fundamental role in ensuring the quality of the final product.

[0023] Impurities in mature Caesalpinia spinosa seeds (such as soil, stones, shriveled seeds, etc.) can affect the subsequent processing process and product quality. Removing impurities can ensure the purity of raw materials and avoid the introduction of harmful substances or interference with chemical reactions by impurities in subsequent steps; separating the endosperm is the key to obtaining galactomannan. The endosperm is the main storage site of galactomannan, and precise separation can improve the extraction efficiency of target components. Washing the endosperm can remove residual impurities, microorganisms and other harmful substances on the surface, ensuring the hygienic safety of raw materials; the drying process reduces the water content of the endosperm, prevents the growth of microorganisms, and facilitates subsequent grinding operations; grinding to a particle size of 50 - 200 μm can increase the contact area between the endosperm powder and the solvent, improve the extraction rate of galactomannan, and make the extraction process more sufficient and efficient.

[0024] Preferably, the raw material pretreatment in step S1 specifically includes the following operations: Select mature Caesalpinia spinosa seeds without pests and diseases, and remove the impurities therein by methods such as winnowing, screening or manual selection; use mechanical separation or chemical separation methods (such as enzymatic hydrolysis-assisted separation) to separate the endosperm from the seeds to obtain pure endosperm tissue; after washing the separated endosperm with clean water or ultrasonic-assisted water washing 2 - 4 times, dry it in a low-temperature and low-humidity environment at 30 - 50 °C and a relative humidity of 30 - 50% for 12 - 24 hours until the water content of the endosperm is 7 - 10%; use a grinder or crusher to grind the dried endosperm, control the grinding particle size between 50 - 200 μm, and obtain the pretreated Caesalpinia spinosa seed endosperm powder for standby.

[0025] Removing impurities and separating the endosperm mainly remove impurities by methods such as winnowing, screening or manual selection. Winnowing can separate impurities based on the weight difference between impurities and seeds, screening can select pure seeds according to particle size, and manual selection can further ensure the complete removal of impurities; when separating the endosperm by mechanical separation or chemical separation (such as enzymatic hydrolysis-assisted separation), it is necessary to select a suitable method according to the seed characteristics to ensure the complete separation of the endosperm without damage, laying a foundation for the subsequent extraction of high-quality galactomannan. When washing, it can be washed with clean water multiple times or ultrasonic-assisted water washing (2 - 4 times). Ultrasonic assistance can enhance the cleaning effect by using the cavitation effect of ultrasonic waves to more thoroughly remove impurities; the drying temperature is controlled at 30 - 50 °C and a relative humidity of 30 - 50% in a low-temperature and low-humidity environment for 12 - 24 hours. Such conditions can avoid the damage of high temperature to the endosperm components, and the slow drying process helps to maintain the structural integrity of the endosperm, making the water content reach the ideal range of 7 - 10%; the grinding particle size is between 50 - 200 μm. If it is too small, it will cause powder agglomeration, and if it is too large, it will reduce the contact area and affect the extraction effect. The appropriate particle size can ensure the smooth progress of the extraction process.

[0026] In the galactomannan extraction step of the preparation process of the tara gum three-dimensional colloid of the present invention, a suitable solvent and ratio are selected and mixed. According to its chemical properties, the extraction rate is increased, and the heating, stirring and leaching parameters are precisely controlled to accelerate dissolution and ensure structural stability. Multi-stage filtration is used to remove residues and impurities to obtain a pure extract, avoiding affecting the colloid properties. Vacuum concentration is carried out at low temperature, which can not only increase the concentration but also protect its structure, providing sufficient and high-purity galactomannan for the preparation of high-quality colloids, and is an important link to achieve good product performance and stability.

[0027] Water or ethanol is used as a solvent to dissolve galactomannan. The selection basis includes factors such as raw material characteristics, product requirements and cost. Water is a green and environmentally friendly solvent with low cost and has good compatibility with galactomannan, which can effectively extract the target components. Ethanol can be used for specific requirements in some cases, such as adjusting polarity, improving extraction selectivity or subsequent process requirements. A specific ratio mixture (material-liquid ratio 1:5 - 1:15 g / mL) ensures that there is enough solvent to dissolve galactomannan, while avoiding solvent waste, making the raw material and solvent fully contact to form a uniform suspension or mixture, creating good conditions for subsequent leaching. Heating can accelerate the thermal movement of galactomannan molecules, making it easier to dissolve from the endosperm powder into the solvent and increasing the extraction rate. Stirring keeps the solution uniform, ensuring full contact between the endosperm powder and the solvent, avoiding local high or low concentration, and promoting the dissolution equilibrium of galactomannan to move towards the dissolution direction. During the leaching process, ultrasonic-assisted extraction or complex enzyme-assisted extraction can be selected according to the actual situation to further improve the extraction efficiency and quality. After the leaching is completed, the solution contains a large amount of impurities, such as undissolved endosperm tissue fragments, fibers, etc. Multi-stage filtration to remove residues can effectively remove these impurities, obtain a clear galactomannan extract, improve product purity, and avoid the influence of impurities on subsequent processes and product quality. The volume of the extract after multi-stage filtration is large. Vacuum concentration can quickly remove the solvent at a lower temperature, increase the concentration of galactomannan, obtain a high-purity galactomannan solution, facilitate subsequent process operations, reduce solvent usage, lower costs, and improve production efficiency.

[0028] Preferably, the extraction of galactomannan in step S2 specifically includes the following steps: S21 Solvent selection and mixing: Take a certain amount of crushed seed endosperm powder, mix it with water or an ethanol solution with a volume fraction of 50 - 95% according to the material-liquid ratio of 1:5 - 1:15 g / mL, and use a mechanical stirrer to stir at a lower speed of 100 - 200 rpm for 5 - 10 minutes during the mixing process to ensure full contact between the powder and the solvent and form a uniform suspension or mixture; S22 Heating and Stirring Extraction: Heat the mixed solution with a heating rate controlled at 1 - 3 °C per minute. When the temperature rises to the target temperature between 50 - 80 °C, maintain this temperature for stirring extraction; the stirring method can be mechanical stirring or magnetic stirring, with the stirring speed set at 200 - 500 rpm and the extraction time being 2 - 6 hours; during the extraction process, ultrasonic-assisted extraction or composite enzyme-assisted extraction can be selected according to the actual situation. S23 Multi-stage Filtration to Remove Residue: After the extraction is completed, first perform a coarse filtration operation, using multiple layers of gauze or a filter screen with a pore size of 50 - 100 μm for filtration to remove larger particulate residues and obtain a coarse filtrate; then perform a fine filtration operation, select centrifugal filtration, transfer the coarse filtrate to a centrifuge and centrifuge at a speed of 3000 - 8000 rpm for 10 - 30 minutes, and take the supernatant after centrifugation to obtain a clear galactomannan extract. S24 Vacuum Concentration: Transfer the fine-filtered galactomannan extract to a rotary evaporator in a vacuum concentration device, concentrate it under the condition of a pressure of 0.05 - 0.1 MPa, with the temperature controlled at 40 - 60 °C. When the solution volume is reduced to 1 / 3 - 1 / 5 of the original, stop the concentration to obtain a high-purity galactomannan solution with a galactomannan content of 60 - 90%.

[0029] When water is selected as the solvent, it is suitable for most cases, which can ensure that the extracted galactomannan has good natural properties and is low in cost. If ethanol is selected, different volume fractions (50-95%) can be adjusted according to the solubility of galactomannan and the subsequent processing requirements. Higher volume fraction ethanol has advantages in extracting certain galactomannan with fewer impurities, but the cost is higher and more stringent alcohol removal treatment is required later. The solid-liquid ratio affects the extraction efficiency and cost. A lower solid-liquid ratio will lead to incomplete extraction, while an excessively high solid-liquid ratio will increase the solvent usage and subsequent processing costs. During the mixing process, the mechanical agitator stirs at a lower speed of 100-200rpm for 5-10 minutes, which can ensure that the powder and the solvent are fully mixed without generating too much heat or damaging the raw material structure due to too fast stirring. The heating rate is controlled at 1-3℃ / minute. Too fast heating will cause local overheating, which will degrade or denature galactomannan and affect product quality. Too slow heating will prolong the extraction time and reduce production efficiency. The target temperature is between 50-80℃. This temperature range is determined based on the solubility characteristics of galactomannan. At this temperature, galactomannan has good solubility and can maintain structural stability. The stirring speed is set at 200-500rpm. The appropriate stirring speed can ensure uniform mixing of the solution. Too low stirring speed cannot achieve full contact, and too high stirring speed will destroy the molecular structure of galactomannan. The extraction time is 2-6 hours. If the time is too short, the extraction will be incomplete, and if it is too long, it will increase the dissolution of impurities or waste energy. The specific time needs to be determined based on factors such as the nature of the raw materials, solvent selection and target extraction rate. In multi-stage filtration and residue removal, coarse filtration uses multi-layer gauze or a filter with a pore size of 50-100μm to remove larger particle impurities and preliminarily purify the solution; centrifugal filtration is selected for fine filtration, with a centrifugal speed of 3000-8000rpm and a time of 10-30 minutes. Appropriate centrifugal parameters are selected according to the size of impurity particles and the properties of the solution to ensure that fine impurities are effectively removed and high-quality clarified extracts are obtained; different filtration methods and parameter combinations are suitable for production of different scales and requirements, ensuring the filtration effect while improving production efficiency. The concentration is carried out under the conditions of pressure of 0.05-0.1MPa and temperature of 40-60°C. The reduced pressure can reduce the boiling point of the solvent, so that the solvent can evaporate at a lower temperature, thereby avoiding the damage of galactomannan to the original volume and ensuring the product quality. The concentration is stopped when the volume of the solution is reduced to 1 / 3-1 / 5 of the original volume. At this time, the concentration of the obtained galactomannan solution is 60-90%. This concentration range is suitable for the subsequent pre-gel preparation steps, which can not only ensure the stability of galactomannan in the solution, but also enable the pre-gel to form a good structure. At the same time, too high a concentration will cause the solution to be too viscous, affecting the operation and product uniformity.

[0030] During ultrasonic-assisted extraction, the ultrasonic frequency is 20 - 50 kHz, the power is 100 - 500 W, and intermittent ultrasonic treatment is used. The ultrasonic cavitation effect is utilized to break the plant cell wall, making galactomannan more easily dissolved, while avoiding overheating of the solution and affecting the extraction effect. During complex enzyme-assisted extraction, 0.5 - 2% of the complex enzyme based on the mass of the endosperm powder is added at 50 - 60 °C. The enzyme functions at this temperature to enzymatically hydrolyze the cell wall components and release galactomannan. Subsequently, the temperature is raised to 70 - 80 °C and continuous stirring extraction is carried out to further increase the dissolution rate of galactomannan. A buffer solution is added during the enzymatic hydrolysis process to control the pH value between 4.5 - 6.5 to ensure that the enzyme activity is in the optimal state and improve the extraction efficiency and quality.

[0031] Further, the auxiliary extraction of the step S22 for heating and stirring extraction specifically includes the following operations: During ultrasonic-assisted extraction, the ultrasonic frequency is selected to be 20 - 50 kHz, the ultrasonic power is between 100 - 500 W, and the ultrasonic treatment time is intermittent. For every 15 - 30 minutes of ultrasonic treatment, it is paused for 5 - 10 minutes, and the total ultrasonic treatment time accounts for 1 / 3 - 1 / 2 of the extraction time; During complex enzyme-assisted extraction, after the temperature is raised to 50 - 60 °C, 0.5 - 2% of the complex enzyme based on the mass of the endosperm powder, including cellulase, hemicellulase, pectinase, etc., is added to the mixture, and it is stirred at 200 - 300 rpm for 1 - 2 hours at this temperature. Then the temperature is raised to 70 - 80 °C and continuous stirring extraction is carried out for 1 - 2 hours. An appropriate amount of buffer solution is added during the enzymatic hydrolysis process to control the pH value of the solution to remain between 4.5 - 6.5.

[0032] The ultrasonic frequency is selected within the range of 20 - 50 kHz. This frequency can generate ultrasonic waves with appropriate intensity, causing strong cavitation in the solvent. When the cavitation bubbles burst instantaneously, a local high-temperature and high-pressure environment, as well as strong shock waves and microjets, are produced. These physical effects can destroy the cell wall structure of the endosperm of Caesalpinia spinosa seeds, making it easier for galactomannan to be released from the cells into the solvent, thus significantly improving the extraction efficiency. Compared with traditional simple stirring extraction, ultrasonic-assisted extraction can obtain a higher extraction rate in a shorter time, shorten the production cycle, and improve production efficiency. The ultrasonic power is between 100 - 500 W. The appropriate power can provide sufficient energy to maintain the intensity of cavitation, but will not cause the solution to overheat or the galactomannan structure to be damaged due to excessive power. Within this power range, ultrasonic waves can effectively act on the endosperm powder, accelerating the dissolution process of galactomannan and making the extraction more complete. Intermittent ultrasonic treatment is adopted, with a pause of 5 - 10 minutes every 15 - 30 minutes of ultrasonic treatment, and the total ultrasonic treatment time accounts for 1 / 3 - 1 / 2 of the extraction time. This method can prevent the solution from overheating due to long-term continuous ultrasonic treatment. Overheating will lead to the degradation or denaturation of galactomannan or other active ingredients, affecting the product quality. Intermittent ultrasonic treatment can not only utilize the cavitation effect of ultrasound to promote extraction, but also allow the solution to dissipate heat during the pause time, keeping the temperature within an appropriate range, thereby protecting the structure and activity of galactomannan and other existing active ingredients, ensuring that the extracted galactomannan has good performance and quality, and providing high-quality raw materials for the subsequent preparation of high-performance Caesalpinia spinosa gum three-dimensional colloids.

[0033] For the complex enzyme-assisted extraction, the complex enzyme (such as cellulase, hemicellulase, pectinase, etc.) is added after the temperature is raised to 50-60 °C. This temperature range is the suitable temperature interval for these enzymes to exhibit their best activities. The complex enzyme can specifically act on the components of the endosperm cell wall of Caesalpinia spinosa seeds. For example, cellulase decomposes cellulose, hemicellulase acts on hemicellulose, and pectinase decomposes pectin, thereby destroying the cell wall structure and making it easier for galactomannan to be released from the cells into the solvent. Under the action of the enzyme, the barrier effect of the cell wall is weakened, and the solvent can more effectively contact galactomannan, greatly increasing the dissolution rate of galactomannan and making the extraction more complete. Stir at 200-300 rpm for 1-2 hours at 50-60 °C. The stirring speed can ensure that the enzyme is fully mixed with the endosperm powder, enabling the enzyme to act uniformly on the cell wall, and will not generate excessive heat or mechanical shear force to damage the structure and activity of the enzyme due to too fast stirring. The enzymatic hydrolysis process at this stage is a critical period for cell wall decomposition. An appropriate combination of temperature, stirring speed, and time can ensure that the complex enzyme fully functions, maximally decomposes the cell wall, and releases galactomannan. Subsequently, the temperature is raised to 70-80 °C and stirring extraction is continued for 1-2 hours. Further increasing the temperature helps the dissolution of galactomannan in the solvent and can also inactivate the enzyme after it has completed the cell wall decomposition function, avoiding adverse effects of the enzyme on galactomannan in the extract and subsequent processes. An appropriate buffer solution is added during the entire enzymatic hydrolysis process to control the pH value between 4.5 and 6.5. This is because the activity of the complex enzyme is very sensitive to the pH value. Maintaining within this pH range can ensure that the enzyme is always in the best active state, improve the enzymatic hydrolysis efficiency, and guarantee the extraction effect of galactomannan. By optimizing these extraction conditions, a galactomannan solution with higher purity and better quality can be obtained, laying a solid foundation for the preparation of high-quality Caesalpinia spinosa gum three-dimensional colloid, and also helping to improve the stability and performance consistency of the product.

[0034] In the three-dimensional colloid pre-gel preparation step of the Caesalpinia spinosa gum three-dimensional colloid preparation process of the present invention, the temperature is raised and the pressure is increased with stirring for dissolution in a high-pressure reactor to promote the full dissolution of galactomannan to form a uniform and transparent solution, laying a foundation for the formation of the colloid structure; the constant-temperature pipeline circulation treatment further optimizes the structure, eliminates non-uniformity, and improves the uniformity and stability of the pre-gel; at the same time, the reaction parameters are precisely controlled to adjust the properties of the pre-gel, thereby affecting the subsequent colloid properties, and ultimately helping to obtain a Caesalpinia spinosa gum three-dimensional colloid product with excellent performance and stable structure.

[0035] Transfer the high-purity galactomannan solution to a high-pressure reactor, and carry out the operations of heating, pressurizing and stirring for dissolution in a closed environment. Precisely control the reaction conditions to ensure that the galactomannan is fully dissolved to form a uniform pre-gel solution; the sealing performance of the reactor ensures that the reaction process is not interfered by external impurities, and at the same time facilitates the adjustment of parameters such as temperature and pressure, providing a stable environment for the preparation of high-quality pre-gels. Heating enables the galactomannan molecules to obtain sufficient energy to overcome the intermolecular forces and accelerate the dissolution process; pressurization can increase the boiling point of the solvent, allowing the reaction to proceed at a higher temperature, and at the same time increasing the contact opportunities between galactomannan molecules and solvent molecules to promote dissolution; stirring ensures the uniformity of the solution, prevents local overheating or uneven concentration, and enables the galactomannan to be fully dissolved in the solvent to form a uniform and transparent pre-gel solution, laying a foundation for the subsequent formation of the colloidal structure. The pre-gel solution circulates in a constant-temperature pipeline at 40-50 °C, which can enable the galactomannan molecules to further interact and arrange at a constant temperature, optimize the pre-gel structure, and make it more uniform and stable; the constant-temperature circulation process helps to eliminate the local non-uniformity generated during the heating, pressurizing and stirring dissolution process, promotes the formation and improvement of the colloidal structure, improves the quality of the pre-gel, and lays a foundation for finally obtaining a three-dimensional colloid with excellent performance.

[0036] Preferably, the preparation of the three-dimensional colloid pre-gel in step S3 specifically includes the following operations: Transfer the high-purity galactomannan solution to a high-pressure reactor, add an appropriate amount of water or buffer solution as a solvent so that the final concentration of galactomannan is 5-20%, and seal the reactor; Under the condition that the stirring speed is 300-600 rpm, raise the temperature in the reactor to 70-90 °C at a heating rate of 2-5 °C per minute, and at the same time apply a pressure of 0.1-0.5 MPa, and maintain stirring at this temperature and pressure for 1-3 hours until the galactomannan is completely dissolved to form a uniform and transparent pre-gel solution; After the dissolution is completed, transfer the pre-gel solution to a constant-temperature circulation system through a pipeline. The temperature in the pipeline is maintained at 40-50 °C, and the solution circulates in the pipeline for 30-60 minutes to promote the further stability and structure optimization of the pre-gel, and obtain a three-dimensional colloid pre-gel.

[0037] It is crucial to select a high-pressure reactor with suitable materials and good sealing performance. The materials should be compatible with the galactomannan solution and subsequent operating conditions to prevent reactor corrosion or solution contamination. Heat the temperature inside the reactor to 70 - 90°C at a heating rate of 2 - 5°C per minute. An overly fast heating rate will cause local overheating, leading to the degradation of galactomannan or the formation of an uneven structure; an overly slow rate will prolong the production cycle. The target temperature range of 70 - 90°C is determined based on the dissolution characteristics of galactomannan and the requirements for gel formation. Within this temperature range, galactomannan can dissolve sufficiently and is conducive to the formation of a stable pre-gel structure. Apply a pressure of 0.1 - 0.5 MPa. An appropriate pressure can increase the boiling point of the solvent and promote the dissolution process, but too high a pressure requires excessive equipment requirements and increases safety risks. The stirring speed is 300 - 600 rpm, which can ensure uniform mixing of the solution. An overly low stirring speed will result in uneven dissolution, and an overly high speed will introduce too many bubbles, affecting the quality of the pre-gel. Stir continuously for 1 - 3 hours. Too short a time will cause incomplete dissolution of galactomannan, affecting the pre-gel structure and performance; too long will increase energy consumption and production costs, and it needs to be optimized according to the actual situation. The temperature inside the pipeline is maintained at 40 - 50°C. This temperature range is conducive to the slow adjustment of galactomannan molecules and the formation of a stable structure. Too high or too low a temperature will affect the optimization effect of the pre-gel structure. The circulation time is 30 - 60 minutes. Too short a time will not fully achieve structure optimization, and too long will have an adverse effect on the pre-gel structure or increase the production cycle. The circulation flow rate is 5 - 20 L / min, which is adjusted according to the size of the reactor and the actual situation of the pipeline system to ensure uniform and stable circulation of the solution in the pipeline and achieve good structure optimization effects.

[0038] In the step of integrating and adding active ingredients in the preparation process of the tara gum three-dimensional colloid of the present invention, ultrasonic dispersion or microemulsification is used to integrate the active ingredients to break the agglomeration and form a stable system, ensuring their uniform distribution, avoiding problems during subsequent addition, and ensuring the uniform exertion of the product efficacy. The multi-capillary injection system injects the active ingredients under appropriate conditions to achieve precise and uniform addition, enabling the rapid mixing of the active ingredients with the pre-gel. This not only enables the slow release of the active ingredients, prolongs the action time, and improves the utilization rate, but also promotes the synergistic effect between the active ingredients and with the colloid structure, enhancing the comprehensive performance of the product and meeting diverse requirements.

[0039] Select a variety of active ingredients according to the product's functional requirements (such as vitamin C, hyaluronic acid, plant extracts, ceramides, etc.). After mixing them with a dispersant or emulsifier, they are integrated by ultrasonic dispersion or microemulsification methods, so that the active ingredients are evenly dispersed in the system, forming a stable dispersion or emulsion. This helps to improve the stability of the active ingredients, prevent their aggregation or precipitation, and at the same time facilitates subsequent accurate addition to the pre-gel, ensuring the uniform distribution of the active ingredients in the final product, thereby fully exerting their efficacy. The integrated active ingredient dispersion or emulsion is injected into the pre-gel by a multi-capillary injection system to achieve accurate and uniform addition of the active ingredients in the pre-gel; during the injection process, the pre-gel is kept slightly stirred, which helps the active ingredients to be quickly and evenly mixed with the pre-gel, avoiding too high or too low local concentration, ensuring the uniform distribution of the active ingredients in the final three-dimensional colloidal product, making the performance of each part of the product consistent, and effectively exerting the efficacy of the active ingredients.

[0040] Preferably, the integration and addition of the active ingredients in step S4 specifically include the following steps: S41 Active ingredient integration: According to the functional requirements of the product, select one or more active ingredients, including vitamin C, hyaluronic acid, bakuchiol, collagen, soluble collagen, acetyl hexapeptide-8, glutathione, sodium DNA, lactic acid, mandelic acid, succinic acid, ferulic acid, tranexamic acid, kojic acid, resveratrol, diosmin, sodium ascorbyl phosphate, ascorbyl glucoside, 3-O-ethyl ascorbic acid, tocopheryl acetate, retinol, retinol palmitate, hydroxypinacolone retinoate, α-arbutin, niacinamide, ubiquinone, glabridin, panthenol, ectoin, ergothioneine, hydroxyprogesterone caproate, plant extracts (such as chamomile extract, green tea extract, Lithothamnion calcareum extract, Enteromorpha compressa extract, chicory root extract, sapindus fruit extract, carob seed extract, etc.), ceramides, etc.; mix the active ingredients with an appropriate amount of dispersant or emulsifier, and integrate them by ultrasonic dispersion with an ultrasonic frequency of 20-50 kHz for 10-30 minutes or microemulsification with a pressure of 50-150 MPa and a circulation times of 2-5 times to prepare a uniform and stable active ingredient dispersion or emulsion; S42 Active ingredient addition: Use a multi-capillary injection system to inject the active ingredient dispersion or emulsion into the three-dimensional colloidal pre-gel at an injection pressure of 0.3-0.8 MPa. During the injection process, keep the pre-gel in a slightly stirred state, with a stirring speed of 100-300 rpm, and the addition amount of the active ingredient accounts for 5-50% of the mass of the final colloidal product.

[0041] During ultrasonic dispersion, the ultrasonic frequency is 20 - 50 kHz and the time is 10 - 30 minutes. Appropriate ultrasonic frequency and time can effectively break up the aggregates of active ingredients and disperse them evenly. However, ultrasonic treatment for too long will cause partial inactivation of the active ingredients. The microemulsification method involves cycling 2 - 5 times under a pressure of 50 - 150 MPa. High pressure can make the active ingredients and emulsifiers form smaller and more stable emulsion droplets. However, too high a pressure requires high equipment requirements. The number of cycles needs to be determined according to the properties of the active ingredients and the required emulsion stability to ensure that the active ingredients are fully emulsified and the emulsion is stable. At the same time, it is also crucial to select appropriate dispersants or emulsifiers. Their types and dosages will affect the dispersion effect and stability of the active ingredients and need to be screened and optimized according to the characteristics of the active ingredients.

[0042] The multi-capillary injection system is a key device in the preparation process of the tara gum three-dimensional colloid in the present invention for precisely and evenly injecting the integrated active ingredient dispersion or emulsion into the three-dimensional colloid pre-gel. This system can precisely control the injection pressure, which is controlled between 0.3 - 0.8 MPa in the present invention. This pressure range is carefully designed to ensure that the active ingredients can be smoothly injected into the pre-gel without damaging the structure of the pre-gel due to excessive pressure, thus ensuring the accuracy and stability of the active ingredient addition process. If the injection pressure is too low, the active ingredients cannot be fully injected into the pre-gel, resulting in uneven distribution of the active ingredients and affecting the overall performance of the product. While too high a pressure will damage the structure of the pre-gel, changing its original physical and chemical properties and thus affecting the quality of the final product. During the injection process, the pre-gel is kept in a slightly stirred state with a stirring speed of 100 - 300 rpm. This slight stirring helps the injected active ingredients to quickly mix evenly with the pre-gel, avoiding the situation of too high or too low local concentration of the active ingredients in the pre-gel. Uniform mixing is crucial for ensuring product quality as it enables the active ingredients to be evenly distributed in the colloid structure, making the performance of each part of the product consistent, effectively exerting the efficacy of the active ingredients, and ensuring that the product can stably provide functions such as moisturizing and slow release during use.

[0043] Through the multi-capillary injection system, the addition amount of the active ingredients can be flexibly adjusted according to the product design requirements. The addition amount of the active ingredients accounts for 5 - 50% of the mass of the final colloid product. Different addition amounts can affect the emphasis of the product's efficacy. A high content of active ingredients can be used in products with stronger efficacy to meet the high requirements of specific consumer groups for product efficacy. While a low content of active ingredients is suitable for general care products to provide basic care functions.

[0044] The multi-capillary injection system is an important part of the entire preparation process, closely collaborating with steps such as active ingredient integration, pre-gel preparation, and subsequent shaping and post-treatment. After ultrasonic dispersion or microemulsification integration, the active ingredient forms a stable dispersion or emulsion, which is then precisely injected into the pre-gel through the multi-capillary injection system, laying the foundation for the uniform distribution and stable existence of the active ingredient in the colloidal structure during the subsequent rapid condensation molding and gradient drying and curing processes, jointly achieving the high-quality preparation of the tara gum three-dimensional colloidal product.

[0045] In the shaping and post-treatment steps of the tara gum three-dimensional colloid preparation process of the present invention, rapid condensation molding quickly fixes the colloidal structure, prevents the migration and aggregation of active ingredients, and ensures uniform and stable distribution, which is of great significance for maintaining the stable performance of the product, enhancing film-forming properties and protective effects; gradient drying and curing treatment remove residual solvents, stabilize the colloidal structure, avoid problems caused by solvent residues, improve the storage stability of the product, enable the product to maintain its performance under various conditions, and ensure the reliable quality and safe use of the product.

[0046] The pre-gel injected with the active ingredient passes through the rapid condensation system, and the temperature is quickly reduced at a condensation rate of 50 - 150 °C per minute, enabling the solute to quickly reach the critical concentration and form a three-dimensional colloid and active ingredient complex; rapid condensation can fix the colloidal structure, prevent the migration or aggregation of active ingredients during cooling, ensure the uniform distribution of active ingredients in the colloidal structure, and at the same time quickly form a stable colloidal structure, which helps to maintain the stable performance of the product and improve the product quality. During the gradient drying process, it is first dried in a low-temperature and high-humidity environment to allow the complex to slowly lose water, avoiding surface hardening or internal structure damage caused by rapid drying; then the humidity is gradually reduced and the temperature is increased to continue drying to further remove residual moisture and promote the stability of the colloidal structure; finally, it is cured in a normal-temperature and low-humidity environment to make the product reach the final stable state; the entire gradient drying and curing treatment process can effectively remove residual solvents, stabilize the colloidal structure, improve the storage stability and quality of the product, and ensure that the product maintains good performance during storage and use.

[0047] Preferably, the shaping and post-treatment in step S5 specifically include the following operations: The pre-gel injected with the active ingredient immediately passes through the rapid condensation system, and the condensation rate is controlled at 50 - 150 °C per minute, enabling the solute to quickly reach the critical concentration and form a three-dimensional colloid and active ingredient complex; the complex is then subjected to gradient drying treatment, first dried in a lower temperature and high-humidity environment of 30 - 50 °C and relative humidity of 70 - 90% for 1 - 3 hours, then the humidity is gradually reduced to relative humidity of 30 - 50% and the temperature is increased to 50 - 70 °C to continue drying for 2 - 4 hours, and finally cured in a low-humidity environment of normal temperature and relative humidity of 20 - 40% for 1 - 2 hours to obtain the tara gum three-dimensional colloidal product.

[0048] The condensation rate is a key parameter. Too fast condensation causes stress inside the colloid, affecting the structural stability; too slow condensation allows the active ingredients to migrate or agglomerate, and a uniform composite cannot be formed. The condensation rate range of 50 - 150 °C / minute is determined through experimental optimization. Within this range, rapid and stable molding can be achieved, ensuring product performance. In the low-temperature and high-humidity stage (drying for 1 - 3 hours at 30 - 50 °C and relative humidity of 70 - 90%), appropriate temperature and humidity can cause the composite to lose water slowly and uniformly, preventing structural damage caused by rapid water evaporation. In the medium-temperature and low-humidity stage (raising the temperature to 50 - 70 °C and reducing the humidity to 30 - 50% and drying for 2 - 4 hours), the gradually changing environmental conditions further promote water removal and structural stability. In the normal-temperature and low-humidity curing stage (curing at normal temperature and relative humidity of 20 - 40% for 1 - 2 hours), the product reaches the final stable state under conditions close to the use environment, ensuring stable product performance. The time control in different stages is also important. Too short a time cannot achieve the expected drying and curing effects, and too long a time affects production efficiency or has an adverse impact on the product. It needs to be optimized and adjusted according to the product characteristics and actual production situation.

[0049] Preferably, in the molding and post-treatment of step S5, an extremely fast condensation system is used. This system includes a condensation chamber unit, a cooling medium circulation unit, a temperature control unit, and a condensation rate control unit. The condensation chamber unit includes a condensation chamber and a sealing door. Inside the condensation chamber, there is a sample rack. The sealing door is installed on one side of the condensation chamber. The cooling medium circulation unit includes a cooling medium storage tank, a circulation pump, and a pipeline system. The cooling medium storage tank is equipped with a liquid level monitoring device and a medium replenishment port. The pipeline system connects the cooling medium storage tank, the circulation pump, and the condensation chamber jacket. The temperature control unit includes a temperature sensor, a heater, and a temperature controller. The condensation rate control unit includes a flow regulating valve and a pressure monitoring device.

[0050] During the molding and post-treatment of the tara gum three-dimensional colloid, the pre-gel mold injected with the active ingredients is placed on the sample rack in the condensation chamber, and the sealing door is closed. The temperature control unit controls the operation of the cooling medium circulation unit according to the preset temperature curve and condensation rate. The circulation pump transports the cooling medium from the storage tank to the condensation chamber jacket. By adjusting the opening degree of the flow regulating valve, the flow rate of the cooling medium is controlled, so that the pre-gel rapidly cools down at the specified condensation rate to form a three-dimensional colloid and active ingredient composite. During the condensation process, the temperature sensor continuously monitors the temperature of the pre-gel and the cooling medium. The temperature control unit adjusts the power of the heater and the flow rate of the cooling medium according to the temperature signal to ensure precise control of the condensation process. After condensation is completed, according to the requirements of subsequent processes, the composite is subjected to gradient cooling or heat preservation treatment through the temperature control unit, and then taken out for subsequent drying and curing operations to obtain a high-quality tara gum three-dimensional colloid product.

[0051] In summary, the present invention has the following beneficial effects: 1. Compared with common moisturizing ingredients such as glycerin and hyaluronic acid, the tara gum three-dimensional colloid of the present invention is of natural origin, non-toxic, has no side effects, and has good biocompatibility, which conforms to the concept of green environmental protection. Its three-dimensional colloid has stable physical and chemical properties and flexible forming and processing. The tara gum three-dimensional colloid of the present invention has a more lasting and stable moisturizing effect, and can form a uniform and certain-strength protective film on the skin or hair surface. The galactomannan extracted from the endosperm of tara seeds has a specific molecular structure, and its three-dimensional structure can provide better water-locking ability. At the same time, as a carrier, the colloid structure can effectively encapsulate and disperse multiple active ingredients such as vitamin C and ceramide, protect the active ingredients from external environmental factors such as oxidation and light, and at the same time control the release rate of the active ingredients to achieve a sustained release effect, improving the utilization rate of the active ingredients and making better use of the active ingredients than conventional colloids; 2. Compared with conventional colloids containing chemically synthesized ingredients or having a single performance, the tara gum three-dimensional colloid provided by the present invention uses the endosperm of tara seeds as a natural raw material. Its unique structure of galactomannan endows the colloid with excellent moisturizing, sustained release and film-forming properties. The preparation process integrates advanced technologies and precisely controls parameters, ensuring product quality and sustainability. It is widely applicable in multiple fields, and the colloid structure and multiple active ingredients synergistically enhance the effect, better meeting the needs of consumers for natural and highly effective products; 3. The present invention integrates a variety of traditional and modern technical means such as solvent extraction, high-pressure reaction, ultrasonic microemulsification, multi-capillary injection and rapid condensation into a preparation process, forming a relatively complete, efficient and unique preparation process for tara gum three-dimensional colloid, improving production efficiency and providing more possibilities for optimizing product performance; by strictly controlling process parameters, flexibly adjusting the properties of the colloid according to different product requirements, tara gum three-dimensional colloid products with different functional focuses are prepared to meet the diverse needs of the market, while ensuring the reliability of product quality; 4. Different from the traditional direct addition of active ingredients, the preparation process of the tara gum three-dimensional colloid of the present invention uses ultrasonic dispersion or microemulsification technology to pretreat the active ingredients and then inject them into the pre-gel, better realizing the dispersion and sustained release of the active ingredients, improving the utilization rate of the active ingredients and prolonging the duration of the product's efficacy; ultrasonic-assisted extraction uses ultrasonic cavitation to break the plant cell wall and improve the extraction rate of galactomannan; microemulsification technology enables the active ingredients to be better dispersed in the colloid; multi-capillary injection ensures the uniform injection of the active ingredients into the pre-gel; rapid condensation quickly fixes the colloid structure, ensuring stable product performance, comprehensively improving production efficiency and product quality, and realizing the efficient extraction of raw materials, the uniform dispersion of active ingredients and the precise construction of the colloid structure.

[0056] Example 2

[0057] S1 Raw material pretreatment: Take mature Caesalpinia spinosa seeds, remove impurities, separate the endosperm, wash, dry, and crush them to a particle size of 50 μm to obtain pretreated Caesalpinia spinosa seed endosperm powder. S2 Galactomannan extraction: Take a certain amount of crushed seed endosperm powder, mix it with water or an ethanol solution with a volume fraction of 50% at a solid-liquid ratio of 1:5 g / mL. During the mixing process, use a mechanical stirrer to stir at a low speed of 100 rpm for 5 minutes to ensure full contact between the powder and the solvent and form a uniform suspension or mixture.

After centrifugation, take the supernatant to obtain a clear galactomannan extract. Transfer the fine-filtered galactomannan extract to a rotary evaporator in a vacuum concentration device, concentrate it under the condition of a pressure of 0.05 MPa, control the temperature at 40 °C, and stop the concentration when the solution volume is reduced to 1 / 3 of the original to obtain a high-purity galactomannan solution with a galactomannan content of 60%. Steps S3 Three-dimensional colloid pre-gel preparation, S4 Active ingredient integration and addition, and S5 Molding and post-treatment are the same as in Example 1 to obtain a Caesalpinia spinosa gum three-dimensional colloid product.

[0058] Example 3

[0059] Steps S1 Raw material pretreatment and S2 Galactomannan extraction are the same as in Example 1; S3 Three-dimensional colloidal pre-gel preparation: Transfer the high-purity galactomannan solution to a high-pressure reactor, add an appropriate amount of water or buffer solution as a solvent so that the final concentration of galactomannan is 5%, and seal the reactor; Under the condition of a stirring speed of 300 rpm, raise the temperature in the reactor to 70 °C at a heating rate of 2 °C per minute, and at the same time apply a pressure of 0.1 MPa, and keep stirring at this temperature and pressure for 1 hour until the galactomannan is completely dissolved to form a uniform and transparent pre-gel solution; After dissolution, transfer the pre-gel solution to a constant-temperature circulation system through a pipeline, keep the temperature in the pipeline at 40 °C, and let the solution circulate in the pipeline for 30 minutes to promote the further stabilization and structural optimization of the pre-gel, and obtain a three-dimensional colloidal pre-gel; S4 Integration and addition of active ingredients: Using a multi-capillary injection system, inject the pre-selected and ultrasonically dispersed or microemulsified active ingredient vitamin E (i.e., VE) into the pre-gel, and control the injection pressure at 0.3 MPa; S5 Molding and post-treatment: The pre-gel injected with the active ingredient is molded through an ultra-rapid condensation system, and the condensation rate is controlled at 50 °C per minute to make the solute reach the critical concentration, forming a complex of three-dimensional colloid and active ingredient. After gradient drying and curing treatment, a tara gum three-dimensional colloid product is obtained.

[0062] Perform performance tests on the tara gum three-dimensional colloid products obtained in Examples 1-3, the commercially available moisturizing product in Comparative Example 1, and the commercially available moisturizing product prepared from ordinary tara gum in Comparative Example 2, and the results are as follows.

[0063] 1. Film-forming performance test The tara gum three-dimensional colloid prepared in Example 1 was coated on a glass slide. After natural drying, the surface morphology of the film was observed using a cryo-scanning electron microscope (CRYOSEM). The results are shown in Figure 1 . The figure shows that the surface of the formed film is flat, uniform, with an appropriate thickness, and has good continuity and density. This indicates that the tara gum three-dimensional colloid can spread evenly and form a tight structure during the film-forming process. This good film-forming performance enables it to effectively cover and protect the skin or hair surface when applied, prevent moisture loss, and at the same time provide a stable carrier for active ingredients, facilitating the attachment and function of active ingredients on the skin or hair surface.

[0064] 2. Structural stability test The microstructures of the tara gum three-dimensional colloids prepared in Examples 1-3 were observed. The micro-morphology of the colloids was observed using a cryo-scanning electron microscope. The results are shown in Figures 2 - 4 . The colloids in the figure all exhibit a uniform and dense three-dimensional network structure without obvious holes or agglomeration phenomena. This indicates that during the preparation process, each process step effectively controls the formation of the colloid, enabling the galactomannan molecules to arrange orderly and interact with each other to form a stable three-dimensional structure. The uniform and dense structure helps to maintain the physical stability of the colloid, preventing the colloid from undergoing structural damage or component separation during storage and use, thus ensuring the performance consistency and reliability of the product. After being placed for 1 month, 3 months, and 6 months under different storage conditions such as room temperature, 4 °C, 25 °C / 60% RH, and 37 °C / 75% RH, the colloid structure was observed again and found that the structure remained basically unchanged, indicating that the tara gum three-dimensional colloid has good resistance to environmental interference and can adapt to different temperature and humidity conditions. During long-term storage, the stability of the colloid structure is crucial for the shelf life and use effect of the product. A stable structure can ensure the stable existence of active ingredients in the colloid and enable them to be released and function as expected during use, providing strong support for the long-term effectiveness of the product in practical applications.

[0065] 3. Moisture retention performance test Select a number of volunteers aged between 25 and 45 with different degrees of skin dryness. Apply the tara gum three-dimensional colloid products prepared in Examples 1-3, the commercially available ordinary moisturizing product in Comparative Example 1, the moisturizing aquatic product prepared from commercially available ordinary tara gum in Comparative Example 2, and no product (blank control) on the same area of the inner side of their clean arms. Use a skin moisture tester to measure the skin moisture content before application and at 1, 3, 6, 12, and 24 hours after application, and record the average value of each group of data. The results are shown in Table 1. The detection results of the skin moisture content of each group show that the moisture content of the skin parts coated with the colloid of the present invention is significantly higher than that of the ordinary moisturizing product, the moisturizing aquatic product prepared from ordinary tara gum, and the blank control at each time point, and can maintain a relatively high moisture content within 24 hours, indicating that the tara gum three-dimensional colloid prepared by the present invention has excellent moisturizing performance, can effectively improve the degree of skin hydration, and maintain the moist state of the skin.

[0066] Table 1 Summary of the detection results of the skin moisture content of each group (unit: %)

[0067] Among them, before application, the skin moisture content of each example, comparative example, and blank control was relatively close, between 32.81% and 33.02%, which provided basic data for subsequent comparison and indicated that the skin states of the volunteers were comparable at the start of the experiment; 1 hour after application, the skin moisture contents of Examples 1-3 reached 58.25%, 58.68%, and 59.00% respectively, which were significantly higher than 50.65% of Comparative Example 1, 55.26% of Comparative Example 2, and 28.36% of the blank control. This shows that the tara gum three-dimensional colloid can quickly supplement moisture to the skin, and the supplementation effect is significantly better than that of the commercially available ordinary moisturizing product and the moisturizing aquatic product prepared from commercially available ordinary tara gum. The reason is that the special structure of galactomannan in the colloid can interact with the stratum corneum of the skin to form a moisturizing barrier, and at the same time, the combined moisturizing components such as hyaluronic acid play a powerful water absorption and water locking function, and the special slow-release system prolongs the action time of the effective moisturizing components; as time goes by, at time points such as 3 hours, 6 hours, 12 hours, and 24 hours, the skin moisture contents of Examples 1-3 are higher than those of Comparative Example 1, Comparative Example 2, and the blank control. At 24 hours, the skin moisture contents of Examples 1-3 still remained between 37.93% and 38.62%, while that of Comparative Example 1 dropped to 33.89%, that of Comparative Example 2 dropped to 34.05%, and that of the blank control was only 11.02%. This shows that the tara gum three-dimensional colloid has a lasting moisturizing effect, can maintain the skin moisture content for a long time, and prevent the skin moisture from losing too fast. The persistence of its moisturizing effect benefits from the good water retention ability of the colloid structure and the slow-release effect of the active ingredients. The unique slow-release system of the tara gum three-dimensional colloid of the present invention continuously provides long-term moisturizing support for the skin.

[0068] 4. Sustained Release Test of Active Ingredients The tara gum three-dimensional colloid products prepared in Examples 1-3, the commercially available ordinary moisturizing product in Comparative Example 1, and the moisturizing aquatic product prepared from commercially available ordinary tara gum in Comparative Example 2 were respectively placed in a buffer solution simulating the skin environment. Samples were taken at time points such as 1, 3, 6, 12, and 24 hours, and the content of vitamin E, i.e., VE, in the solution was determined by high performance liquid chromatography (HPLC). The test results are shown in Table 2. The results indicate that VE in the tara gum three-dimensional colloid product prepared in the examples of the present invention is slowly released from the colloid and continuously released within 24 hours. Compared with the commercially available ordinary moisturizing product in Comparative Example 1 and the moisturizing aquatic product prepared from commercially available ordinary tara gum in Comparative Example 2, the release rate is more stable, indicating that the three-dimensional colloid of the present invention has good sustained release ability of active ingredients and can extend the action time of active ingredients.

[0069] Summary of VE Content Detection Results in Solutions of Each Group (Unit: μg / mL)

[0070] Among them, at 1 hour, the VE release amounts of Examples 1-3 were 10 μg / mL, 9 μg / mL, and 10 μg / mL respectively, slightly lower than 12 μg / mL of Comparative Example 1 and 11 μg / mL of Comparative Example 2. Due to the structure of the tara gum three-dimensional colloid playing a certain role in encapsulating and controlling the sustained release of the active ingredient, the initial release was relatively slow; as time increased, at time points such as 3 hours, 6 hours, 12 hours, and 24 hours, the VE release amounts of Examples 1-3 continued to increase, and the release rate was relatively stable. The VE release amounts of Examples 1-3 all reached 38 μg / mL at 24 hours, while the release rates of Comparative Example 1 and Comparative Example 2 decreased significantly after 6 hours and were only 8 μg / mL and 9 μg / mL at 24 hours. This indicates that the tara gum three-dimensional colloid can achieve slow and continuous release of active ingredients, keep a certain effective concentration of active ingredients for a long time, thereby extending its action time and improving the utilization rate of active ingredients. This sustained release performance is particularly important for skin care ingredients that need to act for a long time (such as antioxidant VE), and can continuously exert its antioxidant and other effects to provide more lasting protection for the skin.

[0071] Based on the analysis of the above experimental data, the tara gum three-dimensional colloid of the present invention performs excellently in film-forming performance, structural stability, moisturizing performance, and sustained release performance of active ingredients, and has obvious advantages compared with commercially available ordinary moisturizing products, providing strong data support and theoretical basis for its application in cosmetics and personal care products.
