Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1 to 8 This invention provides a technical solution: a hand cream formula. The hand cream formula comprises osmanthus, rose, beeswax, tea oil, high-proof liquor, and comfrey oil. The amount of osmanthus is 1 to 7 grams, the amount of rose is 1 to 5 grams, the amount of beeswax is 2 to 8 grams, the amount of high-proof liquor is 10 to 40 ml with an alcohol content of 52% to 65%, the amount of tea oil is 80 to 120 ml, and the amount of comfrey oil is 1 to 5 grams. In a preferred embodiment, the amounts are: 3 grams of osmanthus, 3 grams of rose, 5 grams of beeswax, 20 ml of high-proof liquor with an alcohol content of 55%, 100 ml of tea oil, and 3 grams of comfrey oil.
[0019] For ease of understanding, in this article, "soaking system" refers to the mixed system formed by herbal fragments and high-proof liquor during the liquor soaking stage; "herbal tea oil liquid" refers to the oil phase liquid obtained after oil soaking, filtration to remove herbal residues, and volume adjustment; "mixed system" refers to the oil-wax system formed by adding beeswax to the herbal tea oil liquid and mixing it through a water bath. The purple gromwell oil in this scheme is extracted from purple gromwell.
[0020] S1. Disinfection preparation: In one embodiment, step S1 is used to establish hygienic and moisture control conditions for the preparation process to avoid the introduction of impurities, moisture or microorganisms that could cause fluctuations in the texture of the finished product or a decrease in storage stability.
[0021] S1.1 Scalding and Drying of Preparation Tools: The preparation tools include a beaker, a glass rod, and a small spoon. The beaker, glass rod, and small spoon are scalded in boiling water to clean and sterilize the tool surfaces. After scalding, the tools are removed and allowed to air dry naturally. To ensure the stability of the subsequent oil phase system, the criteria for drying are: no visible water droplets or obvious water film residue on the tool surface, and the inner wall and contact surface of the tool are dry. If residual water droplets remain on the tool surface, the drying time can be extended, or the water droplets can be gently absorbed with a clean paper towel (to avoid fiber shedding and contamination).
[0022] S1.2 Ethanol Disinfection and Drying of Empty Containers: Empty hand cream tubes or boxes used for filling are disinfected with ethanol and dried before filling; in a preferred embodiment, the ethanol is 75% by volume. The disinfection operation may include wiping or immersing the inner wall, opening, and inner side of the cap of the empty hand cream tube or box to ensure that the ethanol is in full contact with the surface of the mixture to be mixed; then allowing it to evaporate naturally. The criteria for drying may be: no visible droplets or obvious residual ethanol film on the inner wall of the container, so as to reduce the impact of ethanol residue on the subsequent ointment structure and odor stability. Note: This step is not limited to using a specific disinfection method, only requiring that the "tools and containers are clean and free of visible moisture residue" to support the homogeneity and repeatability of the subsequent oil phase system.
[0023] S2. Herbal pretreatment and liquor soaking: In one embodiment, step S2 is used to break down the structure of osmanthus and rose flowers and soak them in solvent, so that the herbal components form a stable soaking system under the action of high-proof liquor, creating conditions for subsequent oil phase support.
[0024] S2.1 Herbal Raw Material Processing: Take osmanthus and rose petals, remove the calyxes, and then crush them to form herbal fragments. The degree of crushing should be such that "the herbal raw materials are clearly fragmented, the surface area is increased, and they are easily wetted by solvents." Avoid over-crushing, which may increase the filtration burden or allow fine powder residue to enter the oil phase and affect the texture.
[0025] S2.2 Adding high-proof liquor to form an infusion system: Add 10 ml to 40 ml of high-proof liquor (52% to 65% alcohol) to the herb fragments, ensuring the herb fragments are fully soaked and forming an infusion system; in a preferred embodiment, continue soaking for 24 hours. During the soaking process, the infusion system can be temporarily stored in a covered container to reduce volume or concentration fluctuations caused by evaporation; and gentle shaking or stirring can be performed during soaking to ensure more even distribution of the herb fragments and avoid unsoaked areas. Criteria for determining the completion of soaking may include: the herb fragments are generally soaked, there are no obvious dry agglomerates in the system, and the color or odor of the solvent phase shows a stable trend (this criterion is only for operational observation and is not a mandatory condition).
[0026] S3, Oil Immersion: In one embodiment, step S3 is used to introduce the oil phase as a carrier into the immersion system, allowing the transferable components in the immersion system to further enter the oil phase, forming an oil phase base for ointment formation. After completing step S2, the immersion system obtained in step S2 is used as the immersion system, and tea oil is added to the immersion system and immersion continues. In one embodiment, the volume of tea oil added is 80 ml to 120 ml; in a preferred embodiment, immersion continues for 3 days after the addition of tea oil. During the continued immersion, the system can be intermittently and slightly stirred or the container rotated to ensure more sufficient contact between the herbal fragments and the oil phase, reducing uneven extraction caused by local deposition of herbal fragments. The criteria for determining the completion of oil immersion may include: the color of the oil phase tends to be stable, the herbal fragments in the system are in sufficient contact with the oil phase, and there is no obvious unmixed free layer of white wine in the oil phase (this criterion is a process observation standard used to assist those skilled in the art in implementation).
[0027] S4. Filtration and Volume Adjustment: In one embodiment, step S4 is used to remove herbal residues and control the volume range of the herbal tea oil liquid to ensure a stable oil-wax ratio window, thereby improving the consistency of subsequent ointment formation.
[0028] S4.1 Filtration and Removal: Filter the soaking system from step S3 to remove herbal residue, obtaining filtered herbal tea oil. Filtration can be performed using double-layer gauze or a mesh filter. Natural drip filtration can be used during filtration to reduce fine powder penetration, or the residual liquid on the filter media can be gently squeezed to reduce the loss of the effective oil phase. To avoid introducing moisture during filtration, the filter equipment should be kept dry before use. After filtration, the herbal tea oil should be in a continuous oil phase state and free of large, visible herbal residue.
[0029] S4.2 Volume Control Window: Add tea oil to the herbal tea oil solution to adjust the volume, making the volume of the herbal tea oil solution between 80 ml and 120 ml. The purpose of volume control is to compensate for the volume loss caused by filtration, so that when beeswax is added and heated for mixing, the oil phase volume is within a stable window, thereby reducing the fluctuation of the oil-wax ratio between different batches due to "differences in filtration loss".
[0030] After filtration and adding tea oil to make up the volume, add comfrey oil to the herbal tea oil solution and mix well to ensure that the comfrey oil is evenly distributed in the herbal tea oil solution. This provides a stable and consistent oil phase basis for the subsequent water-cooled heating and mixing of beeswax.
[0031] Criteria for determining the state after volume adjustment may include: the total volume of the herbal tea oil solution falling within the range of 80 ml to 120 ml, and the oil phase appearing continuous without obvious layering or suspended solid agglomeration.
[0032] S5. Beeswax melting and mixing and water bath heating: In one embodiment, step S5 is used to introduce beeswax into the herbal tea oil liquid and soften, disperse and mix it under water bath heating to form a stable oil-wax system, laying the structural foundation for subsequent ointment formation.
[0033] S5.1 Adding materials to form a mixed system: Place the herbal tea oil liquid in a clean, anhydrous glass bottle, and add 2 to 8 grams of beeswax to the glass bottle to form a mixed system to be mixed. To ensure sufficient contact between the beeswax and the oil phase, the beeswax can be added in a dispersed manner or cut into small pieces before adding (this is a description of the operation method and does not constitute a limitation on the form of beeswax).
[0034] S5.2 Assembly and heating control of water-insulated heating: Place the glass bottle in a pot and add cold water. The liquid level of the cold water is half the height of the glass bottle. The mixture is heated by water-insulated heating. In a preferred embodiment, the mixture is heated to 40°C to 50°C and maintained for 30 minutes.
[0035] The advantages of water-insulated heating are: it achieves gentle and uniform heating through water medium heat transfer, reduces fluctuations in oil phase quality caused by localized overheating, and improves the consistency of beeswax softening and dispersion. During the holding phase, a glass rod can be used to slowly stir the mixture to ensure that the beeswax is more evenly dispersed in the oil phase and forms a continuous oil-wax system; stirring should be done in a manner that "does not introduce obvious air bubbles or foreign impurities".
[0036] Definition of "Melting and Mixing": In this invention, "melting and mixing" does not mean that beeswax must reach a completely transparent liquid state. Rather, it refers to the softening, dispersion, and flow of beeswax in the oil phase within a mild temperature window of water-cooled heating, forming a stable and homogeneous oil-wax system after stirring. One purpose of controlling the temperature between 40°C and 50°C is to avoid fluctuations in volatile components related to high-proof liquor, heat-induced deterioration of herbal components, and instability in the texture of the finished product caused by excessively high temperatures, thereby ensuring product quality consistency and preparation safety.
[0037] S5.3 Cooling and Secondary Stabilization Soaking: After heating is completed, the heat is turned off and the mixture is cooled. In a preferred embodiment, after cooling, the mixture is soaked for another 24 hours to further stabilize the internal structure of the mixture. This stabilization stage helps the oil-wax system transition from a "heated and homogenized state" to a "structurally stable state," reducing the probability of localized uneven thickness during the subsequent filling and paste-forming process.
[0038] S6. Filling and Cooling to Form a Cream: In one embodiment, step S6 is used to complete filling within a suitable flow window and achieve cream-like shaping through room temperature cooling. While the mixture obtained in step S5 is not completely solidified, it is poured into an empty container sterilized in step S1; subsequently, it is cooled to complete solidification at room temperature and then sealed to obtain hand cream. "Not completely solidified" can be understood as the stage where the mixture is still flowable and can be smoothly filled; filling at this stage reduces the secondary thermal history effects caused by reheating after complete solidification and reduces texture fluctuations caused by repeated damage to the oil and wax structure. Criteria for determining the state of complete solidification after filling at room temperature include: the hand cream in the container no longer flows, the surface morphology is stable, and there is no obvious layering. During sealing, the cap should be reliably closed to reduce the risk of volatilization and contamination during storage.
[0039] Example 1 I. Raw materials and dosage: The raw materials and dosage of the hand cream formula used in this embodiment are as follows: 3 grams of osmanthus, 3 grams of rose, 5 grams of beeswax, 20 ml of high-proof liquor with an alcohol content of 55 degrees, 100 ml of tea oil, and 3 grams of comfrey oil.
[0040] II. Equipment Preparation: Prepare beakers, glass rods, small spoons, clean and anhydrous glass bottles, double-layered gauze or filter screens, empty hand cream tubes or hand cream boxes, measuring cylinders, and a balance for weighing.
[0041] III. Preparation steps: 1) Sterilization and drying: Scald the beaker, glass rod and small spoon with boiling water and then air dry until there are no visible water droplets on the surface of the tools; sterilize the empty hand cream tube or hand cream box with 75% ethanol by volume and then air dry until there are no visible liquid droplets left on the inner wall of the container.
[0042] 2) Herbal pretreatment: Take osmanthus and rose flowers, remove the calyx and crush them to form herbal fragments; the herbal fragments should be "visibly broken and easy to soak" to avoid excessive crushing that will make filtration difficult.
[0043] 3) Soaking in liquor: Place the herb fragments in a clean, dry glass bottle, add 20 ml of high-proof liquor, so that the herb fragments are fully soaked in the liquor and form a soaking system; soak at room temperature for 24 hours, during which the container can be shaken slightly intermittently to enhance the uniformity of the system.
[0044] 4) Oil soaking: After the white wine soaking is completed, add tea oil to the soaking system and continue soaking until the total volume of tea oil reaches 100 ml; continue soaking at room temperature for 3 days. During the soaking period, the container can be turned slightly intermittently to enhance the contact between the oil phase and the herbal fragments.
[0045] 5) Filtration and Volume Adjustment: Use double-layer gauze or a filter screen to remove herbal residues and obtain filtered herbal tea oil solution. Measure the volume of the filtered herbal tea oil solution and add tea oil to adjust the volume to 100 ml. After filtration, obtain the herbal tea oil solution and adjust the volume with tea oil to maintain 100 ml. Then add 3 grams of comfrey oil and mix well. Next, add 5 grams of beeswax and heat in a water bath to mix.
[0046] 6) Add beeswax and mix by double heating: Add 5 grams of beeswax to the herbal tea oil solution after it has been brought to a final volume, and place the mixture in a clean, anhydrous glass bottle; place the glass bottle in a pot and add cold water, so that the water level is half the height of the glass bottle; use a double heating method, heat over low heat to 45°C and maintain for 30 minutes, stirring slowly with a glass rod during this time to promote the softening, dispersion and even mixing of the beeswax in the oil phase; turn off the heat and let it cool, then continue to soak for 24 hours.
[0047] 7) Filling and cooling to form cream: While the mixture is not completely solidified and is still fluid, pour it into sterilized and dried empty hand cream tubes or boxes; after cooling to room temperature until completely solidified, seal to obtain the finished hand cream.
[0048] IV. Critical State Criteria Dryness criteria for tools and containers: No visible water droplets or ethanol droplets remain; Criteria for the formation of the soaking system: The herbal fragments are completely soaked in the liquor, with no obvious dry agglomerates; Criteria for successful filtration: No large, visible residues were found in the herbal tea oil solution; Criterion for uniform mixing: After heating and stirring, the system appears continuous with no obvious beeswax lumps floating; Criteria for gel formation: The contents no longer flow after cooling to room temperature, and there is no obvious layering in appearance.
