Description

Technical Field

[0001] This invention relates to the field of cosmetic polypeptide active ingredient preparation technology, specifically a method for preparing a polypeptide composition with anti-wrinkle effects. Background Technology

[0002] Facial wrinkles are divided into dynamic expression lines and static aging lines. Single peptides can only act on a single pathway, resulting in limited anti-wrinkle effects. Currently, the mainstream anti-wrinkle active peptides on the market mainly include botulinum toxin-like peptides, which improve wrinkles through four pathways: inhibiting neurotransmitter release, promoting dermal collagen synthesis, repairing the skin barrier, and relaxing muscle contraction. The industry's conventional approach is to simply combine multiple peptides with polyols and moisturizers to create a peptide complex stock solution, which is then directly added to skincare products, relying on the synergistic effect of peptides to enhance anti-wrinkle efficacy. Existing conventional preparation processes mostly use a single-reactor one-step feeding method, simultaneously dissolving water, moisturizers, and peptide powder at high temperatures. The equipment only uses a common single-layer stirred reactor, lacking independent peptide pre-dissolution, precise temperature control, and online automatic pH adjustment modules. To overcome the shortcomings of traditional one-step peptide compounding processes, such as high activity loss, easy peptide precipitation, difficulty in pH stability, poor transdermal effect, low integration of production equipment, and high product irritation, this invention designs a dedicated segmented temperature-controlled peptide preparation device, providing two improved compounding processes (liposome encapsulation enhancement process and mild natural plant small molecule peptide compounding process). Through independent pre-dissolution, PLC segmented temperature control, online pH linkage adjustment, and aseptic low-temperature filtration integrated design, it solves industry pain points such as high-temperature degradation, aggregation and precipitation, and easy oxidation during storage of peptides. At the same time, it takes into account transdermal absorption and suitability for sensitive skin, realizing the preparation of anti-wrinkle peptide compositions with high activity, high stability, and continuous industrial production. Therefore, a method for preparing peptide compositions with anti-wrinkle effects is needed.

[0003] Currently used peptide compositions suffer from several drawbacks: high temperatures cause peptide bonds to break, copper peptides to oxidize and become ineffective, resulting in low activity retention; direct contact of peptide powder with water leads to agglomeration and the formation of insoluble microparticles, resulting in poor product transparency; the pH of the system fluctuates greatly due to manual adjustment, shortening the shelf life; free peptides have difficulty penetrating the stratum corneum, resulting in weak deep anti-wrinkle effects; synthetic peptide systems are highly irritating and unsuitable for sensitive skin; traditional equipment lacks integrated modules for segmented temperature control, independent pre-dissolution, and aseptic filtration, leading to poor batch stability and an inability to achieve integrated production of liposome encapsulation or plant peptide compounding. Summary of the Invention

[0004] The purpose of this invention is to provide a method for preparing a polypeptide composition with anti-wrinkle effects, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for preparing a polypeptide composition with anti-wrinkle effects includes a core anti-wrinkle polypeptide component, moisturizing and stabilizing excipients, a complete standard preparation process, and a natural plant compound polypeptide process.

[0007] Preferably, the core anti-wrinkle polypeptide components include acetyl hexapeptide-8: 0.1% to 0.5%, palmitoyl tripeptide 1 + tetrapeptide 7: 0.08% to 0.3%, blue copper peptide GHK-Cu: 0.02% to 0.15%, and snake venom-like peptide: 0.05% to 0.2%.

[0008] Preferably, the moisturizing and stabilizing excipients include polyols, active agents, stabilizers, mild preservatives, and solvents.

[0009] Preferably, the complete standard preparation process includes aqueous matrix preparation, separate pre-dissolution of peptides, low-temperature compounding and pH adjustment, maturation, and filtration.

[0010] Preferably, the natural plant compound polypeptide process includes plant peptide preparation, formulation optimization, and feeding operations.

[0011] A method for preparing a polypeptide composition with anti-wrinkle effects includes the following steps:

[0012] S1. Start the heating cycle, add deionized water to the main reactor, and stir at 300 r / min to raise the temperature to 48-50℃. Add 1,3-butanediol, glycerol, panthenol, disodium EDTA, and sodium low molecular weight hyaluronic acid sequentially through the top feed port, and stir at a constant temperature for 15-20 min until the materials are completely dissolved. Start the buffer addition unit, monitor the pH in real time with the online pH probe, and add citric acid / sodium citrate buffer solution to adjust the pH of the system to 5.2-6.2. After maintaining the temperature and stabilizing for 10 min, turn off the heating circuit, turn on the cooling circulation system, and quickly cool the materials in the reactor to below 35℃. Keep the reactor at this temperature and let it stand for later use.

[0013] S2. Add 5% of the formulation of 1,3-butanediol to the peptide premixing tank, maintain the temperature of the refrigeration system at 25°C, and start the magnetic stirrer at 200 r / min. Sequentially add acetyl hexapeptide-8, palmitoyl tripeptide-1 / palmitoyl tetrapeptide-7 complex, dipeptide diaminobutyryl benzylamide diacetate, and finally add blue copper peptide GHK-Cu. Continue stirring for 20-25 min until the liquid is completely clear and free of precipitate to obtain the peptide premix. Start the delivery diaphragm pump and set the pipeline flow regulating valve to control the drip rate.

[0014] S3. Maintain the temperature inside the main reactor at 30–35°C, and adjust the stirring speed to 250 r / min. Add the peptide solution from the pre-dissolved peptide tank to the main reactor at a uniform rate through the dropper, with a total droppering time ≥8 min. After all drops are added, maintain the temperature and stir for 25–30 min to ensure uniform dispersion of the peptides. Add the p-hydroxyacetophenone + 1,2-hexanediol preservative mixture through the feed port and stir for 10 min to fully dissolve. Monitor the pH online and add a small amount of buffer solution to fine-tune the pH to 5.3–6.0.

[0015] S4. Continue to slowly cool down the cooling system at a rate of 5℃ / h, and stir at a low speed until the system temperature drops to 25℃. Maintain constant temperature for 30 minutes to eliminate internal stress. Open the discharge valve at the bottom of the main vessel. The material flows through the pre-precision filter and the 0.22μm polyethersulfone sterile filter membrane assembly under negative pressure to remove impurities and microorganisms.

[0016] S5. Finally, hydrolyzed collagen, ginseng protein, and Dendrobium officinale protein are fed into an enzymatic hydrolysis tank for alkaline enzymatic hydrolysis. The ultrafiltration equipment retains peptides with a molecular weight <1000Da and desaltes them. The spray drying unit produces plant polypeptide powder, reducing the original synthetic polypeptide feed amount by 50%. The plant polypeptide powder and synthetic polypeptide powder are fed together into a polypeptide pre-dissolving tank for simultaneous butylene glycol pre-dissolving. After filtration, the material is directly filled into a light-proof brown sterile container through a sterile filling interface and stored in a sealed, light-proof container.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] An improved design employs a multi-tank independent temperature control system to separate the high-temperature matrix preparation and peptide feeding. PLC over-temperature interlock protection prevents peptide degradation and inactivation at high temperatures. A separate pre-dissolving tank ensures complete pre-dissolution of peptides, preventing aggregation and precipitation upon direct water introduction. An online real-time pH-linked buffer metering pump maintains stable peptide activity within a suitable pH range throughout the process. Furthermore, a lipid homogenization system enables peptide liposome encapsulation, enhancing transdermal absorption and the antioxidant stability of copper peptides. A 0.22μm sterile filtration unit at the end eliminates the need for high-temperature sterilization, ensuring peptide activity at low temperatures throughout the process. The finished product carries no risk of preservative irritation. Attached Figure Description
