Abstract
Description
Technical Field
[0001] This invention relates to the field of bioactive ingredient preparation and cosmetic raw material technology, specifically a preparation process for a targeted skincare-type white snail active complex. Background Technology
[0002] Snail-derived active ingredients have become core ingredients in the high-end beauty industry due to their excellent skin repair, moisturizing, and anti-aging effects. Among them, snail enzymes can promote cell metabolism and accelerate the repair of damaged tissues; glycosaminoglycans have powerful water-locking, moisturizing, soothing, and anti-inflammatory effects; and growth factors can stimulate collagen regeneration and reduce fine lines and wrinkles. The three types of ingredients work synergistically to achieve a full-chain skincare effect of "repair-moisturizing-anti-aging".
[0003] However, existing snail active ingredient extraction and application technologies face several bottlenecks: First, traditional extraction processes often employ high-temperature extraction or single enzymatic hydrolysis, leading to the inactivation of a large number of heat-sensitive growth factors and the destruction of glycosaminoglycan structures, preventing the simultaneous and efficient enrichment of the three core components; second, the extracts often contain residual large-molecule allergenic proteins, which can easily trigger allergic reactions in people with sensitive skin, limiting the product's applicability; third, the active ingredients have poor stability and are prone to oxidation and degradation during room temperature storage, resulting in a decrease in the efficacy of beauty products; fourth, most processes are not optimized for the skin feel requirements of beauty products, and the addition of extracts can easily make the product sticky, affecting the user experience.
[0004] While some improved processes for snail extract exist internationally, they mostly focus on extracting single components, failing to achieve synergistic enrichment and stable compatibility of the three core components. For example, a South Korean company used a low-temperature enzymatic hydrolysis process to extract snail enzymes, achieving an extraction rate of 85%, but the loss rate of glycosaminoglycans and growth factors exceeded 30%. A French laboratory used membrane separation technology to purify snail extracts, reducing sensitization, but failing to solve the problem of storage stability of active ingredients. Therefore, developing a process for preparing a white snail active complex that can simultaneously achieve high extraction rate, high purity, high stability, and low sensitization, and is suitable for the application needs of beauty products, has become a key technology that the industry urgently needs to overcome. Summary of the Invention
[0005] The technical problem to be solved by this invention is to overcome the above-mentioned technical defects.
[0006] To address the above problems, the technical solution of this invention is: a preparation process for a targeted skincare-enhancing white jade snail active complex, comprising the following steps: Step S1, Raw Material Pretreatment and Low-Temperature Fractional Extraction: Select healthy, live white jade snails weighing 60-80g and place them in an environment with a temperature of 20-22℃ and a relative humidity of 65%-70% for 2-3 days without food. Aseptically separate the soft tissue and foot gland secretions, and mix them at a mass ratio of soft tissue:foot gland secretions:sterile ice water = 3:1:10. Adjust the pH of the system to 6.5-7.0. First, extract the snails by stirring at low speed at 4℃ for 2 hours to extract glycosaminoglycans and growth factors. Then, raise the temperature to 15℃ and continue stirring for 1 hour to extract snail enzymes. Combine the two extracts to obtain a mixed extract. Step S2, Ultrasonic-Assisted Targeted Hydrolysis with Compound Enzyme: Add a compound enzyme preparation to the mixed extract. The compound enzyme preparation consists of papain and hyaluronidase in a mass ratio of 2:1, with a total enzyme activity ≥1000 U / mg. The amount of enzyme added is 1.2%–1.8% of the total weight of the raw materials. Adjust the pH of the system to 6.0–6.5, raise the temperature to 45°C, and apply 20kHz ultrasound-assisted treatment at a power of 300W, working for 5 seconds and then intermittently for 3 seconds, for isothermal hydrolysis for 3.5–4 hours. After hydrolysis, inactivate the enzyme in a 75°C water bath for 8 minutes to obtain the hydrolysate. Step S3, Membrane separation and purification: The enzymatic hydrolysate is centrifuged at 4℃ and 8000rpm for 30min. The supernatant is then sequentially purified by passing it through a 5000Da ultrafiltration membrane and a 1000Da nanofiltration membrane. The ultrafiltration pressure is 0.25-0.35MPa, the nanofiltration pressure is 0.5-0.6MPa, and the feed temperature is controlled at 4-8℃. The 1000Da nanofiltration permeate is collected to obtain the core active ingredient solution of white jade snail. Step S4, Steady-state compounding of active ingredients: Add compounding adjuvants to the core active ingredient solution. The compounding adjuvants are composed of glycerin, 1,3-propanediol and panthenol in a mass ratio of 5:3:2. The amount of compounding adjuvants added is 10% to 15% of the weight of the active ingredient solution. Stir and mix at low speed for 30 minutes at 25°C to obtain a targeted skin care type white snail active complex. Step S5, Aseptic filling and storage: After aseptic filtration of the complex through a 0.22μm microporous membrane, it is vacuum-filled in the dark and stored at 4–8℃.
[0007] Furthermore, in step S1, the white jade snails should be selected from adult snails with intact shells and clear crawling tracks. During the fasting and quiet recuperation period, they should be rinsed once a day with sterile water at 25°C to remove feces and impurities.
[0008] Furthermore, in step S2, the power density of the ultrasonic co-processing is 0.55 W / cm², and the enzyme is stirred once every 30 minutes during the enzymatic hydrolysis process at a stirring rate of 50 r / min for 5 minutes.
[0009] Furthermore, the 5000Da ultrafiltration membrane mentioned in step S3 is used to retain large molecular proteins, and the permeate from the 1000Da nanofiltration membrane contains snail enzyme content ≥18mg / g, glycosaminoglycan content ≥25mg / g, and growth factor content ≥12mg / mL.
[0010] Furthermore, the compounding agent mentioned in step S4 can be replaced with a mixed system of glycerol, xylitol, and vitamin B5 in a mass ratio of 4:4:2. After compounding, the stability of the active ingredients at room temperature is improved by more than 40%.
[0011] Furthermore, the process achieves a comprehensive extraction rate of ≥95.3% for the three core components: snail enzyme, glycosaminoglycan, and growth factors.
[0012] Furthermore, the total purity of the snail enzyme, glycosaminoglycan, and growth factors in the complex is ≥99.1%, the retention rate of active ingredients is ≥92.7% after 12 months of storage at room temperature, the skin fibroblast proliferation promotion rate is ≥52.6%, and there are no sensitizing impurities remaining.
[0013] Furthermore, the composite exhibits optimal stability in the pH range of 5.5–6.5 and a conductivity of 200–400 μS / cm.
[0014] Furthermore, the complex is added to serums, face creams, eye creams, and body lotions at a mass percentage of 5% to 15% for skin barrier repair, fine line reduction, and sensitive skin soothing.
[0015] Furthermore, when applied to face cream, the addition amount is 10%, and after 28 days of use, the skin barrier repair rate is ≥48.5%, and the dry lines are reduced by ≥32.7%.
[0016] The advantages of this invention compared to existing technologies are: (1) Synergistic enrichment of core components: The combination of low-temperature fractional extraction and ultrasonic synergistic enzymatic hydrolysis enables the simultaneous and efficient extraction of three types of components: snail enzyme, glycosaminoglycan, and growth factors. The comprehensive extraction rate is over 95.3%, which is much higher than the 70% to 80% of traditional processes. (2) High purity and low allergenicity: The graded membrane separation technology completely removes allergenic proteins and impurities, and the total purity of active ingredients is ≥99.1%. After skin irritation test, it has no allergic reaction to sensitive skin people, and the scope of application has been greatly expanded. (3) Excellent storage stability: The polyol compound system significantly improves the stability of active ingredients. After 12 months of storage at room temperature, the activity retention rate is ≥92.7%, which solves the industry pain point of efficacy decay of beauty products; (4) Strong compatibility with cosmetics: The compound system takes into account both efficacy and skin feel. It is non-sticky when added to cosmetic products. It can be used in a ratio of 5% to 15% to match all types of repair products such as serums, face creams, and eye creams to achieve a full-chain skin care effect of "repair-moisturize-anti-aging".
