Description

Technical Field

[0001] This invention belongs to the field of cosmetic raw material compounding, specifically, it relates to a composition containing prickly pear fruit extract and its preparation method. Background Technology

[0002] On the one hand, ROS directly oxidizes lipids, proteins, and DNA, damaging the stratum corneum barrier and accelerating collagen fiber degradation; on the other hand, it activates signaling pathways such as NF-κB and AP-1, prompting the release of large amounts of pro-inflammatory mediators such as IL-1β, TNF-α, and COX-2, which manifest as skin stinging, erythema, dryness, itching, and desquamation, and may even induce chronic problems such as sensitivity, acne, and rosacea.

[0003] Currently, most commercially available antioxidant and soothing cosmetics use single or simply layered active ingredients: 1. They rely solely on purely chemical antioxidants such as vitamin C, vitamin E, and coenzyme Q10, which have drawbacks such as poor stability, strong irritation, and easy oxidation and inactivation; 2. They use single soothing agents such as dipotassium glycyrrhizate and bisabolol, which can suppress inflammation in the short term, but are insufficient in their ability to scavenge ROS and cannot break the vicious cycle of "oxidation-inflammation"; 3. Some formulas, in order to balance moisturizing and repair, blindly increase the content of matrix ingredients such as hyaluronic acid and ceramides, resulting in a heavy and sticky texture, and failing to synergistically amplify the antioxidant-soothing effects.

[0004] In addition, traditional extraction processes often use high temperatures and strong acids / alkalis, which can easily damage the active structure and produce irritating residues, making it difficult to simultaneously meet the multiple requirements of safety, gentleness, and high efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a composite active composition that has the advantages of high antioxidant efficiency, rapid soothing, mild and non-irritating properties, and green and environmentally friendly preparation process.

[0006] To achieve the above objectives, the present invention discloses the following technical solutions:

[0007] In a first aspect, the present invention provides a composition containing prickly pear fruit extract, wherein, by weight parts, the composition comprises the following:

[0008]

[0009]

[0010] Preferably, the preparation method of the prickly pear fruit extract includes the following steps:

[0011] Step 1-1. Take a certain amount of dried prickly pear fruit, crush it, and sieve it to obtain dried prickly pear fruit powder;

[0012] Steps 1-2. Mix the dried prickly pear fruit powder with petroleum ether and then reflux to extract the powder. Discard the liquid and keep the residue. Dry the residue to obtain defatted fruit powder.

[0013] Steps 1-3. Mix defatted fruit powder with deionized water, heat and extract, centrifuge to collect the supernatant after extraction, concentrate the supernatant under reduced pressure to obtain crude extract;

[0014] Steps 1-4. After mixing the crude extract with anhydrous ethanol, let it stand for 20-24 hours, collect the precipitate, and dry the precipitate to obtain the prickly pear fruit extract.

[0015] More preferably, in step 1-1, the dried prickly pear fruit is crushed and then passed through a 60-mesh sieve.

[0016] More preferably, in steps 1-2, the dried prickly pear fruit powder and petroleum ether are mixed in a reflux extraction device at a mass-to-volume ratio of 1:10-15 g / mL, and refluxed at 60-70℃ for 3 times, each time for 0.8-1 h. The filtrate is discarded and the residue is retained. The residue is dried at 40-50℃ to constant weight to obtain defatted fruit powder.

[0017] More preferably, in steps 1-3, defatted fruit powder and deionized water are mixed at a mass-to-volume ratio of 1:25-30 g / mL, and extracted by water bath heating at 60°C for 12-16 h. After extraction, the supernatant is collected by centrifugation, and the supernatant is concentrated under reduced pressure to 1 / 6 of its original volume to obtain crude extract.

[0018] More preferably, in steps 1-4, after cooling the crude extract to 30-35°C, anhydrous ethanol is added until the final ethanol concentration in the system is 70-80 v / v%. The mixture is then allowed to stand at 30-35°C for 20-24 hours, the precipitate is collected, and the precipitate is dried at 40-50°C for 1-2 hours. Finally, it is freeze-dried at -40 to -30°C for 36-40 hours to obtain the prickly pear fruit extract.

[0019] Preferably, the method for preparing the olive leaf extract includes the following steps:

[0020] Step 2-1. Take dried olive leaves, crush them through a 60-mesh sieve to obtain olive leaf powder;

[0021] Step 2-2. Mix olive leaf powder with 60-70 v / v% ethanol aqueous solution at a mass-volume ratio of 1:20-25 g / mL, and extract with ultrasonic assistance at 25-28 kHz for 35-45 min. After ultrasonic extraction, centrifuge at 5000-6000 r / min for 10 min. Concentrate the supernatant under reduced pressure at a temperature of 50-60℃ until it is reduced to 1 / 10 of its original volume to obtain olive leaf extract.

[0022] In a second aspect, the present invention provides the use of the composition described in the first aspect in the preparation of skin care products having antioxidant, anti-aging, whitening and / or soothing effects.

[0023] Thirdly, the present invention provides an antioxidant and soothing essence lotion, wherein the essence lotion contains the composition described in the first aspect, as well as a moisturizer, an antioxidant, an emulsifier, a preservative, a thickener, a plant oil, a synthetic oil, a pH adjuster, and water.

[0024] Preferably, the composition is added to the serum in an amount of 10-15 wt%.

[0025] Fourthly, the present invention provides a method for preparing the essence lotion described in the third aspect, the method comprising the following steps:

[0026] The essence emulsion is obtained by mixing the aforementioned composition, moisturizer, antioxidant, emulsifier, preservative, thickener, vegetable oil, synthetic oil, pH adjuster and water evenly.

[0027] In this invention:

[0028] The prickly pear fruit extract obtained by ethanol precipitation process is combined with tremella polysaccharide to form a complex polysaccharide system, which enhances the free radical scavenging ability. The introduction of olive leaf extract and centella asiatica extract into the complex polysaccharide system enhances the antioxidant and soothing properties of the system.

[0029] The olive leaf extract obtained by ultrasound-assisted ethanol extraction retains and enriches active ingredients such as oleuropein, hydroxytyrosol, flavonoids, etc., which can synergistically inhibit the release of inflammatory mediators and enhance the soothing effect with other components in the system.

[0030] Centella asiatica extract is rich in active ingredients such as triterpenoid saponins, including asiaticoside, hydroxyasiaticoside, asiatic acid, and hydroxyasiatic acid. It has active effects such as stimulating collagen synthesis, accelerating barrier repair, anti-inflammatory and soothing, relieving sensitivity, and scavenging free radicals. It can synergistically inhibit the release of inflammatory mediators with other components in the system, enhance the soothing effect, synergistically promote antioxidant effects, and enhance the protection against oxidative damage.

[0031] Tremella polysaccharide is a plant-derived acidic heteropolysaccharide. Its high content of hydroxyl and carboxyl groups can form a three-dimensional hydration network in the stratum corneum, effectively increasing skin moisture content and reducing transepidermal water loss. It can also activate the stratum corneum, accelerate stratum corneum renewal, repair barrier damage, reduce the level of inflammatory factors, soothe sensitivity, and reduce inflammatory reactions.

[0032] The beneficial effects of this invention are:

[0033] 1. This invention achieves a synergistic enhancement of antioxidant and soothing effects through a scientific ratio of prickly pear fruit extract, olive leaf extract, centella asiatica extract and tremella polysaccharide, covering multiple skin care needs such as anti-aging and whitening, and overcoming the limitations of single-ingredient efficacy.

[0034] 2. Experiments of this invention show that the absence of any one of the components of prickly pear fruit extract, olive leaf extract, centella asiatica extract, and tremella polysaccharide leads to a significant decrease in the activity of the system, proving that there is a certain synergistic mechanism among the four components, ensuring that the formula has better efficacy in skin care products.

[0071] Deionized water was used instead of ABTS solution as the background group, and the rest was the same as the test group.

[0072] 1,3-hydroxyl radical scavenging

[0073] Test solutions: the efficacy solutions 1-8 prepared above;

[0074] The method was modified based on the reference "Effects of Different Fertilization Patterns on Total Polyphenol Content and Antioxidant Activity of Camellia oleifera Cake in Vietnam". 1 mL of the test solution and 1 mL of 9 mmol·L⁻¹ solution were used. -1 FeSO4·7H2O, 1 mL 9 mmol·L -1 Salicylic acid, 1 mL 9 mmol·L -1 Based on H2O2, deionized water was added to a total volume of 10 mL as the test group. After incubation at 37℃ for 10 min, the absorbance at 510 nm was measured.

[0083] T 空白 The absorbance is represented by deionized water instead of the sample.

[0084] The results are shown in Table 3.

[0085] Table 3. Antioxidant Test Results

[0086] Group DPPH free radical scavenging rate / % ABTS free radical scavenging rate / % Hydroxyl radical scavenging rate / % Positive control group 95.3 99.8 12.51 Efficacy Solution 1 94.2 93.1 72.0 Efficacy Solution 2 96.0 94.8 73.1 Efficacy Solution 3 96.8 94.0 72.4 Efficacy Solution 4 95.7 95.0 71.8 Efficacy Solution 5 84.0 82.1 45.5 Efficacy Solution 6 80.2 81.3 52.8 Efficacy Solution 7 88.0 85.2 63.7 Efficacy Solution 8 90.1 91.2 66.8

[0087] Results analysis:

[0088] According to the experimental results, the DPPH scavenging rate and ABTS scavenging rate of efficacy solutions 1-4 are close to or exceed those of the positive control VC, while the hydroxyl radical scavenging rate is significantly better than that of the positive control. This proves that the combination of prickly pear fruit extract, olive leaf extract, centella asiatica extract and tremella polysaccharide has outstanding advantages in combating key free radicals of oxidative damage and can effectively scavenge free radicals to achieve anti-aging effects. Among them, efficacy solution 3 has the best overall performance.

[0089] Efficacy solutions 5-7 are based on the formulation of efficacy solution 3, but with the key components missing, resulting in a decrease in the antioxidant properties of efficacy solutions 5-7. The prickly pear fruit extract provided by this invention contains abundant prickly pear polysaccharides, which have excellent antioxidant effects. This experiment verified that adding olive leaf extract, centella asiatica extract and tremella polysaccharide to the prickly pear polysaccharide system can effectively promote the antioxidant effect of the system, and the combination has outstanding effects.

[0090] The mass ratio of prickly pear fruit extract to tremella polysaccharide in efficacy solution 8 was adjusted, resulting in a less effective antioxidant effect than efficacy solution 3. This indicates that the polysaccharide system formed by prickly pear fruit extract and tremella polysaccharide follows a certain mass ratio.

[0091] 2. Soothing Efficacy Test - Hyaluronidase Inhibition Rate

[0092] 2.1 Experimental Objective: Hyaluronidase is a specific lysing enzyme of hyaluronic acid and a participant in allergic reactions, strongly correlated with histamine release from mast cells. The soothing effect of the test sample can be determined using the hyaluronidase inhibition rate; a higher inhibition rate indicates a stronger soothing effect, and vice versa.

[0093] 2.2 Test solution and control

[0094] Test solution: efficacy solution 1-8; positive control: 1% dipotassium glycyrrhizate aqueous solution; negative control: deionized water.

[0095] 2.3 Experimental Procedure: 500 U / mL hyaluronidase solution; pH 5.4 acetate buffer; 0.5 mg / mL sodium hyaluronate solution;

[0096] Follow the steps below:

[0097]

[0098] Note: The sample solution is either efficacy solution 1-8 or a positive or negative control.

[0103] 2.5 Data Analysis

[0104] The statistical analysis software used was SPSS 19.0. The independent samples t-test was used for comparisons between groups. All statistical analyses were two-tailed tests, and the significance level was α = 0.05. P > 0.05 indicated that there was no significant difference between the two groups, and p < 0.05 indicated that there was a significant difference between the two groups.

[0108] Note: In the table, "a" indicates a significant difference compared with the negative control group, P < 0.05; "b" indicates a significant difference between the efficacy solution groups 5-8 and the efficacy solution group 3, P < 0.05.

[0109] 2.7 Results Analysis

[0110] As shown in Table 4, the hyaluronidase inhibition rate of solutions 1-4 was significantly higher than that of the negative control group (P < 0.05), and the inhibition rate was close to 76.41% of that of the positive control group. This indicates that the composition provided by the present invention has excellent soothing efficacy and can effectively promote skin barrier repair.

[0111] The hyaluronidase inhibition rate of efficacy solution 3 was significantly higher than that of efficacy solutions 5-8 (P<0.05), indicating that in the complex polysaccharide system formed by prickly pear fruit extract and tremella polysaccharide, olive leaf extract and centella asiatica extract can effectively exert their antioxidant and soothing repair effects. The absence of one of the components will have a certain impact on the performance of the system. Moreover, in this polysaccharide system, prickly pear fruit extract and tremella polysaccharide can achieve better efficacy only when they are in a certain mass ratio.
