Description

Technical Field

[0001] This invention belongs to the field of cosmetics and relates to a moisturizing composition with brightening and soothing effects, its preparation method and application. Background Technology

[0002] As the largest organ in the human body that comes into direct contact with the external environment, the skin has multiple functions, including barrier function, absorption, sensation, secretion and excretion, thermoregulation, metabolism, and immunity. Among these, the most fundamental function is the skin barrier function. When the skin barrier is damaged, it not only manifests as discomfort such as dryness, tightness, itching, stinging, and redness, but in severe cases, it may also induce acne, atopic dermatitis, contact dermatitis, psoriasis, and other conditions, which can further deteriorate the skin barrier function.

[0003] For people with oily and combination skin, excessive sebum secretion often leads to facial shine, enlarged pores, and acne. Azelaic acid competitively inhibits the enzyme process that produces dihydrotestosterone, reducing excessive sebum secretion at its source and effectively improving oily and acne-prone skin. Reduced sebum secretion not only controls facial shine, making makeup last longer, but also prevents pores from enlarging due to oil buildup, resulting in smoother skin texture. Simultaneously, because Propionibacterium acnes lacks "food," the formation of blackheads and whiteheads is reduced, significantly lowering the incidence of acne and helping to restore a healthy skin barrier. Skincare products are the preferred solution for repairing the skin barrier function. Moisturizers are essential skincare products in skin barrier repair because they reduce transepidermal water loss and lessen the workload of stratum corneum cells. Bifida ferment filtrate contains a variety of metabolites, such as polysaccharides, proteins, peptides, amino acids, minerals, and acids, and has multiple effects such as anti-oxidation, whitening and spot removal, and moisturizing. In recent years, it has been widely used in functional cosmetics as a moisturizer and skin conditioner.

[0004] For example, Chinese invention patent CN112773761B discloses a cosmetic composition, essence and its preparation method. By compounding silk protein extract, purslane extract, biosaccharide gum-1, sodium hyaluronate, ceramide 3, lactobacillus / soybean milk fermentation product filtrate and bifida ferment filtrate to produce a synergistic effect, the cosmetic composition has good moisturizing, anti-wrinkle and skin damage repair effects.

[0005] For example, Chinese invention patent CN118161425B discloses a composition containing bio-fermentation products for regulating skin microecology and its application. The composition includes inulin, micrococcal lysate, bifida ferment lysate, rice fermentation product filtrate, lactobacillus / soybean milk fermentation product filtrate, and water. This composition can effectively adjust the skin microecological balance and has excellent effects in removing wrinkles, preventing aging, and moisturizing.

[0006] The above-mentioned compositions or products containing Bifida Ferment Lysate filtrate are effective in moisturizing, anti-aging, or anti-wrinkle, but lack the effect in brightening and soothing. Therefore, it is necessary to further optimize its components and fundamentally improve the skin barrier through the compounding and ratio optimization of specific functional ingredients to achieve a comprehensive improvement in moisturizing, brightening, and soothing effects.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] It is worth noting that the raw materials used in this invention are all commercially available products, and their sources are not specifically limited.

[0039] The Bifida ferment filtrate was purchased from Yunzhiqingshui (Tianjin) Technology Co., Ltd.

[0040] Example 1

[0041] This embodiment provides a series of moisturizing compositions, the composition and dosage of which are shown in Table 1:

[0042] Table 1. Composition and dosage of each moisturizing composition (unit: mass percentage %)

[0043]

[0044] The preparation method is as follows:

[0045] (1) Take each component of phase A and add it to water, heat it to 85±5℃ and mix it evenly to obtain mixture 1;

[0046] (2) Cool down to 50±5℃, add each component of phase B and mix evenly to obtain mixture 2;

[0047] (3) Continue to cool down to 40±5℃, add the components of phase C and mix evenly, and finally add the components of phase D and mix evenly to obtain moisturizing composition 1-8.

[0048] (4) Add moisturizing composition 1-8 to carbomer-940 gel at a volume-to-mass ratio of 1.5 mL / g and mix well. Adjust the pH to 5.5 and centrifuge at 3000 rpm for 10 min to remove air bubbles to obtain moisturizing gel mask 1-8.

[0049] Test Example 1: External Acne Treatment Efficacy Test (Antibacterial and Anti-inflammatory)

[0050] Dilute the activated Propionibacterium acnes bacterial solution to 1×10⁻⁶. 6 CFU / mL, the diluted bacterial culture was added to 96-well plates, 100 μL per well. Sample groups 1-8 were each added to 100 μL of the above-mentioned moisturizing composition 1-8. The positive control group was added to 100 μL of lactobionic acid erythromycin solution. The negative control group was added to 100 μL of sterile physiological saline. Each group was set up with 3 replicates. The 96-well plates were incubated in an anaerobic incubator for 48 h. After that, the OD of each well was detected by a microplate reader. 600 The inhibition rate of each group of samples against Propionibacterium acnes was calculated using the following formula:

[0051]

[0052] The results are shown in Table 2.

[0053] Table 2. Inhibition results of the moisturizing composition on Propionibacterium acnes

[0054]

[0055] As can be seen from the results in Table 2, the inhibition rate of moisturizing compositions 2-4 against Propionibacterium acnes is above 85%, which is better than that of moisturizing compositions 1 and 5. It can be seen that in the moisturizing compositions of the present invention, the ratio of dipotassium glycyrrhizate to azelaic acid has a significant impact on the antibacterial effect. For example, when the ratio of the two exceeds a certain range, the antibacterial effect of moisturizing composition 1 is even worse than that of moisturizing composition 8, which does not contain dipotassium glycyrrhizate and azelaic acid. In addition, the antibacterial effect of moisturizing composition 6, which is based on moisturizing composition 3 but only replaces azelaic acid with salicylic acid with similar effects, is also greatly reduced. It can be seen that the combination of azelaic acid and dipotassium glycyrrhizate, specific components of the present invention, effectively improves the antibacterial effect.

[0056] Test Example 2: Hyaluronidase Inhibition Test of Moisturizing Composition (Anti-allergic and Soothing)

[0057] Transfer 0.1 mL of 0.25 mmol / L CaCl2 solution, 0.5 mL of 500 U / mL hyaluronidase solution, and an appropriate amount of acetate buffer (pH=5.6) into an Erlenmeyer flask, gently shake to mix, and incubate at 37°C for 20 min. Then add 0.5 mL of deionized water and 0.5 mL of sample solution (representing moisturizing compositions 1-8), and incubate at 37°C for 20 min. Next, add 0.5 mL of 0.5 mg / mL potassium hyaluronidase solution and an appropriate amount of acetate buffer (pH=5.6), and incubate at 37°C for 40 min. Then, place at room temperature for 10 min. Add 0.5 mL of deionized water, 1 drop of 5 mol / L NaOH solution, and 1 mL of acetylacetone solution. Heat in a boiling water bath for 15 min, immediately cool with ice water for 5 min, place at room temperature for 10 min, and then add 1 mL of... P-DAB chromogenic reagent was mixed with an appropriate amount of anhydrous ethanol and allowed to stand at room temperature for 30 minutes for color development. Then, the absorbance of the sample at 530 nm was measured using a spectrophotometer, and the inhibition rate of hyaluronidase for each group of samples was calculated using the following formula:

[0058]

[0059] in: I Hyaluronidase inhibition rate;

[0060] A 1 represents the absorbance value of the (hyaluronidase + sample solution + potassium hyaluronidase) solution;

[0061] A 2 represents the absorbance value of the (acetic acid buffer + sample solution);

[0062] A 3 represents the absorbance value of the solution (hyaluronidase + deionized water + potassium hyaluronidase);

[0063] A 4 represents the absorbance value of the (acetic acid buffer + deionized water) solution;

[0064] The results are shown in Table 3.

[0065] Table 3. Inhibition results of the moisturizing composition on hyaluronidase

[0066]

[0067] As can be seen from the results in Table 3, the various moisturizing compositions of the present invention exhibit the same trend in their inhibitory effect on hyaluronidase and their antibacterial and anti-inflammatory effects.

[0068] Test Example 3: Melanin Synthesis Inhibition Test of Moisturizing Composition (Brightening and Yellowing Removal)

[0069] Mouse melanoma cells B16-F10 were used at a rate of 2×10⁻⁶. 5 Cells were seeded at a density of 100 cells / well into 6-well plates. After 48 hours, the plates were removed, the culture medium in the wells was discarded, and the cells were washed once with PBS. DMEM medium containing moisturizing compositions 1-8 (50 mg / mL) was added to each well. DMEM medium without any active ingredients was used as a blank control. Each well was cultured in triplicate for another 48 hours. After culture, cells were lysed, centrifuged, and intracellular melanin was extracted. 200 μL of a 1 mol / L sodium hydroxide solution containing 10% DMSO was added, and the plate was then heated in an 80°C water bath for 2-3 hours. After the melanin was completely dissolved, 180 μL was transferred to a 96-well plate, and the absorbance (OD) at 492 nm was measured using a microplate reader. The melanin inhibition rate was calculated using the following formula:

[0070]

[0071] The results are shown in Table 4.

[0072] Table 4. Results of the moisturizing composition on the inhibition of melanin synthesis

[0073]

[0074] As can be seen from the results in Table 4, the melanin inhibition rate of moisturizing compositions 1-5 all reached over 80%, indicating that the ratio of azelaic acid to dipotassium glycyrrhizate has little effect on the melanin inhibition effect. Based on moisturizing composition 3, moisturizing composition 6 replaced azelaic acid with salicylic acid, and moisturizing composition 7 replaced dipotassium glycyrrhizate with allantoin. The melanin inhibition rate of these compositions decreased to varying degrees, indicating that azelaic acid and dipotassium glycyrrhizate can enhance the whitening effect of Bifida ferment lysate.

[0075] Example 2: Investigation of excipients

[0076] (1) Thickener: In Example 1, the acrylic (ester) / C10-30 alkanol acrylate crosspolymer and polyacrylamide dimethyl taurate ammonium in phase A of the raw materials of each acne lotion were used as thickeners. The thickeners were adjusted based on the acne composition 3 as follows:

[0077] Acne-removing composition 9: Phase A contains only 1.5% acrylic (ester) / C10-30 alkanol acrylate crosspolymer as thickener;

[0078] Acne-removing composition 10: The thickener in phase A is only 1.5% ammonium polyacrylamide dimethyl taurate;

[0079] Acne-removing composition 11: Acrylic (ester)-based / C10-30 alkanol acrylate crosspolymer and polyacrylamide dimethyl taurate ammonium are used as phase B components, and gum arabic is used as phase A component, with the amounts remaining unchanged.

[0080] The dosage of other components and the preparation method are the same as in Example 1.

[0081] (2) pH adjuster: Triethanolamine in phase A of the raw materials of each acne lotion in Example 1 was used as a pH adjuster. The pH adjuster was adjusted based on acne lotion 3 as follows:

[0082] Acne treatment composition 12: triethanolamine is replaced with an equal amount of citric acid;

[0083] Acne treatment composition 13: replace triethanolamine with an equal amount of disodium hydrogen phosphate.

[0084] The dosage of other components and the preparation method are the same as in Example 1.

[0085] Test Example 4: Study on the Properties and Stability of Moisturizing Compositions

[0086] The properties (spreadability, viscosity and stability) of moisturizing composition 3 and moisturizing compositions 9-13 prepared in Example 2 were observed and tested. The stability was examined by observing whether the composition separated into layers, precipitated and the viscosity changed after being placed at (40±2)℃ for 24h, at -(10±2)℃ for 24h and centrifuged at 10000rpm for 30min. The results are shown in Table 5.

[0087] Table 5. Results of tests on the properties and stability of the moisturizing composition.

[0088]

[0089] As can be seen from the table above, the thickener and pH adjuster used in the acne-removing lotion 3 of the present invention can ensure that the moisturizing composition is easy to spread and has a moderate viscosity between 400,000 and 600,000 mPa·s. It is non-sticky and has good stability, and can withstand high and low temperatures as well as high-speed vibration.

[0090] Test Example 5: Human Efficacy Trial

[0091] (1) Sample:

[0092] Moisturizing gel masks 1-10 (wherein, moisturizing gel masks 9-10 are prepared by moisturizing compositions 9 and 10 and carbomer-940 gel according to step (4) of Example 1).

[0093] (2) Experimental subjects and grouping:

[0094] Eighty healthy volunteers with sensitive skin (lactic acid stinging score ≥3) and facial redness who showed no adverse skin reaction after patch testing were selected as subjects for evaluating the soothing and redness-reducing effect; another 80 healthy volunteers with skin ITA values ​​between 20 and 40 who showed no adverse skin reaction after patch testing were selected as subjects for evaluating the spot-fading and brightening effect. All subjects were randomly divided into 10 groups, designated as Trial Groups 1-10. All volunteers voluntarily participated in the trial, signed written informed consent forms, and pledged to strictly adhere to the trial protocol unless special circumstances arise.

[0095] (3) Usage method and test indicators:

[0096] After cleansing, all subjects rested for 15 minutes in a fixed location (ambient temperature 25±2℃, humidity 45±5%). Staff used the VISIA testing instrument to test the red areas (for subjects evaluating the soothing effect) or surface spots (for subjects evaluating the brightening effect). An appropriate amount of moisturizing gel mask was applied evenly to the subject's face, left on for 10 minutes, and then the remaining mask was wiped off and the face was washed with running water. The same staff used the same VISIA testing instrument to test the red areas and surface spots on the subject's face. The results are shown in Table 6.

[0097] Among them, the before and after photos of typical subjects using the moisturizing gel mask to soothe redness are shown below. Figure 1 See the red area before and after use for the effect. Figure 2 For typical subjects who used the moisturizing gel mask to lighten dark spots and brighten their complexion, see the before and after photos. Figure 3 See before and after photos for spot effects. Figure 4 .

[0098] (4) Results:

[0099] Table 6. Results of the experiment on the red area and surface spots on the faces of subjects in each group.

[0100]

[0101] As shown in the table above, masks containing moisturizing compositions 2-4 have the best effects in reducing redness, soothing, and brightening skin, followed by masks containing moisturizing compositions 1 and 5. This indicates that azelaic acid and dipotassium glycyrrhizate in the compositions can exert a significant synergistic effect under specific ratios. Furthermore, when moisturizing composition 6 replaces azelaic acid in moisturizing composition 1 with salicylic acid, and moisturizing composition 7 replaces dipotassium glycyrrhizate in moisturizing composition 1 with allantoin, the mean change rates of redness area and melanin area in the subjects further decrease. This demonstrates that only a specific combination of components can achieve better effects in reducing redness, soothing, and brightening skin.

[0102] In addition, the type of thickener has a certain impact on the effect of the mask. In particular, in the 10 experimental groups, the average change rate of the red area and melanin area of ​​the subjects was relatively low. This may be related to the high viscosity of the mask. It can be seen that in order to make the efficacy of each component fully exerted, the preparation process, such as the selection of excipients, is also crucial.

[0103] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
