Description

TECHNICAL FIELD

[0001] The present application belongs to the field of cosmetics, and relates to a moisturizing composition with lightening and soothing effects, a preparation method and application. BACKGROUND

[0002] Skin, as the largest organ of the human body directly contacting with the outside world, has multiple functions such as barrier, absorption, sensation, secretion and excretion, body temperature regulation, material metabolism, immunity, etc. The most basic function is the skin barrier function. When the skin barrier is damaged, not only the skin appears dry, tight, itchy, stinging, redness and other discomforts, but also severe conditions such as acne, atopic dermatitis, contact dermatitis, psoriasis, etc. may be induced, and even these conditions can further worsen the skin barrier function.

[0003] For people with oily skin and mixed skin, excessive secretion of sebum often leads to facial shine, enlarged pores and acne problems. Azelaic acid reduces the excessive secretion of sebum from the source by competitively inhibiting the enzyme process of producing dihydrotestosterone, effectively improving the problem of oily and acne skin. The reduction of sebum secretion not only controls facial shine, making the makeup more lasting, but also prevents the pores from expanding due to oil accumulation, making the skin texture more delicate. At the same time, due to the lack of "food" for propionibacteria, the formation of comedones and blackheads is also reduced accordingly, and the incidence of acne is greatly reduced, thereby helping to restore a healthy skin barrier. Skincare products are the preferred solution for repairing the skin barrier function. Moisturizers are essential in skin barrier repair because they can reduce transepidermal water loss and reduce the workload of stratum corneum cells. Bifida ferment filtrate contains various metabolic products such as polysaccharides, proteins, polypeptides, amino acids, minerals, acids, and other nutrients, and has multiple functions such as anti-oxidation, whitening, spot removal, and moisturizing. In recent years, it has been widely used as a moisturizer and skin conditioner in functional cosmetics.

[0004] For example, Chinese invention patent CN112773761B discloses a cosmetic composition, serum and preparation method thereof, which produces a synergistic effect by compounding silk protein extract, spilanthes acmella extract, biosaccharide gum-1, sodium hyaluronate, ceramide 3, lactobacillus / soybean milk fermentation product filtrate and bifida ferment filtrate, so that 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, and the composition comprises inulin, micrococcus lysate, schizosaccharomyces fermentate lysate, rice fermentate filtrate, lactobacillus / soybean milk fermentate filtrate, and water. The composition can effectively regulate skin microecological balance, and has excellent effects of removing wrinkles, preventing aging, and moisturizing and hydrating.

[0006] The above-mentioned composition or product containing schizosaccharomyces fermentate filtrate has remarkable effects in moisturizing, anti-aging, or anti-wrinkle, but lacks effects in brightening and soothing. Therefore, it is necessary to further optimize the components, compound specific functional ingredients, and optimize the ratio, so as to fundamentally improve the skin barrier and comprehensively improve the effects of moisturizing, brightening, and soothing. SUMMARY

[0007] The present application provides a composition with the effects of brightening, soothing, and moisturizing, which can repair the skin barrier by effective compounding of functional ingredients, thereby achieving the effects of brightening, soothing, and moisturizing.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] It is worth noting that the raw materials used in the present application are ordinary commercially available products, and their sources are not specifically limited.

[0029] Among them, the filtrate of Schizochytrium limulus fermentation product is purchased from Yunzhiqingshui (Tianjin) Technology Co., Ltd.

[0030] Example 1 The present embodiment provides a series of moisturizing compositions, the composition and amount of which are shown in Table 1: Table 1 Composition and amount of each moisturizing composition (unit: mass percentage %)

[0031] The preparation method is as follows: (1) Take each component of phase A, add water, heat to 85±5℃, mix uniformly, and obtain a mixed solution 1; (2) Cool to 50±5℃, add each component of phase B, mix uniformly, and obtain a mixed solution 2; (3) Continue to cool to 40±5℃, add each component of phase C, mix uniformly, finally add each component of phase D, mix uniformly, and obtain moisturizing compositions 1-8; (4) Add carbomer-940 gel to the moisturizing compositions 1-8 according to the volume-mass ratio of 1.5 mL / g, mix and stir uniformly, adjust the pH to 5.5, centrifuge at 3000 rpm for 10 min to remove bubbles, and prepare moisturizing gel masks 1-8.

[0032] Test Example 1: In vitro anti-acne efficacy test (bacteriostatic and anti-inflammatory) Dilute the activated P. acnes bacterial solution to 1×10 6 CFU / mL, add the diluted bacterial solution to a 96-well plate, 100 μL per well, add 100 μL of the above moisturizing compositions 1-8 to sample groups 1-8, add 100 μL of lactobionic acid erythromycin solution to the positive control group; add 100 μL of sterilized normal saline to the negative control group, set 3 replicates for each group; incubate the 96-well plate in an anaerobic box for 48 h, then take it out, detect the OD 600 of each well by an enzyme marker, and calculate the inhibition rate of each sample on P. acnes according to the following formula:

[0033] The results are shown in Table 2.

[0034] Table 2 Inhibition results of moisturizing compositions on P. acnes

[0035] As can be seen from the results of Table 2, the inhibition rates of the moisturizing compositions 2-4 on Propionibacterium acnes are above 85%, which are better than those of the moisturizing compositions 1 and 5, and it can be seen that the ratio of dipotassium glycyrrhizinate to azelaic acid has a significant influence on the bacteriostatic effect in the moisturizing composition of the present application, for example, in the moisturizing composition 1, when the ratio of the two exceeds a certain range, the bacteriostatic effect is even worse than that of the moisturizing composition 8 without dipotassium glycyrrhizinate and azelaic acid; in addition, the bacteriostatic effect of the moisturizing composition 6 is also greatly reduced on the basis of the moisturizing composition 3 by only replacing azelaic acid with salicylic acid with similar efficacy, and it can be seen that the combination of the specific component azelaic acid and dipotassium glycyrrhizinate effectively improves the bacteriostatic effect.

[0036] Test Example 2: Hyaluronidase Inhibition Test (Anti-sensitivity and Soothing) 0.1 mL of 0.25 mmol / L CaCl2 solution, 0.5 mL of 500 U / mL hyaluronidase solution and appropriate amount of acetic acid buffer (pH = 5.6) were taken into a conical flask, slightly shaken and mixed, incubated in a 37℃ constant temperature incubator for 20 min, then 0.5 mL of deionized water and 0.5 mL of sample liquid (moisturizing compositions 1-8) were added in turn, incubated at 37℃ for 20 min, then 0.5 mL of 0.5 mg / mL hyaluronidase potassium solution and appropriate amount of acetic acid buffer (pH = 5.6) were added, incubated at 37℃ for 40 min, then placed at room temperature for 10 min, 0.5 mL of deionized water, 1 drop of 5 mol / L NaOH solution and 1 mL of acetylacetone solution were added, heated in a boiling water bath for 15 min, immediately cooled with ice water for 5 min, placed at room temperature for 10 min, then 1 mL of P-DAB color developing agent and appropriate amount of anhydrous ethanol were added, developed at room temperature for 30 min, then the absorbance value of the sample at 530 nm was determined by using a spectrophotometer, and the inhibition rate of each group of samples on hyaluronidase was calculated, and the calculation formula is as follows:

[0037] Wherein: I is the inhibition rate of hyaluronidase; A 1 is the absorbance value of the (hyaluronidase + sample liquid + hyaluronidase potassium) solution; A 2 is the absorbance value of the (acetic acid buffer + sample liquid) solution; A 3 is the absorbance value of the (hyaluronidase + deionized water + hyaluronidase potassium) solution; A 4 is the absorbance value of the (acetic acid buffer + deionized water) solution; The results are shown in Table 3.

[0038] Table 3 Inhibition results of moisturizing compositions on hyaluronidase

[0039] From the results of Table 3, it can be seen that the inhibition effect of each moisturizing composition of the present application on hyaluronidase shows the same trend as the bacteriostatic and anti-inflammatory effects.

[0040] Test Example 3: Melanin synthesis inhibition test of moisturizing compositions (whitening) B16-F10 cells of mouse melanoma were inoculated into a 6-well plate at a density of 2 x 10 5 cells / well, and after 48 h, the plate was taken out, the medium in the well was aspirated, and washed once with PBS. The above DMEM medium containing moisturizing compositions 1-8 was added, wherein the concentration of each moisturizing composition in the medium was 50 mg / mL, and DMEM medium without any active ingredient was used as a blank control. Each well was repeated 3 times, and the culture was continued for 48 h. After the culture was completed, the cells were lysed, and the intracellular melanin was extracted by centrifugation. 200 μL of 1 mol / L sodium hydroxide solution containing 10% DMSO was added, and then placed in a water bath at 80°C for heating for 2-3 h. After the melanin was completely dissolved, 180 μL was taken into a 96-well plate, and the absorbance OD value at 492 nm was detected using an enzyme marker. The melanin inhibition rate was calculated according to the following formula:

[0041] The results are shown in Table 4.

[0042] Table 4 Inhibition results of moisturizing compositions on melanin synthesis

[0043] From the results of Table 4, it can be seen that the inhibition rate of moisturizing compositions 1-5 on melanin all reaches more than 80%, and the ratio of azelaic acid and dipotassium glycyrrhizinate has little effect on the melanin inhibition effect. On the basis of moisturizing composition 3, moisturizing composition 6 replaces azelaic acid with salicylic acid, and moisturizing composition 7 replaces dipotassium glycyrrhizinate with allantoin, and the melanin inhibitors of both have different degrees of decline. It can be seen that azelaic acid and dipotassium glycyrrhizinate can enhance the whitening effect of the filtrate of the fermentation product of Saccharomyces carnicolor.

[0044] Example 2: Investigation of auxiliary materials (1) Thickening agent: The acrylate / C10-30 alkyl acrylate crosspolymer and polyacryloyldimethyl ammonium taurate in the A phase of each acne-removing lotion raw material of Example 1 were used as thickening agents. The thickening agent was adjusted on the basis of acne-removing composition 3, as follows: Acrylates / C10-30 Alkyl Acrylate Crosspolymer 1.5% in Phase A; Acrylates / C10-30 Alkyl Acrylate Crosspolymer 1.5% in Phase A; Acrylates / C10-30 Alkyl Acrylate Crosspolymer 1.5% in Phase A;

[0045] The amounts of other components and the preparation method are the same as in Example 1.

[0046] (2) pH regulator: triethanolamine in Phase A of each acne-removing lotion in Example 1 is used as the pH regulator, and the pH regulator is adjusted based on Acne-removing lotion 3, as follows: Acne-removing composition 12: replace triethanolamine with an equal amount of citric acid; Acne-removing composition 13: replace triethanolamine with an equal amount of disodium hydrogen phosphate.

[0047] The amounts of other components and the preparation method are the same as in Example 1.

[0048] Test Example 4: Investigation of the properties and stability of the moisturizing compositions The properties (spreading property, stickiness, and stability) of moisturizing composition 3 and the moisturizing compositions 9-13 prepared in Example 2 were observed, and the results of the stability tests (whether there is layering, precipitation, and change in viscosity after being placed at (40±2) °C for 24 h, at (-10±2) °C for 24 h, and at 10,000 rpm for 30 min, respectively) are shown in Table 5.

[0049] Table 5: Test results of the properties and stability of the moisturizing compositions

[0050] As can be seen from the above table, the thickening agent and the pH regulator used in Acne-removing lotion 3 can ensure that the moisturizing composition is easy to spread, has moderate viscosity, is not sticky, and has good stability, and can withstand high and low temperatures and high-speed shaking conditions.

[0051] Test Example 5: Human efficacy test (1) Samples: Moisturizing gel masks 1-10 (among them, moisturizing gel masks 9-10 were prepared by referring to Example 1, step (4), using moisturizing compositions 9 and 10 and Carbomer-940 gel).

[0052] (2) Experimental subjects and grouping: Eighty healthy volunteers with no adverse reactions on the skin after patch testing and sensitive skin (lactic acid stinging score ≥ 3) and facial skin redness were selected as subjects for the soothing redness reduction effect evaluation; eighty healthy volunteers with no adverse reactions on the skin after patch testing and skin ITA values between 20-40 were selected as subjects for the spot lightening effect evaluation; the above subjects were randomly divided into 10 groups, namely test groups 1-10. All volunteers voluntarily participated in the test and signed a written informed consent, and promised to strictly follow the test protocol without special circumstances.

[0053] (3) Method of use and test indicators: After cleansing, the subjects rested for 15 minutes at a fixed location (ambient temperature 25±2℃, humidity 45±5%), and the red area of the face (for subjects evaluating soothing effect) or surface spots (for subjects evaluating spot lightening effect) was tested by the VISIA tester; an appropriate amount of moisturizing gel mask was evenly applied to the face, and after 10 minutes, the remaining mask was wiped off and the face was washed with running water, and the red area of the face and surface spots were tested again by the same VISIA tester, and the results are shown in Table 6.

[0054] Among them, the effect photos of the soothing redness reduction typical subjects before and after using the moisturizing gel mask 3 are shown in Figure 1 , and the red area effect before and after use is shown in Figure 2 ; for spot lightening typical subjects, the effect photos before and after using the moisturizing gel mask 3 are shown in Figure 3 , and the spot effect before and after use is shown in Figure 4 .

[0055] (4) Results: Table 6 Experimental results of red area and surface spots of subjects in each group

[0056] As can be seen from the above table, the masks containing moisturizing compositions 2-4 have the best redness reduction and soothing, spot lightening effects, followed by the masks containing moisturizing compositions 1 and 5, which shows that azelaic acid and potassium glycyrrhizinate can play a significant synergistic effect under a specific ratio. The mean change rate of red area and melanin area of the subjects further decreased when moisturizing composition 6 replaced azelaic acid in moisturizing composition 1 with salicylic acid and moisturizing composition 7 replaced potassium glycyrrhizinate in moisturizing composition 1 with allantoin; it can be seen that only specific components can achieve better redness reduction and soothing, spot lightening effects.

[0057] In addition, the type of thickening agent has certain influence on the mask effect, especially in the test group 10, the average change rate of red area and melanin area of the subjects is lower, which may be related to the larger viscosity of the mask. It can be seen that the preparation process such as the selection of adjuvant is also crucial to fully exert the efficacy of each component.

[0058] Finally, it should be noted that the above content is only used to illustrate the technical solutions of the present application, and is not a limitation on the protection scope of the present application.
