Description

Technical Field

[0001] The present application relates to the technical field of cosmetics, and in particular to a composition for preparing cosmetics, a preparation method thereof, and the cosmetics. Background Art

[0002] Chia seeds, derived from the seeds of Salvia Hispania L., belong to the Lamiaceae family and are certified safe by the US FDA. In recent years, chia seeds have demonstrated remarkable antioxidant, lipid-lowering, and cardiovascular health benefits. Their excellent biological properties have attracted increasing attention as a potential source of cosmetic raw materials. However, currently, chia seed-based cosmetic raw materials lack the ability to combine whitening, antioxidant, antibacterial, hydration, and moisturizing properties, limiting their application in cosmetics.

[0003] At present, the extraction processes for extracting active ingredients from natural substances generally include water extraction and alcohol precipitation, organic solvent extraction, and ultrasonic extraction. However, the above processes either require the use of organic solvents or require drastic reaction conditions (for example, high ultrasonic power, etc.); the use of organic solvents can easily lead to the presence of organic solvent residues in the extracted active ingredients, which is not conducive to fully exerting the effects of the active ingredients; drastic reaction conditions can easily destroy the structure of the active ingredients, which is not conducive to fully exerting the effects of the active ingredients, and may even cause the active ingredients to be unable to function. Therefore, it is necessary to develop an extraction process that can solve the problem of organic solvent residues (i.e., green and environmentally friendly) and can fully retain the structure of the active ingredients.

[0052] As an example, the culture is continued for 6 days, 7 days, 8 days, 9 days, 10 days, and so on.

[0053] Furthermore, continuing the culture for 7-9 days can further increase the content of active ingredients such as protein, polysaccharide and total polyphenols in the composition, which is beneficial to further improve the whitening (tyrosinase inhibition rate can reach more than 55%), antioxidant (DPPH free radical scavenging rate can reach more than 80%), antibacterial, hydration and moisturizing effects.

[0054] In the present application, the temperature for continued cultivation is 25-30° C., which is conducive to promoting the stable and continuous secretion of active ingredients from the root system of the chia seed germinated body. As an example, the temperature for continued cultivation can be 25° C., 27° C., 28° C. or 30° C., etc.

[0055] In the present application, the step of keeping the roots of the chia seed sprouts submerged in water includes: spraying water on the chia seed sprouts at a flow rate of 30-60 mL / min, so that the secretions at the roots of the chia seed sprouts can be fully washed into the water system in which the roots of the chia seed sprouts are immersed in the continued cultivation environment, and the content of active ingredients such as protein, polysaccharides and total polyphenols in the composition can be further increased, which is beneficial to further improve the whitening, antioxidant, antibacterial, hydration and moisturizing effects.

[0074] This comparative example provides a method for preparing a composition for preparing cosmetics. The difference between this comparative example and Example 1 is that the culturing time is continued for 4 days.

[0075] Experimental Example 1

[0076] The contents of protein, polysaccharide and total polyphenols in the compositions prepared in Examples 1-3 and Comparative Examples 1-2 were measured, and the measurement results are shown in Table 1.

[0077] Among them, the protein content was determined using the BCA protein quantification kit; the detection principle is: under alkaline conditions, the protein converts Cu 2+ Reduction to Cu + , Cu + It forms a purple complex with BCA reagent. Two BCA molecules chelate one Cu + A water-soluble complex is formed, which absorbs at 562 nm.

[0078] The measurement steps are as follows:

[0079] (1) Forming a standard curve:

[0080] Dissolve bovine serum albumin in distilled water and prepare standard curve solutions of 0 mg / mL, 0.025 mg / mL, 0.05 mg / mL, 0.1 mg / mL, 0.2 mg / mL, and 0.3 mg / mL, respectively. Pipette 200 μL of the standard curve solutions of different concentrations into different enzyme-labeled wells, and add 200 μL of BCA reagent to the enzyme-labeled wells containing the standard curve solutions of different concentrations. After gently shaking, keep the mixture at 37°C for 60 min, cool to room temperature, and use a blank as a control. Perform colorimetry at 562 nm on a microplate reader. Draw a standard curve with the mass concentration of bovine serum albumin in the standard curve solution as the abscissa and the absorbance at 562 nm as the ordinate.

[0081] (2) Detecting the protein content in the test composition:

[0082] 200 μL of the compositions prepared in Examples 1-3 and Comparative Examples 1-2 were respectively pipetted into different enzyme-labeled wells, and 200 μL of BCA reagent was added to the enzyme-labeled wells containing the compositions prepared in Examples 1-3 and Comparative Examples 1-2. After gentle shaking, the mixture was incubated at 37° C. for 60 min. After cooling to room temperature, the mixture was detected on a microplate reader, and the protein content was calculated from the standard curve based on the absorbance value of the test sample at 562 nm.

[0083] The polysaccharide content was determined using the phenol-sulfuric acid method; the detection principle is: polysaccharides are first hydrolyzed into monosaccharides under the action of sulfuric acid, and rapidly dehydrated to form aldehyde derivatives, which then react with phenol to form an orange-yellow compound that absorbs at 490nm.

[0084] The measurement steps are as follows:

[0085] (1) Forming a standard curve:

[0086] Dissolve glucose in distilled water, accurately weigh 10 mg of dry constant weight glucose, and distilled water to 10 mL to prepare a 1 mg / mL glucose solution. Pipette 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5 mL of the prepared glucose solution, respectively, and make up to 1 mL with distilled water. Then, add 1 mL of 5% phenol aqueous solution and 5 mL of concentrated sulfuric acid, respectively. Shake well and cool. After standing at room temperature for 20 minutes, obtain standard curve solutions of different concentrations. Use distilled water as a blank control, measure the absorbance at 490 nm, and draw a standard curve with the concentration of glucose solution as the horizontal axis and the absorbance value at 490 nm as the vertical axis.

[0087] (2) Detecting the content of polysaccharides in the test composition:

[0088] 1.0 mL of the composition prepared in Examples 1-3 and Comparative Examples 1-2 was respectively taken, and then 1 mL of a 5% mass fraction phenol aqueous solution and 5 mL of concentrated sulfuric acid were added, respectively. The mixture was shaken and cooled, and then placed at room temperature for 20 minutes to obtain a sample to be loaded on the machine. The polysaccharide content was calculated from the standard curve according to the absorbance value of the sample to be tested at 490 nm.

[0089] The total polyphenol content was determined using the Folin-ciocalteu reagent. The detection principle is that the tungstomolybdic acid in the Folin-ciocalteu reagent can quantitatively oxidize the polyphenol compounds and itself is reduced to form a blue compound. The absorbance of the blue compound at 760 nm is positively correlated with the polyphenol content.

[0090] The measurement steps are as follows:

[0091] (1) Forming a standard curve:

[0092] Pyrogallol was dissolved in distilled water to prepare 2 μg / mL, 4 μg / mL, 6 μg / mL, 8 μg / mL, and 10 μg / mL pyrogallol solutions to obtain standard curve solutions of different concentrations. 1.0 mL of the standard curve solutions of different concentrations was pipetted into different 100 mL volumetric flasks, 60 mL of water was added to each volumetric flask and mixed, and then 5 mL of FoLin-CiocaLteu reagent was added to each volumetric flask and mixed. Then, 15 mL of a 20% sodium carbonate aqueous solution was added to each volumetric flask within 8 minutes, and the volume was adjusted to 100 mL with water. After standing at 20°C for 2 hours, 100 μL of the solutions from different volumetric flasks were respectively pipetted into different enzyme-labeled wells. The blank was used as a control, and the colorimetry was performed at 760 nm on a microplate reader. The standard curve was plotted with the concentration of the pyrogallol solution as the horizontal axis and the absorbance value at 760 nm as the vertical axis.

[0093] (2) Detecting the content of total polyphenols in the test composition:

[0094] 1.0 mL of the composition prepared in Examples 1-3 and Comparative Examples 1-2 was respectively drawn into different 100 mL volumetric flasks, 60 mL of water was added to each volumetric flask and mixed, and then 5 mL of FoLin-CiocaLteu reagent was added to each volumetric flask and mixed. Then, 15 mL of a 20% sodium carbonate aqueous solution was added to each volumetric flask within 8 minutes, and the volume was made up to 100 mL with water. After standing at 20° C. for 2 hours, samples to be loaded were obtained, 100 μL of the samples to be loaded were respectively drawn into different enzyme-labeled wells, and the samples were detected on a microplate reader. The total polyphenol content was calculated from the standard curve according to the absorbance value of the sample to be tested at 760 nm.

[0095] Table 1

[0096]

[0097] As can be seen from Table 1, the contents of protein, polysaccharide and total polyphenols in the compositions prepared in Examples 1-3 are significantly higher than those in the compositions prepared in Comparative Examples 1-2, indicating that continuing the culture for 6-10 days can effectively increase the contents of protein, polysaccharide and total polyphenols in the compositions.

[0098] Furthermore, from the comparison of Examples 1-3, it can be seen that when the culture time is continued for 8 days, the contents of protein, polysaccharide and total polyphenols in the prepared composition reach the highest.

[0099] Experimental Example 2

[0100] The DPPH radical scavenging ability of the compositions prepared in Examples 1-3 and Comparative Examples 1-2 was tested, and the test results were as follows: Figure 2 As shown. The test method for free radical scavenging ability is as follows: 2 mL of the composition and 2 mL of 0.2 mM DPPH solution are placed in the same test tube, mixed using a vortex mixer, reacted in the dark for 30 minutes, and the absorbance Ai at 517 nm is measured using a UV spectrophotometer. At the same time, the absorbance Aj at 517 nm of 2 mL of the composition and 2 mL of 95% ethanol by volume is measured, and the absorbance Ac at 517 nm of 2 mL of 95% ethanol by volume is measured. The calculation formula for DPPH free radical scavenging rate is as follows:

[0101]

[0102] from Figure 2It can be seen that the DPPH radical scavenging ability of the compositions prepared in Examples 1-3 is significantly higher than that of the compositions prepared in Comparative Examples 1-2, indicating that continuing the culture for 6-10 days can effectively improve the DPPH radical scavenging ability (i.e., antioxidant capacity).

[0103] Furthermore, from the comparison of Examples 1-3, it can be seen that when the culture time is continued for 8 days, the DPPH free radical scavenging ability of the prepared composition reaches the highest.

[0115] Sample C0: Take 1.5 mL of the prepared phosphate buffer and incubate in a 37°C water bath for 10 min. Then add 2 mL of the prepared levodopa solution and react for 5 min to obtain sample C0.

[0116] (3) Using 0.2 mg / mL kojic acid as a positive control, the absorbance of the T sample, T0 sample, C sample, and C0 sample at 475 nm was measured, and the absorbances were recorded as T, T0, C, and C0, respectively. The tyrosinase inhibition rate was calculated as follows:

[0117]

[0118] from Figure 3 It can be seen that the tyrosinase inhibitory ability of the compositions prepared in Examples 1-3 is significantly higher than that of the compositions prepared in Comparative Examples 1-2, indicating that continuing the culture for 6-10 days can effectively improve the tyrosinase inhibitory ability (i.e., whitening effect).

[0119] Furthermore, from the comparison of Examples 1-3, it can be seen that when the culture time is continued for 8 days, the tyrosinase inhibition ability of the prepared composition reaches the highest.

[0120] Experimental Example 4

[0121] The antibacterial ability of the compositions prepared in Examples 1-3 and Comparative Examples 1-2 was tested, and the antibacterial ability of the compositions against Escherichia coli (ATCC8739), Staphylococcus aureus (ATCC6538), and Pseudomonas aeruginosa (ATCC9027) was tested, respectively. The test results are shown in Table 2.

[0122] The antibacterial ability test adopts the inhibition zone method, and the specific steps are as follows:

[0123] (1) Preparation of bacterial suspension:

[0124] The strains of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa were activated respectively, and then Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa were cultured on beef extract peptone agar medium for 24 hours. Single colonies were taken from each culture medium and cultured in an incubator with shaking for 12 hours. After dilution, 10 6CFU / mL of Escherichia coli suspension, Staphylococcus aureus suspension and Pseudomonas aeruginosa suspension.

[0125] (2) Determination of inhibition zone size:

[0126] Pour the prepared and sterilized beef extract peptone agar medium into sterile culture dishes, 15 mL per dish. After the culture medium cools and solidifies, transfer 0.1 mL of the above-prepared Escherichia coli suspension, Staphylococcus aureus suspension, and Pseudomonas aeruginosa suspension into different culture dishes and spread evenly with a spreader.

[0127] Using sterile tweezers, sterile, dry filter paper sheets with a diameter of 6.0 mm were placed in the compositions prepared in Examples 1-3 and Comparative Examples 1-2, respectively, and soaked for 30 minutes. The filter paper sheets were then removed and the excess liquid removed. Four filter paper sheets were then applied to each coated culture dish (one serving as a blank control). After incubation at room temperature for 20 minutes, the culture dishes were placed in an incubator for 24 hours. The diameter of the inhibition zone was measured using 0.05% Caeson CG as a positive control. Three replicates were performed for each group, and the average value was calculated.

[0128] Table 2

[0129]

[0130]

[0131] As can be seen from Table 2, the antibacterial abilities of the compositions prepared in Examples 1-3 were significantly higher than those of the compositions prepared in Comparative Examples 1-2, indicating that continuing the culture for 6-10 days can effectively improve the antibacterial ability.

[0132] Furthermore, from the comparison of Examples 1-3, it can be seen that when the culture time is continued for 8 days, the antibacterial ability of the prepared composition reaches the highest.

[0133] Experimental Example 5

[0134] The moisturizing properties of the compositions prepared in Examples 1-3 and Comparative Examples 1-2 were tested. The effects of the compositions prepared in Examples 1-3 and Comparative Examples 1-2 on the tissue dielectric constant (TDC) of the skin were as follows: Figure 4 As shown, the effects of the compositions prepared in Examples 1-3 and Comparative Examples 1-2 on epidermal water loss (TEWL) of the skin are shown in FIG. Figure 5 As shown; Figure 4 and Figure 5In the table, blank refers to skin that is not treated, sample refers to skin treated with the composition prepared in Examples 1-3 and Comparative Examples 1-2, Group 1 refers to the control group of the blank, water and the combination group of Comparative Example 1, Group 2 refers to the control group of the blank, water and the combination group of Comparative Example 2, Group 3 refers to the control group of the blank, water and the combination group of Example 2, Group 4 refers to the control group of the blank, water and the combination group of Example 1, and Group 5 refers to the control group of the blank, water and the combination group of Example 3.

[0135] The test methods for TDC and epidermal water loss are as follows: 10 volunteers aged 20-60 were selected, and a marker was used to divide the inner forearm of each volunteer into a blank area, a water-coated area, and a sample-coated area (the area of ​​each area was not less than 16 cm). 2 ); Apply water and sample accurately and evenly to the corresponding area on the inner forearm of the volunteer in the morning and evening (the application amount of the sample area is (2.00±0.05) mg / cm 2 ), after 14 days of continuous use, the MoistureMeterD deep moisture measurement XS5 probe was used to measure the skin parameter TDC, and the Vapometer was used to measure the skin epidermal water loss.

[0136] from Figure 4 and Figure 5 It can be seen that the compositions prepared in Examples 1-3 have relatively high water replenishment and moisturizing abilities, while the compositions prepared in Comparative Examples 1-2 have slightly poor water replenishment and moisturizing abilities, indicating that continuing the culture for 6-10 days can effectively promote water replenishment and improve moisturizing abilities.

[0137] Furthermore, from the comparison of Examples 1-3, it can be seen that when the culture time is continued for 8 days, the water replenishment promoting ability and moisturizing ability of the prepared composition reach the highest.
