[0002] At present, foundation and other base makeup products and sunscreen and other anti-aging products in cosmetics usually add a film-forming agent component, which can improve the skin adhesion and makeup retention of the base makeup product, and also form a film on the skin surface to improve the sunscreen effect of the sunscreen.

[0003] The film-forming agent currently used in cosmetics is usually derived from chemically synthesized film-forming agents. These chemical film-forming agents have certain stability and film-forming performance, but also have defects such as sticky skin feel, poor skin compatibility, and poor biodegradability. Compared with chemical synthetic film-forming agents, natural-source components are usually derived from plants and have the advantages of good skin-friendly effect and good biodegradability. However, there is a lack of natural-source film-forming agents with excellent film-forming performance in the current cosmetics. SUMMARY

[0022] Example 1

[0023] In view of the defect of lack of natural source film-forming agent in the current cosmetics, the present application provides a natural source film-forming composition, which comprises at least two of tremella polysaccharide, bletilla striata polysaccharide and peach gum polysaccharide.

Figures 16-18 ​As shown, the extraction process of tremella polysaccharide, bletilla striata polysaccharide and peach gum polysaccharide is improved in the embodiments of the present application; wherein the extraction process of tremella / bletilla striata / peach gum polysaccharide provided by the embodiments of the present application comprises: mixing tremella / bletilla striata / peach gum powder and water, and then sequentially performing leaching extraction and ultrasonic extraction, and obtaining polysaccharide after filtration; wherein the ratio of tremella powder and water is 1g:40-60ml, the leaching extraction time is 1h, the temperature is 60-80℃, and the ultrasonic extraction time is 30-50min; the ratio of bletilla striata powder and water is 1g:50-70ml, the leaching extraction time is 1-3h, the temperature is 50-70℃, and the ultrasonic extraction time is 40-60min; the ratio of peach gum powder and water is 1g:60-80ml, the leaching extraction time is 1-3h, the temperature is 100℃, and the ultrasonic extraction time is 40-60min; when the ratio of tremella powder and water is 1g:50ml, the leaching extraction time is 1h, the temperature is 80℃, and the ultrasonic extraction time is 50min, the extraction efficiency of tremella polysaccharide is best; when the ratio of bletilla striata powder and water is 1g:60ml, the leaching extraction time is 2h, the temperature is 50℃, and the ultrasonic extraction time is 60min, the extraction efficiency of bletilla striata polysaccharide is best; when the ratio of peach gum powder and water is 1g:80ml, the leaching extraction time is 3h, the temperature is 50℃, and the ultrasonic extraction time is 50min, the extraction efficiency of peach gum polysaccharide is best.

[0028] For the cosmetic category containing the natural source film-forming composition, foundation and sunscreen can be selected; the foundation is usually a cosmetic used for modifying and covering facial defects, and after film formation on facial skin or other exposed skin, it can cover the facial skin and cover the pigmentation such as freckles and liver spots on the skin, so that the facial skin appears natural and perfect, and the sunscreen cosmetic usually adds chemical or physical sunscreen active ingredients for absorbing or reflecting ultraviolet rays, and after film formation on facial skin or other exposed skin, it can reduce the damage and aging of skin structure caused by ultraviolet radiation.

[0029] Example 2

[0030] The embodiments of the present application provide examples of the film-forming effect of the natural source film-forming composition described in embodiment 1, including the screening of natural source polysaccharide, film formation and water and oil resistance performance test.

[0031] The screening process of the polysaccharide from natural sources includes the extraction of crude polysaccharide by the extraction steps of drying, crushing, sieving (40 mesh), extraction (the ratio of material to liquid is 1:50; the temperature is 45 DEG C; the time is 1 h), ultrasonic (30 min, power 40%), filtration (taking the filtrate), concentration (to the crystallization), alcohol precipitation (water: alcohol = 1:4), filtration (getting the residue), and drying. The results are expressed by the polysaccharide extraction rate. According to the polysaccharide content, the experimental raw materials are screened. The polysaccharide extraction rate is m / M*100%, m is the mass of polysaccharide after water extraction and alcohol precipitation and drying, and M is the mass of the initial weighed plant material powder. The screening results of the polysaccharide from natural sources are shown in Table 1.

[0032] Name Cactus Bletilla Astragalus Tremella Peach gum Laminaria Poria Polysaccharide content 15.5％ 11％ 1.26％ 5.3％ 15.94％ -- 2.38％

[0033] Table 1

[0034] As shown in Table 1, among the polysaccharide from fungi Tremella and Poria cocos and various plants, the polysaccharide content in Astragalus and Poria cocos is small, which is not suitable for being used as a film former. The polysaccharide from Laminaria has a fishy smell, which is also not suitable for being used as a film former. Therefore, the polysaccharide from Tremella, Bletilla striata, peach gum and cactus is selected as a film former.

[0035] The film forming performance test process includes the preparation of polysaccharide films by selecting 2% to 10% crude polysaccharide solution, and the formation of films by a common water-soluble chemical synthetic film former (3% PV / PA copolymer solution) on the market as a reference control. The dried crude polysaccharide and PV / PA copolymer are dissolved in distilled water, and the solution is dissolved in a 50 DEG C water bath. After cooling to room temperature, a proper amount of glycerol (25% of the dry matter) is added, and stirred for 15 minutes. The polysaccharide solution from Tremella with a mass fraction of 2%, the polysaccharide solution from peach gum with a mass fraction of 5%, the polysaccharide solution from Bletilla striata with a mass fraction of 3%, and the PV / PA copolymer solution are prepared, and poured into a disposable plastic flat plate (90 cm). The plate is dried in a drying oven at 50 DEG C overnight, and then placed in an environment with a temperature of 20 to 25 DEG C and a humidity (RH) of 60±5% for 24 h. The film forming effect is observed. The film forming performance test results are shown in Table 2. Figure 1 As shown in Table 2, the polysaccharide film from Tremella is white and slightly transparent, is brittle after drying, can be peeled off in a culture dish after absorbing moisture and softening, has elasticity and can be stretched, and has good film forming effect. The polysaccharide film from Bletilla striata is transparent, is brittle after drying, can be peeled off in a culture dish after absorbing moisture and softening, is hard but cannot be stretched, and has good film forming effect. The polysaccharide film from peach gum is transparent and yellow-brown, is brittle after drying, can be peeled off in a culture dish after absorbing moisture and softening, has elasticity and can be stretched, and has good film forming effect. The polysaccharide from cactus has poor film forming effect and cannot form a continuous film in a culture dish. Therefore, the polysaccharide from Tremella, Bletilla striata and peach gum is selected as a film former.

[0036] The water and oil resistance performance test process is tested by contact angle, including: the angle between the solid-liquid interface, the inside of the liquid to the gas-liquid interface is called the contact angle, the size of the contact angle is directly measured by using a contact angle measuring instrument, the shape of the liquid drop or bubble on the solid surface is observed, and the angle is measured by a protractor after drawing a tangent line at the intersection of the solid, liquid and gas; the commonly used water-based film-forming agent PV / PA copolymer on the market is used as a control, artificial sweat and artificial sebum are used to simulate human sweating, the contact angle of the liquid drop added on the glass piece with the film is measured by using a contact angle measuring instrument to preliminarily evaluate the water and sebum resistance of the film, the larger the contact angle, the better the water and sebum resistance of the film, and a water-soluble film-forming agent with certain waterproof and sweat-proof effect can be developed; a glass piece (2.5x7.5cm) is placed in a disposable plastic flat plate and fixed, the prepared polysaccharide solution is slowly poured into the flat plate, and the glass piece is covered with 20g of the polysaccharide solution, which is dried in a drying oven at 50°C overnight, and then placed in a room environment (temperature 20-22°C, humidity (RH) 50%-60%) for 24h to obtain a glass piece covered with a polysaccharide film for standby. The water and oil resistance performance test results are shown in Table 2 and Figures 2-3

[0037]

[0038] Table 2

[0039] As can be seen from Table 2 and Figures 2-3 , the water contact angle of peach gum and tremella polysaccharide film is greater than that of the conventional chemical synthetic film-forming agent PV / PA copolymer, indicating that the peach gum and tremella polysaccharide film-forming agent has excellent water resistance; at the same time, the artificial sebum contact angle of peach gum and tremella polysaccharide film is greater than that of the conventional chemical synthetic film-forming agent PV / PA copolymer, indicating that the peach gum and tremella polysaccharide film-forming agent has excellent oil resistance and can be used as a natural source film-forming agent; at the same time, considering that a low mass concentration of white and polysaccharide solution can form a polysaccharide film, and the formed white and polysaccharide film is transparent, smooth and not rough, and has a certain tensile capacity, and the content of white and polysaccharide is higher than that of tremella polysaccharide, which has a certain cost advantage and can also be used as a better film-forming agent raw material.

[0040] Example 3

[0041] The present application provides an example of the film-forming effect of the natural source film-forming composition described in Example 1, including single polysaccharide film-forming and water and oil resistance performance test, and compound polysaccharide film-forming and water and oil resistance performance test.

[0042] ​The single polysaccharide film-forming performance test process includes: accurately weighing three kinds of crude polysaccharide powders (Tremella fuciformis, Bletilla striata, and peach gum), preparing 3% Tremella fuciformis polysaccharide solution, 3% peach gum polysaccharide solution, and 5% peach gum polysaccharide solution, respectively, taking 20g of each solution and pouring them into a disposable plastic plate (90cm), drying them overnight in a drying oven at 50℃, and then placing them in an environment of 20~25℃ and 60±5% humidity (RH) for 24h to equilibrate, and then peeling off the film for later use;

[0043] The mechanical properties of the membrane were determined according to ASTM D 882-01. The main mechanical properties of the membrane include tensile strength (TS) and elongation at break (E%). These properties are primarily influenced by the molecular weight of the membrane material, the properties and content of the solvent and plasticizer. Different sources, molecular weights, properties, molecular chain structures, and lengths of the membrane material result in variations in the elasticity, flexibility, and tensile properties of the membrane after formation. Tensile strength is the maximum tensile force that the membrane can withstand in the tensile direction, expressed as tensile stress F. Elongation at break is the rate of change of displacement when the membrane breaks.

[0044] Sample pretreatment:

[0045] a. Select a clean and intact film and cut it into strips of 10×20mm;

[0046] b. Place the sample in an environment with a relative humidity of 65% ± 5% and a temperature of 20 to 25°C for 24 hours to equilibrate.

[0047] The calculation formula is as follows:

[0048]

[0049]

[0050] Where: TS - tensile strength, MPa; F - maximum tensile force at membrane rupture, N; S - cross-sectional area of ​​the membrane, mm 2 E - Elongation at break, %; L0 - Length of membrane sample, mm; L1 - Length of membrane at break, mm.

[0051] The film-forming properties test results of single polysaccharides are as follows: Figure 6 As shown, from Figure 6 It can be seen that the polysaccharides of tremella, Bletilla striata, and peach gum all have a certain tensile strength after forming a film, and the polysaccharides of tremella and peach gum also have a certain elongation at break after forming a film.

[0052] The testing process for the water and oil resistance properties of the chemical film-forming agent PV / PA copolymer and the single polysaccharide included: accurately weighing 5g of three crude polysaccharide powders (Tremella fuciformis, Bletilla striata, and peach gum), adding 95mL of water, dissolving in a 50℃ water bath, cooling to room temperature, adding 25% glycerol of the polysaccharide dry matter, stirring for 15min, and preparing a 5% (w / w) stock solution for later use; preparing Tremella fuciformis polysaccharide solutions with (w / w) of 0.5%, 0.75%, 1%, 2%, and 3% (w / w); Bletilla striata polysaccharide solutions with (w / w) of 0.25%, 0.375%, 0.5%, 0.75%, 1%, 2%, 3%, 4%, and 5% (w / w); and peach gum polysaccharide solutions with (w / w) of 0.5%, 0.75%, 1%, 2%, 3%, 4%, and 5% (w / w); and simultaneously preparing PV / PA copolymer solutions with (w / w) concentrations of 0.5%, 0.75%, 1%, 2%, 3%, 4%, and 5% (w / w).

[0053] Place a glass slide (2.5×7.5cm) in a disposable plastic plate and fix it in place. Select the polysaccharide solution prepared above and slowly pour 20g evenly into the plate to cover the glass slide. Dry it overnight in a drying oven at 50℃. Then place it in an indoor environment (temperature 20~22℃, humidity (RH) 50%~60%) for equilibration for 24h to obtain a glass slide covered with a polysaccharide film for later use.

[0054] Artificial sweat and artificial sebum were used to simulate human sweating. The contact angle of the droplets on glass slides coated with polysaccharide films of different concentrations was measured using a contact angle meter to preliminarily evaluate the water and sebum resistance of the films. The contact angle of the polysaccharide films formed by each individual component at different concentrations was used to determine the concentration of the film-forming agent to be used in the subsequent compounding of the three components.

[0055] The test results of the water and oil resistance properties of the chemical film-forming agent PV / PA copolymer and the monopolysaccharide are as follows: Figures 4-5 As shown, from Figures 4-5 It can be seen that within a certain concentration range, the water resistance of the film-forming agents of Tremella fuciformis, Bletilla striata, and peach gum increases with the increase of their mass concentrations. The contact angle reaches its maximum (81.67°) when the mass fraction of Tremella fuciformis polysaccharide solution is 0.75%, the contact angle reaches its maximum (69.56°) when the Bletilla striata polysaccharide solution is 1%, and the contact angle reaches its maximum (108.44°) when the peach gum polysaccharide solution is 1%. This indicates that when 0.75wt% Tremella fuciformis polysaccharide, 1wt% Bletilla striata polysaccharide, and 1wt% peach gum polysaccharide are combined as film-forming agents, their water resistance is the strongest. At the same time, the oil resistance of the films formed by Tremella fuciformis, Bletilla striata, and peach gum polysaccharides is better than that of the chemical film-forming agent PV / PA copolymer.

[0056] The test process of the complex polysaccharide film-forming and water and grease resistance includes: taking the film tensile strength, film elongation at break, and the contact angle between artificial sweat and the complex polysaccharide film as response values, taking the proportions of the three polysaccharides screened out as independent variables, using the DOE mixture experiment design simplex lattice design (enhanced by axis points and center points) in Minitab21 software to obtain 19 groups of complex polysaccharide film-forming agent formulations, optimizing the polysaccharide ratio for preparing the complex plant film-forming agent, and obtaining 19 groups of complex polysaccharide film-forming agent formulations as shown in Table 3.

[0059] Table 3

[0060] The analysis results of the film tensile strength as the response in the complex polysaccharide mixture experiment model establishment and significance test are shown in Table 4. Figures 7-9 The analysis process includes: after the statistical analysis of the film tensile strength data in Table 4 by using Minitab21 software, multiple regression fitting is performed to obtain the regression equation: Y1 = 1.5861A + 0.4851B + 0.7859C + 9.713AB + 1.8AC + 8.501BC + 13.88ABC. The residual of the film tensile strength is Figure 7 , the residual and the observed value data are randomly distributed, there is no obvious upward or downward trend, the residual and the fitted value data are normal, there is no obvious horn shape, and the data distribution of the normal probability chart is basically on a straight line, indicating that the data is normally distributed. The regression and variance analysis results of the film tensile strength are shown in Table 4. The linear relationship between the dependent variable and the independent variable of the equation is obvious, the regression model is significant (P < 0.01), the determination coefficient R 2 = 0.9909, R 2 Adj = 0.9863, indicating that the model is well fitted with the experiment.

[0061] From Table 4, the interaction of main materials AB (tremella and baiji polysaccharide), BC (baiji and peach gum polysaccharide), and ABC (tremella, baiji and peach gum polysaccharide) was extremely significant (P < 0.01), and the interaction of AC (tremella and peach gum polysaccharide) was significant (P < 0.05), indicating that the four interactions could significantly affect the tensile strength of the film. The response surface graph showed that the response surface was a curved surface rather than a flat surface, indicating that there was an interaction between the three. According to the regression equation, the K values of AB (K = 9.713), AC (K = 1.8), and BC (K = 8.501) were greater than 0, indicating that the three interactions could significantly improve the tensile strength of the film. The closer the color of the contour graph to dark green, the higher the value, indicating a higher contribution rate to the tensile strength of the film. The closer the color to blue, the lower the value, indicating a lower contribution rate to the tensile strength of the film. According to the regression equation coefficients, the contribution rate of the three main materials was highest for tremella polysaccharide, followed by peach gum polysaccharide and baiji polysaccharide. The contour graph was concentric, indicating that there was an optimal solution. When the content ratio of tremella: baiji: peach gum was 0.3838: 0.4042: 0.2120, the maximum tensile strength of the polysaccharide film was 3.8098 Mpa, and the optimization desirability d = 95.25%.

[0074] In Table 6, * represents p<0.05; ** represents p<0.01.

[0075] Tremella polysaccharide, bletilla striata polysaccharide and peach gum polysaccharide have excellent film forming effect, but the film properties are different, and there is a negative correlation between the tensile strength and the elongation at break of the film, the greater the tensile strength, the smaller the elongation at break, on the contrary, the smaller the tensile strength, the softer the film, the greater the elongation at break, the softer the film forming agent, and the more sticky the skin feel in the added cosmetics, which cannot give the skin a refreshing feeling, and the harder the film forming agent, that is, the lower the elongation at break, the more tight the film forming process when added to the cosmetics, therefore, the softness and holding effect of the compounded polysaccharide film forming agent should be considered, that is, the proportion of the tensile strength, the elongation at break and the contact angle of the formed film, so that the compounded film forming agent can achieve the holding effect and improve the comfort of the skin after makeup, according to the contour graph of the equal value between the tensile strength, the elongation at break and the contact angle and the compounded proportion, the tensile strength range is 3.0-3.5 Mpa, the elongation at break range is 120%-150%, and the contact angle range is 85-90°, the response optimization is carried out, when the mass content is 0.2 of tremella polysaccharide, 0.25 of bletilla striata polysaccharide and 0.55 of peach gum polysaccharide, the predicted tensile strength is 3.105 Mpa, the elongation at break is 125.242%, and the contact angle is 86.146°. The film forming verification of the compounded polysaccharide film is carried out, the tensile strength of the film is 3.18 Mpa, which is different from the predicted value by 2.415%; the elongation at break of the film is 126.2%, which is different from the predicted value by 1.08%; the contact angle is 86.03°, which is different from the predicted value by 0.14%, the relative error between the theoretical value and the experimental data is less than 3%, which confirms that the model is suitable for predicting the change of the tensile strength, the elongation at break and the contact angle size under any combination of the three variables, and the accuracy is high.

[0076] Example 4

[0077] In view of the low extraction efficiency of traditional water extraction and alcohol precipitation method for extracting plant polysaccharide, the extraction process of tremella polysaccharide, bletilla striata polysaccharide and peach gum polysaccharide in the natural source film forming agent composition is optimized in this example 4.

[0078] Compared with the traditional water extraction and alcohol precipitation method for extracting plant polysaccharide, the ultrasonic frequency of the ultrasonic extraction method can promote the hydration of plant materials to cause the expansion of cell wall pores, thereby causing the rupture of cell wall, and increasing the movement speed and frequency of substance molecules, so as to enhance the penetration of solvent, thereby improving the rate of target components into the solvent, so that the extraction is successfully carried out; therefore, the traditional water immersion extraction is assisted by ultrasonic extraction method in this application example, which not only saves time but also improves efficiency, and on the basis of single factor experiment and orthogonal experiment for optimizing the extraction rate, the polysaccharide yield is taken as the evaluation index, and the sugar content of polysaccharide is determined, and the ultrasonic assisted hot water immersion extraction process is optimized.

[0079] The process of optimizing the extraction process includes: accurately weighing 10 g of tremella fruiting body and white and peach gum plant powder, adding 200 mL of water, setting the extraction temperature to 40°C, the extraction time to 1 h, and the ultrasonic extraction time to 30 min, then filtering, taking the filtrate, and obtaining the crude polysaccharide extract. The crude polysaccharide extract is concentrated to 1 / 3 of the volume by rotary evaporation, and then anhydrous ethanol (concentrate: ethanol = 1:4) is added. After standing overnight, the precipitate is obtained, dried, and the polysaccharide dry product is obtained, and the mass is measured.

[0080] The effects of liquid-solid ratio (20:1, 30:1, 40:1, 50:1, 60:1, 70:1, 80:1 (mL:g)), extraction time (0, 0.5, 1, 2, 3, 4, 5 h), extraction temperature (40, 50, 60, 70, 80, 90, 100°C), and ultrasonic time (20, 30, 40, 50, 60 min) on the polysaccharide yield were investigated under initial conditions.

[0081] Then, the ultrasonic time, liquid-solid ratio, and extraction temperature parameters of the ultrasonic-assisted hot water extraction process for 10 g of tremella polysaccharide are set according to Table 7; the liquid-solid ratio, ultrasonic time, extraction temperature, and extraction time parameters of the extraction process for 10 g of white and polysaccharide are set according to Table 8; the liquid-solid ratio, extraction time, and ultrasonic time parameters of the extraction process for 10 g of peach gum polysaccharide are set according to Table 9.

[0087] Table 9

[0088] The test results of ultrasonic-assisted hot water extraction are shown in Figures 4-6 as shown in Figures 4-6It can be seen that the yield of tremella polysaccharide is different under different extraction conditions. Within the range of ultrasonic time 20-60 min, liquid-to-material ratio 20-60, and extraction temperature 40-80℃, the yield of polysaccharide increases first and then decreases with the increase of factor level, and the yield of polysaccharide reaches the peak value when the ultrasonic time is 40 min, the liquid-to-material ratio is 50:1, and the extraction temperature is 70℃. The extraction time has little effect on the yield of tremella polysaccharide. The superior extraction conditions of tremella polysaccharide are liquid-to-material ratio 40-60, extraction time 1h, extraction temperature 60-80℃, and ultrasonic time 30-50 min.

[0089] The test data of ultrasonic-assisted hot water extraction were subjected to variance analysis with the extraction rate of tremella polysaccharide as the evaluation index, and the results are shown in Table 10.

[0090]

[0091] Table 10

[0092] As can be seen from Table 10, the effects of ultrasonic time, liquid-to-material ratio, and extraction temperature on the extraction rate of tremella polysaccharide gradually decrease. The optimal extraction process of tremella polysaccharide is determined in this embodiment as liquid-to-material ratio 50:1, extraction time 1h, extraction temperature 80℃, and ultrasonic time 50 min.

[0093] 5g of tremella powder was weighed into 5 portions, and extracted under the extraction conditions of liquid-to-material ratio 50:1, extraction time 1h, extraction temperature 80℃, and ultrasonic time 50 min. The extraction efficiency of tremella polysaccharide is shown in Table 11.

[0094]

[0095]

[0097] As can be seen from Table 11, the extraction efficiency of tremella polysaccharide extracted by the optimal extraction process determined in this embodiment is about 17%, which is much higher than the extraction efficiency of 5.3% of traditional tremella polysaccharide.

[0098] The yield of bletilla striata polysaccharide is different under different extraction conditions. Within the range of ultrasonic time 20-60 min, liquid-to-material ratio 30-70, extraction temperature 40-80℃, and extraction time 0-3h, the yield of polysaccharide increases first and then decreases with the increase of factor level, and the yield of polysaccharide reaches the peak value when the ultrasonic time is 50 min, the liquid-to-material ratio is 60:1, and the extraction temperature is 60℃. The superior extraction conditions of bletilla striata polysaccharide are ultrasonic time 40-60 min, liquid-to-material ratio 50-70, extraction temperature 50-70℃, and extraction time 1-3h.

[0099] The variance analysis was made on the test data of ultrasonic-assisted hot water extraction with the extraction rate of Bletilla striata polysaccharide as the evaluation index, and the results are shown in Table 12.

[0101] Table 12

[0102] As shown in Table 12, the influence degree of ultrasonic time, extraction temperature, extraction time and solid-liquid ratio on the extraction rate of Bletilla striata polysaccharide decreases in turn, and the optimal extraction process of Bletilla striata polysaccharide is determined as follows: solid-liquid ratio 60:1, extraction time 2h, extraction temperature 50℃ and ultrasonic time 60min.

[0103] 5g of Bletilla striata powder was weighed into 5 portions, and the extraction was carried out under the extraction conditions of solid-liquid ratio 60:1, extraction time 2h, extraction temperature 50℃ and ultrasonic time 60min, and the extraction efficiency of Bletilla striata polysaccharide is shown in Table 13.

[0104]

[0105] Table 13

[0106] As shown in Table 13, the extraction efficiency of Bletilla striata polysaccharide extracted by the optimal extraction process determined in the embodiment is about 55%, which is much higher than the extraction efficiency of 11% of traditional Bletilla striata polysaccharide.

[0107] The peach gum polysaccharide yield is different under different extraction conditions. Within the range of ultrasonic time 20-60min and solid-liquid ratio 30-80, the polysaccharide yield increases first and then decreases with the increase of the factor level, and the polysaccharide yield reaches the peak value when the ultrasonic time is 50min and the solid-liquid ratio is 70:1; the extraction time has little effect on the extraction rate of peach gum polysaccharide, and the extraction rate slightly decreases with the increase of the time, therefore, the superior extraction conditions of peach gum polysaccharide are selected as follows: solid-liquid ratio 60-80, extraction time 1-3h, extraction temperature 100℃ and ultrasonic time 40-60min.

[0108] The variance analysis was made on the test data of ultrasonic-assisted hot water extraction with the extraction rate of peach gum polysaccharide as the evaluation index, and the results are shown in Table 14.

[0109]

[0110] Table 14

[0111] As shown in Table 14, the influence degree of extraction time, ultrasonic time and solid-liquid ratio on the extraction rate of peach gum polysaccharide decreases in turn, and the optimal extraction process of peach gum polysaccharide is determined as follows: solid-liquid ratio 80:1, extraction time 3h and ultrasonic time 50min.

[0112] The 5 g peach gum powder was weighed, and extraction was carried out according to the liquid-material ratio of 80:1, extraction time of 3 h and ultrasonic time of 50 min. The extraction efficiency of white yam polysaccharide is shown in Table 15.

[0113]

[0114] Table 15

[0115] As can be seen from Table 15, the extraction efficiency of peach gum polysaccharide extracted by the optimal extraction process of this embodiment is about 45%, which is much higher than the extraction efficiency of 15% of traditional peach gum polysaccharide.

[0116] Experimental Example 1

[0117] In this experimental example 1, the moisturizing and makeup performance of the natural source film-forming agent composition compounded by tremella polysaccharide, white yam polysaccharide and peach gum polysaccharide is verified, wherein the tremella polysaccharide, white yam polysaccharide and peach gum polysaccharide in the natural source film-forming agent composition are configured in a mass ratio of 0.2:0.25:0.55.

Multiple areas can be marked on the same arm (with a 1cm interval). The test samples and blank controls are randomly distributed on the left and right arms. After waiting for 10 minutes, the initial water content of the arms in the two areas is tested. Each test site is coated with an amount of (2.0±0.1) mg / cm 2 , and the skin moisture content of the test sample area and the blank area is measured at 0.5h, 4h and 8h after coating, respectively. The change amount (△ difference) after using the product is T after use-T before use; the change rate after using the product is (T after use-T before use) / T before use*100%.

[0120] The measured values at different time points were compared with the base values (before and after use) using SPSS analysis software. Shapiro-Wilk Test was used for significance test of normal distribution of data improvement values. If p (two-sided) > 0.05, it was normally distributed, and paired sample t-test was performed with a significance difference level α of 0.05. If p (two-sided) < 0.05, it was non-normally distributed, and Wilcoxon signed rank test was performed with a significance difference level α of 0.05.

[0121] The test area and the control area (between groups) at different time points were compared. Shapiro-Wilk Test was used for significance test of normal distribution of data improvement values (test area difference - control area difference). If p (two-sided) > 0.05, it was normally distributed, and paired sample t-test was performed with a significance difference level α of 0.05. If p (two-sided) < 0.05, it was non-normally distributed, and Wilcoxon signed rank test was performed with a significance difference level α of 0.05.

Respectively take three kinds of foundation liquid 0.01g on glass slide (2.5×7cm) and smear evenly, then dry (50℃, 24h), use contact angle measuring instrument to measure the contact angle of artificial sweat and artificial sebum and foundation liquid film, and record the data; using subjective evaluation scoring method for human body makeup retention test, the foundation liquid without adding complex plant film-forming agent is formula A group; the foundation liquid formula adding 5% complex plant film-forming agent is formula B group; the subjects are 22-42 year-old volunteers, the test time is 8h, the subjective evaluation dimension and scoring rules are shown in table 18, and the subjective evaluation dimension of makeup retention is shown in table 19.
