Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of cosmetics, and particularly relates to an eye cream containing an effective composition for improving eye skin problems and a preparation method thereof. Background Art
[0002] Aging is a physiological and functional degeneration caused by various genetic and environmental factors, which ultimately affects the internal environment of biological organisms, destroys the balance of the internal microenvironment and increases susceptibility to diseases. Among them, skin aging is inevitable, and its specific manifestations include: tissue atrophy, fragility, repair defects, immune deficiency and susceptibility to infection. Skin aging can lead to a series of adverse consequences, such as water loss, dry or peeling skin, pigmentation, wrinkles, etc. The aging level is getting higher and higher, and the problem of skin aging is getting more and more serious, making people's demand for skin anti-aging more and more intense. The aging of the body will lead to a decrease in the number of stem cells and a decrease in cell activity. Although skin aging is inevitable, the speed of aging can be slowed down to a certain extent through technical intervention. Flavonoids and polyphenols in plant extracts have strong antioxidant properties and can effectively delay aging. In addition, the acid substances and biological enzymes therein can also effectively inhibit the activity of elastase and promote the production of collagen, which has a certain effect of delaying aging. Summary of the invention
[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and thus provide a repair composition that can effectively resist aging, reduce wrinkles, enhance skin elasticity, increase the moisture content of the stratum corneum, whiten the skin and is mild and non-irritating.

[0052] The oil is one or more of cetearyl alcohol, dimethicone, and caprylic / capric triglyceride.
[0053] In a third aspect of the present invention, the present invention provides a method for preparing an eye cream, the preparation method specifically comprising the following steps:
[0054] S1: Evenly mix Acer truncatum extract, Ginger zingiber officinale extract, Dendrobium candidum extract, Pinus truncatula bark extract, and Epilobium freiherbii extract to obtain a repairing composition;
[0055] S2: Add the moisturizer and thickener into the emulsifying pot, heat to 70-90°C, stir evenly, and obtain phase A;
[0056] S3: Add surfactant and oil into an oil pan, heat to 70-90°C, stir and add into phase A to obtain phase B;
[0057] S4: Add the pH adjuster, preservative and repair composition into phase B, cool to room temperature, stir evenly to obtain eye cream.
[0058] Compared with the prior art, the present invention has the following beneficial effects:
[0059] The present invention provides a repairing composition, in which five extracts can cooperate with each other and synergistically enhance the effects, thereby achieving anti-aging effects, improving the mobility of skin cells, and being overall mild and non-irritating.
[0060] Specifically, the present invention innovatively selects specific mass fractions of Acer truncatum extract, Ginger extract, Dendrobium candidum extract, Pinus bark extract, and Epilobium freiherb extract in combination to prepare a repair composition, in which the components can cooperate with each other and synergize to solve the problems of skin sagging, aging, dark complexion, increased wrinkles, etc. caused by external environmental factors. Specifically, the repair composition provided by the present invention can effectively improve skin elasticity, reduce skin wrinkles, increase skin cell mobility, whiten, and increase cell water content.
[0061] Specifically, in the composition used in the present invention, the red maple extract, the red ginger extract, the dendrobium candidum extract, the North American pine bark extract and the epilobium freicherii extract all have good antioxidant activity. They can jointly protect skin cells from damage caused by external factors such as ultraviolet rays by scavenging free radicals and reducing oxidative stress, thereby playing a synergistic role in anti-wrinkle and whitening.
[0062] Ginger extract, Dendrobium officinale extract and North American pine bark extract can inhibit the expression of matrix metalloproteinases (MMPs). By jointly inhibiting the expression of MMPs, they reduce the degradation of collagen and thus exert a synergistic effect in anti-wrinkle.
[0063] Dendrobium officinale extract and Ginger extract can promote the synthesis of collagen, increase the collagen content in the skin, improve skin elasticity, and reduce wrinkles, thus playing a synergistic role in anti-wrinkle.
[0064] Both red maple extract and red ginger extract have the effect of inhibiting tyrosinase activity, which is the key enzyme in the production of melanin. By jointly inhibiting tyrosinase activity, the production of melanin is reduced, thus exerting a synergistic effect in whitening.
[0065] Dendrobium officinale extract can protect collagen homeostasis and reduce skin damage by regulating the TGFβ / Smad pathway. This regulatory effect may work synergistically with other extracts to improve skin conditions and enhance anti-wrinkle and whitening effects.
[0066] In addition, the repair composition provided by the present invention is mild and non-irritating as a whole, has a wide range of applicable objects, and has a simple preparation method, and is suitable for actual production. DETAILED DESCRIPTION

[0085] The surfactant is glyceryl stearate citrate and PEG-100 stearate, and the mass ratio thereof is 1:0.7;
[0086] The moisturizing agent is sodium hyaluronate and butylene glycol, and the mass ratio thereof is 0.1:5;
[0087] The preservatives are hydroxyacetophenone, 1,2-hexanediol, and 1,2-pentanediol, and the mass ratio thereof is 0.4:0.5:1;

[0091] Eye cream preparation method:
[0092] S1: Evenly mix Acer truncatum extract, Ginger zingiber officinale extract, Dendrobium candidum extract, Pinus truncatula bark extract, and Epilobium freiherbii extract to obtain a repairing composition;
[0093] S2: Add the moisturizer and thickener into the emulsifying pot, heat to 80°C, and stir evenly to obtain phase A;
[0094] S3: Add surfactant and oil into an oil pan, heat to 74°C, stir and add into phase A to obtain phase B;
[0095] S4: Add the pH adjuster, preservative and repair composition into phase B, cool to room temperature, stir evenly to obtain eye cream.
[0096] Test 1: Cell migration assay
[0097] The cell migration effects of compositions 1-3 and ①-⑩ were verified.
[0098] The degree of cell migration has an important impact on wound healing and skin repair. In the process of wound healing, cell migration is an important step for epidermal cells to cover the wound, so the higher the cell migration rate, the faster the wound heals. At the same time, cell migration is also involved in the repair process after skin damage. If cell migration is impaired, it will lead to skin repair disorders, which in turn cause various skin diseases.
[0099] Press 1*10 6 Hacat cells were inoculated into 12-well plates at a unit inoculation density and incubated overnight in a 37°C, 5% CO2 incubator. When the cell plating rate in the 12-well plate reached about 80%, the sample group and the blank control group were scratched. After the scratching, the cells were washed with PBS to remove dead cells, and fresh SCF-free keratinocyte culture medium was added. 50 μL of composition 1-3 and ①-⑩ (with deionized sterile water as solvent) was added to each well at a concentration of 50 mg / L. An equal amount of deionized sterile water was used as a blank control. An inverted microscope was used to take pictures and record them. The cells were incubated in a 37°C, 5% CO2 incubator for 24 hours, and pictures were taken again. ImageJ software was used for statistical analysis. Three parallel experiments were performed in each sample group and blank control group, and the results were averaged.
[0100] Table 3 Cell migration rate
[0101] Composition Average migration rate / % 1 58.42 2 55.37 3 56.64 ① 35.17 ② 28.64 ③ 25.32 ④ 35.41 ⑤ 34.27 ⑥ 10.36 ⑦ 8.62 ⑧ 9.94 ⑨ 10.93 ⑩ 9.47 blank 0.42
[0102] It can be seen from Table 3 that when the technical solution of the present invention is adopted, the obtained composition has a significant cell migration rate, and when the raw material components are missing, the cell migration rate of the obtained composition is significantly reduced.
[0103] Test 2: Tyrosinase inhibition test
[0104] The tyrosinase inhibition test was used to verify the tyrosinase inhibition ability of compositions 1-3, ①-⑩.
[0105] Tyrosinase is a key enzyme in the synthesis of melanin. Inhibiting it can effectively reduce the synthesis of melanin and play a whitening role.
[0106] The test method refers to T / GDCA 006-2021 "Guangdong Cosmetics Association Group Standard-Test Method for Tyrosinase Activity Inhibition of Cosmetic Raw Materials (In Vitro Method)".
[0107] Test samples: Compositions 1-3, compositions ①-⑩, concentration: 50 mg / L (deionized sterile water as solvent), blank is an equal amount of deionized sterile water;
[0108] Kojic acid concentration: 0.005g / L.
[0109] Table 4 Tyrosinase inhibition rate
[0110] Composition Inhibition rate% 1 74.52±1.37* 2 73.46±0.94* 3 73.93±1.56* ① 43.51±2.31* ② 41.36±1.16* ③ 38.62±1.04* ④ 40.51±0.74* ⑤ 36.82±0.95* ⑥ 12.51±0.93* ⑦ 9.26±1.26* ⑧ 8.51±1.42* ⑨ 4.31±2.61* ⑩ 6.55±0.97* Kojic Acid 100* blank 0.12
[0111] Note: "*" indicates significant difference compared with the blank group, P value < 0.05.
[0112] According to the results of compositions 1-3 in Table 4, the repair compositions provided by the embodiments of the present invention have a good tyrosinase inhibition effect, especially composition 1 has a better effect.
[0113] Comparing the results of composition 1 with compositions ①-⑩, it can be seen that the use of the repair composition with a specific combination and a specific ratio of the present invention can significantly enhance the tyrosinase inhibition effect, and there is a synergistic effect between the raw materials in the repair composition of the present invention.
[0114] Experiment 3: Human efficacy test
[0115] The eye cream prepared by the present invention was subjected to an 8-week anti-aging test according to the method described in the literature (Zhu Liping et al., Clinical Efficacy Test and Analysis of Ginseng Anti-aging Mask [J], Chinese Journal of Aesthetic Medicine, 2016, 25(02): 33-36).
[0116] Ten volunteers were selected for each application case.
