Description

Technical Field

[0001] The invention belongs to the technical field of skin care products, and particularly relates to an eye mask for relieving eye fatigue and a preparation process thereof. Background Art

[0002] Prolonged excessive use of the eyes will cause excessive eye strain, eye fatigue, symptoms such as dry, uncomfortable, swollen and painful eyes and red bloodshot eyes. Prolonged or frequent eye fatigue will cause vision loss. Daily eye drops are a common means for people to eliminate fatigue, but these eye drops contain borneol to achieve a cool and comfortable effect, and adrenaline to constrict blood vessels to relieve congestion. However, these eye drops only have an effect and do not really relieve eye fatigue. On the contrary, frequent use of various eye drops may affect eye metabolism, aggravate existing eye diseases and increase intraocular pressure.

[0003] Therefore, external use products are safer. Among them, eye mask is a skin care product used for the skin around the eyes. The functions of daily prepared eye masks are mostly to eliminate dark circles and eye bags, moisturize and remove wrinkles. They have a certain effect in eliminating eye fatigue, but the effect is generally not obvious or only has a temporary effect for a short time.

[0004] Therefore, providing an eye mask that can relieve fatigue, revitalize eye skin, and tighten and anti-aging is a research focus in this field. Summary of the Invention

[0005] In view of the above problems, the object of the present invention is to provide an eye mask for relieving eye fatigue and a preparation process thereof.

[0006] The technical contents of the present invention are as follows:

[0007] An eye mask for relieving eye fatigue comprises the following components in parts by weight: 2.0-3.2 parts of plant active nano oil, 1.6-3.4 parts of polysaccharide gel solution, 6-9 parts of pure water, 1-6 parts of squalane, and 1-3 parts of yeast extract.

[0008] Yeast extract has the effects of promoting metabolism, moisturizing, anti-aging and inhibiting melanin;

[0009] Squalane promotes blood microcirculation and cell metabolism, enhances skin epidermal health and anti-aging effects;

[0010] The plant active nano oil is obtained by grinding and crushing five kinds of plant raw materials, vacuum distilling and static microfiltration, and has significant effects of refreshing, anti-fatigue, nourishing and repairing eye skin;

[0011] The plant raw materials comprise the following components in parts by weight: 6-9 parts of chrysanthemum, 1-3 parts of peony seeds, 0.9-2.9 parts of perilla, 1.4-2.5 parts of chuanxiong, and 2-4 parts of pine needles;

[0012] The volatile oil contained in the chrysanthemum used is one of the important active ingredients of chrysanthemum, which has the effects of clearing away heat and inflammation, relieving eye dryness, promoting diuresis and reducing swelling;

[0013] The volatile oil in the perilla contains a variety of amino acids such as linolenic acid and linalool, which can prevent cell oxidation, promote blood circulation and reduce blood coagulation. It also has the effects of tender skin, anti-aging and anti-wrinkle.

[0014] The peony seed oil used contains a variety of unsaturated acids and nutrients, which can protect against radiation, promote metabolism, promote blood circulation in the skin capillaries, and have the effect of refreshing the mind and improving sleep;

[0015] The Chuanxiong used contains volatile oils, alkaloids and other nutrients. It has a refreshing aroma, can dilate blood vessels, promote blood circulation, activate cells, and thus has anti-aging effects.

[0016] The pine needles used contain active oil that can promote blood circulation, remove blood stasis, eliminate swelling, refresh the mind, and effectively resist aging.

[0017] The polysaccharide gel solution is prepared by dissolving polysaccharide and acetyl glucosamine in water and then fully mixing and stirring. It has the effects of stretching the skin around the eyes, relieving stress and reducing fatigue.

[0018] Camellia sinensis flower polysaccharide is the active molecule of the tea tree, which has the effect of relieving stress and promoting blood circulation;

[0019] Hyaluronic acid is an acidic high-molecular sugar that moisturizes and soothes the skin around the eyes. It can improve blood circulation in the skin, thereby delaying skin aging.

[0020] Sodium alginate can increase the skin's water retention, firmness and elasticity, and repair pigmented skin caused by lack of sleep.

[0021] Acetyl glucosamine is a reducing monosaccharide belonging to the amino acid sugar class. It has the effect of inhibiting melanin synthesis, while also moisturizing and anti-aging.

[0022] The present invention also provides a method for preparing an eye mask for relieving eye fatigue, comprising the following steps:

[0023] Step 1: Add polysaccharide gel solution to the plant active nano oil and stir slowly under ultrasonic conditions;

[0024] The preparation method of the plant active nano oil specifically comprises the following steps:

[0025] S1 were cleaned plant materials, the peony seeds were ground and crushed and added to the remaining raw materials and stirred to obtain a plant slurry;

[0026] S2. The plant slurry obtained in step S1 was added to 10-15 times the volume of water and distilled under reduced pressure for 3-5h at a temperature of 70-80°C to obtain a distillate;

[0027] S3. The distillate was added to propylene glycol and microwaved for 12-24 hours, then allowed to stand for 1-3 days, and filtered through a microporous membrane to obtain plant active nano-oil;

[0028] The diameter of the microporous filter membrane is 0.45 μm;

[0029] The preparation method of the polysaccharide gel solution comprises the following steps: dissolving tea tree flower polysaccharide, sodium alginate, acetyl glucosamine and hyaluronic acid in 4-6 volume times of water, vortexing, and mixing uniformly to obtain the polysaccharide gel solution; the mass ratio of tea tree flower polysaccharide, hyaluronic acid, acetyl glucosamine and sodium alginate is 0.6-1.2:1.6-4.8:0.5-1.5:1-1.6.

[0030] Step 1: The slow stirring time is 4-6 hours;

[0031] Step 2: Mix the remaining raw materials and the microemulsion at a temperature of 50-60°C for 40-60 minutes to obtain an eye mask solution;

[0032] Step 3: After cooling to 35-45° C., immersing the matrix in the prepared eye mask solution to obtain an eye mask;

[0033] The matrix is ​​a hydrogel matrix.

[0034] The beneficial effects of the present invention are as follows:

[0035] The present invention is used for an eye mask for relieving eye fatigue. Multiple components work synergistically to effectively improve fatigue and eye problems. Plant active nano oil and polysaccharide gel solution are added. The raw materials for preparing the plant active nano oil include chrysanthemum, peony seed, perilla, Chuanxiong, and pine needle. The active nano oil prepared by compounding five plant raw materials contains rich nutrients such as metabolites, amino acids and unsaturated acids, which can effectively soothe eye muscles, promote eye blood circulation, balance nerves, tighten the skin, and achieve the effects of lowering intraocular pressure and eliminating fatigue. The added polysaccharide gel solution is made of polysaccharides and monosaccharides, can nourish and repair the skin, relieve eye pressure, and is compounded with the nano oil to relieve fatigue and reduce eye relaxation.

[0036] The present invention is a method for preparing an eye mask for relieving eye fatigue. First, the prepared plant active nano oil is extracted through a composite method of five plant raw materials, and microwaves and static conditions are used to separate and reprecipitate the components, and then microfiltration is performed. The molecules of effective ingredients such as terpenoids, olefins, alcohols, amino acids and aromatic substances contained in the plant raw materials are small and have a small difference in relative molecular weight, so they can be retained. Other substances with large molecular weight and difficult to absorb are separated and removed. The extracted active nano oil is purer and can effectively penetrate into the skin to exert the effect of eliminating fatigue and revitalizing the skin; the added polysaccharide gel solution fully stirs several polysaccharides and monosaccharides, and under the action of acidic polysaccharides, the amino polysaccharide and sodium alginate undergo a complex reaction to obtain a gel solution, which forms a protective film on the eyes, locks the active molecules, has a sustained-release effect, has little irritation to the eyes, and prevents the plant active nano oil from being oxidized and deteriorated when exposed to the air.

[0086] Efficacy verification

[0087] 1. Component Detection of Plant Active Nano-Oil

[0088] 1g of the plant active nano oil of Example 1 and Comparative Example 1 was taken and analyzed by gas chromatography mass spectrometry and detection institutions. The test results are as follows: Figure 1 As shown by Figure 1 It can be seen that the plant active nano oil prepared by the present invention has a high proportion of effective ingredients, and the terpenes, polysaccharides, olefins, amino acids, vitamins, unsaturated aliphatics, aromatics, flavonoids and alkanes contained are all higher than those in Comparative Example 1, while the content of other ingredients is relatively low.

[0089] 2. Fatigue Relief Test

[0090] Forty-five female rabbits of similar age and weight were divided equally into nine groups. The rabbits were immobilized and their intraocular pressure (IOP) was measured using a Sovey SW-500 rebound tonometer. Ketamine was then used to elevate IOP. After cleaning the area around the rabbits' eyes, the eye masks prepared in the Examples and Comparative Examples were applied around the eyes. A control group was treated with only saline solution. IOP was measured again 3 hours later, and the results were converted to kPa. The test results are shown in Table 1.

[0091] 45 female experimental rabbits of similar age and weight were prepared and divided into 9 groups. The rabbits' sleep was disturbed within 24 hours, so that they remained awake but their reactions became slow. Eight of the groups were then given eye masks, and the other group was not treated as a blank control. After 2 hours, the energy improvement changes of the rabbits in each group were evaluated. The scoring criteria for energy improvement changes were changes in reaction force and motor ability. The change in reaction force was the difference in reaction time to stimulation before and after the test, and the change in motor ability was the difference in jumping distance after encountering stimulation. The scoring criteria for energy improvement changes were 1-10 points. The test results are shown in Table 1.

[0092] Table 1

[0093]

[0094]

[0095] Note: *Compared with the control group, P<0.05.

[0096] As can be seen from the results in Table 1, the eye mask for relieving eye fatigue prepared by the present invention is added with active plant nano essential oils and polysaccharide gel solution obtained by microfiltration of a composite extraction of 5 plants. The prepared eye mask can effectively reduce the intraocular pressure of experimental rabbits, relieve eye fatigue, and improve their mental strength.

[0097] 3. Improve eye skin test

[0098] 80 volunteers with eye bags, dark circles, and fine lines were recruited. Each person had obvious eye problems and the degree was similar. They were divided into 8 groups, each with 10 people. Eyes were photographed before the test. Then, each group of volunteers applied the eye masks prepared in the examples and comparative examples once a day for 20 minutes after cleaning the eyes. The volunteers in each group had a uniform work and rest schedule. After 15 days, the volunteers' eyes were photographed again for evaluation. The photographing conditions were the same as the previous photographing conditions. The before and after comparison was used to evaluate the product performance based on the range and depth of dark circles, the range and depth of eye bags, the depth of fine lines, and the volunteers' experience. The results are shown in Table 2.

[0099] Table 2

[0100]

[0101]

[0102] As shown in Table 2, the eye mask prepared by the present invention can promote blood circulation, effectively improve dark circles and eye bags, tighten the eye skin, reduce fine lines, and effectively improve the condition of the eyes.

[0104] It can be seen from Comparative Examples 4-5 that the polysaccharide gel solution is prepared by dissolving tea tree flower polysaccharide, two other viscous polysaccharides and amino acid monosaccharides in water. It can firmly lock active molecules, effectively promote blood circulation, nourish the skin around the eyes, and improve eye problems.

[0105] In summary, the eye mask prepared by the present invention contains plant active nano-oil obtained by effective extraction and separation and purification, has plant-specific metabolites that calm the mind and refresh the brain, contains a variety of nutrients such as amino acids and unsaturated acids, has higher purity, can effectively penetrate the skin, promote blood circulation in the eyes, relieve eye muscle pressure, relieve fatigue, and improve eye problems; at the same time, the polysaccharide gel solution made from a variety of polysaccharides can form a water-locking and nourishing protective film on the eyes, nourish and stretch the skin around the eyes, improve fine lines, dark circles and other problems, and at the same time lock the active nano-oil molecules to prevent oxidation and deterioration. The two can work synergistically.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.
