Description

Technical Field

[0001] The invention relates to the technical field of antioxidant facial masks, in particular to an antioxidant facial mask containing pomegranate extract and a preparation method thereof. Background Art

[0002] Facial masks are a category of skin care products, used to hydrate the skin, and also have multiple functions such as moisturizing, nourishing, improving appearance, deep cleansing, etc. Facial masks are rich in nutrients, which can provide sufficient nutrition and moisture to the skin tissue and improve the elasticity and vitality of the skin.

[0003] There are a wide variety of plant secondary metabolites in pomegranate peel, and many of them have biological activity. Among them, the highest content is polyphenols, including ellagitannins, flavonoids, proanthocyanidins, etc. Punicic acid in pomegranate seed oil can reduce the catalytic oxidation activity of lipoxygenase and cyclooxygenase, and has the effect of inhibiting the production of human inflammation and the destructive effect of oxygen free radicals on the body. Adding pomegranate extract to a facial mask can improve the antioxidant and anti-aging effects of the mask, but the amount of liquid carried by the mask base cloth itself is limited, and the water-locking performance is also relatively general. During the process of applying the mask, the mask base cloth will dry out due to rapid water loss, which seriously shortens the application time and makes it difficult to achieve long-term skin care. Based on this, an antioxidant mask containing pomegranate extract and a preparation method thereof are proposed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an antioxidant facial mask containing pomegranate extract and a preparation method thereof. The addition of pomegranate extract enables the facial mask to have good antioxidant and anti-aging effects. The facial mask is then allowed to release functional substances for a long time to avoid rapid loss of water, thereby improving the quality of the facial mask.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an antioxidant facial mask containing pomegranate extract, comprising a modified facial mask base fabric and a facial mask liquid;

[0006] The facial mask liquid comprises the following components in percentage by mass: 3-8% of pomegranate peel extract, 5-10% of pomegranate seed extract, 2-6% of sodium hyaluronate, 0.1-0.2% of xanthan gum, 0.5-1.2% of emulsifier, and the balance of deionized water.

[0007] Preferably, the emulsifier is any one or more combinations of cetearyl alcohol, lauryl phosphate, and stearyl phosphate.

[0008] Preferably, the pomegranate peel extract is prepared as follows: the pomegranate peel is dried and ground, then the pomegranate peel powder is mixed with a 60wt% ethanol solution at a solid-liquid ratio of 1:10g / ml, ultrasonically treated at 45°C for 50min, and ethanol is removed by reduced pressure distillation to obtain the pomegranate peel extract.

[0009] Preferably, the pomegranate seed extract is prepared as follows: the pomegranate seeds are dried and ground, and the pomegranate seed powder is extracted using supercritical CO2 to obtain the pomegranate seed extract.

[0010] Preferably, the specific process of the supercritical CO2 extraction is: controlling the extraction temperature to 40°C, the extraction pressure to 28MPa, the separation temperature to 35°C, the separation pressure to 8MPa, and the extraction time to 3.5h.

[0011] Preferably, the modified facial mask base fabric is prepared as follows: S1, sequentially subjecting the facial mask base fabric to acid treatment and alkali treatment to obtain a pretreated base fabric; S2, passing the pretreated base fabric through a pool body filled with a nanocellulose suspension, and the extrusion rollers in the pool body perform an immersion and pressure treatment on the pretreated base fabric; S3, drying and cutting the pretreated base fabric leaving the pool body to obtain a modified facial mask base fabric.

[0012] Preferably, in step S1, the acid treatment is to immerse the mask base fabric in a 0.5wt% hydrochloric acid solution for 30 minutes, rinse it with deionized water and dry it after taking it out; the alkali treatment is to immerse the acid-treated mask base fabric in a 1wt% sodium hydroxide alcohol solution for 20 minutes, rinse it with deionized water and dry it after taking it out.

[0013] Preferably, in step S2, the mass concentration of the nanocellulose suspension is 2-5%.

[0014] Preferably, in step S2, the residence time of each part of the pretreated base fabric in the tank is 15-20 min; the pressure during the immersion and pressure treatment is 1.5-2 kg / cm 2 .

[0015] The present invention also provides a method for preparing an antioxidant facial mask containing pomegranate extract, comprising the following steps:

[0016] (1) stirring and mixing pomegranate peel extract, pomegranate seed extract, sodium hyaluronate, xanthan gum, an emulsifier and deionized water, and sterilizing them with ultraviolet light to obtain a mixed solution;

[0017] (2) The modified mask base fabric is sterilized by ultraviolet rays, the sterilized modified mask base fabric is placed in a packaging bag, and a mixed solution is injected into the packaging bag to prepare an antioxidant mask containing pomegranate extract.

[0018] The present invention provides an antioxidant facial mask containing pomegranate extract and a preparation method thereof, which has the following beneficial effects compared with the prior art:

[0019] The present invention adds pomegranate peel extract and pomegranate seed extract to the facial mask liquid, so that the facial mask has good anti-oxidation and anti-aging effects, and by modifying the facial mask base cloth to load a sufficient amount of facial mask liquid, the facial mask can release functional substances for a long time and avoid rapid loss of water, thereby improving the quality of the facial mask.

[0020] The present invention adopts acid-base treatment to the facial mask base cloth to destroy some fiber nodes, making it more fluffy after drying and improving the water absorption capacity; by loading nanocellulose on the facial mask base cloth, there are many exposed hydroxyl groups on the surface of the nanocellulose in a wet state, which can quickly combine with water molecules by hydrogen bonds. At the same time, a large number of hydroxyl groups are also distributed on the fiber macromolecules of the facial mask base cloth, and a three-dimensional network structure of facial mask base cloth-nanocellulose-water molecules cross-linked with each other is formed under the action of hydrogen bonds. These network structures can store more water inside and can also play a role in water retention, thereby improving the water absorption and water retention of the facial mask base cloth; the immersion and pressure treatment is conducive to the nanocellulose entering the interior of the facial mask base cloth fibers, increasing the load amount, and can further improve the water absorption and water retention capacity of the facial mask base cloth.

[0068] Quality Inspection

[0069] 1. Take the antioxidant masks in Examples 5-7 and Comparative Examples 1-4 as samples. A total of 70 volunteers with dark yellow skin, sagging skin and skin wrinkles, aged between 25-50, were recruited and randomly divided into 7 groups, with 10 people in each group. Apply once a day before going to bed, each application time is 20 minutes, and continue to apply for 21 days. Use a skin wrinkle tester and a skin color tester to detect the skin wrinkle area and color of the volunteers before and after the experiment, and calculate the improvement rate of skin color and skin wrinkles, improvement rate = difference before and after the experiment / detection value before the experiment × 100%; and calculate the average value of each group. The specific results are shown in the following table.

The water absorption N1 and water retention N2 of the sample were calculated according to the following formula:

[0074]

[0075] The test was performed 5 times and the average value was taken. The specific results are shown in the following table.
