Description

Technical Field

[0001] The invention relates to the technical field of facial masks, in particular to an anti-inflammatory and anti-allergic facial mask containing plant extracts and a processing technology thereof. Background Art

[0002] As people age and experience stress, their facial skin will gradually begin to dry out, become allergic, and have fine lines. In order to improve the condition of facial skin, more and more facial masks are being developed. Facial masks can dilate the pores of the skin, speed up metabolism, and increase the oxygen content of the skin. The nutrients in the facial masks penetrate into the stratum corneum of the epidermis of the skin, making the skin soft. Facial masks are an important part of skin care. Regularly applying facial masks according to the characteristics of various skin types can degrease oily skin, shrink large pores, restore the luster of dry and wrinkled skin, and inhibit inflammation of acne skin.

[0003] However, some people have allergic skin, which means that when the skin is exposed to various stimuli, such as cosmetics that may cause adverse reactions, pollen, polluted air, etc., the skin is prone to abnormal phenomena such as redness, itching, peeling, and allergic dermatitis. Therefore, this group of people has higher requirements for the ingredients of the mask; in addition, there are some people suffering from dermatitis eczema, hormone-dependent dermatitis, etc., and they also have higher requirements for the mask.

[0004] Currently, the main function of most facial masks on the market is whitening and moisturizing, while there are relatively few facial masks for allergic skin or with anti-inflammatory effects. Therefore, developing a facial mask that has anti-inflammatory and anti-allergic effects in addition to basic care is highly in line with market demand. Summary of the invention

[0005] The object of the present invention is to provide an anti-inflammatory and anti-allergic facial mask containing plant extracts and a processing technology thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An anti-inflammatory and anti-allergic facial mask containing plant extracts, comprising a facial mask liquid and a facial mask cloth.

[0008] Preferably, the facial mask cloth includes but is not limited to any one of gauze, silk cloth, and cotton cloth. Silk cloth is preferred in the present invention because: silk cloth is more skin-friendly, mild and non-irritating, and is not easy to cause skin allergies and itching; at the same time, silk is a light and soft porous natural fiber that can absorb the facial mask liquid as much as possible. The mask will not feel oppressive or tight when used, and can also tightly fill the grooves of the skin, so that the face can comfortably and evenly absorb the essence of the facial mask liquid, thereby better playing an anti-inflammatory and anti-allergic role.

[0009] Preferably, the facial mask liquid comprises the following components: by weight, 8-16 parts of Physalis berry extract, 4-8 parts of grape seed extract, 2-4 parts of hydrolyzed proanthocyanidins, 0.05-1 part of tetrahydromethylpyrimidine carboxylic acid, 0.1-0.5 part of carboxymethyl chitosan, 10-20 parts of cucumber fruit water, 0.1-0.3 part of sodium hyaluronate, 1-5 parts of propylene glycol, and 60-80 parts of purified water.

[0010] Preferably, the preparation method of the Physalis berry extract is: after crushing the Physalis berry pulp, add it to ten times the weight of a 60-80wt% ethanol solution, reflux extract at 60-80°C for 2-3 times under light protection, each time for 1-2 hours, filter, combine the filtrate, and recover ethanol by decompression to obtain the Physalis berry extract.

[0011] Preferably, the preparation method of the grape seed extract is as follows: (1) crushing the grape seeds, adding them to ten times the weight of a 60-80wt% ethanol solution, refluxing and extracting at 60-80°C for 2-3 times, each time for 1-2 hours, filtering, combining the filtrates, and recovering the ethanol by decompression to obtain the grape seed extract.

[0012] Preferably, the grape seed extract needs to be further treated by the following method: (1) adding the grape seed extract to 10 times the weight of an ethanol solution containing hydrochloric acid, reflux reaction at 75-85° C. for 1-3 hours, ending the reaction, adding water and an organic solvent, extracting, washing, drying, and recovering the organic solvent under reduced pressure to obtain product A; (2) adding product A to 10 times the weight of an ethanol solution containing urea, reflux reaction at 75-85° C. until the solution is clear and transparent, then cooling to 2-6° C., standing for 12-18 hours, and filtering to obtain a filtrate. , then add an organic solvent and a hydrochloric acid solution to the filtrate, adjust the pH of the filtrate to 3-4, add water, extract, wash, dry, and recover the organic solvent under reduced pressure to obtain product B; (3) place product B on the top of a silica gel column, elute with an acetone-petroleum ether solution at a flow rate of 2-5 mL / min, and collect product C; (5) prepare a solvent system, adjust the solvent system to 50-60° C., then add product C thereto, mix and stir for 5-10 minutes, recover the solvent under reduced pressure, wash, and dry to complete the treatment to obtain the treated grape seed extract.

[0013] Preferably, in the ethanol solution containing hydrochloric acid, the volume percentage concentration of hydrochloric acid is 3 to 5 v / v%.

[0014] Preferably, in the ethanol solution containing urea, the mass percentage concentration of urea is 15-20wt%.

[0015] Preferably, in the acetone-petroleum ether solution, the mass ratio of acetone to petroleum ether is 85:15.

[0016] Preferably, the solvent system is obtained by mixing ethyl acetate, n-butanol, ethanol and water in a mass ratio of 5:5:1:10, and then adding citric acid to adjust the pH to 5±0.5.

[0017] Preferably, the grape seed extract is prepared under light-protected conditions because grape seed extract contains a large amount of linoleic acid, which has a very strong reducing property and is easily oxidized by ultraviolet light.

[0018] Preferably, the processing technology of the anti-inflammatory and anti-allergic facial mask containing plant extracts comprises the following steps:

[0019] Step 1: (1) Heat the physalis extract, grape seed extract, tetrahydromethylpyrimidine carboxylic acid, carboxymethyl chitosan, sodium hyaluronate, propylene glycol and purified water to 30-50° C. in a dark environment, and stir for 30-60 minutes to mix evenly; (2) Add hydrolyzed proanthocyanidins and cucumber fruit water to (1), stir for 30-60 minutes to mix evenly, and wait for it to cool to room temperature to obtain a facial mask solution;

[0020] Step 2: In a dark environment, soak the mask cloth in the mask liquid for 12 to 24 hours, and then package it to obtain an anti-inflammatory and anti-allergic mask containing plant extracts.

[0021] According to medical records, physalis berries have the effects of clearing heat, detoxifying and anti-inflammatory, and are therefore widely used in medical treatment. Therefore, the present application designs the application of physalis berries to facial masks to achieve the anti-inflammatory effect on the face. In the scheme, both physalis berries and grape seeds are extracted to obtain physalis berry extract and grape seed extract.

[0022] Among them, the extract of Physalis berry contains rich anti-inflammatory nutrients, especially flavonoids and alkaloids. Flavonoids can downregulate the expression level of inflammatory mediators, and alkaloids can regulate the production and release of inflammatory cytokines. The two work together to play a positive anti-inflammatory role; and both can destroy the cell membrane of bacteria, thereby causing the extravasation of intracellular substances, killing bacteria, playing an antibacterial role, and further inhibiting the occurrence of inflammation. In addition to this anti-inflammatory effect, flavonoids and alkaloids can scavenge free radicals, that is, they can delay facial aging; further, flavonoids can also slow down the formation of melanin and absorb ultraviolet rays, playing a whitening role.

[0023] Introducing an appropriate amount of linoleic acid into the facial mask liquid can play an antibacterial, whitening, and antioxidant role, forming a barrier on the skin to protect the skin from dehydration, allergens, and bacteria. However, considering that different skin types have different receptive abilities to linoleic acid, too much linoleic acid can also cause skin inflammation, allergies, and other problems, so it is also necessary to supplement it with anti-inflammatory substances to work with it. Based on this, the inventor thought that in addition to being rich in linoleic acid, grape seeds also contain rich proanthocyanidins, and further extracted linoleic acid and proanthocyanidins from grape seeds, and hydrolyzed proanthocyanidins were hydrolyzed to obtain hydrolyzed proanthocyanidins. The synergistic effect of linoleic acid and hydrolyzed proanthocyanidins in grape seed extract can comprehensively enhance the whitening and moisturizing effects of the facial mask liquid.

[0024] In order to further effectively reduce the damage of free radicals to the skin and promote the metabolism and repair of skin cells, the scheme further adds some hydrolyzed proanthocyanidins separately and appropriately; then adds some ectoine, which has the effect of treating skin inflammation, allergic skin diseases, etc. It can be used as a special treatment drug for infant skin and is very mild. Therefore, ectoine is further added as a raw material for facial mask liquid to enhance the anti-inflammatory and anti-allergic effects of the mask. In addition, ectoine can also balance the osmotic pressure of cells, provide long-term moisturizing for the skin, increase the water content in the skin, and keep the skin moist and shiny; ectoine can also repair and soothe damaged skin, reduce wrinkles and skin roughness, enhance the immune protection ability of skin cells, and effectively prevent skin aging.

[0025] Cucumber fruit water is rich in nutrients, which can make the mask more refreshing while promoting skin moisturizing and whitening; carboxymethyl chitosan and sodium hyaluronate have excellent moisturizing effects, and work synergistically with cucumber fruit water and tetrahydromethylpyrimidine carboxylic acid to moisturize the skin and promote the absorption of effective ingredients in the mask liquid. In addition, carboxymethyl chitosan also has a certain bactericidal effect, which enhances the shelf life of the mask liquid.

[0026] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention prepares a refreshing, anti-inflammatory, anti-allergic and whitening and repairing facial mask. The facial mask contains the main ingredients of physalis extract, grape seed extract, hydrolyzed proanthocyanidins, and tetrahydromethylpyrimidine carboxylic acid, all of which can play an anti-inflammatory and anti-allergic role, and because all four are skin-friendly raw materials, they are mild and non-irritating to the skin. Under the synergistic effect of the four, the facial mask exhibits excellent anti-inflammatory and anti-allergic effects; at the same time, all four have excellent antioxidant properties, so they can also repair damaged skin and improve skin condition, so they can remove facial skin free radicals and promote skin repair and whitening. In summary, the facial mask prepared by the present invention not only meets the basic whitening, moisturizing, and anti-aging effects, but also has anti-inflammatory and anti-allergic effects, which can greatly fill the market gap and is in line with market demand.
