Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a facial mask with moisturizing effect and a preparation method thereof. Background Art

[0002] Facial masks can be classified by texture. Most moisturizing masks sold on the market are made of essence and mask cloth. The essence is attached to the skin with the help of the mask cloth, allowing the skin to be immersed in the moisturizing essence. This type of mask is convenient to carry and use. The disadvantage is that the material and shape of the mask cloth and the fit of the user's face may affect the absorption of the essence, and the essence is easy to evaporate on the surface of the mask cloth. Mud masks have good adsorption properties and can absorb dirt, excess oil and aging skin keratin on the skin surface. The disadvantage is that the skin dries faster after use and the moisturizing performance is low. Most of the mud masks in the prior art only solve the performance problem and ignore the problem of dry skin after use.

[0003] In order to make up for the defect of insufficient moisturizing performance of mud mask, some high-efficiency moisturizing ingredients can be added to the mud mask formula, such as sodium hyaluronate, which can capture and lock a large number of water molecules, replenish moisture to the skin while cleaning the skin, and reduce the dryness that may be caused by the strong cleansing power of the mud mask; some components that improve functionality can also be added to give new functions, such as whitening and anti-aging. If too many functional components are added to enhance fluidity, it may lead to new problems such as difficulty in forming or slow drying of the mask. To solve this problem: on the one hand, the formula ratio can be optimized, the amount of mud matrix and fluid components added can be accurately calculated, and the balance point that can ensure both the formation of the mask and the improvement of moisturizing performance can be found through multiple tests; on the other hand, auxiliary ingredients with thickening or gelling effects can be selected to ensure that the viscosity and stability of the system are increased without affecting the overall moisturizing performance, so that the mask can maintain a good texture while evenly dispersing the components with strong fluidity, avoiding the flow, non-forming or slow drying during actual use, which affects the use, and ensuring that the components are fully mixed and interact stably, thereby ensuring the overall use effect and experience of the mask.

[0004] CN101181190A discloses a facial mask cosmetic for removing red blood streaks, wherein two additive components, skin cell epidermal growth factor (BFGF) and vitamin E, are added to the formula. Cell epidermal growth factor (BFGF) has the effect of removing wrinkles and removing spots, and vitamin E can increase the blood flow of skin capillaries and maintain the normal permeability of capillaries. Adding both to the facial mask base material can play the role of removing facial red blood streaks, moisturizing, skin care and beautifying.

[0005] CN105362160A discloses a mud mask containing Chinese herbal medicine extracts and a preparation method thereof. The invention uses green stone mud, montmorillonite and kaolin as the base materials of the mud mask, which has excellent cleaning and adsorption effects; the addition of allantoin can promote skin cell production, relieve inflammation; at the same time, the addition of Stephania tetrandra extract and Portulaca oleracea extract has good anti-inflammatory, anti-allergic and acne-removing effects.

[0006] The solutions reported in the above patent documents only solve the performance problem but ignore the problem of skin dryness after use. Summary of the invention

[0007] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to solve the problem of skin drying easily after using a mud mask, while not affecting the molding speed of the mask, which is more in line with actual usage.

[0008] To achieve the above object, the present invention provides a facial mask with moisturizing effect and a preparation method thereof.

[0009] A method for preparing a facial mask with moisturizing effect, characterized in that it comprises the following steps, calculated by mass percentage:

[0010] (1) adding 1-2 wt% guar gum and 2-3 wt% sodium hyaluronate to 15-25 wt% water and stirring for 1 hour, adding 0.1-0.2 wt% disodium ethylenediaminetetraacetate and 0.8-1.2 wt% moisturizer, and stirring at 60-80° C. for 0.5-1 hour to obtain component A;

[0011] (2) adding 0.4-0.6 wt% of the extract, 0.2-0.6 wt% of squalane, and 0.4-0.8 wt% of hydroxyethyl cellulose to 6-8 wt% of water and stirring at room temperature for 0.5-1 hour as component B;

[0012] (3) 15-35 wt% of green stone mud, 1-3 wt% of almond oil, and 1-3 wt% of propylene glycol are added to 15-35 wt% of water and stirred at room temperature for 1 hour to prepare component C;

[0013] (4) Components A, B, and C were mixed and stirred for 1 hour, and water was added to make up to 100 wt % to obtain the facial mask with moisturizing effect.

[0014] In the step (1), the moisturizing agent is one or more of fish skin collagen peptide, maltodextrin, and fish skin collagen peptide-maltodextrin microspheres; preferably, the moisturizing agent is fish skin collagen peptide-maltodextrin microspheres.

[0015] The preparation method of the fish skin collagen peptide-maltodextrin microspheres is as follows:

[0016] The fish skin collagen peptide was added to the maltodextrin-water solution, stirred at room temperature for 0.5 hours, and sent to a spray dryer for drying to obtain fish skin collagen peptide-maltodextrin microspheres.

[0017] The weight ratio of the fish skin collagen peptide to the maltodextrin-water solution is 0.8-1.2:25-35.

[0018] The concentration of the maltodextrin-water solution is 5-15wt% of the maltodextrin-water solution.

[0019] The extract in step (2) is one or more of Chondrus crispus extract, Centella asiatica extract, Amaranthus spinulosa extract, Matricaria recutita extract, and Opuntia contorta stem extract.

[0020] The facial mask with moisturizing effect of the present invention is composed of components A, B, C and water, wherein component A includes guar gum, sodium hyaluronate, disodium edetate, and moisturizer, component B includes extract, squalane, hydroxyethyl cellulose, and component C includes green stone mud, almond oil, and propylene glycol. Guar gum and sodium hyaluronate in component A form a viscous gel solution in water, wherein guar gum can increase the viscosity of the entire facial mask, so that the facial mask can be better attached to the skin surface when applied, and is not easy to flow, thereby contributing to the formation of the facial mask. The molecular structure of sodium hyaluronate contains a large amount of carboxyl and hydroxyl groups, which can be closely combined with water molecules through hydrogen bonds, and can form a dense and elastic moisturizing film on the skin surface, which can not only prevent the evaporation of water in the skin, but also maintain the moisture of the skin, and can also continuously provide moisture to the skin, so that the skin is in a hydrated state for a long time, effectively solving the problem that the mud-like facial mask is easy to dry after use. Disodium edetate component A plays a role in improving the stability of the gel solution, and ensures the stability of the entire formula system in the facial mask. As a moisturizer, maltodextrin itself has good water absorption and moisturizing properties. The multiple glucose units in its molecular structure can attract and lock moisture, increase the water content of the skin, and thus enhance the moisturizing effect of the mask. As a moisturizer, fish skin collagen peptide can penetrate into the surface of the skin, combine with the water binding sites in the skin cells, enhance the hydration of skin cells, improve the water retention capacity of the skin, and make the skin firmer and more elastic; it can also promote the metabolism of skin cells, help damaged skin, and improve the overall condition of the skin. Fish skin collagen peptide-maltodextrin microspheres increase the specific surface area by combining fish skin collagen peptide with maltodextrin to form a microsphere structure, and use the structure of maltodextrin to provide certain support and wrapping effects, and wrap the small molecule peptide fish skin collagen peptide in it. During the use of the mask, the fish skin collagen peptide is slowly released to continuously provide moisturizing effect to the skin.

[0021] The extracts added to component B include one or more of Chondrus crispus extract, Centella asiatica extract, Amaranthus spinulosa extract, Golden chamomile extract, and Prickly Pear cactus stem extract. The extract components can cooperate with each other to synergistically play a role in skin care. Chondrus crispus extract is rich in a variety of hydrophilic polysaccharides, which can create a moist environment for skin recovery, enhance the vitality of skin cells, promote cell metabolism, and help the recovery and regeneration of damaged skin cells. Its mild nature can also soothe the irritation of the skin, reduce the inflammatory response of the skin, and has a positive significance for improving the sensitive state of the skin. The asiaticoside in the Centella asiatica extract can enhance the elasticity of the skin, reduce the formation of wrinkles, make the skin firmer, and also help the recovery of damaged skin. Amaranthus spinulosa extract contains a variety of alkaloids and flavonoids, which can prevent and improve skin problems caused by bacterial infections, such as acne, blackheads, etc., while reducing the oxidative damage of free radicals to skin cells, delaying skin aging, and promoting the recovery and regeneration of skin cells. The main active ingredient of golden chamomile extract is flavonoids, which can neutralize free radicals, protect skin cells from oxidative stress, prevent skin aging, and restore the skin to a healthy balance. The extract of twisted prickly cactus stem is rich in various nutrients, which can enhance the skin's own resistance, promote the recovery and regeneration of skin cells, help improve the skin's self-recovery ability, and enable the skin to recover faster when facing external stimuli. Squalane in component B can enhance the skin's barrier function, maintain the skin's moisture balance, and keep the skin healthy. Hydroxyethyl cellulose mainly plays the role of adjusting the texture in the mask, making the mask more uniform and delicate, easy to apply and use, and better play the moisturizing effect.

[0022] The green stone mud in component C has a strong adsorption capacity, can absorb dirt, oil and aged keratinocytes on the skin surface, clean pores, and make the skin more refreshing and clean. It is added to the preparation of the mask as the main component of the mask of the present invention to obtain a mud-like form. Almond oil is rich in nutrients such as unsaturated fatty acids and vitamins, has a good moisturizing effect, and mainly plays a lubricating role in component C. Propylene glycol also has moisturizing and nourishing effects, can increase the water content of the stratum corneum and improve skin permeability.

[0023] Beneficial effects of the present invention:

[0024] Compared with the prior art, the facial mask with moisturizing effect of the present invention is composed of components A, B, C and water, component A includes guar gum, sodium hyaluronate, disodium ethylenediaminetetraacetic acid, moisturizer, component B includes extract, squalane, hydroxyethyl cellulose, component C includes green stone mud, almond oil, propylene glycol, and the moisturizing effect is improved by the interaction of each component, and the problem of easy drying of the skin after the mud mask is used is solved without affecting the molding speed of the mask, which is more in line with the actual use situation. The present invention uses component C as the main raw material of the facial mask, determines that the texture of the facial mask is mud-like, and in terms of moisturizing effect, by adding moisturizer to the gel solution formed by sodium hyaluronate and maltodextrin, the problem of easy drying of the skin after the facial mask is used is effectively solved, so that the skin can be kept moist for a long time; in terms of skin care, the synergistic effect of multiple extracts in component B improves damaged skin from multiple aspects such as promoting cell regeneration, enhancing elasticity, antibacterial and anti-inflammatory, and anti-oxidation, and improves the overall health of the skin.

[0068] Test Example 1

[0069] The facial mask with moisturizing effect obtained by the preparation method of Examples 1-4 was tested for water loss rate. Three test mice were set for parallel tests in each example, and the weight of the test mice was between 20-25g. Before the test, the mice were anesthetized by breathing with isoflurane, and then the hair on the back of the mice was shaved off. After disinfection with alcohol, they were left to stand for 10 minutes in an environment of 25°C and 50% humidity; a test circle with a diameter of 20mm was circled on the back skin of the mice, and 0.5g of the facial mask sample was taken and spread in the test circle, and the mice were placed on an electronic balance; the actual application time of the facial mask of the present invention was 10 minutes, and 0.05g of the facial mask sample was taken out at 0, 2, 4, 6, 8, and 10 minutes for moisture testing and recording, and the moisture reduction of the facial mask sample before and after was compared with that at 0 minutes to obtain the water loss rate of the facial mask of this embodiment in this time period; the test data was averaged and summarized as shown in Table 1.

[0070] Table 1 Water loss rate test

[0071] 2min 4min 6min 8min 10min Example 1 3.5％ 6.7％ 9.1％ 10.5％ 12.0％ Example 2 7.1％ 9.8％ 12.4％ 14.2％ 15.8％ Example 3 10.4％ 13.6％ 16.4％ 19.0％ 20.8％ Example 4 13.0％ 16.2％ 19.4％ 22.1％ 24.8％

[0072] In Test Example 1, Examples 1-4 were placed together in an environment of 25°C, and the test was carried out under the condition that the water evaporation rate in the environment was consistent. In Example 1, no moisturizer was added, and it was difficult for the mask to form an effective moisturizing barrier on the mouse skin simulating human skin. The water loss rate within the initial 2 minutes was only 3.5%. It was difficult to lock in moisture when absorbing the moisture of the mask. The slow water loss was not conducive to the formation of the mask texture. Compared with Examples 2-4, the water loss rate was lower. In Examples 2-3, maltodextrin and fish skin collagen peptide were added as moisturizers, respectively. Maltodextrin has good water absorption and moisturizing properties. It can form a moisturizing film on the surface of mouse skin, attract and lock moisture, and increase the water loss rate of the mask. The water loss rate within 2 minutes is 7.1%, which is significantly improved compared with Example 1. As time goes by, the water loss rate is greater than 10% at 6 minutes, and the mask is basically formed. In Example 3, fish skin collagen peptide is added as a moisturizer. Fish skin collagen peptide can penetrate into the surface layer of mouse skin, replenish skin moisture, and enhance the skin's water retention capacity, so that the water loss rate in the mask is further increased. The water loss rate within 2 minutes is 10.4%, ensuring that the mask is basically formed.

[0073] Example 4 added the prepared fish skin collagen peptide-maltodextrin microspheres. Maltodextrin is a polysaccharide substance composed of multiple glucose units connected by glycosidic bonds, and its molecular chain presents a certain branching structure. This branching structure gives it a larger spatial volume. The fish skin collagen peptide is combined with maltodextrin to form a microsphere structure. The spray drying process makes the microspheres loose and porous, greatly increasing the specific surface area; when added to the facial mask of the present invention, its loose and porous structure can quickly absorb and store a large amount of moisture, and the increase in specific surface area makes the contact between the microspheres and the mouse skin more sufficient and close, and the fish skin collagen peptides in the microspheres can rely on their smaller molecular structure advantages to penetrate the stratum corneum of the skin and penetrate into the Inside the skin, it combines with the water binding sites in the skin cells to enhance the hydration of the skin cells, replenish skin moisture, and enhance the skin's water retention capacity from the inside; at the same time, the hydroxyl groups on the maltodextrin molecular chain form hydrogen bonds with the moisture on the skin surface, forming a stable moisturizing film on the skin surface, preventing the moisture inside the skin from dissipating outward, and continuously releasing moisture from the microspheres to the skin surface, maintaining a moist environment on the skin surface, making it easier for mouse skin to absorb and lock in moisture, thereby improving the skin's moisturizing effect while affecting the water loss rate of the mask, which helps the mask to take shape quickly. Within 2 minutes, the water loss rate was 13.0%, and the mask was basically formed, solving the problem of difficulty in forming a mud mask due to the addition of functional components such as moisturizing.

[0074] Test Example 2

[0075] 20 female subjects aged between 20 and 30 were selected and divided into 2 groups, and the moisturizing rate of the facial masks of Example 4 and Comparative Example 1 was tested. Before the test, the subjects were required to wait for 0.5 h in an environment of 20°C and 40% humidity, and no other moisturizing products were allowed to be used during the test; the 2 groups of subjects were respectively smeared with the facial masks with moisturizing effect of Example 4 and Comparative Example 1, and the thickness of the facial masks on the face was 1 mm, and they were kept for 10 minutes and then cleaned, and the timing was started; the moisture content of the skin cheeks was tested and read before the test and every 10 minutes using a skin moisture tester, and the test was stopped after 30 minutes; the test data were averaged and summarized as shown in Table 2.

[0076] Table 2 Moisture retention test

[0077] Before the test 10min 20min 30min Example 4 34.0％ 50.4％ 46.9％ 44.5％ Comparative Example 1 34.5％ 45.4％ 37.6％ 36.3％

[0078] In Test Example 2, the moisturizing properties of the facial masks of Example 4 and Comparative Example 1 were tested. The difference between the two is that in component A of Example 4, fish skin collagen peptide-maltodextrin microsphere moisturizer is added to the gel solution containing guar gum and sodium hyaluronate. Guar gum itself has a certain thickening and water-retaining effect, which helps to increase the viscosity of the facial mask, so that the facial mask can better adhere to the skin surface, reduce water loss, and thus improve moisturizing properties; sodium hyaluronate contains a large number of carboxyl and hydroxyl groups in its molecular structure, which can be tightly combined with water molecules through hydrogen bonds, can absorb a large amount of water and form a moisturizing film on the skin surface. This moisturizing film can not only prevent the loss of moisture inside the skin, but also continuously provide moisture to the skin to keep the skin moist; at the same time, the fish skin collagen peptide-maltodextrin microsphere moisturizer itself has good moisturizing properties, can penetrate into the bottom layer of the skin, replenish moisture and nutrition to the skin, promote the metabolism of skin cells, and enhance the skin's water retention capacity.

[0079] In Comparative Example 1, component A only adds fish skin collagen peptide-maltodextrin microsphere moisturizer to water, and no gel solution is formed. The thickening and water-retaining effects of guar gum and the efficient moisturizing film formed by sodium hyaluronate are lacking, resulting in poor adhesion of the mask on the skin surface, easy loss of moisture, and failure to continuously provide moisture to the skin and lock moisture like Example 4. Therefore, during the test, its moisturizing rate is significantly lower than that of Example 4, and the skin moisture content gradually decreases with the passage of time; the facial skin moisture content of the subjects in Example 4 can reach 50.4% at 10 minutes after the end of use. Without the use of other moisturizing products, the moisture will evaporate naturally over time. At 30 minutes, the moisture content still reaches 44.5%, which is much higher than that of Comparative Example 1, fully demonstrating the moisturizing advantage of the moisturizing mask in Example 4.

[0080] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
