Description

Technical Field

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

[0002] The outermost layer of the skin is the stratum corneum, which is like a brick wall structure. Among them, keratinocytes are "bricks" and the lipids between cells are "mortar". Under normal circumstances, the water in the skin will be lost through the stratum corneum, a process called transepidermal water loss (TEWL). When the external environment is dry or the skin barrier is damaged, the water loss will accelerate.

[0003] The main function of hydrating and moisturizing masks is to reduce this water loss and replenish moisture to the skin. They do this by forming a protective film on the surface of the skin, slowing down the rate of water evaporation, while delivering water and some moisturizing ingredients to the stratum corneum of the skin.

[0004] Patent CN106265334B provides a hydrating and moisturizing Chinese medicine mask, which mainly enhances the skin's hydrating and moisturizing ability through 1-3 parts of Atractylodes macrocephala, 0.5-2 parts of Ganoderma lucidum polysaccharide, 2-4 parts of aloe vera, 1-3 parts of wolfberry, 2-3 parts of Polygonatum odoratum, 1-2 parts of Coix seed powder, 1-3 parts of Salvia miltiorrhiza, etc., to achieve the effects of moisturizing the skin and improving skin quality. The moisturizing effect of the moisturizer in the prior art is not long-term, and can only play a moisturizing effect in a short period of time, and the long-term moisturizing effect is significantly reduced. Summary of the invention

[0005] The purpose of the present invention is to provide a sodium hyaluronate hydrating and moisturizing facial mask and a preparation method thereof, which can significantly improve the phenomenon of dry skin and water deficiency and enhance the skin's hydrating and moisturizing ability through the synergistic hydrolysis of sodium hyaluronate and moisturizing ingredients.

[0016] Sodium hyaluronate is the sodium salt form of hyaluronic acid (hyaluronic acid). Hyaluronic acid is a macromolecular acidic mucopolysaccharide composed of repeated disaccharide units of D-glucuronic acid and N-acetylglucosamine. Sodium hyaluronate is a white fibrous or powdery solid with strong hygroscopicity. Its molecular chain contains a large number of carboxyl and hydroxyl groups, which enable it to form hydrogen bonds with water molecules, thus having good water solubility and moisturizing properties. It is a natural moisturizing factor. It can absorb and retain a large amount of water, and theoretically can absorb 1000 times its own weight in water. When it is applied to the skin surface, such as in skin care products (such as hydrating and moisturizing masks), sodium hyaluronate molecules will form a water-rich film in the stratum corneum of the skin. This film can reduce the evaporation of water on the skin surface, lock the water in the skin, and keep the skin hydrated.

[0017] Compared with the prior art, the advantages and beneficial effects of the present invention are: The invention is based on sodium hyaluronate and hydrolyzed sodium hyaluronate, and simultaneously adds ingredients such as Imperata cylindrica root extract, yeast lysate, Chondrus crispus extract, ethylhexylglycerin, isononanoate, 1,2-hexanediol, glycerin, caprylyl glycol, disodium succinate, lecithin and butylene glycol. On the one hand, the invention absorbs moisture from the surrounding environment through dilution and retains it on the skin surface, so that the skin stratum corneum is kept moist and the skin is prevented from drying out. On the other hand, a closed oil film is formed on the skin surface to prevent the moisture in the skin from radiating outwards, thereby achieving a strong moisturizing and moisturizing effect. At the same time, under the effects of betaine, peony root extract, hydrolyzed collagen and the like, the anti-inflammatory and antioxidant abilities are improved; under the synergistic effects of a-arbutin, niacinamide, 3-o-ethyl ascorbic acid and glycyrrhetinic acid, the whitening ability is enhanced; under the synergistic effects of acetyl hexapeptide-8, acetyl octapeptide-3, acetyl heptapeptide-4, palmitoyl tripeptide-5 and acetyl tetrapeptide-2, the invention has a firming and anti-wrinkle effect.

[0023] Comparative Example 1 The difference between this comparative example and Example 1 is that the hydrating and moisturizing agent in step S1 lacks Imperata root extract and yeast lysate, and the other steps are the same.

[0024] Comparative Example 2 The difference between this comparative example and Example 1 is that the hydrating moisturizer in step S1 lacks yeast lysate and Chondrus crispus extract, and the other steps are the same.

[0025] Comparative Example 3 The difference between this comparative example and Example 1 is that the anti-inflammatory agent in step S1 lacks the peony root extract and the lactobacillus / soybean fermentation product extract, and the other steps are the same.

[0026] Comparative Example 4 The difference between this comparative example and Example 1 is that the anti-inflammatory agent in step S1 lacks the peony root extract and the ginkgo biloba leaf extract, and the other steps are the same.

[0027] Comparative Example 5 The difference between this comparative example and Example 1 is that a.arbutin and nicotinamide are missing in step S1, and the other steps are the same.

[0028] Comparative Example 6 The difference between this comparative example and Example 1 is that amino acid is missing in step S4, and the other steps are the same.

[0029] Performance Test: 90 testers, females aged 18-27 years old, were selected and randomly divided into 9 groups, 10 people in each group, and tried the hydrating and moisturizing masks prepared in Examples 1-3 and Comparative Examples 1-6, respectively. After the testers cleaned their faces, they tried the masks. After the masks were applied for 15 minutes, the skin moisture content was tested before application, 2h after application, 4h after application, and 8h after application, respectively. The skin moisture content was tested using a skin moisture tester. The test results are shown in Table 1.

[0030]

[0031] It can be seen from the above performance test results that Examples 1-3 have good moisturizing and hydrating performance, and the moisturizing lasts for a long time. In particular, the comprehensive performance of Example 3 is the most outstanding. However, since Comparative Examples 1-6 do not adopt the necessary technical solutions, they are significantly worse than the Examples in the corresponding performance tests. The above experimental results further prove the importance of the technical solutions defined in the present invention for its technical effects.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
