The invention belongs to the field of cosmetics, and particularly relates to a skin-care mask liquid with multiple moisturizing effects and a preparation method thereof.

Background

With the development of social economy, the living standard of people is continuously improved, and people also pay attention to other aspects such as own facial appearance after meeting the basic requirements of clothes, eating and housing. The skin is the largest organ of the human body, is in direct contact with the external environment and is the first defense line for the body to resist external adverse factors. The healthier the skin is, the stronger the defense ability of the body against external adverse factors is, the healthy skin can also bring beautiful enjoyment to people, and brings light, pleasant, elegant and vigorous feeling to people and others. One of the important components of skin is water, which directly participates in the metabolism of skin and is closely related to the homeostasis of skin, thus supplementing water to skin and maintaining the normal metabolism of skin. Due to the influence of a series of external negative factors such as air pollution, wind and sun exposure, dry weather and the like, the skin barrier of people is easy to be damaged, and the problems of skin water shortage, dryness, roughness, peeling, red swelling, chapping and the like occur, so that the skin aging is accelerated. These skin problems are unacceptable to a large number of beauty lovers.

In order to achieve the purpose, the invention adopts the following technical scheme:

a skin-care mask liquid with multiple moisturizing effects comprises the following components in parts by weight: 4.0-8.0% of glycerin, 2.0-5.0% of butanediol, 0.1-1.0% of methylsilanol mannuronate, 0.5-2.0% of PEG-75 shea butter glyceride, 0.01-0.5% of carnosine, 1.0-5.0% of nicotinamide, 0.3-1.0% of Chondrus crispus extract, 0.1-0.3% of xanthan gum, 0.1-0.2% of carbomer, 0.04-0.06% of sodium hydroxide, 0.3-0.6% of p-hydroxyacetophenone, 0.3-0.6% of 1, 2-hexanediol, 0.1-0.2% of sodium hyaluronate, 0.01-0.1% of sodium hyaluronate acetylate, 0.2-1% of sclerotium rolfsii gum and the balance of deionized water.

Preferably, the composition comprises the following components in parts by weight: glycerin 6%, butylene glycol 3%, methylsilanol mannuronate 0.5%, PEG-75 shea butter glyceride 2%, carnosine 0.5%, nicotinamide 1%, Chondrus crispus extract 0.5%, xanthan gum 0.2%, carbomer 0.1%, sodium hydroxide 0.04%, p-hydroxyacetophenone 0.5%, 1, 2-hexanediol 0.5%, sodium hyaluronate 0.1%, sodium acetylhyaluronate 0.1%, sclerotium rolfsii gum 0.2%, and the balance of deionized water.

Wherein the butanediol is 1, 3-butanediol.

The invention also comprises a method for preparing the skin-care mask liquid with multiple moisturizing effects, which comprises the following steps:

1) the xanthan gum is stirred and dispersed in the glycerol, then deionized water and butanediol are added, the mixture is heated to 85 ℃, and the high temperature ensures that the xanthan gum is better dispersed and reduces bubbles. Starting stirring for 15 minutes to obtain a solution A;

2) cooling the solution A to 55 ℃, adding methylsilanol mannuronate, PEG-75 shea butter glyceride, carnosine, nicotinamide, Chondrus crispus extract, acetylated sodium hyaluronate, sodium hyaluronate and sclerotium rolfsii gum into the solution A, starting stirring, and uniformly stirring to obtain a solution B;

3) and adding carbomer and sodium hydroxide into the solution B, stirring at a high speed, and adjusting the pH to 6.8-7.4 to obtain a solution C.

4) Adding p-hydroxyacetophenone and 1, 2-hexanediol to the solution C. Stirring at a high speed for 100 minutes, and standing for 1 hour to obtain the mask with multiple moisturizing effects.

Compared with the prior art, the invention has the beneficial effects that:

sodium hyaluronate is generally adopted in common facial mask liquid in the prior art to form a layer of breathable film on the surface of skin, so that the loss of moisture is reduced, sodium hyaluronate and sodium acetyl hyaluronate are matched in the application, firstly, macromolecular sodium hyaluronate forms a layer of moisturizing and bright breathable film on the surface layer of the skin, micromolecular sodium acetylhyaluronate is obtained by acetylation reaction of natural moisturizing factor sodium hyaluronate, introduction of acetyl brings lipophilic property to HA, affinity and adsorbability of HA to the skin are enhanced, and the moisturizing performance of HA is improved. The acetylated sodium hyaluronate can quickly permeate the horny layer of the skin due to small molecular weight, is semi-embedded on the skin, is closely arranged in structure, can store partial water in the epidermis to hydrate the horny layer, better reduces the loss of the water, and can be firmly adsorbed on the surface of the skin due to the lipophilicity of acetyl, so that the skin is soft and elastic. Therefore, the sodium acetylhyaluronate can reduce water loss on the skin surface, increase internal water accumulation, permeate epidermis to hydrate and soften the horny layer, and act inside and outside simultaneously, thereby playing double moisturizing effects, improving the dry and rough state of the skin and enabling the skin to be soft and elastic. Figure 1 shows a schematic of HA and AcHA acting on the skin surface.

After ensuring that the moisture of the skin cannot be lost, in order to combine more moisture, the sclerotium rolfsii gum is added, a plurality of hydroxyl groups of the sclerotium rolfsii gum side chain can combine with a large amount of water molecules by utilizing hydrogen bonds, so that the water retention effect is extremely strong, meanwhile, the sclerotium rolfsii gum is of a hard triple-spiral structure formed by a hydrogen bond network, and the side chain structure faces outwards, so that the aggregation of the triple-spiral structure can be effectively avoided. And to keep moisture near the structure. Has strong water retention capacity and water replenishing capacity, can strengthen the skin barrier, and can effectively moisten dry and rough skin.

PEG-75 shea butter glyceride is water-soluble shea butter, has surface activity, and is generally used as a surfactant and an emulsifier. Experiments prove that the PEG-75 shea butter glyceride added into the moisturizing mask can not only moisturize the skin like shea butter, but also has the function of promoting the penetration of other moisturizing active substances, and can help a plurality of enzymes in carnosine, sclerotium rolfsii and carrageen crispus extracts to quickly penetrate into the skin in a large quantity. Also, PEG-75 tallowglycerides are surface active, and too much added can cause skin irritation, risk irritation, and the feel of use can be diminished, foaming on the skin.

In addition, in the extracellular matrix, polysaccharides, together with other polysaccharide components in the skin and fibrous proteins, constitute an extracellular matrix containing a large amount of moisture, providing moisture to the skin.

To solve the absorption problem, the structural integrity of the skin is required. The outermost portion that contacts and absorbs the facial mask fluid is the skin barrier, and the integrity of the skin barrier provides protection for the skin against external stimuli and for the skin to absorb actives. Natural red algae extract, Chondrus crispus extract, can improve skin barrier integrity. Chondrus crispus can promote gene expression of three key enzymes, namely SMPD3, FDPS and LASS6, in 11 enzymes for synthesizing ceramide in skin barrier protein. At low dosage, the synthesis of ceramide in epidermis can be increased by about 5 times, and the skin is full and glossy. Meanwhile, the Chondrus crispus extract can reduce the secretion of TNF-alpha induced by ultraviolet irradiation and reduce inflammatory reaction. In addition, the compound can promote the synthesis of involucrin, and the effect is better than that of vitamin D3 at the dosage of 0.1 percent. Can promote 11 key enzymes needed by skin barrier protein to synthesize ceramide, namely 3 key enzymes: 3MPD3, las 6, FDPS. Repairing skin barrier and improving water-holding capacity of skin.

The methylsilanol mannuronate is an active substance of organosilicon, is used together with sodium hyaluronate, can increase silky feeling of the product, and can prolong the drying time of the skin. Carnosine is a component present in human muscle, has a strong antioxidant aging function, and can scavenge free radicals. The skin aging problem is avoided.

In conclusion, through the synergistic effect of the parts, the skin can penetrate deeply into the skin to reduce skin inflammation and regulate the secretion of skin grease. The barrier function of the skin is enhanced to perfect the moisturizing function of the skin, and then the active matter deeply enters the skin to lock more water to enable the skin to be full, so that the moisturizing effect is achieved. Finally, a breathable moisturizing film is formed on the surface layer of the skin, so that the loss of water is reduced. The internal and external moisturizing interaction and multiple moisturizing effects act together, and finally the skin care component with multiple moisturizing effects and the facial mask thereof are prepared. The invention has stable and controllable quality, mild and non-irritant use and simple preparation process, and is suitable for large-scale development.

Stirring at a high speed for 100 minutes, and standing for 1 hour to obtain the mask with multiple moisturizing effects.

The tested population: the total 30 persons, age 30-60 years, meet the volunteer selection standard health condition of the subject.

Selecting a detected part: the area of 3cm multiplied by 3cm inside the left and right front arms is used as the detected area. The test article is randomly stuck on the inner sides of the left and right front arms.

The test conditions are below 20 plus or minus 2 ℃ at room temperature and below 50 plus or minus 5% of Relative Humidity (RH).

Instruments and reagents: one Corneometer and one hygrothermograph.

When the strength of the moisturizing effect of the moisturizing cosmetic is judged, a single application test, i.e., a moisturizing performance test, which is completed in a short time is preferably performed. The moisturizing effect can be analyzed by applying moisturizing mask liquid for 1 time in a short period and adding a water load test of the organism cuticle in the test of measuring the water content of the cuticle. The method is mainly used for determining whether the humectant has moisture retention property when selecting the humectant in the formula, and determining the optimum concentration when comparing the humectant with a matrix. Before the mask is applied, the moisture content of the stratum corneum of the part to be tested is measured. Applying the sample by using a latex finger sleeve; measuring the relative increase rate of the skin water content immediately after the test product is applied for 15min, 1h, 2h, 4h, 6h and 8 h; measuring the water content of stratum corneum of each tested part for 5 times to obtain an average value; the results of the measurements are shown in table 1 for the relative rate of increase in skin moisture content at different times.

TABLE 1

When the moisturizing ability of cosmetics is judged, the moisturizing ability is not immediately obtained. Effective moisturizing for a long time is also important for use as a cosmetic. The long-acting moisturizing effect can be analyzed by adding a water load test of the organism cuticle in the test of measuring the water content of the cuticle by using the moisturizing mask liquid for long-term application as shown in figure 2.

As can be seen from the table 1, the relative water content of the mask on the skin is obviously improved, and particularly within the time range of 0-1h after the mask is used, the moisturizing effect is reduced along with the prolonging of the time, but the relative water content of the skin within 8h within the test time range is still obviously improved and is higher than that of the skin before the mask is applied, so that the moisturizing mask solution prepared in the embodiment 3 of the invention has an obvious moisturizing effect. And relatively example 3 is much larger than example 1 and example 2. Example 1 is comparable to example 2. The difference between the method and the device is that the content of the water-soluble shea butter PEG-75 shea butter glyceride in the embodiment 3 is higher than that in the embodiments 1 and 2 and reaches 2 percent. The control group did not have the PEG-75 tallowglycerides added to increase the moisture content of the skin relatively weakly compared to the control group after the addition. In conclusion, the water-soluble shea butter is non-irritating at 2% levels and provides an increase in the performance of the active by about 52%.

And the difference between control 2 and control 3 compared to example 1 was the difference between no sodium hyaluronate and sodium acetylated hyaluronate, respectively. The moisturizing effect of example 1 was much greater than control 2 and control 3. And (4) conclusion: the matching use of 0.1 percent of sodium hyaluronate and 0.1 percent of acetylated sodium hyaluronate can improve the moisture retention rate by about 42 percent.

The results in figure 2 show that the facial mask can obviously improve the moisture content in the skin, moisten and moisturize for a long time, improve the dry state of the skin, increase the moisture content of the skin by 15 percent after being used for two weeks, and increase the moisture content of the skin by 22 percent after being used for four weeks. The same example 3 has considerable advantages over examples 1 and 2 with respect to long-term moisturization.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
