Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a water-free and thickener-free facial mask liquid composition and a preparation method thereof. Background Art

[0002] Facial mask is an important category in beauty and skin care products, and occupies a large market share in the field of skin care products. It uses natural cotton or silk cloth as a carrier, soaked in mask liquid, and each bag contains a piece of mask cloth. Because this type of product is easy to use and carry, after 15 to 30 minutes of facial application, consumers can take a short break, and can easily achieve the effects of rapid hydration, repair and brightening of skin color, so it is deeply loved by consumers.

[0003] At present, there are many kinds of facial masks on the market, and their functions are also different. Although many facial masks have the functions of whitening and moisturizing, it is difficult to achieve a long-lasting moisturizing effect from multiple angles. Often, they can only replenish moisture in time, but cannot lock in moisture for a long time. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a water-free and thickener-free facial mask liquid composition, which has good moisturizing and hydrating effects and can keep moisturizing for a long time; and the raw materials do not contain water and thickeners, the ingredients are simple, and the preparation process is simple.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The first aspect of the present invention provides a water-free and thickener-free facial mask liquid composition, which is composed of a skin conditioner, a moisturizer and an antioxidant; wherein the skin conditioner is composed of Tremella fuciformis polysaccharide fermentation liquid, Dendrobium officinale extract, Lactobacillus / North American holy grass fermentation product extract and Macrophylla macrophylla extract.

[0007] Tremella polysaccharide fermentation liquid is obtained by fermenting Tremella fruiting bodies with probiotics. It is rich in Tremella polysaccharides, proteins, fats, inorganic salts and B vitamins. Tremella polysaccharides have excellent moisturizing, water-locking functions and skin affinity. Its molecules contain a large number of hydrophilic groups such as carboxyl and hydroxyl groups, which can absorb and lock moisture and provide a lasting moisturizing effect for the skin. At the same time, the molecular structure of Tremella polysaccharides is similar to the glycoprotein on the surface of the skin, which makes it easier to be absorbed and utilized by the skin, thereby playing a deep nourishing and repairing role. In addition, Tremella polysaccharides also have good antioxidant and anti-inflammatory effects, which can remove free radicals in the skin, reduce the damage of oxidative stress to the skin, and slow down cell aging; it can also inhibit inflammatory reactions, relieve skin sensitivity and redness and swelling; it can also promote the synthesis of collagen, increase skin elasticity, and keep the skin smooth and delicate. After fermentation, the biological activity of Tremella polysaccharides can be improved, making the active ingredients in the fermentation liquid easier to be absorbed by the skin, so that it performs better in moisturizing, anti-oxidation, anti-inflammatory, repair and other functions.

[0008] Dendrobium officinale extract is rich in active substances such as polysaccharides, polyphenols, flavonoids, alkaloids, amino acids, etc. The main active ingredients are polysaccharides, which contain a large number of hydrophilic hydroxyl groups, which can form a biofilm on the skin surface, slow down the evaporation of water in the stratum corneum, and produce moisturizing and skin barrier repair effects on the skin surface; the phenolic hydroxyl structure of polyphenols has strong reducing properties and is a natural antioxidant that can reduce the problems caused by oxidative damage to the skin; flavonoids can inhibit the activity of tyrosinase and reduce the formation of melanin; alkaloids can inhibit inflammatory factors and relieve inflammatory reactions; amino acids and other ingredients can reduce the damage to the skin caused by external stimuli and improve the skin's resistance.

[0009] Lactobacillus / Sacred Grass Ferment Extract is a natural ingredient extracted from Lactobacillus and Sacred Grass. It has excellent moisturizing and antioxidant properties. It can help fight free radicals and prevent environmental damage to the skin; it can help the skin lock in moisture and keep the skin hydrated; it can relieve skin inflammation and sensitive reactions and reduce discomfort.

[0010] The extract of giant algae is rich in algin, vitamins, amino acids and other ingredients. Algin is a natural moisturizing and softening agent that can promote cell regeneration, strengthen skin metabolism, renew the skin and prevent wrinkles.

[0011] The facial mask liquid composition of the present invention uses a variety of plant extracts and biological fermentation products as skin conditioners. By utilizing their unique biological activities and taking advantage of their strengths to make up for their weaknesses, the composition has multiple functions such as good moisturizing, soothing, anti-aging, anti-oxidation and whitening, and can produce a long-lasting moisturizing effect; it can increase skin elasticity and reduce skin wrinkles; at the same time, it is highly safe, mild and non-irritating.

[0012] Furthermore, the anhydrous and thickener-free facial mask liquid composition is composed of the following components by mass fraction: 0.2-1% of Dendrobium officinale extract, 0.1-1% of Lactobacillus / North American holy grass fermentation product extract, 0.1-0.5% of giant algae extract, 5-18% of moisturizer, 0.3-0.6% of antioxidant, and the remainder of Tremella polysaccharide fermentation liquid.

[0013] Furthermore, the Tremella polysaccharide fermentation broth is prepared by the following method:

[0014] S1. Crush the Tremella fuciformis fruiting body, add water in a mass ratio of 1:(10-30), boil and keep for 20-50 min; after cooling, add a sugar source, stir until completely dissolved, and obtain a mixture;

[0015] S2. The mixture of step S1 is sequentially ground and homogenized by a colloid mill and a homogenizer to obtain a slurry; and then the pH of the slurry is adjusted to 2.8 to 3.5 to obtain a fermentation substrate;

[0016] S3. Inoculate the composite probiotics into the fermentation matrix of step S2, seal it, ferment it at 28-35° C. for 12-48 hours, and obtain Tremella polysaccharide fermentation liquid after filtering.

[0017] Furthermore, in the above step S1, the sugar source includes at least one of sucrose and glucose.

[0018] Further, in the above step S3, the composite probiotics are composed of Lactobacillus plantarum, Saccharomyces cerevisiae and Lactobacillus bulgaricus, and their mass ratio is 1:(1-3):(1-3). When Lactobacillus plantarum, Saccharomyces cerevisiae and Lactobacillus bulgaricus are used for composite fermentation, a rich enzyme system can be produced to fully enzymatically destroy the Tremella cell wall, thereby promoting the dissolution of effective ingredients in the Tremella cells, and therefore helping to improve the yield of the product.

[0019] Further preferably, the composite probiotics consists of Lactobacillus plantarum, Saccharomyces cerevisiae and Lactobacillus bulgaricus, and their mass ratio is 1:1:1.

[0020] Further, the moisturizing agent includes at least one of butylene glycol, 1,2-hexanediol, sodium hyaluronate, and glycerol;

[0021] The antioxidant includes at least one of p-hydroxyacetophenone, phenoxyethanol, methylparaben and propylparaben.

[0022] Furthermore, the viscosity of the facial mask liquid composition ranges from 800 to 1500 mPa·s.

[0023] Compared with the Tremella polysaccharide obtained by other methods, the Tremella polysaccharide fermentation liquid has both high molecular weight Tremella polysaccharide (weight average molecular weight of 3 million to 5 million Daltons) and low molecular weight Tremella polysaccharide (weight average molecular weight of 100,000 to 300,000 Daltons). The complex network structure in the high molecular weight Tremella polysaccharide improves the viscosity, so that the Tremella polysaccharide fermentation liquid has a higher viscosity. The inventors use the Tremella polysaccharide fermentation liquid to have certain solubility and high viscosity characteristics, creatively remove the solvent and thickener components in the conventional mask liquid, by increasing the proportion of Tremella polysaccharide fermentation liquid in the mask liquid, and replacing the solvent and thickener with Tremella polysaccharide fermentation liquid, thereby obtaining a mask liquid with simple ingredients, outstanding efficacy, and no water and thickener. The mask liquid without water and thickener not only simplifies the preparation process, but also has lower cost. In addition, the high molecular weight Tremella polysaccharide can more easily form a tough and transparent film on the skin surface, which can protect the skin and prevent the loss of moisture.

[0024] Low molecular weight tremella polysaccharide has higher bioavailability and can more easily penetrate the skin surface and penetrate deep into the skin, thus improving dry and dehydrated skin problems from the root. Secondly, low molecular weight tremella polysaccharide has better antioxidant properties and can inhibit the production of free radicals and cellular oxidation reactions, slow down the skin aging process, and protect the skin from damage by the external environment and ultraviolet rays. In addition, low molecular weight tremella polysaccharide has excellent refreshing and non-greasy properties, making the mask liquid feel better on the skin.

[0025] Furthermore, the anhydrous and thickener-free facial mask liquid composition is composed of the following components by mass fraction: 0.2-1% of Dendrobium officinale extract, 0.1-1% of Lactobacillus / North American holy grass fermentation product extract, 0.1-0.5% of Sargassum extract, 5-15% of butylene glycol, 0.1-0.3% of sodium hyaluronate, 0.3-1.5% of 1,2-hexanediol, 0.3-0.6% of p-hydroxyacetophenone, and the remainder of Tremella polysaccharide fermentation liquid.

[0026] Furthermore, the anhydrous and thickener-free facial mask liquid composition is composed of the following components by mass fraction: 0.5% of Dendrobium officinale extract, 0.8% of Lactobacillus / North American holy grass fermentation product extract, 0.3% of giant algae extract, 10% of butylene glycol, 0.2% of sodium hyaluronate, 0.8% of 1,2-hexanediol, 0.5% of p-hydroxyacetophenone, and 86.9% of Tremella polysaccharide fermentation liquid.

[0027] The second aspect of the present invention provides a method for preparing a water-free and thickener-free facial mask liquid composition, comprising the following steps:

[0028] S1. Add skin conditioner, moisturizer and antioxidant into an emulsifier, heat to 80-85°C, stir at 500-1000 rpm until completely dissolved without particles; then homogenize at 1000-3000 rpm for 3-5 minutes, keep constant temperature at 80-85°C for 10-30 minutes and then cool down;

[0029] S2. Cooling to below 40° C., filtering the material to obtain the anhydrous and thickener-free facial mask liquid composition.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The water-free and thickener-free facial mask liquid composition provided by the present invention has multiple functions such as good moisturizing, soothing, anti-aging, anti-oxidation and whitening, and can produce a long-lasting moisturizing effect; it can increase skin elasticity and reduce skin wrinkles; at the same time, it is highly safe, mild and non-irritating.

[0032] 2. The water-free and thickener-free facial mask liquid composition provided by the present invention uses Tremella polysaccharide fermentation liquid instead of solvent and thickener, which not only simplifies the composition and preparation process of the facial mask liquid, but also reduces the cost and has outstanding efficacy.

[0057] The formulas of the facial mask liquid compositions of Examples 1 to 3 and Comparative Examples 1 to 5 are shown in Table 1.

[0058] Table 1

[0059]

[0060]

[0061] Efficacy testing

[0062] 80 female volunteers aged 25 to 35 were selected and randomly divided into 8 groups, with 10 people in each group. Each group of volunteers used the facial mask liquid samples of Examples 1 to 3 and Comparative Examples 1 to 5 respectively. The method of use was as follows: after the volunteers cleaned their faces, they took an appropriate amount of the facial mask liquid composition of Examples 1 to 3 and Comparative Examples 1 to 5, soaked the facial mask cloth and applied it to the face. After 15 minutes, the facial mask cloth was removed, and the moisture content of the facial skin was measured using a skin moisture meter at 0h, 1h, 3h and 6h of use. The test results were averaged, and the results are shown in Table 2 below.

[0063] Table 2

[0064] After using 0h After 1 hour of use After 3 hours of use After 6 hours of use Example 1 73.1％ 65.3％ 55.9％ 51.1％ Example 2 72.4％ 65.1％ 54.3％ 49.8％ Example 3 73.2％ 66.0％ 55.5％ 50.8％ Comparative Example 1 70.2％ 61.3％ 48.7％ 40.5％ Comparative Example 2 68.8％ 55.2％ 43.6％ 35.0％ Comparative Example 3 72.5％ 63.4％ 51.8％ 46.9％ Comparative Example 4 72.4％ 62.6％ 50.4％ 47.0％ Comparative Example 5 73.1％ 62.1％ 49.8％ 46.5％

[0065] Please refer to Table 2. The facial mask compositions of Examples 1 to 3 not only have a good moisturizing effect, but also have excellent moisturizing and water-locking functions. After 0 hours of use, the water content of the skin is above 72%, and after 6 hours of use, the water content of the skin can still be maintained at 50% or above.

[0066] The mask composition of Comparative Example 2 does not contain Tremella polysaccharide fermentation liquid, and its hydration and moisturizing effects are greatly reduced, and the skin moisture content after 0h is less than 70%, and the skin moisture content after 6h is only 35%. Since Tremella polysaccharide fermentation liquid has rich Tremella polysaccharide, after biological fermentation, the fermentation liquid contains high-molecular-weight Tremella polysaccharide and low-molecular-weight Tremella polysaccharide at the same time, wherein the low-molecular-weight Tremella polysaccharide has high bioavailability, and it is easier to penetrate the skin surface, penetrate into the skin, and improve the skin dryness and water shortage problems from the root, thereby achieving better hydration effect; and high-molecular-weight Tremella polysaccharide can form a tough and transparent film on the skin surface, which can protect the skin and prevent the loss of water; in addition, the molecular structure of Tremella polysaccharide itself makes it have good affinity, can absorb and lock water, thereby providing a lasting moisturizing effect for the skin.

[0067] The mask composition of Comparative Example 1 uses commercially available Tremella polysaccharide powder instead of Tremella polysaccharide fermentation liquid. From the results, its hydrating and moisturizing effects are not as good as those of Examples 1 to 3. This is because the Tremella polysaccharide in the biologically fermented Tremella polysaccharide fermentation liquid has higher activity, better bioavailability, and is more easily absorbed by the skin; and the Tremella polysaccharide fermentation liquid also contains rich protein, fat, minerals, vitamins, probiotics and other ingredients, has better repair effect, can promote the formation of skin barrier, and further improves the skin's water-locking and moisturizing effect.

[0068] In the mask compositions of Comparative Examples 3 to 5, the extract of Dendrobium officinale, the extract of Lactobacillus / Herba sacchariflora fermentation product and the extract of Macrophylla sutchuenensis were removed respectively on the basis of Example 1. From the results, the moisturizing effect thereof decreased to a certain extent. The three ingredients of Dendrobium officinale extract, Lactobacillus / Herba sacchariflora fermentation product extract and Macrophylla sutchuenensis extract can improve the hydration and moisturizing effects through different mechanisms. When used together, they can form a synergistic effect in hydration and moisturizing, so that the mask liquid can obtain a long-lasting moisturizing effect.

[0069] In summary, the water-free thickener-free facial mask liquid composition provided by the present invention has multiple functions such as good moisturizing, soothing, anti-aging, anti-oxidation and whitening, and can produce a long-lasting moisturizing effect; it can increase skin elasticity and reduce skin wrinkles; at the same time, it is highly safe, mild and non-irritating; and, the facial mask liquid composition uses Tremella polysaccharide fermentation liquid instead of solvents and thickeners, which not only simplifies the ingredients and preparation process of the facial mask liquid, but also has lower costs and outstanding efficacy.

[0070] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
