Description

Technical Field

[0001] The present invention relates to the field of cosmetics, and in particular to a water-oil compartment anti-wrinkle facial mask liquid, a preparation method thereof, and a facial mask. Background Art

[0002] Facial mask is a category of skin care products. The purpose of facial mask is to cooperate with its essence ingredients to achieve maintenance functions, such as hydrating, whitening, anti-aging and balancing oil.

[0003] One of the most obvious signs of aging is wrinkles. To enhance the anti-wrinkle effects of facial masks, people add anti-wrinkle active ingredients to the mask liquid. However, these anti-wrinkle active ingredients are less stable after mixing, easily causing discoloration and taste changes. This results in poor anti-wrinkle effectiveness of current anti-wrinkle masks, which cannot quickly resolve skin wrinkle problems. Therefore, there is room for improvement. Summary of the Invention

[0004] In order to provide a facial mask that can quickly solve the problem of skin anti-wrinkle and solve the problem of poor stability after the anti-wrinkle active substances are mixed, the present application provides a water-oil compartment anti-wrinkle facial mask liquid, a preparation method thereof and a facial mask.

[0005] A water-oil compartment anti-wrinkle facial mask liquid comprises a water compartment and an oil compartment in the following mass percentages, wherein the water compartment is as follows:

[0006] Water 74.94-88.09%

[0007] Thickener 0.1-0.3%

[0008] Moisturizer 7-16%

[0009] Antimicrobial 0.4-1%

[0010] Neutralizer 0.1-0.3%

[0011] Ulmus glabra bark extract 1.5-2.5%

[0012] Balkan Herb Leaf Extract 0.1-0.5%

[0013] Epigallocatechin Gallate Glucoside 0.03-0.08%

[0014] The oil tank is as follows:

[0015] Hydroxydecylubiquinone 0.03-0.08%

[0016] Arabica coffee seed oil 0.05-0.3%

[0017] Emollient 3-5%

[0018] Fragrance 0.01-0.05%.

[0019] In the present application, the active ingredients stored in the water tank, namely, elm wood extract, balkan chayote leaf extract, and epigallocatechin gallate glucoside, and the active ingredients stored in the oil tank, namely, hydroxydecylubiquinone and small-fruit coffee seed oil, are combined in a specific proportion to exhibit an outstanding synergistic anti-wrinkle effect, achieving safe and efficient anti-wrinkle efficacy. In addition, by storing the oil tank and the water tank separately, the poor storage stability of the mixed anti-wrinkle active substances, which is prone to discoloration and odor change, and reduced anti-wrinkle activity, is overcome. At the same time, the oily feel of the oil tank and the sticky feel of the water tank can be reduced at the same time, exhibiting a better skin feel. During use, the skin absorbs faster, the slippery feel is moderate, and there is no heavy greasy or sticky feeling.

[0020] Moreover, since the oil tank and water tank of the present application are stored separately, compared with ordinary emulsion-type facial masks, the amount of preservatives used can be reduced, which reduces irritation and prevents the mask cloth from reacting with the essence and deforming.

[0021] Preferably, the thickener is acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer.

[0022] Without adding an emulsifier, the above-mentioned facial mask liquid uses the suspension and emulsification power of acrylic acid (ester) / C10-30 alkyl acrylate cross-polymer to fully and evenly mix the smooth elm green wood, Balkan chicory leaf extract, epigallocatechin gallate glucoside stored in the water tank and hydroxydecyl ubiquinone and small-fruit coffee seed oil stored in the oil tank, maintaining the anti-wrinkle activity while reducing the irritation to the skin caused by the emulsifier, further reducing the risk of acne or skin discomfort, thereby improving the mildness and universality of the anti-wrinkle mask. After using other thickeners, the mixed dispersibility and stability of the above-mentioned anti-wrinkle active substances are significantly poor, and they cannot exert an excellent synergistic anti-wrinkle effect.

[0023] Preferably, the neutralizing agent is tromethamine.

[0024] Preferably, the moisturizing agent is one or a combination of glycerol polyether-26, glycerol and dipropylene glycol.

[0025] Preferably, the moisturizing agent comprises the following components in percentage by mass:

[0026] Glycereth-26 1-3%

[0027] Glycerol 2-5%

[0028] Dipropylene glycol 4-8%.

[0029] Glyceryl polyether-26, glycerin and dipropylene glycol are added in the above proportions, which is beneficial to improving the skin feel and moisturizing effect of the mask liquid, while opening the skin channels and promoting the penetration of anti-wrinkle active substances into the skin.

[0030] Preferably, the antibacterial agent is one or a combination of p-hydroxyacetophenone and 1,2-hexanediol.

[0031] Preferably, the emollient is one or a combination of caprylic / capric triglyceride and tocopheryl acetate.

[0032] A method for preparing a water-oil compartment facial mask liquid is prepared by the following steps:

[0033] Preparation of oil phase: Mix the ingredients except the fragrance, heat to 50-55°C, stir until completely transparent, then cool to 40-45°C, add the fragrance, stir evenly, cool and let stand to obtain the oil phase;

[0034] Preparation of the aqueous phase: Mix the moisturizer and thickener, heat to 78-88°C, stir homogeneously for at least 3 minutes, then keep warm for at least 10 minutes, cool to 42-52°C, add the remaining ingredients, stir evenly, and cool to below 40°C to obtain the aqueous phase.

[0035] The water phase and the oil phase prepared by the above method are in an appropriate ratio and can be quickly and fully mixed to ensure that the anti-wrinkle active substances are fully coordinated to obtain an excellent synergistic anti-wrinkle effect.

[0036] The invention discloses an anti-wrinkle facial mask with separate water and oil compartments, wherein the facial mask liquid and the mask cloth are stored in separate compartments, and the water compartment and the oil compartment in the facial mask liquid are also stored in separate compartments.

[0037] In summary, this application has the following beneficial effects:

[0038] 1. The present application provides a facial mask liquid that can be stored in separate compartments and can be quickly mixed and evenly mixed. By combining components such as idebenone, coffee seed oil, elm green wood extract, Balkan moss leaf extract and epigallocatechin gallate glucoside in a specific proportion and a special dosage form, it not only has an excellent skin feel, but also has an outstanding synergistic anti-wrinkle effect.

[0039] 2. No emulsifier is added to the mask liquid. Instead, the suspension and emulsification power of the water phase thickener is used to fully mix the oil phase to avoid irritation to the skin caused by the emulsifier.

[0040] 3. The mask is divided into three compartments: water, oil, and membrane. The appropriate ratio of oil to water reduces both the oily feeling in the oil compartment and the stickiness in the water compartment. This allows for faster skin absorption, a smooth feel, and no heavy, greasy or sticky sensation. Separate storage of the oil and water phases and membrane reduces the use of preservatives compared to regular lotion-based masks, reducing irritation and preventing deformation of the membrane from reacting with the essence.

[0074] Experiment 3 Anti-wrinkle test and results

[0075] 1. Subjects: A total of 210 female volunteers, aged 50 to 35, exhibiting sagging skin and wrinkles, were randomly divided into seven groups, each consisting of 30 participants. 2. Samples: Samples prepared from wrinkle-smoothing anti-aging serums (experimental groups 1-4) and control groups 1-3.

[0076] 3. Usage: Use silicone resin to obtain wrinkle marks around the test area around the eyes of the subject. The subject should use the mask once every two days for four consecutive weeks, using one mask each time. The results will be analyzed after 28 days of use.

[0077] 4. Test method: Use an image acquisition instrument and its supporting software to obtain the images of the wrinkle target analysis positions of the test sites around the eyes of the subjects after 14 days and 28 days of treatment respectively. Use the analysis software to obtain the total wrinkle volume values respectively. Among them, the wrinkle volume value of the wrinkle target analysis position before using the sample is used as the initial value, and the wrinkle volume values of the wrinkle target analysis positions after 14 days and 28 days of use are used as the measured values.

[0078] Result calculation:

[0079] (1) Descriptive statistics: Calculate the mean, standard deviation, and change rate of each skin parameter at each time point. The change rate calculation formula = (N weeks after use - before use) / before use * 100%

[0080] (2) Normal distribution test: Conduct a normal distribution test on the above means. If the asymptotic significance (two-sided) value of the normality test > 0.050, then this series of data follows a normal distribution. In the table, the difference analysis is all compared with the basic data before use

[0081] (3) Difference analysis: Conduct a difference analysis on the above means. When both sets of data are normally distributed, use a paired T-test to analyze the difference between the two sets of data; when both sets of data are not normally distributed, use a rank sum test to analyze the difference between the two sets of data.

[0082] (4) Judgment criteria: p > 0.05 represents that there is no statistical difference between the two sets of data, indicated by "n.s."; 0.01 < p < 0.05 indicates statistical significance, indicated by "*"; 0.001 < p < 0.01 indicates significant difference, indicated by "**"; p < 0.0010 indicates extremely significant difference, indicated by "***".
