It should be understood that the embodiments described in this specification are only for the purpose of explaining the present application and are not intended to limit the present application.
For the sake of brevity, only some numerical ranges are explicitly disclosed herein. However, any lower limit may be combined with any upper limit to form ranges not explicitly recited; and any lower limit may be combined with any other lower limit to form a range not explicitly recited, and similarly any upper limit may be combined with any other upper limit to form a range not explicitly recited. Also, although not explicitly recited, each point or individual value between endpoints of a range is encompassed within the range. Thus, each point or individual value can form a range not explicitly recited as its own lower or upper limit in combination with any other point or individual value or in combination with other lower or upper limits.
In the description of the present application, it is to be noted that, unless otherwise specified, "above" and "below" are inclusive of the present number, and "plural" of "one or more" means two or more.
The above summary of the present application is not intended to describe each disclosed embodiment or every implementation of the present application. The following description more particularly exemplifies illustrative embodiments. At various points throughout this application, guidance is provided through a list of embodiments that can be used in various combinations. In each instance, the list is merely a representative group and should not be construed as exhaustive.
The foundation liquid has the advantages that the foundation liquid can decorate skin color for people, and the skin color of the whole face is more uniform and has the complexion. But has the disadvantages of poor moisture retention and waterproof effects, and easy generation of problems of floating powder, dirty makeup and makeup removal.
Based on this, the inventors have conducted extensive studies and found that by preparing an oil-in-water type foundation in a new formulation, it is possible to impart excellent Q-elastic touch to the foundation and to improve the moisture retention and water-proofing effects of the foundation.
Oil-in-water foundation liquid
In one aspect, the present embodiments provide an oil-in-water foundation, wherein the oil-in-water foundation comprises an aqueous phase component and an oil phase component, wherein,
the water phase component comprises deionized water, a humectant, a thickening agent, a suspending agent, a preservative, a chelating agent, an antioxidant, a pH regulator and a hydrogel agent;
the oil phase component comprises an emulsifier, a softening agent, a defoaming agent, toner and a dispersing agent;
the weight ratio of the water phase component to the oil phase component may be (4.5:1) - (5: 1).
According to the embodiments of the present application, the oil-in-water foundation system is in a form in which an oil phase is dispersed in an aqueous phase in the form of fine droplets, and the aqueous phase is an external phase or a dispersion medium, and is relatively moist when used, and is advantageous for retaining and moisturizing the skin, and is particularly suitable for dry skin or dry season such as autumn and winter.
The oil-in-water foundation solution provided by the application is in a gel state rather than an emulsion state under the synergistic effect of the components, has the appearance and touch of Q elasticity, is fresh and cool, has strong moisture retention and water resistance, has high stability and good antioxidant effect, is very friendly to pregnant women and users of sensitive muscles, and meets the pursuit of market consumers for comfortable skin feeling.
When the weight ratio of the water phase component to the oil phase component is (4.5:1) - (5:1), the water phase and the oil phase can be fully mixed to form a stable gel system, the affinity with skin is good, and the obtained foundation liquid has good moisturizing and waterproof effects. If the content of the oil phase component is too high, the effective components of the foundation liquid can not be easily absorbed, and pores can be blocked to make the skin rough.
In some embodiments, the aqueous phase component comprises the following components in parts by weight:
72 parts of deionized water, 6-8 parts of humectant, 0.3-0.4 part of thickener, 0.8-1.2 parts of suspending agent, 0.03-0.08 part of chelating agent, 0.3-1.0 part of antioxidant, 0.1-0.15 part of pH regulator, 0.8-1.2 parts of hydrogel agent and 0.7-1.2 parts of preservative.
In the following examples, parts by weight of each component are based on 72 parts by weight of deionized water in the aqueous component, unless otherwise indicated.
In some embodiments, the deionized water has a resistivity >1.2M Ω.
According to the embodiment of the application, the conductivity of the deionized water in the water phase is selected to be more than 1.2M omega cm, so that the influence of ions in the system on the viscosity of the system can be avoided.
According to the embodiment of the application, the moisturizing agent can form a film on the surface of the skin, so that moisture is sealed in the skin to prevent the moisture from evaporating, and meanwhile, the moisture absorption of the skin to air is not hindered, so that the proper humidity of the skin is maintained, and the problem of powder blocking caused by low moisture is avoided.

2. Moisture retention test
The test instrument used was a skin moisture content Cornemeter CM825 test probe manufactured by CK corporation of Germany (Courage + Khazaka corporation). The principle of the method is that the dielectric constants (<7) of water (81) and other substances are different greatly, according to the difference of water content, a measuring capacitor changes along with the change of capacitance of the skin, and the capacitance of the skin is in a measuring range, so that the moisture content of the skin can be measured. The capacitance measuring method is superior to other methods in that the test result is not substantially affected by polarization effect and ionic conductivity since the skin to be tested is not in unnatural contact with the test probe and almost no current flows through the skin to be tested. The instrument probe and the skin have no inertia in the process of establishing balance with water in the skin, so that the rapid measurement can be realized, and the influence of the active skin on the measurement result is eliminated.
The humidity measured by the Cornemeter CM825 test probe is represented by a Measurement Value MMV, wherein the MMV is a humidity Measurement Value (humidity Measurement Value) which ranges from 0 to 150, the MMV is greatly influenced by temperature and humidity, and a constant-temperature and constant-humidity environment is generally selected for testing.
The test method comprises the following steps: the moisture test probe is vertically pressed on the surface of the skin to be tested, the top of the probe is pressed back for a certain distance, a spring is arranged in the probe to ensure that the top of the probe keeps 0.16N of pressure to be pressed on the surface of the skin, and the host can display the MMV result of the test within one second and give out prompt sound.
In this experiment, 50 volunteer subjects were selected, and the subjects had to wash the inner sides of the forearm with clean water before the experiment, and the measurement marks were made on the inner sides of the forearm after the washing. In this experiment, the left and right forearms were each marked with 2 experimental areas. Each area was coated with a sample at 1cm intervals, each test area was 5 x 5 cm square, and 0.2g of sample was applied. After the test subject was rested in a constant temperature environment for 30min, a Corneometer was used to measure the blank paper at the test site, and 5 points were fixedly measured for each area in a certain order to obtain an average value. Then the sample is smeared by professional personnel, timing is started, the change of MMV is measured at each time point according to the design of the test,
the formula: percent increase in skin moisture content ═ MMV t -MMV 0 )/MMV 0 *100％
MMV t The MMV value of the skin after t time of smearing 0 Initial MMV value of skin before application;
the results of table 2 below were obtained by averaging the skin moisture content growth rate values of 50 volunteers.

| Sample (I) | Rate of increase of skin moisture content |
| Example 1 | 75.32％ |
| Example 2 | 71.09％ |

3. Oxidation resistance test
DPPH is also called 1, 1-diphenyl-2-trinitrophenylhydrazine, is a very stable free radical with a nitrogen center, and the stability of DPPH mainly comes from the steric hindrance of three benzene rings with resonance stabilization effect, so that an unpaired electron on the nitrogen atom in the middle cannot exert the electron pair effect which the unpaired electron on the nitrogen atom in the middle should have. The absolute ethyl alcohol emulsion of the compound is purple, has maximum absorption at the wavelength of 517nm, and has a linear relation between the absorbance and the concentration. When a radical scavenger is added thereto, DPPH radicals can be combined or substituted, so that the number of radicals is reduced, the absorbance becomes small, and the color of the solution becomes light, whereby the ability to scavenge radicals can be evaluated, that is, the ability to resist oxidation is calculated by examining the effect of a sample on scavenging DPPH radicals at a wavelength of 517 nm.
The materials required in the experiment are DPPH and absolute ethyl alcohol, and the required instrument is a spectrophotometer.
(1) Preparation of DPPH stock solution
Accurately weighing 3.5mg of DPPH reagent, dissolving with absolute ethyl alcohol, transferring into a 10mL volumetric flask, fixing the volume to the scale with the absolute ethyl alcohol, adding 2mL of the solution into a 100mL volumetric flask, shaking up to obtain DPPH stock solution with the concentration of 0.0178mmol/L, and placing the DPPH stock solution in a refrigerator for storage.
(2) Determination of DPPH radical scavenging Rate
Adding 4.0mL of DPPH solution and 1mL of the sample in the embodiment 1-7 into a 10mL colorimetric tube in sequence, uniformly mixing, measuring an absorbance value (A) at a wavelength of 517nm by using a cuvette, marking the absorbance value as Ai, measuring the absorbance value after storing for 30min in a dark place at room temperature, marking as Aj, adding only DPPH ethanol solution in a contrast test, wherein the absorbance value is Ac, and calculating the free radical clearance K according to the formula:
k (%) [1- (Ai-Aj)/Ac ]. 100%; the test was repeated three times, and K was averaged, and the test results are shown in table 3 below.
TABLE 3 radical scavenging rates for samples from examples 1-7
From the above results, it can be seen that the oil-in-water type foundation solutions of examples 1 to 7 all had a radical scavenging rate higher than 92.98%, indicating that they all had excellent antioxidant ability, wherein the antioxidant ability was the best because of the high content of vitamin E and ascorbic acid in example 4.
From the test results, the oil-in-water foundation solutions of examples 1 to 7 have good heat resistance, cold resistance and stability, and the water-locking, moisture-preserving and oxidation resistance capabilities can meet the actual requirements, so that the oil-in-water foundation solutions have innovativeness and novelty in the cosmetic market and have strong product competitiveness.
To sum up, the oil-in-water foundation solution provided by the application is gel-like, has the appearance and touch of Q bullet, is fresh and cool, moisturizes, has strong waterproof property, has high stability and good antioxidant effect, is very friendly to pregnant women and users of sensitive muscles, and meets the pursuit of market consumers for comfortable skin feeling.
While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
