Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of biotechnology, and in particular to an oil-in-water makeup remover composition. Background Art

[0002] Makeup products mainly refer to cosmetic products for face, eyes, lips, etc. If makeup is not removed thoroughly, skin problems such as clogged pores, skin allergies, dry skin, etc. may occur. At present, common makeup removal compositions usually add oils and / or surfactants to achieve the purpose of makeup removal.

[0003] However, when the above method is adopted, the following technical problems often occur:

[0004] First, makeup removers with high oil content are often too thin in texture, which may cause eye irritation when accidentally entering the eyes. Although makeup removers with low oil content can better overcome the texture problem, they will lead to a decrease in the cleansing ability of the makeup removers.

[0005] Second, in order to solve the problem of too thin texture of makeup remover compositions with high oil content, high molecular weight substances with thickening effect are often added to solve the problem of too thin texture. However, high molecular weight substances are difficult to be effectively rinsed off and are very likely to remain on the skin surface, causing obvious film-forming feeling.

[0006] The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

[0133] Rotor speed: 6.0 rpm.

[0134] Skin feel evaluation method description

[0135] 30 random users aged between 18 and 45 who have the habit of using makeup were selected as subjects.

[0136] Grease Residue Evaluation Method Description

[0137] Three parallel experiments were conducted respectively.

Among them, the skin oil content A represents the skin oil content before the sample is applied (without using the water-in-oil type makeup remover composition). The skin oil content B represents the skin oil content measured after using 2 mL of the water-in-oil type makeup remover composition, and then washing with deionized water to remove the water-in-oil type makeup remover composition, and then drying it. Specifically, the treatment objects corresponding to the skin oil content A and the skin oil content B are both pig skin, and the pig skin is treated with the same number of times and the same intensity. In practice, the skin oil content test probe can use a skin oil tester with the model "Sebumeter SM 815". Among them, the smaller the value of the oil residue, the less oil it represents, that is, the less oil residue on the pig skin surface.

[0138] The environmental conditions for grease residue measurement are: constant temperature (25±1°C), constant humidity (50±10 RH%)

[0139] Calculation method for oil residue: Oil residue = (skin oil content A - skin oil content B) / skin oil content A × 100%.

[0140] How to test makeup dissolving speed

[0141] First, take 0.1 g of lipstick and apply it evenly to the test area, where the test area is 2×2 cm of the skin surface. Under the conditions of 50% humidity and 20°C, wait for 30 minutes until the lipstick is completely dry. Then, take 0.2 g of a sample containing an oil-in-water makeup remover composition and apply it to the above test area. Control the strength of the fingertips, rub repeatedly, and count the time from the beginning of rubbing until the lipstick is completely removed from the skin surface. The unit is seconds.

[0142] Stability Evaluation Method Description

[0143] A sample containing the oil-in-water makeup remover composition was placed in a PET bottle and stored in a constant temperature incubator at 45±2°C, and the state of the sample was observed.

[0144] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0145] Example Description

[0146] Experimental Group 1

[0147] Among them, experimental group 1 includes: Example 1, Comparative Example 1-1, Comparative Example 1-2, Comparative Example 1-3 and Comparative Example 1-4.

[0148] Specifically, the names and contents of the components in the embodiments and comparative examples are shown in Table 1 below:

[0149] .

[0150] Among them, the component named "oil" is hydrogenated polyisobutylene.

[0151] Preparation method

[0152] The preparation methods of the samples corresponding to the experimental examples and comparative examples included in Experimental Group 1 are as follows:

[0153] In the first step, the oil or oil containing oily components is mixed with an emulsifier and heated to 65-80°C to obtain an oil phase.

[0154] Among them, the one with the serial number "1" in Table 1 is oil or oil containing oily components. The ones with the serial numbers "2" to "6" in Table 1 are all emulsifiers.

[0155] In the second step, water or water containing water-soluble components is heated to 75-80°C to obtain an aqueous phase.

[0156] Among them, the one with the serial number "7" in Table 1 belongs to water or water containing water-soluble components.

[0157] In the third step, the oil phase and the water phase are mixed until homogeneous, and the temperature is lowered to 35-40° C. to obtain the corresponding samples (makeup removal compositions) of the experimental examples and comparative examples included in the experimental group 1.

[0158] Evaluation Results

[0159] According to the aforementioned evaluation method, the corresponding samples of Example 1, Comparative Example 1-1, Comparative Example 1-2, Comparative Example 1-3 and Comparative Example 1-4 included in the experimental group 1 were respectively subjected to viscosity evaluation, skin feel evaluation and oil residue evaluation. The evaluation results are shown in Table 2:

[0160] .

[0161] Among them, the oleth-10 used in Example 1 and the emulsifiers selected in Comparative Examples 1-1 to 1-4 are all emulsifiers with high HLB values ​​(the larger the HLB value, the stronger the hydrophilicity), and only emulsifiers with high HLB values ​​can exist in an environment with a large amount of oil, otherwise the emulsifier will easily leave the water-oil interface and enter the oil, thereby destroying the emulsification system of the makeup remover product and causing product stratification. Analysis of Table 2 shows that compared with Comparative Examples 1-1 to 1-4, Example 1 can not only effectively improve the consistency of the water-in-oil system containing a large amount of oil, but also significantly reduce the oil remaining on the skin after washing with water. On the contrary, the oil residue in Comparative Examples 1-1 to 1-4 is obvious.

[0168] Among them, the component named "oil" is hydrogenated polyisobutylene.

[0169] Preparation method

[0170] The preparation methods of the samples corresponding to the experimental examples and comparative examples included in Experimental Group 2 are as follows:
