[0002] Liquid foundation is a cosmetic product that is applied to the entire face to modify and cover the skin. It can complement the color of the face, cover the pigmentation on the skin, and improve the roughness of the skin. Liquid foundation can be divided into oily skin, dry skin, and mixed skin according to skin type; according to texture, it can be divided into liquid foundation, cream foundation, and powder foundation. These classifications enable liquid foundation to better meet the needs of different groups of people and occasions. As a basic product in cosmetics, with the growing demand for beauty and personal care, the market demand for liquid foundation is also expanding.

[0003] CN117243873A discloses a three-phase liquid foundation and a preparation method thereof. The three-phase liquid foundation in the invention includes phase A, phase B, and phase C; the raw materials for preparing phase A include oil A, film former, and activator; the raw materials for preparing phase B include moisturizer, thickener, contour powder beads, water-soluble active substance, and water; the raw materials for preparing phase C include oil ester B and oil-soluble active substance; the three-phase liquid foundation prepared by the invention has a novel dosage form, beautiful appearance, moisturizing and light, good docility, and excellent skin care effects, and has the skin care effects of moisturizing, brightening, oil control, soothing and repairing, and anti-dullness.

[0004] CN112294722A discloses a liquid foundation and a preparation method thereof. The liquid foundation is prepared from the following raw materials in parts by weight: 12-15 parts of Atractylodes macrocephala, 10-12 parts of Angelica dahurica, 20-30 parts of Honeysuckle, 30-50 parts of Gardenia jasminoides, 1-2 parts of Borneolum, 20-30 parts of White Peony Root, 3-5 parts of Paeonia suffruticosa, 0.5-0.8 parts of Paraben, 3-5 parts of Titanium Dioxide, 2-3 parts of Sodium Pyrrolidone Carboxylate, 15-20 parts of Glycerin, 2-3 parts of Cetearyl Alcohol, 0.2-0.3 parts of Monoolein, 0.2-0.3 parts of Ascorbyl Palmitate, and 10-15 parts of deionized water. The liquid foundation prepared by the invention can reduce facial skin sweating and dryness when used in summer, under high temperature ambient light, or during exercise, and has a good skin-adhering effect.

[0005] However, the foundation liquid provided by the above-mentioned prior art is prone to problems such as makeup removal, powder sticking, dullness, etc. during use, and poor adhesion will affect the natural beauty of the makeup. Therefore, it is of great significance to develop a product with good application feel, good skin adhesion and longer lasting makeup effect. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention aims to provide a liquid foundation and a preparation method thereof. The liquid foundation can significantly improve the makeup holding performance by adding a specific film-forming agent.

After 6 hot and cold cycle temperatures of -15°C / 48°C, the products were observed for abnormal phenomena such as discoloration, demulsification, precipitation, turbidity, stratification, etc. The test results are shown in Table 1.

[0094] Table 1

[0095]

[0096]

[0097] It can be seen from the data in Table 1 that the foundation liquid provided by the present invention has excellent high and low temperature stability regardless of high temperature, low temperature or hot and cold cycle environment, and the composition of the film-forming agent affects the stability of the product.

[0098] Test Example 2: Makeup lasting ability test

[0099] 108 volunteers were selected and randomly divided into 18 groups, with 6 people in each group. The products of Examples 1-13 and Comparative Examples 1-5 were used respectively. After washing, the volunteers marked their faces. The test area of ​​the sample was 5×5 cm. 2, the sample dosage is 0.2g, the sample is applied, the timing is started, and the volunteers are observed to apply the sample until the makeup is removed, then the timing is stopped, and the average of the duration results is calculated to evaluate the makeup holding ability of the sample. The test results are shown in Table 2:

[0100] Table 2

[0101]

[0102]

[0103] It can be seen from the results in Table 2 that, compared with Comparative Example 5, the liquid foundation provided in Examples 1-3 of the present invention can have excellent long-lasting makeup performance by adding a specific film-forming agent.

[0108] Test Example 3 Consumer Sensory Effect Evaluation

[0109] The volunteers are the same group of volunteers as in Test Example 2, and the grouping is consistent. Each group uses the products of Examples 1-13 and Comparative Examples 1-5 for sensory evaluation, and the evaluation indicators are mildness, lightness and skin-fitting feel.

[0110] Test method: The subjects used the product once a day for 14 consecutive days and then made a sensory evaluation of the product using a 5-point system: 4.5 points and above, indicating very good, very satisfied; 4-4.5 points, good; 3-4 points, acceptable; and 3 points or less, poor, unacceptable. The scores of each group were the average of 10 people, and the results are shown in Table 3.

[0111] Table 3

[0112]

[0113]

[0114] As can be seen from Table 3, the liquid foundation of the present invention can form a protective film on the skin surface by adding a specific film-forming agent, and has a light texture and excellent mildness and close skin feel.

[0115] Test Example 4 Irritation Evaluation

[0116] The red blood cell haemolysis test (RBC) is one of the alternative methods to the rabbit eye irritation test. The basic principle is to evaluate the damage of chemicals to eye tissue cells by measuring the amount of cell hemoglobin dissolution and the degree of denaturation. The RBC test can be used to evaluate the eye irritation of cosmetics.

[0117] The samples of Examples 1-13 were subjected to red blood cell hemolysis experiments. The experiments adopted the RBC experimental test method and judgment criteria of the European Alternative Method Validation Center. The specific judgment criteria are shown in Table 4, where HD 50 is the sample concentration when 50% of red blood cells are hemolyzed, DI is the protein denaturation index, and L / D is HD 50 Ratio to DI.

[0118] Table 4

[0119]

[0120]

[0121] The irritation results of the tested samples prepared in Examples 1-13 are shown in Table 5.

[0122] Table 5

[0123] sample L / D Grading Example 1 ＞100 Non-irritating Example 2 ＞100 Non-irritating Example 3 ＞100 Non-irritating Example 4 ＞100 Non-irritating Example 5 ＞100 Non-irritating Example 6 ＞100 Non-irritating Example 7 ＞100 Non-irritating Example 8 ＞100 Non-irritating Example 9 ＞100 Non-irritating Example 10 ＞100 Non-irritating Embodiment 11 ＞100 Non-irritating Example 12 ＞100 Non-irritating Example 13 ＞100 Non-irritating

[0124] From the sample irritation results in Table 5, it can be seen that the irritation classification of the liquid foundation prepared in Examples 1 to 13 of the present invention is non-irritating, which shows that the ingredients of the liquid foundation of the present invention are mild and non-irritating.
