Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a hydrating cosmetic composition based on plant extracts and a preparation method thereof. Background Art

[0002] China's cosmetics industry as a whole is showing a growth trend. The market size will reach 516.9 billion yuan in 2023 and is expected to increase to 579.1 billion yuan in 2025. Among them, the market size of the skin care industry will be 280.4 billion yuan in 2023, a year-on-year increase of 9.3%. With the increase in national disposable income and the enhancement of aesthetic awareness, consumers' awareness of skin care is increasing, and the consumption concept of skin care products has been updated, which has promoted the healthy development of the skin care industry. When choosing cosmetics, consumers give priority to the ingredients and efficacy of the products. However, the most basic effect of skin care is hydration, which is the premise of our skin care and makeup. Therefore, our requirements for hydrating cosmetics are getting higher and higher. Not only do we need the products to have obvious hydrating and water-locking effects, but they must also be gentle and non-irritating, and try not to harm the skin as much as possible.

[0003] There are many types of hydrating cosmetics available, but the hydrating effects are mostly unsatisfactory. Some only have hydrating effects but cannot moisturize the skin. The evaporation of water on the skin surface may make the skin drier. Moreover, some hydrating cosmetics may contain ingredients such as alcohol and fragrances. These ingredients may cause discomfort or allergic reactions to certain skin types, especially sensitive skin. Use of these ingredients may cause facial ulcers and even disfigurement in severe cases. This is very unsafe.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0059] Experimental Example 1

[0060] 120 volunteers aged between 20 and 30 were selected, both male and female, with healthy skin, no history of skin diseases and allergies, no serious chronic wasting diseases, etc., and were evenly divided into 6 groups, and the test samples in the above embodiments and comparative examples were tested respectively. The volunteers in each group wiped and cleaned their faces with dry facial tissues, and after cleaning, the measurement areas were marked on the left and right faces of the subjects;

[0061] Before the formal test, the subjects sat quietly for 60 minutes in an environment with a temperature of 25±2℃ and a humidity of 50±2%, without drinking water and keeping the body relaxed. 5mL of the test sample was applied to the test area, and the skin moisture content of the test area and the blank control area was measured at 0min, 30min, 60min, 120min, and 180min. The test of the same group of subjects was completed by the same measurement personnel, and the test average value was calculated.

[0062] Calculation formula: W% = (W1-W0) / W0×100%, Note: W% = skin moisture content increase percentage (MMV), W0 = skin moisture content before using the sample, W1 = skin moisture content after using the sample;

[0063] The experimental results are shown in Table 1:

[0064] Table 1 Skin moisture content

[0065]

[0066] Experimental Example 2

[0067] The hemoglobin EI values ​​of the above embodiments and comparative examples were tested using a hemoglobin tester, in which the German MexameterMX18 was selected as the measuring instrument. The test population was volunteers aged 18 to 50 years old, with healthy skin and no history of skin diseases and allergies. The volunteers were divided into 3 groups, with 50 people in each group. The test should be conducted at room temperature of 20±2°C and relative humidity of 50±5%. The subjects were allowed to stand for 50 minutes before testing the relevant data.

[0068] Specific experimental process: This experiment was divided into 3 groups, each group was divided into 2 teams, one team used the example cosmetic composition, and the other team used the comparative example cosmetic composition, applied to the face twice a day, morning and evening, for 4 weeks, and the hemoglobin EI value of the skin of the test site was tested using a hemoglobin tester;

[0069] The experimental results are shown in Table 2:

[0070] Table 2 EI value of skin hemoglobin content

[0071]

[0072] According to the data in Table 1, it can be seen that the hydrating cosmetic composition provided by the present invention, with reference to Examples 1, 2 and 3, increases the skin moisture content by 50.45-65.70% after use, and increases the skin moisture content by 15.98-21.12% after 180 minutes of use, and has good hydrating and water-locking effects. Among them, the hydrating effect of the cosmetic composition prepared in Example 3 is the best, which is the best embodiment of the present invention;

[0073] It can be seen that the higher the proportion of the plant extract added, the better the moisturizing and water-locking effects of the moisturizing cosmetic composition;

[0074] Referring to comparative example 1, the moisturizing effect of the cosmetic composition was the worst when no plant extract was added. Referring to example 2 and comparative example 2, when the same weight of plant extract was added, the moisturizing effect of the cosmetic composition was not as good as that of the cosmetic composition emulsified with an emulsifier without emulsification. Referring to comparative example 3, when the homogenization treatment was not performed, the moisturizing and water-locking effects of the moisturizing cosmetic composition would also be worse.

[0075] According to the data in Table 2, after the subjects used the present invention for 4 weeks, the reduction in the hemoglobin EI value of the subjects' skin in Example 3 was the largest, followed by Example 2, and then Example 1. It can be seen that the higher the amount of plant extract used in the present invention, the better the repair effect on the skin;

[0076] Referring to comparative example 1, no plant extract was added, and the effect of the composition on the skin was the worst. Referring to example 2 and comparative example 2, when the same weight of plant extract was added, the cosmetic composition was not emulsified with an emulsifier, and the skin repair effect was not as good as the cosmetic composition emulsified with an emulsifier. Referring to comparative example 3, when the composition was not homogenized, the skin repair effect of the hydrating cosmetic composition was also worse. It can be seen that the hydrating cosmetic composition based on plant extracts and the preparation method thereof described in the present invention can not only deeply hydrate and moisturize, but also repair the skin barrier and improve skin quality.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
