Description

Technical Field

[0001] The present invention belongs to the technical field of daily-use cosmetics, and particularly relates to a two-color cleansing mud mask combination and a preparation method thereof. Background Art

[0002] CN116350528A discloses a zeolite temperature-sensitive cleansing mud mask and a preparation method and a using method thereof. The cleansing mud mask comprises the following raw materials: glycerol, glyceryl stearate, PEG-100 stearate, cetearyl alcohol, bisabolol, ginger root extract, Cambrian blue mud, kaolin, erythritol, lactic acid, glycolic acid, lactobionic acid, sustained-release salicylic acid, panthenol, zeolite, butanediol, p-hydroxyacetophenone, 1,2-hexanediol, etc. The cleansing mud mask obtained by compounding the above components has a self-steam hot compress effect, and when applied to the skin, it can truly increase the temperature of the application part, help open pores, soften cutin, strongly adsorb, and deeply clean pores.

[0003] CN114939099A discloses an oil-control mud mask composition and a preparation method thereof. The provided oil-control mud mask composition contains a cleansing mud and a plankton extract. Among them, the cleansing mud can play a role in cleaning the skin and adsorbing oil through adsorption. The plankton extract can, on the one hand, synergistically enhance the adsorption effect of the cleansing mud on oil, on the other hand, can significantly inhibit the oil secretion at the application part, and on the third hand, can effectively reduce the irritation of the cleansing mud to the skin. Therefore, the mud mask composition has the advantages of strong cleaning ability, good oil-control effect and low skin irritation.

[0004] However, due to the differences in different regional parts of the skin and the living habits of people in different regions, etc., the use of the above-mentioned mud masks has limitations, and situations of over-cleaning or insufficient cleaning power often occur. Therefore, it has important application significance to study a cleansing mud mask product applicable to multiple application scenarios. Summary of the Invention

[0136] Test Example 1 Oil Control Effect Test

[0137] Test Samples: Cleansing mud mask samples provided in Examples 1 - 15 and Comparative Examples 1 - 6.

[0138] Test method: 126 volunteers aged 18 - 50 years old were selected and randomly divided into 21 groups with 6 people in each group. After cleansing their faces in the morning and evening, each volunteer took an appropriate amount of the mud mask and evenly applied it to the entire face (first apply component A for 3 minutes, clean it with water and then use component B, and Comparative Examples 1 and 2 were each used twice). After 15 minutes, wash it off with clean water and keep using it for 28 days. Before using the product, 14 days after using the product, and 28 days after using the product, the volunteers were arranged to conduct an oil control efficacy test to obtain the skin oil content. The oil control efficacy test was carried out 5 times on the forehead area using the Sebumeter, an oil test probe of cuotometer MPA580 manufactured by Courage + Khazaka GmbH (German CK company), and the average value was taken.

[0139] Calculate the change rate at 14 and 28 days of using the product according to the following formula:

[0140] In the formula, D0 is the skin parameter baseline value before using the product in the test area; D14 is the skin parameter value 14 days after using the product in the test area; D28 is the skin parameter value 28 days after using the product in the test area.

[0141] The test results are shown in Table 1:

[0142] Table 1

[0143]

[0144]

[0145] It can be seen from the test results that: by comparing Comparative Examples 1, 2 with Examples 1 - 3, it can be seen that the combined use of the cleaning and oil control combination of the present invention has excellent oil control effect and can regulate the water - oil balance of the skin after long - term use.

[0146] It can be known from Comparative Examples 3 - 6 that the choice of filler has a great influence on the oil control effect of the product.

[0147] Test Example 2 Cleaning Power Test

[0148] 105 volunteers were divided into 21 groups with 5 people in each group. The 21 groups of volunteers respectively used the products prepared in Examples 1 - 15 and Comparative Examples 1 - 6. The specific method was as follows: All volunteers uniformly cleaned the flexor sides of the left and right forearms, gently blotted the water with a tissue, and then marked 3 areas with an area of 4 cm * 4 cm as the test areas. The distance between each area was at least 2 cm. The 3 test areas were numbered as L1, L2, L3 and R1, R2, R3 respectively. After sitting still for 20 minutes, the microscope was used to collect images of each test area, and the L*, a*, b* values of the initial skin state were measured with a spectrophotometer.

[0149] Then, a microscope was used to collect images of each test area, and a spectrophotometer was used to measure the L*, a*, and b* values of the skin after applying the liquid foundation.

[0150] Regions L1, L2, L3 and R1, R2, R3 were cleaned by applying an appropriate amount of the product of the example or the product prepared by the comparative example (first apply the component A for 3 minutes, then clean with water and then use the component B, and comparative examples 1 and 2 were each used twice). Then rinse thoroughly with water and gently blot dry with a tissue. Sit quietly for 30 min, use a microscope to collect images of each test area, and use a spectrophotometer to measure the L*, a*, and b* values of the skin after cleaning. L* represents black and white degree. The larger the L* value, the whiter the skin tends to be, and vice versa, it tends to be black; a* represents red and green degree. The larger the a* value, the redder the skin tends to be, and vice versa, it tends to be green; b* represents blue and yellow degree. The larger the b* value, the more yellow the skin tends to be, and vice versa, it tends to be blue. The laboratory was kept at a constant temperature and humidity, with a test temperature of 23 °C to 24 °C and a relative humidity of 50% to 60%.

[0151] Calculation method of detergency: Calculate the color difference of the skin after applying the liquid foundation compared with the initial state, denoted as △E (after application); calculate the color difference of the skin after cleaning compared with the initial state, denoted as △E (after cleaning). △E can comprehensively reflect the three-dimensional change of skin chromaticity. The larger the △E value, the more obvious the skin color change, and the smaller the △E value, the closer the skin color is. Calculate the detergency through △E, and the calculation formula is:

[0152] △E = SQRT(△L* 2 + △a* 2 + △b* 2 )

[0153] Detergency = (△E (after application) - △E (after cleaning) / △E (after application)) × 100%

[0154] The results are shown in Table 2:

[0155] Table 2

[0156]

[0157]

[0158] It can be seen from the data in Table 2 that the product involved in the present invention has very good removal ability for the liquid foundation, and the combined use of component A and component B has a synergistic effect in terms of cleaning effect. In addition, the combination of kaolin with a specific particle size can better improve the detergency of the product.

[0159] Test Example 3 Evaluation of Consumer Sensory Effects

[0160] Select 126 female volunteers aged between 30 and 35 as the test subjects, and randomly divide them into 21 groups with 6 people in each group. Test method: The test subjects used the products of Examples 1-15 and Comparative Examples 1-6 respectively. The test subjects used daily skin care products normally during the day and used the test products once every night (first apply Component A for 3 minutes, clean with water and then use Component B, and Comparative Examples 1 and 2 were each used twice). They were used continuously for 14 days. After the use, the test subjects scored the use effect on a 5-point scale: 4.5 points and above indicated very good and very satisfied; 4-4.5 points indicated relatively good; 3-4 points indicated medium and acceptable; below 3 points indicated bad and unacceptable. The score of each group was the average value of 10 people, and the results are shown in Table 3.

[0161] Table 3

[0162]

[0163]

[0164] As can be seen from Table 3, the cleansing mud mask of the present invention has good post-washing comfort, cleansing effect and rinsability.

[0165] Test Example 4 Irritation Evaluation

[0166] The red blood cell haemolysis test (RBC) is one of the alternative methods for the rabbit eye irritation test. The basic principle is to evaluate the damage of chemicals to eye tissue cells by measuring the amount of hemoglobin released from cells and the degree of denaturation. The RBC test can be used to evaluate the eye irritation of cosmetics.

[0167] The red blood cell haemolysis test was carried out on Component A and Component B in the samples of Examples 1-15 respectively. The test adopted the RBC 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 undergo haemolysis, DI is the protein denaturation index, and L / D is the ratio of HD 50 to DI.

[0168] Table 4

[0169] L / D Classification L / D > 100 Non-irritating 10 < L / D ≤ 100 Slightly irritating 1 < L / D ≤ 10 Mildly irritating 0.1 < L / D ≤ 1 Moderately irritating L / D ≤ 0.1 Severely irritating

[0170] The irritation results of the test samples prepared in Examples 1-15 are shown in Table 5.

[0171] Table 5

[0172]

[0173]

[0174] From the sample irritation results in Table 5, it can be seen that the irritation grades of component A and component B in the products prepared in Examples 1-15 of the present invention are non-irritating, indicating that the cleansing mud masks of the present invention are all mild and non-irritating.
