Description

Technical Field

[0001] This invention relates to the field of cosmetics technology, and in particular to a mild makeup remover and its preparation method. Background Technology

[0002] Makeup removers include cleansing oils, cleansing milks, and cleansing waters. Among them, cleansing waters generally don't leave a heavy, greasy feeling and are popular with many consumers. The main cleansing ingredient in cleansing waters is surfactants. A proper combination of surfactants is essential for effective makeup removal while remaining gentle on the skin. After using makeup removers, to avoid residual surfactants and other ingredients causing harm, it's generally necessary to wash the skin with a facial cleanser. This not only increases the hassle of use but also raises costs. Therefore, developing a makeup remover with a well-balanced surfactant combination that effectively removes makeup while being gentle, non-irritating, and requiring no rinsing has a promising market prospect.

[0047] Effect verification

[0048] I. Makeup removal effect

[0049] The sample of Comparative Example 1 is used as Sample 1, and the sample of Example 1 is used as Sample 2. YSL lipstick, Maybelline lip gloss, KATE eyeliner, and BB cream are used as test samples to compare the makeup removal ability of Comparative Example 1 and Example 1.

[0050] Experiment 1: (1) YSL lipstick is used to draw on the arm three times repeatedly, and allowed to dry for 2 hours; (2) cosmetic cottons with equal proportions of Sample 1 makeup remover and Sample 2 makeup remover are respectively applied to the makeup area for 3-5 seconds, and then gently wiped 1-2 times, which can be completely removed, as shown in Figure 1 . It can be seen that the makeup removal effect of the sample of Example 1 (Sample 2) on YSL lipstick is better than that of the sample of Comparative Example 1 (Sample 1).

[0051] Experiment 2: (1) Maybelline lip gloss is used to draw on the arm three times repeatedly, and allowed to dry for 2 hours; (2) cosmetic cottons with equal proportions of Sample 1 makeup remover and Sample 2 makeup remover are respectively applied to the makeup area for 10 seconds, and then gently wiped 3-5 times, as shown in Figure 2 . It can be seen that the makeup removal effect of the sample of Example 1 (Sample 2) on Maybelline lip gloss is better than that of the sample of Comparative Example 1 (Sample 1).

[0052] Experiment 3: (1) KATE eyeliner is used to draw on the arm three times repeatedly, and allowed to dry for 2 hours; (2) cosmetic cottons with equal proportions of Sample 1 makeup remover and Sample 2 makeup remover are respectively applied to the eyeliner area for 10 seconds, and then wiped on the arm once, as shown in Figure 3 . It can be seen that the makeup removal effect of the sample of Example 1 (Sample 2) on KATE eyeliner is better than that of the sample of Comparative Example 1 (Sample 1).

[0053] Experiment 4: (1) BB cream is used to draw on the arm three times repeatedly, and allowed to dry for 2 hours;

[0054] (2) cosmetic cottons with equal proportions of Sample 1 makeup remover and Sample 2 makeup remover are respectively applied to the area with BB cream for 10 seconds, and then wiped on the arm once, as shown in Figure 4The results are shown in the following table 3-4. Table 2 is a score index table.

[0055] II. Testers' trial

[0056] Thirty testers who often use make-up and make-up remover were selected, each of whom tried the make-up remover samples of examples 1-3 and comparative examples 1-3, and scored the use effect of the make-up remover samples after use, and the number of people was counted, and the results are shown in the following table 3-4. Table 2 is a score index table.

[0057] Table 2 Score index table

[0058]

[0059] Table 3 Make-up removal effect evaluation table

[0060]

[0061] From the records in table 3, it can be seen that most of the testers' evaluation of the samples of examples 1-3 is high, and the make-up removal effect of lip gloss, eye make-up and full face is good. The samples of comparative examples 1-3, due to the change of surfactant, the make-up removal effect is reduced, and the make-up removal ability is not as good as examples 1-3.

[0062] Table 4 Use effect evaluation table

[0063]

[0064] From the records in table 4, it can be seen that the samples of examples 1-3 are better than comparative examples in mildness, use skin feel, rinsing and moisturizing. The samples of comparative examples 1-3, due to the change of surfactant, the use effect evaluation is not as good as examples 1-3. This shows that the use of suitable surfactant combination in the examples of the present application not only makes the make-up removal effect excellent, but also ensures the mildness of the product, which is mild and non-irritating, does not cause skin sensitivity, is refreshing and not greasy, has good skin friendliness, is easy to rinse, does not leave dirt residues, has good moisturizing effect after rinsing, and the skin is moist and not tight.

[0065] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application are within the scope of the present application.
