Examples of the experiments

1. Cleaning ability test

To test the cleansing ability of the cleansing milks of examples 1 to 5 and comparative examples 1 to 5, 10 test persons were randomly selected and divided into 10 groups. The area of the arm 2 cm x 2 cm was painted with lipstick and BB cream. The skin was then allowed to expose for 15 minutes at room temperature. After 15 minutes, the cleansing milks of examples 1 to 5 and comparative examples 1 to 5 were applied to the skin of makeup, rubbed with a hand while rolling for 25 times, rinsed with running warm water, and rubbed with another roll for 10 times. After removing the moisture from the skin surface gently, the makeup removing ability was judged by visual comparison. Counting the scores of the cleaning ability of each group of facial cleanser according to the following scoring rules;

(1) the complete erasure is 10 minutes;

(2) the residual amount is 10 percent and is counted as 9 minutes; the residual amount of 20 percent is 8 minutes, and the residual amount of 30 percent is 7 minutes; by analogy, the residual amount of 100% is 0 min.

The cleansing power score statistics for each group of facial cleansers are shown in table 2.

TABLE 2 cleansing power of cleansing milks of examples 1 to 10 and comparative examples 1 to 5

Example 1	Example 2	Example 3	Example 4	Practice ofExample 5
					Cleaning power (fen)	7	8	7	8	8
Comparative example 1	Comparative example 2	Comparative example 3	Comparative example 4	Comparative example 5
					Cleaning power (fen)	3	6	5	5	2

As can be seen from the above Table 2, the cleansing milks of examples 1 to 5 had strong cleansing power, and the cleansing power scores were 7 or more, indicating that the cleansing milks of examples 1 to 5 had certain makeup removing and cleansing power for makeup. In comparative examples 1-5, however, the cleaning ability was significantly worse than in examples 1-5, and the cleaning ability was scored around 2-5.

Specifically, since the specific compositions of the anionic surfactant, the zwitterionic surfactant and the nonionic surfactant in comparative example 1 are different from those in examples 1 to 5, i.e., the anionic surfactant is potassium cocoyl glycinate alone, the zwitterionic surfactant is sodium dodecyl phosphate alone, the nonionic surfactant is PEG-80 sorbitan laurate alone, and the cleaning power is scored as 3, it is shown that the cleaning power of the facial cleanser is reduced by using the anionic surfactant alone, the zwitterionic surfactant alone and the nonionic surfactant alone under the condition that other conditions are not changed; the components in the composite surfactant provided by the invention are synergistic, so that the makeup removing and cleaning capabilities of the makeup remover are improved.

In comparative example 2, only potassium cocoyl glycinate was used as anionic surfactant, which is the same as the surface active component; likewise, in comparative example 3, sodium dodecyl phosphate alone was used as the zwitterionic surfactant; in comparative example 4, only PEG-80 sorbitol laurate was used as the nonionic surfactant, and as can be seen from the data in Table 2, the cleansing power of comparative examples 2-4 was improved but was inferior to that of examples 1-5, indicating that in the present invention, the groups of surfactants act synergistically and the lack of any one of them affects the cleansing power and makeup removal ability of the facial cleanser. In comparative example 5, in which the mass fraction of the added oil ester was 10% more than 0.5 to 5% required in the present invention, cleansing power and makeup removing power were drastically reduced to only 2, because the content of the oil ester was excessive, contact of the surfactant with the skin was reduced during cleansing, activity of the surfactant was reduced, and thus cleansing power of the facial cleanser was affected.

2. Foaming force test of facial cleanser

Using a hand beating method, taking 3g of the facial cleanser of the examples 1-5 and the comparative examples 1-5 on unwetted hands, adding 30g of water at 25 ℃, kneading the mixture by hands for 50 times to foam, comparing the volumes of the generated foams, namely transferring the foams into a measuring cup, testing the volumes of the foams, judging the foaming capacity of the facial cleanser by comparing the volumes of the foams, wherein the specific scoring standard is as follows: the volume of the foam was greater than 10mL and was 10 minutes, the volume of the foam was 9-10mL and was 9 minutes, the volume of the foam was 8-9mL and was 8 minutes, and by analogy, the volume of the foam was 0 minute when the volume of the foam was less than 1mL, and the results are shown in table 3.

TABLE 3 foaming ability of the facial cleansers of examples 1-5 and comparative examples 1-5

Example 1	Example 2	Example 3	Example 4	Example 5
					Foaming power (fen)	7	8	7	8	9
Comparative example 1	Comparative example 2	Comparative example 3	Comparative example 4	Comparative example 5
					Foaming power (fen)	3	6	5	5	2

As can be seen from Table 3, the foaming ability of examples 1 to 5 was scored above 7, while the foaming ability of comparative examples 1 to 5 was scored around 2 to 6, and the foaming ability of examples 1 to 5 was superior to that of comparative examples 1 to 5. Specifically, since in examples 1 to 5, various surface activities were compounded as a surfactant of the cleansing milk, whereas in comparative examples 1 to 4, the surface activity of each group of cleansing milk was a single component, resulting in poor foaming ability of the cleansing milk; it is also stated that in the present invention, various surface activities in the facial cleanser are synergistic, and the synergistic effects are not simply added but are provided to a great extent in foaming ability.

3. Usability assessment

30 women aged 20 to 30 were randomly selected and divided into 3 groups of 10, and the facial cleansers of example 2, comparative example 4 and 5 were used by the users of each group, and after 4 weeks of continuous use, the use feelings of spreadability, adhesion, stickiness, and moisturizing feeling of the facial cleansers by the users were compared to obtain corresponding scores, and the results are shown in table 4. Wherein the user feels very good at 5 points, good at 4 points, generally 3 points, 2 points, and very poor at 1 point.

Table 4 evaluation of usability of facial cleanser of example 2, comparative examples 4 and 5

	Example 2	Comparative example 4	Comparative example 5
				Diffusivity	5	3	2
Adhesion force	5	2	3
				Viscosity	5	1	3
Moisture retention	4	3	2

As can be seen from the above Table 4, the cleansing milk of example 2 was superior in the feeling of use in terms of spreading power, adhesion, etc., to those of comparative examples 4 and 5. This is because, in comparative example 4, the nonionic surface active agent used was 12% of PEG-80 sorbitol laurate, while the nonionic surface active agent in example 2 was a mixture of three; the viscosity of the cleansing milk of comparative example 2 was inferior to that of the cleansing milk of example 2, and the adhesive force of the cleansing milk of comparative example 4 was also inferior to that of example 2; in terms of retention and diffusion, comparative example 4 is better than comparative example 5, but is also worse than example 2; it can be shown that the composition of the nonionic surfactant directly affects the viscosity and adhesion of the facial cleanser, and has little influence on the moisture retention and spreadability.

In comparative example 5, 10% of the oil ester was added, which was more than 0.1-5% of the present invention. The moisturizing property and spreadability of the cleansing cream of comparative example 5 were inferior to those of example 2 and also inferior to those of comparative example 4, and it can be shown that the use feeling of the cleansing cream was improved by adding 0.1 to 5% of the oil ester to the cleansing cream of the present invention, although inferior to example 2 but higher than that of comparative example 4 in terms of adhesiveness and adherence, but when the amount of the oil ester was too large, the moisturizing property and spreadability of the cleansing cream were adversely affected.

In conclusion, the facial cleanser disclosed by the invention is reasonable in component and proportion arrangement, good in experience feeling after use and excellent in moisturizing feeling of skin after use.

4. Stability test

In order to test the stability of the cleansing milk, the cleansing milks of examples 1 to 2, comparative examples 1 to 2 and comparative examples 4 to 5 were selected, left at 45 ℃ for 1 to 8 weeks, and then the separation of the cleansing milks was observed, and the results are shown in Table 5.

TABLE 5 stability of the facial washes

In table 5, the results are stable as "o", partially separated as "Δ", and completely separated as "X".

As can be seen from Table 5 above, the separation did not occur in any of the facial cleansers of examples 1-2 after 8 weeks, whereas in comparative examples 1-2, partial separation occurred at 8 th week, partial separation occurred at 4 th week in the facial cleanser of comparative example 4, and complete separation occurred at 4 th week in the facial cleanser of comparative example 5.

This is because, in comparative example 5, 10% of the oil ester was added, which is more than 0.1 to 5% of the present invention. The facial cleanser of comparative example 5 is completely separated in the fourth week due to the fact that the facial cleanser is easy to separate due to the fact that the content of the grease is high; in the other comparative examples, the added oil ester was within the range of the present invention, but the stability was inferior to that of examples 1-2 depending on the added surfactant. Therefore, the components and the proportion in the facial cleanser are reasonably arranged, and the obtained facial cleanser has good stability and long storage time.

In conclusion, the cleansing milks of examples 1 to 5 of the present invention are superior to those of comparative examples 1 to 5 in terms of cleaning ability, foaming ability, feeling of use, stability, and the like.
