Experimental example

1. Cleaning ability test

To test the cleansing power of the facial cleanser of examples 1-5 and comparative examples 1-5, 10 test persons were randomly selected and divided into 10 groups. Lipstick and BB cream were applied to a 2 cm area of the arm. The skin was then left to be exposed for 15 minutes at room temperature. After 15 minutes, the facial cleanser of examples 1 to 5 and comparative examples 1 to 5 was applied to the cosmetic skin, rubbed by hand for 25 times, rinsed with flowing warm water, and rubbed by rolling for another 10 times. After the moisture on the skin surface was removed gently, the makeup removing ability was judged by visual comparison. Counting the cleaning ability scores of each group of facial cleanser according to the following scoring rules;

(1) The total erasure is 10 minutes;

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

The cleaning ability score statistics for each group of facial washes are shown in table 2.

Table 2 cleaning ability of the facial cleanser of examples 1-10 and comparative examples 1-5

Example 1	Example 2	Example 3	Example 4	Example 5
					Cleaning power (minutes)	7	8	7	8	8
Comparative example 1	Comparative example 2	Comparative example 3	Comparative example 4	Comparative example 5
					Cleaning power (minutes)	3	6	5	5	2

As can be seen from Table 2, the cleansing bars of examples 1 to 5 were strong in cleansing power and the cleansing bar score was 7 or more, indicating that the cleansing bars of examples 1 to 5 had a certain cleansing and cleansing power for makeup. In comparative examples 1 to 5, the cleaning power was significantly inferior to that of examples 1 to 5, and the cleaning power score was around 2 to 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 of examples 1 to 5, such as the anionic surfactant is single potassium cocoyl glycinate, the zwitterionic surfactant is single sodium dodecyl phosphate, the nonionic surfactant is single PEG-80 sorbitol laurate, and the detergency score thereof is 3, indicating that the use of single anionic surfactant, single zwitterionic surfactant and single nonionic surfactant, the detergency of the facial cleanser is lowered under the other conditions; the components in the composite surfactant are synergistic, so that the cleansing and cleansing capabilities of the make-up remover are improved.

In comparative example 2, only potassium cocoyl glycinate was used as the anionic surfactant, which was the same as the surface-active component; also, in comparative example 3, only sodium dodecyl phosphate was used as the zwitterionic surfactant; in comparative example 4, only PEG-80 sorbitol laurate was used as a nonionic surfactant, and it can be seen from the data in Table 2 that the cleansing power of comparative examples 2-4 was improved but was inferior to that of examples 1-5, indicating that the surfactant groups were synergistic in the present application, and the lack of any one of them affected the cleansing power and the cleansing ability of the facial cleanser. In comparative example 5, the amount of the added oil ester is 10% by mass, exceeding 0.5 to 5% required in the present application, and the cleansing power and cleansing ability thereof are drastically reduced by only 2, because the amount of the oil ester is excessive, the contact of the surfactant with the skin is reduced during the cleansing process, the activity of the surfactant is lowered, and thus the cleansing ability of the facial cleanser is affected.

2. Foaming force test of facial cleanser

3g of the facial cleanser of examples 1-5 and comparative examples 1-5 were taken on a non-wet hand by a hand beating method, then 30g of water at 25 ℃ was added, after 50 times of foaming by kneading with hands, the volumes of the foams produced were compared, namely, the foams were transferred to a measuring cup, the volumes of the foams were tested, and the foaming capacity of the facial cleanser was judged by comparing the volumes of the foams, and specific scoring criteria are as follows: the foam volume was greater than 10mL, 10 minutes, 9-10mL, 9 minutes, 8-9mL, 8 minutes, and so on, less than 1mL, 0 minutes, and the results of the statistics of examples 1-5 and comparative examples 1-5 are shown in Table 3.

TABLE 3 foaming Capacity of facial cleanser of examples 1-5 and comparative examples 1-5

Example 1	Example 2	Example 3	Example 4	Example 5
					Foaming force (minutes)	7	8	7	8	9
Comparative example 1	Comparative example 2	Comparative example 3	Comparative example 4	Comparative example 5
					Foaming force (minutes)	3	6	5	5	2

As can be seen from Table 3, examples 1 to 5 had a foamability score of 7 or more, whereas comparative examples 1 to 5 had a foamability score of about 2 to 6, and the foamability of examples 1 to 5 was superior to that of comparative examples 1 to 5. Specifically, since in examples 1 to 5, a plurality of kinds of surfactants were compounded together as surfactants for the facial cleanser, whereas in comparative examples 1 to 4, the surfactants for each group of facial cleanser were single components, resulting in poor foaming ability of the facial cleanser; it is also stated that in the present application, the various surface activities in the facial cleanser are synergistic and that the synergistic effect is not simply additive but rather provides a great degree of lathering ability.

3. Usability assessment

30 women were randomly selected, aged 20-30 years, and were divided into 3 groups of 10, and the facial washes of example 2, comparative examples 4 and 5 were used by the users of each group, and after 4 weeks of continuous use, the users were compared for application feeling of the facial washes, adhesion, tackiness, moisturizing feeling, and the corresponding scores were obtained, and the results are shown in table 4. Among them, the user feels very good 5 points, good 4 points, generally 3 points, 2 points, very 1 point.

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

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

As can be seen from Table 4 above, the use feeling of the facial cleanser of example 2 for diffusion, adhesion, etc. was better than those of comparative examples 4 and 5. This is because, in comparative example 4, the nonionic surface activity used was 12% PEG-80 sorbitol laurate, whereas in example 2 the nonionic surface activity was a mixture of three; the viscosity of the facial cleanser of comparative example 2 was inferior to that of the facial cleanser of example 2, and the negative force of the facial cleanser of comparative example 4 was also inferior to that of example 2; comparative example 4 is better than comparative example 5 in terms of moisture retention and diffusivity, but is also worse than example 2; from this, it can be demonstrated that the composition of the nonionic surfactant directly affects the viscosity and adhesion of the facial cleanser, and has little effect on the moisture retention and diffusivity.

In comparative example 5, the added oil ester was 10%, which was 0.1 to 5% in excess of that in the present application. The difference in the moisture retention and the diffusivity of the facial cleanser of comparative example 5 was compared with those of example 2 and also compared with those of comparative example 4, but the difference in the viscosity and the adhesion was compared with those of example 2 but was higher than those of comparative example 4, so that it was revealed that the use feeling of the facial cleanser was improved by adding 0.1 to 5% of the oil ester to the facial cleanser of the present application, but the moisture retention and the diffusivity of the facial cleanser were adversely affected when the oil ester was too much.

In conclusion, the facial cleanser disclosed by the application is reasonable in component and proportion, good in experience after use and excellent in moisturizing effect on skin after use.

4. Stability test

To test the stability of the facial cleanser, the facial cleanser of examples 1-2, comparative examples 1-2 and comparative examples 4-5 was selected, left at 45℃for 1-8 weeks, and then the separation of the facial cleanser was observed, and the results are shown in Table 5.

Table 5 stability Properties of the facial cleanser groups

In Table 5, the stability was "O", the partial separation was "delta", and the complete separation was "X".

As can be seen from Table 5 above, the facial cleanser of example 1-2 did not separate after 8 weeks, whereas in comparative example 1-2, partial separation occurred at 8, the facial cleanser of comparative example 4 did separate partially at 4 weeks, and the facial cleanser of comparative example 5 did separate completely at 4 weeks.

This is because, in comparative example 5, the added oil ester was 10%, which is more than 0.1 to 5% in the present application. The facial cleanser is more likely to separate during storage, so that the facial cleanser of comparative example 5 is completely separated in the fourth week; in other comparative examples, however, the added oil ester was within the scope of the present application, but the stability was also inferior to examples 1-2 due to the different surfactants added. Therefore, the components and the proportion in the facial cleanser are reasonable, and the obtained facial cleanser has good stability and long storage time.

As described above, the facial cleanser of examples 1 to 5 of the present application was superior to the facial cleanser of comparative examples 1 to 5 in terms of cleaning ability, air bubble ability, feeling in use, stability, etc.

The embodiments described above are some, but not all embodiments of the application. The detailed description of the embodiments of the application is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application.
