Test one: cleaning ability test

Test samples: the tests of examples 1 to 17 and comparative examples 1 to 7 were carried out.

Test subjects: XX white collar skin of 18-35 years old sensitive skin in the same area is selected as a subject, and is averagely divided into X groups which are 1-X groups respectively.

The test method comprises the following steps: the face of each subject was coated with the same area of the same color of Dior, the same mascara of Paeonia lactiflora, and the same eyebrow powder of innisfree. Wherein the subjects of groups 1-17 were cleaned using examples 1-17, respectively, and the subjects of groups 18-X were cleaned using comparative examples 1-7, respectively, and gently cleaned for 25 seconds for each of the parts coated with lipstick, mascara, and eyebrow powder, the foam on the face was rinsed with water, and traces of three different cosmetics remaining on the face were observed, recorded, and analyzed.

And (3) test results: the cleaning abilities of examples 1 to 17 and comparative examples 1 to 7 are shown in Table 7.

TABLE 7 ability to clean examples 1-17, comparative examples 1-7

As can be seen from Table 7, when the cleaning is performed by using examples 1-17, lipstick, mascara and eyebrow powder can be cleaned, but when the cleaning is performed by using comparative examples 1-7, lipstick, mascara and eyebrow powder have different residual degrees, and especially mascara is difficult to clean.

Comparing examples 1-17 with comparative examples 1-2 and comparative example 7, it is demonstrated that the bar-shaped cleansing product has a firmer, denser, but more uniform texture than a cream, and can provide a better massaging effect on the skin when cleansing the skin, but the fine texture is less likely to cause damage to the skin, thereby achieving a better cleansing effect, and also enabling the skin to maintain a better comfort, moisturize and be less tense.

Comparing examples 1-17 with comparative examples 3-6, it is demonstrated that the combination of surfactant, C12-15 alkanol benzoate, and skin conditioning agent can provide a cleanser with better cleansing ability, less tendency to produce a tight feeling, and help to maintain good moisturizing and emollient effects on the skin.

And (2) test II: experience test

Test samples: examples 1 to 17 and comparative examples 1, 2 and 7 were selected as test samples.

Test subjects: 200 white collars of the same region and age range of 18-35 years, similar to face skin acne and comedo, were selected as subjects, and were divided into 20 groups, 1-20 groups respectively.

The test method comprises the following steps: the facial skin was cleaned each morning and evening before bedtime using the cleansing method of test one, and after 3 months of continuous use, the facial condition of each group of subjects was observed, recorded and analyzed.

And (3) test results: after three months of continuous use of examples 1-17, comparative examples 1, 2, and 7, the facial condition of the corresponding group of subjects is shown in table 8.

TABLE 8 face condition of each group of subjects after three months of continuous use of examples 1-17, comparative examples 1, 2, and 7

Group number	Facial condition of the subject
		Group 1	Acne and comedo disappear, and acne marks are obviously faded
Group 2	Acne and comedo disappear, and acne marks are obviously faded
		Group 3	Acne and comedo disappear, and acne marks are obviously faded
Group 4	Acne and comedo disappear, and acne marks are obviously faded
		Group 5	Acne and comedo disappear, and acne marks are obviously faded
Group 6	Acne and comedo disappear, and acne marks are obviously faded
		Group 7	Acne and comedo disappear, and acne marks are obviously faded
Group 8	Acne and comedo disappear, and acne marks are obviously faded
		Group 9	Acne and comedo disappear, and acne marks are obviously faded
Group 10	Acne and comedo disappear, and acne marks are obviously faded
		Group 11	Acne and comedo disappear, and acne marks are obviously faded
Group 12	Acne and comedo disappear, and acne marks are obviously faded
		Group 13	Acne and comedo disappear, and acne marks are obviously faded
Group 14	Acne and comedo disappear, and acne marks are obviously faded
		Group 15	Acne and comedo disappear, and acne marks are obviously faded
Group 16	Acne and comedo disappear, and acne marks are obviously faded
		Group 17	Acne and comedo disappear, and acne marks are obviously faded
Group 18	Slight acne and comedo fading, obvious acne mark
		Group 19	Slight acne and comedo fading, obvious acne mark
Group 20	Almost 3 months ago without change

As can be seen from Table 8, after the corresponding test samples of different groups are continuously used for three months, the face of the testees of groups 1 to 17 has no pockmarks and comedones which originally have grown on the face, and the existing pockmarks are obviously lightened; in the subjects in groups 18 to 19, although the acne and comedones were slightly reduced, the acne marks were obvious; whereas in the subjects of group 20, the original long pox and comedones were not eliminated.

Comparing the test results of the groups 1-17, 18-19 and 20, it is shown that the texture of the test sample has a great influence on the skin cleansing effect, and the facial cleanser with a relatively hard pasty texture can not only massage the skin, help to open pores in the skin, and achieve a deeper cleansing effect, but also control the phenomena of acne and comedo well and remove acne and comedo during the cleansing process of the facial skin. The skin conditioner, the C12-15 alkanol benzoate phase and the surfactant in the examples 1-17 are fully mixed, so that the skin conditioner has a good moisturizing effect on the skin, the acne mark part can be well repaired, and the acne mark fading effect is achieved.
