Test example 1

The test example of the application provides the sensory performance tests of the products of examples 1 to 7 and comparative examples 1 to 5, including freshness, irritation and cleaning power, and the specific method comprises the following steps:

50 women are selected, the age of the women is 30 +/-10 years, lip glaze products with the same amount are coated on the lips, mascara products with the same amount are coated on the eyes, and then makeup removing products with the same amount in examples 1-7 and comparative examples 1-5 are added on makeup removing cotton. The testers evaluated the skin feel and effect according to the makeup removal process and the makeup removed. The testers score according to the scoring standard, and finally count all the scores to calculate the average value, and the results of the scores of the freshness, the irritation and the cleaning power of the products of examples 1-7 and comparative examples 1-5 are shown in table 2.

TABLE 2 freshness, irritation and detergency scores for the products of examples 1-7 and comparative examples 1-5

Table 2 shows that the products of examples 1-7 have high refreshing degree, irritation and cleaning power scores; in the case of the same total amount of the composition, compared with the product prepared in example 1, the product has different degrees of defects in the freshness, irritation and cleaning power after the coconut oil alcohol-caprylate/caprate is replaced by the glyceryl behenate/eicosanoate in comparative example 1, the C9-C12 alkane is replaced by the isomeric hexadecane in comparative example 2, the C13-15 alkane is replaced by the palm oil in comparative example 3, and the composition ingredients are completely replaced by the cyclopentasimethicone in comparative example 4.

Comparative example 5 is a commercially available perfect diary amino acid instantaneous cleansing lip makeup remover, which does not contain any component of the composition, and does not have the same refreshing degree, irritation and cleansing power performance as those of example 1 after use, compared to example 1.

Test example 2

The test examples of the application provide the effects of the products of the above examples 1 to 7 and comparative examples 1 to 5, including the degree of cleanliness and the makeup dissolving effect. The test method is as follows: :

(1) 50 women were selected, age 30 + -10 years. Firstly, respectively smearing lipstick and mascara on the inner side of an arm, and measuring an initial color value by using a spectrophotometer after the product is aired for 15 minutes;

(2) respectively taking the same amount of products prepared in the examples 1-7 and the comparative examples 1-5 by using makeup removing cotton, applying the products to an area where a makeup product is applied, and opening the products after waiting for 15 seconds;

(3) continuing waiting for 15 minutes, waiting for the makeup removing product of arm to remain to dry, measuring the color value with the color difference meter, and calculating the difference average value of the two color values measured by the color difference meter. As shown in fig. 1 and fig. 2, fig. 1 is a comparison graph of the makeup dissolving effect of the products of example 1 and comparative examples 4 and 5 on lip glaze; fig. 2 is a comparative graph of makeup dissolving effect of the products of example 1 and comparative examples 4 and 5 of the present application on mascara.

The results of the cleanliness tests of the products of examples 1 to 7 and comparative examples 1 to 5 are shown in table 3 (p <0.001), wherein the Δ L value represents the difference in skin brightness before and after makeup removal, and the larger the measured value, the brighter and whiter the skin complexion and the more thorough makeup removal; the value of delta a indicates the red-green value of the skin color, the smaller the measured value is, the skin color is not red, the more red the skin is stimulated, and the smaller the value of delta a is, the less stimulation is. The makeup dissolving effect of the products prepared in example 1 and comparative examples 4 to 5 is shown in fig. 1 and 2.

TABLE 3 cleaning degree test results for the products of examples 1-7 and comparative examples 1-5

Table 3 shows that the products of examples 1-7 have both high cleaning power and low irritation. Compared with the products of examples 1 to 7 and comparative examples 1 to 5, the increase value of the skin brightness and the decrease value of the skin color red-green value after use are lower, which shows that the product of example 1 has stronger cleaning force and less irritation after use.

Fig. 1-2 show that, compared to example 1, comparative example 4 has substantially no make-up dissolving effect when only cyclopentadimethylsiloxane is used to prepare the product, and comparative example 5 has poor make-up dissolving effect when the product is sold on the market, which indicates that the composition of the present application has stronger cleaning effect when used in a make-up removing product with a specific content.

The above experimental results show that the composition of the application can bring fresh skin feeling to the skin and has excellent cleaning ability by using the C9-C12 alkane, the C13-C15 alkane and the coco-caprylate/caprate in a specific amount, has high biological safety, can effectively remove various oils in and on the skin, also prevents the loss of skin moisture, and has the characteristics of being fresh, strong in makeup removing ability, mild and non-irritant.
