The oil control loose powder obtained in examples 1 to 10 and comparative examples 1 to 3 was subjected to a long-acting oil control test, and the specific test method was:

130 female oil skins and female mixed oil skins which are 20 to 30 years old and have daily makeup habits are selected as healthy volunteers and randomly divided into 13 groups, 10 people in each group are made up and tested according to the normal makeup habits of the face, the grease secretion amounts of the initial makeup, 4 hours and 8 hours are tested by using a Cutomer dual MPA 580 instrument, and the specific test results are shown in a table 1.

TABLE 1 Long-term oil control test results (unit: μ g/cm)²)

	Example 1	Example 2	Example 3	Example 4	Example 5	Example 6	Example 7
								First-time makeup	7.20	8.21	7.48	8.34	7.13	8.34	8.31
4 hours	87.66	81.56	83.84	88.46	96.90	95.30	96.32
								8 hours	174.84	178.90	173.76	183.22	187.60	185.48	188.50
	Example 8	Example 9	Example 10	Comparative example 1	Comparative example 2	Comparative example 3
								First-time makeup	7.90	8.22	8.52	15.78	12.13	13.20
4 hours	100.80	96.78	92.60	165.91	112.66	128.70
								8 hours	180.60	183.3	184.66	230.66	210.90	203.90

As can be seen from the test results in table 1, the long-acting oil control composition of the present invention is added, so that the examples 1 to 10 can achieve effective oil absorption and oil control from the initial makeup, while the facial oil secretion amount of the examples 1 to 10 is much lower than that of the comparative examples 1 to 3 with the increase of the makeup duration, because the fullerene is slowly released to restore the internal space of the porous silica, so that the newly secreted oil can be continuously absorbed to achieve the long-acting oil control, while for the comparative examples 1 to 3, the oil is adsorbed by the silica and fills the adsorbed space of the silica in the initial makeup, so that the oil can not be effectively controlled in the subsequent makeup duration.

Experimental example 3 cosmetic effect test

The make-up holding effect test of the oil control loose powder obtained in the examples 1 to 10 and the comparative examples 1 to 3 is carried out, and the specific test method comprises the following steps:

130 women with the oil skin and the mixed oil skin, which are 20 to 30 years old and have daily makeup habits, are selected as healthy volunteers and randomly divided into 13 groups, 10 people in each group are made up and tested according to the normal makeup habit of the face, a spectrophotometer is used for testing the brightness L of the initial makeup, 4 hours and 8 hours and calculating the change value delta L of the brightness, and the specific test result is shown in table 2.

Table 2 cosmetic results

As can be seen from the test results of table 2, the brightness of examples 1 to 10 decreased less with increasing makeup duration due to the addition of the long-acting oil-controlling composition of the present invention, at around 1, while the brightness of comparative examples 1 to 3, to which no long-acting oil-controlling composition was added, decreased more. The reason is that the anti-oxidation component fullerene is added into the long-acting oil control composition, so that the fullerene can be slowly released from the porous silica in the make-up process, the long-acting anti-oxidation effect is achieved, the phenomenon that the fullerene is completely exposed to air and loses efficacy when the make-up is carried out for the first time is avoided, and meanwhile, the rest oil-absorbing components are matched to adsorb sebum, so that the make-up is prevented from being oxidized and hidden after a large amount of oil is discharged.

The cosmetic effect satisfaction degree crowd test is carried out on the oil-control loose powder obtained in the examples 1 to 10 and the comparative examples 1 to 3, and the specific test method comprises the following steps:

390 female oily skins and female mixed oily skins which are 20 to 30 years old and have daily makeup habits are selected as healthy volunteers and randomly divided into 13 groups, each group of 30 female oily skins are tried out according to the normal makeup habit of the face and filled in an questionnaire, and the effects of the makeup fitting degree, the oil control degree, whether the skin is pulled dry, dark and the like after the initial makeup, 4 hours and 8 hours are graded according to the satisfaction degree of 1-5, wherein 1 is very unsatisfactory, 2 is unsatisfactory, 3 is general, 4 is satisfactory, 5 is very satisfactory, and the specific test result is shown in a table 3.

Table 3 cosmetic effect satisfaction degree crowd test results

As can be seen from the test results in table 3, the scores of the degree of compliance, the degree of oil control, the skin dryness-free property and the darkness-free property of the oil-control loose powder of examples 1 to 10 are all higher than those of comparative examples 1 to 3, because the long-acting oil-control composition, the skin feel modifier, the filler and the emollient of examples 1 to 10 form a mutually matched system under a reasonable proportion, so that the loose powder has soft skin feel and excellent skin-friendly property and is more suitable for the skin while resisting the dark deposit and continuously controlling the oil without dryness-free property.
