Firstly, evaluating the safety of products

A spot pasting method is adopted for safety test, 240 volunteers aged 20-35 years are selected as test subjects, and the skin conditions of all the volunteers are healthy and normal. 240 volunteers were randomly divided into 8 groups and used the foundations of examples 1 to 8, respectively.

The spot pasting method comprises the following steps: selecting a qualified aluminum patch device, sealing the patch method, dripping 0.020 g-0.025 g of a test object into the patch device, externally applying an imported medical special adhesive tape to the part which is not easy to touch on the arm of a test object, removing the test object within 24 hours, observing skin reactions within 0.5, 12, 24 and 48 hours after the test object is removed respectively, and recording the results according to the skin grading standard in the technical Specification for cosmetic safety 2015 edition.

The test results show that: each group of subjects observed skin reactions at 0.5, 12, 24, and 48 hours by a patch test, wherein 0 cases showed adverse skin reactions, indicating that the foundations of examples 1 to 8 were safe to use.

Second, product effect evaluation

And (3) testing a sample: the foundations of examples 1 to 8 and a conventional BB cream commercially available.

The test population: 270 volunteers are selected as subjects, the age is 20-40 years, the male-female ratio is 1:1, and the skin condition is as follows: the face has spots, dark complexion and no allergic history of the dermatosis, and the method meets the voluntary selection standard of the subject.

Grouping: 270 volunteers were divided into 9 groups at random, the ratio of male to female in each group was 1:1, the skin complexion and the number of spots of each group of volunteers were similar, and the 9 groups of volunteers used the conventional BB cream of examples 1-8 and the market, respectively.

The test method comprises the following steps: selecting T-shaped region of face, and drawing the same 9cm region and speckle part²Area (1 g) of the smear sample. The rate of change of the red melanin value [ (post-application-initial value)/initial value X100%) was measured using MexametrMX 18 (melanin and heme test probe) from the instrument Cutomer dual MPA580]The rate of change of spot number values in the smeared area of the face [ (post-initial value)/initial value x 100%) was measured using a facial image analyzer VISIA7]The skin brightness change rate [ (post-application-initial value)/initial value X100%) of the test area was measured using an x-rite color difference meter]And averaging. The test results are shown in table 2.

TABLE 2 test results

As can be seen from the results of table 2, the foundation for discoloration correction of skin color of the present invention has superior effects of concealing, lightening and regulating skin color, and can make skin color uniform and beautiful, especially the best effect of example 1, inferior to the effect of example 2.

Thirdly, in order to investigate the influence of the composition and component distribution of the coated particles on the foundation effect, 5 groups of test groups were set, and the composition and component distribution of the coated particles of each group are shown in table 3.
