Background
Skin whitening is a permanent topic and pursuit of vast women who love beauty. The research and development, safety and efficacy evaluation of whitening skin care products naturally become the focus of attention of researchers, production operators and consumers. The color of the skin is mainly determined by the skin pigment content and distribution, with melanin being the most dominant determinant. Melanocytes in the skin produce melanin, melanin granules are transferred to keratinocytes through melanocyte dendrites, and the melanin granules transferred to the keratinocytes ascend to the stratum corneum along with epidermal cells, thereby affecting the color of the skin or forming color spots, and finally being excreted along with the shedding of the stratum corneum.
In addition, the irradiation of ultraviolet rays also changes melanin to generate a substance for protecting the skin, and then the melanin moves layer by layer through cell metabolism to reach the skin epidermis, so that the skin problems such as color spots, uneven skin color and the like seen by people are formed.
At present, the general skin whitening agent mainly inhibits the activity of tyrosinase in the skin through alpha-arbutin, blocks the formation of melanin, and accelerates the decomposition and excretion of the melanin through the direct combination of the alpha-arbutin and the tyrosinase, thereby reducing the pigmentation of the skin and removing stains and freckles. However, as the demand for whitening effects by beauty-conscious people becomes higher, the whitening agent prepared only from α -arbutin has not been able to satisfy the demand for whitening effects by beauty-conscious people, and thus how to provide a whitening composition having a remarkable whitening effect is a technical problem that needs to be solved.

test of whitening Effect
(1) Taking the example and comparative example cosmetics;
(2) the test population: 90 testers with average age of 25-35 years; wherein, 35 men and 65 women have no damage to skin health; each example and comparative example had 15 subjects. Selecting the left and right cheekbones of the face of a subject, the left and right cheeks at the intersection of the nose tip and the pupil, and the left and right sides at the intersection of the temple and the mouth corner as test areas;
(3) firstly, a blank value of an experimental part before the cosmetic is applied is measured by a technician by using a skin melanin tester (Mexa meter MX 18) of Germany CK company, five times are measured at each point, and an average value is taken;
(4) the subjects measured the data of the experimental sites using a skin melanin tester (Mexamete r MX 18) five times per spot, and averaged once a day, morning and night, after one, two, three, and four consecutive weeks using the example and comparative cosmetics;
(5) and (4) counting the average value of the values measured at each time of the experimental part of the subject, and analyzing the change rule of the MI value, thereby determining the whitening efficacy of the cosmetics of the examples and the comparative examples.
Test data: after four weeks (28 days) of use of the product, the statistics are shown in table 2:
