The safety test results are shown in table 1:
as can be seen from table 1, the skin grades of all subjects at 0.5, 6, 12, 24 and 48 hours were 0 grade, i.e. the skin reactions were all negative, which indicates that the whitening and freckle-removing essential oils prepared in examples 1 to 4 of the present invention were safe to use and that the whitening and freckle-removing essential oils prepared in comparative examples 1 to 4 occasionally showed allergic reactions, as per the patch test of each group of whitening and freckle-removing essential oil samples.
Whitening and freckle-removing efficacy test
Melanin reduction rate test: 40 volunteers, age 20-50 years old, men and women are not limited, skin melanin reduction rate test is carried out, the tested human group is divided into 8 groups, each group of 5 people, 8 groups of subjects are respectively smeared with whitening and spot-lightening essential oil of examples 1-4 and comparative examples 1-4, before the subjects are smeared with the whitening and spot-lightening essential oil for the first time, the stratum corneum cells of the skin of the subjects are taken by scraping blades and are preserved for standby, after the whitening and spot-lightening essential oil is smeared for 28 days, the stratum corneum cells of the same subject are taken at the same position, then the stratum corneum cells scraped for the first time and the second time are respectively dyed by using melanin staining liquid, the melanin content is visualized, and then the skin images of the subjects are subjected to data analysis, so that melanin semi-quantitative analysis results are obtained, and the test results are shown in table 1.
Tyrosinase inhibition assay: 0.03g of each of the whitening and spot-lightening essential oils of examples 1 to 4 and comparative examples 1 to 4 was taken, and 150. Mu.L of a phosphate buffer solution having a pH of 6.8, 0.1mol/L and 50. Mu.L of an L-tyrosine solution having a concentration of 3mmol/L were added thereto, respectively; respectively taking 8 mixed samples, loading the mixed samples into a 96-well plate, adding 60 mu L of tyrosinase solution with enzyme activity of 100U/mL into each well at a constant temperature of 37 ℃, uniformly mixing, placing the 96-well plate into a multifunctional micro-pore plate detector after water bath for a period of time at 37 ℃, measuring absorbance value at 475nm, calculating tyrosinase inhibition rate, repeating the above operation, carrying out parallel measurement for 3 times, taking an average value, and recording in Table 2.
DPPH clearance test: taking 1.0g of each of the whitening and spot-lightening essential oil samples of examples 1-4 and comparative examples 1-4, adding 2.0mL of 0.05mg/mL DPPH methanol solution, fully mixing, taking the solvent as a blank control, and measuring absorbance A1 at 517 nm; the same volume of solvent is used for replacing the whitening and freckle-removing essential oil sample solution to be used as negative control, and the absorbance A2 is measured; the same volume of methanol was used as a blank group instead of DPPH solution, absorbance A3 was measured, each group was repeatedly measured 3 times, the average value was calculated, the test results are shown in Table 2, and the DPPH clearance was calculated as follows:
clearance (%) = [1- (A1-A3)/A2 ] ×100% of DPPH
