[0033] Water phase process: sodium hyaluronate, carbomer, vitamin E and water are put into an emulsifier, heated to 85°C, homogenized and dispersed at 3000rpm for 4 minutes, and kept warm for 20 minutes to obtain preform B;

[0034] Emulsification process: slowly add preform A into preform B, stirring while adding, stirring speed 3000rpm for homogenization and dispersion for 5 minutes, keep warm for 20 minutes under stirring to form colostrum;

[0035] Cooling process: Cool the colostrum to 45°C, add phenoxyethanol, and stir evenly to obtain peony seed oil body lotion.

[0036] The raw material composition of body lotion is shown in the following table:

[0037]

[0038] Note: “-” means no addition

[0039] 1.2 Use the following test method to perform performance test on body lotion samples

[0040] 30 female volunteers aged 25-35 years old and weighing 50-70 kg were selected and randomly divided into 3 groups, namely, Example 1, Comparative Example 1 and Blank 1, with 10 people in each group. Among them, the lower abdomen was coated with 0.05 g / cm2 of film once in the morning and evening; a normal and balanced diet was taken during the use period, and the use was continued for 6 weeks. The skin elasticity of the lower abdomen before and after taking the anti-wrinkle product was tested using the German CK company's skin elasticity tester MPA580, and the R2 value was recorded (R2 value refers to: the ratio of the rebound amount of the skin without negative pressure to the maximum stretching amount when there is negative pressure. The ratio is about 1, indicating that the skin elasticity is better).

[0041] The results are shown in the following table:

[0042]

[0043] It can be seen from the above table that the body lotion prepared by the method of Example 1 has a good effect of tightening the skin and increasing elasticity;

[0044] By comparing Example 1 with Comparative Example 1, it can be seen that the body lotion using tea tree seed oil in Comparative Example 1 is not as good as that in Example 1;

[0045] By comparing Example 1 with the blank group, it can be seen that the body lotion using only peony seed oil has little effect on skin elasticity.

[0046] 2.1 Effect of the extract on the performance of peony seed oil body lotion

[0047] (1) Preparation method of peony seed oil body lotion: refer to step 1.1, wherein the extract described in the following table is used to replace the extract in Example 2.

[0048] The raw materials of the extract are shown in the following table:

[0049]

[0050] Note: “-” means no addition

[0051] (2) The performance of the peony seed oil body lotion sample was tested using the following test method

[0052] Referring to "T / SHRH015-2018 Cosmetics-Tyrosinase Activity Inhibition Experimental Method", the tyrosinase activity inhibition rate of the body lotions prepared in Examples 3-5 and Comparative Examples 1-4 was tested to evaluate their whitening effects;

[0053] 1.5 g / l of levodopa was prepared with 0.01 mol / l sodium hydrogen phosphate-citric acid buffer at pH 6.8 as substrate, 40 μL was added to the well plate, and then 80 μL of sodium hydrogen phosphate-citric acid buffer and 40 μL of the test substance (the peony seed oil body lotion sample prepared in Example 1-2 and Comparative Example 2-3) were added. Then 40 μL of 100 U / ml tyrosinase was added, mixed and reacted in a 30°C water bath for 30 minutes, and the absorbance was measured at 490 nm using a DR6000 UV-visible spectrophotometer. The tyrosinase activity inhibition rate was calculated;

[0054] Inhibition rate = [1-(T-T0) / (C-C0)]×100%, where C is the absorbance when enzyme is added but no sample is added (the absorbance value of the reaction between enzyme and substrate), C0 is the absorbance when no enzyme and no sample are added (the background absorbance value of the solvent), T is the absorbance when enzyme and sample are added (the absorbance value of the sample tube), and T0 is the absorbance when no enzyme is added but sample is added (the background absorbance value of the sample).

[0055] The results are shown in the following table:

[0056]

[0057] It can be seen from the above table that Example 1 has the best whitening effect, Example 2 has a slightly inferior whitening effect to Example 1, and the whitening effects of Comparative Examples 2 and 3 are not as good as Example 2.

[0058] 3.1 Test the effect of adding different concentrations of peony oil to body lotion on skin water loss rate. The results are shown in Figure 1 ; The body milk prepared by the method of Example 1 was tested using a Zeta potential analyzer, and the results are shown in Figure 2 .

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
