The procedure was as in example 2 except that 2, 6-di-tert-butyl-4-methylphenol and butylated hydroxyanisole were not added.

The experimental method comprises the following steps:

weighing 10g of the smooth-skinned papaya seed oil cleansing oil samples prepared in the example 1, the comparative example 8 and the comparative example 9, placing the samples in a beaker, adding 0.01% of antioxidant by mass, storing the samples for 9 days at (60 +/-1) DEG C under the condition of no air blast, detecting the peroxide value (24 h/time), repeating the experiment for 3 times, and taking an average value; determining the peroxide value of the shine skin papaya seed oil cleansing oil according to an ultraviolet spectrophotometry, and evaluating the antioxidant activity of the shine skin papaya seed oil cleansing oil;

the antioxidants of example 2, comparative example 8 and comparative example 9 were selected from a mixture (BB) of 2, 6-di-tert-butyl-4-methylphenol and butyl hydroxyanisole, vitamin E (VE) and Propyl Gallate (PG), the blank control group was a makeup removing oil of papaya seed oil without antioxidant, and according to the specifications of cosmetic safety technical specifications (GB 2760-2014), 0.02% was the maximum additive amount of 2, 6-di-tert-butyl-4-methylphenol (BHT) and Butyl Hydroxyanisole (BHA), 0.01% of propyl gallate was the maximum additive amount, and vitamin E was used in a proper amount, so the addition amounts of 3 antioxidants in the peroxide number determination experiment were all set to 0.01%, 3 different antioxidants were added to the makeup removing oil of papaya seed oil by Schaal oven method, and the effects of different antioxidants on the makeup removing oil during oxidation in a fixed time were compared.

As shown in fig. 1, fig. 1 shows the influence of three antioxidants on the antioxidant effect of the papaya seed oil cleansing oil, and the peroxide value of the papaya seed oil cleansing oil added with the 3 antioxidants is lower than that of a blank control group, which indicates that the three antioxidants have the antioxidant effect, wherein the peroxide capacity of the papaya seed oil cleansing oil is as follows: blank PG < VE < BB, and POV value of the skin-smooth papaya seed cleansing oil prepared in the example 1, the comparative example 8 and the comparative example 9 is slowly increased in 48 hours before the experiment, because the skin-smooth papaya seed oil in the cleansing oil is rich in polyphenol and flavonoid substances and plays a certain role in antioxidation, and the antioxidant in the skin-smooth papaya seed oil cleansing oil is obvious after 48 hours, wherein BB has the strongest antioxidation, so that the mixture (BB) of the 2, 6-di-tert-butyl-4-methylphenol and the butyl hydroxy anisole prepared in the example 2 is used as the antioxidant.

Comparative example 11

The procedure was as in example 1 except for replacing 0.0075g of 2, 6-di-tert-butyl-4-methylphenol and 0.005g of butylated hydroxyanisole by 0.0075g of these reactants.

Comparative example 12

The procedure was carried out in the same manner as in example 1 except that 0.0075g of 2, 6-di-tert-butyl-4-methylphenol was replaced with 0.01g, and 0.0075g of butylated hydroxyanisole was replaced with 0.01g.

Comparative example 13

The procedure was as in example 1 except that 0.0075g of 2, 6-di-tert-butyl-4-methylphenol was replaced with 0.0125g, and 0.0075g of butyl hydroxyanisole was replaced with 0.0125g.

Accurately weighing 4 parts of the papaya seed oil cleansing oil, 10g of each part, placing the weighed 4 parts in a beaker, adding 0.01%, 0.015%, 0.02% and 0.025% of BB into the 4 parts, namely the papaya seed cleansing oil prepared in the comparative example 11, the example 1, the comparative example 12 and the comparative example 13, uniformly stirring the papaya seed cleansing oil prepared in the comparative example 11, the example 1, the comparative example 12 and the comparative example 13, placing the mixture in an oven at (60 +/-1) DEG C, exchanging the positions of the papaya seed cleansing oil in the oven every day, stirring the mixture once at regular time, sampling every 24 hours to determine the peroxide value, and continuously monitoring for 7d.

FIG. 2 shows the effect of different amounts of antioxidants on peroxide value (POV), and samples No. 1, 2, 3 and 4 in FIG. 2 correspond to the makeup removing oil prepared in comparative example 11, example 1, comparative example 12 and comparative example 13, respectively, wherein the mass percentages of the mixture BB containing 2, 6-di-tert-butyl-4-methylphenol and butyl hydroxyanisole are 0.01%, 0.015%, 0.02% and 0.025%, respectively, and no BB is studied because the peroxide value (POV) is similar to the mass percentage of the mixture BB containing 2, 6-di-tert-butyl-4-methylphenol and butyl hydroxyanisole, which is 0.01%, in the absence of BB. As can be seen from figure 2, as the mass fraction of BB increases, the antioxidant effect of BB is enhanced, the BB is strongest at 0.025%, the mass fraction of BB is not greatly different from that of BB at 0.015%, the effective effect of BB at 0.01% is not obvious, and the BB at 0.015% is selected as the optimal additive amount of the papaya seed oil cleansing oil in consideration of certain irritation of BB to the skin.

In conclusion, the glabrous papaya seed oil is rich in nutrition but low in oxidation resistance, an antioxidant with good oxidation resistance needs to be selected as the base oil of the makeup remover, the oxidation resistance of the three antioxidants is compared and researched by adopting a Schaal oven method, a mixture (BB) of 2, 6-di-tert-butyl-4-methylphenol and butyl hydroxyanisole with the best oxidation resistance is selected as the antioxidant of the makeup remover, and the addition amount of the BB is determined to be 0.015%.
