					Comparative example 1 mean value/MMV	35.72	52.13	52.48	51.99
Example 1 mean value/MMV	35.84	53.21	56.22	56.06
					Comparative example 1 moisture content increase/MMV	0	16.41	16.76	16.27
Example 1 moisture content increase value/MMV	0	17.37	20.38	20.22

As can be seen from tables 3 and 4 and fig. 1 and 2, the subjects coated the samples of example 1 and comparative example 1, and the moisture content of the arm cuticle was significantly improved, but the moisturizing effect of example 1 was more significant than that of comparative example 1.

1.2, example 1 and comparative example 1 the corrosion protection challenge test results are shown in tables 5 and 6.

Table 5 corrosion challenge test results for comparative example 1 sample

Table 6 corrosion challenge test results for the sample of example 1

As can be seen from the results of tables 5 and 6, the samples of example 1 and comparative example 1 both passed the preservation challenge test. But the anticorrosive effect of example 1 is superior to that of comparative example 1.

And (4) conclusion: comparative example 1 lacks erythritol, but contains sunflower seed oil and propolis extract, and is inferior to example 1 in both moisturizing effect and preservative effect. Therefore, the erythritol has certain moisturizing and antiseptic effects.

2. Example 1 and comparative example 2

2.1, example 1 and comparative example 2 moisturizing Effect test results

The moisture content of the medial horny layer of the left and right forearms was measured by randomly selecting 10 subjects for the test using the sample of comparative example 2 for the left arm and example 1 for the right arm, and the results are shown in tables 7 and 8.

The average value of the moisture content in the inner left arm and the average value of the moisture content in the inner right arm of 10 subjects and the increase value thereof were obtained from the data, and are shown in fig. 3 and fig. 4.
