Comparative example 1
Deionized water
Comparative example 2
A certain brand of essence milk (active ingredient: rose hydrosol) is sold in the market.
For the safety test of the example 1 and the comparative example 1, referring to the method for testing the closed type spot pasting of the human skin of the fifth part of cosmetic safety technical Specification (2015 edition), 30 volunteers are selected, the samples of the example 1 and the comparative example 1 (deionized water) are synchronously tested for the closed type spot pasting, and the allergic phenomena such as redness of the skin or erythema are not seen (see Table 1), so that the essence emulsion prepared in the example 1 is safe and does not cause any adverse phenomenon.
Table 1 closed patch test results
Example 1 Comparative example 1
Skin redness or erythema and other allergic phenomena Has no redness and allergy Has no redness and allergy
The moisturizing effect test (3 h) was performed on example 1 and comparative example 2, and 20 testers were selected for each sample, and the samples of example 1 and comparative example 2 were quantitatively applied to forearm-contoured portions, referring to the QB/T4256-2011 cosmetic moisturizing efficacy evaluation guidelines. The values of the water and oil contents of the skin horny layer and the percutaneous water loss rate before using the sample (initial value of the sample was not used), 0h after using (initial value of the sample was used, and the test was performed after beating for 10 seconds after wiping) 1h, 3h were measured using an instrument MOISTUREMETERSC MSC1212 (DELFIN) and an instrument tapomete SWL5167 (DELFIN), respectively, and the obtained values were recorded and the average value was calculated, and the results are shown in table 2.
TABLE 2 Water oil content of the stratum corneum of skin
The test results showed that the initial value (0 h) of the used sample of example 1 was increased from 34% to 70% and the moisture content was increased approximately 2.06 times, and that the moisture content of comparative example 2 was increased from 36% to 63% and the moisture content was increased 1.75 times, respectively, compared with the moisture content of comparative example 2 before the use (before the use), which showed that the increase in the initial moisture content of example 1 was more remarkable than that of comparative example 2.
The oil content of example 1 was reduced from 51% to 38%, the reduction was 13%, the reduction was 40% from 50% to comparative example 2, and the reduction was 10%, which indicated that the oil content of example 1 was reduced more than that of comparative example 2 at the initial stage of use.
The water and oil contents of the skin are detected in the test 1h and the test 3h respectively, the result shows that the water content and the oil content of the product of the example 1 are 47% after the test 1h, the water and oil balance is achieved, the water content and the oil content are 45% and 47% after the test 3h respectively, the water and oil balance is basically achieved after the product of the example 1 is used for 3h compared with the water and oil proportion of the product of the example 1 before the use, and the result shows that the product of the example 1 can still ensure the water and oil balance of the skin after the product is used for 3h, and the moisturizing effect is obvious; and the water and oil contents of the comparative example 2 after the test for 1h are 38% and 50%, respectively, and the water and oil contents after the test for 3h are 38% and 49%, respectively, and the water and oil ratio is restored to the water and oil ratio before the use, and the result shows that the comparative example 2 becomes non-moisturizing effect after the use for 1 h.
The stability and safety test was carried out on the essence emulsion of example 1, and the results are shown in table 3, and the essence emulsion has no obvious change in appearance, smell, pH value and storage stability in freeze thawing cycle and heat/cold resistance test.
TABLE 3 results of test for storage stability of essence milk
