Test example 2 scalp moisturizing Effect test
Experimental materials: the products of example 1 and comparative examples 1-6 were diluted to 5 times with olive oil and used as samples to compare the change in moisture content of the skin of the test subjects after the samples were used.
The test refers to the evaluation guideline of moisturizing efficacy of cosmetics in the light industry standard to test the moisturizing efficacy of the sample. The principle of the method is as follows: the capacitance method is used for measuring the moisture content of the human skin horny layer, and is based on the obvious difference of dielectric constants of water and other substances, the capacitance values of the measured skin are different according to the moisture content of the human skin horny layer, and the parameters can represent the moisture content of the scalp.
40 subjects stained with permum were selected, all subjects had no history of any scalp allergy or scalp affection, and the test sites had no abnormality. A female subject; the age is 21-45 years. The whole testing process is carried out in a constant temperature and humidity laboratory, the room temperature is 20-22 ℃, and the humidity is 40-60%. The moisture content of each experimental site was determined using a Corneometer CM825 (Courage + Khazaka, germany, available from hokkiso). The larger the value, the higher the water content of the stratum corneum. The posterior side of the head was selected as the test site (5 cm. times.5 cm). Before testing, the testee washes hair with the same shampoo, dries, and then keeps a certain body position for 30 min. Example 1 and comparative examples 1 to 6 were each separately preparedThe sample is applied to the test site. The test time points are respectively before sample application (0h), after sample application for 1h and 2 h. The sample coating amount is 2.0 +/-0.1 mg/cm2。
And then calculating the average hydration rate of the volunteers at different time intervals, and calculating the hydration rate by using a formula (1):
the results are shown in Table 4.
TABLE 4
As can be seen from Table 4, the skin of the sample of example 1 of the present invention still has a high moisture content 2 hours after application, indicating that the essential oil composition prepared by the present invention has a good moisturizing effect. The samples of comparative examples 1 to 6, however, had lower hydration rates per time period than the samples of example 1 of the present invention. Therefore, after the essential oils are scientifically combined, the moisturizing effect is improved under the condition of consistent dosage, and the essential oils have good synergistic moisturizing and synergistic effects.
