Test Example 1: Moisturizing Effect

In order to determine the moisturizing effect of the skin care bath skin care composition according to the present invention, the following experiment was performed with existing skin care products.

1) Short-term moisturizing effect measurement using corneometer

In order to measure the moisturizing effect of the skin forest bath composition (SF + lotion) of the present invention obtained in Example 1, baby lotions (J & J milk ^R , NIVEA ^R , J & J bedtime ^R , J & J ultracare ^R ,) Moisturizing force measurement test was carried out together with Nuke ^R ). The test equipment used a moisture meter (corneometer, electronic GmbH, Germany).

Specifically, ten subjects were washed with running water from the wrists to the elbows of both forearms. The test site was a forearm flexion part 5 cm from the subject's wrist, and a total of 7 circles were drawn by drawing a 1 cm diameter circle for each test area (one circle is for an uncoated control group). Selected. After waiting for 30 minutes in a constant temperature and humidity room, the moisture content of the test site was measured three times with a moisture meter and the average value was obtained. Subsequently, the existing baby lotions and skin forest bath lotion samples of the present invention were applied to the test sites and absorbed well, and then the water content of the test sites was measured once again after 1 hour and 2 hours in a constant temperature and humidity room. The moisture content increase rate (%) was calculated based on the moisture content of the initial state and the results are shown in Table 5 and FIG. 1.

Moisture content increase rate (%) J & J Milk Nivea J & J Battime J & J Ultra Care Nuuk SF + Lotion Initial state 0 0 0 0 0 0 1 hour later 20 13 10 16 40 59 2 hours later 15 7 8 17 37 49

As shown in Table 5 and Figure 1, after 1 hour after the application of the skin forest bath lotion according to the present invention it was confirmed that the moisturizing power is about 60% higher than the water content of the original skin before application, even after about 2 hours It maintains an increased moisturizing rate by% and also shows excellent moisturizing power compared to other baby lotions on the market.

2) long-term moisturizing effect measurement

Clinical trials for improving skin symptoms of skin dryness and mild atopic dermatitis patients using the skin forest bath compositions (lotion, cream and bath) of the present invention obtained in Examples 1 to 3 in Seoul National University were performed as follows.

Twenty girls / boys suffering from mild atopic dermatitis or dry skin aged between 0 and 12 years old were asked to use the three product groups for 4 weeks under normal conditions and to measure their moisturizing power after the first, 2 and 4 weeks. It was. When measuring the moisturizing power was measured in the general state of the skin, not a lotion / cream or the like. Unlike short-term moisturizing tests, lotions, creams, and baths are used for normal use, and the use of them is to measure the change in the skin's own moisturizing ability. In general, the regeneration cycle of the skin is 28 days to 1 month, so the product is used for 4 weeks, and the test shows how much the skin's own moisturizing ability is improved. Specifically, by using a moisture meter CM825 (Courage + Khazaka, Germany), the moisture content is measured by measuring the moisture content of the skin before and after using the product three times before, after 2 weeks, and after 4 weeks of use. The measurements were compared. The measurement sites were bilateral antecubital fossa and popliteal fossa. Three measurements were taken per site, and the averages were calculated. The results were compared with Tables 6 to 9, and FIGS. 2 and 3. Indicated. The moisture meter (CORNEOMETER CM825) is a device that can measure the transdermal moisture content through the measurement of the capacitance of the small current delivered through the probe (contact) in contact with the skin surface. Moisture content and electrostatic load capacity tend to be proportional, so the higher the moisture level of the skin, the higher the value. The unit is an arbitrary unit, and the number is 0-130. Generally, it is judged as "very dry" if the value is less than 30 for electric poles, "dry" for more than 30 and less than 45, and "sufficiently moistureized" for more than 45.
