	Example 1	Example 2	Example 3	Comparative example 1	Comparative example 2
						Test results	Positive for	Positive for	Positive for	Positive for	Negative of

As can be seen by combining examples 1 to 3 and comparative examples 1 to 2 with tables 3 and 6, the self-heating moisturizing bath oil according to examples 1 to 3 and the bath product according to comparative example 1 show positive results, and the moisture content of the stratum corneum in the test area is significantly different before and after the use of the product, indicating that the test sample has a moisturizing effect. The bath product of comparative example 2 was negative in test results, and no significant difference in the moisture content of the stratum corneum in the test area was observed before and after the use of the product, indicating that the test sample had poor moisturizing effect.

3. Moisturizing efficacy evaluation test instrument: a skin moisture content tester and a skin moisture loss tester. Skin moisture content tester model Corneometer825 Courage + Khakaza Cologne Germany. Skin moisture loss tester model TM300Courage + Khakaza Cologne Germany.

Test objects: the self-heating moisturizing bath oil in the example 1 and the bath products in the comparative examples 1-2.

The MMV test method comprises the following steps:

the testing principle is as follows: the capacitance method is used for measuring the moisture content of the stratum corneum of the human skin, the principle is that the difference of dielectric constants of water and other substances is obvious, the measured capacitance values of the skin are different according to the difference of the moisture content of the skin, and the observation parameters can represent the moisture value of the skin.

Experimental conditions and volunteer requirements:

and (3) testing environmental conditions: the test environment temperature is 22 ℃ plus or minus 1 ℃ and the humidity is 50 percent plus or minus 5 percent, and real-time dynamic monitoring is carried out.

The volunteer requires:

at least 30 effective volunteers; the age is between 16 and 65 years old; the basic value of the capacitance method skin moisture tester of the forearm test area is between 15 and 45 years old; those without severe systemic disease, immunodeficiency or autoimmune disease; those with inactive allergic disease; those who have not had a history of severe allergy to skin care cosmetics in the past; hormone drugs and immunosuppressants have not been used in the last 1 month; no other clinical trial participants; the tested object is used according to the specification and the data is complete; all volunteers should fill out informed consent before testing.

Preparation before testing:

any product (cosmetics or external medicine) cannot be used for 2 to 3 days before the tested part. Before testing, subjects were asked to clean the forearm of both hands and wipe clean with dry paper. After cleaning, measurement zone markers were made inside the forearm of the subject's hand. Before formal test, the patient should sit still in a room meeting the standard for at least 30min, and cannot drink water, and the forearms are exposed and placed in a test state to keep relaxed.

The testing steps are as follows:

in the experiment, the inner side of the left arm and the right arm is marked with a 3 cm-3 cm test area, the same arm can be simultaneously marked with a plurality of areas, and the intervals of the areas are 1cm. Both the test product and the placebo were randomly distributed on the left and right arms. The measurement of the test area and the control area was performed using a capacitance skin meter, and each area was measured 5 times in parallel. The blank value of each test area was measured and then the test product was evenly spread into the test area using a latex finger cuff at a dose of 2.0mg + -0.1 mg sample/cm 2. After application, the skin moisture content was measured at 1h, 2h and 4h for the test area and the blank area, respectively. The test of the same volunteer was performed by the same measurement staff.

The TEWL test method test principle: fick's law of diffusion. The moisture content emitted by epidermis can be directly measured by measuring the near epidermis (within about 1 cm) through 2 groups of temperature and humidity sensors and the water vapor pressure gradient formed by the loss of the water in the cuticle at different two points. The TEWL value is an important indicator of the barrier of the skin, and a lower TEWL value indicates a better barrier function of the skin, whereas a worse value.

The experimental conditions, requirements of volunteers, preparation before test and test steps are the same as the MMV test method.

The test data respectively measure the TEWL value of each time interval according to the design of the experiment.
