The test method comprises the following steps: during the test, after the test site was first washed with clean water, the subject used the corresponding disinfecting composition.

Wherein, according to the patch test result, if severe irritative conditions (itching, stabbing pain, etc.) occur during the use of the test sample (the disinfecting composition of comparative example 5) having a suspected reaction, a large amount of clear water is used for washing in time, and the experiment is ended.

The moisture content of the subjects was measured before and after the test. The skin Moisture content was measured by a skin Moisture meter, and the Measurement result was expressed by a set Moisture Measurement Value (MMV/%).

The test results are shown in table 4.

TABLE 4 skin moisture content test results (MMV/%) before and after use of the disinfecting compositions of examples 1 to 5 and comparative examples 1 to 5

As can be seen from the test results in Table 4, the disinfecting compositions of examples 1 to 5 and comparative examples 1 to 4 can significantly increase the water content of the skin, and exhibit more excellent moisturizing effect. While comparative example 5 was less effective in increasing the moisture content of the skin.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the true spirit and scope of the present invention.
