- the test subject's arms were placed in an atmosphere of 50% humidity for 30 minutes at 25. At this point, the keratin water content of both arms was measured by the electrical conductivity of the skin surface (high-frequency resistance meter, SKICON—20) 0, manufactured by Hamamatsu). Next, the right arm was covered with a film obtained in the same manner as in Example 1 except that 10 parts by weight of olive oil was used as a drug, for 15 minutes, and then the film was removed. The amount was measured. In addition, as a control, the left arm
- the sheet of the present invention exhibits the following effects when wrapping is used, in addition to the above effects. That is, since the skin surface is sealed by wrapping, the penetration of the drug is fast, and sufficient transdermal absorption is performed by the steaming effect. Furthermore, rappi Protection from external stimuli, for example, when itchy skin, can prevent roughening due to scratching.
- the sheet of the present invention has a simple structure, it has excellent workability and can be manufactured efficiently.
