Abstract
Five kinds of skin barriers on the market were tested comparatively on the subject of physical skin irritation that occurred whlie they were applied to the skin and also when they were peeled off.
Patch tests were made on 12 healthy men. The patches were applied 3 times consecutively,for 48 hours at a time. New patches were applied each time to the same location. Peeling power was checked each time and changes of skin condition were observed. The results were as follows：
1. There were clear differences in peeling power on each testees even when the same type of skin barriers were applied. We understand from this that the peeling power depends on volume of sweat,and weight-to-height ratio of the testees.
2. Peeling power increased as application was repeated.
3. The edges of 2 kinds of CMC skin barriers became rigid and some erythema were observed around them in 10 testees.
4. One of the CMC skin barriers showed the highest peeling power in all testees.
