Abstract

BACKGROUND: Soaps are the most widely used body cleanser and sometimes cause irritation of the skin.
OBJECTIVE
Our purpose was to compare the skin irritancy of 6 soaps using noninvasive techniques.
METHODS
The skin responses to patch test with 6 soaps were measured by visual scoring, evaporimeter and corneometer.
RESULTS
The results are summarized as follows. 1. F soap was shown to cause the least irritancy measured by visual scoring and corneometer. But using evaporimeter, there were no differences in irritancy between the 6 soaps. 2. Through correlation analysis, we found that the evaluation of the evaporimeter was closely related to visual measurement.
CONCLUSION
Soap irritancy can be measured by noninvasive techniques, such as the evaporimeter, corneometer, laser doppler flowmetry and visual scoring. Further study of evaluation after short and repeat contacts with soap are needed.
