Irritant potential of different washing procedures used for heavy-duty soiling: Short and intense or longer and mild?

Background: To prevent irritant contact eczema even in occupational fields with heavy-duty soiling, it is generally recommended to use 'mild' hand cleansers (mild detergent without grits, MC). On the other hand, since grit-containing cleansers (GC) show a higher washing power that minimizes washing time, their usage is generally preferred in specific occupational fields.

Objectives: To compare whether a shorter, intense washing period might cause less skin damage than a longer washing period with an MC.
