This test is used to determine the mildness of products to which human skin would have longer contact with, for example bath/shower products, detergents, cleaning products etc.
Baseline dryness assessments are recorded for each hand, then volunteers are asked to immerse their hands in different solutions of the test product for 30 min each day for 5 consecutive days. Dryness will again be assessed on Day 5 to make a comparison of the mildness of the products. This test is typically conducted in a panel of 30 volunteers.
