Abstract
An in-vitro method is provided for determining an optimal combination of materials with respect to a particular menstrual flow condition for use in a feminine care absorbent article. The method involves using a simulated menstrual fluid at a controlled subject flow rate that corresponds to an actual menstrual flow condition, and observing the performance of different material combinations in the in-vitro test as an indication of their respective performance in actual use.
