Abstract: The present disclosure relates to menstrual fluid simulant compositions that mimic the properties of real menstrual fluid, where the menstrual fluid simulant compositions comprise vesicle dispersions of quaternary ammonium compounds and linear polymers. The present disclosure also relates to related methods and uses.

Abstract: A method of manufacturing a strip of a fibrous structure includes imparting an interlocking motif onto a strip, the interlocking motif includes a first pattern and a second pattern interlocked with the first pattern. The first pattern has a first major design element and a first minor design element and the first major design element is at least partially imparted in a central region and the first minor design element is at least partially imparted in one of the group consisting of a first edge region and a second edge region. The second pattern includes a second major design element and a second minor design element, and the second major design element is at least partially imparted in the central region and the second minor design element is at least partially imparted in one of the group consisting of the first edge region and the second edge region.
