ABSTRACT:
The present invention is a tissue web comprising cellulosic fibers and a semi-synthetic cationic polymer having a molecular weight less than about 5 million. The semi-synthetic cationic polymer can be heterogeneously distributed in the tissue web. The semi-synthetic cationic polymer has a degree of cationic substitution of at least 0.2.
