Abstract
A dispersible absorbent product having a mechanically weakened multi-layered structure, which comprises at least two mechanically weakened layers joined by a water responsive binder. The mechanically weakened regions enhance the dispersibility of the product in a standard toilet. Additionally, the dispersible absorbent products may be pre-moistened with a composition. The pre-moistened products are stable in storage, easily dispersible down a toilet, and deliver cleaning, conditioning, and like benefits. Methods of making such dispersible absorbent products are also disclosed.
