Abstract
A dispersible wet wipe constructed of at two layers is disclosed. The first outer layer of the wipe substrate may have a density of between about 0.5 and 2.0 grams per cubic centimeter. The second outer layer may have a density of between about 0.05 and 0.15 grams per cubic centimeter. A triggerable binder composition binds said web substrate together. The wet wipe also includes a wetting composition including at least 0.3 percent of an insolubilizing agent.
