The disclosure describes a latently dispersible barrier composite material including an exposed low strength barrier component, an internal water sensitive layer, and a water permeable, inextensible, water dispersible support layer. When exposed to aqueous conditions on the barrier side, the composite prevents it from passing through to the other layers. When exposed to aqueous conditions on the opposite side, the composite readily disperses and may be disposed of by flushing in a toilet, for example. Uses are many and include numerous containment applications such as commode liners, containers for bodily and animal wastes, components of personal care products and the like. Examples of barrier layers include polylactic acid. Examples of water sensitive layers include polyvinyl alcohol. Examples of support layers include low stretch grades of toilet tissue.
