Abstract
The present invention discloses water-responsive, and optionally flushable compositions with improved stability to aqueous fluids comprising water or water vapor. The compositions of the 10 present invention comprise a water-responsive polymer and organically modified clay particles. In one embodiment, the water-responsive polymer is a polymer of ethylene oxide, specifically poly(ethylene oxide) and specific graft copolymers of poly(ethylene oxide). Films of the present invention are water-responsive and breathable and are especially useful for personal care applications including disposable diapers, feminine pads, pantiliners and training pants. Advantageously, compositions of the present invention have reduced melt viscosity and are more easily melt processed into films, fibers and other articles.
