The present invention provides a composition comprising a low-molecular weight, amorphous polyalphaolefin layer and a water-sensitive substrate layer. Preferably, the polyalphaolefin comprises either a propylene-ethylene copolymer or an ethylene-butene copolymer. Polyalphaolefin coated water-dispersible films of the present invention may be advantageously employed in the preparation of a wide variety of products designed to be contacted with aqueous fluids. Although the coated water-dispersible film of the present invention is particularly suited for personal care products, the coated water-dispersible film of the present invention may be advantageously employed in the preparation of a wide variety of consumer products other than personal care products. When the entire product is disposed of in water, the water-sensitive layer is wetted and weakens. Since the polyalphaolefin layer is already mechanically weak, hydraulic force from a toilet flow causes the composition to disperse into pieces small enough to flow through the toilet and beyond without clogging the water system.
