Abstract: 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.

Abstract: A method and an apparatus are described to prepare monolayers of particles (or molecules ) (3), realizing the steps of: injecting a liquid film (2) with particles (3) dispersed on the external surface of a rotary member (1); adjusting the surface charge density of the particles (3) by injecting adsorption reagents (10), carrying particles (3) placed on film (2) surface so that they form a substantially uniform monolayer (5); putting the monolayer (5) on the liquid film surface (2) in contact with a substrate (7); and advancing the rotary member (1) longitudinally with respect to the substrate (7), in both directions, so that the monolayer (5) is detached from the liquid film (2) and attached to the substrate (7).
