Patent

CA 2695068

The described invention is a flexible laundry sheet made of a mixture of at least a thickening agent, detergent, water and polyvinyl alcohol. The thickening agent is comprised of polymers such as starch, modified starch, or cellulose that, when dried, produce a material that remains solid and flexible when dry, yet dissolves completely in water. The constituents, once mixed in the proper proportion, produce a liquid that is poured onto a drying plate, and after drying results in a flexible, dry, laundry sheet which may be added to laundry. Once in contact with water the laundry sheet dissolves and releases its active ingredients, which may include detergents, surfactants, water softeners, chelating agents, dyes, fragrances, clothes softeners and bleaching agents.
