Abstract: A dissolvable sheet having a water-soluble substrate, and one or more cleaning actives disposed uniformly throughout the water-soluble substrate. The water-soluble substrate is formed from a first substrate builder comprising polyvinyl alcohol, a second substrate builder, such as starch, and sodium laurylglucosides hydroxypropylsulfonate, and is sized and shaped to form a sheet, and hold a premeasured amount of the cleaning active. The substrate dissolves when contacted with a sufficient amount of water, thereby releasing the cleaning active into the water, which also dissolves in the water. A method of making the dissolvable sheet is also disclosed.

Abstract: A method and apparatus for making a laundry detergent sheet. Preferably, the laundry detergent sheet is capable of dissolving in a laundry cycle of an automatic washing machine. The method comprises the steps of preparing a first shelf-stable solution, preparing a second non-shelf-stable solution comprising a portion of the first shelf-stable solution, applying the second non-shelf-stable solution onto a surface, and drying the second non-shelf-stable solution on the surface.

Abstract: 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.
