Abstract: This invention provides a multilayer dissolvable solid article, which comprises two or more flexible, dissolvable, porous sheets. Each of such two or more sheets is characterized by a Percent Open Cell Content of from about 80% to 100% and an Overall Average Pore Size of from about 100 ?m to about 2000 ?m and comprises a water-soluble polymer. At least two adjacent sheets in such dissolvable solid article are characterized by an Adhesion Score (AdS) of no less than 1, while the contacting surfaces of said at least two adjacent sheets are essentially free of adhesives. Preferably, the multilayer dissolvable solid article is essentially free of adhesives.

Abstract: A unitary laundry detergent article that is completely or substantially water-soluble, which contains two or more non-fibrous, surfactant-containing sheets with one or more discrete, surfactant-containing particles located between such sheets. The non-fibrous sheets contain a first surfactant that is relatively less hydrophilic, while the discrete particles contain a second surfactant that is relatively more hydrophilic.
