Title
(EN) MULTILAYER DISSOLVABLE SOLID ARTICLE AND METHOD OF MAKING SAME
(FR) ARTICLE SOLIDE SOLUBLE MULTICOUCHE ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract
(EN)
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 μm to about 2000 μm 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.
(FR)
La présente invention concerne un article solide soluble multicouche qui comprend au moins deux feuilles souples, solubles et poreuses. Chacune de ces deux feuilles ou plus est caractérisée par une teneur en cellules ouvertes en pourcentage allant d'environ 80 % à 100 % et une taille moyenne de pore moyenne d'environ 100 µm à environ 2 000 µm et comprend un polymère soluble dans l'eau. Au moins deux feuilles adjacentes dans un tel article solide soluble sont caractérisées par un score d'adhérence (AdS) inférieur ou égal à 1, tandis que les surfaces de contact desdites au moins deux feuilles adjacentes sont essentiellement exemptes d'adhésifs. De préférence, l'article solide soluble multicouche est essentiellement exempt d'adhésifs.
