Abstract

La présente invention concerne un produit de lavage comportant au moins deux feuilles, qui comprennent un polymère hydrosoluble et ayant différentes vitesses de dissolution dans l'eau, chaque feuille contenant: i) des constituants détergents de lavage, ii) des constituants adoucissants de lavage, iii) un agent aromatique, ou iv) au moins deux parmi ceux-ci. Étant donné qu'au moins deux feuilles possèdent des vitesses de dissolution différentes, selon la présente invention, le temps de décharge des constituants de lavage contenus dans les feuilles peut être contrôlé, permettant ainsi d'avoir un excellent effet de lavage.
