CA 2450149

A water soluble package comprises a substantially non-aqueous liquid rinse conditioning composition therein, wherein the water soluble package comprises a polymeric film. A process for conditioning fabrics comprises the step of adding to the rinse cycle of a washing operation the water soluble package and rinse conditioning composition therein, allowing or causing the package to break so as to release the contents therefrom and contacting the composition with fabric being laundered. The package is either disposed in the drum at the beginning of the wash cycle, remains intact through the wash cycle and disperses and/or dissolves at the beginning of or during the rinse cycle or is disposed in the rinse compartment of the dispenser drawer or in the drum between the wash and rinse cycles and disperses and/or dissolves immediately.

La présente invention concerne un contenant hydrosoluble en film polymère renfermant un adoucissant liquide non aqueux. L'invention concerne également un procédé de rinçage de linge avec un adoucissant. A cet effet, on ajoute au cycle de rinçage d'une charge de lessive l'emballage hydrosoluble avec l'adoucissant qu'il renferme. On fait ensuite en sorte que le contenant, de façon provoquée ou spontanée, se désintègre et libère son contenu, l'adoucissant entrant en contact avec le linge. Le contenant se met au début du cycle de lavage directement dans le tambour où il reste intact pendant tout le cycle de lavage puis se désintègre et/ou se dissout en début ou en cours de cycle de rinçage. On peut également mettre le contenant dans le compartiment adoucisseur du tiroir du distributeur à produits de la machine ou dans le tambour entre les cycles de lavage et de rinçage, auquel cas il se désintègre et/ou se dissout immédiatement.
