Abstract

L'invention porte sur un assouplissant parfumé pour le linge, lequel contient un composant d'assouplissement du linge ainsi que des substances odorantes encapsulées de même qu'également des substances odorantes non encapsulées. Par un choix spécial en particulier des substances odorantes encapsulées, cet assouplissant pour le linge permet des avantages olfactifs inattendus sur les textiles traités par lui dans le cadre d'un procédé de lavage usuel, en particulier en ce qui concerne les aspects plaisir, intensité et durabilité de la perception odorante. A ce sujet, la quantité totale de parfum, qui est contenue dans l'assouplissant, peut même être réduite et en conséquence les avantages olfactifs peuvent être obtenus sur les textiles traités.
