A method for foaming a liquid-based composition, such as a softening composition, onto a tissue is provided. The foam composition can be formed in a foam generator by combining the liquid-based composition and a gas, such as air. The foam composition has a blow ratio, i.e, ratio of air volume to liquid volume, greater than about 3.1. Moreover, the foam composition is also generally stable such that it has a half-life greater than about 3 minutes. In one embodiment, a tissue product having elevated regions and non-elevated regions can be formed with a foam composition such that the elevated regions are applied with a greater amount of the foam composition than the non- elevated regions.

L'invention concerne un procédé de moussage d'une composition à base liquide, telle qu'une composition adoucissante, appliqué sur un mouchoir. On peut préparer cette composition moussante dans un générateur de mousse en mélangeant la composition à base liquide avec un gaz tel que l'air. Cette composition moussante présente un rapport de soufflage, en d'autres termes le rapport entre les volumes d'air et de liquide, supérieur à environ 3:1. Par ailleurs, cette composition moussante est généralement stable, ce qui lui confère une vie moyenne supérieure à 3 min. Dans un des modes de réalisation, on peut former de la mousse sur un mouchoir présentant des surfaces surélevées et des surfaces planes avec la composition de moussage de manière à ce que les surfaces surélevées contiennent plus de composition moussante que les surfaces planes.
