Beschreibung
Zusammenfassung:	A multi-ply fibrous product includes at least two fibrous plies, such as a multi-ply nonwoven product, a tissue paper product or a hybrid thereof including at least two tissue paper plies and/or nonwoven plies including cellulosic fibers. At least two fibrous plies are bonded to each other by an aqueous adhesive composition including an adhesive component and a dermatologically acceptable acid, and optionally a salt thereof. A process for the manufacture of this multi-ply fibrous product includes (a) providing at least two fibrous webs, (c) applying an aqueous adhesive composition including an adhesive component and a water-soluble, dermatologically acceptable acid, and optionally the corresponding salt thereof, to at least one side of at least one fibrous web, d) superimposing at least two webs such that the aqueous adhesive composition is located between at least two superimposed webs, and e) bonding at least two webs together.
