    摘要： The present invention relates to a multi-ply fibrous product comprising at least two fibrous plies, preferably a multi-ply nonwoven product, a tissue paper product or a hybrid thereof comprising at least two tissue paper plies and/or nonwoven plies comprising cellulosic fibers, wherein at least two fibrous plies are bonded to each other by means of an aqueous adhesive composition comprising an adhesive component and a dermatologicaily acceptable acid, and optionally a salt thereof; as well as a process for the manufacture of a this multi-ply fibrous product comprising the steps of a) providing at least two fibrous webs, e.g of tissue paper, b) optionally embossing at least one web in order to provide at least one pattern of protuberances, c) applying an aqueous adhesive composition comprising an adhesive component and a preferably water-soluble, dermatologicaily acceptable acid, and optionally the corresponding salt thereof, to at least one side of at least one fibrous web, e.g, paper tissue web, wherein, if at least one web is embossed, the aqueous adhesive composition is preferably applied to the distal ends of at least a part of the protuberances, d) superimposing at least two webs such that the aqueous adhesive composition is located between at least two superimposed webs, e) bonding at least two webs together, and f) optionally further steps for converting the bonded webs to the final multi-ply product. Due to the acid/buffer content in the adhesive composition, the multi-ply fibrous product of the invention can stabilize natural skin pH.
