Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include dioleyldimethyl ammonium chloride (i.e., di(octadec-z-9-enyl)dimethylammonium chloride) (DODMAC) and dierucyldimethyl ammonium chloride (i.e., di(docos-z-13- enyl)dimethylammonium chloride) (DEDMAC). Depending upon the paper product characteristic requirements, the saturatiuon level of the fatty acyl groups of the vegetable oils can be tailored. Variables that need to be adjusted to maximize the benefits of using unsaturated vegetable oil based acyl groups include the Iodine Value (IV) of the fatty acyl groups; and the cis/trans isomer weight ratios in the fatty acyl groups.

La présente invention concerne une matière cellulosique fibreuse convenant avantageusement à la fabrication de produits de papier absorbants doux tels que les serviettes de papier, les tampons de démaquillage et le papier hygiénique. Ce produit de papier contient un adoucissant chimique qui est un composé ammonium quaternaire à base d'huile(s) végétale(s). Comme composés adoucissants chimiques à l'ammonium quaternaire à base d'huile(s) végétale(s) la préférence ira notamment au chlorure de dioléyldiméthylammonium (c'est-à-dire chlorure de di(octadec-z-9-enly)diméthylammonium) (DODMAC) ou au chlorure de diérucyldiméthylammonium (c'est-à-dire chlorure de di(docos-z-13-enyl)diméthylammonium) (DEDMAC). Le niveau de saturation en groupes acyle gras des huiles végétales peut être adapté en fonction des besoins exprimés concernant les caractéristiques du produit de papier. Les variables nécessitant une intervention pour optimiser les avantages découlant de l'utilisation de groupes acyle à base d'huile(s) végétale(s) insaturée(s) sont notamment la valeur d'iode (IV) des groupes acyle gras et les rapports pondéraux entre cisisomères et transisomères des groupes acyle gras.
