An aqueous softening and antistatic agent composition comprising a quaternary ammounium compound and a biodegradable nonionic surfactant, which composition comprises a quaternary ammounium compound having the formula <see Fig. 1> wherein R1 is a C6 - C22 hydrocarbyl group; and X is halogen or SO4 2-, in a concentration of at least about 15% by weight. The surfactant is a linear alkoxylated fatty acid or a linear alkoxylated unsaturated alcohol. Furthermore a method for providing cellulosic materials with a reduced tendency to retain an electrostatic charge as well as providing said material with improved softness, wherein the cellulosic material is treated with said composition, and fluff obtainable from fluff pulp treated with the composition.
Divulgation de la composition d'un agent assouplissant et antistatique aqueux, comprenant un composé d'ammonium quaternaire et un surfactant non ionique biodégradable. La composition comprend un composé d'ammonium quaternaire ayant la formule <voir fig. 1>, dans laquelle R1 est un groupement hydrocarbyle en C6-C22, et X est un atome d'halogène ou un groupement SO4 2-, dans une concentration d'au moins environ 15 % en poids. Le surfactant est un acide gras alcoxylé linéaire ou un alcool insaturé alcoxylé linéaire. L'invention dévoile aussi une méthode pour fournir des matières cellulosiques ayant moins tendance à retenir une charge électrostatique, ainsi que pour améliorer l'assouplissement de la matière en question, consistant à traiter la matière cellulosique avec la composition susmentionnée, et de la poussière que l'on peut obtenir à partir de la pâte à poussière traitée avec la composition
