Patent

CA 2172496

The invention relates to a composition comprising cationic fabric softeners, preferably quaternary ammonium esters and (C3-C10) alkyl/aryl polyammonium salts. These polyammonium salts are used to replace partially or fully calcium chloride to aid the cationic fabric softeners deposition on fabrics which reduces the inter-cationic interferences usually leading to low deposition densities.

Composition comprenant des assouplissants cationiques pour textiles, de préférence des esters d'ammonium quaternaire et des sels de polyammonium aryle/alkyle (C¿3?-C¿10?). On utilise ces sels de polyammonium pour remplacer partiellement ou totalement le chlorure de calcium et faciliter le dépôt des assouplissants cationiques sur les tissus, ceci ayant également pour effet de réduire les interférences inter-cationiques qui produisent généralement de faibles densités de dépôt.
