Abstract (en)
The invention relates to the use of 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 in depositing on fabrics while reducing the inter-cationic interferences usually leading to low deposition densities.
