  • Concentrated, preferably biodegradable, quaternary ammonium fabric softener compositions containing cationic polymers and process for preparation
    Patent number: 6939844
    Abstract: The present invention relates to aqueous stable, preferably concentrated, aqueous liquid textile softening compositions comprising fabric softener active and cationic polymer in the continuous aqueous phase to provide improved softening. The compositions of the present invention preferably contain diester quaternary ammonium compounds wherein the fatty acyl groups have an Iodine Value of from greater than about 5 to less than about 140. The cationic polymers can provide additional benefits such as dye transfer inhibition, chlorine scavenging to protect fabrics, cotton soil release benefits, etc.
    Type: Grant
    Filed: June 22, 2004
    Date of Patent: September 6, 2005
    Assignee: The Procter & Gamble Company
    Inventors: Megan A. Cooper, Toan Trinh, Errol Hoffmann Wahl, Richard Martin Ward
