use of quaternary benzimidazolen as textilweichmacher with concomitant schmutzfreisetzender effect

摘要

Surface-active benzimidazole derivatives able to exist in either cationic or zwitterionic form and useful as textile treating agents are disclosed. The compounds are effective as textile softening agents substantive to fabrics as the ordinary pH of fabric rinsing operations and removable from fabrics in a zwitterionic form under succeeding alkaline washing conditions.
