Abstract
Abstract Surface-treating compositions containing ammonioamidate surfaceactive compounds able to exist in either cationic or zwitterionic form are disclosed. The compositions which contain a buffering agent to control pH and the cationic or zwitterionic character of the ammonioamidates are effective in the treatment of fabric or hard surfaces. Hair treating compositions and processes are disclosed. Methods of treating fabric and hard surfaces to provide fabric softening and soil-release properties are also disclosed.
