ABSTRACT:
Washing and cleaning agents containing benzophenone or benzole anilide derivatives containing carboxyl groups, which function as protease inhibitors and are suitable as enzyme stabilizers. Additional subjects are the use of such compounds as reversible inhibitors of a protease and consequently for a washing or cleaning agent formulation, and additional methods and uses relating thereto.
