ABSTRACT:
Compositions including one or more enzymes and as the compatible chelating surfactant, salts of N-acyl ethylenediaminetriacetic acid ("ED3A"). Salts of N-acyl ED3A do not readily denature various enzymes, and thus are highly compatible with such enzymes, and enhance their detergent effectiveness to an unexpected degree.
