Disclosed herein are two-component enzymatic peracid generation systems
and methods of using such systems wherein the first component comprises a
formulation of at least one enzyme catalyst having perhydrolysis
activity, a carboxylic acid ester substrate, and a cosolvent and wherein
the second component comprises a source of peroxygen in water. The two
components are combined to produce an aqueous peracid formulation useful
as, e.g., a disinfecting or bleaching agent. Specifically, organic
cosolvents are used to control the viscosity of a substrate-containing
component and to enhance the solubility of the substrate in an aqueous
reaction formulation without causing substantial loss of perhydrolytic
activity of the enzyme catalyst.
