Abstract

The disclosure relates to an enzyme stabilization system, compositions with the enzyme stabilization system, and methods of using the enzyme composition. Preferred ratios of acid to amine are effective at stabilizing enzyme. Optional nonionic surfactants and solvents also positively contribute to enzyme stability. The compositions are useful in cleaning applications.
