ABSTRACT:
A method is disclosed for stabilizing liquid enzyme-containing liquid formulations by adding at least one boron compound and at least one alpha-hydroxy-mono-carboxylic acid or the salt of an alpha-hydroxy-mono-carboxylic acid capable of forming an enzyme-stabilizing compound. An enzyme-stabilized formulation is disclosed comprising an alpha-hydroxy-mono-carboxylic acid or the salt of an alpha-hydroxy-mono-carboxylic acid, a boron containing compound capable complexing with an alpha-hydroxy-mono-carboxylic acid, the complex formed by the boron compound and the an alpha-hydroxy-mono-carboxylic acid, and an enzyme. The invention applies to both enzyme concentrate raw materials, and to useful product formulations.
