1. A stabilized liquid enzyme composition comprising:
- from about 1 wt-% to about 50 wt-% of an enzyme stabilizing agent, wherein said agent is disodium camphodiacetate; and
from about 0.01 wt-% to about 25 wt-% a combination of more than one enzymes comprising at least one protease, wherein the composition retains at least about 80% of its initial enzyme activity after 40 days at ambient temperature; and
wherein the composition is substantially free of organic monocarboxylic acids, boric acid, and borate salts.

Abstract
Liquid stable enzyme compositions and methods of employing the same for cleaning, including warewashing and dishwashing, are disclosed. The stable enzyme compositions preferably employ an amphoteric surfactant stabilizing agent, such as disodium camphodiacetate (CADA), to stabilize a mixture of traditionally unstable enzymes, such as proteases and lipases.
