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.
Claims20
A stabilized liquid enzyme composition comprising:
- an enzyme stabilizing agent, wherein said agent is an amphoteric surfactant;
- and
- a combination of more than one enzyme, wherein the composition does not have loss in performance for at least about 40 days.
A stabilized liquid enzyme composition comprising:
- an imidazoline-derived amphoteric surfactant enzyme stabilizing agent;
- a combination of more than one enzyme;
- and
- a solvent;
- wherein the composition has compositional stability for at least 40 days, and wherein the ratio of the enzyme stabilizing agent to the enzymes is from about 64:1 to about 1.1.
2 more elements
A method of cleaning comprising:
- applying a liquid stable enzyme composition to an article to be cleaned, wherein the liquid stable enzyme composition comprises an imidazoline-derived amphoteric surfactant enzyme stabilizing agent, a combination of enzymes including a protease enzyme, and a solvent, wherein the composition has compositional stability for at least 40 days, and wherein the ratio the enzyme stabilizing agent to the enzymes is from about 64:1 to about 1:1.
