Abstract
Detergent compositions are disclosed which provide superior cleaning and removal of proteinaceous and starchy soils. Applicants have discovered a surfactant package which acts to enhance and improve the performance of enzymes such as proteases and/or amylases. Compositions for pot and pan warewash detergents and soaks are disclosed, as well as their use in manual or dish machine cleaning.
Claims29
An enzyme surfactant component for inclusion in a detergent composition that optimizes the cleaning ability of the enzyme comprising:
- from about 0.01 wt. % to about 20 wt. % of a protease and an amylase enzyme;
- from about 5 wt. % to about 45 wt. % of a sodium olefin sulfonate and a sodium lauryl ether sulfate present in a weight ratio of about 4 parts of said sodium olefin sulfonate to about 1 part of said sodium lauryl ether sulfate;
- from about 0.01 wt. % to about 25 wt. % of a nonionic surfactant and one or more amphoteric surfactants, wherein the nonionic surfactant comprises a branched secondary alcohol ethoxylate surfactant and/or an alcohol alkoxylate containing both ethylene oxide and propylene oxide polymer segments,
- wherein said component is free of alkyl benzene sulfonate.
A warewash/soak detergent composition comprising:
- from about 0.01 wt. % to about 20 wt. % of a protease and an amylase enzyme;
- from about 5 wt. % to about 45 wt. % of anionic surfactant, comprising sodium olefin sulfonate and sodium lauryl ether sulfate present in a ratio of about 4 parts of said sodium olefin sulfonate to about 1 part of said sodium lauryl ether sulfate;
- from about 0.01 wt. % to about 25 wt. % of a nonionic and an amphoteric surfactant, wherein the nonionic surfactant comprises one or more of a branched secondary alcohol ethoxylate surfactant and/or an alcohol alkoxylate containing both ethylene oxide and propylene oxide polymer segments;
- with the remainder comprising one or more of water, an enzyme stabilizer, a viscosity enhancer, a preservative, fragrance and dye, wherein the detergent composition is free of linear alkyl benzene sulfonate.
An enzyme surfactant component for inclusion in a detergent composition that optimizes the cleaning ability of the enzymes comprising:
- from about 0.01 wt. % to about 20 wt. % of a protease and an amylase enzyme;
- from about 5 wt. % to about 45 wt. % of a sodium olefin sulfonate and a sodium lauryl ether sulfate present in a ratio of about 4 parts of said sodium olefin sulfonate to about 1 part of said sodium lauryl ether sulfate;
- from about 0.01 wt. % to about 25 wt. % of one or more of amine oxide, and/or cocoamidopropyl betaine, wherein the nonionic surfactant comprises a branched secondary alcohol ethoxylate surfactant and/or an alcohol alkoxylate containing both ethylene oxide and propylene oxide polymer segments,
- wherein said component is free of alkyl benzene sulfonate.
