Peracid based dishwashing detergent composition

摘要

A warewashing composition for a machine dishwasher and a method of using it is described. The composition comprises effective amounts of an organic peroxy acid, and an amylase enzyme which, when incubated at 55 DEG C. in a solution of 2 mM sodium citrate, 1 mM epsilon phthalimidoperoxyhexanoic acid in 36 ppm water at pH 8.0, has a half-life of two minutes or greater based on an activity vs. time plot obtained via monitoring color development at 405 nm of solution samples incubated with p-nitrophenyl- alpha -D-maltoheptaoside as substrate and gluco amylase and alpha -glucosidase as coupled enzymes; and 1% to 75% by weight of a builder. A 1% aqueous solution of the composition must have a pH of less than 10.
