Title (EN) A PERACID BASED DISHWASHING DETERGENT COMPOSITION
(FR) COMPOSITION DETERGENTE DE LAVAGE DE LA VAISSELLE A BASE DE PERACIDE
Abstract:
(EN) 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 °C in a solution of 2mM sodium citrate, 1mM 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 405nm of solution samples incubated with p-nitrophenyl-$g(a)-D-maltoheptaoside as substrate and gluco amylase and $g(a)-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.
(FR) On décrit une composition de lavage d'ustensiles et de vaisselle, destinée à un lave-vaisselle automatique, ainsi qu'un procédé d'utilisation de celle-ci. La composition comprend des quantités efficaces d'un peroxyacide organique et d'une amylase, laquelle, lorsqu'elle est incubée à 55 °C dans une solution de 2mM de citrate de sodium, d'1 mM d'acide epsilon phtalimidopéroxyhexanoïque dans 36 ppm d'eau à un pH de 8,0, possède une demi-vie de deux minutes ou plus, calculée en fonction de la courbe de temps obtenue par contrôle du développement couleur à 405 nm d'échantillons de solution incubés avec du p-nitrophényl-alpha-D-maltoheptaoside en tant que substrat et une gluco amylase et une alpha-glucosidase en tant qu'enzymes couplées, et 1 à 75 % en poids d'un adjuvant. Une solution aqueuse à 1 % de la composition doit posséder un pH inférieur à 10.
