CA 2252361
There is provided a detergent composition containing an amylase enzyme and a builder system comprising an aluminosilicate zeolite, a crystalline layered silicate and most preferably an organic polymeric compound wherein the weight ratio of said crytalline layered silicate to said amylase enzyme (120 KNU/gram activity basis) is from 7:1 to 20:1. In one preferred aspect the detergent composition contains a bleaching system capable of providing delayed release of an organic peroxyacid to a wash solution.
L'invention concerne une composition détergente contenant une amylase et un système d'adjuvant comprenant une zéolite d'aluminosilicate, un silicate à couche cristalline et idéalement un composé polymère organique. Le rapport pondéral du silicate à couche cristalline et de l'amylase (base d'activité 120 KNU/grammes) est compris entre 7:1 et 20:1. Selon une réalisation préférée, la composition détergente contient un système de blanchiment permettant d'obtenir la libération retardée d'un acide peroxy organique dans une solution de lavage.
