Patent

CA 2377942

The present invention relates to detergent compositions, including laundry, dishwashing, and/or hard surface cleaner compositions, comprising a raw starch degrading enzyme characterised by a ratio of activity to degrade raw corn starch (Ra) to activity to degrade gelatinised starch (Ga): [Ra/Ga] above 0.2, preferably above 0.35. Such compositions provide excellent removal of starch- containing stains and soils, and when formulated as laundry compositions, excellent whiteness maintenance and dingy cleaning.

L'invention concerne des compositions détergentes, notamment des compositions de lessive, de lavage de la vaisselle, et/ou d'agent nettoyant pour surfaces dures, comprenant un enzyme susceptible de dégrader l'amidon natif, caractérisé par un rapport dégradation d'amidon natif de mais (Ra)/dégradation d'amidon gélatinisé (Ga): [Ra/Ga] supérieur à 0,2, de préférence supérieur à 0,35. Ces compositions présentent une excellente capacité d'enlèvement des souillures et des tâches contenant de l'amidon, et lorsqu'elles sont formulées sous forme de compositions de lessive, un excellent maintien de la blancheur et une bonne élimination de la grisaille.
