Abstract

La présente invention concerne une formulation enzymatique et dispersante destinée à être utilisée dans la lessive domestique, comprenant (i) 5 à 50 % en poids de tensioactif, autre qu'un dispersant de type diarylphénol ou triarylphénol alcoxylé, choisi parmi les tensioactifs anioniques et non ioniques, la fraction pondérale du tensioactif non ionique/tensioactif anionique étant de 0 à 0,3, (ii) 0,5 à 20 % en poids d'un dispersant de type diarylphénol ou triarylphénol alcoxylé et (iii) 0,0005 à 0,2 % en poids d'enzyme protéase. L'invention concerne également un procédé domestique de traitement d'un textile consistant à (i) traiter un textile avec à partir de 1 g/l d'une solution aqueuse de la composition détergente et (ii) permettre à ladite solution aqueuse détergente de rester en contact avec le textile pendant 10 minutes à 2 jours, puis rincer et sécher le textile.
