Abstract

L'invention concerne un composition de détergent liquide comprenant une dispersion de gouttelettes lamellaires dans une phase aqueuse continue, qui comprend une enzyme et présente au moins deux des trois caractéristiques de stabilisation suivantes (1)-(3): (1) le rapport en poids de la totalité de sels solubles dans l'eau à la quantité d'eau dans la composition totale est d'au moins 0,25:1; (2) la solubilité de l'enzyme dans une solution de citrate de sodium-Oaq à 25 % dans de l'eau désionisée est au plus de 50 % en poids; et (3) la composition comprend en outre au moins un stabilisateur d'enzyme ne contenant pas de bore, représentant de 0,1 % au moins en poids; dans cette composition, l'enzyme possède une activité résiduelle d'au moins 10 %, après stockage de la composition à 37 DEG C pendant 4 semaines à partir de sa date de fabrication, et la composition ne contient pas plus de 0,01 % en poids de bore. Si une composition ne présente que les caractéristiques (1) et (2), et que le stabilisateur d'enzyme ne contenant pas de bore comprend un sel de calcium soluble dans l'eau, la quantité totale de sel de calcium soluble dans l'eau est alors d'au moins 0,3 % en poids de la composition totale. Si une composition présent toutes les caractéristiques (1), (2) et (3), le stabilisateur d'enzyme ne contenant pas de bore comprend alors au moins une matière autre qu'un composé de lignine
