Abstract

Le but de l'invention est d'accroître le pouvoir nettoyant de produits de lavage et de nettoyage contenant un tensio-actif, une lipase et des adjuvants et d'améliorer la stabilité au stockage de l'enzyme dans le produit fini, sans avoir à employer d'ingrédients présentant des inconvénients d'ordre écologique ou difficiles à employer. Cet objectif a été atteint essentiellement par une optimisation du système tensio-actif pour obtenir des produits contenant un composant tensio-actif non ionique comprenant au moins 50 % en poids d'un glucoside de formule R1-O(G)n, dans laquelle R1 désigne un reste alkyle ou alcényle ayant 8 à 22 atomes de C, G désigne une unité glucose et n est un nombre de 1 à 10.
