The present invention relates to detergent compositions comprising a specific lipolytic enzyme and a surfactant system wherein the anionic to nonionic surfactants weight ratio is from 1:1 to 5:1, preferably from 1:1 to 3:1. Such compositions provide improved overall detergency performance: reduced redeposition of greasy/oily substances on fabrics, dishware and hard surfaces thereby enhancing whiteness maintenance, cleaning, spotting, filming and stain removal performances.
L'invention porte sur des compositions détergentes comprenant une enzyme lipolytique spécifique et un système tensio-actif dans lequel le rapport pondéral des tensio-actifs anioniques aux tensio-actifs non ioniques est compris entre 1:1 et 5:1, et de préférence entre entre 1:1 et 3:1. Ces compositions assurent une amélioration générale du pouvoir détergent et limitent le redépôt des substances huileuse/grasses sur les tissus, la vaisselle et les surfaces dures, d'où une meilleure conservation de la blancheur, un meilleur nettoyage, une réduction de la formation des taches et/ou des pellicules, et un accroissement du pouvoir d'élimination des salissures.
