The present invention comprises a cleaning composition, particularly an automatic dishwashing composition, comprising an effective amount of a protease enzyme cleaning system comprising the combination of at least one chymotrypsin-like protease enzyme and at least one trypsin-like protease enzyme, where the at least one chymotrypsin-like protease has an enzyme activity ratio of sAAPF-pNA activity/bVGR-pNA activity of at least about 15 and the trypsin-like protease enzyme having an enzyme activity ratio of sAAPF- pNA activity/bVGR-pNA activity of less than about 10.0; and cleaning adjunct materials.
Cette invention se rapporte à une composition détergente, en particulier une composition détergente pour lave-vaisselle, qui comprend une quantité efficace d'un système détergent à base d'enzymes protéases, renfermant une combinaison d'au moins une enzyme protéase du type chymotrypsine et au moins une enzyme protéase du type trypsine. La protéase du type chymotrypsine présente un rapport d'activités enzymatiques activité sAAPF-pNA/activité bVGR-pNA au moins égal à 15 environ et l'enzyme protéase du type trypsine présente un rapport d'activités enzymatiques activité sAAPF-pNA/activité bVGR-pNA inférieur à 10,0 environ; cette invention concerne également les substances d'additifs de détergents.
