A detergent composition is disclosed which comprises a surfactant selected from anionic, nonionic, cationic, amphoteric and zwitteronic detergent-active compounds and mixtures thereof; a detergency builder comprising zeolite P having a silicon to aluminium ratio not greater than 1.33 (zeolite MAP); and a proteolytic enzyme having an isoelectric point below 10. Alcalase is exemplified. Preferably the composition is free of enzymes having an isoelectric point above 10.
Une composition détergente comprend un tensioactif sélectionné parmi des composés anioniques, non ioniques, cationiques, amphotères et zwitterioniques, agissant comme détergents, et des mélanges de ceux-ci; un adjuvant au pouvoir détergent comprend la zéolite P ayant un rapport silicium/aluminium inférieur à 1,33 (zéolite MAP); et une enzyme protéolytique ayant un point isoélectrique inférieur à 10. L'alcalase est un exemple. La composition est de préférence exempte d'enzymes ayant un point isoélectrique supérieur à 10.
