The present invention relates to an enzyme preparation comprising component (a): at least one hydrophobically modified polyalkyleneimine, component (b): at least one hydrolase, and optionally component (c): at least one compound selected from solvents, enzyme stabilizers, and compounds stabilizing the liquid enzyme preparation as such; wherein the hydrophobically modified polyalkyleneimine comprises a polyalkyleneimine backbone having a weight-average molecular weight greater than or equal to 200 g/mol and less than 1000 g/mol, and hydrophobic moieties which are covalently attached to the backbone of polyalkyleneimine. The invention further relates to a detergent formulation comprising said enzyme preparation. La présente invention concerne une préparation enzymatique comprenant un composant (a) : au moins une polyalkylèneimine modifiée de manière hydrophobe, le composant (b) : au moins une hydrolase, et éventuellement un composant (c) : au moins un composé choisi parmi les solvants, les stabilisants enzymatiques et les composés stabilisant la préparation enzymatique liquide en tant que telle ; la polyalkylèneimine modifiée de manière hydrophobe comprenant un squelette de polyalkylèneimine ayant un poids moléculaire moyen en poids supérieur ou égal à 200 g/mol et inférieur à 1000 g/mol, et des fractions hydrophobes qui sont fixées de manière covalente au squelette de la polyalkylèneimine. L'invention concerne en outre une formulation de détergent comprenant ladite préparation enzymatique.
