Abstract: Disclosed herein is a homogenous, storage-stable liquid enzyme preparation, including
component (a): at least one enzyme selected from the group of hydrolases (EC 3);
component (b): an enzyme-stabilizing system including
(bi) at least one compound according to general formula (A)
where the variables in formula (A) are as follows:
R1 is selected from H and C1-C10 alkylcarbonyl,
R2, R3, R4 are independently from each other selected from H, linear C1-C5 alkyl, branched C3-C10 alkyl, C6-C10-aryl, non-substituted or substituted with one or more carboxylate or hydroxyl groups, and C6-C10-aryl-alkyl, where alkyl of the latter is selected from linear C1-C8 alkyl or branched C3-C8 alkyl, where at least one of R2, R3, and R4 is not H;
and
(bii) at least one compound selected from boron containing compound and peptide stabilizer,
and
component (c): at least one diol.-

Abstract: A liquid composition, including
component (a): at least one peptide aldehyde, and
component (b): at least two organic solvents, where one organic solvent is 1,2-propane diol and at least one further organic solvent is selected from the group consisting of diols other than 1,2-propane diol in a weight ratio of 1,2-propane diol: at least one diol other than 1,2-propane diol of 25:1 to 1:4.
