- the enzymes are in the form of a so-called aqueous enzyme particle suspension (Enzyme slurry).
- aqueous Enzyme particle suspension is obtained by taking the above Enzyme concentrates in a manner known per se, e.g. B. by precipitation processes, spray drying or crystallization the enzymes precipitated and the precipitate thus obtained on known way back in liquid, e.g. B. the mother liquor or a suitable buffer solution, saline solution or amino acid solution, suspended.
- Suitable precipitation processes according to which the enzymes precipitate out of the enzyme concentrates let are z. B. the known methods by which the enzymes by adding salts, e.g. B.
- Enzyme preparations as an enzyme particle suspension are an enzyme crystal suspension (Enzyme crystal slurry).
- an aqueous e.g. B. 5 to 20% solution of an alkali or Add alkaline earth halide salt, if necessary to 20 to Heated to 35 ° C and awaiting crystallization of the enzyme.
- an aqueous 10% alkali chloride solution is used, especially a 10% saline solution.
- the enzyme crystal suspension of a protease in particular an alkaline protease such as, for example, is preferably processed in the liquid enzyme preparations according to the invention.
- the liquid constituents according to the invention contain as main constituent Enzyme preparations 80 to 95.5% by weight, preferably 80 up to 90% by weight of a liquid alkylene oxide polymer based Ethylene diamine with a molecular weight in the range of 500 to 8,200.

- liquid washing and Detergents containing the liquid enzyme preparations according to the invention contain.
- Those according to the invention are preferred liquid enzyme preparations in liquid detergents for Cleaning of textiles or in liquid dish detergents used. Except for the liquid enzyme preparations can the detergent or cleaning agent formulations all ingredients that are customary in the prior art and Auxiliaries for the formulation of liquid washing and cleaning agents e.g. B. surfactants, builders (builders) and optionally bleach or bleach precursors in contain common quantities.
- the auxiliaries include e.g. B. enzyme stabilizers, complexing agents and chelating agents, Foam regulators and additives such as corrosion inhibitors, Antistatic agents, dyes, fragrances, bactericides, fungicides and activators.
- liquid enzyme preparations according to the invention show surprisingly good, for use in liquid laundry and Detergent formulations have particularly suitable properties. So have the liquid enzyme preparations according to the invention a very high storage stability, even over a longer period Period the enzyme activity of these liquid enzyme preparations processed enzymes practically unchanged remains. In addition, the liquid according to the invention Enzyme preparations very stable to sedimentation. Because of their low Viscosity are the liquid enzyme preparations according to the invention easy to dose and therefore very good for processing suitable in liquid detergents or cleaning agents.
- a Bacillus alcalophilus (DSM No. 5466) fermented. From the fermenter broth was through Filtration using filter aids and flocculants insoluble accompanying substances separated. In the filtrate the pH was adjusted to 5.2 and by ultrafiltration by a factor of 4 to a protease activity of approx. 750,000 DU / ml concentrated. After the ultrafiltration was a 10% saline solution is added, heated to approx. 30 ° C and waiting for the enzyme to crystallize. You got one Enzyme crystal suspension, which in a manner known per se Removal of the mother liquor to a protease activity of approx. 3.6 million DU / ml was concentrated.
- the liquid enzyme preparations according to the invention were prepared by placing the specified amount of Synperonic T304 R in a vessel to which the specified amount of Aerosil 200 R was slowly added with vigorous stirring. Then the enzyme crystal suspension previously homogenized by stirring was added with stirring. A sedimentation-stable liquid enzyme preparation of the highly alkaline protease with a protease activity of approx. 678,000 DU / g was obtained.
