Definitions

  • the invention relates to a liquid, essentially anhydrous enzyme preparation which can be used, for example, as a stock solution for the production of liquid detergents or the like.
  • enzyme solutions of hydrolases, especially proteases are not per se stable in storage. This applies in particular to such enzyme Solutions which are to be used for liquid detergents, since in the purification of the enzyme solutions apparently, in addition to impurities, substances which cause stabilization are also removed.
  • German patent application P 39 18 761 proposes a liquid, water-containing enzyme preparation which contains 1.5 to 20% by weight hydrolases, 20 to 40% by weight propylene glycol and 0.5 to 5% by weight boric acid and / or contains their soluble salts.
  • the enzyme concentrate described there is in the form of a solution which also necessarily contains enzyme stabilizers.
  • the invention thus relates to an essentially anhydrous, liquid enzyme preparation containing 5 to 20% by weight of enzymes, 20 to 60% by weight of precipitant and ad 100% by weight of organic water-miscible solvents.
  • the enzyme preparations according to the invention are suitable for the assembly of a large number of enzymes.
  • Liquid preparations of hydrolases can preferably be prepared in this way.
  • the proteases in particular the proteases of the subtilisin type, are preferred among the hydrolases, but other proteases, such as metalloproteases or animal proteases, can also be prepared in this way.
  • proteases such as those in detergents, in particular liquid detergents, are currently preferred be used.
  • related hydrolases such as, for example, ylases, lipases, cellulases or the like, can also be packaged in this way.
  • the enzymes are dissolved in the organic water-miscible solvent and precipitated with a precipitant, so that they are present as a dispersion. It is preferred to carry out the precipitation step with stirring in order to ensure fine particle size.
  • Alcohols are primarily suitable as organic water-dilutable solvents, and among these in particular polyfunctional alcohols.
  • Particularly preferred polyfunctional alcohols are propylene glycol and / or glycerol.
  • other glycols and the di- and trimers of the abovementioned are also suitable.
  • the person skilled in the art can easily determine the solubility by means of a preliminary test. In the vast majority of cases, however, 1,2-propylene glycol has proven to be the most suitable proposal.
  • surfactants have proven themselves primarily as precipitants, since these prevent or delay sedimentation of the enzyme preparations according to the invention which are present in dispersion.
  • nonionic surfactants are preferred.
  • suitable surfactants the person skilled in the art will primarily use products which are liquid at room temperature. Ethoxylates of alcohols with 6 to 20 C atoms or of alkylphenols with 8 to 12 C atoms in the alkyl part have proven successful. It is known that such products can be produced with any degree of ethoxylation.
  • the low-ethoxylated types (1 to 10 mol, in particular 2 to 5 mol, ethylene oxide / mol alcohol or alkylphenol) are preferred for the purposes of the invention.
  • the enzyme preparations according to the invention can also contain further auxiliaries.
  • substances against loss of activity of the enzyme can also be used.
  • boric acid and its salts, insofar as they are soluble or dispersible in the preparations can be added.
  • Lower carboxylic acids, in particular polyfunctional carboxylic acids such as tartaric acid or citric acid, can also be present. The amount of such substances should not exceed 10% by weight of the total preparation and should be at least 1% by weight.
  • the corresponding enzymes in solid form are used, which can be obtained by precipitation or drying of enzyme solutions.
  • the solid enzymes are then first dissolved in the water-miscible organic solvent and the precipitant is added with stirring until a dispersion has formed. If desired, further auxiliaries can then be added. It is possible to heat slightly during the dissolving process and to cool during the precipitation step, but the low temperature stability of the enzymes above about 60 ° C. must be taken into account.
  • the enzyme preparations according to the invention can be used as a stock solution in the production of liquid detergents and the like.
  • a subtilisin protease which is customary in detergents, was precipitated from concentrated solution in a customary manner, filtered off, dispersed in acetone and filtered off again.
  • 1 g of the enzyme powder thus obtained with the specific protease activity of 2,500,000 HPE / g was then dissolved in 5 g of 1,2-propylene glycol with stirring over a period of 2 hours. With further stirring, 6.6 g of an ethoxylated tallow alcohol (3 mol EO / ol tallow alcohol) were then added. Due to the addition of tallow alcohol, the enzyme precipitated out in a very finely divided form without sedimentation. The result was a thin, well pourable dispersion with a specific activity of 193,000 HPE / g.

Abstract

Les solutions fondamentales d'enzymes devraient être améliorées quant à leur durée de conservation. A cette fin est proposée une préparation liquide d'enzymes essentiellement anhydre, contenant 5 à 20 % en poids d'enzymes, 20 à 60 % en poids de précipitant et, complétée, pour obtenir 100 % en poids solvants organiques miscibles avec l'eau.
