Definitions

  • the present invention relates to detergents or cleaners, preferably liquid detergents containing at least one protease, at least one compound of formula (I) and / or of formula (II), which acts as a protease inhibitor and thus is a suitable enzyme stabilizer, and a salt of Formula (III), which enhances the action of the protease inhibitor. Also part of the invention are the corresponding washing and cleaning methods, the use of the agents described herein and the use of a salt to increase the effect of a peptide stabilizer in a protease-containing detergent or cleaning agent.
  • enzymes in detergents and cleaners have been established in the art for decades. They serve to extend the range of services of the funds concerned according to their specific activities. These include in particular hydrolytic enzymes such as proteases, amylases, lipases and cellulases. The first three hydrolyze proteins, starches and fats and thus contribute directly to soil removal. Cellulases are used in particular because of their tissue effect.
  • Another group of washing and cleaning agent enzymes are oxidative enzymes, in particular oxidases, which, if appropriate, in combination with other components, are preferably used to bleach soiling or to produce the bleaching agents in situ.
  • enzymes which are subjected to constant optimization, further enzymes are constantly being made available for use in detergents and cleaners in order to be able to optimally address particular soiling, such as pectinases, ⁇ -glucanases, mannanases or other hemicellulases (glycosidases) Hydrolysis in particular of special vegetable polymers.
  • soiling such as pectinases, ⁇ -glucanases, mannanases or other hemicellulases (glycosidases) Hydrolysis in particular of special vegetable polymers.
  • the other many pathway is to add chemical compounds that inhibit the proteases and thus act collectively as stabilizers for proteases and the other proteins and enzymes contained. It must be reversible protease inhibitors, since the protease activity is only temporarily, especially during storage, but not be suppressed during the cleaning process.
  • Polyols in particular glycerol and 1,2-propylene glycol, benzamidine hydrochloride, borax, boric acids, boronic acids or their salts or esters are established as reversible protease inhibitors in the prior art.
  • These include, in particular, derivatives having aromatic groups, for example ortho, meta or para-substituted phenylboronic acids, in particular 4-formylphenylboronic acid, or the salts or esters of the abovementioned compounds.
  • a particularly good protection results when boric acid derivatives are used together with polyols, since these can then form a complex stabilizing the enzyme.
  • peptide aldehydes that is, oligopeptides with reduced C-terminus, especially those of 2 to 50 monomers are described for this purpose.
  • peptidic reversible protease inhibitors include ovomucoid and leupeptin.
  • specific, reversible peptide inhibitors and fusion proteins from proteases and specific peptide inhibitors are used for this purpose.
  • enzyme stabilizers are amino alcohols such as mono-, di-, triethanol- and -propanolamine and mixtures thereof, aliphatic carboxylic acids up to C12, such as succinic acid, other dicarboxylic acids or salts of said acids. End-capped fatty acid amide alkoxylates are also established for this purpose. Certain organic acids used as builders are capable, as disclosed in WO 97/18287, of stabilizing an enzyme in addition to their builder function.

  • Subtilases are naturally formed by microorganisms; Of these, in particular, the subtilisins formed and secreted by Bacillus species are to be mentioned as the most important group within the subtilases.
  • polyols such as glycerol and 1, 2-propylene glycol have proved to be unfavorable due to their high levels of use necessary concentrations, because the other active ingredients of the respective agents can thus be contained only in correspondingly lower proportions.
  • boric acid derivatives occupy an outstanding position among the serine protease inhibitors (stabilizers), which are effective at a comparatively low concentration.
  • the boric acid derivatives have a significant disadvantage: many of them, such as borate, form undesirable by-products with some other detergent ingredients, so that they are no longer available in the agents concerned for the desired cleaning purpose, or even remain as an impurity on the laundry.
  • Peptide-based protease stabilizers do not have the disadvantages mentioned for boric acid derivatives. However, peptide-based protease stabilizers, when used in moderate concentrations, exhibit significantly reduced protease stabilizer performance compared to the boric acid standard stabilizer (1 wt% boric acid based on the total weight of the agent).
