The invention relates to a further embodiment of the im Main patent described, useful as textile detergents surfactant combinations and the detergents or washing auxiliaries r /. with a content of such surfactant combinations. The invent Products according to the invention are characterized by a content of enzymes.

As enzymes, proteases, amylases and lipases are preferably mentioned below, which can be incorporated into the products according to the invention either alone or in combination with one another. If these are ready-made detergents or washing auxiliaries, the protease content can have activities of 50-5000, preferably 100-2500 LVn / g, the A.ig 3ase content activities of 20-5000, preferably 50-2000 3KB / g. g and their lipase content correspond to activities of 2-1,000, preferably 5-500 IU / g detergent or auxiliary washing agent.

If the preparations according to the invention are surfactant combinations that are often used in commercial laundries in combination with conventional builder substances, the enzyme content of these preparations can be so high that one of the surfactant combinations used in each case and the other components of detergents and detergents used at the same time Product made up of detergents has the enzyme content indicated on the right. Since the surfactant combination consists of 5 - 80, preferably 15 - ^ O % of a finished detergent or auxiliary washing agent.

can be calculated for the surfactant combinations Enzy ^ activities in the case of proteases 62.5-100,000 LVE / g, for amylases 25 - 100,000 SKBE / g and for lipases 2.5 - 20,000 IU / g surfactant combination. However, it is easier to use surfactant combinations with activities as high as those in the upper limit ranges available, only produced if very active enzyme prep * rate are available. It is therefore mostly limited to maximum activity values of 50,000 LVU / g, 50,000 SKBE / g • and 10,000 IU / g surfactant combination. The enzyme activities are preferably in the range of 250 - 15,000 LVU / g, 125 15 000 SKBE / g and 12.5-3 500 IU / g surfactant combination.

The above information about the enzyme content and activities of the preparations according to the invention result from the activities of those enzyme preparations which on the day of registration for use in the detergent sector from the economic Standpoint from appearing usable. From chemico-mixing From the standpoint, the enzyme activities of the

Preparations according to the invention are increased as required, so daiJ the activities in proteases and amylases up to 5-ί can be increased up to 10 times the maximum values given above for lipases. So should in the future Enzyme preparation © with higher enzyme contents are offered, which auc

The enzymes to be used can be obtained from animals, microorganisms such as bacteria or fungi, as well as from plants his / her particular from digestive enzymes, yeasts and bacterial strains * They are usually a complex combination Mixture of different enzymatic active ingredients. Depending on their effect, they are used as proteases, carbohydrases, 2sterases, lipases, oxidoreductases, catalases, peroxidases, Ureases, isomerases, lyases, transferases, desmolases or nucleases. Of particular interest are the ones from Bacterial strains or fungi, such as Bacillus subtilis and Streptornyoes griseus, obtained enzymatic active ingredients. Other useful enzymes are pepsin, pacreatin, trypsin, papain and. Diastass. The enzyme preparations obtained from Bacillus subtilis however, have the advantage over the latter enzymes that they have the advantage over alkali and per compounds and anionic detergent active substances are relatively stable and not yet at temperatures between 45 and 70 C. are significantly inactivated. Their relatively high resistance to oxidizing agents is possibly based on the low content of free sulffcydryl groups.

The enzymes are usually brought into cen trade by the manufacturers with the addition of diluents. Sodium sulfate, sodium chloride, alkali ortho-, pyro- odir polyphosphates, especially tripolyphosphate, are suitable as diluents.

If you wash textiles, especially those made of cotton, which have protein, starch and / or fat-containing soiling, with the surfactant combinations according to the invention or with the detergents according to the invention, the enzymes contained therein have a relatively high effect At low temperatures, this dirt is removed more quickly, especially if it has dried out There are stains of blood, pus, gravy, etc. The textile soft .ttiaoher contained in the products according to the invention can then act on the textiles at a relatively early stage in the washing process. A combined effect of the enzymes and the textile changers is thus achieved.

If the intention is not to use the finished detergents, but rather combinations of surfactants with a content of enzymes to bring this to market, this is entirely possible; the formulations of such enzyme-containing surfactant combinations result easily from the above examples by porting the structural substances (CMC to perborate, as well as Dye and fragrance). However, there is the possibility of using lesser amounts of structural constituents, such as dirt carriers (CMC), complexing agents (EDTA) and brighteners can also be incorporated into the surfactant combinations.

Examples

Detergents were produced in a manner customary per se, the composition of which differed from that of Examples 9-17 of the main patent only in that they contained additional enzymes. For this reason, only the amounts of enzyme are given here, and depending on the desired effect, each of the detergents described in the examples of the main patent can be mixed with any enzyme or combination of enzymes given here. Commercially available products were used as enzymes, which the manufacturer had adjusted to the following activities by adding sodium sulfate in amounts of about 7-15%!

A protease with 125,000 LVE / g. An amylase with 75,000 SKBE / g A lipase at 10,000 IU / g

In the examples, besides the amount of enzyme, there is also the enzyme activity given, based on 1 g detergent.

The foam inhibitors were incorporated into the detergent in the same way as is described in the main patent, or they were mixed with the detergent as fine powders. If they are sprayed on, the foam inhibitors are bound to the solid particles of the respective preparation or a solid component of the preparation; they can completely or partially enclose the particles mentioned. _ßAD ORIGINAL - 10 - * _v
