- Preferred particulate agents contain enzymes in amounts of 0.1 to 10% by weight, preferably 0.5 to 8% by weight and in particular 1 to 5% by weight, in each case based on the total (powdered) agent.
- the particulate agents can be colored with suitable dyes, wherein, as explained above, in a preferred embodiment of the process according to the invention these dyes are contained in the powdered powder which is ground under drying conditions.
- Dyes preferred in the context of the present invention the selection of which does not pose any difficulty for the person skilled in the art, have a high storage stability and insensitivity to the other constituents of the particulate agents and to light, and no pronounced substantivity towards textile fibers in order not to dye them.
- the particulate agents are used as detergents and cleaning agents, preference is given to all colorants which can be oxidatively destroyed in the washing process, and also mixtures thereof with suitable blue dyes, so-called blue toners. It has proven to be advantageous to use colorants which are soluble in water or at room temperature in liquid organic substances.
- anionic colorants for example anionic nitroso dyes, are suitable.
- One possible dye is, for example, naphthol green (Color Index (CI) Part 1: Acid Green 1; Part 2: 10020)., That is as a commercial product, for example as Basacid ® Green 970 from BASF, Ludwigshafen available, as well as mixtures thereof with suitable blue dyes.
- Pigmosol ® Blue 6900 (Cl 74160), Pigmosol ® Green 8730 (Cl 74260), Basonyl ® Red 545 FL (Cl 45170), Sandolan ® Rhodamine EB400 (Cl 45100), Basacid ® Yellow 094 (Cl 47005), Sicovit ® Patentblau 85 E 131 (Cl 42051), Acid Blue 183 (CAS 12217-22-0, Cl Acidblue 183), Pigment Blue 15 (Cl 74160), Supranol ® Blau GLW (CAS 12219-32-8, Cl Acidblue 221 )), Nylosan ® Yellow N-7GL SGR (CAS 61814-57-1, Cl Acidyellow 218) and / or Sandolan ® Blue (Cl Acid Blue 182, CAS 12219-26-0).
- colorants When choosing the colorant, care must be taken to ensure that the colorants do not have too strong an affinity for textile surfaces and especially for synthetic fibers. At the same time, when choosing suitable colorants, it must also be taken into account that colorants have different stabilities against oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant in the washing or cleaning agents varies. For highly soluble dyes, for example, the above-mentioned Basacid ® Green or the above-mentioned Sandolan Blue ®, are typically selected dye concentrations in the range of some 10 "2 to 10" 3 wt .-%.
- the suitable concentration of the colorant in washing or cleaning agents is typically a few 10 "3 to 10 " *% by weight.
- Fragrances in the context of the present invention may be contained in the particulate agents in order to improve the aesthetic impression of the products and to provide the consumer with a visually and sensorially “typical and distinctive” product in addition to the performance of the product.
- fragrance compounds e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used.
- Fragrance compounds of the ester type are e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalylbenzoate, benzyl formate, ethylmethylphenylglycineate, allylcyclohexylpropionate, styrallylpropionate and styrallylpropionate.
- the ethers include, for example, benzyl ethyl ether, the aldehydes e.g. the linear alkanals with 8-18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones e.g.
- the hydrocarbons mainly include the terpenes such as limonene and pinene.
- perfume oils can also contain natural fragrance mixtures as are available from plant sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are muscatel, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galba oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.
- the fragrances can be incorporated directly into the particulate agents, but it can also be advantageous to apply the fragrances to carriers.
- carrier materials for example, cyclodextrins have proven themselves, it being possible for the cyclodextrin-perfume complexes to be additionally coated with further auxiliaries. It is also possible to package the fragrances with an LCST substance.
- Foam inhibitors which can be contained in the particulate agents according to the invention or in the particulate agents within the scope of the method according to the invention and which are used in particular in textile cleaning are, for example, soaps, paraffins or silicone oils, which can optionally be applied to carrier materials.
- suitable Anti-redeposition agents which are also referred to as soil repellents, are, for example, nonionic cellulose ethers such as methyl cellulose and methylhydroxypropyl cellulose with a proportion of methoxy groups of 15 to 30% by weight and of hydroxypropyl groups of 1 to 15% by weight, in each case based on the nonionic cellulose ether and the polymers of phthalic acid and / or terephthalic acid or of their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof. Of these, the sulfonated derivatives of phthalic acid and terephthalic acid polymers are particularly preferred.
- Optical brighteners can be added to the particulate agents, provided they are used as detergents and cleaning agents to remove graying and yellowing of the treated textiles. These substances absorb the fibers and bring about a brightening and simulated bleaching effect, by converting invisible ultraviolet radiation into visible longer-wave light, the ultraviolet light absorbed from the sunlight being emitted as a slightly bluish fluorescence and resulting in pure white with the yellow tone of the grayed or yellowed laundry.
- Suitable compounds come, for example, from the substance classes of 4,4 ' -Diamino-2,2'-stilbenedisulfonic acids (flavonic acids), 4,4'-distyryl-biphenyls, methylumbelliferones, coumarins, dihydroquinolinones, 1, 3-diarylpyrazolines, naphthalic acid imides, benzoxazole, benzisoxazole and benzimidazole systems and by He terocycle-substituted pyrene derivatives.

- Graying inhibitors in textile cleaning agents have the task of keeping the dirt detached from the fibers suspended in the liquor and thus preventing the dirt from being re-absorbed.
- Water-soluble colloids of mostly organic nature are suitable for this purpose, for example the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch.
- Water-soluble polyamides containing acidic groups are also suitable for this purpose. Soluble starch preparations and starch products other than those mentioned above can also be used, for example degraded starch, aldehyde starches, etc.
- Polyvinylpyrrolidone can also be used.
- Cellulose ethers such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof can also be used as graying inhibitors in the particulate compositions.
- Antimicrobial agents such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof can also be used as graying inhibitors in the particulate compositions.
- Antimicrobial agents such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof can also be used as graying inhibitors in

- particulate agents which have been powdered with the aid of the powder agents described above have, inter alia, improved flowability and ensilability.
- powdering agents have proven to be particularly advantageous in this connection which, in turn, are distinguished by a certain flow behavior.
- a common standard method for the quantitative determination of the shear stress of a pre-consolidated powder as a measure of the flow behavior of such a powder is the determination of the shear stress using a Johanson hang-up indicator.
- the powder to be tested is solidified by the action of a certain pressure (hardening stress) and the solidified cylindrical bulk sample is then exposed to a vertical compressive stress that acts on the sample at a defined angle (shear angle). At a certain voltage, the sample breaks, i.e. flows.
- This compressive stress is also known as compressive strength or bulk solids strength. There is therefore a flow limit specific to the bulk material which must be reached in order to make the bulk material flow. The lower the voltage under which the bulk material flows, the better its fluidity can be assessed.
- the present invention furthermore relates to the use of powdering agents ground under drying conditions for the powdering of particulate agents.
- the dye (s) in amounts of 0.1 to 70 wt .-%, preferably from 0.2 to 50 wt .-% and in particular from 0.5 to 30 wt .-%, each based on the total weight of the powder is included, is particularly preferred.
