Definitions
- Bleach activators are important components in detergents, stain salts and machine dishwashing detergents. They enable a bleaching effect even at temperatures below 60 ° C by reacting with a source of hydrogen peroxide - usually perborates or percarbonates - with the release of an organic peroxyacid.
- a large number of reactive organic compounds with an O-acyl or N-acyl group are suitable as bleach activators.
- Representative examples such as N, N, N ', N'-tetraacetylethylenediamine (TAED), glucose pentaacetate (GPA), xylose tetraacetate (TAX), sodium 4-benzoyloxybenzenesulfonate (SBOBS), sodium trimethylhexanoyloxybenzene sulfonate (STHOBSylAcu) tetraacetate ), Di-N-acetyldimethylgiyoxin (ADMG) and 1-phenyl-3-acetylhydantoin (PAH) are in the patents GB-A-836 988, GB-A-907 356, EP-A-0 098 129 and EP-A -0 120 591.
- cationic bleach activators that contain a quaternary ammonium group have become more important because they are highly effective bleach activators.
- Such cationic bleach activators are described, for example, in GB-A-1 382 594, US-A-4 751 015, EP-A-0 284 292 and EP-A-0 331 229.
- R ⁇ R 2 and R 3 are alkyl, alkenyl or aryl groups, form a special class of cationic bleach activators.
- Compounds of this type and their use as bleach activators in bleaching agents are described in EP-A-303 520, EP-A-464 880, EP-A-458 396 and US-4 883 917. In all the compounds described there, the nitrogen atom of the ammonium group is substituted by alkyl, alkenyl or aryl groups.
- Another class of ammonium nitriles is described in German patent application 19 605 526.
- Bleach activators are usually used in granular form in detergents in order to ensure sufficient storage stability and to release the bleach-activating effect only in the wash cycle.
- EP-A-0 037 026 describes a process for producing easily soluble activator granules with active ingredients of between 90 and 98% by weight.
- the pulverulent bleach activator is homogeneously mixed with likewise pulverulent cellulose or starch ethers and then sprayed with water or an aqueous solution of the cellulose ether, granulated at the same time and then dried.
- Similar granules can be produced by spray-drying aqueous slurries containing the activator and the cellulose ether.
- Granules consisting of bleach activator, cellulose ethers and additives of an organic C 3 -C 6 carbon or hydroxy carboxylic acid are described in WO 90/01 535 and WO 92/13 798. While in WO 90/01 535 the organic carboxylic acid is incorporated into the granulate core to accelerate its solubility, in WO 92/13 798 the carboxylic acid is applied to the finished granulate in an additional coating step.
- the acidic protective coat is intended to prevent spotting of the bleaching agent and to protect the color of the fabric.
- WO 94/03 395 claims for the same purpose the use of acidic polymer compounds with a water solubility> 5 g / l (at 20 ° C.) and molar masses of 1000 to 250,000.
- Also known (GB-A 1 507 312) are granules of bleach activators in which mixtures of soaps and free fatty acids are used as granulating aids.
- An anhydrous manufacturing process is known from EP-A-0 075 818.
- the bleach activator is pressed together with an organic binder, for example a fatty alcohol ethoxylate, by compacting under pressure to give particles with a diameter of 0.5 to 3 mm.
- the bleach activator to be granulated is a solid and has a high melting point. This is necessary so that it does not react and decompose with the binder or existing water during production.
- such activators are preferred which have a melting point of preferably at least 100 ° C., in particular at least 150 ° C.
- Suitable granules for use in stain salts represent a further problem.
- Modern formulations consist of mixtures of percarbonate and bleach activator granules.
- inert materials such as sodium carbonate, hydrogen carbonate or sulfate are often added.
- Inert binders or coatings would be of great interest for this area of application.
- Inorganic materials as carriers for bleach activators are known per se.
- liquid activators such as diacetylmethylamine, diacetylbutylamine or acetylcaprolactam
- inorganic adsorbents such as diatomaceous earth, magnesium-aluminum, sodium or calcium aluminum silicates, activated silica or aluminum oxide
- particles can also be produced in which a bleach activator which is solid per se is deposited in a finely divided form on an inorganic carrier material.
- the activator and carrier material are first mixed intimately and an organic solvent (ethanol or toluene) is added, the activator going into solution. Subsequent distillation of the solvent causes the activator to be deposited on the carrier in finely divided form.
- the preferred particle size distribution of the particles according to the invention is between 60 and 250 ⁇ m.
- EP-A-0 240 057 discloses bleach activator granules which are prepared by mixing an activator with inorganic or organic salts, film-forming polymers and small amounts of smectites or aluminum silicates and subsequent granulation in the presence of water. After granulation has taken place, an expensive drying stage is necessary in order to obtain storage-stable granules.
- Bleach activator granules which are obtained by mixing and pressing dry bleach activator and smectites (bentonite) in the absence of water, are known from DE-A 44 39 039. Essentially only TAED is used there as a bleach activator. However, the influence of TAED on washing performance is essentially independent of whether the TAED is in granular form or as a powder.
- the invention thus relates to bleach activator granules consisting essentially of an ammonium nitrile and a layered silicate.
- These granules are obtained by mixing the two components, compressing and crushing the agglomerates obtained to the desired particle size.
- ammonium nitriles which have a melting point above 60 ° C. in granular form can be used for the granules.
- the ammonium nitriles described in the above-mentioned literature come into question, in particular the compounds described in DE 19 605 526. Compounds of the formula are very particularly preferred
- R 1 and R 2 C r C 4 alkyl preferably methyl and X is an anion, for example chloride or methosulfate.
- Granules can contain one or more of these ammonium nitriles or additionally also bleach activators of another structure, for example N, N, N ', N'-tetraacetylethylene diamine (TAED), glucose pentaacetate (GPA), xylose tetraacetate (TAX), sodium 4-benzoyloxybenzenesulfonate (SBOBS), Sodium trimethylhexanoyloxybenzenesulfonate (STHOBS), tetraacetylglucoluril (TAGU), tetraacetylcyanoic acid (TACA), di-N-acetyldimethylglyoxin (ADMG) and 1-phenyl-3-acetylhydantoin (PAH).
- TAED N, N, N ', N'-tetraacetylethylene diamine
- GPA glucose pentaacetate
- TAX xylose tetraacetate
- SBOBS sodium 4-benz
- Layered silicates in particular smectites such as montmorillonites, saponites or hectorites with ion exchange capacities of preferably 50 to 100 meq / 100 g, as well as illites, attapulgites and kaolinites, serve as binders for the formation of the granules.
- smectites such as montmorillonites, saponites or hectorites with ion exchange capacities of preferably 50 to 100 meq / 100 g, as well as illites, attapulgites and kaolinites, serve as binders for the formation of the granules.
- Bentonites such as those sold under the names ⁇ Laundrosil DGA and Laundrosil EX 0242 from Süd-Chemie, Kunststoff (DE) are particularly preferred.
- layered silicates can also be used in acid-modified form, as are available in the commercial products ⁇ Tonsil EX 519, Tonsil Optimum 210 FF, Tonsil Standard 310 FF and 314 FF, and ⁇ Opazil SO from Süd-Chemie, Kunststoff (DE) stand.
- the granules according to the invention can also contain other auxiliaries, such as, for example, those which influence the pH during storage and use.
- auxiliaries such as, for example, those which influence the pH during storage and use.
- organic carboxylic acids or their salts such as citric acid in anhydrous or hydrated form, glycolic acid, succinic acid, maleic acid or lactic acid.
- additives which influence the bleaching capacity are also possible, such as complexing agents, polycarboxylates and iron or manganese-containing metal complexes, as described in EP-A-0 458 397 and EP-A-0 458 398.
- the weight ratio of ammonium nitrile to inorganic binder material is usually 50:50 to 98: 2, preferably 70:30 to 96: 4.
- the amount of any additives depends in particular on their type. For example, acidifying additives and organic catalysts for increasing the performance of peracid are used in amounts of 0 to 20% by weight, in particular in amounts of 1 to 10% by weight, based on the total weight. added, however, metal complexes in concentrations in the ppm range.
- the mixture of ammonium nitrile and binder is first mixed intimately in a mixing unit (eg ploughshare mixer). In a second step, the mixture becomes larger particles pressed. Roller compactors are suitable for this. The compacts are then subjected to comminution (grinding) and comminuted to the desired grain size. Toothed washer rollers and / or strainers are suitable for this purpose.
- Fine fraction and coarse material are screened off and returned to the process. While the coarse fraction is directly re-crushed, the fine fraction is added to the grain compacting stage.
- the grain size of the product is generally in the range from 100 to 2000 ⁇ m, preferably 300 to 1800 ⁇ m.
- the bulk density of the granules according to the invention is therefore above 500 kg / m 3 , preferably above 600 kg / m 3 .
- the granules obtained in this way are directly suitable for use in detergents and cleaning agents. In a special form of use, however, they can be provided with a coating envelope.
- the granules according to the invention are coated with a film-forming substance in an additional step, as a result of which the product properties can be significantly influenced.
- All film-forming substances such as waxes, silicones, fatty acids, soaps, anionic surfactants, nonionic surfactants, cationic surfactants, as well as anionic and cationic polymers, e.g. Polyacrylic acids.
- these coating materials i.a. the dissolving behavior is delayed in order to prevent interactions between the bending activator and the enzyme system at the beginning of the washing process. If the intended granulate is to be used in machine dishwashing detergents, waxes with melting points of 40 to 50 ° C are particularly suitable.
- Acidic coating materials increase and suppress the storage stability of the granules in highly alkaline formulations containing percarbonates Color damage due to spotting. Additions of a dye are also possible.
- the coating materials are generally applied by spraying the melted coating materials or coating materials dissolved in a solvent.
- the coating material can be applied in amounts of from 0 to 20, preferably from 1 to 10,% by weight, based on the total weight, on the granule core according to the invention.
- the products according to the invention are characterized by good storage stability in powder detergent, cleaning and disinfectant formulations. They are ideal for use in heavy-duty detergents, stain salts, machine dishwashing detergents, powdered all-purpose cleaners and denture cleaners.
- the granules according to the invention are used in combination with a hydrogen peroxide source in these formulations.
- a hydrogen peroxide source examples include perborate monohydrate, perborate tetrahydrate, percarbonates and hydrogen peroxide adducts with urea or amine oxides.
- the formulation can have further constituents, such as organic or inorganic builders and co-builders, surfactants, enzymes, optical brighteners and perfume.
