Definitions

  • the present invention relates to an agent which contains inorganic per-compound and an activator for this per-compound and which can be used in an aqueous solution for bleaching and disinfecting a wide variety of materials, but is preferably used for treating textiles.
  • Inorganic per-compounds such as sodium perborate and sodium percarbonate, which release hydrogen peroxide when dissolved in water, only have sufficient bleaching and disinfecting activity in dilute aqueous solution, just like the hydrogen peroxide itself, above about 80 ° C.
  • activators As a rule, these are N-acyl or 0-acyl compounds which react in aqueous solution with hydrogen peroxide to give percarboxylic acids, which are then to be regarded as the actual active substances. Accordingly, agents have been proposed for use at low temperatures, which essentially consist of a combination of inorganic per-compound and suitable activator, optionally together with other auxiliaries and additives.
  • European patent applications 268 170 and 427 314 are to be mentioned here, for example.
  • DE-A-42 32494 discloses granular bleach activator compositions consisting of a water-soluble core agent, a bleach activator and a water-soluble organic binder. This granulate can in turn be provided with an organic coating layer.
  • the proposals for protecting the activator substances during storage are extremely numerous and range from coating the activator material with molten fatty acids and cooling the drops formed, to producing fine-particle extrudates consisting of mixtures of activators and wax-like hydrophobic materials, and compacting them of mixtures of activators and coating substances between rollers and subsequent comminution of the slug.
  • the agglomeration of finely divided activator material with the aid of water-soluble or alkali-soluble polymer compounds has become particularly important because the granules produced in this way have good storage stability on the one hand, but their solubility is practically not impaired on the other.
  • the granules which contain more than 90% activator, as described, for example, in European patent applications 37 026, 70 474, 356 700 and 468 824, have proven to be particularly advantageous.
  • the invention relates to a granular bleach and disinfectant which contains an inorganic per-compound, a granulated activator and a carrier material, the activator granules contained by agglomeration of finely divided activator material (a) with the aid of water- or alkali-soluble polymers (b) in a ratio of a: b greater than 90:10 and was sprayed before mixing with the inorganic per compound and the carrier material with an organic compound from the group of nonionic surfactants, long-chain alcohols, polyethylene glycols, fatty acids, waxes and their mixtures melting between 30 and 100 ° C .
  • the activator granules preferably contain 1 to 25% by weight, in particular 2 to 10% by weight, of the organic compound melting between 30 and 100 ° C.
  • bleach activators or perborate activators are acylating agents which are capable of acylating hydrogen peroxide to peroxycarboxylic acids in dilute aqueous solution.
  • activators are suitable for the agents according to the invention insofar as they are compounds which are present in the solid state at the usual storage temperatures of bleaching and disinfecting agents.
  • Tetraacetylethylenediamine (TAED), pentaacetylglucose and 1,5-diacetylhexahydro-1,3,5-triazine-2,4-dione are particularly preferred.
  • TAED Tetraacetylethylenediamine
  • pentaacetylglucose and 1,5-diacetylhexahydro-1,3,5-triazine-2,4-dione are particularly preferred.
  • TAED Tetraacetylethylenediamine
  • polymers which are soluble in water or in a weakly alkaline aqueous medium.
  • Suitable are natural polymers, such as starch or other carbohydrates, as well as chemically modified carbohydrates and fully synthetic polymers.
  • modified carbohydrate-based polymers are cellulose and starch ethers, such as, for example, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, methyl hydroxyethyl cellulose, Methyl hydroxypropyl cellulose, carboxymethyl cellulose (as sodium salt), methyl carboxymethyl cellulose (sodium salt), carboxymethyl starch, hydroxyethyl starch and methyl starch.
  • ethers sodium carboxymethyl cellulose has proven to be particularly suitable.
  • Polymers and copolymers of olefinically unsaturated carboxylic acids in particular acrylic acid, methacrylic acid and maleic acid or their salts, can be used as synthetic polymers.
  • copolymers can consist exclusively of olefinically unsaturated carboxylic acids or, in addition to olefinically unsaturated carboxylic acids, can also contain nonionic monomers such as, for example, vinyl ethers, vinyl esters, amides of olefinically unsaturated acids and olefins.
  • water-soluble polymers with a carbon chain for example partially saponified polyvinyl acetate, polyvinylpyrrolidone and polyacrylamide, can also be suitable.
  • the content of water- or alkali-soluble polymers in the activator granules before spraying with the low-melting organic compound is preferably between 0.5 and 8% by weight, in particular between 2 and 5% by weight.
  • activator granules are used for the agents according to the invention, which are produced by agglomeration of finely divided activator material with the aid of water or alkali-soluble polymers in a weight ratio greater than 90:10.
  • the weight ratio of activator material to polymers is preferably between 91: 9 and 99: 1.
  • Activator granules which contain more than 90% by weight of activator and between 2 and 5% by weight of polymer before spraying are particularly preferred.
  • the activator granules used according to the invention are usually largely free of hydratable salts, ie they contain less than 4% by weight, preferably less than 2% by weight.
  • a characteristic of the agents according to the invention is the presence of a low-melting organic compound which is subsequently sprayed onto the granular activator made from finely divided activator material and water- or alkali-soluble polymers.
  • organic compounds from the group of nonionic surfactants are organic compounds from the group of nonionic surfactants, long-chain alcohols, polyethylene glycols, fatty acids, waxes and mixtures of these compounds.
  • the long-chain alcohols are preferably fatty alcohols with 14 to 20 C atoms and linear 1,2-diols with a similar chain length.
  • suitable individual compounds from the aforementioned group are palmitic acid, stearic acid, tetradecanol-1, decanediol-1,2, beeswax and carnauba wax.
  • nonionic surfactants preference is given to using nonionic surfactants, and of these in turn the addition products of long-chain alcohols and ethylene oxide (E0) and, if appropriate, propylene oxide (P0) are particularly preferred.
  • these addition products are tallow alcohol +5 EO and tallow alcohol + 40 EO.
  • the organic compounds melting between 30 and 100 ° C. may contain other organic compounds, for example anionic surfactants such as alkylbenzenesulfonate or alkyl sulfate in solution.
  • the organic compounds melting between 30 ° C and 100 ° C are sprayed in liquid form onto the prefabricated activator granules. Their proportion is such that the amount of these compounds, based on the activator granules treated in this way, is preferably 1 to 25% by weight, in particular 2 to 10% by weight. The amount can be selected regardless of whether or not it creates a closed coating on the original granules, since a closed coating does not appear to be necessary for the desired success.
  • the parameters of the process step in particular the selection of the device type, the mechanics and the residence time of the granules, must be aligned with this goal.
  • Suitable devices in which spraying can take place are, in particular, devices in which the granules are moved mechanically or pneumatically.
  • the dwell time in these devices is kept as short as possible and is usually not more than 10 minutes, preferably between 1 and 4 minutes. Post-mixing after the spraying process has ended is generally avoided, and the devices are also emptied as quickly and gently as possible. If work is carried out in mixing units, it is also possible to carry out the mixing of the inorganic per compounds and the carrier material and, if appropriate, further constituents of the agent in the same mixer after spraying the granules immediately after spraying the activator granules or after observing a certain cooling period. In the other case, the production of the finished agent is carried out in a downstream mixing unit. In order to avoid the creation of dust, work is usually carried out with low energy input.
  • Suitable inorganic per-compounds for the agents according to the invention are those solid per-compounds which release hydrogen peroxide when dissolved in water.
  • examples of such inorganic per compounds are sodium perborate tetrahydrate, sodium perborate monohydrate, sodium percarbonate and urea perhydrate.
  • Perborate tetrahydrate, perborate monohydrate and percarbonate as well as mixtures of these per compounds, but especially perborate monohydrate, are particularly preferred within the scope of the agents according to the invention.
  • the per compounds can be used in pure form or, usually, in technical quality, with stabilizers frequently being added, particularly in the case of sodium percarbonate, which are intended to delay the decomposition of the per compound during storage.
  • the content of inorganic Per compounds in the agents according to the invention are preferably between about 30 and about 70% by weight, preferably between 40 and 60% by weight. It depends, among other things, on the active oxygen content of the per compound chosen. Perborate monohydrate 40 to 50 wt .-% are particularly preferred.
  • the agents according to the invention contain, as the third major component, an inert, non-hydrating and non-hygroscopic filling material, which is to be referred to here as the carrier material.
  • This material has various auxiliary tasks, such as, for example, improving the flowability, the desensitization of the mixture of per compound and organic material and, if appropriate, the setting of the suitable pH after dissolving in water.
  • Suitable carrier materials are, for example, urea, sodium aluminum silicate (zeolite) and sodium hydrogen carbonate. Sodium bicarbonate is particularly preferred in the context of the present invention.
  • the amounts of carrier material in the agents according to the invention are preferably between about 10 and about 40% by weight, in particular between 20 and 30% by weight.
  • the agents according to the invention can contain further auxiliaries and additives, if this is necessary in the individual case.
  • auxiliaries are substances for improving the flushing-in behavior when the agents are flushed into the water flow via an automatic metering device, stabilizers for reducing the peroxide decomposition during storage, additives for dust binding, and surfactants for improving the wetting effect.
  • Substances to improve the induction behavior are optionally used in amounts between 0.5 and 2%, based on the finished agent. Calcium stearate is preferably used for this purpose.
  • Preferred peroxide stabilizers are polyphosphonic acids and their salts, for example the sodium salts of hydroxyethane diphosphonic acid, ethylenediaminetetramethylenephosphonic acid and diethylenetriaminepentamethylenephosphonic acid, and also gluconic acid and its salts.
  • Dust-binding agents are usually used after mixing together all components of the agent also applied in a spray process.
  • Nonionic surfactants which are liquid at room temperature are preferably used here, but other known dust binders may also be suitable for this purpose.
  • 0.5 to 5% by weight, based on the total composition, of nonionic surfactants is preferably applied.
  • the agents according to the invention contain inorganic per-compounds, activator and carrier material in an optimally coordinated form, so that when they are dissolved in water, bleaching and disinfection solutions can be prepared in ready-to-use form.
  • the solutions can be used as such for bleaching and disinfecting a wide variety of objects. However, they are preferably used for bleaching and disinfecting textile materials, in particular during a washing process.
  • the detergents are metered into the wash liquor in sufficient quantities by hand or automatically, with an overdose not being necessary for safety reasons because of the stability of the detergents according to the invention against segregation. This quality of the agents therefore has a particularly advantageous effect in commercial use in large laundry, for example when washing hospital laundry.
  • a granulate of tetraacetylethylene diamine (TAED) was used as the starting material for the production of the bleaching and disinfectant, which had been prepared according to EP 37 026 by agglomeration of finely divided TAED with the aid of 4.7% by weight sodium carboxymethyl cellulose (based on granulate).
  • the granules contained no further components apart from 0.5% by weight of water.
  • the average grain size was 0.7 mm.
