Definitions

  • the laundry treatment generally requires several operations for "acidifying” (neutralizing) and “antichlorinating” (reducing) as well as softening or antibacterial treatment.
  • liquid aftertreatment agents which is usually desirable because of the metering devices for liquid agents which are usually present on commercial washing machines and which could be produced, for example, by dissolving powdery agents into a stock solution, usually fails because of the poor solubility or the insufficient stability of the solution or dispersion of the known aftertreatment agents intended for use in commercial laundries.
  • Known liquid agents do not have acidifying, antichlorinating and softening properties at the same time.
  • DE-OS 32 05 317 (EP-A-0.086.423) describes a liquid laundry aftertreatment agent which simultaneously combines textile softening, acidifying and antichlorizing properties.
  • the textile treatment agents disclosed here contain, in addition to quaternary ammonium compounds with a fabric softening effect, hydrogen peroxide or organic percarboxylic acids as reducing agents for chlorine and chlorine compounds with positive valency and additionally stabilizers for the peroxy compounds, in particular hydrogen peroxide.
  • acidifying agents in particular phosphoric acid or acidic salts of phosphoric acid, but also other inorganic and / or organic acids or salts, the pH of the agent is reduced to such an extent that it is at most 4.
  • These agents of DE-OS 32 05 317 can also contain other conventional additives, for example antibacterial agents.
  • additives for example antibacterial agents.
  • examples of other additives are dispersants, foam regulators and colorants and fragrances.
  • Water may be considered as the liquid carrier with the addition of organic water-miscible solvents.
  • DE-A-3142767 shows that aqueous peroxide solutions are stabilized to a certain extent by hexafluorosilicic acid.
  • the invention is based on the task of further improving the means described last.
  • the invention aims to extend the shelf life and thus the useful life of such agents.
  • the substance mixture of the type described contain per-compounds as an essential constituent, in particular hydrogen peroxide.
  • hydrogen peroxide quaternary ammonium compounds and an acidic agent, in particular phosphoric acid or phosphoric acid salts
  • an acidic agent in particular phosphoric acid or phosphoric acid salts
  • extremely stable solutions can already be assembled in the presence of a complexing agent for heavy metal ions.
  • further studies have shown, surprisingly, that when very specific acidic agents are used or used, a substantial change in the storage stability and thus the useful life of agents of the type described can be achieved.
  • the invention relates in a first embodiment to liquid laundry aftertreatment agents with textile softening, acidifying and antichlorizing properties, containing hydrogen peroxide or an organic percarboxylic acid, stabilizers for peroxide compounds, textile softening quaternary ammonium compounds and acidifying agents and, if desired, other customary additives, in acidic aqueous solution.
  • the characteristic of the new teaching lies in the fact that, as an acidifying agent, at least partially Magnesium salt of hexafluorosilicic acid is present.
  • the amount of the magnesium salt of hexafluorosilicic acid in the laundry treatment composition is preferably about 1 to 25 percent by weight, in particular about 5 to 20 percent by weight.
  • hexafluorosilicic acid or its salts are the sole or predominant constituent for acidifying the treatment agent, it also being preferred here not to set pH values above 4 in the aqueous aftertreatment agent.
  • Very particularly suitable amounts of these acidifying agents are in the range from about 8 to 18 percent by weight.
  • the quaternary ammonium compounds with preferably two long-chain, preferably saturated aliphatic radicals each having 14 to 26, preferably 16 to 20 carbon atoms and at least one quaternary nitrogen atom in the molecule are suitable as fabric softening agents.
  • the long-chain aliphatic radicals can be straight-chain or branched and can accordingly be derived from fatty acids or from fatty amines, Guerbetamines, or from the alkylamines obtainable by reduction of nitroparaffins.
  • These quaternary ammonium compounds are, in particular, derivatives of ammonia, i.e.
  • the quaternary salts obtainable by alkylation of long-chain secondary amines, such as, for example, the compounds distearyldimethylammonium chloride or ditalgalkyldimethylammonium chloride, or the reaction of 1 mol of an aminoalkylethylenediamine or hydroxyalkylethylenediamine with 2 mol a long-chain C 12 -C 26 fatty acid or its ester obtainable imidazoline compounds which are subsequently converted into the quaternary imidazolinium compounds by alkylation.
  • the anion generally consists of the acid residue which has arisen from the alkylating agent used in the quaternization.
  • chloride, bromide, methyl sulfate, ethyl sulfate, methane, ethane or toluenesulfonate are suitable as anions.
  • condensation products of 1-3 moles of fatty acid alkyl ester or 1/3 to 1 mole of fatty acid triglyceride with 1 mole of a hydroxyalkylpolyamine, for example hydroxyethylethylenediamine or hydroxyethyldiethylenetriamine are also suitable as textile softeners.
  • the product obtained by reacting 1 mol of a fatty acid triglyceride, in particular hardened tallow, with 1 mol of hydroxyethylethylenediamine at 90-150 ° C. is particularly suitable.
  • these active ingredients lead to a uniform, striking improvement in the grip and, at the same time, an antistatic finish without staining.
  • the agent according to the invention preferably contains hydrogen peroxide (H 2 0 2 ) as an antichlorinating component.
  • H 2 0 2 acts as a reducing agent compared to the stronger oxidizing agent hypochlorite.
  • organic percarboxylic acids such as diperazelaic acid or diperisophthalic acid can also be used.
  • the hydrogen peroxide is preferred because of its easy accessibility and because it is converted to the water which is present anyway upon reduction. Another advantage of the H 2 0 2 is that it cannot form solid deposits.
  • the agent contains a heavy metal complexing agent.
  • Suitable complexing agents are e.g. Alkane polyphosphonic acids, amino and hydroxyalkyan polyphosphonic acids and phosphonocarboxylic acids, e.g. the compounds methane diphosphonic acid, 1-aminoethane-1,1-diphosphonic acid, aminotrimethylene triphosphonic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid and 1-hydroxyethane-1,1-diphosphonic acid or aminopolycarboxylic acids such as e.g.
  • Nitrilotriacetic acid, ethylenediaminetetraacetic acid or hydroxyethylethylenediamine triacetic acid or their alkali salts Such heavy metal complexing agents also counteract a yellowing tendency of the laundry caused by heavy metal ions in the rinse water.
  • 1-Hydroxyethane-1,1-diphosphonic acid and its alkali salts have a particularly good stabilizing effect.
  • inorganic and / or organic acids or corresponding acidic salts can also be used.
  • additional acids or acidic salts are preferred, which do not in turn interact with the peroxide.
  • orthophosphoric acid and / or its acidic salts for example sodium dihydrogenphosphate.
  • the agents according to the invention can contain customary further additives.
  • Antimicrobial agents are an example of this.
  • bactericidal or bacteriostatic or fungicidal or fungistatic compounds are understood.
  • These active ingredients are said to be water-soluble either as such or in the form of their salts.
  • the antimicrobial active substances which are suitable as additives are, for example, those quaternary ammonium compounds which, in addition to a long-chain aliphatic and two short-chain aliphatic hydrocarbon radicals, contain an aromatic radical in the molecule which is linked to the nitrogen atom via an aliphatic carbon atom or an aliphatic organic bond which has double bonds.
  • antimicrobial quaternary ammonium compounds are the following: dimethylbenzyldodecylammonium chloride, dimethyl benzyl-tetradecylammonium chloride, dimethyl- (ethylbenzyl) -dodecyl-ammonium chloride, dimethylbenzyldecylammonium bromide, diethyl-benzyl-dodecylammonium chloride, diethyl-benzyl-octylammonium chloride, dibutyl-allyl-, methyl-ethyl-benzyl, ethyl-ethyl-cyclo-ethyl-ethyl-cyclo -dodecyl-ammonium chloride and in particular coconut alkyl dimethyl benzyl ammonium chloride. Dimethyldidecylammonium chloride is also effective.
  • antimicrobial agents can also be used, provided they are stable in the presence of per compounds in an acidic medium.
  • betaines such as Dodecyl-di (aminoethyl) glycine.
  • Other useful antimicrobial agents are e.g. Hexamethylene bis (chlorophenyl) biguanide digluconate or dihydrochloride and dodecylglycine.
  • nonionic surfactants are particularly suitable as dispersants, as they can be contained in the liquid textile aftertreatment agents according to the invention. These include products that owe their hydrophilic properties to the presence of polyether chains, amine oxide, sulfoxide or phosphine oxide groups, alkylolamide groups or, quite generally, an accumulation of hydroxyl groups.
  • nonionics contain at least one hydrophobic radical with 8-26, preferably 10-20 and in particular 12-18 carbon atoms in the molecule, and at least one nonionic, water-solubilizing group.
  • the preferably saturated hydrophobic residue is usually aliphatic, possibly also alicyclic in nature; it can be connected to the water-solubilizing groups directly or via intermediate links.
  • Intermediate links are e.g. Benzene rings, carboxylic acid ester or carbonamide groups, ether or ester-like radicals of polyhydric alcohols, such as e.g. that of ethylene glycol, propylene glycol, glycerol or corresponding polyether residues in question.
  • Typical nonionics which are preferred as dispersants are. e.g. the adducts of about 9 moles of ethylene oxide with nonylphenol or with dodecyl alcohol, polyethylene glycols with up to 50-ethoxy units or polyethoxy-polypropoxy-glycols with up to 20 ethoxy or propoxy units.
  • the quaternary ammonium compound which softens the textile is preferably in particular the compounds Dimethylditalgalkylammoniumchlorid or Dimethyldiestearylammoniumchlorid used on a large scale, of which Dimethyldistearylammoniumchlorid is particularly preferred.
  • Quaternary ammonium compounds are preferred as antibacterial active substances, in particular coconut alkyldimethylbenzylammonium chloride.
  • hydrogen peroxide which has sufficient stability in the presence of heavy metal complexing agents, is used for the antichlorination.
  • Suitable heavy metal complexing agents by means of which both the hydrogen peroxide is stabilized and a discoloration of the laundry is counteracted by the use of washing water and rinsing water with a content of heavy metal ions which is intrinsically disruptive, are in particular alkane polyphosphonic acids and aminopolycarboxylic acids, in particular hydroxyethylenediaminotrieslacetic acid and / or 1- Hydroxyethanol, 1-diphosphonic acid or their alkali salts.
  • Agents according to the invention advantageously contain a small amount, for example 0.5-5% by weight, of nonionic surfactants as a dispersant, especially when larger amounts of textile-softening quaternary ammonium compounds are used to achieve a pronounced softening effect.
  • the invention further relates to a method for simultaneous softening, for removing active chlorine and for neutralizing alkaline detergent residues and optionally for antibacterial finishing of freshly washed laundry.
  • the process is characterized in that the washing in the last rinse cycle with 0.5 to 20 g per liter of an agent of the composition described above, which is added to the rinsing bath, for 0.5-5 minutes with constant movement at about 10 to 30 ° C treated.
  • the treatment liquor is then separated, for example by squeezing or centrifuging down to a residual moisture content of approx. 10 to approx. 100% by weight, based on the dry weight of the laundry.
  • the laundry is then dried in a tumble dryer, for example, and ironed if necessary. It has a soft handle after drying.
  • This substance mixture which corresponds to the teaching of DE-OS 32 05 317, is compared with regard to its degree of hydrogen peroxide storage during storage for 12 weeks at 40 ° C. compared with the active substance mixtures according to the invention summarized in the following table under numbers 2 to 5.
  • magnesium hexafluorosilicate is used here as an acidifying agent.
  • the superior effect of the active ingredient mixtures according to the invention with regard to the degree of H 2 0 2 conservation after storage at 40 ° C. for 12 weeks can be seen from the corresponding numerical values.
  • the numerical values of the mixtures according to 2, 4, 5 and 6 are in the range 79-88% H 2 0 2 Conservation compared to 28.5% for the active ingredient mixture according to the prior art.
  • Even the active ingredient mixture 3 used for the comparison which contains no complexing agent but contains magnesium fluorosilicate, is still significantly better in the H 2 0 2 degree of preservation than the substance mixture of the prior art used for the comparison.
  • the active ingredient mixtures according to the invention are generally placed in the last rinsing bath of a commercial washing machine, depending on the implementation of the previous washing process, i.e. of the remaining residual alkali or the desired softening or microbicidal effect - in an amount of 1 to 5 g / l to the rinse water (temperature approx. 25 ° C) and treat the washed and bleached with hypochlorite laundry for approx. 2 minutes. After this treatment liquor has been spun off, it can be determined by measuring the pH of the adhering moisture that alkaline detergent residues on the laundry are neutralized. The laundry does not smell of chlorine. After drying, it has a soft full grip.
