Definitions

  • agents with acidic and / or reducing constituents by means of which disruptive detergent and bleach residues are converted into non-disruptive compounds, are added to the last rinsing bath.
  • washed laundry has a pleasantly soft feel after drying; this is especially true for laundry that lies on the skin and for terry towels.
  • bacteriostatic finishing of the textiles e.g. B. roll towels required.
  • 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 desirable because of the metering devices for liquid agents 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.
  • the agents known from US 4,166,794 contain EDTA as a stabilizer for per compounds.
  • Another disadvantage of many known agents is e.g. B. also in the deposition of salt-like components of these agents on the textiles, whereby the wearing properties and durability of the textiles are impaired.
  • these deposits if they get into the trough of a lack of laundry, can lead to faults there.
  • the object of this invention is therefore to provide a liquid laundry aftertreatment agent with fabric softening, acidifying and antichlorizing properties, comprising a fabric softening quaternary ammonium compound, an acidic compound and a reducing agent.
  • a liquid laundry treatment agent with fabric softening, acidifying and. antichlorinating properties containing a quaternary ammonium compound which softens the textile, an inorganic or organic acid or acid salts, hydrogen peroxide or organic percarboxylic acids as reducing agent for chlorine and chlorine compounds with positive valency and additionally a stabilizer for peroxy compounds, which is characterized in that the stabilizer 1-Hydroxyethane-1,1-diphosphonic acid and / or hydroxyethylenediaminetriacetic acid or its alkali metal salts, with the proviso that the amount of the acidic compound is selected so that the pH of the agent is at most 4.
  • the agent can contain antibacterial agents.
  • conventional additives such as. B. dispersants, foam regulators, colors and fragrances may be included in the agent.
  • Water can be used as the liquid carrier, possibly with the addition of small amounts of organic solvents.
  • agent according to the invention for post-treating washed laundry, it is possible at the same time to neutralize alkaline detergent residues that adhere to the laundry after the washing and rinsing process, to reduce hypochlorite bleach residues, to give the laundry items a pleasantly soft feel and antistatic behavior after drying confer and if necessary to make them antibacterial, while at the same time the formation of deposits on the textiles is reduced.
  • the agent according to the invention can also be conveniently and precisely dosed automatically.
  • the quaternary ammonium compounds with preferably two long-chain, preferably saturated aliphatic radicals each having 14-26, preferably 16-20, 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, ie the quaternary salts obtainable by alkylation of long-chain secondary amines, such as, for. B.
  • 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 1/3-1 mole of fatty acid triglyceride with 1 mole of a hydroxyalkyl polyamine, for example hydroxyethyl ethylene diamine or hydroxyethyl diethylene triamine 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.
  • Acidic compounds include inorganic acids, such as, in particular, orthophosphoric acid, acidic salts of orthophosphoric acid, such as, for. As sodium dihydrogen phosphate, non-surfactant organic acids with 1-8 carbon atoms, such as.
  • Glycolic acid, citric acid, formic acid, acetic acid, lactic acid, tartaric acid are preferred organic acids because of their easy accessibility and non-toxicity.
  • a mixture consisting of adipic acid, glutaric acid and succinic acid can also be used as an acidic additive.
  • the particularly preferred orthophosphoric acid (H 3 P0 4 ) can also be used together with sodium dihydrogen phosphate as an acidifying agent.
  • the agent according to the invention contains so much acidic additives that the pH of the agent is at most 4. Depending on the desired acidification effect, the agent contains different amounts of acidic substances, so that the pH is also significantly lower, e.g. B. may be 1 or below.
  • 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. B. diperazelaic acid or diperisophthalic acid can 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 1-hydroxyethane-1,1-diphosphonic acid and / or hydroxyethylene diamine triacetic acid or its alkali metal salts as a stabilizer.

These active ingredients are said to be water-soluble either as such or in the form of their salts.
  • the antimicrobial agents suitable as additives are e.g. For example, such quaternary ammonium compounds which, in addition to a long-chain aliphatic and two short-chain aliphatic hydrocarbon radicals, contain an aromatic radical linked via an aliphatic carbon atom to the nitrogen atom, or an aliphatic organic radical having double bonds in the molecule.
  • antimicrobial quaternary ammonium compounds are the following: dimethylbenzyldodecylammonium chloride, dimethylbenzyltetradecylammonium chloride, dimethyl (ethylbenzyl) dodecylammonium chloride, dimethylbenzyldecylammonium bromide, diethylbenzyldodecylammonium chloride Dibutylallyl, methyl-ethyl-benzyl, ethyl-cyclohexyl-allyl, ethyl-crotyldiethylaminoethyl-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. B. Dodecyl di (aminoethyl) glycine.
  • Other useful antimicrobial agents are e.g. B. 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, in general, an accumulation of hydroxyl groups.
  • nonionics contain at least one hydrophobic radical with 8 to 26, preferably 10 to 20 and in particular 12 to 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 with the water-solubilizing groups directly or via Intermediate links.
  • intermediate links come z. B. benzene rings, carboxylic acid ester or carbonamide groups, ether or ester-bonded residues of polyhydric alcohols, such as. B. that of ethylene glycol, propylene glycol, glycerol or corresponding polyether radicals in question.

  • Remainder water and optionally small amounts of dispersants, foam regulators or other conventional additives.
  • the quaternary ammonium compound which softens the textile is preferably in particular the compounds Dimethylditalgalkylammoniumchlorid or Dimethyldistearylammoniumchlorid 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 in particular for the antichlorination.
  • Suitable stabilizers by 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 disruptive are hydroxyethylene diaminotriacetic acid and / or 1-hydroxyethanl, 1-diphosphonic acid or the like Alkali salts.
  • Agents according to the invention advantageously contain small amounts, for example 0.5-5% by weight, of nonionic surfactants as dispersants, if 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.
