Definitions

  • the invention relates to dishwashing detergents, in particular for the automatic washing of dishes at low temperatures, which are distinguished by a high level of cleaning ability, in particular also in relation to stubborn and normally difficult to remove soiling, such as sebum / grease soiling, and by an extraordinarily low foaming ability.
  • alkaline cleaning agent mixtures are used for the automatic cleaning of dishes, which essentially consist of inorganic salts such as alkali phosphates, alkali silicates and alkali carbonates as well as active chlorine carriers and which, in order to improve the wetting effect, may contain minor additions of a low-foaming nonionic surfactant. These mixtures have a good cleaning ability against all stains at generally normal working temperatures of 55 to 65 ° C.
  • dishwashing detergent in addition to an enzyme mixture as cleaning enhancer, is primary, straight-chain or branched-chain C8-C10 alkanols, which may optionally be propoxylated, is added.
  • the invention therefore relates to agents for the mechanical cleaning of dishes based on polymeric alkali phosphates and / or their substitutes, alkali silicates, alkali carbonates and optionally active oxygen-releasing compounds and low-foaming nonionic surfactants, which are characterized in that they contain enzymes and primary, straight-chain or branched chain C8 -C10 alkanols, which may optionally be propoxylated, contain.
  • Suitable polymeric alkali metal phosphates are the condensed phosphates which are customarily used in detergent and cleaning agent mixtures and which may be present in the form of their alkaline neutral or acidic sodium or potassium salts. Examples include: tetrasodium pyrophosphate, disodium dihydrogen pyrophosphate, pentasodium triphosphate, sodium hexametaphosphate and the corresponding potassium salts or mixtures of sodium and potassium salts.
  • the water-soluble organic complexing agents for calcium are essentially found among the polycarboxylic acids, hydroxycarboxylic acids, aminocarboxylic acids, carboxyalkyl ethers, polyanionic polymeric carboxylic acids and the phosphonic acids, these compounds mostly being used in the form of their water-soluble salts.
  • Specific but not exhaustive examples are citric acid, carboxymethyl tartronic acid, mellitic acid, polyacrylic acid, poly- ⁇ -hydroxy acrylic acid, carboxymethyl malic acid, nitrilotriacetic acid and 1-hydroxy-ethane-1,1-diphosphonic acid.
  • Water-soluble sodium or potassium metasilicates are used as alkali metal silicates. They can be anhydrous, hydrated or contain water of crystallization and contain 5 to 9 moles of water.
  • Water glass is understood to mean water-soluble sodium or potassium silicates in which the ratio of alkali oxide to silicon dioxide is approximately 1: 2 to 1: 4. They can be used as anhydrous solid substances or as liquid, approximately 50% solutions.
  • Such enzymes are those of animal and vegetable origin, in particular active substances obtained from digestive ferment, yeast and bacterial strains. They usually represent a complex mixture of various enzymatic active ingredients. Of particular interest are enzymes that break down starches, proteins or fats, such as amylases, proteases and lipases.
  • the enzymes are obtained from a variety of processes from bacterial strains, fungi, yeast or animal organs and are sold under different names. Most of these are enzyme mixtures that have a combined effect on starch, protein and fats have.
  • the enzyme preparations obtained from Bacillus subtilis have the particular advantage for practical use that they are relatively resistant to alkalis. The temperature sensitivity of the enzymes no longer plays a significant role here.
  • the manufacturers set the enzymes to a certain degree of activity, optionally with the addition of blending agents such as sodium sulfate, sodium chloride, alkali phosphates or alkali polyphosphates.
  • blending agents such as sodium sulfate, sodium chloride, alkali phosphates or alkali polyphosphates.
  • LVE / g Löhlein-Volhard units per gram
  • IU international units
  • DE / g Device-g
  • the activity is often stated in LVE / g.
  • the proteolytic enzyme activity should be 100 to 5,000, preferably 200 to 2,000 LVE / g.
  • Amylolytic activity is generally reported in SKB / g (Sandstedt-Kneen-Blish units per gram). It should be about 5 to 1,000, preferably 15 to 250, SKB / g in the detergent mixture. The amount of the enzymes to be used in the dishwashing detergents depends on these values.
  • the primary, straight or branched chain alkanols contain 8 to 10 carbon atoms in the alkyl radical. They can be propoxylated with 1 to 2, preferably 2, moles per mole of alkanol propylene oxide. These include in particular n-octanol, 2-ethylhexanol, isononanyl alcohol, n-decanol, isodecanol and preferably n-octanol + 2 moles of propylene oxide (PO).
  • PO propylene oxide
  • alkali perborates, persulfates and percarbonate which can be activated by activators such as tetraacetylethylenediamine, tetraacetylglycoluril, pentaacetylglucose, but also compounds such as magnesium monoperphthalate, can be used as compounds which release active oxygen, but also compounds such as magnesium monoperphthalate, it being possible to dispense with the addition of activator.
  • activators such as tetraacetylethylenediamine, tetraacetylglycoluril, pentaacetylglucose, but also compounds such as magnesium monoperphthalate, can be used as compounds which release active oxygen, but also compounds such as magnesium monoperphthalate, it being possible to dispense with the addition of activator.
  • Preferred non-ionic low-foaming surfactants are ethylene oxide adducts with higher molecular weight polypropylene glycols with a molecular weight of 900 to 4,000, and ethylene oxide or. Ethylene oxide and propylene oxide adducts with C12-C18 alkanols and nonylphenol into consideration.
  • the preparation is carried out in a known manner by addition of the alkylene oxides in question in the presence of mostly alkaline catalysts, if appropriate under pressure and at elevated temperatures, it being possible to add up to three times the amount by weight of the starting compounds on alkylene oxides.
  • Suitable addition products are the adduct of 10% by weight of ethylene oxide with a polyoxypropylene glycol with a molecular weight of 1750, and the adduct of 9 mol of ethylene oxide and 10 mol of propylene oxide with nonylphenol, and the like.
  • the usable nonionic surfactants also include the surface-active amine oxides, which are mostly derived from tertiary amines with a hydrophobic C10-C20 alkyl group and two shorter alkyl and / or alkylol groups each containing up to 4 C atoms.
  • Typical representatives are, for example, the compounds N-dodecyl-N, N-dimethylamine oxide, N-tetradecyl-N, N-dihydroxyethylamine oxide or N-hexadecyl-N, N-bis (2,3-dihydroxypropyl) amine oxide.
  • the claimed mixtures may contain further components, in particular inorganic salts such as sodium sulfate, as a blending agent.
  • inorganic salts such as sodium sulfate
  • acidic or alkaline or buffering inorganic or organic compounds can be used to establish a pH value which is advantageous for the enzyme action.
  • the pH values are between 4 and 12, depending on the type of enzyme.
  • enzyme-activating additives such as ammonium chloride, sodium chloride, dyes, perfumes and the like, can also be added to the mixtures.
  • the claimed agents are generally used as mixtures of granular or powdery individual substances or as granulated, agglomerated or prilled products.
  • the claimed cleaning agent combinations are characterized by a high wetting effect and an extraordinarily good low-temperature cleaning ability, especially in relation to stubborn stains, such as grease, protein and starch deposits.
  • the application takes place by adding the powdered, granulated, agglomerated or prilled agents by hand into the dishwashing liquor or preferably by means of automatic dosing devices.
  • the application concentrations in the cleaning liquor should be about 2 to 7 g / l, temperatures of about 40 to 45 ° C. being used.
  • the test soils consisted of oatmeal porridge and starch in the form of mashed potatoes, which were placed on plates and scraped off. The dishes were then left to stand in the air for 6 hours at room temperature and then placed in the dishwasher.
  • the procedure for soiling beef tallow was as follows: 0.5 to 0.8 g of beef tallow were heated to liquefaction and approx. 2% titanium dioxide was stirred in. Then the still warm mass was spread evenly onto red plastic plates using a brush.
  • a conventional standard cleaning agent (A) was used, which had the following composition:
