Definitions

  • the invention relates to a surfactant-containing mixture for the mechanical cleaning of hard surfaces, in particular bottles and dishes, in the alkaline to highly alkaline range of the cleaning liquor.
  • the system must also be as little or as little foam as possible, since excessive foam formation can lead to malfunctions in the operating behavior of the system, for example if the dirt that accumulates in the foam layer cannot be discharged sufficiently. Additional tendencies towards foam formation are caused by the impurities carried into the fleet by the items to be cleaned, in particular by protein-containing residues on the items to be cleaned. In the case of bottle cleaning, this also applies in particular to the labels to be removed, which are introduced into the cleaning liquor through the glue residues and residues of printing inks, including the surfactant auxiliaries contained in the latter.
  • non-ionic surfactants with a low-foaming characteristic as cleaning agents for hard surfaces in alkaline baths.
  • These are, in particular, addition products of ethylene oxide and / or propylene oxide onto amines, longer-chain fatty alcohols or alkylphenols, polyglycol ether formals or acetals or block copolymers of ethylene and propylene oxide.
  • Such surfactant systems can be adjusted, in particular, by suitable variation of the ethylene oxide and propylene oxide proportions to the lowest possible foam tendency and increased cleaning action, an excess weight of the propylene oxide favoring the former property and an excess weight of the ethylene oxide promoting the latter property.
  • the ratio of the ethylene oxide to propylene oxide units should preferably be in the range from 0.8 to 2.
  • a 3 also a polyalkylene glycol dialkyl ether of the formula be, which contains ethylene oxide and optionally propylene oxide units, which can be arranged randomly or in blocks.
  • R 1 is an alkyl radical with 6 to 22 carbon atoms, preferably with 8 to 18 carbon atoms
  • R 3 is an alkyl radical with 1 to 4 carbon atoms, preferably the tert-butyl radical
  • c is a statistical mean in the range from 5 to 20, preferably from 6 to 14
  • d has a statistical mean in the range from 0 to 3, preferably 0.
  • non-ionic surfactants can also be present as mixtures within groups A 1 ), A 2 ) or A 3 ) or else between groups A 1 ), A 2 ) and / or A 3 ).
  • the non-ionic surfactants of group A 1 ) are preferred.
  • the surfactant mixture contains a quaternary ammonium compound B of the formula as a cationic component in which R 4 and R 5 , identical or different, are an alkyl radical with 1 to 12 C atoms, preferably with 4 to 8 C atoms, in particular with 4 to 6 C atoms, R 6 is an alkyl radical with 1 to 8 C atoms Atoms, preferably 1 to 6 carbon atoms, and R 7 is an alkyl radical with 1 to 4 carbon atoms or a benzyl radical.
  • A is an anion, preferably a chloride or bromide anion or one of the formula CH 3 0S0 3 -.
  • Rf is a CF 3 - or (CF 3 ) 2 -CF radical
  • R 8 is a lower alkyl radical
  • R 9 is hydrogen or a lower alkyl radical (with a lower alkyl radical here being one with 1 to 3 carbon atoms, preferably a methyl - or ethyl radical should be understood)
  • e is an integer from 5 to
  • f is an integer from 0 to 4
  • these fluorinated alcohols are advantageously introduced in a mixture with a solubilizer in which they have been predissolved. This is especially true when very small amounts of the fluorinated alcohol are to be used.
  • a suitable solubilizer must be completely or at least largely homogeneously miscible with the surfactant mixture A + B or its single components.
  • the fluorinated alcohol C) should be largely or entirely soluble in this solubilizer.
  • An effective amount of such a solubilizer is preferably 1 to 1,000 parts by weight per 1 part by weight of the fluorinated alcohol; however, this effective amount should not exceed 20% by weight of the total weight of components A + B.
  • solubilizers are aliphatic ketones, such as dimethyl and diethyl ketone.
  • Carboxylic acid esters of aliphatic alcohols and diols such as ethyl acetate, isobutyl ester, ethylene glycol acetate, 2-ethylhexyl-2-ethylhexanoic acid ester, acid amides of longer-chain carboxylic acids, such as, for example, N- (2-ethylhexyl) -isononanoic acid amide, polypropylene glycols with molar weights of> 600 and mixed units of molecular weights> 600 and propylene oxide, ethylene and propylene glycol monoethers and the corresponding polyglycol ethers, such as methyl, ethyl and butyl monoethers of di, tri and tetraethylene glycol.
  • Alkanols with 1 to 9 carbon atoms in a straight or branched chain should
  • the surfactant-containing mixtures according to the invention can be used as a mixture of components A + B + C., optionally including the solubilizer, in undiluted, liquid form. However, they can also be used in the form of aqueous concentrates, for example for better meterability, if appropriate also with the addition of an organic solvent. that is not a solution broker in the above sense.
  • components A and B can also first be added individually or together to the aqueous cleaning liquor and the fluorinated alcohol C can be metered in, in which case a solubilizer must be present.
  • component C can also be introduced premixed with one of the two components A or B, the other being subsequently metered in.
  • the application concentration is advantageously 0.05 to 10 g of the surfactant mixture A + B (without inclusion of C) per liter of cleaning liquor, preferably 0.1 to 2 g per liter.
  • Such application concentrations are non-critical statements, since the amount depends to a certain extent on the type of surface to be cleaned and on the type and extent of the contaminants.
  • the surfactant mixtures according to the invention can optionally be used in the preparation commercially available formulations further additives and auxiliaries are added. These include dyes, fragrances, corrosion inhibitors and disinfectants.
  • auxiliaries include dyes, fragrances, corrosion inhibitors and disinfectants.
  • the known builders which are optionally also complexing agents, should also be mentioned here.
  • the condensed phosphates such as tripolyphosphates and in particular pentasodium triphosphate, come into consideration.
  • these are complex-forming aminopolycarboxylic acids and their salts, such as, in particular, alkali metal salts of nitrilotriacetic acid and ethylenediaminetetraacetic acid, and also also complex-forming hydroxycarboxylic acids and polymeric carboxylic acids, such as citric acid, tartaric acid and the like.
  • Another class of complexing builders are polyphosphonic salts, such as the alkali salts of aminophosphonic acid.
  • builders, such as silicates, for example sodium metasilicate, carbonates, bicarbonates, borates and citrates can also be added. With the aid of such additives, the mixtures according to the invention can optionally be converted into powder form and can also be used in this form.
  • the surfactant-containing mixtures according to the invention are suitable for the mechanical cleaning of hard surfaces in alkaline liquors. This applies to cleaning in household dishwashers and so-called commercial cleaning systems.
  • the mixtures are particularly suitable for industrial cleaning systems for hard surfaces, for example dishwashing and bottle washing systems, which operate under high mechanical liquor movements in continuous operation and in highly alkaline liquors at pH values of 2-t 10, preferably 2-e 12.
  • the necessary alkaline additives preferably sodium or potassium hydroxide for the highly alkaline pH range of the liquor, can be dissolved in the aqueous cleaning liquor before the surfactant-containing mixture according to the invention is introduced. However, they can also be added directly to the mixture and metered together with it.
  • the alkaline agent is expediently added in the form of powder, flakes or cookies.
  • the mixtures according to the invention have an extremely low tendency towards foaming which is indispensable for industrial cleaning systems. It is essential that the fluorinated alcohol C used as an anti-foaming agent is absolutely stable in the highly alkaline range. By adding it it is achieved that even with extremely high mechanical liquor movements, such as occur, for example, in the bottle cleaning systems of breweries, there is practically no foam formation. The tendency towards foaming is also reduced to a minimum, even with heavily to extremely foam-promoting soiling, such as protein, milk, beer, lemonade, glue and surfactant components from labels.
  • the surfactant-containing mixtures have this extraordinarily low tendency to foam formation not only at the working temperatures of such cleaning systems, that is above about 40 ° C, but also at low temperatures, so that when refilled with cold water and heating, no disruptive foam is formed, which then leads to Overflowing or disturbing the circulation of the system.
  • the surfactant mixtures according to the invention as cleaning agents for the mechanical cleaning of hard surfaces, in particular with regard to the high demands placed on industrial cleaning systems, also have the following significant advantages: the mixtures are not only resistant to alkali, but also long-term storage stability with alkali.
  • the excellent dirt absorption capacity allows long service life in the system until it is refilled without impairing the cleaning effect.
  • Good wetting capacity and drainage behavior enable dirt to be removed quickly and thus a high throughput of items to be cleaned. The freedom from stains and streaks as well as high gloss of the cleaned goods is also guaranteed.
  • the dirt absorption limit by checking the foaming capacity with increasing dirt load is determined by gradually adding a test foamer to the cleaning liquor.
  • a whisked egg is used as the test frother, which is added in portions of 0.2 g / l of liquor.
  • the dirt absorption limit is recognizable by a sudden foam increase in the cleaning liquor. 30 ml (at 65 ° C) is selected as the upper foam limit.
  • Clean 0.5 liter beer bottles are filled with 100 ml of the cleaning liquor and, after being closed, shaken vigorously five times in a cork stopper. After a short period of action (approx. 1 minute), the shaking process is repeated again for five and the detergent-containing cleaning liquor is then poured out. This is followed by rinsing four to five times in succession with 100 ml of distilled water until pH 7 is reached
  • Builders and auxiliaries 65% by weight sodium metasilicate, 20% by weight sodium hydroxide (powdered), 10% by weight sodium carbonate.
  • the surfactant components are mixed together and then the fluorinated alcohol is stirred in at 30 to 40 ° C.
  • the framework and auxiliary materials are placed in a mixing drum, where they are mixed well with the surfactant mixture.
  • Builders and auxiliaries 25% by weight of pentasodium triphosphate, 25% by weight of sodium metasilicate, 25% by weight of sodium carbonate and 15% by weight of sodium hydroxide (powdered).
  • the components of the surfactant-containing mixture are mixed and then intimately mixed with the framework and auxiliary substances that have already been mixed to form the powder.
  • Powdered dishwashing detergent
  • Builders and auxiliaries 41.5% by weight sodium metasilicate, 35% by weight pentasodium triphosphate. 20% by weight sodium carbonate and 1.5% by weight sodium dichloroisocyanurate (as disinfectant).
  • the surfactant-containing formulation which has been premixed with one another in the order of the components is incorporated into this mixture.
  • Liquid bottle cleaner
  • Builders and auxiliaries 35% by weight phosphoric acid (85% by weight), 20% by weight 2-phosphonobutane-1,2,4-tricarboxylic acid and 25% by weight deionized water.
  • Deionized water is initially introduced and phosphoric acid and 2-phosphonobutane-1,2,4-tricarboxylic acid are then stirred in. Now the premixed surfactant-containing mixture is homogenized.
  • Liquid dishwashing detergent
  • Pentasodium triphosphate is dissolved in deionized water, then phosphoric acid and finally the mixture containing surfactants are added.
