Definitions

the invention relates to mixtures of alkoxylates as foam suppressants and their use in cleaning liquors.
the system must be as low-foam or foam-free as possible, since excessive foam formation can lead to malfunctions in the operating behavior of the system, for example if the dirt accumulating in the foam layer cannot be removed sufficiently. Additional tendencies towards foam formation are caused by the impurities carried in by the items to be cleaned, especially by protein-containing residues on the items to be cleaned. In the case of bottle cleaning, this also applies to labels to be removed, through which glue residues and residues of printing inks, including the surfactant auxiliaries contained in the latter, are introduced into the cleaning liquor.
nonionic surfactants as foam-suppressing (foam-suppressing) agents in aqueous cleaning liquors.
foam-suppressing agents include foam-suppressing agents, foam-suppressing agents, and foam-suppressing agents.
foam-suppressing agents include foam-suppressing agents, foam-suppressing agents, foam-suppressing agents, and foam-suppressing agents.
foam-suppressing agents are in particular addition products of ethylene oxide and / or propylene oxide with 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 to the lowest possible foam tendency and increased cleaning action by suitable variation of the ethylene oxide and propylene oxide proportions, an excess weight of the propylene oxide favoring the former property and an excess weight of the ethylene oxide promoting the latter property.
the more recent publications WO 91/09925 and WO 92/14808 describe mixtures of alkoxylates as foam suppressors in the mechanical cleaning of hard surfaces.
the agent described in WO 91/09925 essentially consists of at least one fatty alcohol ethoxylate with 2 to 12 ethylene oxide units and at least one fatty alcohol ethoxylate propoxylate with 2 to 10 ethylene oxide units and 2 to 8 propylene oxide units in a weight ratio of 10: 1 to 1:10 and that according to WO 92/14808 from 2 fatty alcohol ethoxylate propoxylates in Weight ratio of 10:90 to 90:10, where one fatty alkyl radical has 8 to 18 carbon atoms and the other has 10 to 20 carbon atoms, with the proviso that the two fatty alkyl radicals differ by at least the average number of carbon atoms Distinguish 0.5.
These mixtures based on fatty alcohol alkoxylates alone also leave something to be desired, particularly with regard to foaming behavior.
the alkyl radicals and alkenyl radicals, R 1 and R 2 can be straight or branched, with preference being given to straight.
the alkenyl radicals preferably have 1 to 3 double bonds.
the numbers given for x, y and m plus n are statistical averages (average values), i.e. x, y, m and n can each be an integer or fractional number.
Component A) is therefore a reaction product of a fatty alcohol with first x moles of ethylene oxide and then y moles of propylene oxide, which may be of the type -CH2-CH (CH3) O- or -CH (CH3) -CH2O-, the latter being preferred .
Component B) is a fatty amine (primary amine) with the specified alkyl or alkenyl groups or preferably a reaction product of such a fatty amine with m plus n mol of ethylene oxide.
the fatty amine ethoxylates according to formula II are therefore preferred as component B).
alkyl and alkenyl radicals in formulas I and II are n-hexyl, n-heptyl, n-octyl, 2-ethylhexyl, iso-nonyl, n-decyl, iso-decyl, n-dodecyl, stearyl, n-eikosyl, Oleyl, cocoalkyl and tallow alkyl as well as alkyl or alkenyl mixtures, for example a mixture of C12-alkyl to C14-alkyl (C 12/14 ). All of the compounds according to component A) and B) are known and commercially available.
the foam-suppressing agents according to the invention are produced simply by mixing components A) and B) and, if appropriate, further expedient components and additives at a temperature of 15 to 50 ° C., preferably 20 to 30 ° C., and advantageously with stirring.
the mixtures according to the invention can be used in undiluted form, that is to say as such or, for example, for better purposes Dosage in the form of aqueous concentrates are used, optionally with the addition of an organic solvent. Of course, components A) and B) can also be added separately to the aqueous cleaning liquor.
the application concentration in the aqueous liquors is advantageously 0.05 to 10 g of the mixture according to the invention per liter of cleaning liquor, preferably 0.1 to 2 g per liter.
the application concentrations mentioned 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 impurities.
surfactant mixtures can be added to the surfactant mixtures according to the invention.
dyes include dyes, fragrances, corrosion inhibitors and disinfectants.
the known builders which are optionally also complexing agents, should also be mentioned here. These include the condensed phosphates such as tripolyphosphates and pentasodium triphosphate, the complex-forming aminopolycarboxylic acids and their salts, for example the alkali salts of nitrilotriacetic acid and ethylenediaminetetraacetic acid, and the complex-forming hydroxycarboxylic acids and polymeric carboxylic acids such as citric acid, tartaric acid and the like.
condensed phosphates such as tripolyphosphates and pentasodium triphosphate
the complex-forming aminopolycarboxylic acids and their salts for example the alkali salts of nitrilotriacetic acid and ethylenediaminetetraacetic acid
Another class of complexing builders are polyphosphonic acid 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.
the surfactant mixtures according to the invention can optionally be converted into powder form and used in this form.
the mixtures according to the invention are notable for a high foam-suppressing action. They have an extremely low tendency to foam and tendency to foam both at low and at elevated temperatures (for example in the range from 15 to 80 ° C) and also with very strong liquor movement and the presence of foam-promoting contaminants such as protein, milk, beer, lemonade, glue or other adhesives and the like.
the mixtures according to the invention have a high cleaning action and a high dirt-holding capacity. This latter property allows long service life in the system until it is refilled without impairing the cleaning effect. Their 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 and high gloss of the cleaned goods are also guaranteed.
the mixtures according to the invention are also resistant to alkali and acids and, together with them, have a long shelf life.
the surfactant mixtures according to the invention are generally suitable for suppressing foam in cleaning liquors. They are particularly suitable for alkaline fleets for the mechanical cleaning of hard surfaces, for example for fleets in household dishwashers and in commercial cleaning systems. They are particularly suitable in the case of industrial cleaning systems for hard surfaces, such as dishwashing and bottle washing systems, which work with aqueous alkaline liquors with high mechanical liquor movements in continuous operation, where the pH values can be ⁇ 10 or ⁇ 12 (highly alkaline liquors).
alkaline cleaning liquors consist essentially of 95 to 99% by weight of water and 1 to 5% by weight of sodium and / or potassium hydroxide.
the agent according to the invention is also suitable for aqueous acidic cleaning liquors which are known to consist essentially of 50 to 80% by weight of water and 20 to 50% by weight of preferably phosphoric acid or sulfuric acid.
the mixtures according to the invention have an unexpectedly low foam value. Because of their extremely low foam values and their other advantageous properties, the mixtures according to the invention are excellent additives, in particular to cleaning liquors for cleaning hard surfaces.
