Definitions

• the invention relates to mixtures of alkoxylates with foam-suppressing and disinfectant effect and their use in aqueous cleaning liquors for hard surfaces.
• Cleaning hard surfaces such as plastic or glass bottles, Porcelain, ceramic, glass or plastic dishes and other items from such materials or from metal
• Commercial and industrial Cleaning equipment is generally with an aqueous solution of Alkali metal hydroxides, preferably sodium hydroxide solution (alkaline cleaning liquor) or with aqueous acid solutions (acid cleaning liquor).
• This Cleaning systems work with high throughput and with high Fleet movements and spray intensities to ensure quick detachment and To ensure emulsification of the adhering impurities. Because of the high mechanical liquor movements, the system must be as low-foam as possible or be foam-free, since excessive foaming leads to malfunctions in the system can lead.
• Bottle cleaning also applies to the labels to be removed the glue residues and residues of printing inks including those in the latter containing surfactant aids are introduced into the cleaning liquor.
• nonionic surfactants as foam suppressants Agent in alkaline or acidic aqueous base solutions for the cleaning of hard surfaces.
• nonionic surfactants are, in particular, investment products from Ethylene oxide and / or propylene oxide over amines, fatty alcohols or alkylphenols, Polyglycol ether formals or acetals or block copolymers of ethylene and Propylene oxide.
• DE-A-25 23 588 (GB-A-1 488 108) describes polyglycol ether mixed formals in EP-B-322 781 end-capped fatty alcohol alkoxylates and in EP-A-694 606 Mixtures of a fatty alcohol ethoxylate propoxylate and a fatty amine or Fatty amine ethoxylate is described as a foam-suppressing additive to cleaning agents.
• WO-A-96/10069 in which disinfectant cleaning agents for hard surfaces are described. In detail, it is about the use a mixture of an alkyl and / or alkenyl oligoglycoside and one Fatty alcohol alkoxylate to enhance the germ reducing effect of Cleaning agents containing disinfectants for hard surfaces.
• Disinfectant the effect of which is increased by adding the mixture mentioned should be, among other things, fatty alkyl polyamines such as N, N-bis (3-aminopropyl) dodecylamine called.
• DE-A-3048642 describes surfactant mixtures for cleaning hard surfaces, in particular Bottles containing alkoxylates and quaternary ammonium salts.
• the alkyl and alkenyl radicals can be straight or branched, with preference being given to this.
• the alkenyl radicals preferably have 1 to 3 double bonds.
• the numbers given for x, y, z, a and b are statistical averages (average values), which means that these indices can each be an integer or fractional number.
• the propylene oxide units can be of the type -CH 2 -CH (CH 3 ) O- or -CH (CH 3 ) -CH 2 O-, the former being preferred.
• alkyl and alkenyl radicals 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 C 12 alkyl to C 14 alkyl (C 12/14 ).
• Components A1, A2 and A3 in the preferred mixture described can each be used alone or together, the mixing ratio being able to vary within wide limits.
• R 5 is an alkyl radical or alkenyl radical having 6 to 22 C atoms, preferably 8 to 18 C atoms
• R 6 is the radical mentioned - (CH 2 ) m -NH 2 , where m is n, that is, m and n are each an integer from 2 to 6, preferably 3.
• the particularly preferred amines of the formula IV are therefore fatty alkyl dipropylenetriamines. All components to be used according to the invention are known from the publications mentioned at the outset and are commercially available.
• the agents according to the invention are simply manufactured by Mixing the components together and, if appropriate, more appropriately Additives 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, ie as such or, for example, for better meterability in the form of aqueous Concentrates are used, optionally with the addition of an organic Solvent.
• the components described can also be added separately to the aqueous cleaning liquor.
• the Application concentration in the aqueous liquors expediently at 0.05 to 10 g of the mixture according to the invention per liter Cleaning liquor, preferably at 0.1 to 2 g per liter.
• the above Application concentrations are non-critical information since the amount in to a certain extent depending on the type of surfaces to be cleaned and on type and Scope of impurities.
• the surfactant mixtures according to the invention can be further Additives and auxiliaries for the preparation of commercial formulations added become. These are, for example, dyes, fragrances, corrosion inhibitors and Disinfectant. Also worth mentioning here are the known builders, the optionally are complexing agents at the same time. These include the condensed ones Phosphates such as tripolyphosphate and pentasodium triphosphate that are complexing acting 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.

• Another class of complexing builders are polyphosphonic acid salts, such as the alkali salts of aminophosphonic acid.
• builders can also such as silicates, for example sodium metasilicate, carbonates, bicarbonates, borates and Citrate can be added.
• the surfactant mixtures according to the invention optionally converted into powder form and are used in this form.
• the mixtures according to the invention are distinguished by a high level of disinfectant and foam suppressing effect. They are extremely low Foam tendency and tendency to foam at low and at high Temperatures (for example in the range of 15 to 80 ° C) and also at strong ones Fleet movement and the presence of foam-promoting contaminants, such as Protein, milk, beer, lemonade, glue or other adhesives and the like.
• foam-promoting contaminants such as Protein, milk, beer, lemonade, glue or other adhesives and the like.
• the equally unexpectedly high germicidal property extends to all common Microorganisms.
• the mixtures according to the invention also have a high Cleaning effect and a high dirt absorption capacity on what long Operating times allowed without affecting the cleaning effect. Your good Wetting capacity and drainage behavior enable dirt to be removed quickly and thus a high throughput of items to be cleaned.
• the cleaned good is free of Stains and streaks and shows high gloss (that means no attack on that Appearance) and no damage (that means no impairment to the Example of mechanical stability).

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). Another example is the cleaning of bottles made of glass or polyethylene terephthalate (PET) in breweries and in bottling plants for non-alcoholic beverages.
