For such tasks there are usually employed so-called "industrial cleaners".
Such industrial cleaners are mainly used for cleaning and passivating in spray-cleaning units in the automotive industry and in the supplying industry there-of. They are suited for intermediate and final cleaning of parts which have been subjected to chipless working or machining in compound machinery-producing and -assembling plants. Virtually all relevant materials may be treated such as iron and steel, aluminum, SiluminWz, copper, brass, zinc and plastics, and the majority of organic or inorganic contaminations can be removed such as coolants/lubricants, rust-preventive oils, machining oils, drawing auxiliaries, pigments and light abraded metals. Such cleaning agents may also be applied by a conventional immersion procedure, while the application by a spray procedure is usually preferred.
The chemical base components of such industrial cleaners conventionally are surfactants and organic -, corrosion inhibitors. The latter will warrant a tempor-ary protection from corrosion during and after the treatment. Said cleaning agents, as a rule, will contain additional substances which are capable of counteracting an undesired foam development. The use of such foam-inhibiting additives in most cases is due to the fact that the contaminations removed from the substrates and being accumulated in the cleaning baths tend to act as foam-forming agents. Besides, the use of so-called anti-foam agents may be necessary because of the fact that the cleaning agents themselves contain components which under the given working conditions -i.e. especially with spraying procedures - give rise to an undesirable foam formation, for example anionic surfactants or non-ionic surfactants foaming at the respective working temperature.
From "Ullmanns Encyklopadie der technischen Chemie", 4th Edition, Volume 22 (1982), Pages 489 to 493, there has been known the use of fatty alcohcol-polyethyleneglycolethers - also called fatty alcohol ethoxylates - as the surfactant component in washing and cleaning agents. However, such addition products of ethylene oxide to fatty alcohols are not suitable for the use in spray operations, because they will much foam at application temperatures of from 15 C to 80 C. It has further been ~nown to employ fatty alcohol-ethoxylate-propoxylates as weakly foaming washing raw materials; cf., for example, the above-quoted volume of Ullmann, page 494.
In contrast thereto it was the object of the present invention to provide combinations of surfactants for cleaning hard surfaces, which combinations of sur-factants exhibit low-foaming properties over the whole D 8376 - 3 - ~ `$~- 9 temperature range that is application-technologically relevant, namely within the range of from 15 C to 80 C, and, hence, are suitable to be used in spraying operations. Moreover, said combinations of surfactants are intended to have a high cleaning power and excellent wetting properties to the substrates treated therewith;
furthermore these combinations of surfactants are to be well confectionable with additives as usual in industri-al cleaners, are to allow the cleaning solutions to run well off the treated substrate surfaces without leaving stains and spots, and are to have demulsifying proper-ties with respe¢t to non-self-emulsifying oils and fats.
Surprisingly it has been shown that mixtures of the above-mentioned non-ionic surfactants over a wide mixing range will meet the requirements described in the above wording of the object.
Thus, the present invention relates to the use oS a combination comprising non-ionic surfactants, containing (a) at least one alk~en)yl-ethoxylate having the general formula (I) R 0 (CH2CH20)n H (I) wherein R1 represents a linear or branched alkyl group or alkenyl group having from 6 to 18 carbon atoms or a cyclic alkyl group having from 5 to 6 carbon atoms and n represents a number within the range of ~rom 2 to 12, and (b) at least one alk(en)yl-ethoxylate-propoxylate having the general formula (II) R2-0-(CH2CH20)p-A-H (II) D 8 376 _ 4 _ ~ 9 wherein R2 represents a linear or branche~ alkyl group or alkenyl group having from 6 to 18 carbon atoms or a cyclic alkyl group having from 5 to 6 carbon atoms, p represents a number within the range of from 2 to 10, and A represents a group o~
the type ~(CH2~CH(CH3)~0)q~ and -(CH(C~3)-C~2-O)r~, with the sum (q ~ r) being a number within the range of from 2 to 8, while the ratio by weight of the components a : b is within the range of from 10 : 1 to 1 : 10, for cleaning hard surfaces.
As to the surfactant components (a) and (b) as usable according to the invention, the following is applicable:
In the general formula (I) as defined above of the components (a), Rl represents a linear or branched alkyl group or alkenyl group having from 6 to 18 carbon atoms.
Thus, the substituent Rl may be one of the following residues: n-hexyl, n-heptyl, n-octyl, n-nonyl, n-decyl, n-undecyl, n-dodecyl, n-tridecyl, n-tetradecyl, n-penta-decyl, n-hexadecyl, n-heptadecyl and n-octadecyl as well as the branched-chain isomers o~ said alkyl groups. In the place of the saturated alkyl groups, Rl may also represent the unsaturated alkyl residues (alkenyl groups) having a number of carbon atoms within the range mentioned above, which likewise may be linear or branch-ed. Furthermore, R1 may also stand for a cyclic alkyl group having from 5 to 6 carbon atoms, i.e. cyclopentyl or cyclohexyl. The number of the ethoxy moieties in the molecule - index n - is within the range of from 2 to 12.
D 8376 _ 5 -Within the scope of the invention, those compounds of the general formula (I~ are preferably used as the component (a), wherein Rl represents a linear al~yl or alkenyl group having from 6 to 18 carbon atoms and n represents a number within the range of from 2 to 10.
According to a particularly preferred embodiment of the present invention, the reaction product of octanol (R1 =
linear alkyl group of 8 carbon atoms) with 4 moles of ethylene oxide is employed as the surfactant component (a)-As to the preparation of the compounds having thegeneral formula (I), reference may be made, for example, to the Ullmann monograph as quoted above. Such products are also commercially available, for example under the mark designation DEHYDOL(R) (Henkel KGaA, Dusseldorf).
In the general formula (II) as defined above of the components (b), R2 represents a linear or branched alkyl group or alkenyl group having from 6 to 18 carbon atoms or a cyclic alkyl group having S to 6 carbon atoms.
Thus, the substituent R2 may be one of the residues that have already been described above in the context of the substituent Rl of the general formula (II). The number of the ethoxy moieties in the molecule - index p - is within the range of from 2 to 10. The substituent A in the general formula (II) stands for propoxy moieties, while the number of the propoxy moieties in the molecule - index (q + r) - is within the range of from 2 to 8.

The surfactant combinations are further distin-guished by a certain ratio by weight of the components a : b which generally is within the range of from lo : 1 to 1 : 10. If only these two components will be used in the manner according to the invention, then the prefer-red ratio by weight of the components a : b is within the range of from 2 : 1 to 1 : 2. If, however, the surfactant combination to be used according to the invention contains the additional component (c), then the ratio by weight of the components ~a + b) : c is within the range of from 1 : 0.1 to 1 : 4, and prefer-ably within the range of from 1 : 0.1 to 1 : 1,5.
The surfactant combinations to be used according to the invention are distinguished by a high cleaning power at temperatures within the range of from 15 C to 80 'C.
Moreover, in said temperature range they are also applicable by the spraying procedure without causing any problems, because they do not give rise to any un-desirable foam development. Further advantages are:
Very good wetting properties, very good demulsifying properties with respect to non-self-emulsifying oils and fats and the property of being well confectionable with additives as conventionally used in industrial cleaners.
The additives which are preferably employed according to the invention in addition to the surfactant combinations to be employed according to the invention may include: 3uilder substances and/or complexing ' .
D 8376 _ 9 ~ t~9 agent~, corrosion inhibitors and bases or acids. If so desired, stabilizers, solubilizers or antimicrobial agents may be employed as additives.
As the builders and/or complexing agents there may be employed, for example, alkali metal orthophosphates, polyphosphates, silicates, borates, carbonates, poly-acrylates and gluconates, as well as phosphonic acids or phosphonoalkanecarboxylic acids and/or the water-soluble alkali metal salts thereof, for example l-hydroxyethane-l,1-diphosphonic acid or 2-phosphonobutane-1,2,4-tri-carboxylic acid. Straight-chain or branched carboxylic acids and/or salts thereof are suitable as efficient corrosion inhibitors. Here, more specifically, alkanol-amine salts of straight-chain or branched monocarboxylic acids having from 3 to 11 carbon atoms are employed as corrosion inhibitors. Depending on the purpose of use, the aqueous solutions of the surfactant combinations to be used according to the invention may be acidic or alkaline; accordingly they will contain an excess of an acid or bases, for example sodium hydroxide and/or potassium hydroxide.
The preparation of the combinations of surfactants to be used according to the invention is effected by simply mixing the individual components. In the same way the production of the respective powdery or liquid cleaning agents is also effected by the addition of the surfactant combinations to be used according to the invention with the other additives and optionally with water. Within the scope of the invention, such cleaning agents contain from 1 to 70 % by weight, and preferably from 2 to 20 % by weight, of the surfactant combinations to be employed according to the invention.
, D 8376 - 10 - 2~ 5 ~ r~,g Within the scope of the invention, the surfactant combinations to be employed according to the in~ention are preferably used in the for~ of water-diluted appli-cation solutions. Said application solutions preferably contain the surfactant combinations to be used according to the invention in concentrations of from 0.0001 to 1.5% by weight, and especially of from 0.0005 to 0.5% by weight. Such ready-to-use application solutions which within the scope of the invention may be employed by a spraying procedure for cleaning hard surfaces may likewise be from strongly acidic to strongly al~alin~
