Definitions

  • Aqueous cleaning agents for use in commerce and industry in particular those for cleaning metal, glass, ceramic and plastic surfaces, generally contain active ingredients which are able to counteract undesirable foam development.
  • the use of low-foam or foam-suppressing surfactant auxiliaries in particular is due in most cases to the fact that the contaminants detached from the substrates to be cleaned and accumulating in the cleaning baths act as foaming agents. This has a particular effect on high-speed cleaning machines, for example in machine bottle cleaning systems, or in applications in which the cleaning liquor is sprayed onto the surfaces to be cleaned under high pressure, for example in spray cleaning.
  • addition products of alkylene oxides to organic compounds which have — preferably several — reactive hydrogen atoms in the molecule have long been used as low-foaming or foam-suppressing additives with a surfactant effect.
  • addition products of propylene oxide onto aliphatic polyalcohols see DE-PS 12 80 45 5 and DE-PS 16 21 592
  • aliphatic polyamines see DE-PS 12 89 597 and DE-PS 16 21 -593
  • addition products of ethylene oxide and propylene oxide on aliphatic polyamines, especially ethylenediamine see DE-PS 19 44 569) proven in practice.
  • these alkylene oxide addition products also have the alkali stability which is usually required for use in commercial and industrial cleaning agents.
  • the compounds in this class are not sufficiently biodegradable to meet the applicable legal regulations (RVO on the Detergent Act).
  • the present invention is based on the task of finding foam-suppressing or foam-suppressing auxiliaries with surfactant character, the application properties of which are at least equal to those of the prior art, but which also have the required biodegradability.
  • the invention intends to provide means of the type mentioned which can also be used effectively in the low temperature range below approximately 50 ° C., which has hitherto been difficult to master even with the best relevant auxiliaries.
  • DE-OS 33 15 951 describes end group-capped polyethylene glycol ethers which can be used with advantage in the fields of application described and which are also biodegradable. In practical use, however, it has been shown that these compounds from the cited published patent develop their best activity at temperatures of about 50 ° C., while improvements in the foam behavior in the temperature range below appear particularly desirable when cleaning processes are used which are derived from the Mechanics of the process measures used particularly favor foam formation.
  • surfactant mixtures described below are already effective in the temperature range from +10 ° C., but at the same time open up the possibility of safely mastering any foam problems that may arise.
  • Wetting agent mixtures of the type according to the invention and described below can thus, for example, overcome difficulties which arise when cold starting bottle cleaning systems.
  • the surfactant mixtures according to the invention can also advantageously be used as low-foaming wetting agents for high-pressure spray cleaners which can be cold sprayed.
  • the R 1 radical in the compounds of the general formula I denotes a straight-chain or branched alkyl radical or alkenyl radical having 12 to 18 C atoms
  • the preferred R 2 radical in these compounds of the general formula I denotes the butyl radical
  • the preferred meaning for the radical R 3 is a straight-chain or branched alkyl radical having 12 to 14 carbon atoms
  • the preferred chain length for the radical R 4 in the compounds of the general formula III is 16 to 18 carbon atoms lies.
  • the residues R 1 , R 3 and R 4 are residues of corresponding longer-chain alcohols, it being a further preferred embodiment of the invention that alcohol cuts, as are obtained in practice in the synthesis of such alcohols, are particularly suitable, at least then the predominant one Proportion of the individual components actually present in these alcohol cuts correspond to the specified C number ranges.
  • Corresponding synthetic alcohols, but in particular corresponding fatty alcohols or fatty alcohol mixtures are suitable, as are obtained in a known manner from the conversion of natural fats and / or oils.
  • a particularly suitable alcohol cut for the radical R 1 in the compounds of the general formula I can be so-called "LT coconut alcohol", which shows the following carbon chain length distribution - with consistently saturated hydrocarbon radicals
  • Alcohol cuts particularly suitable for the radical R 3 in the compounds of the general formula II are characterized by the so-called “LS coconut alcohol” with the following carbon chain length distribution - likewise consistently saturated hydrocarbon radicals:
  • n is a number from 3 to 7 means.
  • Corresponding fatty alcohols and / or oxo alcohols of the stated carbon number can be used individually or as a mixture as starting material for the preparation of these polyglycol ethers of the formula I. These alcohols are reacted with ethylene oxide in a molar ratio of from 1: 3 to 1: 7, and the hydroxyl groups present in the reaction product obtained are then etherified.
  • the reaction with ethylene oxide takes place under the known alkoxylation conditions, preferably in the presence of suitable alkaline ones Catalysts.
  • the etherification of the free hydroxyl groups is preferably carried out under the known conditions of Williamson's ether synthesis with straight-chain or branched C 4 to C 8 alkyl halides, for example with n-butyl iodide, sec-butyl bromide, tert-butyl chloride, amyl chloride, tert-amyl bromide , n-hexyl chloride, n-heptyl bromide and n-octyl chloride.
  • preference is given here to the corresponding C 4 -alkyl halides. It can be expedient to use alkyl halide and alkali in a stoichiometric excess, for example from 100 to 200%, over the hydroxyl groups to be etherified.
  • the compounds of the general formulas 11 and III are likewise prepared in a manner known per se by reacting the starting alcohols or alcohol mixtures with ethylene oxide and propylene oxide (compounds of the general formula II) or with propylene oxide (compounds of the general formula III) under the known alkoxylation conditions .
  • the biodegradability of the surfactant mixtures according to the invention is over 80% BiAS decrease with BOD / COD values of greater than 60%.
  • the invention relates to the use of the low-foam or foam-suppressing surfactant mixtures described at the outset in the context of detergents which are to be used in particular for the aqueous-surfactant cleaning of hard surfaces.
  • the area of such cleaning processes is particularly affected here, in which increased foam loading is to be expected due to the mechanics used and / or the impurity to be removed, in particular here mechanical cleaning processes, such as spray cleaning or other washing or rinsing processes cleaning with high-pressure application, are suitable.
  • the wetting agent mixtures according to the invention are used in cleaning agents which are also intended for use at washing temperatures below 50 ° C., in particular in the range from approximately 10 to 50 ° C.
  • cleaning agent comprises on the one hand the ready-to-use aqueous solutions of the corresponding active ingredient components, but on the other hand also the concentrates and / or solid active ingredient mixtures intended for the preparation of the application solutions.
  • the general details of the prior art apply here in detail.
  • the ready-to-use solutions can be slightly acidic to strongly alkaline.
  • the surfactant mixtures to be used according to the invention are added to the cleaning agents in such amounts that their concentration in the ready-to-use solutions is 10 to 2500 ppm, preferably 50 to 500 ppm.
  • the substance mixtures according to the invention are compared with the substance mixtures from the comparative examples. It shows that the substance mixtures according to the invention are almost always better Antifoam behavior show than the materials from the comparative examples.
  • a product can only be used in practice if it also has a satisfactory emulsifying power.
  • the surfactants or surfactant mixtures to be determined are emulsified in 1% by weight aqueous sodium hydroxide solution at room temperature in each case in an amount of 0.1 to 1% by weight of surfactant. Only products that do not frame here are suitable for practical use.
  • test foam A 1% by weight aqueous solution of the trlethanolamine salt of tetrapropylene benzosulfonate is used as the test foam. This is metered in at intervals of one minute in amounts of 1 ml each of the liquor in circulation. The resulting total volume of foam and liquid is determined. The longer the time it takes to reach the 2,000 ml mark in the measuring cylinder due to the total volume of the liquid and foam phases, the better the foam-inhibiting effect of the surfactant material used. In Examples 1 to 6 below, the respective corresponding numerical values for this point in time are given in minutes or in ml of test foamers. At the same time, the emulsifying power is assessed as previously described. In the evaluation, a distinction is made between the 3 evaluations: good, still satisfactory, inadequate.
  • a mechanical degreasing agent for metallic materials with the following composition was produced by mechanical mixing of the components:
