Definitions
- the present invention relates to a mixture of at least two alkoxylated alcohols of the general formula I.
- x denotes a number between 1 and 12 and y denotes a number between 1 and 15,
- an alkoxylated alcohol carries a straight-chain or branched C ⁇ -Ci ⁇ -alkyl group as the radical R and another carries a straight-chain or branched C ⁇ o-C2o-alkyl group as the radical R, but the two radicals R are in the average number of carbon atoms must distinguish at least 0.5, and both alkoxylated alcohols are present in a ratio of 10:90 to 90:10.
- the invention also relates to the use of this mixture as a foam-suppressing surfactant additive in cleaning agents for machine-operated cleaning processes. Furthermore, the invention relates to detergents containing such mixtures of alkoxylated alcohols I.
- wetting agents such as ethylene and / or propylene oxide adducts with alcohols, phenols or amines may be mentioned, for example.
- EP-A 161 537 (2) relates to the use of non-ionic surfactants which are end group-capped with methyl, ethyl or allyl radicals and which can be obtained by stepwise alkoxylation of C 8 -C 22 -alkanols with at least two different alkylene oxides, as low-foam, foam-suppressing and Biodegradable surfactants in industrial cleaning processes.
- EP-B 019 173 (3) relates to the use of Cg-C s-alkanols first reacted with propylene oxide and then with ethylene oxide as low-foaming and biodegradable surfactant additives in dishwashing detergents for dishwashers.
- surfactants of the type mentioned and mixtures thereof also prove to be in need of improvement when used in cleaning agents for mechanically running cleaning processes, in particular the foam-damping behavior and the dispersibility in water are not yet optimal.
- the present invention was therefore based on the object of remedying the deficiencies described in the prior art. We have found that this object is achieved by the mixture of at least two alkoxylated alcohols I defined at the outset and its use as a foam-suppressing surfactant additive in cleaning agents for machine-operated cleaning processes.
- Examples of straight-chain or branched C ⁇ -Ci ⁇ - or C ⁇ o-C2 ⁇ ⁇ alkyl radicals for R are: n-octyl, 2-ethylhexyl, n-nonyl, iso-nonyl, n-decyl, iso-decyl, n-undecyl, n -Dodecyl, n-tridecyl, iso-tridecyl, n-tetradecyl, n-pentadecyl, n-hexadecyl, n-heptadecyl, n-octadecyl and n-eicosyl.
- the radicals R are preferably straight-chain or only branched to a small extent, i.e. they contain a maximum of 3 methyl or ethyl side chains.
- R is a residue of naturally occurring fatty alcohols or preferably of synthetically produced oxo or Ziegler alcohols.
- alcohols which can be used well after the oxo synthesis are Cg / Cu, C 12 C I-C13 C15 and Cis / Ci ⁇ -alkanol mixtures.
- Examples of readily usable alcohols produced by the Ziegler synthesis are ⁇ / C ⁇ o, C ⁇ o / C! 2-, C12 C1 -, C 12 / C ⁇ 6 - and C ⁇ 6 / C 2 o-alkanol mixtures.
- alkanols used in the synthesis of the compounds I generally represent statistical homologues and isomer mixtures, it is expedient to speak of an average number of carbon atoms. This average value usually represents the maximum frequency.
- Alkanols prepared in a manner known per se. These methods are known to the person skilled in the art and require no further explanation.
- the degree of ethoxylation x is 1 to 12, preferably 2 to 5, in particular 3 to 4; the degree of propoxylation is 1 to 15, preferably 2 to 6, in particular 4 to 6.
- the degrees of alkoxylation x and y generally also represent average values.
- a mixture of at least two, preferably two or three, in particular two, alkoxylated alcohols I is used, two radicals R having to differ by at least 0.5 in the average number of carbon atoms, and the corresponding two alkoxylated alcohols in the ratio of 10:90 to 90:10, preferably 25:75 to 75:25.
- a difference in the average number of C atoms of the two radicals R of at least 1, in particular a difference of 1 to 2, is particularly favorable.
- Mechanical cleaning processes are mainly found in the metal industry, in the food industry, e.g. the beverage, canning, sugar industry or milk, meat and fat processing industry, in the catering trade and also in the household.
- metal objects often have to be removed after their manufacture or processing soiling and residues, which originate from drawing and rolling greases or organic corrosion protection agents. All surfaces of containers and tools that come into contact with food during production and processing, as well as during transport, must be cleaned from food residues and other contaminants at certain intervals.
- a typical example of an industrially carried out machine cleaning process from the beverage industry is the washing of used bottles which, for example, contained beer, milk, soft drinks or mineral water.
- a rinse aid commonly used here contains nonionic surfactants, hydrotropes (solubilizers) such as isopropanol, ethanol and / or cumene sulfonate, water and, if appropriate, organic or inorganic acids and auxiliaries such as colorants and preservatives.
- the present invention also relates to a process for the preparation of cleaning agents for machine-running cleaning processes, in particular rinse aids for machine dishwashing, which is characterized in that a mixture of at least two alkoxylated alcohols I is added to these agents as a foam-suppressing surfactant additive.
- the present invention furthermore relates to cleaning agents for machine-operated cleaning processes which contain a mixture of at least two alkoxylated alcohols I as a foam-suppressing surfactant additive in an amount of 0.1 to 40% by weight, preferably 0.5 to 20% by weight. , based on the total amount of the formulation.
- the present invention furthermore relates to rinse aids for machine dishwashing, which comprise a mixture of at least two alkoxylated alcohols I as foam-suppressing surfactant additive in an amount of 0.5 to 30% by weight, preferably 1 to 15% by weight. %, based on the total amount of the formulation.
- rinse aid formulations for machine dishwashing in the household were produced.
- the following table shows the compositions of these formulations.
- the cloud point was determined in accordance with DIN 53 917. From practical studies, it is known that falling cloud points, equivalent to an increase in hydrophobicity, result in improvements in the foaming behavior, but on the other hand reduce the dispersibility, which leads to an uneven distribution of the rinse aid in the washing liquor and thus to a deterioration ⁇ the behavior of the drainage (spots, stripes and streaks) leads. At cloud points ⁇ 40 ° C., instability, ie phase separation, of the rinse aid formulation is also observed.
- the foam damping behavior is checked in the dishwasher by the so-called "egg test". In this case, the number of revolutions of a spray arm is determined by magnetic induction measurement in a commercially available domestic dishwasher with the aid of a counter.
- Foam formation which occurs particularly in the presence of proteins (protein), reduces the number of revolutions of the spray arm. Because of the reduced recoil force, the number of revolutions therefore represents a measure of the suitability of surfactants in cleaning devices with high mechanics.
- the test time is 12 minutes, the average number of revolutions per minute being calculated from the total number of revolutions.
- the washing process is started at room temperature, after about 10 minutes the temperature of the rinsing water is 60 ° C.
- the rinse aid formulation is injected into a glass tube through which tap water at 90 ° C. flows through a membrane pump. At the end of the glass tube, the dispersion produced in this way is sprayed through a second nozzle into a beaker. With a running time of about 3.5 minutes, about 30 ml of rinse aid formulation are metered into a water stream of 2 liters of water at 90 ° C. The dispersion is visually assessed and graded in the glass tube and beaker, based on the following grading scheme:
- Grade 3 moderate dispersion in the glass tube, moderately dispersed in the beaker (fine droplets of approx. 1 mm)
- Grade 4 good dispersion in the tube, fine dispersion in a beaker (droplets ⁇ 0.5 mm)
- compositions Composition, cloud point, dishwasher speed and dispersibility of rinse aid formulations
- Surfactant A C ⁇ 3 / Ci5-oxo alcohol + 11 mol ethylene oxide + 2 mol butylene oxide according to (1)
- Surfactant B Cg / Cn-oxo alcohol + 7 mol ethylene oxide + 1 mol butylene oxide + methyl end group lock according to (2)
- Surfactant C Ci 3 / C15 oxo alcohol + 4 mol propylene oxide + 2 mol ethylene oxide according to (3)
- Example 5 shows that when using the surfactant additives to be used according to the invention (Examples 5 and 6), rinse aid formulations are obtained which combine excellent foam-damping behavior with excellent dispersibility, despite a sometimes very low cloud point (Example 5). Frequently, the lowering of the cloud point by adding a hydrophobic surfactant leads to an improvement in foam damping, but at the same time to a loss of the dispersing properties. The cloud point is usually raised again by the addition of solubilizers and thus the dispersibility is improved.
- Example 5 shows that by adding the specified mixtures of compounds I to solubilizers to raise the cloud point completely or at least partially.
- Comparative Examples 2, 3, 4 and 7 show how the addition of or mixture of known agents from the prior art improves foam damping somewhat, but the dispersibility is impaired by lowering the cloud point.
