Definitions

the invention relates to low-foaming and biodegradable rinse aids for machine dishwashing with good wetting and draining effects on hard surfaces.
the rinse aid must be as low-foaming as possible. Since the usual anionic surfactants, such as higher molecular weight alkyl sulfates or alkyl or alkylarylsulfonates, are known to have a strong tendency to foam and are therefore not suitable for this use, Practice non-ionic surfactants based on ethylene oxide adducts on fatty alcohols, alkylphenols or polypropylene glycols of higher molecular weights.
nonionic alkoxylation products which are sparingly water-soluble at rinse temperatures are suitable, such as, for example, ethylene oxide adducts with higher alcohols, alkylphenols or amines with a low degree of ethoxylation or corresponding adducts of ethyl oxide and propylene oxide or propylene oxide and ethylene oxide.
ethylene oxide adducts with higher alcohols, alkylphenols or amines with a low degree of ethoxylation or corresponding adducts of ethyl oxide and propylene oxide or propylene oxide and ethylene oxide have no wetting effect at application temperatures and therefore represent a burden on the rinse aid.
the adducts mentioned show an excellent drainage and clear drying effect, but they can no longer be used because of the biodegradability which is no longer regarded as sufficient .
the invention therefore relates to the use of end-capped alkyl polyethylene glycol ethers of the following general formula in which R 'is a straight-chain or branched alkyl or alkenyl radical with 8 to 18 carbon atoms, R 2 is an alkyl radical with 4 to 3 carbon atoms and n is a number from 7 to 16, as a nonionic low-foaming surfactant in rinse aid for machine dishwashing in the home and Business.
polyglycol ethers of the formula described above are used in which n is a number from 8 to 14, preferably 9 to 12 and R 2 is an n-butyl radical.
the alkyl polyethylene glycol ethers used according to the invention are used in the rinse aid in a concentration of 5 to 80, preferably 15 to 50% by weight and preferably in aqueous solution.
these ethers only develop their low foam level above 45 ° C, so that their sole use in rinse aid would make little sense, they can, however, be excellently mixed with the lower ethoxylated ethers to be used according to the invention and additionally impart a high level of rinse aid with good low foam content Wetting ability, which is particularly important for plastic dishes that are difficult to wet by nature.
the mixing ratio of higher to lower ethoxylated ethers should be chosen so that the cloud point of the mixture is not higher than 45 ° C.
the invention therefore also relates in particular to the use of end-capped alkyl polyethylene glycol ethers of the formula in which R is a straight-chain or branched alkyl or alkenyl radical with 8 to 18 carbon atoms, R 2 is an alkyl radical with 4 to 8 carbon atoms and n is a number from 7 to 16, in a mixture with end-capped alkyl polyethylene glycol ethers of the formula in which R 1 and R 2 have the meaning given for formula I and m is a number from 17 to 23, the cloud point of the mixture of ethers of the formulas I and II being not higher than 45 ° C., as a nonionic low-foaming surfactant mixture in rinse aid for automatic dishwashing in the home and business.
fatty alcohols n-octanol, n-decanol, n-dodecanol, n-tetradecanol, n-hexadecanol, n-octadecanol, n-octadecen-9,10-ol (oleyl alcohol ) and oxo alcohols of the stated carbon number can be used individually or in a mixture.
the fatty alcohols described above are advantageously reacted with ethylene oxide in a molar ratio of 1: 7 to 1:16 or in a molar ratio of 1:17 to 1:23, and the ether 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 catalysts.
the etherification of the free Hydroxyl groups are preferably carried out under the known conditions of Williamson's ether synthesis with straight-chain or branched C 4 -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. It may be expedient to use a stoichiometric excess of alkyl halide and alkali, for example from 100 to 200%, based on the number of hydroxyl groups to be etherified.
the invention therefore also relates to a process for the production of low-foaming rinse aids for machine dishwashing in household and commercial use, which is characterized in that alkanols or alkenols of the formula R 1- OH, in which R 1 is a straight-chain or branched alkyl or Alkenyl radical having 8 to 18 carbon atoms means in a molar ratio of 1: 7 to 1:16, preferably 1: 8 to 1:14 and in particular 1: 9 to 1:12 or in a molar ratio 1:17 to 1:23, preferably 1 18 to 1:20 in the presence of alkaline catalysts ethoxylated with ethylene oxide, then etherifying the free hydroxyl groups with straight-chain or branched C 4 -C 8 -alkyl halides, preferably in an excess of 100 to 200%, based on the number of hydroxyl groups, the respective reaction products mixes with one another without the cloud point of the mixture exceeding 45 ° C.
the alkyl polyethylene glycol ether mixture used according to the invention is used in the rinse aids in a concentration of 5 to 80, preferably 15 to 50% by weight and preferably in aqueous solution.
solubilizing substances such as, for example, mono- or polyhydric alkanols (for example ethanol, propanol, isopropanol, ethylene glycol, propylene glycol).
Hydrotropic substances such as the alkali metal salts of low molecular weight alkylbenzenesulfonic acids, sodium cumene sulfonate, sodium xylene sulfonate or sodium toluenesulfonate, are also effective.
the amounts of the solvents and / or the hydrotropes can be between 0 and 40% by weight, based on the total rinse aid.
0 to 40 preferably 10 to 35% by weight, based on the total rinse aid, of complexing agents, such as, for example, citric acid, tartaric acid, glycolic acid and / or a commercial technical mixture of succinic acid, glutaric acid and adipic acid (Sokalan DCS (R) from BASF) can be used.
complexing agents such as, for example, citric acid, tartaric acid, glycolic acid and / or a commercial technical mixture of succinic acid, glutaric acid and adipic acid (Sokalan DCS (R) from BASF
Binc AM 2-phosphonobutane-1,2,4-tricarboxylic acid
concentrations can also be lower and can be 0 to 10% by weight, preferably 2 to 7% by weight, based on the total rinse aid.
customary colorants, fragrances and preservatives can be added in the customary manner for use in rinse aids.
Alkalinity and temperature correspond to the conditions in a commercial dishwasher.
Degradability was also measured according to the GF test method specified in the Chemicals Act for "ready biodegradability" according to the GFIBSB test regulation (C0D / Chemical Oxygen Demand).
a highly effective rinse aid for dishwashers had the following composition (wt. 5):
the solutions were clear between -2 ° and + 50 ° C and stable in storage. In a commercial dishwasher, there was no disruptive foam at the existing detergent liquor temperature of 60 ° C. The clear dry effect at a dosage of 0.2 to 1.0 g / l was excellent.
the following rinse aid formulation resulted in a household dishwasher: when used in a rinse cycle with a liquor at 65 ° C at a dosage of 0.1 to 0.8 g / l, especially on glasses, a good clear drying effect:
a rinse aid with a mixture of two of the surfactants used according to the invention was used in a commercial 1-tank dishwasher.
Suitable rinse aids can also be packaged in a mixture with small amounts of other low-foaming nonionic surfactants.
a highly effective rinse aid for commercial dishwashers had the following composition (% by weight):
the cloud point of the ether mixture was 38 ° C.
the clear dry effect at a dosage of 0.1 to 1.5 g / l was excellent, especially on plastic dishes that were difficult to wet.
the rinse aid With a dosage of the rinse aid of 0.1 to 1.5 g / l, a good clear drying effect, in particular on plastic dishes, was found both when used in a commercial and in a household dishwasher.
the rinse aid is low-foaming above 44 ° C and also shows little foam when carried into the cleaning cycle of commercial dishwashers with low foam load at temperatures around 60 ° C.
the clear dry effect of two of the surfactants used according to the invention was compared to the less readily degradable surfactant sec-C 11-15 alcohol + 8 EO + 5 PO (according to DE-PS 21 06 819) with a similar cloud point.
the tests were carried out in a household dishwasher (softened water; 300 mg salt load) with one cleaning and one rinse cycle, with grades from 1 (very poor) to 10 (optimal rinse; highest possible grade).
the dosage of the surfactants in the rinse aid was 0.02 to 0.1 g / l.
Drinking glasses served as items to be washed, as they are most sensitive to stains, streaks and streaks. That grade 10 was not achieved here is due to the very critical grading and the fact that the water used was softened but not desalinated. Note 10 is only possible if demineralized water is used.
