Definitions
- the present invention relates to rinse aids for machine dishwashing containing alkoxylated carboxylic acid esters, in particular those which have been prepared by reacting carboxylic acid esters and alkylene oxides in the presence of calcined hydrotalcites, and the use of the alkoxylated carboxylic acid esters as surfactants for the preparation of such rinse aids.
- rinse aid is used successfully today.
- the addition of rinse aid at the end of the wash program ensures that the water runs off the dishes as completely as possible, so that the different surfaces are residue-free and immaculately shiny at the end of the wash program.
- rinse aids are mixtures of nonionic surfactants, solubilizers (eg cumene sulfonate), organic acids (eg citric acid) and solvents (eg ethanol), water and, if necessary, preservatives and fragrances to influence the interfacial tension of the water in such a way that it can run off the dishes in a thin, coherent film, so that no water drops, streaks or Films remain (so-called network effect).
- the surfactants also have the task of dampening the foam which arises from food residues in the dishwasher. Since the rinse aids mostly contain acids to improve the clear dry effect, the surfactants used must also be relatively insensitive to hydrolysis against acids.
- rinse aids which contain mixed ethers as nonionic surfactants.
- a variety of different materials glass, metal, silver, plastic, porcelain are cleaned in the dishwasher. This variety of materials must be wetted as well as possible in the rinse cycle.
- Rinse aid formulations which contain only mixed ethers as the surfactant component do not meet these requirements, or do so only to a limited extent, so that the rinse aid or drying effect is unsatisfactory, particularly on plastic surfaces.
- Alkoxylated carboxylic acid esters which are prepared by homogeneous catalysis in the presence of hydroxides and reducing agents or a cocatalyst, are known from German published patent application DE-A1- 19 611 999 and the international application WO 94/13618. According to the two documents, such compounds can be used in washing, rinsing and cleaning agents.
- German published patent application DE-A-43 26 112 in turn describes low-foaming general-purpose cleaners which contain alkoxylated carboxylic acid esters in a mixture with alkyl glycosides and, if appropriate, further surfactants such as alkyl sulfates, alkyl ether sulfates and fatty alcohol polyglycol ethers.
- All-purpose cleaners of this type are intended for cleaning hard surfaces such as clinker, ceramic tiles, enamel, PVC or wooden floors.
- all-purpose cleaners always contain anionic surfactants.
- all-purpose cleaners unlike rinse aids, should have a voluminous starting foam.
- all-purpose cleaners have different surfactant concentrations used. This places different demands on all-purpose cleaners than on rinse aid.
- the object of the present invention was to provide new ecologically and toxicologically flawless rinse aids which, in terms of their application properties, give at least the same results as commercially available rinse aids and do not have the disadvantages mentioned above.
- One object of the present invention therefore relates to rinse aid for machine dishwashing containing alkoxylated carboxylic acid esters of the formula (I),
- R'CO represents an aliphatic acyl radical
- AlkO represents CH 2 CH 2 O, CHCH 3 CH 2 O and / or CH 2 CHCH 3 O
- n represents numbers from 1 to 20 and R 2 represents an aliphatic alkyl radical.
- rinse aids containing alkoxylated carboxylic acid esters and especially in a mixture with mixed ethers, hydroxymixed ethers and / or fatty alcohol polypropylene / polyethylene glycol ethers not only have high ecotoxicological compatibility, but also fully meet the requirements for a branded product with regard to the application properties.
- such rinse aids show an excellent wetting agent effect and excellent foam damping.
- Alkoxylated carboxylic acid esters which are mandatory in the rinse aid according to the invention are known from the prior art.
- such alkoxylated carboxylic acid esters are accessible by esterification of alkoxylated carboxylic acids with alcohols.
- the compounds are preferably prepared by reacting carboxylic acid esters with alkylene oxides using catalysts, in particular using calcined hydrotalcite according to the German Offenlegungsschrift DE-A-39 14 131, which provide compounds with a restricted homolog distribution.
- alkoxylated carboxylic acid esters of the general formula (I) preference is given to alkoxylated carboxylic acid esters of the general formula (I) in which R'CO is an aliphatic acyl radical having 6 to 22 carbon atoms, AlkO is a CH 2 CH 2 O-, CHCH 3 CH 2 O- and / or CH 2 -CHCH 3 O radical, n is on average from 3 to 20 and R 2 is an aliphatic alkyl radical having 1 to 22 carbon atoms.
- Preferred acyl radicals are derived from carboxylic acids having 6 to 22 carbon atoms of natural or synthetic origin, in particular from straight-chain saturated and / or unsaturated fatty acids, including technical mixtures thereof, as are obtainable by fat cleavage from animal and / or vegetable fats and oils, for example Coconut oil, palm kernel oil, palm oil, soybean oil, sunflower oil, rape oil, cottonseed oil, fish oil, beef tallow and lard.
- carboxylic acids examples include caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arenachonic acid, elaachene acidic acid, elaeachene acid acid and / or erucic acid.
- R ! CO for a straight-chain, even-numbered acyl radical with 8 to 18 carbon atoms.
- Preferred alkyl radicals R 2 are derived from primary, aliphatic monofunctional alcohols having 1 to 22 carbon atoms, which can be saturated and / or unsaturated.
- suitable monoalcohols are methanol, ethanol, propanol, butanol, pentanol and the hydrogenation products of the above-mentioned carboxylic acids with 6 to 22 carbon atoms.
- R represents a methyl radical.
- AlkO is preferably a CH 2 CH 2 O radical.
- examples of such compounds are methyl carboxylates alkoxylated with an average of 5, 7, 9 or 11 moles of ethylene oxide.
- the use of alkoxylated carboxylic esters derived from short-chain carboxylic acids, in particular those with 8 to 10 carbon atoms, is recommended. High cleaning performance is obtained with alkoxylated carboxylic acid esters which are derived from longer-chain carboxylic acids, especially those with 12 to 18 carbon atoms.
- the alkoxylated carboxylic acid esters can be contained in the rinse aids as the sole nonionic surfactant, preferably in amounts of 0.5 to 40% by weight, in particular in amounts of 5 to 35% by weight. However, the alkoxylated carboxylic acid esters are preferably present in the rinse aid in a mixture with other nonionic surfactants.
- nonionic surfactants that can be considered are mixed ethers, hydroxymixed ethers, fatty alcohol polyglycol ethers, alkylphenol polyglycol ethers, fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, alkoxylated triglycerides, alk (en) yl oligoglycosides, fatty acid (N-alkyl-vegetable) hydrolysates Wheat-based products), polyol fatty acid esters, sugar esters, sorbitan esters and polysorbates.
- the nonionic surfactants contain polyglycol ether chains, they can have a conventional, but preferably a narrow, homolog distribution.
- Preferred further nonionic surfactants are fatty alcohol polyglycol ethers, alkyl oligoglucosides, fatty acid N-alkyl glucamides, hydroxy mixed ethers and / or mixed ethers.
- nonionic surfactants used are alkyl and alkenyl oligoglycosides which follow the formula (II)
- R 3 is an alkyl and / or alkenyl radical having 4 to 22 carbon atoms
- G is a sugar radical having 5 or 6 carbon atoms
- p is a number from 1 to 10. They can be obtained according to the relevant procedures in preparative organic chemistry.
- the alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose.
- the preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides.
- the index number p in the general formula (II) indicates the degree of oligomerization (DP), ie the Division of mono- and oligoglycosides and stands for a number between 1 and 10.
- p 1 to 6
- p a for a certain alkyl oligoglycoside analytically determined arithmetic size, which usually represents a fractional number.
- Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, preference is given to those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4.
- the alkyl or alkenyl radical R can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capro alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, from hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis.
- the alkyl or alkenyl radical R 3 can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms.
- Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and their technical mixtures, as described above, which can be obtained as described above.
- Another group of preferred further nonionic surfactants are fatty acid N-alkyl polyhydroxyalkylamides which follow the formula (III)
