Definitions

• the invention relates to a liquid cleaning concentrate with a nonionic surfactant and a combination of three solubilizers for strongly alkaline cleaning formulations.
• nonionic surfactants cannot easily be incorporated into aqueous, strongly alkaline formulations. They easily form a separate phase from the aqueous phase and therefore a solubilizer is required.
• DE-OS 27 54 831 discloses the use of ene adducts of maleic anhydride with unsaturated fatty acids having 12 to 24 carbon atoms or their triglycerides as solubilizers for nonionic surfactants in a ratio of 1: 1 to 10: 1.
• the use of monocarboxylic acids having 6 to 11 carbon atoms, such as ethylhexanoic or isononanoic acid, as solubilizers for nonionic surfactants in strongly alkaline aqueous solutions in a ratio of 1: 1 to 10: 1 is described in DE-OS 27 54 359.
• the disadvantage of this is that only limited amounts of nonionic surfactant and alkali can be incorporated with these solubilizers. For example, with 3% by weight of nonionic surfactant, at most about 5% by weight of sodium hydroxide, with 5% by weight at most 10% by weight of sodium hydroxide.
• an alkaline detergent concentrate for bottle washing is an aqueous concentrate containing 10 to 35% by weight of alkali metal hydroxide and 10 to 50% by weight of a mixture of a polyoxypropylene-polyoxyethylene condensate, an etherified ethoxylated alcohol and one Alkyl glucoside.
• the object of the invention is to be able to provide a highly fat-emulsifying, low-foaming and biodegradable preparation, in particular for the commercial sector, such as dairies and breweries, which, when used in the presence of strong alkali, i.e. up to 50% by weight, clear solutions result.
• the solution to the problem consists in a concentrated mixture in the form of an aqueous solution of a nonionic surfactant and a combination of three solubilizers, which can be mixed with water and strong alkali in practice without difficulty.
• the particular advantage of the mixture is that it is a clear solution that can be mixed with strong alkali without phase separation.
• strong foam damping or low foam is also achieved with regard to the alkyl glucoside content.
• the concentrate according to the invention is mixed with water and alkali metal hydroxide to give a cleaning formulation which contains 5 to 30, preferably 5 to 20% by weight of the concentrate according to the invention, 10 to 50, preferably 20 to 50% by weight of sodium or potassium hydroxide and the rest Contains 100% by weight of water.
• a cleaning formulation which contains 5 to 30, preferably 5 to 20% by weight of the concentrate according to the invention, 10 to 50, preferably 20 to 50% by weight of sodium or potassium hydroxide and the rest Contains 100% by weight of water.
• such an alkaline cleaning formulation expediently uses 0.1 to 10 g per liter of water.
• C 12 / C 14 and C 13 / C 15 alcohols are particularly preferred.
• the fatty alcohols mentioned are alkoxylated with 1 to 12 ethylene oxide units (EO), preferably 2 to 10 EO, and additionally with 1 to 6 propylene oxide (PO) or 1 to 3 butylene oxide units (BO).
• EO ethylene oxide units
• PO propylene oxide
• BO butylene oxide units
• the alkoxide units can be present in statistical distribution or in blocks.
• alkoxide blocks are preferably fatty alcohols which have first been reacted with the entire EO and then with the entire PO or BO. These alkoxide blocks can also be in the reverse order.
• the terminal OH groups can be etherified.
• the preferred alkyl radicals are methyl, ethyl or isopropyl.
• Examples include the methyl ethers of C 13 / C 15 fatty alcohol with 6 EO and 3 PO or 8 EO and 5 PO in block form.
• the preferred amount of nonionic surfactant is 15 to 20% by weight.
• alkyl mono- and alkyl polyglucosides an alkyl radical with 10 C atoms, i.e. n-decyl.
• the alkyl glucoside to be emphasized is the n-decyl monoglucoside, which has a certain content of polyglucosides with up to 4 glucose units. It is the commercially available n-decyl glucoside.
• the preferred amount of alkyl mono- and / or alkyl polyglucoside is 40 to 45% by weight.
• the alkyl glucoside which also has surfactant properties, is used as a solubilizer combined with a maleic anhydride adduct on an unsaturated fatty acid having 12 to 24, preferably 14 to 18, carbon atoms in a molar ratio of 0.8 to 1.2, as described in DE OS 27 54 831 can be obtained, used together with 2-ethylhexanoic acid or isononanoic acid (3,5,5-trimethylhexanoic acid).
• unsaturated fatty acids as an adduct to maleic anhydride examples include oleic acid (cis-A-9,10-octadecenoic acid), elaidic acid, lauroleic acid and myristoleic acid.
• the preferred adduct is the reaction product of maleic anhydride and oleic acid in a molar ratio of 0.8 to 1.2, in particular 1: 1.
• the preferred amount of maleic anhydride adduct to an unsaturated fatty acid in the mixture according to the invention is 1 to 5% by weight.
• the preferred amount of 2-ethylhexanoic acid or isononanoic acid is 10 to 15% by weight.
• the mixture is prepared by dissolving the total amount of water in the alkyl glucoside and adding the solid or liquid remaining constituents in succession while stirring. A clear solution is obtained.
• Number of revolutions of the spray arm per minute in a Miele G 19 are mean values over a period of 11 minutes and show the foaming process, which is increased by additional protein contamination (10 g mixed chicken protein per 10 l water).
