Definitions
- Branched hydroxyalkyl polyalkylene glycol ethers and their use The present invention relates to selected branched surfactants of the hydroxyalkyl polyalkylene glycol ether type and their use in detergents or cleaners, in particular for defoaming, foam control or foam suppression of aqueous compositions containing foaming components.
- Aqueous detergents and cleaners often contain substances which lead to undesirable foaming under the conditions of use. These substances are often anionic surfactants, e.g. of the alkylbenzenesulfonate or linear alkyl sulfates type and fatty alcohol polyglycol ether sulfates, or certain nonionic surfactants such as alkyl (oligo) glycosides.
- various constituents of the contaminants to be cleaned off or substances with surface-active properties present in the application system or incorporated into the application system can form foams and / or stabilize the foaming tendency in an application and thus cause or increase the formation of foams.
- exemplary are substances and groups of substances such as e.g. Called proteins, polymers, saponified fats, wood fibers and their ingredients that form foams.
- foam-suppressing additives ie substances which prevent the formation of foams or b) defoamers are used, which are agents which can destroy existing foams.
- defoamers are used, which are agents which can destroy existing foams.
- foam regulators are known, which are substances that do not completely prevent foaming, but can limit the foam volume to a certain extent.
- Foam of the working group "Surface-active substances” from 2007 Foams are stabilized by the solid and homogeneous surfactant film on the liquid - It is therefore the task of a defoamer to destroy this film, or a foam-suppressing additive to prevent its formation.
- foam-suppressing or defoaming additives usually hydrophobic oils (eg mineral oil, paraffin oils, fatty alcohols and their esters, fatty acids and silicone oils) and their combination with finely divided hydrophobic solids are used.
- hydroxyalkyl polyalkylene glycol ethers are used here. These are known compounds which can be obtained, for example, by reacting a 1,2-epoxyalkane with an alkoxylated fatty alcohol.
- EP 0 299 360 A2 discloses such compounds and their use as foam-suppressing additives.
- EP 1 229 103 A1 discloses hydroxypolyoxylene glycol ethers and their use in cleaning agents, the description of which also describes the use of branched alcohols for the preparation, without disclosing specific compounds of this type or their properties.
- a first subject of the present invention therefore relates to hydroxyalkyl polyalkylene glycol ethers of the general formula (I)
- OH is R 1 -CH-CH 2 - (O-CHR 2 -CH 2 ) n -OR 3 (I) in which R 1 is a saturated linear alkyl radical having 6 to 18 C atoms, R 2 is a hydrogen atom or a methyl radical where the radical R 3 stands for a mono- or polysubstituted, saturated alkyl radical having 5 to 24 C atoms and the index n stands for integers or fractions of 2 to 20.
- Hydroxyalkylpolyoxylenglykolether are known in principle.
- the teaching of the present invention is based on the surprising finding that, with only variation of the polyoxyglycol-terminal radical R, the defoaming or foam-suppressing action of the hydroxyalkyl polyglycol ethers is maintained at low temperatures, whereas the purely linear derivatives disclosed concretely in the prior art are effective lose.
- the compounds of the general formula (I) are usually prepared by reacting alkoxylated branched fatty alcohols with alkyloxiranes in the presence of alkaline catalysts.
- the preparation processes are known per se and are also disclosed in EP 0 299 360 A2.
- the branched radicals R 3 in the general formula (I) thus originate from the alcohol which has been alkoxylated before the reaction with the oxirane.
- Branched alcohols are e.g. the four isopentanols, especially the

- the alcohols can also be used in the form of any mixtures with each other. It is also possible for all branched alcohols having 6 to 12 C atoms or mixtures thereof obtained by Guerbet reaction to be particularly suitable.
- 2-ethylhexyl alcohol or isooctanol is a synthetic alcohol based on propene as a raw material. Propene is reacted with CO and hydrogen to the butanal, which is then converted by aldol condensation to 2-ethyl-3-hydroxyethanol. After dehydration and catalytic hydrogenation, 2-ethylhexanol is obtained.
- Isooctanol can also be obtained by so-called oxo synthesis from olefins, carbon monoxide (CO) and hydrogen. This synthesis is also called hydroformylation. The aldehydes formed in the hydroformylation are then hydrogenated. Depending on the olefin used, various primary isoalcohols are obtained. Thus, from an isohepten mixture by hydroformylation and subsequent hydrogenation, a mixture consisting mostly of 3,3-, 3,5- and 4,5-dimethyl-l-hexanol in addition to 3- and 5-methyl-l -heptanol. Also, 6-methyl-1-heptanol is a common industrially available isooctanol.
