Description

The present invention relates to the use of alkoxylated polyamines in combination with low alkoxylated nonionic surfactants to enhance the primary detergency of laundry detergents or cleaners when washing textiles or cleaning hard surfaces against especially proteinaceous soils, and detergents and cleaners containing such a combination.

Detergents contain in addition to the indispensable for the washing process ingredients such as surfactants and builder materials usually further ingredients that can be summarized under the term washing aids and include as different drug groups such as foam regulators, grayness inhibitors, bleach, bleach activators and dye transfer inhibitors. Such excipients also include substances whose presence enhances the detergency of surfactants, without them usually having to have a surfactant behavior itself. The same applies mutatis mutandis to cleaners for hard surfaces. Such substances are often referred to as Waschkraftverstärker.

Alkoxylated polyamines and their use in detergents and cleaners are known, for example, from international patent applications WO 95/32272 A1 and WO 2006/108857 A1 known. From the international patent application WO 2006/108856 A1 For example, amphiphilic water-soluble alkoxylated polyamines having an inner polyoxyethylene block and an outer polyoxypropylene block are known

Surprisingly, it has been found that alkoxylated polyamines then have particularly good primary washing power enhancing properties when combined with certain nonionic surfactants.

The invention therefore provides the use of a combination of polyalkoxylated polyamines which are obtainable by reacting polyamines with alkylene oxide, in particular ethylene oxide and / or propylene oxide, with alkoxylated C ₈ -C ₁₈ -alcohols having an average degree of alkoxylation in the range from 1 to 5, in particular from 2 to 4, in detergents or cleaners to enhance the primary washing or cleaning power when washing textiles or when cleaning hard surfaces against soiling. Preferably, the weight ratio of polyalkoxylated polyamine to alkoxylated C ₈ -C ₁₈ -alcohol having an average degree of alkoxylation of 1 to 5 is in the range of 1: 3 to 3: 1, in particular 1: 2 to 2: 1.

Another object of the invention is the use of polyalkoxylated polyamines which are obtainable by reacting polyamines with alkylene oxide, in particular ethylene oxide and / or propylene oxide, to enhance the primary washing or cleaning power of detergents or cleaners containing alkoxylated C ₈ -C ₁₈ - Alcohol with average degree of alkoxylation in the range of 1 to 5, in particular from 2 to 4, when washing textiles or when cleaning hard surfaces.

It should be mentioned as a particular advantage of the invention that the primary washing power-boosting effect is particularly pronounced if the aim is to remove protein-containing soiling.

An embodiment of the invention is therefore the corresponding use for the removal of proteinaceous soils, such as blood, egg, milk, or stains proteinaceous preparations, such as chocolate, latte, pudding.

Another object of the invention is a method for removing stains, especially proteinaceous stains or stains proteinaceous preparations, textiles or hard surfaces, in which a detergent or cleaning agent and a combination of polyalkoxylated polyamine and low alkoxylated alcohol are used. This method can be carried out manually or mechanically, for example by means of a household washing machine or dishwasher. It is possible to apply the particular liquid agent and drug combination simultaneously or sequentially. The simultaneous application can be particularly advantageous by the use of an agent containing the drug combination perform. The concentration of said polyalkoxylated polyamine in the especially aqueous washing or cleaning liquor is preferably 1 mg / l to 500 mg / l, in particular 5 mg / l to 200 mg / l; the concentration of said low alkoxylated alcohol in the particular aqueous washing or cleaning liquor is preferably 1 mg / l to 500 mg / l, in particular 5 mg / l to 200 mg / l.

In the context of the present invention and its individual aspects, the polyalkoxylated polyamine is a polymer having an N-atom-containing backbone which carries polyalkoxy groups on the N atoms. The polyamine has primary amino functions at the ends and preferably both secondary and tertiary amino functions inside; if appropriate, it may also have only secondary amino functions on the inside, so that the result is not a branched-chain but a linear polyamine. The ratio of primary to secondary amino groups in the polyamine is preferably in the range from 1: 0.5 to 1: 1.5, in particular in the range from 1: 0.7 to 1: 1. The ratio of primary to tertiary amino groups in the polyamine is preferably in the range from 1: 0.2 to 1: 1, in particular in the range from 1: 0.5 to 1: 0.8. Preferably, the polyamine has an average molecular weight in the range of 500 g / mol to 50,000 g / mol, in particular from 550 g / mol to 5000 g / mol. If applicable here and later for others polymeric ingredients indicated average molecular weights are weight average molecular weights M _w , which can be determined in principle by means of gel permeation chromatography using an RI detector, the measurement is advantageously carried out against an external standard. The N atoms in the polyamine are separated from one another by alkylene, alkenylene, arylene and / or alkylarylene groups, preferably by alkylene groups having 2 to 12 C atoms, in particular 2 to 6 C atoms, where not all groups have the same C Must have atomic number. Particularly preferred are ethylene groups, 1,2-propylene groups, 1,3-propylene groups, and mixtures thereof. The primary amino functions in the polyamine can carry 1 or 2 polyalkoxy groups and the secondary amino functions 1 polyalkoxy group, although not every amino function must be alkoxy group substituted.

The alkoxy groups in the polyalkoxylated polyamine are alkoxy groups, preferably propoxy and / or ethoxy groups, which are directly attached to N atoms are bonded, and optionally to alkoxy groups, preferably propoxy and / or ethoxy groups which are bonded to alkoxy. The polyalkoxylated polyamines are obtainable by reacting polyamines with alkylene oxide, preferably propylene oxide and / or ethylene oxide, together with a plurality of alkylene oxides, preferably propylene oxide and ethylene oxide, together or first one and then the other, preferably propylene oxide and then ethylene oxide or first ethylene oxide and then propylene oxide, can be used. If desired, the terminal OH function of at least some of the polyalkoxy substituents can be replaced by an alkyl ether function having 1 to 10, in particular 1 to 3, C atoms.

Alkoxylated C ₈ -C ₁₈ -alcohols in the context of the present invention and their individual aspects are obtainable by reacting corresponding alcohols with alkylene oxide, preference being given to primary linear or branched-chain alcohols. Accordingly, the alkoxylates of primary alcohols having linear, in particular decyl, dodecyl, tridecyl, tetradecyl, hexadecyl or octadecyl radicals and mixtures thereof are useful. In preferred embodiments of the invention, the alcohol has a maximum of 16 C atoms, in particular 12 to 14 C atoms. The degree of alkoxylation, that is the average number of alkoxy groups per alcohol function, of the lower alkoxylated alcohol can be integer or fractional and preferably in the range from 2 to 4, in particular from 2 to 3.5. Preferred alkoxy groups are ethoxy, propoxy and butoxy groups, especially ethoxy groups and mixtures of ethoxy and propoxy groups.

Detergents or cleaning agents containing the active ingredients to be used in combination according to the invention or used together with them or used in the process according to the invention may contain all other usual constituents of such agents which do not undesirably interact with an active ingredient essential to the invention. Preferably, the washing or cleaning agent contains an active substance combination as defined above in amounts of from 0.3% by weight to 20% by weight, in particular from 0.7% by weight to 6.5% by weight.

Surprisingly, it has been found that such active ingredients positively influence the action of certain other detergent ingredients and, conversely, that the action of the active ingredient combination is additionally enhanced by certain other ingredients. These effects occur in particular with synthetic anionic surfactants of the sulfate and sulfonate type, which is why the use of at least this and optionally one or more of the said further ingredients together with the active ingredient combination to be used according to the invention is preferred.

An agent which contains or is used together with an active ingredient combination to be used according to the invention or is used in the process according to the invention preferably contains synthetic anionic surfactants of the sulphate or sulphonate type, in amounts of preferably not more than 20% by weight, in particular of 0.1 wt .-% to 18 wt .-%, each based on the total agent. Suitable synthetic anionic surfactants which are particularly suitable for use in such compositions are the alkyl and / or alkenyl sulfates having 8 to 22 C atoms which carry an alkali, ammonium or alkyl or hydroxyalkyl-substituted ammonium ion as counter cation. Preference is given to the derivatives of the fatty alcohols having in particular 12 to 18 carbon atoms and their branched-chain analogs, the so-called oxo alcohols. The alkyl and alkenyl sulfates can be prepared in a known manner by reaction of the corresponding alcohol component with a conventional sulfating reagent, in particular sulfur trioxide or chlorosulfonic acid, and subsequent neutralization with alkali metal, ammonium or alkyl or hydroxyalkyl-substituted ammonium bases. The sulfate-type surfactants which can be used with particular preference include the abovementioned sulfated alkoxylation products of the alcohols mentioned, so-called ether sulfates. Such ether sulfates preferably contain from 2 to 30, in particular from 4 to 10, ethylene glycol groups per molecule.

Preferred sulfosuccinates contain C ₈ to C ₁₈ fatty alcohol residues or mixtures of these. Particularly preferred sulfosuccinates contain an ethoxylated fatty alcohol radical, which in itself is a nonionic surfactant.
