Abstract

Washing and cleaning agents are described, which contain a specific amidine compound and/or a specific amidinium bicarbonate. These washing or cleaning agents enable an improved removal of contaminants in the case of pigment contamination and fat and oil soiling. The use of special amidine compounds and amidinium bicarbonate in a washing solvent is also described, which enables carbon dioxide from the ambient air to bind in the washing solvent.

Description

Detergents or cleaners with amidine compounds and / or amidinium bicarbonates

The present invention relates to detergents containing a particular amidine compound and / or a particular amidinium bicarbonate. It further relates to a textile washing process using such detergents or cleaning agents. It also relates to the use of such laundry detergents or cleaners in connection with manual or automatic textile laundering, in particular in connection with the improvement of soil release on pigment soiling and on grease and oil soiling. Furthermore, it relates to the use of the specific amidine compound and / or the specific Amidiniumbicarbonates in a wash liquor to receive carbon dioxide from the ambient air in the wash liquor and to bind in this.

At least since 1907, when Persil® was the first self-acting laundry detergent, laundry detergents and home care products have been among those consumer goods that are particularly useful in making people's lives easier, better and more beautiful. Despite all the progress achieved so far, it is the aim of the manufacturers of detergents or cleaners to improve the quality of their products on and on.

A very specific challenge in this general background is the provision of detergents with improved cleaning performance based on motor oil based soiling. With significant soiling of this kind, e.g. especially employees of car repair shops faced. Engine oil (or motor oil) is the collective name for such mineral oils, including synthetic oils with or without mineral oil additives, which are suitable as lubricants for engines.

The object of the present invention was to cope with the aforementioned specific challenge. Surprisingly, it has now been found that it is precisely those detergents or cleaners which contain certain amidine compounds and / or amidinium bicarbonates which are capable of accomplishing this task.

The object of the present invention is therefore a washing or cleaning agent containing an amidine compound of the formula (1), ₎ and / or an amidinium bicarbonate of the formula (2),

where the radicals R ¹ , R ² , R ³ , R ⁴ independently of one another are C 1 -C ₂₅ -hydrocarbon radicals or H. The saturated or unsaturated, optionally substituted C ₁ -C _2S hydrocarbon radicals may be straight-chain, cyclic or branched. (This basic statement about the hydrocarbon radicals in connection with the amidine compounds of the formula (1) and the amidinium bicarbonates of the formula (2) also in the following, but is not mentioned there to avoid repetitions).

It is preferred that at least one of R ¹ , R ² , R ³ or R ⁴ , in particular the radical R ² , is a C ₆ -C ₈ -hydrocarbon radical, preferably C ₈ -C ₈ -hydrocarbon radical, the other radicals R ¹ , R ² , R ³ or R ⁴ , which are not C ₆ -C ₈ -hydrocarbon radicals, independently of one another are preferably C 1 -C ₄ -hydrocarbon radicals or H. If in the amidine compound (1) and / or in the Amidiniumbicarbonat (2), the radical R ² stands for a C-ι-C ₁₈ hydrocarbon radical, in particular R ² is a saturated, straight-chain C ₈ -C ₁₈ hydrocarbon radical, and Radicals R ¹ , R ³ and R ⁴ independently of one another are hydrogen radicals, methyl radicals or ethyl radicals, preferably methyl radicals, then a preferred embodiment of the invention is present.

It could be found quite unexpectedly that when washing or cleaning agents according to the invention are used, a very distinct and unforeseen performance improvement in the removal of soils, which are based in particular on motor oil, occurs, in particular in manual or automatic textile washing. It is particularly advantageous that not only the removability of soils based on engine oil is improved, but that in addition the removability of other soiling, in particular of pigment-containing as well as greasy or oily soils, is unexpectedly improved becomes. This concerns in particular the removability of stains, which are due in particular to garden soil, make-up or skin fat.

Very particular preference is given to detergents or cleaning compositions according to the invention which comprise at least one amidine compound of the formula (1), as described above.

In a preferred embodiment of the invention, a washing or cleaning agent according to the invention contains from 0.01% by weight to 25% by weight, preferably from 0.1 to 20% by weight, advantageously from 0.5 to 10% by weight, in particular 1 wt .-% to 5 wt .-% of an amidine compounds having the formula (1) and / or a Amidiniumbicarbonates according to the formula (2), wt .-% based on the total agent.

Particularly preferred are alkyl sulfates having a lower Kratft point, preferably with Krafft point less than 45, 40, 30 or 2O ⁰ C. Krafft point is the term for the temperature at which the solubility of surfactants greatly increases due to the formation of micelles. The Krafft point is a triple point at which the solid or hydrated crystals of the surfactant are in equilibrium with its dissolved (hydrated) monomers and micelles. The Krafft point is determined by a turbidity measurement in accordance with DIN EN 13955: 2003-03.

A reasonable upper limit of zeolite may e.g. at 60 wt .-%, 50 wt .-% or 40 wt .-%, based on the total agent. This corresponds to a preferred embodiment of the invention.

For the purposes of the invention, the term "builder system" also encompasses those "systems" which consist only of a single builder, such as e.g. Zeolite. It is preferred, however, that at least 2 substances with a builder effect be used, e.g. Zeolite in combination with soda, or similar.

It is likewise particularly preferred if the washing or cleaning agent according to the invention contains a soluble builder system, preferably comprising soda, silicate, citrate and / or polycarboxylates, advantageously in amounts of from 0.1 to 50% by weight, based on the total agent , This corresponds to a preferred embodiment of the invention.

It is particularly advantageous that even at low temperatures, for example <4O ⁰ C or <3O ⁰ C, very good cleaning performance can be provided, in particular soiling related, which are due to engine oil. Of course, it is also possible to choose higher wash temperatures than 6O ⁰ C, for example 9O ⁰ C. Even then, very good cleaning performance can be achieved. Advantageously, such high temperatures but according to the invention are not necessary in order to come to excellent cleaning performance, so that energy can be saved. The textile washing process can be carried out either manually or automatically, ie in an automatic washing machine.

As has already been stated, the washing or cleaning agents according to the invention can comprise one or more surfactants, in particular anionic surfactants, nonionic surfactants and mixtures thereof, as well as cationic, zwitterionic and amphoteric surfactants.

Suitable nonionic surfactants are in particular alkyl glycosides and ethoxylation and / or propoxylation of alkyl glycosides or linear or branched alcohols each having 12 to 18 carbon atoms in the alkyl moiety and 3 to 20, preferably 4 to 10 alkyl ether groups. Furthermore, corresponding ethoxylation and / or propoxylation of N-alkyl-amines, vicinal diols, fatty acid esters and fatty acid amides, which correspond to said long-chain alcohol derivatives with respect to the alkyl moiety, and of alkylphenols having 5 to 12 carbon atoms in the alkyl radical.

The nonionic surfactants used are preferably alkoxylated, advantageously ethoxylated, in particular primary, alcohols having preferably 8 to 18 carbon atoms and on average 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol radical can be linear or preferably methyl-branched in the 2-position or may contain linear and methyl-branched radicals in the mixture, as they are usually present in Oxoalkoholresten. In particular, however, alcohol ethoxylates with linear radicals of alcohols of natural origin having 12 to 18 carbon atoms, for example of coconut, palm, tallow or oleyl alcohol, and on average 2 to 8 EO per mole of alcohol are preferred. Preferred ethoxylated alcohols include, for example, Ci ₂ - C ₄ alcohols containing 3 EO or 4 EO, C ₉ -C i-alcohols containing 7 EO, C ₃ -C ₅ alcohols containing 3 EO, 5 EO, 7 EO or 8 EO, Ci ₂ -Ci ₈ alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of Ci ₂ -Ci ₄ alcohol with 3 EO and Ci ₂ -Ci ₈ alcohol with 7 EO. The stated degrees of ethoxylation represent statistical averages, which for a particular product a whole or a fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow rank ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples of these are (TaIg) fatty alcohols with 14 EO, 16 EO, 20 EO, 25 EO, 30 EO or 40 EO. In particular, agents for use in mechanical processes usually extremely low-foam compounds are used. These preferably include Ci ₂ -C ₈ -Alkylpolyethylenglykol- polypropylene glycol ethers containing up to 8 moles of ethylene oxide and propylene oxide units in the molecule. One can also use other known low-foaming nonionic surfactants such as C ₂ -C ₁₈ alkyl polyethylene glycol polybutylene each having up to 8 moles of ethylene oxide and butylene oxide units in the molecule and end-capped alkylpolyalkylene glycol mixed ethers. Also particularly preferred are the hydroxyl-containing alkoxylated alcohols, as described in European Patent Application EP 0 300 305, so-called hydroxy mixed ethers. The nonionic surfactants also include alkyl glycosides of the general formula RO (G) _x, in which R is a primary straight-chain or methyl-branched, in particular 2-methyl-branched aliphatic radical having 8 to 22, preferably 12 to 18 carbon atoms and G is a Glykoseeinheit with 5 or 6 C-atoms, preferably for glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is an arbitrary number - which, as a variable to be determined analytically, may also assume fractional values - between 1 and 10; preferably x is 1, 2 to 1, 4. Also suitable are polyhydroxy fatty acid amides of the formula (III) in which R ^{1 is} CO for an aliphatic acyl radical having 6 to 22 carbon atoms, R ^{2 is} hydrogen, an alkyl or hydroxyalkyl radical having 1 to 4 carbon atoms and [Z] is a linear or branched polyhydroxyalkyl radical having 3 to 10 carbon atoms and 3 to 10 hydroxyl groups:

[Z] is also obtained here preferably by reductive amination of a sugar such as glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds can then be converted into the desired polyhydroxy fatty acid amides, for example by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst. Another class of preferably usable nonionic surfactants, which can be used either as the sole nonionic surfactant or in combination with other nonionic surfactants, in particular together with alkoxylated fatty alcohols and / or alkyl glycosides, are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably with 1 to 4 carbon atoms in the alkyl chain, especially fatty acid methyl ester. Nonionic surfactants of the amine oxide type, for example N-cocoalkyl-N, N-dimethylamine oxide and N-tallowalkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanolamides may also be suitable. The amount of these nonionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, especially not more than half thereof. Other suitable surfactants are so-called gemini surfactants. These are generally understood as meaning those compounds which have two hydrophilic groups per molecule. These groups are usually separated by a so-called "spacer". This spacer is typically a carbon chain that should be long enough for the hydrophilic groups to be spaced sufficiently apart for them to act independently of each other. Such surfactants are generally characterized by an unusually low critical micelle concentration and the ability to greatly reduce the surface tension of the water. In exceptional cases, the term gemini surfactants not only such "dimer", but also corresponding to "trimeric" surfactants understood. Suitable gemini surfactants are, for example, sulfated hydroxy mixed ethers or dimer alcohol bis- and trimer tris sulfates and ether sulfates. End-capped dimeric and trimeric mixed ethers are characterized in particular by their antibiotic activity. Thus, the end-capped surfactants mentioned have good wetting properties and are low foaming, so that they are particularly suitable for use in machine washing or cleaning processes. However, it is also possible to use gemini-polyhydroxy fatty acid amides or poly-polyhydroxy fatty acid amides. Also suitable are the Schwefelsäuremonoester the ethoxylated with 1 to 6 moles of ethylene oxide, linear or branched C ₇ -C ₂ i-alcohols such as 2-methyl-branched C ₉ -CN alcohols containing on average 3.5 mol ethylene oxide (EO) or C ₂ - Ci ₈ fatty alcohols with 1 to 4 EO. The preferred anionic surfactants also include the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters, and the monoesters and / or Diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols represent. Preferred sulfosuccinates contain C ₈ - to C ₈ - fatty alcohol radicals or mixtures thereof. Particularly preferred sulfosuccinates contain a fatty alcohol residue derived from ethoxylated fatty alcohols, which by themselves are nonionic surfactants. Sulfosuccinates, whose fatty alcohol residues are derived from ethoxylated fatty alcohols with a narrow homolog distribution, are again particularly preferred. Likewise, it is also possible to use alk (en) ylsuccinic acid having preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof. Suitable further anionic surfactants are fatty acid derivatives of amino acids, for example N-methyltaurine (Tauride) and / or N-methylglycine (sarcosides). Particularly preferred are the sarcosides or the sarcosinates and here especially sarcosinates of higher and optionally monounsaturated or polyunsaturated fatty acids such as oleyl sarcosinate. As further anionic surfactants are particularly soaps into consideration. Particularly suitable are saturated fatty acid soaps, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid and, in particular, soap mixtures derived from natural fatty acids, for example coconut, palm kernel or tallow fatty acids. Together with these soaps or as a substitute for soaps, it is also possible to use the known alkenylsuccinic acid salts.

The anionic surfactants, including soaps, may be in the form of their sodium, potassium or ammonium salts and as soluble salts of organic bases, such as mono-, di- or triethanolamine. The anionic surfactants are preferably present in the form of their sodium or potassium salts, in particular in the form of the sodium salts.

A particularly preferred acrylic acid-maleic acid copolymer has a molecular weight of from 30,000 to 100,000. Commercially available products are, for example, Sokalan® CP 5, CP 10 and PA 30 from BASF. Suitable, although less preferred, compounds of this class are copolymers of acrylic acid or methacrylic acid with vinyl ethers, such as vinylmethyl ethers, vinyl esters, ethylene, propylene and styrene, in which the proportion of the acid is at least 50% by weight. It is also possible to use terpolymers which contain two unsaturated acids and / or salts thereof as monomers and also vinyl alcohol and / or an esterified vinyl alcohol or a carbohydrate as the third monomer as water-soluble organic builder substances. The first acidic monomer or its salt is derived from a monoethylenically unsaturated C ₃ -C ₈ -carboxylic acid and preferably from a C ₃ -C ₄ -monocarboxylic acid, in particular from (meth) acrylic acid. The second acidic monomer or its salt may be a derivative of a C ₄ -C ₈ -dicarboxylic acid, with maleic acid being particularly preferred, and / or a derivative of an alkylsulfonic acid which is substituted in the 2-position by an alkyl or aryl radical , Such polymers generally have a molecular weight between 1,000 and 200,000. Further preferred copolymers are those which preferably have as monomers acrolein and acrylic acid / acrylic acid salts or vinyl acetate. The organic builder substances can be used, in particular for the preparation of liquid agents, in the form of aqueous solutions, preferably in the form of 30 to 50 percent by weight aqueous solutions.
