Definitions
- the invention relates to a liquid, low-phosphate and therefore environmentally friendly detergent which contains washing-active sulfonates, salts of fatty acids, nonionic surfactants, inorganic silicates and sequestering agents.
- DE-A-2530727 discloses a detergent which is free from phosphates and nitrilotriacetic acid and which contains washing-active sulfonates, nonionic polyglycol ethers, fatty acids and inorganic silicates and a content of 5 to 40% tall oil fatty acid or another saturated and / or unsaturated fatty acid at least 10 carbon atoms, 2 to 40% alkanesulfonate and / or alkylarylsulfonate, 10 to 50% of ethoxylated fatty alcohol with 3 to 8 mol of ethylene oxide and / or ethoxylated alkylphenol, and 5 to 60% of a quaternized fatty amine polyglycol ether based on higher fatty amines, the Ethylene oxide degree is about 10.
- Such detergents are particularly suitable for cleaning heavily oil and grease soiled textiles; they can be referred to as high-performance detergent preparations.
- the present invention is therefore based on the object of finding such a detergent which is capable of achieving a solids content of more than 50%, based on the total detergent, in a liquid combination of surfactants with certain builders.

Die Erfindung betrifft ein flüssiges, phosphatarmes und damit umweltfreundliches Waschmittel, das waschaktive Sulfonate, Salze von Fettsäuren, nichtionische Tenside, anorganische Silikate und Sequestriermittel enthält.The invention relates to a liquid, low-phosphate and therefore environmentally friendly detergent which contains washing-active sulfonates, salts of fatty acids, nonionic surfactants, inorganic silicates and sequestering agents.
Bekannt ist aus der DE-A-2530727 ein von Phosphaten und Nitrilotriessigsäure freies Waschmittel, das waschaktive Sulfonate, nicht-ionische Polyglykoläther, Fettsäuren und anorganische Silikate enthält und einen Gehalt von 5 bis 40% Tallölfettsäure oder einer anderen gesättigten und/oder ungesättigten Fettsäure mit mindestens 10 C-Atomen, 2 bis 40% Alkansulfonat und/oder Alkylarylsulfonat, 10 bis 50% an äthoxiliertem Fettalkohol mit 3 bis 8 Mol Äthylenoxyd und/oder äthoxiliertem Alkylphenol, sowie 5 bis 60% eines quarternisierten Fettaminpolyglykoläthers auf der Basis höherer Fettamine, dessen Äthylenoxydgrad etwa 10 beträgt, aufweist.DE-A-2530727 discloses a detergent which is free from phosphates and nitrilotriacetic acid and which contains washing-active sulfonates, nonionic polyglycol ethers, fatty acids and inorganic silicates and a content of 5 to 40% tall oil fatty acid or another saturated and / or unsaturated fatty acid at least 10 carbon atoms, 2 to 40% alkanesulfonate and / or alkylarylsulfonate, 10 to 50% of ethoxylated fatty alcohol with 3 to 8 mol of ethylene oxide and / or ethoxylated alkylphenol, and 5 to 60% of a quaternized fatty amine polyglycol ether based on higher fatty amines, the Ethylene oxide degree is about 10.
Solche Waschmittel eignen sich insbesondere zur Reinigung von stark öl- und fettverschmutzten Textilien; sie können als Hochleistungs- Waschdetergenz-Zubereitung bezeichnet werden.Such detergents are particularly suitable for cleaning heavily oil and grease soiled textiles; they can be referred to as high-performance detergent preparations.
Diese bekannten Waschmittel sind jedoch nicht dazu bestimmt, Weiß- und Buntwäsche faserschonend und ohne Erhöhen des Aschegehalts des fünfzigmal gewaschenen Waschguts zu reinigen. Zur Erlangung des Gütezeichens für sachgemäße Wäschepflege (RAL-RG 922) ist es nämlich notwendig, daß das Waschgut nach fünfzigmaliger Wäsche einen Schädigungsfaktor <1, einen geringeren Reißkraftverlust als 30%, sowie einen maximalen Aschegehalt von 1 % aufweist.However, these known detergents are not intended to clean white and colored laundry gently and without increasing the ash content of the laundry washed 50 times. In order to obtain the quality label for proper laundry care (RAL-RG 922), it is necessary for the laundry to have a damage factor of <1 after 50 washings, a loss of tensile strength less than 30%, and a maximum ash content of 1%.
Vorliegender Erfindung liegt daher die Aufgabe zugrunde ein solches Waschmittel zu finden, das in der Lage ist, in einer flüssigen Kombination von Tensiden mit bestimmten Gerüstsubstanzen einen Feststoffgehalt von mehr als 50% bezogen auf das Gesamtwaschmittel zu erreichen. Ferner soll das Waschmittel ein hervorragendes Emulgiervermögen für Fette und Öle besitzen, und es soll darüber hinaus für die vollständige Reinigung von Weiß- und Buntwäsche verwendet werden können, d.h. es liegt vorliegender Erfindung die Aufgabe zugrunde, bei einem Waschmittel der eingangs genannten Gattung zu erreichen, daß auch empfindliches Waschgut nach fünfzigmaliger Wäsche einen Schädigungsfaktor <1, einen geringeren Reißkraftverlust als 30% sowie einen maximalen Aschegehalt von 1 % aufweist.The present invention is therefore based on the object of finding such a detergent which is capable of achieving a solids content of more than 50%, based on the total detergent, in a liquid combination of surfactants with certain builders. Furthermore, the detergent is said to have an excellent emulsifying power for fats and oils, and it should also be able to be used for the complete cleaning of white and colored laundry, i.e. It is an object of the present invention to achieve in a detergent of the type mentioned at the outset that even delicate items to be washed after fifty washes have a damage factor <1, a loss of tensile strength less than 30% and a maximum ash content of 1%.
Diese Aufgabe wird bei dem Waschmittel der eingangs genannten Gattung erfindungsgemäß dadurch gelöst, daß das Waschmittel durch einen Gehalt von 2 bis 40 Gew.-% Alkansulfonaten sowie von 5 bis 98 Gew.-% an nicht-ionischen Tensiden, bezogen auf die Tensidkombination, sowie durch einen Gehalt an Sequestriermittel, deren Natur weiter unten noch im einzelnen beschrieben wird, gekennzeichnet ist.This object is achieved according to the invention in the detergent of the type mentioned at the outset in that the detergent has a content of 2 to 40% by weight of alkanesulfonates and 5 to 98% by weight of nonionic surfactants, based on the surfactant combination, and is characterized by a content of sequestering agent, the nature of which will be described in detail below.
Nach einer bevorzugten Ausführungsform ist das erfindungsgemäße Waschmittel dadurch gekennzeichnet, daß es als nicht-ionische Tenside Äthoxilierungsprodukte von ein und/oder mehrwertigen Alkoholen, Aminen, Carbonsäuren und Carbonsäureamiden mit jeweils 6 bis 20 C-Atomen enthält.According to a preferred embodiment, the detergent according to the invention is characterized in that it contains, as non-ionic surfactants, ethoxylation products of mono- and / or polyhydric alcohols, amines, carboxylic acids and carboxamides, each having 6 to 20 carbon atoms.
Eine weitere bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß der Äthoxilierungsgrad der nichtionischen Tenside 2 bis 20 Mol Äthylenoxyd beträgt.A further preferred embodiment is characterized in that the degree of ethoxylation of the nonionic surfactants is 2 to 20 moles of ethylene oxide.
Nach einer weiteren Ausführungsform ist das erfindungsgemäße Mittel dadurch gekennzeichnet, daß es als nicht-ionische Tenside Fettalkoholpolyglykoläther mit 6 bis 18 C-Atomen und einem Äthoxilierungsgrad von 7 bis 10 Mol Äthylenoxyd enthält.According to a further embodiment, the agent according to the invention is characterized in that it contains, as non-ionic surfactants, fatty alcohol polyglycol ether having 6 to 18 carbon atoms and a degree of ethoxylation of 7 to 10 mol of ethylene oxide.
Eine weitere bevorzugte Ausführungsform des erfindungsgemäßen Waschmittels ist schließlich dadurch gekennzeichnet, daß es als nicht-ionische Tenside Nonylphenoläthoxylate mit einem Äthoxilierungsgrad von 2 bis 20, vorzugsweise von 7 bis 10 Mol Athylenoxyd enthält.A further preferred embodiment of the detergent according to the invention is finally characterized in that it contains nonylphenol ethoxylates as nonionic surfactants with a degree of ethoxylation of 2 to 20, preferably 7 to 10, moles of ethylene oxide.
Eine weitere bevorzugte Ausführungsform des Erfindungsgegenstandes ist dadurch gekennzeichnet, daß das Waschmittel als Sequestriermittel höherpolymere Natriumphosphate der Formel (NaP0,)", wobei n größer oder gleich 3 ist, enthält, und zwar vorzugsweise Natriumhexametaphosphate und/oder Salze von Aminocarbonsäuren und/oder Salze von Polycarbonsäuren.A further preferred embodiment of the subject matter of the invention is characterized in that the detergent as sequestering agent contains higher polymer sodium phosphates of the formula (NaP0,) " , where n is greater than or equal to 3, preferably sodium hexametaphosphates and / or salts of aminocarboxylic acids and / or salts of Polycarboxylic acids.
Es war nämlich bisher nicht möglich, in flüssige, silikatische Builder mit Feststoffgehalten >10% handelsübliche, polymere Phosphate in höherer Konzentration als Sequestriermittel einzuarbeiten. Bei den als Buildersubstanzen handelsüblichen polymeren Phosphaten handelt es sich um Natriumpyro-und Natriumtripolyphosphate. Beim Vereinigen flüssiger silikatischer Builder mit Lösungen der handelsüblichen polymeren Phosphate treten Trübungen, Niederschläge und Kristallisationserscheinungen auf.It has so far not been possible to incorporate commercially available polymeric phosphates in higher concentrations as sequestering agents into liquid, silicate builders with solids contents> 10%. The polymeric phosphates commercially available as builder substances are sodium pyrophosphates and sodium tripolyphosphates. When liquid silicate builders are combined with solutions of the commercially available polymeric phosphates, turbidity, precipitation and signs of crystallization occur.
Es war bislang allenfalls möglich, verdünnte Kaliumphosphatlösungen mit verdünnten Kaliumsilikatlösungen lagerstabil zu vereinigen, da es keine kristallisierenden Kaliumsilikate gibt. Auf dem Gebiet der polymeren Phosphate und Silikate sind Kalium- und Natriumsalze nicht äquivalent.Until now, it was at best possible to combine dilute potassium phosphate solutions with dilute potassium silicate solutions in a storage-stable manner, since there are no crystallizing potassium silicates. In the field of polymeric phosphates and silicates, potassium and sodium salts are not equivalent.
Natriumsilikate und Natriumphosphate ziechnen sich außerdem gegenüber den entsprechenden Kaliumverbindungen durch einen wesentlich geringeren Preis, d.h. durch eine höhrere Wirtschaftlichkeit der ausgehend von Natriumverbindungen aufgebauten Waschmittel aus.Sodium silicates and sodium phosphates also have a significantly lower price than the corresponding potassium compounds, i.e. due to the higher efficiency of the detergents based on sodium compounds.
Es liegt also vorliegender Erfindung die überraschende Erkenntnis zugrunde, daß bestimmte Sequestriermittel bzw. deren Lösungen mit Natriumsilikatlösungen, welche 60 Gew.-% Feststoff, gerechnet als Gewichtsprozent Na20 plus Gewichtsprozent Si02, enthalten, lagerstabil vereinigt werden können.The present invention is therefore based on the surprising finding that certain sequestering agents or their solutions can be combined with sodium silicate solutions which contain 60% by weight of solids, calculated as percent by weight Na 2 0 plus percent by weight Si0 2 , in a storage-stable manner.
Sequestriermittel im Sinne vorliegender Offenbarung sind höherpolymere Natriumphosphate der Formel (Nap03)1, wobei n größer oder gleich 3 ist und wobei sowohl Ketten- als auch Ringgruppierungen vorliegen können. Der Feinbau derartiger Polymerphosphate ist bislang noch nicht restlos geklärt.Sequestrants in the sense of the present disclosure are higher polymer sodium phosphates of the formula (Na p 0 3 ) 1 , where n is greater than or equal to 3 and both chain and ring groups can be present. The fine structure of such polymer phosphates has not yet been completely clarified.
Insbesondere wirken als Sequestriermittel im Sinne der Erfindung Natriumhexametaphosphate mit Kettenlängen von mehr als sechs P04-Gruppen. Diese sind langkettige Hexametaphosphate mit mittleren Kettenlängen um 20. Sie wirken im erfindungsgemäßen Waschmittel bzw. bei dieser Anwendung im Waschverfahren bereits in geringer Konzentration als hervorrangende Sequestriermittel und Builderkomponenten, die mit hochkonzentrierten flüssigen Waschmitteln ein äußerst wäscheschonendes Waschen von empfindlichem Waschgut ermöglichen.In particular, sodium hexametaphosphates with chain lengths of more than six P0 4 groups act as sequestering agents in the sense of the invention. These are long-chain hexametaphosphates with average chain lengths around 20. In the detergent according to the invention or in this application in the washing process, they act even in low concentrations as excellent sequestering agents and builder components which, with highly concentrated liquid detergents, enable delicate laundry to be washed in an extremely gentle manner.
Das Mischungsverhältnis von Natriumhexametaphosphat und Natriumsilikatlösungen kann in weiten Grenzen variiert werden; so sind beispielsweise Natriumsilikatlösungen mit einer Dichte von 59/60° B6 mit 60-%-iger Natriumhexametaphosphatlösung unbeschränkt mischbar.The mixing ratio of sodium hexametaphosphate and sodium silicate solutions can be varied within wide limits; For example, sodium silicate solutions with a density of 59/60 ° B6 can be mixed with 60% sodium hexametaphosphate solution without restriction.
Der Einsatz von Phosphaten in Waschmitteln wird in der Bundesrepublik Deutschland und anderem europäischen Ländern bzw. den Niederlanden vom Gesetzgeber aus ökologischen Gründen beschränkt. Mit der erfindungsgemäßen Builderkombination aus Alkalisilikat und Natriumhexametaphosphaten lassen sich jedoch die waschtechnischen Vorteile der Phosphatkomponente, wie Sequestriervermögen, Emulgiervermögen, Schutztragevermögen usw. mit so geringen Phosphatgehalten erreichen, daß die vom Gesetzgeber vorgesehenen Maximalgehalte in Gramm Phosphor pro Liter Waschflotte ohne weiteres unterschritten werden können.Legislation restricts the use of phosphates in detergents in the Federal Republic of Germany and other European countries and the Netherlands for ecological reasons. With the builder combination of alkali silicate and sodium hexametaphosphates according to the invention, however, the washing-related advantages of the phosphate component, such as sequestering ability, emulsifying power, protective load-bearing capacity, etc. can be achieved with such low phosphate contents that the maximum levels in grams of phosphorus per liter of washing liquor prescribed by law can easily be fallen short of.
Weitere Sequestriermittel im Sinne der Erfindung sind Salze der Nitrilotriessigsäure, Salze der Äthylendiamintetraessigsäure bzw. ähnlich aufgebaute Amincarbonsäuren, ferner Salze von Polycarbonsäuren, wie Glukonate, Heptonate oder Citrate.Further sequestering agents within the meaning of the invention are salts of nitrilotriacetic acid, salts of ethylenediaminetetraacetic acid or a similarly structured amine carboxylic acid, furthermore salts of polycarboxylic acids, such as gluconates, heptonates or citrates.
Ein Zusatz von Aminocarbonsäuren zum erfindungsgemäßen Waschmittel wirkt außerdem als Sauerstoffstabilisator bei Zusatz oxidativer Bleichmittel im Waschverfahren.The addition of amino carboxylic acids to the detergent according to the invention also acts as an oxygen stabilizer when oxidative bleaching agents are added in the washing process.
Anorganische Silikate im Sinne der vorliegenden Erfindung sind gekennzeichnet durch eine Zusammensetzung
Die Werte für x und y liegen zwischen 1 und 8; das Verhältnis y:x bewegt sich von 0,5 bis 8. Der Wassergehalt ist durch den Koeffizienten z gegeben. Er bewegt sich von 0 im Fall der wasserfreien Silikate bis etwa 20 im Falle flüssiger Wasserglässer.The values for x and y are between 1 and 8; the ratio y: x ranges from 0.5 to 8. The water content is given by the coefficient z. It ranges from 0 in the case of anhydrous silicates to about 20 in the case of liquid water glasses.

Das C-Gerüst der Moleküle, an welche Äthylenoxid angelagert wird, besteht aus 6 bis 20 C-Atomen. An ein Molekül-Substrat können 2 bis 20 Moleküle Äthylenoxyd, vorzugsweise 7 bis 12 Moleküle Äthylenoxyd angelagert sein. Besonders bevorzugt in Sinne der vorliegenden Erfindung sind Äthylenoxyd-Anlagerungsprodukte synthetischer oder aus natürlichen Fetten gewonnener Fettalkohole mit 6 bis 18 C-Atomen, wobei der Äthylenoxydgrad 7 bis 10 beträgt. Ferner sind als nicht-ionische Tenside im Sinne der vorliegenden Erfindung Nonylphenoläthoxylate mit einem Äthoxylierungsgrad von vorzugsweise 7 bis 10 Mol Äthylenoxyd/Mol Nonylphenol besonders bevorzugt. Anstelle von Äthylenoxid kann auch Propylenoxid treten.Non-ionic surfactants for the purposes of the present invention are ethylene oxide adducts and monohydric and / or polyhydric alcohols of the aliphatic series and on aromatically substituted aliphatic alcohols, furthermore on amines, carboxylic acids and carboxamides. The carbon skeleton of the molecules to which ethylene oxide is attached consists of 6 to 20 carbon atoms. 2 to 20 molecules of ethylene oxide, preferably 7 to 12 molecules of ethylene oxide, can be attached to a molecule substrate. For the purposes of the present invention, particular preference is given to ethylene oxide addition products of synthetic alcohols or fatty alcohols having 6 to 18 carbon atoms and obtained from natural fats, the degree of ethylene oxide being 7 to 10. Furthermore, nonylphenol ethoxylates with a degree of ethoxylation of preferably 7 to 10 moles of ethylene oxide / mole of nonylphenol are particularly preferred as nonionic surfactants for the purposes of the present invention.
