Abstract

Controlled-foaming detergent composition, based on an anionic detergent or a combination of an anionic detergent and a nonionic detergent, having a mono- and/or dialkyl orthophosphate content, of which the alkyl group has 12-22 carbon atoms or of which the alkyl group is separated from the P-atom by up to 6 alkylene oxide groups, characterized in that it further has a metal soap content originating from di- or trivalent metal cations.

Description

Die vorliegende Anmeldung bezieht sich auf schaumkontrollierte Waschmittel.The present application relates to foam-controlled detergents.

Waschmittel, die für den Gebrauch in (Haushalts)-Waschmaschinen, insbesondere in Trommelmaschinen geeignet sein sollen, dürfen unter allen in der Praxis vorkommenden Bedingungen nicht so viel Schaum entwickeln, dass dabei ein Ueberschäumen aus der Waschmaschine auftreten könnte.Detergents, which should be suitable for use in (household) washing machines, especially in drum machines, must not develop so much foam under all conditions that occur in practice that excessive foaming from the washing machine could occur.

Im Stande der Technik sind schon zahlreiche Vorschläge zur Herstellung solcher schaumkontrollierten Waschmittel gemacht worden, die vom Effekt her befriedigend sind, aber auf andere Parameter, wie z.B. Löslichkeit und Schaumverhalten bei Handwäschen, Einspülverhalten in der Waschmaschine, Verbraucherakzeptanz usw. nicht vollbefriedigende Auswirkungen haben oder ihre Wirksamkeit bei der Lagerung verlieren können. Hierdurch wird die Wahl der bezüglich der Reinigungswirkung optimalen Waschaktivsubstanz (WAS) oder von WAS-Kombinationen eingeschränkt.Numerous proposals have already been made in the prior art for the production of such foam-controlled detergents, which are satisfactory in terms of their effect, but are based on other parameters, such as e.g. Solubility and foam behavior during hand washing, washing-up behavior in the washing machine, consumer acceptance etc. may not have fully satisfactory effects or may lose their effectiveness during storage. As a result, the choice of the optimal detergent active substance (WAS) or of WAS combinations is restricted.

Die vorliegende Erfindung erlaubt nun die Verwendung von in ihrem technischen Verhalten und kostenmässig optimalen WAS-Substanzen oder ihren Kombinationen, ohne durch deren Schaumverhalten in ihrer Wahl stark eingeschränkt zu sein. Bei Vollwaschmitteln, die bei allen Temperaturen verwendet werden können sollen, ist ausserdem bei verschiedenen Temperaturen ein unterschiedliches Schaumverhalten erwünscht. Es wurde nun gefunden, dass der angestrebte Zweck erreicht werden kann, indem einem Waschmittel eine Mischung aus Metallseifen und Alkylphosphaten zugefügt wird. Es kann durch geeignete Auswahl der Bestandteile, die über den gesamten Temperaturbereich von ca. 20-100°C unterschiedliche Einzelcharakteristika aufweisen, durch Zusammenwirkung ihrer sich auch gegenseitig beeinflussenden Eigenschaften das gewünschte Schaumprofil eingestellt werden.The present invention now allows the use of WAS substances or their combinations which are optimal in their technical behavior and in terms of cost, without being severely restricted in their choice by their foaming behavior. In the case of heavy-duty detergents that should be able to be used at all temperatures, different foaming behavior is also desirable at different temperatures. It has now been found that the intended purpose can be achieved by adding a mixture of metal soaps to a detergent and alkyl phosphates is added. The desired foam profile can be set by a suitable selection of the components, which have different individual characteristics over the entire temperature range of approx. 20-100 ° C., by the interaction of their mutually influencing properties.

Es ist aus der DT-AS 1.089.905 schon bekannt eine Mischung von Metallseifen und nichtionogenen Tensiden als nicht-schäumendes Waschmittel zu verwendenIt is already known from DT-AS 1.089.905 to use a mixture of metal soaps and nonionic surfactants as a non-foaming detergent

Alkylphosphate sind ebenfalls schon in niedrigschäumenden Waschmitteln vorgeschlagen worden, meistens zusammen mit nichtionogenen Tensiden (DT-OS 2.701.663; DT-OS 2.532.804; DT-OS 2.537.570). Die Verwendung von Mischungen aus Metallseifen und Alkylphosphaten ist aber diesem Stande der Technik nicht zu entnehmen. Unter Metallseifen sind Seifen mit zwei- oder dreiwertigen Hatallkationen zu verstehen.Alkyl phosphates have also already been proposed in low-foaming detergents, mostly together with nonionic surfactants (DT-OS 2,701,663; DT-OS 2,532,804; DT-OS 2,537,570). The use of mixtures of metal soaps and alkyl phosphates cannot be deduced from this prior art. Metal soaps are to be understood as meaning soaps with divalent or trivalent hatall cations.

Die Metallseifen, die gemäss der Erfindung eingesetzt werden können, sind solche Metallseifen, die bis zu der maximalen Temperatur, bei der sie noch effektiv sein sollen, durch genügend lange C-Ketten und Vermeidung der Reversion in ihr Na-Salz im Waschprozess nicht in Lösung gehen können. Beispiele für geeignete Metallkationen sind u.a_. Ca, Mg, Al, Zn; Beispiele von geeigneten Fettsäuren, aus denen die Metallseifen hergestellt werden, sind die höhermolekularen (C12-C22 oder höher) Fettsäuren oder Gemische davon, wie Stearinsäure, Palmitinsäure und höhere Fettsäuren. Eine bevorzugte Metallseife ist Calciumstearat. Die Alkylphosphate, die erfindungsgemäss eingesetzt werden können, sind Mono- und/oder Dialkylorthophosphate, deren Alkylgruppe von 12-22 Kohlenstoffatome enthalten kann oder deren Alkylgruppe durch eine Anzahl von Alkylenoxidgruppen (bis zu 0) vom P-Atom getrennt sein kann. Die Alkylphosphate liegen als Alkalimetallsalze vor. Geeignete Beispiele sind C16-C18- Monoalkylphosphat (Natriumsalz), wie Stearylmonophosphat, Mischungen von Mono-und Distearylphosphat, Mono- und Dilaurylätherphosphat usw. Im allgemeinen werden die Metallseifen in einer Menge von 0,1 bis 3, vorzugsweise 0,5 biis 1,5 Gew.% des Waschmittels verwendet, und die Alkylphosphate in einer Menge von 0,05 bis 2, vorzugsweise 0,2 bis 1 Gew.%.The metal soaps which can be used according to the invention are those metal soaps which, up to the maximum temperature at which they are said to still be effective, are not in solution in the washing process due to sufficiently long C chains and avoidance of reversion into their Na salt can go. Examples of suitable metal cations include. Ca, Mg, Al, Zn; Examples of suitable fatty acids from which the metal soaps are produced are the higher molecular weight (C 12 -C 22 or higher) fatty acids or mixtures thereof, such as stearic acid, palmitic acid and higher fatty acids. A preferred metal soap is calcium stearate. The alkyl phosphates which can be used according to the invention are mono- and / or dialkyl orthophosphates, the alkyl group of which can contain from 12-22 carbon atoms or their Alkyl group can be separated from the P atom by a number of alkylene oxide groups (up to 0). The alkyl phosphates are present as alkali metal salts. Suitable examples are C 16 -C 18 monoalkyl phosphate (sodium salt), such as stearyl monophosphate, mixtures of mono- and distearyl phosphate, mono- and dilauryl ether phosphate, etc. In general, the metal soaps are used in an amount of 0.1 to 3, preferably 0.5 to 15 1.5% by weight of the detergent, and the alkyl phosphates in an amount of 0.05 to 2, preferably 0.2 to 1% by weight.

Die erfindungsgemässe Mischung von Metallseifen und Alkylphosphaten wird dem Waschmittel vorzugsweise sekundär zugefügt. Beispiele für geeignete Verfahren sind sekundäres Aufsprühen von in nichtionogenem Tensid dispergierten Metallseifen und Alkylphosphaten auf das Waschmittelpulver, wobei eine homogene Durchmischung durch verschiedene Massnahmen (wie z.B. Ultraschall) anzustreben ist; Granulation von Metallseifen und Alkylphosphaten und sekundäre Zugabe dieses granulierten ten Gemisches zum Waschmittelpulver; Einkapsulation von Dispersionen von Metallseifen und Alkylphosphaten und sekundäre Zugabe dieses einkapsulierten Gemisches zum Waschmittelpulver; Verstäuben der Metallseifen und Alkylphosphate auf das noch klebrige Waschmittelpulver usw.The mixture of metal soaps and alkyl phosphates according to the invention is preferably added to the detergent as a secondary. Examples of suitable processes are secondary spraying of metal soaps and alkylphosphates dispersed in nonionic surfactant onto the detergent powder, homogeneous mixing being attempted by various measures (such as ultrasound); Granulation of metal soaps and alkyl phosphates and secondary addition of this granulated mixture to the detergent powder; Encapsulation of dispersions of metal soaps and alkyl phosphates and secondary addition of this encapsulated mixture to the detergent powder; Dusting the metal soaps and alkyl phosphates on the still sticky detergent powder etc.

Vorzugsweise werden die Metallseife und das Alkylphosphat in einem nichtionogenen Tensid dispergiert, und wird diese Dispersion auf das Waschmittelpulver sekundär aufgesprüht.Preferably, the metal soap and the alkyl phosphate are dispersed in a nonionic surfactant, and this dispersion is sprayed onto the detergent powder secondarily.

Wie schen vorher erwähnt, erlaubt die Erfindung die Verwendung einer optimalen WAS im Waschmittel. Dabei handelt es sich vor allem um rein anionogene Substanzen. Beispiele solcher anionogenen Substanzen sind üblicherweise wasserlösliche Alkalimetallsalze von organischen Sulfonaten oder Schwefelsäureestern, welche Alkylreste mit etwa 8 bis 22 Kolhenstoffatomen besitzen. Beispiele solcher synthetischen anionischen waschaktiven Verbindungen sind Natrium- oder Kaliumalkylschwefelsäureester, insbesondere solche, welche durch Sulfatieren von C8- bis C18-Fettalkoholen hergestellt werden können, die durch Reduktion von aus Talg oder Kokosnussöl stammenden Fettsäuren erhalten werden, oder von synthetischen Alkoholen, die z.B durch Oxo-Synthese oder Ziegler-Synthese gewonnen werden; Natrium- oder Kaliumalkyl-(C9-C20)-benzolsulfonate; insbesondere Natrium- lin.-sek.-alkyl (C10-C15)-benzolsulfonate; Natrium-oder Kalium-alkyl-polyglykoläther-schwefelsäureester, inbesondere aus Aethern von höheren Alkoholen, die aus Talg oder Kokosnussöl gewonnen werden, oder von synthetischen höheren Alkoholen; Natrium- oder Kaliumsalze von Fettsäuremonoglyceridsulfaten oder -sulfonaten; Reaktionsprodukte von Fettsäuren, z.B. Talg- oder Kokosfettsäure, mit Isethionsäure und mit Natrium-oder Kaliumhydroxid neutralisiert; Natrium- und Kaliumsalze von Fettsäuremethyltauriden; Alkanmonosulfonate, wie diejenigen, die durch Umsetzung von C8- bis C20-alpha-Olefinen mit Natriumhydrogensulfit oder durch Umsetzung von Paraffinen mit S02 und C12 bzw. O2 und:anschliessende Hydrolyse mit Natrium-oder Kaliumhydroxid erhalten werden, sowie Olefinsulfonate, wobei mit diesem Ausdruck das Material bezeichnet werden soll, welches durch Umsetzung von Olefinen, ins-. besondere alpha-Olefinen, mit S03 und anschliessender Hydrolyse und Neutralisatiion erhalten wird.As previously mentioned, the invention allows the Use of an optimal WAS in the detergent. Above all, these are purely anionogenic substances. Examples of such anionogenic substances are usually water-soluble alkali metal salts of organic sulfonates or sulfuric acid esters, which have alkyl radicals with about 8 to 22 carbon atoms. Examples of such synthetic anionic detergent compounds are sodium or potassium alkyl sulfuric acid esters, in particular those which can be prepared by sulfating C 8 to C 18 fatty alcohols which are obtained by reducing fatty acids derived from tallow or coconut oil, or from synthetic alcohols can be obtained, for example, by oxo synthesis or Ziegler synthesis; Sodium or potassium alkyl (C 9 -C 20 ) benzenesulfonates; in particular sodium lin.-sec.-alkyl (C 10 -C 15 ) benzene sulfonates; Sodium or potassium alkyl polyglycol ether sulfuric acid esters, in particular from ethers of higher alcohols which are obtained from tallow or coconut oil, or from synthetic higher alcohols; Sodium or potassium salts of fatty acid monoglyceride sulfates or sulfonates; Reaction products of fatty acids, eg tallow or coconut fatty acid, neutralized with isethionic acid and with sodium or potassium hydroxide; Sodium and potassium salts of fatty acid methyl taurides; Alkane monosulfonates, such as those obtained by reacting C 8 -C 20 -alpha-olefins with sodium bisulfite or by reacting paraffins with SO 2 and C1 2 or O 2 and: subsequent hydrolysis with sodium or potassium hydroxide, and also olefin sulfonates , With this expression the material is to be referred to, which by reacting olefins, ins. special alpha-olefins, with S0 3 and subsequent hydrolysis and neutralization is obtained.

Es hat cich aber gezeigt, dass die Erfindung insbesondere füz binäre WAS-Kombinationen geeignet ist, d.h.für Kombinationen eines anionogenen und eines nichtionogenen Tensids. Solche WAS-Kombinationen sind an sich durchaus bekannt, und enthalten die üblichen anionogenen und nichtionogenen Tenside in allen möglichen Mischungsverhältnissen und in einer Gesamtmenge bis zu über 30 Gew.%. Beispiele solcher nichtionogenen Tenside sind die Reaktionsprodukte von Alkylenoxid, insbesondere Aethylenoxid und/oder Propylenoxid, mit Alkyl (C6-C12)-phenolen, C8-C20-Alkanolen, Fettsäureamiden, wobei im allgemeinen 5 bis 30-Aethylenoxid-Einheiten pro Molekül vorliegen, Blockpolymerisate aus Propylenoxid und Aethylenoxid, Kondensationsprodukte von Aethylenoxid mit Reaktionsprodukten aus Propylenoxid mit Aethylendiamin, usw. Andere nichtionische waschaktive Verbindungen umfassen langkettige tertiäre Amin- oder Phosphinoxide und Dialkylsulfoxide. Beispiele solcher Kombinationen von anionogenen und nichtionogenen Tensiden sind Mischungen von Na-Dodecylbenzolsulfonat und Talgfettalkohol, mit 5 Mol EO kondensiert, oder von Na-Dodecylbenzolsulfonat und C12-C15-Oxo-Alkohol, mit 12-18 Mol EO kondensiert. Die Waschmittel können überdies die üblichen, weiteren Waschmittelbestandteile, wie organische und/oder anorganische Aufbausalze, in den üblichen Mengen enthalten. Beispiele von Aufbausalzen sind Phosphate, Zitrate. oxidierte Stärke- und Cellulosederivate, insbesondere solche mit Dicarboxylresten, Natriumalkenyl-(C10-C20)-succinate, Natriumsulfofettsäuren, Alkalimetallcarbonate, Natriumaluminiumsilikate, Carboxymethyloxysuccinate, Nitrilotriacetate usw. Andere konventionelle Materialien können in den erfindungsgemässen Reinigungsmittelzusammensetzungen in den üblichen Mengen vorliegen, z.B. Schmutzsuspendiermittel, Hydrotrope, Korrosionsinhibitoren, Farbstoffe, Duftstoffe,Füllstoffe, optische Aufheller, Enzyme, Schaumverstärker, Schaumunterdrücker, Germicide, Antianlaufmittel, Textilweichmacher, Chlor freisetzende Mittel, Sauerstoff freisetzende Bleichmittel, wie Natriumperborat oder -percarbonat mit oder ohne Persäurevorläuferverbindungen, Puffer und dergleichen. Der Rest der Reinigungsmittelzusammensetzungen besteht aus Wasser, z.B. im Bereich von etwa 5 bis 15% in den pulverförmigen Reinigungsmittelzusammensetzungen.However, it has shown that the invention is particularly suitable for binary WAS combinations, ie for combinations of an anionogenic and a nonionic surfactant. Such WAS combinations are well known per se and contain the usual anionogenic and nonionic surfactants in all possible mixing ratios and in a total amount of up to over 30% by weight. Examples of such nonionic surfactants are the reaction products of alkylene oxide, especially ethylene oxide A and / or propylene oxide, with alkyl (C 6 -C 12) phenols, C 8 -C 20 -alkanols, fatty acid amides, wherein in general from 5 to 30 ethylene oxide units present per molecule, block polymers of propylene oxide and ethylene oxide, condensation products of ethylene oxide with reaction products of propylene oxide with ethylenediamine, etc. Other nonionic detergent compounds include long-chain tertiary amine or phosphine oxides and dialkyl sulfoxides. Examples of such combinations of anionogenic and nonionogenic surfactants are mixtures of sodium dodecylbenzenesulfonate and tallow fatty alcohol, 5 EO M ol condensed, or condensed by Na-dodecyl benzene sulfonate and C 12 -C 15 oxo-alcohol, with 12-18 moles EO. The detergents can moreover contain the usual, further detergent constituents, such as organic and / or inorganic build-up salts, in the usual amounts. Examples of building salts are phosphates, citrates. Oxidized starch and cellulose derivatives, in particular those with dicarboxyl residues, sodium alkenyl (C 10 -C 20 ) succinates, sodium sulfofatty acids, alkali metal carbonates, sodium aluminum silicates, carboxymethyloxysuccinates, nitrilotriacetates etc. Other conventional materials can be present in the detergent compositions according to the invention, for example in the usual amounts of detergent compositions, for example in the usual amounts of detergent compositions , Hydrotropes, corrosion inhibitors, Dyes, fragrances, fillers, optical brighteners, enzymes, foam boosters, foam suppressants, germicides, anti-tarnish agents, fabric softeners, chlorine-releasing agents, oxygen-releasing bleaching agents such as sodium perborate or percarbonate with or without peracid precursor compounds, buffers and the like. The rest of the detergent compositions consist of water, for example in the range of about 5 to 15% in the powder detergent compositions.
