Description

Die vorliegende Erfindung betrifft eine flüssige Waschmittelzusammensetzung, insbesondere eine Waschmittelzusammensetzung, die aus mindestens zwei getrennt voneinander vorhandenen Teilzusammensetzungen (Komponenten) aufgebaut ist.The present invention relates to a liquid detergent composition, in particular a detergent composition, which is composed of at least two subcomponents (components) present separately from one another.

Bei Waschmitteln, die in flüssiger Form vorliegen, vor allem bei wasserhaltigen Waschmitteln, kann es zu Inkompatibilitäten zwischen einzelnen Bestandteilen des Waschmittels kommen, was zu unzulänglichen Lagerstabilitäten resp. Verschlechterung des Waschergebnisses führt. Ein grosses Inkompatibilitätsproblem besteht z.B. zwischen bevorzugten Bleichmitteln und Enzymen und/oder Tensiden.For detergents that are in liquid form, especially in aqueous detergents, it may cause incompatibilities between individual components of the detergent, resulting in insufficient storage stabilities, respectively. Deterioration of the washing result leads. A major incompatibility problem is e.g. between preferred bleaching agents and enzymes and / or surfactants.

Zur Vermeidung solcher Probleme ist bereits vorgeschlagen worden, miteinander reagierende Bestandteile voneinander getrennt aufzubewahren und erst direkt vor resp. während des Waschvorgangs zu kombinieren (siehe z.B. WO 2004/053042 ). Die Aufbewahrung kann in separaten Behältern und anschliessender Dosierung aus diesen erfolgen oder - bevorzugt - aus Zwei- oder Mehrkammerflaschen oder Beuteln. Solche Behälter sind bekannt (siehe WO 2004/053042 ).To avoid such problems, it has already been proposed to store mutually reactive components separately and only directly before resp. during the washing process (see eg WO 2004/053042 ). The storage can take place in separate containers and subsequent dosing of these or - preferably - from two- or multi-chamber bottles or bags. Such containers are known (see WO 2004/053042 ).

Als Bleichmittel enthaltende Teilzusammensetzung wird in WO 2004/053042 eine Zusammensetzung empfohlen, welche im wesentlichen aus Wasser und einer organischen Persäure, welche in Wasser gelöst sein kann, besonders bevorzugt aber zumindest teilweise ungelöst in feinteiliger Form vorliegt, vorgeschlagen. Die Teilzusammensetzung soll einen sauren pH-Wert aufweisen und kann gegebenenfalls ein mit der organischen Persäure verträgliches Aniontensid in Mengen bis 50 Gew.-% bezogen auf die Teilzusammensetzung enthalten ( WO 2004/053042 ). Was für Tenside mit der Persäure verträglich sein können wird nicht beschrieben.As a bleach-containing component composition is described in WO 2004/053042 a composition is recommended which consists essentially of water and an organic peracid which may be dissolved in water, more preferably but at least partially undissolved in finely divided form. The partial composition should have an acidic pH and may optionally contain an anionic surfactant compatible with the organic peracid in amounts of up to 50% by weight, based on the partial composition ( WO 2004/053042 ). What surfactants can be compatible with the peracid is not described.

Es wurde nun gefunden, dass die Lagerstabilität und/oder der Beitrag an die Waschleistung eines solchen eine organische Persäure enthaltenden Bleichmittels nicht immer zufriedenstellend ist.It has now been found that the storage stability and / or the contribution to the washing performance of such an organic peracid-containing bleaching agent is not always satisfactory.

Ziel der vorliegenden Erfindung war es deshalb, eine Bleichmittel enthaltende Zusammensetzung bereitzustellen, welche zusammen mit einer Enzyme und vorzugsweise auch Tenside enthaltenden Zusammensetzung ein gutes Waschergebnis ergibt und dies bei guter Lagerstabilität.The aim of the present invention was therefore to provide a bleach-containing composition which, together with an enzyme and preferably also surfactants-containing composition gives a good washing result and this with good storage stability.

Dieses Ziel wurde erreicht durch Bereitstellen eines Flüssigwaschmittels gemäss Anspruch 1, insbesondere eines Flüssigwaschmittels umfassend mindestens eine und bevorzugt eine ein Bleichmittel enthaltende flüssige Bleichkomponente und mindestens eine und bevorzugt eine waschaktive Substanzen enthaltende flüssige Waschkomponente, wobei sich die Bleichkomponente dadurch auszeichnet, dass sie (i) als Bleichmittel eine organische Persäure enthält, insbesondere Phthalimido-peroxohexansäure (PAP), sowie (ii) ein Sulfosuccinat, und gegebenenfalls ein Phosphonat. Weitere Ausführungsformen sind den abhängigen Ansprüchen zu entnehmen.This object has been achieved by providing a liquid detergent according to claim 1, in particular a liquid detergent comprising at least one and preferably a bleach-containing liquid bleach component and at least one and preferably a wash component containing wash-active substances, the bleach component being characterized in that it comprises (i) as bleaching agent contains an organic peracid, in particular phthalimido peroxohexanoic acid (PAP), and (ii) a sulfosuccinate, and optionally a phosphonate. Further embodiments can be found in the dependent claims.

Vorzugsweise liegt die organische Persäure mindestens teilweise ungelöst in Form kleiner Teilchen mit Teilchengrössen von 95 % kleiner 50 µm vor. Speziell bevorzugt liegt die Teilchengrösse von ca. 90 % der Teilchen im Bereich von 5 bis 10 µm. Durch die Verwendung kleiner Teilchen mit möglichst homogener Grössenverteilung wird einerseits deren rasche Auflösung während des Waschvorgangs gewährleistet, andererseits trägt die homogene Grössenverteilung zur Stabilisierung der Grösse und Morphologie der Kristalle bei.Preferably, the organic peracid is at least partially undissolved in the form of small particles with particle sizes of 95% less than 50 microns before. Especially preferred is the particle size of about 90% of the particles in the range of 5 to 10 microns. The use of small particles with as homogeneous as possible a size distribution on the one hand ensures their rapid dissolution during the washing process, on the other hand contributes to the homogeneous size distribution to stabilize the size and morphology of the crystals.

Eine zusätzlich stabilisierende Wirkung wird erzielt, wenn der Suspension ein Sulfosuccinat beigegeben wird. Es wird - ohne an diese Theorie in irgendeiner Form gebunden sein zu wollen - angenommen, dass die Wirkung dieser spezifischen Tensidklasse darauf beruht, dass sie sich an die Oberfläche der suspendierten Teilchen anlagert und damit einerseits ebenfalls deren Grösse stabilisiert, andererseits zu einer gegenseitigen Abstossung der Teilchen führt und damit Agglomeratbildung verhindert.An additional stabilizing effect is achieved when the suspension is added to a sulfosuccinate. It is believed, without wishing to be bound by this theory in any way, that the effect of this specific class of surfactants is based on their being attached to the surface of the suspended particles and thus on the one hand also stabilizes their size, on the other hand leads to a mutual repulsion of the particles and thus prevents agglomeration.

Bevorzugte Sulfosuccinate sind Sulfosuccinate, wie Laureth-sulfosuccinate, di-2-Ethylhexyl-sulfosuccinat, di-iso-Decyl-sulfosuccinat, di-iso-Octyl-sulfosuccinat, Sulfosuccinate aus Fettsäurealkanolaminen und Mischungen solcher Succinate, insbesondere Laureth-sulfosuccinate, speziell bevorzugt Laureth-3-sulfosuccinat. Bevorzugte Sulfosuccinate sind die (di-)NatriumSalze.Preferred sulfosuccinates are sulfosuccinates, such as laureth-sulfosuccinate, di-2-ethylhexyl-sulfosuccinate, di-iso-decyl-sulfosuccinate, di-iso-octyl-sulfosuccinate, sulfosuccinates of fatty acid alkanolamines and mixtures of such succinates, especially laureth-sulfosuccinates, especially preferably laureth -3-sulfosuccinate. Preferred sulfosuccinates are the (di) sodium salts.

Der positive Einfluss auf das Teilchenwachstum, resp. die Verhinderung eines solchen Wachstums, zeigt sich besonders schön, wenn eine erfindungsgemässe Zusammensetzung einem Temperatur-Schaukeltest ausgesetzt wird. Bereits bei Maximaltemperaturen von 40°C, wie sie im Sommer mühelos erreicht werden, zeigt sich ein markanter Stabilitätsgewinn.The positive influence on particle growth, resp. the prevention of such growth, is particularly beautiful when a composition according to the invention is subjected to a temperature swing test. Even at maximum temperatures of 40 ° C, as easily achieved in summer, there is a marked gain in stability.

Einen zusätzlichen stabilisierenden Gewinn sowie eine Verbesserung der Waschleistung erhält man, wenn zusätzlich zum Sulfosuccinat ein Phosphonat beigemischt wird, insbesondere Hydroxyethyl-di-phosphonat (HEDP). Dieses dient als Komplexbildner für Schwermetalliönen, welche die Persäure katalytisch zersetzen können, aber auch für die Härtebildner Ca2+, Mg2+.An additional stabilizing gain as well as an improvement in the washing performance is obtained if, in addition to the sulfosuccinate, a phosphonate is added, in particular hydroxyethyl di-phosphonate (HEDP). This serves as a complexing agent for heavy metal ions, which can catalytically decompose the peracid, but also for the hardness formers Ca 2+ , Mg 2+ .

Zusätzlich kann die Bleichkomponente ein Verdickungsmittel enthalten, z.B. ein Verdickungsmittel ausgewählt aus der Gruppe der Hydrocolloide wie Xanthan oder lösliche Cellulosederivate und Mischungen derselben.In addition, the bleaching component may contain a thickening agent, e.g. a thickening agent selected from the group of hydrocolloids such as xanthan or soluble cellulose derivatives and mixtures thereof.

Die Peroxosäure wird (bezogen auf das Gesamtgewicht der Bleichkomponente) üblicherweise in Mengen von 1-17 Gew.-%, vorzugsweise von 2-7 Gew.-%, speziell bevorzugt von 3-6 Gew.-% eingesetzt, und das Sulfosuccinat üblicherweise in Mengen von 0.1 bis 5 Gew.-%, vorzugsweise 0.25 bis 3 Gew.-%, insbesondere von 0.5 bis 2 Gew.-%. Übliche Mengen an Phosphonat sind von 0.1 bis 2.5 Gew.-%, vorzugsweise 0.3 bis 2 Gew.-% insbesondere von 0.5 bis 1.5 Gew.-%. Das Verdickungsmittel wird in solchen Mengen eingesetzt, dass, gemessen bei 25°C mit einem Brookfield-Viskosimeter mit zylindrischer Spindel, eine Viskosität im Bereich von 300-1500 mPas, bevorzugt 600-1000 mPas resultiert.The peroxy acid is used (based on the total weight of the bleaching component) usually in amounts of 1-17 wt .-%, preferably 2-7 wt .-%, particularly preferably 3-6 wt .-%, and the sulfosuccinate usually in Amounts of 0.1 to 5 wt .-%, preferably 0.25 to 3 wt .-%, in particular from 0.5 to 2 wt .-%. Usual amounts of phosphonate are from 0.1 to 2.5 wt .-%, preferably 0.3 to 2 wt .-%, in particular from 0.5 to 1.5 wt .-%. The thickener is used in such amounts that, measured at 25 ° C with a Brookfield viscometer with a cylindrical spindle, a viscosity in the range of 300-1500 mPas, preferably 600-1000 mPas results.

Der pH-Wert der Bleichkomponente beträgt üblicherweise 1.5 bis 6.5, insbesondere 2.5 bis 4.5.The pH of the bleaching component is usually 1.5 to 6.5, in particular 2.5 to 4.5.

Neben Wasser als üblichem "Lösungsmittel" resp. flüssigem Träger kann die Bleichkomponente auch weitere Lösungsmittel resp. flüssige Träger enthalten, z.B. das bevorzugte Propylenglykol. Übliche Wassergehalte liegen im Bereich von 50 bis 95 Gew.-% und übliche Propylenglykolmengen im Bereich von 0 bis 10 Gew.-%.In addition to water as a common "solvent" resp. liquid carrier, the bleaching component or other solvents resp. liquid carriers, e.g. the preferred propylene glycol. Typical water contents are in the range of 50 to 95 wt .-% and conventional amounts of propylene glycol in the range of 0 to 10 wt .-%.

Daneben kann die Bleichkomponente weitere Stoffe enthalten, wie weitere Tenside, z.B. Na-Alkansulfonat, Aminoxid, Alkylpolyglycosid, Fettalkoholethoxylat und Mischungen derselben.In addition, the bleaching component may contain other substances, such as other surfactants, e.g. Na alkanesulfonate, amine oxide, alkyl polyglycoside, fatty alcohol ethoxylate and mixtures thereof.

Eine Bleichkomponente mit dieser Zusammensetzung eignet sich für die Verwendung in Kombination mit einer beliebigen Waschkomponente, z.B. im Verhältnis 1:1 bis 1:4 (Bleichkomponente:Waschkomponente).A bleaching component with this composition is suitable for use in combination with any washing component, e.g. in the ratio 1: 1 to 1: 4 (bleaching component: washing component).

Eine solche Bleichkomponente ist aber auch hervorragend geeignet für den Einsatz zusammen mit einer speziellen, besonders für tiefe Waschtemperatur geeigneten Waschkomponente.However, such a bleaching component is also outstandingly suitable for use together with a special, especially for low washing temperature suitable washing component.

Diese enthält neben Enzymen und - üblicherweise - anionischen Tensiden, eine spezielle Kombination nicht-ionischer Tenside, nämlich eine Kombination aus mindestens einer mit Polyethylenglykol veresterten Fettsäure und mindestens einem mit Polyethylenglykol veretherten (ethoxylierten) Fettalkohol. Die Anzahl Ethylenoxid-Gruppen im Fettsäureester beträgt üblicherweise 5 bis 15, bevorzugt 8 bis 12. Die Anzahl Ethylenoxid-Gruppen im veretherten Fettalkohl beträgt üblicherweise 3 bis 15, bevorzugt 5 bis 9.This contains in addition to enzymes and - usually - anionic surfactants, a special combination of nonionic surfactants, namely a combination of at least one esterified with polyethylene glycol fatty acid and at least one etherified with polyethylene glycol (ethoxylated) fatty alcohol. The number of ethylene oxide groups in the fatty acid ester is usually 5 to 15, preferably 8 to 12. The number of ethylene oxide groups in the etherified fatty alcohol is usually 3 to 15, preferably 5 to 9.

Überraschenderweise wurde gefunden, dass sich durch den Einsatz dieses Systems ein hoher Anteil an nichtionischen Tensiden erzielen lässt, ohne dass die Waschkomponente beim Einbringen in kaltes Wasser geliert und dadurch die Waschwirkung vermindert wird. Das Verhältnis von Fettsäureester zu ethoxyliertem Fettalkohol beträgt üblicherweise von 1:1 bis 1:4, insbesondere 1:1 bis 1:3, und das Tensidsystem wird üblicherweise in Mengen von 5 bis 70 Gew.-%, vorzugsweise von 15 bis 60 Gew.-%, insbesondere von 20 bis 55 Gew.-% bezogen auf die Waschkomponente eingesetzt.It has surprisingly been found that the use of this system makes it possible to achieve a high proportion of nonionic surfactants without the gelling component gelling when introduced into cold water, thereby reducing the washing action. The ratio of fatty acid ester to ethoxylated fatty alcohol is usually from 1: 1 to 1: 4, in particular 1: 1 to 1: 3, and the surfactant system is usually used in amounts of 5 to 70 wt .-%, preferably from 15 to 60 wt. -%, in particular from 20 to 55 wt .-% based on the washing component used.

Neben diesem speziellen Tensidsystem können weitere nichtionische und/oder ionische und/oder amphotere Tenside vorhanden sein. Bevorzugte Vertreter sind nachstehend aufgeführt.In addition to this particular surfactant system, other nonionic and / or ionic and / or amphoteric surfactants may be present.
