Description
Die Erfindung betrifft ein Waschmittel für empfindliche Textilien. Die Erfindung betrifft auch die Verwendung des Waschmittels sowie ein Verfahren zu seiner Herstellung.The invention relates to a detergent for delicate textiles. The invention also relates to the use of the detergent and to a process for its preparation.
Waschmittel, die auch zur schonenden Reinigung hochempfindlicher Textilien aus Wolle und/oder Seide geeignet sind, sind an sich bekannt. Sie weisen im Allgemeinen einen neutral bis schwach alkalischen pH-Wert auf und enthalten neben anionischen Tensiden, wie Alkylbenzolsulfonat, Fettalkoholsulfat oder Alkylglykolethersulfat vielfach noch nichtionische und/oder kationische Verbindungen. Die nichtionischen Tenside sollen das Reinigungsvermögen steigern, während die kationischen Verbindungen die Weichheit und den Griff der gewaschenen Textilien verbessern sollen. Der Zusatz von weichmachenden kationischen Tensiden führt allerdings bei gleichzeitiger Gegenwart anionischer Tenside zu einem Rückgang an Waschleistung und Produktstabilitat.Detergents which are also suitable for the gentle cleaning of highly sensitive textiles made of wool and / or silk are known per se. They generally have a neutral to slightly alkaline pH and, in addition to anionic surfactants such as alkylbenzenesulfonate, fatty alcohol sulfate or alkyl glycol ether sulfate, often contain nonionic and / or cationic compounds. The nonionic surfactants are said to enhance detergency while the cationic compounds are said to improve the softness and feel of the laundered fabrics. However, the addition of softening cationic surfactants leads to a decrease in washing performance and product stability in the simultaneous presence of anionic surfactants.
Die Reinigungsleistung eines Waschmittels kann durch Bewegung, erhöhte Waschtemperaturen und/oder längerer Kontaktzeit der textilen Flächengebilde mit der (wässrigen) Waschlösung erhöht werden.The cleaning performance of a detergent can be increased by movement, increased washing temperatures and / or longer contact time of the textile fabrics with the (aqueous) washing solution.
Allerdings führen diese Maßnahmen auch zu Beschädigungen an den Fasern, Verlust von Farbe, Verlust der Form und insbesondere zum Einlaufen der textilen Flächengebilde.However, these measures also lead to damage to the fibers, loss of color, loss of shape and in particular to the shrinkage of the textile fabrics.
Insbesondere textile Flächengebilde aus Wolle verfilzen mit der Zeit und laufen stark ein, wenn sie einem Wasser-basierten Waschverfahren, insbesondere in einer Haushaltswaschmaschine, unterworfen werden. Die unbeabsichtigte Dimensionsänderung (Einlaufen und/oder Formverlust) der textilen Flächengebilde bei Mechanik-, Wasser- und/oder Wärmeeinfluss wird auch als Schrumpfen bezeichnet. Hierbei werden auch die haptischen Eigenschaften des Textils verändert.In particular, textile fabrics of wool become entangled with time and become heavily impacted when subjected to a water-based washing process, particularly in a household washing machine. The unintended dimensional change (shrinkage and / or loss of shape) of the textile fabrics under the influence of mechanics, water and / or heat is also referred to as shrinkage. This also changes the haptic properties of the textile.
Außerdem führt wiederholtes Waschen dazu, dass textile Flächengebilde ihre Elastizität verlieren. Dies führt dazu, dass die Textilien nach einer Dehnung nicht mehr vollständig in ihre ursprüngliche Form zurückkehren, sondern eine Restdehnung verbleibt.In addition, repeated washing causes fabrics to lose their elasticity. As a result, the textiles no longer completely return to their original shape after being stretched, but a residual elongation remains.
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, ein Waschmittel bereitzustellen, welches den damit behandelten Textilien Weichheit verleiht sowie deren Schrumpfneigung reduziert und/oder deren Elastizität verbessert.It is therefore an object of the present invention to provide a detergent which imparts softness to the textiles treated therewith and reduces their shrinkage tendency and / or improves their elasticity.
Diese Aufgabe wird gelöst durch ein Waschmittel, enthaltend
- a) 5 bis 15 Gew.-% anionisches Tensid und
- b) 0,01 bis 1 Gew.-% eines hydrophob-modifizierten, kationischen Polymers, das als Grundgerüst ein Polysaccharid ausgewählt aus der Gruppe umfassend Cellulose und Cellulosederivate enthält,

In einer besonders bevorzugten Ausführungsform umfasst das besagte hydrophob-modifizierte, kationische Polymer eine mit Trimethylammoniumhydroxypropylgruppen und C8-24-Alkyldimethylammoniumhydroxypropylgruppen substituierte Hydroxyethylcellulose. Es hat sich als vorteilhaft gezeigt, dass die Einarbeitung einer derart substituierten Cellulose in flüssige Waschmittel zu keinem unerwünscht hohen Anstieg der Viskosität führt, wie es teilweise bei anderen kationisch modifizierten Cellulose(derivate)n zu beobachten ist.In a particularly preferred embodiment, said hydrophobically-modified cationic polymer comprises a hydroxyethylcellulose substituted with trimethylammoniumhydroxypropyl groups and C 8-24 -alkyldimethylammoniumhydroxypropyl groups.

The anionic surfactant used is preferably sulfonates, sulfates, soaps, alkyl phosphates, anionic silicone surfactants and mixtures thereof.
Als Tenside vom Sulfonat-Typ kommen dabei vorzugsweise C9-13-Alkylbenzolsulfonate und Olefinsulfonate in Betracht Geeignet sind auch C12-18-Alkansulfonate und die Ester von α-Sulfofettsäuren (Estersulfonate), zum Beispiel die α-sulfonierten Methylester der hydrierten Kokos-, Palmkem- oder Talgfettsäuren.Suitable surfactants of the sulfonate type are preferably C 9-13 -alkylbenzenesulfonates and olefinsulfonates.

Aus waschtechnischem Interesse sind die C12-C16-Alkylsulfate und C12-C16-Alkylsulfate sowie C14-C15-Alkylsulfate bevorzugt. Auch 2,3-Alkylsulfate sind geeignete anionische Tenside.Alk (en) ylsulfates are the alkali metal salts and in particular the sodium salts of the sulfuric monoesters of C 12 -C 16 fatty alcohols, for example coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C 10 -C 20 oxo alcohols and those half-esters of secondary alcohols of these chain lengths are preferred. Of washing technology interest, the C 12 -C 16 alkyl sulfates and C 12 -C 16 alkyl sulfates and C 14 -C 15 alkyl sulfates are preferred. 2,3-alkyl sulfates are also suitable anionic surfactants.

Particularly preferred is a combination of C 9-13 alkylbenzenesulfonate, fatty acid soap and ethoxylated fatty alcohol sulfate has been found.
Der Gehalt eines Waschmittels an anionischen Tensiden beträgt 5 bis 15 Gew.-% und vorzugsweise 7 bis 12 Gew.-%, jeweils bezogen auf das gesamte Waschmittel. Es hat sich überraschenderweise gezeigt, dass Waschmittel, die weniger als 5 Gew.-% oder mehr als 15 Gew.-% anionisches Tensid enthalten, deutlich instabiler sind als die erfindungsgemäßen Waschmittel. Entsprechend zeigen diese Waschmittel auch eine deutlich schlechtere Reinigungsleistung.The content of a detergent to anionic surfactants is 5 to 15 wt .-% and preferably 7 to 12 wt .-%, each based on the total detergent. It has surprisingly been found that detergents which contain less than 5% by weight or more than 15% by weight of anionic surfactant are significantly more unstable than the detergents according to the invention. Accordingly, these detergents also show a significantly poorer cleaning performance.
Neben den/dem anionischen Tensid(en) können die Waschmittel weitere Tenside enthalten, wobei aus anwendungstechnischer Sicht Mischungen aus anionischen und nichtionischen Tensiden bevorzugt sind. Der Gesamttensidgehalt eines Waschmittels liegt vorzugsweise unterhalb von 25 Gew.-% und besonders bevorzugt unterhalb von 20 Gew.-%, bezogen auf das gesamte Waschmittel.In addition to the anionic surfactant (s), the detergents may contain further surfactants, with mixtures of anionic and nonionic surfactants being preferred from an application point of view.

Insbesondere sind jedoch Alkoholethoxylate mit linearen Resten aus Alkoholen nativen Ursprungs mit 12 bis 18 C-Atomen, zum Beispiel aus Kokos-, Palm-, Talgfett- oder Oleylalkohol, und durchschnittlich 2 bis 8 EO pro Mol Alkohol bevorzugt. Zu den bevorzugten ethoxylierten Alkoholen gehören beispielsweise C12-14-Alkohole mit 3 EO, 4 EO oder 7 EO, C9-11-Alkohol mit 7 EO, C13-15-Alkohole mit 3 EO, 5 EO, 7 EO oder 8 EO, C12-18-Alkohole mit 3 EO, 5 EO oder 7 EO und Mischungen aus diesen, wie Mischungen aus C12-14-Alkohol mit 3 EO und C12-18-Alkohol mit 7 EO. Die angegebenen Ethoxylierungsgrade stellen statistische Mittelwerte dar, die für ein spezielles Produkt eine ganze oder eine gebrochene Zahl sein können. Bevorzugte Alkoholethoxylate weisen eine eingeengte Homologenverteilung auf (narrow range ethoxylates, NRE). Zusätzlich zu diesen nichtionischen Tensiden können auch Fettalkohole mit mehr als 12 EO eingesetzt werden. Beispiele hierfür sind Talgfettalkohol mit 14 EO, 25 EO, 30 EO oder 40 EO. Auch nichtionische Tenside, die EO- und PO-Gruppen zusammen im Molekül enthalten, sind erfindungsgemäß einsetzbar. Geeignet sind ferner auch eine Mischung aus einem (stärker) verzweigten ethoxylierten Fettalkohol und einem unverzweigten ethoxylierten Fettalkohol, wie beispielsweise eine Mischung aus einem C16-18-Fettalkohol mit 7 EO und 2-Propylheptanol mit 7 EO. Insbesondere bevorzugt enthält das Waschmittel einen C12-18-Fettalkohol mit 7 EO oder einen C13-15-Oxoalkohol mit 7 EO als nichtionisches Tensid.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 linear and methyl-branched radicals in the mixture can contain, as they are usually present in Oxoalkoholresten. In particular, however, are alcohol ethoxylates having linear radicals of alcohols of native origin having 12 to 18 carbon atoms, for example coconut, palm, tallow or oleyl alcohol, and on average 2 to 8 EO per Mol of alcohol is preferred. The preferred ethoxylated alcohols include, for example, C 12-14 alcohols with 3 EO, 4 EO or 7 EO, C 9-11 alcohols with 7 EO, C 13-15 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C 12-18 -alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C 12-14 -alcohol with 3 EO and C 12-18 -alcohol with 7 EO. The degrees of ethoxylation given represent statistical means which, for a particular product, may be an integer or a fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples include tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO. Nonionic surfactants containing EO and PO groups together in the molecule can also be used according to the invention. Also suitable are also a mixture of a (more) branched ethoxylated fatty alcohol and an unbranched ethoxylated fatty alcohol, such as a mixture of a C 16-18 fatty alcohol with 7 EO and 2-propylheptanol with 7 EO. In particular, the detergent preferably contains a C 12-18 fatty alcohol with 7 EO or a C 13-15 oxo alcohol with 7 EO as nonionic surfactant.
Der Gehalt an nichtionischen Tensiden beträgt in dem Waschmittel bevorzugt 1 bis 17 Gew.-%, vorzugsweise 2 bis 12 Gew.-% und insbesondere 3 bis 10 Gew.-%, jeweils bezogen auf das gesamte Waschmittel.The content of nonionic surfactants is in the detergent preferably 1 to 17 wt .-%, preferably 2 to 12 wt .-% and in particular 3 to 10 wt .-%, each based on the total detergent.
In einer bevorzugten Ausführungsform enthält das Waschmittel neben dem anionischen Tensid und dem hydrophob-modifizierten, kationischen Polymer 0,02 bis 5 Gew.-%, bezogen auf das gesamte Waschmittel, eines Polyalkylenglycols. Als Polyalkylenglycole können beispielsweise Polyethylenglycole, Polypropylenglycole oder Mischungen aus Polyethylenglycolen und Polypropylenglycolen eingesetzt werden.In a preferred embodiment, in addition to the anionic surfactant and the hydrophobically-modified cationic polymer, the detergent contains from 0.02 to 5% by weight, based on the total detergent, of a polyalkylene glycol. Polyalkylene glycols which can be used are, for example, polyethylene glycols, polypropylene glycols or mixtures of polyethylene glycols and polypropylene glycols.
Es hat sich gezeigt, dass bevorzugt Polyethylenglycole mit einer mittleren Molekülmasse zwischen 200 und 400 eingesetzt werden können. Oftmals lassen sich hydrophob-modifizierte, kationische Polymere, insbesondere hydrophob-modifizierte, kationische Celluloseverbindungen nur schwer und nur in geringen Konzentrationen in Wasser lösen. Dies führt dazu, dass diese Polymere nur schwer, stabil in wässrige Waschmittel eingearbeitet werden können. Überraschenderweise hat sich gezeigt, dass ein Gemisch aus dem hydrophob-modifizierten, kationischen Polymer und einem Polyethylenglycol mit einer mittleren Molekülmasse zwischen 200 und 400 zu einem fließfähigen, gut in ein wässriges Waschmittel einarbeitbarem Slurry führt. Zusätzlich weist das erhaltene wässrige Waschmittel eine erhöhte Stabilität auf.It has been found that preferably polyethylene glycols having an average molecular weight between 200 and 400 can be used. Often, hydrophobic-modified, cationic polymers, in particular hydrophobically-modified, cationic cellulose compounds can be dissolved only with difficulty and only in low concentrations in water. As a result, these polymers are difficult, stable to incorporate into aqueous detergents. Surprisingly, it has been found that a mixture of the hydrophobically-modified, cationic polymer and a polyethylene glycol having an average molecular weight between 200 and 400 leads to a flowable slurry which can readily be incorporated into an aqueous detergent. In addition, the resulting aqueous detergent has an increased stability.

Die Herstellung von flüssigen Waschmitteln erfolgt mittels üblicher und bekannter Methoden und Verfahren in dem beispielsweise die Bestandteile einfach in Rührkesseln vermischt werden, wobei Wasser, nichtwässrige Lösungsmittel und Tenside, zweckmäßigerweise vorgelegt werden. Anschließend wird, falls vorhanden, die Fettsäure zugegeben und es erfolgt die Verseifung des Fettsäureanteils sowie die Neutralisation der anionischen Tenside, welche in der Säureform eingesetzt werden. Danach werden die weiteren Bestandteile mit Ausnahme des hydrophob-modifizierten, kationischen Polymers portionsweise hinzugefügt. Im letzten Schritt wird das hydrophob-modifizierte, kationische Polymer entweder in Form einer wässrigen Lösung mit einem pH-Wert von 8,0 ± 0,2 oder in Form eines Slurries mit Polyalkylenglycol zugegeben.The preparation of liquid detergents is carried out by means of customary and known methods and processes in which, for example, the constituents are simply mixed in stirred kettles, whereby water, non-aqueous solvents and surfactants are expediently initially introduced. Subsequently, if present, the fatty acid is added and the saponification of the fatty acid portion and the neutralization of the anionic surfactants, which are used in the acid form. Thereafter, the other ingredients except the hydrophobically-modified cationic polymer are added in portions. In the last step, the hydrophobically-modified cationic polymer is added either in the form of an aqueous solution with a pH of 8.0 ± 0.2 or in the form of a slurries with polyalkylene glycol.
In Tabelle 1 sind die Zusammensetzungen zweier erfindungsgemäßer Waschmittel E1 und E2 sowie von zwei Vergleichbeispielen V1 und V2 gezeigt (Angaben in Gew.-% Aktivstoff).
** Polyethylenglycol mit einer mittleren Molekülmasse von 400
** Polyethylene glycol with an average molecular weight of 400
Die erfindungsgemäßen Waschmittel E1 und E2 waren über mehrere Wochen lagerstabil und zeigten keinerlei unerwünschte Veränderungen. Zur Bestimmung der Lagerstabilität wurden Proben des Waschmittels in elektronisch gesteuerten Wärmekammern bei unterschiedlichen Temperaturen (0 °C, 23 °C und 40 °) über mehrere Wochen (bis 12 Wochen) gelagert. In diesem Zeitraum erfolgten visuelle, physikalische und olfaktorische Beurteilungen des Waschmittels.Detergents E1 and E2 according to the invention were stable on storage for several weeks and did not show any undesired changes. To determine storage stability, samples of the detergent were stored in electronically controlled heating chambers at different temperatures (0 ° C, 23 ° C and 40 °) for several weeks (up to 12 weeks). During this period, visual, physical and olfactory assessments of the detergent were made.
Außerdem wurden waschtechnische Untersuchungen mit den Waschmitteln E1, E2, V1 und V2 durchgeführt.In addition, washing tests were carried out with the detergents E1, E2, V1 and V2.
Zur Beurteilung der Weichheit wurden textile Flächengebilde aus Seide drei Mal bei 40 °C in einer Haushaltswaschmaschine (Miele) mit jeweils 93 g der Waschmittel E1 oder V1 gewaschen und hängend getrocknet. Anschließend wurde die den textilen Flächengebilden vermittelte Weichheit durch 30 Testpersonen verglichen. 22 Testpersonen beurteilten die mit E1 gewaschenen textilen Flächengebilde als weicher, während 4 Testpersonen keinen Unterschied in der Weichheit der mit E1 und V1 behandelten textilen Flächengebilde sahen.To evaluate the softness, silk fabrics were washed three times at 40 ° C in a household washing machine (Miele) with 93 g each of the detergent E1 or V1 and dried hanging. Subsequently, the softness mediated to the fabrics was compared by 30 test persons. Twenty-two subjects rated the textiles washed with E1 Sheets were softer, while 4 subjects did not see any difference in the softness of the E1 and V1 treated fabrics.
Zur Beurteilung des Schrumpfes wurden Mehrfachwäschen von textilen Flächengebilden aus Wolle drei Mal bei 40 °C mit jeweils 93 g des Waschmittels E1 oder einem Esterquat-haltigen Wollwaschmittel (der Tensidblock umfasste 13 Gew.-% nichtionische Tenside, 0,5 Gew.-% anionische Tenside und 2,5 Gew.-% Esterquat) mit dem Wollprogramm einer Haushaltswaschmaschine (Miele) gewaschen und hängend getrocknet. Anschließend wurde das Ausmaß des Schrumpfes bestimmt.To evaluate the shrinkage, multiple washes of textile fabrics of wool were made three times at 40 ° C with 93 grams each of detergent E1 or an ester quat-containing wool detergent (the surfactant block comprised 13 weight percent nonionic surfactants, 0.5 weight percent anionic Surfactants and 2.5 wt .-% Esterquat) with the wool program of a household washing machine (Miele) washed and dried hanging. Subsequently, the extent of shrinkage was determined.
Während die mit E1 gewaschenen textilen Flächengebilde aus Wolle 95 % ihrer Originalgröße aufwiesen, wiesen die textilen Flächengebilde die mit dem Esterquat-basierten Wollwaschmittel gewaschen wurden, nur noch 92 % ihrer Originalgröße auf.While the textile fabrics washed with E1 had 95% of their original size, the fabrics washed with the esterquat-based wool detergent only had 92% of their original size.
Ferner wurde auch die Restdehnung gemäß DIN 53 835, Teil 13 untersucht.Furthermore, the residual strain according to DIN 53 835, Part 13 was examined.
Zur Beurteilung der Restdehnung wurden textile Flächengebilde aus 100% Seide oder aus 70% Wolle und 30 % Seide zusammen mit einer Ballastbeladung aus Polyester und Baumwolle (Gesamtbeladung: 1,5 kg) zunächst acht Mal bei 30 °C in einer Haushaltswaschmaschine (Miele W 527) mit jeweils 90 ml des Waschmittels V2 gewaschen.To evaluate the residual elongation, textile fabrics of 100% silk or 70% wool and 30% silk together with a ballast loading of polyester and cotton (total load: 1.5 kg) were first eight times at 30 ° C in a household washing machine (Miele W 527 ) Each washed with 90 ml of the detergent V2.
Anschließend wurden die textilen Flächengebilde in zwei Gruppen aufgeteilt. Die erste Gruppe wurde sechs Mal mit jeweils 90 ml des Waschmittels V2 und die zweite Gruppe wurde sechs Mal mit jeweils 90 ml des Waschmittels E2 gewaschen. In beiden Fällen war zusätzlich in jedem Waschgang jeweils die gleiche Menge an Schmutzbeladungstücher SBL-2004 von der WFK Testgewebe GmbH vorhanden. Nach hängender Trocknung der textilen Flächengebilde wurde die Restdehnung gemäß DIN 53 835, Teil 13 bestimmt.Subsequently, the fabrics were divided into two groups. The first group was washed six times with 90 ml each of the detergent V2 and the second group was washed six times with 90 ml each of the detergent E2. In both cases, the same amount of SBL-2004 dirt load wipes from WFK Testgewebe GmbH was additionally present in each wash cycle. After hanging drying of the textile fabrics, the residual elongation was determined according to DIN 53 835, Part 13.
In Tabelle 2 ist die Restdehnung (in %) der wie oben beschrieben behandelten textilen Flächengebilde als arithmetisches Mittel von 10 Messungen mit Standardabweichungen angegeben.
Die Daten in Tabelle 2 zeigen deutlich, dass durch Behandlung mit dem erfindungsgemäßen Waschmittel E2 die Elastizität der damit behandelten textilen Flächengebilde verbessert werden kann. Insbesondere zeigen die Daten deutlich, dass die Restdehnung von textilen Flächengebilden aus Wolle und/oder Seide verringert werden kann.The data in Table 2 clearly show that the elasticity of the textile fabrics treated therewith can be improved by treatment with the inventive detergent E2. In particular, the data clearly show that the residual elongation of textile fabrics of wool and / or silk can be reduced.
Zusätzlich zeigten die mit E2 gewaschenen textilen Flächengebilde beim Waschen eine geringere Schrumpfneigung als die textilen Flächengebilde, die mit dem Waschmittel V2 behandelt wurden. Außerdem vermittelte das Waschmittel E2 den damit behandelten textilen Flächengebilden einen angenehmen Weichgriff.In addition, the fabrics washed with E2 showed a lower tendency to shrink during washing than the fabrics treated with the detergent V2. In addition, the detergent E2 imparted to the textile fabrics treated therewith a pleasant soft feel.
