Aufgabe der vorliegenden Erfindung ist die Entwicklung eines Spezialwaschmittels, welches auf die eingangs genannten spezifischen Probleme und Bedürfnisse bei der Verwendung von Spezialfasern zugeschnitten ist. Als Formulierungsbasis dient ein Feinwaschmittel, kein Vollwaschmittel. Object of the present invention is the development of a special detergent, which is tailored to the specific problems and needs mentioned in the use of special fibers mentioned above. The formulation is based on a mild detergent, not a heavy duty detergent.
Die erfindungsgemäße Aufgabe wird erfüllt durch eine vorzugsweise flüssige Formulierung für ein Spezialwaschmittel, umfassend ein Tensidsystem, ein Enzymsystem, gegebenenfalls zusätzliche Wirkstoffe/ Additive, sowie gegebenenfalls ein oder mehrere Farb-und/oder Duftstoffe. The object of the invention is fulfilled by a preferably liquid formulation for a special detergent, comprising a surfactant system, an enzyme system, optionally additional active ingredients / additives, and optionally one or more colorants and / or fragrances.
Demgemäß stellt die vorliegende Erfindung ein Spezialwaschmittel zur Verfügung, umfassend eine Formulierung mit einem Tensidsystem und einem Enzymsystem, dadurch gekennzeichnet, dass das Enzymsystem zumindest eine Protease und zumindest eine Pektinase oder Pektat-Lyase umfasst, und dass das Waschmittel im Tensidsystem auf Massebasis mehr nichtionische Tenside als anionische Tenside aufweist. Accordingly, the present invention provides a special detergent composition comprising a formulation having a surfactant system and an enzyme system, characterized in that the enzyme system comprises at least one protease and at least one pectinase or pectate lyase, and the detergent in the surfactant system comprises more nonionic surfactants as anionic surfactants.
Es hat sich im Zuge der vorliegenden Erfindung gezeigt, dass das erfindungsgemäße It has been found in the course of the present invention that the inventive
Spezialwaschmittel überraschenderweise eine besonders gute Reinigungswirkung hat. Die erfindungsgemäße Kombination des Tensidsystems enthaltend mehr nichtionische als anionische Tensiden mit dem Enzymsystem enthaltend sowohl Pektinase / Pektat Lyase als auch Protease, hat sich besonders vorteilhaft für die Entfernung von Flecken erwiesen, insbesondere von Lebensmittelflecken, beispielsweise von Obst. Special detergent surprisingly has a particularly good cleaning effect. The inventive combination of the surfactant system containing more nonionic than anionic surfactants with the enzyme system containing both pectinase / pectate lyase and protease has have proven particularly advantageous for the removal of stains, especially food stains, such as fruit.
Weitere Vorteile des erfindungsgemäßen Spezialwaschmittels sind eine besonders gute Schonung und damit lange Haltbarkeit der bioziden Ausrüstung (Zn-Pyrithion), ein geringes Further advantages of the special detergent according to the invention are a particularly good protection and thus long durability of biocidal equipment (Zn-pyrithione), a low
Verklumpungsrisiko von Polyester- Kugeln und darüber hinaus auch noch ein geringes Allergierisiko (da Laurylsulfat und Alkylbenzolsulfonate vermieden werden können). Clogging risk of polyester bullets and also a low risk of allergy (since lauryl sulfate and alkylbenzenesulfonates can be avoided).
In einer bevorzugten Ausführungsform enthält das erfindungsgemäße Spezialwaschmittel zwischen 1 und 4 Gew.-% Seife. Dadurch wird eine zu starke Schaumbildung vermieden und Rückstände können gut ausgewaschen werden. In a preferred embodiment, the special detergent according to the invention contains between 1 and 4 wt .-% soap. As a result, excessive foaming is avoided and residues can be washed out well.
Wenn hier und im Folgenden Angaben zu Gew.-% gemacht werden, sind - sofern nichts anderes angegeben wird - darunter die Prozentanteile der gesamten Zusammensetzung, im vorliegenden Fall des erfindungsgemäßen Spezialwaschmittels, zu verstehen Unless stated otherwise, percentages of the total composition, in this case the special detergent according to the invention, are to be understood as meaning here and below information on% by weight
Es hat sich als besonders vorteilhaft erwiesen, wenn das erfindungsgemäße Spezialwaschmittel in wässriger Lösung, z.B. während eines Waschvorgangs, nur zu einem leicht basischen pH-Wert führt. Unter anderem wird dadurch eine besonders effiziente Fleckenentfernung sowie eine gute It has proven to be particularly advantageous if the special detergent according to the invention in aqueous solution, e.g. during a wash, only to a slightly basic pH results. Among other things, this is a particularly efficient stain removal and a good
Haltbarkeit der bioziden Ausrüstung gewährleistet. In einer bevorzugten Ausführungsform weist das Spezialwaschmittel in wässriger Lösung daher einen pH-Wert von unter 8,0, vorzugsweise einen pH-Wert von 7,5 auf. Durability of biocidal equipment ensured. In a preferred embodiment, the special detergent in aqueous solution therefore has a pH of less than 8.0, preferably a pH of 7.5.
Der pH-Wert in wässriger Lösung wird im Zusammenhang mit der vorliegenden Erfindung als pH- Wert einer üblichen Verdünnung des Waschmittels in Wasser während des Waschvorgangs verstanden, insbesondere als der pH-Wert von 50 mL Waschmittel gelöst in 10 L Wasser. In the context of the present invention, the pH in aqueous solution is understood as the pH of a customary dilution of the detergent in water during the washing process, in particular as the pH of 50 ml of detergent dissolved in 10 l of water.
Zweckmäßigerweise liegt das Spezialwaschmittel als flüssige Formulierung vor. Conveniently, the special detergent is present as a liquid formulation.
In einer bevorzugten Ausführungsform enthält das Spezialwaschmittel gemäß der Erfindung kein Laurylsulfat. In einer weiteren bevorzugten Ausführungsform enthält das Spezialwaschmittel keine Alkylbenzolsulfonate. Es hat sich gezeigt, dass eine gute Reinigungsleistung überraschenderweise auch ohne Laurylsulfat und ohne Alkylbenzolsulfonate erreicht wird. Ein wesentlicher Vorteil der Abwesenheit dieser Stoffe im erfindungsgemäßen Spezialwaschmittel ist ein geringeres In a preferred embodiment, the special detergent according to the invention contains no lauryl sulfate. In a further preferred embodiment, the special detergent contains no alkylbenzenesulfonates. It has been found that a good cleaning performance is surprisingly achieved even without lauryl sulfate and without alkylbenzenesulfonates. A significant advantage of the absence of these substances in the special detergent according to the invention is a lower
Allergierisiko. Risk of allergy.
Wesentlich für die vorliegende Erfindung ist es, dass das Spezialwaschmittel auf Massebasis mehr nichtionische Tenside als anionische Tenside aufweist. Im Rahmen der vorliegenden Erfindung bezieht sich das angegebene Masseverhältnis dabei lediglich auf das Verhältnis von nichtionischen zu anionischen Tensiden, zusätzlich vorhandene Seifen werden bei der Berechnung, ob mehr nichtionische Tenside als anionische Tenside vorliegen, nicht miteinbezogen. Essential for the present invention is that the special detergent on a mass basis more nonionic surfactants than anionic surfactants. In the context of the present invention, the stated mass ratio refers only to the ratio of nonionic to anionic surfactants, additional soaps are not included in the calculation of whether more nonionic surfactants are present as anionic surfactants.
In einer besonders bevorzugten Ausführungsform enthält das Spezialwaschmittel zwischen 5 und 12 Gew.-% anionische Tenside. Als besonders geeignet als anionische Tenside haben sich In a particularly preferred embodiment, the special detergent contains between 5 and 12 wt .-% of anionic surfactants. Particularly suitable as anionic surfactants have
Fettalkoholethersulfate erwiesen. Fatty alcohol ether sulfates proved.
In einer weiteren besonders bevorzugten Ausführungsform enthält das Spezialwaschmittel zwischen 6 und 15 Gew.-% nichtionische Tenside. Als nichtionische Tenside sind insbesondere ethoxylierte Alkohole bevorzugt. Diese besonders bevorzugten Ausführungsformen erlauben in Kombination mit dem erfindungsgemäßen Enzymsystem eine besonders gute Reinigungswirkung. In a further particularly preferred embodiment, the special detergent contains between 6 and 15% by weight of nonionic surfactants. Particularly preferred nonionic surfactants are ethoxylated alcohols. These particularly preferred embodiments, in combination with the enzyme system according to the invention, allow a particularly good cleaning action.
Überraschenderweise hat sich gezeigt, dass als Waschmittelbasis / Tensidsystem besonders die Verwendung von nichtionischen Tensiden als Hauptkomponente, Ethersulfate als anionische Tenside, die Vermeidung von Alklybenzolsulfonate oder Laurylsulfate sowie die Verwendung von Seife als dritte Tensidkomponente geeignet ist. Als Enzymsystem hat sich als besonders geeignet ein für die speziellen Anforderungen optimiertes Multi-Enzymsystem gezeigt, überraschenderweise können Enzyme zum Teil Funktionen übernehmen, die sonst nur von Bleichmitteln erzielt werden. Vorzugsweise erfolgt die Wahl von Enzymtypen, die ihr Optimum bei 40 °C bis 60 °C haben. Surprisingly, it has been found that the detergent base / surfactant system particularly suitable is the use of nonionic surfactants as the main component, ether sulfates as anionic surfactants, the avoidance of alkylbenzenesulfonates or lauryl sulfates and the use of soap as the third surfactant component. As an enzyme system, a multi-enzyme system optimized for the specific requirements has proven to be particularly suitable. Surprisingly, enzymes can sometimes perform functions that would otherwise only be achieved by bleaching agents. Preferably, the choice of enzyme types that have their optimum at 40 ° C to 60 ° C.
Als zusätzliche Wirkstoffe/Additive haben sich im Stand der Technik an sich bekannte Wirkstoffe als günstig erwiesen, davon als besondere Kombination: As additional active ingredients / additives known per se in the prior art have proven to be favorable, of which as a special combination:
• Soil Release Polymer • Soil release polymer
o Leichter Schmutzabweisungseffekt o Light dirt repellent effect
o Bessere Unterstützung der Waschwirkung bei öligen Flecken o Better support of the washing effect on oily stains
• Vergrauungsinhibitor • Grayness inhibitor
• Farbübertragungsinhibitor / Verhinderung der Wiederablagerung von gelöstem Schmutz • Color transfer inhibitor / Prevention of redeposition of dissolved dirt
• Komplexbildner zur zusätzlichen Bindung von Wasserhärte und Metallionen. • complexing agent for additional bonding of water hardness and metal ions.
Als Farbstoff sollte Blau als Synonym für„Frische“ /„frische Brise" gewählt werden. Ebenso Duftstoffe, auch hier erfolgt die Auswahl des bestmöglichen„frisch" bzw.„hygienisch frisch"As a dye, blue should be chosen as a synonym for "freshness" / "fresh breeze." Likewise fragrances, here too, the selection of the best possible "fresh" or "hygienic fresh"
Duftes durch den Fachmann aus an sich im Stand der Technik bekannten Duftstoffe. Fragrance by the skilled person from per se known in the art fragrances.
Erfindungsgemäß wird als Waschmittelgrundlage/Tensidsystem ein System vorgeschlagen, welches auf Massebasis mehr nichtionische Tenside als anionische Tenside aufweist, bei welchem als anionische Tenside bevorzugt Fettalkoholethersulfate zum Einsatz kommen, welches System im Vergleich zu herkömmlichen Feinwaschmitteln nur eine geringe Menge von Seife zur Schaumkontrolle aufweist, ohne Laurylsulfat oder Alkylbenzolsulfonate auskommt und in wässriger Lösung einen nur leicht basischen pH-Wert aufweist, etwa im Bereich von unter 8,0, vorzugsweise um 7,5. In accordance with the invention, the detergent base / surfactant system proposed is a system which has more nonionic surfactants than anionic surfactants on a mass basis, in which fatty alcohol ether sulfates are preferably used as anionic surfactants, which system uses only a small amount of soap compared to conventional mild detergents Has foam control, does not require lauryl sulfate or alkylbenzenesulfonates and in aqueous solution has a slightly basic pH, for example in the range of less than 8.0, preferably by 7.5.
Vorteilhaft bei der Verwendung des erfindungsgemäßen Tensidsystems für Spezialwaschmittel gegenüber Feinwaschmittel oder Sportwaschmittel vom Handel (Bsp. Perwoll für Wolle und Feines / Perwoll Sport ActiveCare) ist, dass beispielsweise die beiden genannten Perwoll Produkte Advantageous in the use of the surfactant system according to the invention for special detergents compared to mild detergents or sports detergents from the trade (eg Perwoll for wool and fine / Perwoll Sport ActiveCare) is that, for example, the two mentioned Perwoll products
Laurylsulfat oder Alkylbenzolsulfonate enthalten, welche erfindungsgemäß wegen höherem Allergierisiko vermieden werden können. Contain lauryl sulfate or alkyl benzene sulfonates, which can be avoided according to the invention for higher risk of allergy.
Auch kommt es bei handelsüblichen Wollwaschmittel zu einer starken Schaumbildung und dadurch zu einer schlechten Auswaschung und dem Risiko von Rückständen. Also, it comes with commercial wool detergents to a strong foaming and thus to a bad leaching and the risk of residues.
Das erfindungsgemäße Spezialwaschmittel ist deshalb nur auf geringe bis mittelstarke The special detergent according to the invention is therefore only low to medium strength
Schaumbildung ausgerichtet. Foaming aligned.
Weiters enthalten beispielsweise Sportwaschmittel Stoffe, die auf Fasern aufziehen können (Quats), wodurch es zu dem Risiko einer negativen Wechselwirkung mit der Zn-Pyrethion Furthermore, for example, sports detergents contain substances that can be absorbed by fibers (quats), which leads to the risk of a negative interaction with the Zn-pyrethion
Ausrüstung der Spezialfasern kommt. Equipment of special fibers comes.
Das erfindungsgemäße Spezialwaschmittel weist weiters ein komplexes Enzymsystem für spezifische Schmutz- und Fleckentfernung auf, umfassend Protease gegen Proteine, Amylase gegen Stärke, Lipase gegen Fett, Mannanase gegen„Mannan“ Flecken sowie Pektat Lyase / Pektinase gegen pektinhaltige Flecken. The special detergent according to the invention further has a complex enzyme system for specific soil and stain removal, comprising protease against proteins, amylase against starch, lipase against fat, mannanase against "mannan" stains and pectate lyase / pectinase against pectin-containing stains.
Dabei hat sich gezeigt, dass Feinwaschmittel oder Sportwaschmittel vom Handel (Bsp. Perwoll für Wolle und Feines / Perwoll Sport ActiveCare), die auch für Wolle geeignet sind, keine Proteasen enthalten, da Wolle durch Proteasen evtl, angegriffen würde. Für die vollständige Reinigung von Bettwäsche ist jedoch wichtig, dass im oben genannten Enzymsystems bei Verwendung im erfindungsgemäßen Spezialwaschmittel Proteasen vorhanden sind. It has been shown that mild detergents or sports detergents from the trade (eg Perwoll for wool and fine / Perwoll Sport ActiveCare), which are also suitable for wool, contain no proteases, as possibly by wool proteases, would be attacked. For the complete cleaning of bed linen, however, it is important that proteases are present in the above-mentioned enzyme system when used in the special detergent according to the invention.
Fein- und Sportwaschmittel enthalten darüber hinaus in der Regel keine Pektinasen, diese sind dagegen häufig in Colorwaschmitteln zu finden, wo mit farbigen Flecken auf der zu waschenden Wäsche zu rechnen ist, aber kein Bleichmittel verwendet wird. Der erfindungsgemäß vorgesehene Einsatz von Pektinase im Enzymsystem ist eine sinnvolle Ergänzung, insbesondere bei der bevorzugten Verwendung eines bleichfreien Systems. In addition, fine and sports detergents generally contain no pectinases, however, these are often found in color detergents, where to be expected with colored stains on the laundry to be washed, but no bleach is used. The use according to the invention of pectinase in the enzyme system is a useful supplement, in particular in the preferred use of a bleach-free system.
Das erfindungsgemäß vorgesehene Enzymsystem im Spezialwaschmittel kombiniert die optimal möglichen Enzyme aus Fein- und Colorwaschmitteln. Aus der folgenden Tabelle ist die Formulierung für ein besonders bevorzugtes erfindungsgemäßes Spezialwaschmittel ersichtlich (Spalte„Aktivgehalt“), sowie andere Formulierungen, die unter den Gegenstand der vorliegenden Erfindung fallen (Spalte„Rahmen"). The enzyme system according to the invention in the special detergent combines the optimally possible enzymes from fine and color detergents. The following table shows the formulation for a particularly preferred special detergent according to the invention (column "active content"), as well as other formulations which are the subject of the present invention (column "frame").
Ein„+“ in der letzten Spalte zeigt an, dass die angeführten Wirkstoffe bzw. Additive in einer dem Fachmann bekannten Menge vorhanden sein können, aber nicht unbedingt müssen (abgesehen von dem zwingend vorhandenen und weiter oben beschriebenen Enzymsystem). Erfindungsgemäß wichtig ist für die Waschmittelgrundlage/Tensidsystem ein Überhang an nichtionischen Tensiden gegenüber anionischen Tensiden, die bevorzugte Verwendung von Fettalkoholethersulfate als anionische Tenside, im Vergleich zu herkömmlichen Feinwaschmitteln nur eine geringe Menge von Seife zur Schaumkontrolle und die Vermeidung von Laurylsulfat oder Alkylbenzolsulfonate, sowie in wässriger Lösung einen nur leicht basischen pH-Wert, etwa im Bereich von unter 8,0, vorzugsweise um 7,5. A "+" in the last column indicates that the listed active ingredients or additives may be present in an amount known to those skilled in the art, but need not necessarily (apart from the compulsory enzyme system described above). According to the invention is important for the detergent base / surfactant system, an overhang of nonionic surfactants to anionic surfactants, the preferred use of fatty alcohol ether sulfates as anionic surfactants, compared to conventional mild detergents only a small amount of soap for foam control and the prevention of lauryl sulfate or alkylbenzenesulfonates, as well as in aqueous Solution only slightly basic pH, for example in the range of less than 8.0, preferably around 7.5.
Es versteht sich, dass anstelle der in der obigen Tabelle angegebenen Inhaltsstoffe auch gleichwertige Verbindungen verwendet werden können, solange die zuvor angegebenen erfindungsgemäß wichtigen Vorgaben erfüllt sind. It is understood that equivalent compounds can be used instead of the ingredients given in the above table, as long as the previously specified according to the invention important requirements are met.
