Definitions
- Textile detergents to be used in commercial laundries differ considerably in their composition from those which are usually used in the household.
- softened, ie Ca and Mg-free water is used regularly in commercial companies.
- the commercially used agents often contain highly alkaline builder salts and alkalis, such as sodium metasilicate and sodium hydroxide, which can be handled safely by a person skilled in the art, but are unsuitable in the household for safety reasons.
- These highly alkaline constituents can in turn interact with the surfactants usually present, in particular the nonionics from the class of the alkyl polyglycol ethers, and more or less decompose them if they are stored together for a long time.
- surfactants which are made from natural, i.e. renewable raw materials are available and are characterized by their complete and rapid biodegradability in wastewater.
- Highly alkaline cleaner concentrates for the industrial cleaning of metallic surfaces were known from EP-A-282 863. These agents contain 80 to 99.7 wt .-% of an aqueous solution of a builder mixture of alkali metal silicates and alkali metal hydroxides and 0.3 to 20 wt .-% of a surfactant combination of anionic surfactants, alkyl glucosides and other nonionic surfactants, with amounts of 0.1 to 10% by weight of alkyl glucosides and 0.1 to 5% by weight of nonionic surfactants in combination with 0.1 to 5% by weight of fatty acids or soaps are preferred.
- EP-A-202 638 describes liquid cleaning agents for strongly alkaline cleaning formulations. These surfactant concentrates, which contain nonionic surfactants and alkyl glucosides, but no alkaline builder substances, are only mixed with alkaline builder substances during practical use.
- WO-A-87/06949 further describes a liquid detergent which contains alkyl glucosides and builder substances which have a particular solubility. The solubility of relatively poorly soluble builder substances is supported by the use of alkyl glucosides.
- R is preferably a C8 ⁇ 12 alkyl radical, in particular a C8 ⁇ 10 alkyl radical.
- the alkyl glucosides can still contain small amounts of free fatty alcohol and glucose in their production. Those alkyl glucosides are preferably used whose content of fatty alcohols is less than 5% by weight, in particular less than 2% by weight (based on alkyl glucoside).
- the agents can optionally also contain nonionic surfactants of the ethoxylated fatty alcohol and oxo alcohol type with 12 to 18 carbon atoms and 5 to 10 ethylene glycol ether groups (EO).

Description
In gewerblichen Wäschereien anzuwendende Textilwaschmittel unterscheiden sich in ihrer ihrer Zusammensetzung erheblich von solchen, die üblicherweise im Haushalt verwendet werden. Einerseits wird in gewerblichen Betrieben regelmäßig mit enthärtetem, d.h. Ca- und Mg-freiem Wasser gearbeitet. Zum anderen enthalten die gewerblich angewendeten Mittel vielfach hochalkalische Buildersalze und Alkalien, wie Natriummetasilikat und Natriumhydroxid, die zwar vom Fachmann gefahrlos gehandhabt werden können, im Haushalt jedoch aus Sicherheitsgründen unangebracht sind. Diese hochalkalischen Bestandteile können ihrerseits mit den üblicherweise anwesenden Tensiden, insbesondere den Nonionics aus der Klasse der Alkylpolyglykolether, in Wechselwirkung treten und sie bei längerer gemeinsamer Lagerung mehr oder weniger zersetzen. Diese Probleme existieren insbesondere bei flüssigen Konzentraten und Produkten, die zum Ansetzen konzentrierter Stammlaugen (Stock-solutions) bestimmt sind und bei denen mangels einer räumlich Trennung von Tensid- und Alakalikomponente der zersetzende Einfluß besonders intensiv ist. Hochalkalische Flüssigprodukte und Stammlaugen haben vor pulverförmigen, gleichartig zusammengesetzten Mitteln den Vorzug, daß sie staubfrei und insbesondere automatisch dosiert werden können und somit keine Bedienungsprobleme aufwerfen.Textile detergents to be used in commercial laundries differ considerably in their composition from those which are usually used in the household. On the one hand, softened, ie Ca and Mg-free water is used regularly in commercial companies. On the other hand, the commercially used agents often contain highly alkaline builder salts and alkalis, such as sodium metasilicate and sodium hydroxide, which can be handled safely by a person skilled in the art, but are unsuitable in the household for safety reasons. These highly alkaline constituents can in turn interact with the surfactants usually present, in particular the nonionics from the class of the alkyl polyglycol ethers, and more or less decompose them if they are stored together for a long time. These problems exist in particular in the case of liquid concentrates and products which are intended for the preparation of concentrated stock liquors (stock solutions) and in which, due to the lack of a spatial separation of the surfactant and alkali components, the decomposing influence is particularly intense. Highly alkaline liquid products and base liquors have the advantage over powdery, similar compositions that they can be dosed dust-free and in particular automatically and therefore do not pose any operating problems.
Ein weiterer Aspekt ist eine möglichst weitgehende Verwendung von Tensiden, die aus natürlichen, d.h. nachwachsenden Rohstoffen erhältlich sind und sich durch eine vollständige und schnelle biologische Abbaufähigkeit im Abwasser auszeichnen.Another aspect is the greatest possible use of surfactants, which are made from natural, i.e. renewable raw materials are available and are characterized by their complete and rapid biodegradability in wastewater.
Weiterhin sollen derartige Mittel im Hauptwaschgang und während des Nachspülens keine störende Schaummengen entwickeln. Da übliche Entschäumer, wie Polysiloxane und Paraffinkohlenwasserstoffe beim Dispergieren in Flüssigwaschmitteln Wirkungsverluste erleiden bzw. im Falle der Polysiloxane durch Alkali zersetzt werden, muß die Tensidkomponente von sich aus schwach schäumend sein.Furthermore, such agents should not develop any troublesome amounts of foam in the main wash and during the rinsing. Since conventional defoamers, such as polysiloxanes and paraffin hydrocarbons, lose their effectiveness when dispersed in liquid detergents or, in the case of the polysiloxanes, are decomposed by alkali, the surfactant component must be inherently low-foaming.
Aus der EP-A-282 863 waren hochalkalische Reinigerkonzentrate für die industrielle Reinigung von metallischen Oberflächen bekannt. Diese Mittel enthalten 80 bis 99,7 Gew.-% einer wäßrigen Lösung eines Buildergemisches von Alkalimetallsilikaten und Alkalimetallhydroxiden und 0,3 bis 20 Gew.-% einer Tensidkombination aus anionischen Tensiden, Alkylglucosiden und anderen nichtionischen Tensiden, wobei Mengen von 0,1 bis 10 Gew.-% Alkylglucosiden und 0,1 bis 5 Gew.-% nichtionischen Tensiden in Kombination mit 0,1 bis 5 Gew.-% Fettsäuren bzw. Seifen bevorzugt sind. Zusätzliche Builder wie Nitrilotriessigsäure und Phosphonate können in Mengen von 0,1 bis 10 Gew.-% zugesetzt werden. EP-A-202 638 beschreibt flüssige Reinigungsmittel für stark alkalische Reinigungsformulierungen. Diese Tensidkonzentrate, die nichtionische Tenside und Alkylglucoside, aber keine alkalischen Buildersubstanzen enthalten, werden erst bei der praktischen Anwendung mit alkalischen Buildersubstanzen versetzt. WO-A-87/06949 beschreibt weiterhin ein Flüssigwaschmittel, das Alkylglucoside und Buildersubstanzen enthält, die eine spezielle Löslichkeit aufweisen. Dabei wird die Löslichkeit relativ schwerlöslicher Buildersubstanzen durch den Einsatz von Alkylglucosiden unterstützt.Highly alkaline cleaner concentrates for the industrial cleaning of metallic surfaces were known from EP-A-282 863. These agents contain 80 to 99.7 wt .-% of an aqueous solution of a builder mixture of alkali metal silicates and alkali metal hydroxides and 0.3 to 20 wt .-% of a surfactant combination of anionic surfactants, alkyl glucosides and other nonionic surfactants, with amounts of 0.1 to 10% by weight of alkyl glucosides and 0.1 to 5% by weight of nonionic surfactants in combination with 0.1 to 5% by weight of fatty acids or soaps are preferred. Additional builders such as nitrilotriacetic acid and phosphonates can be added in amounts of 0.1 to 10% by weight. EP-A-202 638 describes liquid cleaning agents for strongly alkaline cleaning formulations. These surfactant concentrates, which contain nonionic surfactants and alkyl glucosides, but no alkaline builder substances, are only mixed with alkaline builder substances during practical use. WO-A-87/06949 further describes a liquid detergent which contains alkyl glucosides and builder substances which have a particular solubility. The solubility of relatively poorly soluble builder substances is supported by the use of alkyl glucosides.
Gegenstand der Erfindung, mit der die oben erwähnten Probleme gelöst werden, ist ein flüssiges, wäßriges, phosphatfreies Waschmittelkonzentrat, enthaltend 5 bis 20 Gew.-% einer nichtionischen Tensidkomponente (A), 15 bis 40 Gew.-% einer Builderkomponente (B), 0 bis 1 Gew.-% optische Aufheller, 0 bis 6 Gew.-% Hydrotrope, 0 bis 10 Gew.-% mit Wasser mischbare Alkohole bzw. Etheralkohole und sonstige fakultative nicht tensidische und nicht builderhaltige Waschmittelbestandteile sowie Wasser (Differenz bis 100 Gew.-%), wobei die Komponenten, bezogen auf das Waschmittel wie folgt zusammengesetzt sind:
- A1) 4 bis 20 Gew.-% eines Alkylglucosids der Formel I
R-O-Gx (I)
mit R = C₈-C₁₄-Alkylrest, G = Glucoserest und x = Zahlen von 1,2 bis 5, - A2) 0 bis 2 Gew.-% mindestens eines nichtionischen Tensids aus der Klasse der Alkylpolyglykolether mit C₁₂-C₁₈-Alkylgruppen und 5 bis 10 Ethylenglykolethergruppen,
- B1) 4 bis 20 Gew.-% Natriumhydroxid,
- B2) 0,5 is 12 Gew.-% Natriumsilikat der Zusammensetzung Na₂O : SiO₂ = 1:1 bis 1:3,4
- B3) 2 bis 12 Gew.-% Natrium-nitrilotriacetat,
- B4) 0 bis 3,5 Gew.-% Natriumsalz mindestens einer Phosphonsäure, mit der Maßgabe, daß der Anteil der Bestandteile (B3 + B4) 3 bis 12 Gew.-% beträgt.
- A1) 4 to 20% by weight of an alkyl glucoside of the formula I.
ROG x (I)
with R = C₈-C₁₄ alkyl radical, G = glucose radical and x = numbers from 1.2 to 5, - A2) 0 to 2% by weight of at least one nonionic surfactant from the class of the alkyl polyglycol ethers with C₁₂-C₁₈ alkyl groups and 5 to 10 ethylene glycol ether groups,
- B1) 4 to 20% by weight of sodium hydroxide,
- B2) 0.5 to 12% by weight sodium silicate of the composition Na₂O: SiO₂ = 1: 1 to 1: 3.4
- B3) 2 to 12% by weight of sodium nitrilotriacetate,
- B4) 0 to 3.5% by weight of sodium salt of at least one phosphonic acid, with the proviso that the proportion of constituents (B3 + B4) is 3 to 12% by weight.
Vorzugsweise beträgt der Gehalt der Mittel an den Einzelkomponenten
- A1) 5 bis 12 Gew.-%
- A2) 0,5 bis 1,5 Gew.-%
- B1) 6 bis 15 Gew.-%
- B2) 0,5 bis 3 Gew.%
- B3) 3 bis 10 Gew.-%
- B4) 0,2 bis 2 Gew.
- A1) 5 to 12% by weight
- A2) 0.5 to 1.5% by weight
- B1) 6 to 15% by weight
- B2) 0.5 to 3% by weight
- B3) 3 to 10% by weight
- B4) 0.2 to 2 wt.
Beispiele hierfür sind Octyl-, Nonyl-, Decyl-, Undecyl-, Dodecyl-und Tridecylalkohol sowie deren Gemische untereinander. Vozugsweise steht R für einen C₈₋₁₂-Alkylrest, insbesondere für einen C₈₋₁₀-Alkylrest. Bei der Umsetzung der Glucose oder glucosehaltigen Stärkeabbauprodukte mit den Alkoholen kommt es in Gegenwart saurer Acetalisierungs-Katalysatoren zu einer teilweisen Oligomerisierung der Glucose, wobei sich Gemische aus Alkylmonoglucosiden und Alkyloligogucosiden bilden. Der Parameter x gemäß Formel I bezeichnet somit einen mittleren Oligomerisierungsgrad. Dieser soll vorzugsweise 1,3 bis 3 betragen. Derartige Gemische sind gemeint, wenn im Zusammenhang mit der Erfindung allgemein von Alkylglucosiden die Rede ist.Examples include octyl, nonyl, decyl, undecyl, dodecyl and tridecyl alcohol and their mixtures with one another. R is preferably a C₈₋₁₂ alkyl radical, in particular a C₈₋₁₀ alkyl radical. When the glucose or starch degradation products containing glucose are reacted with the alcohols, partial glucose oligomerization occurs in the presence of acidic acetalization catalysts, with mixtures of alkyl monoglucosides and alkyl oligogucosides being formed. The parameter x according to formula I thus denotes an average degree of oligomerization. This should preferably be 1.3 to 3. Such mixtures are meant when the context of the invention generally refers to alkyl glucosides.
Von ihrer Herstellung her können die Alkylglucoside noch geringe Mengen an freiem Fettalkohol und Glucose enthalten. Vorzugsweise werden solche Alkylglucoside eingesetzt, deren Gehalt an Fettalkoholen weniger als 5 Gew.-%, insbesondere weniger als 2 Gew.-% (bezogen auf Alkylglucosid) beträgt.The alkyl glucosides can still contain small amounts of free fatty alcohol and glucose in their production. Those alkyl glucosides are preferably used whose content of fatty alcohols is less than 5% by weight, in particular less than 2% by weight (based on alkyl glucoside).
Fakultativ können die Mittel außer den Alkylglucosiden als Komponente (A2) noch nichtionische Tenside vom Typ der ethoxylierten Fettalkohole und Oxoalkohole mit 12 bis 18 C-Atomen und 5 bis 10 Ethylenglykolethergruppen (EO) enthalten. Geeignet sind z.B. von Kokos-, Talg- oder Palmkernfettalkoholen abgeleitete Ethoxylate mit einem HLB-Wert von mehr als 12, beispielsweise von 13 bis 18, sowie entsprechende Ethoxylate von Oxoalkoholen mit 12 bis 16 C-Atomen und 6 bis 8 EO-Gruppen.In addition to the alkyl glucosides as component (A2), the agents can optionally also contain nonionic surfactants of the ethoxylated fatty alcohol and oxo alcohol type with 12 to 18 carbon atoms and 5 to 10 ethylene glycol ether groups (EO). Suitable are e.g. Ethoxylates derived from coconut, tallow or palm kernel fatty alcohols with an HLB value of more than 12, for example from 13 to 18, and corresponding ethoxylates from oxo alcohols with 12 to 16 carbon atoms and 6 to 8 EO groups.
Die Builderkomponente besteht aus Natriumhydroxid (Bestandteil B1), Natriumsilikat (Bestandteil B2) und sequestrierend wirkenden polyanionischen Salzen, abgeleitet von Nitrilotriessigsäure (NTA) und ggf. Phosphonsäuren (Bestandteil B3 und B4).The builder component consists of sodium hydroxide (component B1), sodium silicate (component B2) and sequestering polyanionic salts derived from nitrilotriacetic acid (NTA) and possibly phosphonic acids (components B3 and B4).
Im Natriumsilikat kann das Na₂O : SiO₂-Verhältnis 1:1 (Metasilikat) bis 1:3,4 (Wasserglas) betragen. In Mitteln mit geringeren Anteilen an Natriumhydroxid wird im Interesse einer hohen Alkalität bevorzugt Metasilikat eingesetzt, während in Mitteln mit höheren Natriumhydroxid-Gehalten das Natriumsilikat überwiegend oder vollständig aus Wasserglas bestehen kann.In sodium silicate, the Na₂O: SiO₂ ratio can be 1: 1 (metasilicate) to 1: 3.4 (water glass). In the interest of a high alkalinity, metasilicate is preferably used in agents with a low proportion of sodium hydroxide, while in agents with a higher sodium hydroxide content the sodium silicate can consist predominantly or entirely of water glass.
Das NTA liegt als Trinatriumsalz vor und wird auch in dieser Form der Mengenberechnung zugrunde gelegt. Insbesondere beträgt sein Anteil 5 bis 10 Gew.-%.The NTA is available as a trisodium salt and is also used in this form of quantity calculation. In particular, its proportion is 5 to 10% by weight.
Als Phosphonat kommt in erster Linie das Natriumsalz der 1-Hydroxyethan-1,1-diphosphonsäure (HEDP) in Frage. Der Mengenberechnung wird das Tetranatriumsalz zugrunde gelegt. Brauchbar sind auch die Natriumsalze der Aminotrimethylenphosphonsäure (ATMP), Ethylendiamintetramethylenphosphonsäure (EDTMP), Diethylentriaminpentamethylenphosphonsäure (DTPMP) und deren höhere Homologen, jedoch ist EDTMP wegen ihrer z.Zt. ungeklärten Funktion im Abwasser weniger bevorzugt. Ihre Mengenberechnung basiert auf neutral reagierenden Natriumsalzen (Na₃-Salz bei ATMP, Na₅-Salz bei EDTMP, Na₆-Salz bei DTPMP). Die Summe der Komponenten B3 + B4 beträgt 3 bis 12 Gew.-%, vorzugsweise 6 bis 11 Gew.-%.The sodium salt of 1-hydroxyethane-1,1-diphosphonic acid (HEDP) is primarily suitable as the phosphonate. The quantity calculation is based on the tetrasodium salt. The sodium salts of aminotrimethylenephosphonic acid (ATMP), ethylenediaminetetramethylenephosphonic acid (EDTMP), diethylenetriaminepentamethylenephosphonic acid (DTPMP) and their higher homologs are also usable. unexplained function in wastewater less preferred. Your quantity calculation is based on neutral reacting sodium salts (Na₃ salt with ATMP, Na₅ salt with EDTMP, Na₆ salt with DTPMP). The sum of components B3 + B4 is 3 to 12% by weight, preferably 6 to 11% by weight.
Neben den vorgenannten Bestandteilen können die Mittel noch übliche, nicht als Tenside und Builder wirkende Waschmittelbestandteile enthalten. Hierzu zählen optische Aufheller in Anteilen bis zu 1 Gew.-%, vorzugsweise 0,05 bis 0,3 Gew.-%. Beispiele hierfür sind Derivate der Bis-(triazinylamino)-stilbendisulfonsäure, beispielsweise das Natriumsalz der 4,4'-Bis-(2-anilino-4-morpholino-1,3,5-triazin-6-yl-amino)-stilben-2,2'-disulfonsäure sowie der chlorierten Diphenyldistyryl-sulfonsäuren.In addition to the aforementioned constituents, the detergents can also contain conventional detergent constituents which do not act as surfactants and builders. These include optical brighteners in proportions of up to 1% by weight, preferably 0.05 to 0.3% by weight. Examples of these are derivatives of bis (triazinylamino) stilbene disulfonic acid, for example the sodium salt of 4,4'-bis (2-anilino-4-morpholino-1,3,5-triazin-6-yl-amino) -stilbene-2,2'-disulfonic acid and the chlorinated diphenyldistyrylsulfonic acids.

Die Hydrotrope können in Anteilen bis 6 Gew.-%, die Alkohole bzw. Etheralkohole in Anteilen bis 10 Gew.-% anwesend sein. Ferner können die Mittel Neutralsalze, wie Natriumsulfat und Natriumchlorid, als Begleitstoffe der eingesetzten Rohstoffe in untergeordneter Menge enthalten. Die Differenz bis 100 Gew.-% entfällt auf Wasser.Other optional components are enzymes, fragrances, dyes, hydrotropes and water-miscible solvents.

The hydrotropes can be present in proportions up to 6% by weight, the alcohols or ether alcohols in proportions up to 10% by weight. The agents can also contain neutral salts, such as sodium sulfate and sodium chloride, as minor substances in the raw materials used. The difference of up to 100% by weight is water.
Die Mittel sind haltbare, gießbare Flüssigkeiten, die sich sowohl zur automatischen Dosierung als auch zum Ansetzen von Vorratslösungen (Stammlaugen) eignen. Die Konzentrate sind bis zu Temperaturen von -10 °C noch flüssig und gegen Entmischen beständig. Ihre Anwendungskonzentration beträgt im allgemeinen 2 bis 10, vorzugsweise 3 bis 7 g/l.The agents are long-lasting, pourable liquids that are suitable for automatic dosing as well as for the preparation of stock solutions (base liquors). The concentrates are still liquid down to temperatures of -10 ° C and are resistant to segregation. Their application concentration is generally 2 to 10, preferably 3 to 7 g / l.
