Abstract
A stable liquid detergent builder-free composition comprises a) the carboxymethylated or carboxyethylated reaction product 5 of a fatty alcohol or an alkylphenol with ethylene oxide, this preferably being a compound of formula I or a salt thereof: R1-O-(CH2CH2O)n-(R2-COOH)x (I) in which R1 is C8-22 alkyl; C8-22 alkenyl or C4-18 alkylphenyl group; R2 is methylene or ethylene; n is a number from 1 to 20; and x is an average value from 0.1 to 1; b) one or more fatty acid salts; and c) one or more further anionic tensides. These compositions are useful as domestic laundry detergents.
Description
Sowohl in der Haushaltswäsche als auch in der Industriewäsche werden vermehrt flüssige Waschmittel eingesetzt. Diese enthalten meistens eine Mischung von anionischen und nicht-ionischen Tensiden und keine "Builder" (Gerüststoffe), so dass deren Waschwirkung bei fettigen Anschmutzungen trotz hohem Tensidanteil (ca. 40%) mässig ist. Für eine gute Waschwirkung auf proteinischen Anschmutzungen muss ein Enzym (Protease) zugesetzt werden.
Es wurde gefunden, dass flüssige Waschmittel, die ein carboxymethyliertes bzw. carboxyäthyliertes Aethylenoxydaddukt von Fettalkoholen oder Alkylphenolen neben Fettsäure(n) und anderen anionischen Tensiden enthalten, nicht nur eine hervorragende Waschwirkung bei normalen Verschmutzungen, sondern auch ohne Enzym eine hohe Waschwirkung auf proteinischen Anschmutzungen aufweisen.
Gegenstand der Erfindung sind flüssige Waschmittel enthaltend ein carboxymethyliertes oder carboxyäthyliertes Aethylenoxydaddukt eines Fettalkohols oder eines Alkylphenols, eine oder mehrere Fettsäuren und eines oder mehrere sonstige anionische Tenside sowie Alkali zur Neutralisierung.
Solche Waschmittel enthalten in wässriger Lösung von 1 bis 25, bevorzugt 4 bis 20 Gew.-% carboxymethyliertes bzw. carboxyäthyliertes Aethylenoxydaddukt von Fettalkoholen oder Alkylphenolen, 5 bis 30, bevorzugt 10 bis 25 Gew.-% einer Fettsäure und 2 bis 20, bevorzugt 5 bis 15 Gew.-% eines weiteren anionischen Tensides, zusammen 20 bis 50, bevorzugt 30 bis 50 Gew.-% Tensid, sowie eine genügende Menge Alkali zur Neutralisierung dieser Säuren. Ausserdem können diese Waschmittel noch übliche Bestandteile von flüssigen Waschmitteln, wie hydrotrope Mittel, Sequestriermittel, Puffer, Enzym und Aufheller enthalten.
Die carboxymethylierten bzw. carboxyäthylierten Aethylenoxydaddukte von Fettalkoholen oder Alkylphenolen entsprechen bevorzugt der allgemeinen Formel
R1-O-(CH2CH2O)n-(R2-COOH)x,
worin
R1 für den Rest eines Fettalkohols mit 8-22 C-Atomen oder eines Alkylphenols mit 10-24 C-Atomen,
R2 für eine Methylen- oder Aethylengruppe,
n für eine Zahl von 1 bis 20 und
x für einen durchschnittlichen Wert von 0,1 bis 1 stehen.
Diese Verbindungen sind bekannt bzw. können nach allgemein bekannten Methoden hergestellt werden. Als bevorzugte Verbindung wird ein Produkt eingesetzt, das durch Umsetzung eines synthetischen Laurylalkohols (C12-15) mit 4-5 Mol Aethylenoxyd und 0,8 Mol Chloressigsäure hergestellt wird. Diese Produkte fallen normalerweise in neutralisierter Form, d.h. als Alkalisalze, insbesondere als Natriumsalze an und werden bevorzugt in dieser Form eingesetzt.
Unter Fettsäuren sind gesättigte und ungesättigte C5-22-, vorzugsweise C12-18-Carbonsäuren zu verstehen. Diese Fettsäuren, wie z.B. Cocosfettsäure oder Oelsäure, werden als solche eingesetzt, aber durch Zusatz von Alkali wie Natrium- oder Kaliumhydroxyd, Triäthanolamin neutralisiert.
Als weitere anionische Tenside kommen die allgemein bekannten, wie z.B.
- Sulfate und Sulfonate von Fettsäuren, Fettsäureestern und Fettsäureamiden,
- lineare oder verzweigte Alkyl(C5-18)-sulfate und -sulfonate,
- Sulfate äthoxylierter Produkte, so vor allem Sulfate von nichtionischen Tensiden,
- Polykarbonsäureestersulfonate,
- Alkyl(C5-18)benzolsulfonate und Alkyl(C1-4)- oder Dialkyl(C1-4)naphthalinsulfonate
in Frage. Als Säuren eingesetzt, werden sie durch Zusatz von Alkali neutralisiert.
Als hydrotrope Verbindungen kommen z.B. Harnstoff, Dicyandiamid und Derivate, Alkohole, wasserlösliche Glykole, Glykoläther, Glykolester, C1-4-alkylsubstituierte Benzolsulfonate in Frage, vorausgesetzt, dass diese Verbindungen in destilliertem Wasser bis zur Kochtemperatur keinen Trübungspunkt aufweisen bzw. wasserlöslich bleiben. Sie dienen zur Vermeidung einer Phasentrennung, d.h. zur Stabilisierung der Flüssigform.
Als Sequestriermittel werden Zitronensäure, Nitrilotriessigsäure und sonstige komplexierende Verbindungen eingesetzt.
Puffer werden hinzugefügt, um den pH der Waschflotte im neutralen oder alkalischen Bereich zu stabilisieren. Als solche können Natriumhydrogencarbonat, Natriumcarbonat oder Natriumsilikat verwendet werden.
Durch Abstimmung dieser verschiedenen Zusätze und durch die fakultative Verwendung von üblichen Enzymen (Proteasen, Amylasen) und optischen Aufhellern kann die Waschwirkung der flüssigen Waschmittel je nach gewünschtem Anwendungsbereich optimal gestaltet werden. Diese flüssigen Waschmittel können vor allem in der Haushaltswäsche anstelle der bekannten phosphathaltigen oder phosphatfreien Waschmittel eingesetzt werden.
In den nachfolgenden Beispielen (Tabelle) werden das carboxymethylierte Aethylenoxydaddukt der Formel
C12-15-O-(CH2CH2O)4,5-(CH2-COONa)0,8
als 50%ige Paste, die Nitrilotriessigsäure (NTA) als 40%ige Lösung und 30%ige Natronlauge bis zu einem pH-Wert von 7,5 eingesetzt. Das sekundäre Alkansulfonat wird als Natriumsalz in 60%iger Lösung, das Lauryläthersulfat auch als Natriumsalz in 67%iger Lösung eingesetzt.

<tb></TABLE>
Liquid detergents are increasingly used in both household and industrial laundry. These usually contain a mixture of anionic and non-ionic surfactants and no "builders" (builders), so that their washing effect is moderate despite greasy soiling despite the high surfactant content (approx. 40%). An enzyme (protease) must be added for a good washing effect on protein stains.
It has been found that liquid detergents which contain a carboxymethylated or carboxyethylated ethylene oxide adduct of fatty alcohols or alkylphenols in addition to fatty acid (s) and other anionic surfactants not only have an excellent washing action with normal soiling, but also without an enzyme a high washing action on protein soils .
The invention relates to liquid detergents containing a carboxymethylated or carboxyethylated ethylene oxide adduct of a fatty alcohol or an alkylphenol, one or more fatty acids and one or more other anionic surfactants and alkali for neutralization.
Such detergents contain in aqueous solution from 1 to 25, preferably 4 to 20% by weight of carboxymethylated or carboxyethylated ethylene oxide adduct of fatty alcohols or alkylphenols, 5 to 30, preferably 10 to 25% by weight of a fatty acid and 2 to 20, preferably 5 up to 15% by weight of a further anionic surfactant, together 20 to 50, preferably 30 to 50% by weight of surfactant, and a sufficient amount of alkali to neutralize these acids. In addition, these detergents can also contain conventional constituents of liquid detergents, such as hydrotropic agents, sequestering agents, buffers, enzymes and brighteners.
The carboxymethylated or carboxyethylated ethylene oxide adducts of fatty alcohols or alkylphenols preferably correspond to the general formula
R1-O- (CH2CH2O) n- (R2-COOH) x,
wherein
R1 for the rest of a fatty alcohol with 8-22 carbon atoms or an alkylphenol with 10-24 carbon atoms,
R2 for a methylene or ethylene group,
n for a number from 1 to 20 and
x stand for an average value of 0.1 to 1.
These compounds are known or can be prepared by generally known methods. The preferred compound used is a product which is prepared by reacting a synthetic lauryl alcohol (C12-15) with 4-5 mol of ethylene oxide and 0.8 mol of chloroacetic acid. These products usually fall in neutralized form, i.e. as alkali salts, in particular as sodium salts, and are preferably used in this form.
Fatty acids are to be understood as saturated and unsaturated C5-22, preferably C12-18, carboxylic acids. These fatty acids, e.g. Coconut fatty acid or oleic acid are used as such, but neutralized by adding alkali such as sodium or potassium hydroxide, triethanolamine.
Other well-known anionic surfactants are those known, e.g.
- sulfates and sulfonates of fatty acids, fatty acid esters and fatty acid amides,
linear or branched alkyl (C5-18) sulfates and sulfonates,
Sulfates of ethoxylated products, especially sulfates of nonionic surfactants,
- polycarboxylic acid ester sulfonates,
- alkyl (C5-18) benzenesulfonates and alkyl (C1-4) - or dialkyl (C1-4) naphthalenesulfonates
in question. Used as acids, they are neutralized by adding alkali.
As hydrotropic compounds e.g. Urea, dicyandiamide and derivatives, alcohols, water-soluble glycols, glycol ethers, glycol esters, C1-4-alkyl-substituted benzenesulfonates in question, provided that these compounds have no cloud point or remain water-soluble in distilled water up to the boiling temperature. They serve to avoid phase separation, i.e. to stabilize the liquid form.
Citric acid, nitrilotriacetic acid and other complexing compounds are used as sequestering agents.
Buffers are added to stabilize the pH of the wash liquor in the neutral or alkaline range. As such, sodium bicarbonate, sodium carbonate or sodium silicate can be used.
By coordinating these various additives and through the optional use of conventional enzymes (proteases, amylases) and optical brighteners, the washing effect of the liquid detergents can be optimally designed depending on the desired application. These liquid detergents can be used primarily in household laundry instead of the known phosphate-containing or phosphate-free detergents.
In the following examples (table) the carboxymethylated ethylene oxide adduct of the formula
C12-15-O- (CH2CH2O) 4.5- (CH2-COONa) 0.8
as a 50% paste, nitrilotriacetic acid (NTA) as a 40% solution and 30% sodium hydroxide solution up to a pH of 7.5. The secondary alkane sulfonate is used as the sodium salt in 60% solution, the lauryl ether sulfate as the sodium salt in 67% solution.
