Abstract

Detergents which, besides inorganic and/or organic peracids, contain specific bis-benzofuranyl compounds as optical brighteners are stable for several months and show the usual cleaning properties even at washing temperatures of 20-60 DEG C.

Description

Die Anmeldung betrifft lagerstabile Waschmittel, die neben mindestens einer Persäure oder deren Salze mindestens einen spezifischen optischen Aufheller vom Bis-benzofuranyl-Typ enthalten, sowie deren Herstellung und Verwendung zum Waschen von Textilien.The application relates to storage-stable detergents which, in addition to at least one peracid or its salts, contain at least one specific optical brightener of the bis-benzofuranyl type, and to their preparation and use for washing textiles.

Begründet durch den gestiegenen Anteil an Kunstfasern bzw. Mischfasern in den heute hergestellten Textilien, dem Wunsch, bunte Wäsche nicht mehr separat zu waschen sowie aus Energie-Sparmassnahmen wird in vielen Ländern die Wäsche nicht mehr bei 90°C-95°C oder beim Kochen sondern bei tieferen Temperaturen gewaschen. Diese führte dazu, dass die bislang meistens in Waschmitteln enthaltenen, als Bleichmittel wirkenden, Perborate durch Hilfsmittel wie z.B. Tetraacetylethylendiamin (TAED) aktiviert werden mussten, um akzeptable Bleicheffekte auch bei Wasch­temperaturen von 60-80°C zu erlangen. Bei noch tieferen Waschtemperaturen liefern auch die Perborat/Aktivator-Systeme keine befriedigenden Ergeb­nisse mehr.Founded by the increased proportion of synthetic fibers or mixed fibers in the textiles manufactured today, the desire to no longer wash colored laundry separately, and energy-saving measures, laundry is no longer at 90 ° C-95 ° C or in cooking in many countries but washed at lower temperatures. This has led to the fact that the perborates, which have so far mostly been used in detergents and act as bleaching agents, are produced by auxiliary agents such as Tetraacetylethylenediamine (TAED) had to be activated in order to achieve acceptable bleaching effects even at washing temperatures of 60-80 ° C. At even lower washing temperatures, the perborate / activator systems also no longer provide satisfactory results.

Seit einiger Zeit werden daher Waschmittel beschrieben (DE-OS-27 56 583, EP-A-145 438, GB-2 141 754, GB-2 141 755, US-4 028 263, GB-59 272), die stärkere Bleichmittel wie z.B. Persäuren enthalten. Diese neuen Bleich­mittel zeigen einerseits zwar hervorragende Bleicheffekte schon bei Temperaturen ab 20°C, andererseits zerstören sie aber die üblichen in Waschmitteln enthaltenen optischen Aufheller.Detergents have therefore been described for some time (DE-OS-27 56 583, EP-A-145 438, GB-2 141 754, GB-2 141 755, US-4 028 263, GB-59 272), the stronger bleach such as peracids. On the one hand, these new bleaching agents show excellent bleaching effects even at temperatures from 20 ° C, on the other hand they destroy the usual optical brighteners contained in detergents.

Es wurde nun gefunden, dass spezielle Bis-benzofuranyl-Verbindungen über­raschenderweise eine ausgezeichnete Stabilität in Waschmitteln aufweisen, die solche starken Bleichmittel enthalten. Unter durchschnittlichen Lagerbedingungen und sogar unter verschärften Bedingungen (Temperaturen über 30°C und Luftfeuchtigkeit über 60 %) sind diese speziellen Bis-ben­zofuranyl-Aufheller im Waschmittel über mehrere Monate vollständig stabil oder werden höchstens in einem für die Praxis nicht störenden Mass abgebaut.It has now been found that special bis-benzofuranyl compounds surprisingly have excellent stability in detergents which contain such strong bleaches. Under average storage conditions and even under more stringent conditions (temperatures above 30 ° C and air humidity above 60%), these special bis-benzofuranyl brighteners in detergents are completely stable over several months or are broken down at most to a degree that is not disturbing in practice.

Gegenstand der Anmeldung sind somit lagerstabile Waschmittel enthal­tend 0,5 bis 30 % einer anorganischen Persäure oder Diperoxydodecan­disäure als organische Persäure oder deren Salze oder Mischungen von Persäuren oder deren Salze sowie 0,03 % bis 0,5 % eines optischen Aufhellers oder eine Mischung von optischen Aufhellern, der Formel (I)

Diese optischen Aufheller der Formel I und II sind bekannt und können nach bekannten Methoden hergestellt werden (DE-OS-2 238 734).These optical brighteners of the formula I and II are known and can be prepared by known methods (DE-OS-2 238 734).

Bei den Persäuren bzw. deren Salze handelt es sich um in der Literatur beschriebene oder auf dem Markt befindliche organische oder anorganische Verbindungen die Textilien schon bei Temperaturen ab 20°C bleichen. Als organische Persäure ist Diperoxydodecandisäure (DPDDA) von Interesse. Die einzusetzende Menge an organischer Persäure liegt vorzugsweise bei 0,5 % bis 10 %, insbesondere 1 % bis 5 %. Es können aber auch sehr wirksame, anorganische Persäuren wie Persulfat und/oder Percarbonat eingesetzt werden. Die Mengen anorganischer Persäuren liegt vorzugsweise bei 1 % bis 30 %, insbesondere 10 % bis 20 %, bezogen auf das gesamte Wasch­mittelgewicht und gegebenenfalls sowie vorteilhaft in Kombination mit kleinen Mengen katalytisch wirkender bivalenter Metall-Salze, wie sie in der US-4 655 782 und US-4 655 953 beschrieben werden. Bevorzugt werden Metallsalze von Kupfer und/oder Mangan verwendet.The peracids or their salts are organic or inorganic compounds described in the literature or on the market which bleach textiles even at temperatures from 20 ° C. Diperoxydodecanedioic acid (DPDDA) is of interest as organic peracid. The amount of organic peracid to be used is preferably 0.5% to 10%, in particular 1% to 5%. However, very effective, inorganic peracids such as persulfate and / or percarbonate can also be used. The amount of inorganic peracids is preferably 1% to 30%, in particular 10% to 20%, based on the total weight of the detergent and optionally and advantageously in combination with small amounts of catalytic bivalent metal salts, as described in US Pat. No. 4,655,782 and U.S. 4,655,953. Metal salts of copper and / or manganese are preferably used.

Selbstverständlich können auch Mischungen der organischen und/oder anorganischen Persäuren bzw. -Salzen eingesetzt werden.Mixtures of the organic and / or inorganic peracids or salts can of course also be used.

Die Zugabe der Persäuren in das Waschmittel erfolgt vor allem durch Mischen der Komponenten z.B. mit Hilfe von Schnecken-Dosier-Systemen und/oder Wirbelschicht-Mischern.The peracids are mainly added to the detergent by mixing the components e.g. with the help of screw dosing systems and / or fluidized bed mixers.

Bei den Waschmitteln handelt es sich um trockene Waschmittel üblicher Zusammensetzungen. In der Regel enthalten sie neben der erfindungsge­mässen Kombination aus Persäure und Aufheller, beispielsweise anioni­sche, nicht-ionogene, amphotere und/oder kationische Tenside, Builder wie z.B. Pentanatriumtripolyphosphat oder Ersatzprodukte wie Phosphonate, Polycarboxylate, Acryl-Malein-Copolymere, Zeolithe, Nitrilotriacetat, Ethylendiaminotetraessigsäure, Schmutzsuspendiermittel wie z.B. Natri­umcarboxymethylcellulose, Salze zur Einstellung des pH-Werts wie z.B. Alkali- oder Erdalkalisilikate, Schaum-Regulatoren wie z.B. Seife, Salze zur Einstellung der Sprühtrocknungs- und Granulat-Eigenschaften wie z.B. Natriumsulfat, Parfums, sowie gegebenenfalls antistatische und weich­machende Mittel, Enzyme, Photobleichmittel, Pigmente und/oder Nuan­cierungsmittel. Selbstverständlich sollen diese Bestandteile gegenüber dem eingesetzten Bleichsystem stabil sein.The detergents are dry detergents of conventional compositions. As a rule, in addition to the combination of peracid and brightener according to the invention, they contain, for example, anionic, nonionic, amphoteric and / or cationic surfactants, builders such as, for example, pentasodium tripolyphosphate or substitute products such as phosphonates, polycarboxylates, acrylic-maleic copolymers, zeolites, nitrilotriacetate, Ethylene diaminotetraacetic acid, soil suspending agents such as sodium carboxymethyl cellulose, salts for adjusting the pH such as alkali or alkaline earth silicates, foam regulators such as soap, salts for adjusting the spray drying and granulate properties such as sodium sulfate, perfumes, and optionally antistatic and softening agents , Enzymes, photobleaches, pigments and / or shading agents. Of course, these components should be stable with respect to the bleaching system used.

Dank der erfindungsgemässen Kombination ist es möglich, Waschmittel anzubieten, die dem üblichen Standard wie z.B. punkto Waschkraft, Fleckenentfernung, Erfrischung des Aussehens der gewaschenen Artikel ent­sprechen, auch wenn bei Temperaturen von 20°C-60°C gewaschen wird. Vorteilhafterweise können somit Buntwäsche und Weisswäsche unabhängig von der Faser zusammen gewaschen werden.Thanks to the combination according to the invention, it is possible to offer detergents which meet the usual standard, e.g. in terms of washing power, stain removal, refreshment of the appearance of the washed items, even when washing at temperatures of 20 ° C-60 ° C. Colored laundry and white laundry can thus advantageously be washed together regardless of the fiber.

Die nachfolgenden Beispiele erläutern die Erfindung, ohne sie darauf zu beschränken. Prozent-Angaben sind Gewichtsprozente.The following examples illustrate the invention without restricting it. Percentages are percentages by weight.

WaschmittelzubereitungDetergent preparation

Die Waschmittel der folgenden Beispiele werden nach dem üblichen Ver­fahren, in zwei Stufen hergestellt:
Zuerst wird ein Granulat A durch Trocknung und Granulierung eines Slurry bestehend aus ca. 1 Teil Wasser und 1 Teil Waschmittel folgender Zusam­mensetzung hergestellt: 84 g Lineares Dodecylbenzolsulfonat 31 g Talgalkohol-tetradecan-äthylenglykoläther (14 AeO) 37 g Na-Seife (vorwiegend aus Behen-Säure und C₁₄-C₂₀) 458 g Na-Tripolyphosphat 79 g Na-Silikat 20 g Mg-Silikat 12 g Carboxymethylcellulose 2 g Aethylendiamin-tetraacetat 222 g Na-Sulfat 1 g optische Aufheller (FWA) gemäss der Formel (I)-(II). The detergents of the following examples are produced in two stages by the usual method:
First, a granulate A is produced by drying and granulating a slurry consisting of approx. 1 part water and 1 part detergent of the following composition: 84 g Linear dodecylbenzenesulfonate 31 g Tallow alcohol-tetradecane-ethylene glycol ether (14 AeO) 37 g Na soap (mainly from behenic acid and C₁₄-C₂₀) 458 g Na tripolyphosphate 79 g Na silicate 20 g Mg silicate 12 g Carboxymethyl cellulose 2 g Ethylenediamine tetraacetate 222 g Na sulfate 1 g optical brighteners (FWA) according to the formula (I) - (II).

Zu 500 g dieses Granulats A, das nach der Trocknung eine Restfeuchte von ∼5 % aufweist, wird die Persäure B (15 g DPDDA) im trockenen Zustand homogen zugemischt.The peracid B (15 g DPDDA) is homogeneously mixed into 500 g of this granulate A, which has a residual moisture of ∼5% after drying.

LagertestStorage test

Proben des so erhaltenen Waschmittels W (Granulat A + Persäure B) werden:
- einerseits zur Kontrolle des Ausgangswertes, sofort durch Extraktion und spektrophotometrische Extinktions-Messung auf den Gehalt an FWA bestimmt, (theorretisch: 0.1 % FWA bezogen auf das Gewicht des Granu­lats A)
- andererseits in Handels-Waschpulver gerechten Karton-Paketen, d.h. mit Beschichtung, unter ausgewählten und kontrollierten Temperatur- und Luftfeuchtigkeits-Bedingungen während bestimmten Zeit-Perioden ge­lagert. Nach der Lagerung wird von jedem Waschmittel sofort der Gehalt an FWA bestimmt. Der Unterschied zum Ausgangswert, in Prozent ausge­drückt, ist ein Mass für die Stabilität des FWA gegenüber dem ent­sprechenden Bleichmittel im Waschpulver.Samples of the detergent W thus obtained (granules A + peracid B) are:
- On the one hand to check the initial value, immediately determined by extraction and spectrophotometric extinction measurement for the FWA content, (theoretically: 0.1% FWA based on the weight of the granulate A)
- On the other hand stored in commercial washing powder-compatible cardboard packages, ie with a coating, under selected and controlled temperature and humidity conditions for certain periods of time. After storage, the FWA content of each detergent is determined immediately. The difference from the initial value, expressed as a percentage, is a measure of the stability of the FWA against the corresponding bleach in the washing powder.

Die oben erwähnte FWA-Bestimmung wird wie folgt durchgeführt:
Das Waschpulver wird durch Mahlen gut homogenisiert und 1 g davon wird mit 200 ml Lösungsmittel, bestehend aus 9 Teilen Dimethylsulfoxid und 1 Teil Wasser versetzt, und bei Raumtemperatur während 30 Minuten gerührt. Dann wird während 30 Minuten zentrifugiert. Von der so erhal­tenen, klaren Lösung wird eine Probe mit einer Pipette in eine 1 cm Quarz-Küvette transferiert und deren Extinktion im UV-Bereich, beim Absorptionsmaximum gegen eine Standard-Lösung des jeweiligen FWA ge­ messen. Die Extinktion ist der FWA-Konzentration proportional. Die Reproduzierbarkeit der Resultate liegt bei ca. ± 1 %, sofern die Test-­Bedingungen genau gleich eingehalten werden.The FWA determination mentioned above is carried out as follows:
The washing powder is homogenized well by grinding and 1 g of it is mixed with 200 ml of solvent consisting of 9 parts of dimethyl sulfoxide and 1 part of water and stirred at room temperature for 30 minutes. Then it is centrifuged for 30 minutes. From the clear solution thus obtained, a sample is transferred with a pipette into a 1 cm quartz cuvette and its absorbance in the UV range, at the absorption maximum against a standard solution from the respective FWA measure up. The extinction is proportional to the FWA concentration. The reproducibility of the results is approx. ± 1% if the test conditions are observed exactly the same.
