Abstract
Description
Die Erfindung betrifft wasserlösliche, bleichmittelhaltige Waschmittel und Waschhilfsmittel, die bei 20-30 Grad Celsius Anwendungstemperatur Bleichergebnisse bei der Entfernung von bleichbaren Flecken ergeben, die sonst nur bei 60 bzw. 35 Grad Celsius zu erreichen sind. Durch dieses wirkungsvolle Bleichen bei so niedrigen Anwendungstemperaturen ergibt sich außerdem eine gesteigerte Keimreduzierung und damit verbunden verbesserte hygienische Bedingungen. Zusätzlich resultiert eine deutliche Herabsetzung des zum Waschen und Bleichen notwendigen Energie bedarfs.The invention relates to water-soluble bleaching agents Detergents and washing aids that are at 20-30 degrees Celsius Application temperature bleaching results when removing bleachable stains result, which otherwise only at 60 or 35 degrees Celsius can be reached. Through this effective bleaching at such low application temperatures there is also a increased germ reduction and associated improved hygienic conditions. In addition, a clear result Reduction of the energy necessary for washing and bleaching requirement.
Beim gegenwärtigen Stand der Waschmittelchemie werden zum Bleichen bei 95 und 60 Grad Celsius Natriumperborat Tetra- oder Monohydrat bzw. Natriumpercarbonat angewandt. Um die Bleichwirkung bei 60 Grad C zu verstärken wird Tetraacethylethylendiamin (TAED) als Bleichaktivator eingesetzt. Durch die Bleichaktivierung ergeben sich bei 60 Grad C akzeptable Bleichergebnisse bei niederigen Wasch- bzw. Bleichtemperaturen, z. B. 40 oder 30 Grad C, wird die Entfernung von bleichbaren Anschmutzungen unbefriedigend.At the current level of detergent chemistry are used for bleaching at 95 and 60 degrees Celsius sodium perborate tetra or monohydrate or sodium percarbonate applied. To reduce the bleaching effect at 60 Grade C is called tetraacethylethylenediamine (TAED) Bleach activator used. Obtained through bleach activation acceptable bleaching results at low temperatures at 60 degrees C. Washing or bleaching temperatures, e.g. B. 40 or 30 degrees C, the Unsatisfactory removal of bleachable stains.
Um bei 30 Grad C gute Bleichergebnisse zu bekommen müßen bleichend wirkende Substanzen, die in diesem Temperaturbereich bleichaktiven Sauerstoff freigeben eingesetzt werden. Diese Eigenschaft zeigen Imidoperoxicarbonsäuren (PAP). Der Einsatz in Universalwaschmittel oder bleichenden Waschhilfsmitteln ist wie sich zeigte mit neuen Bedingungen bei der Gestaltung des Alkaligerüstes verbunden, wie dies im Rahmen dieser Anmeldung gezeigt wird.To get good bleaching results at 30 degrees C you need to bleach active substances that are bleach-active in this temperature range Oxygen release can be used. Show this property Imidoperoxy carboxylic acids (PAP). Use in universal detergents or bleaching detergents is as shown with new ones Conditions associated with the design of the alkali scaffold, such as this is shown in the context of this application.
Die Entwicklungen wurden mit Phthalimidoperoxihexansäure durch geführt, wobei die Aufgabe darin bestand diese PAP in ein Gerüst von wasserlöslichen Alkalien zu integrieren, die für eine gute Waschwirkung erforderlich sind. So mußten sich Alkalien mit hohen pH-Werten, z. B. Schichtsilikat, pH über 11, einsetzen lassen. Es durfte nicht nur die Bleichwirkung optimiert werden, sondern es mußte gleichzeitig die Verhinderung von Gewebeinkrustationen und eine gute Waschwirkung gegenüber Pigmentanschmutzungen bei niedrigen Waschtemperaturen von 30 Grad C gegeben sein. The developments were carried out with phthalimidoperoxihexanoic acid led, the task was to put this PAP into a scaffold of water-soluble alkalis to integrate that for good Washing effects are required. So alkalis had to be high pH values, e.g. B. Use layered silicate, pH above 11. It not only could the bleaching effect be optimized, but it had to prevent tissue incrustation and a good washing effect against pigment soiling low washing temperatures of 30 degrees C.
Das Optimum an Bleichwirkung wird bei Phthalimidoperoxihexansäure im Bereich um pH 9,5 erzielt. Dieser pH-Bereich mußte in alkalischen und PAP-haltigen Vollwaschmitteln und bei der Kombination zwischen PAP-haltigen bleichende Waschhilfsmitteln und stark alkalischen bleichmittelfreien Waschmitteln erreicht werden.The optimum bleaching effect is achieved with phthalimidoperoxyhexanoic acid achieved in the range around pH 9.5. This pH range had to be in alkaline and PAP-containing laundry detergents and at Combination between PAP-containing bleaching detergents and strongly alkaline bleach-free detergents can be achieved.
Zur Erreichung des optimalen pH-Wertes wurde eine im Waschmittelbereich allgemein nicht übliche Abpufferung der relativ starken alkalischen Reaktionen durch Alkalisilikate, insbesondere Schichtsilikat mit Hilfe von Zitronensäure vorgenommen. Neben der pH-Werteinstellung wurde durch Umsetzung der Anteile von Na- Hydrogencarbonat bzw. Na-Carbonat in der Rezeptur Natriumcitrat erhalten, das die Bindung der Wasserhärte als Komplexbildner über nimmt. Citronensäure bzw. deren Na-Salze haben bei niedrigen Waschtemperaturen ein gutes Ca-Bindevermögen (besser als Na- Triphosphat), sodaß neben der optimalen pH-Werteinstellung noch ein sehr gutes Ca-Bindevermögen zur Verhinderung von Ablagerungen gegeben ist.In order to achieve the optimal pH value, an im Detergent area generally not usual buffering the relative strong alkaline reactions due to alkali silicates, in particular Layered silicate made with the help of citric acid. In addition to the pH adjustment was made by converting the proportions of Na Hydrogen carbonate or Na carbonate in the recipe sodium citrate obtained, the binding of the water hardness as a complexing agent takes. Citric acid or its Na salts have at low Washing temperatures a good Ca binding capacity (better than Na Triphosphate), so that besides the optimal pH adjustment a very good Ca binding capacity to prevent deposits given is.
Ein Einsatz von Natriumcitrat allein als Rezepturbestandteil fuhrt nicht zu der gewünschten pH-Werteinstellung. Die beschriebene Reaktion zwischen Citronensäure und den mitverwendeten Carbonaten ergibt erwartungsgemäß eine starke sprudelnde CO2-Entwicklung.The use of sodium citrate alone as a component of the formulation leads not to the desired pH value setting. The one described Reaction between citric acid and the carbonates used results in a strong bubbling CO2 development as expected.
Als Beispiel werden Rezepturen angeführt, die unter Verwendung der Phthalimidoperoxihexansäure erprobt wurden.As an example, recipes are given using the Phthalimidoperoxihexanoic acid have been tried.

Um den pH-Wert von stark alkalischen Lösungen auf das für die Bleiche mit Phthalimidoperoxihexansäure notwendige Niveau zu bringen wird mit einer Kombination von Natriumhydrogencarbonat und Zitronensäure gearbeitet. Dabei wird der pH-Wert auf den vom Bleichmittel PAP bevorzugten Wert gebracht.To adjust the pH of strongly alkaline solutions to that for the Bleach with phthalimidoperoxihexanoic acid to the necessary level will bring with a combination of sodium hydrogen carbonate and Citric acid worked. The pH is adjusted to that of Bleach PAP brought preferred value.
Bei einer Kombination von
Rezeptur 2. - mit pH 6,52 - und
Rezeptur 3. - mit pH 11,3 -
wird durch die vorher beschriebenen Reaktionen der zum Bleichen
geeignete pH-Wert von 9,18 erhalten.With a combination of
Recipe 2. - with pH 6.52 - and
Recipe 3 - with pH 11.3 -
the pH of 9.18 suitable for bleaching is obtained by the reactions described above.
Neben der pH-Einstellung erfolgt die Bildung von Na-Citrat. Natrium -Citrat wiederum bindet bei niedrigen Waschtemperaturen von 20 bis, 30 Grad Celsius die Wasserhärte sehr gut. Dadurch wird weiches Wasser zum Waschen erhalten und somit werden störende Ablagerungen auf Textilien und Waschmaschinenbauteilen verhindert.In addition to the pH adjustment, Na citrate is formed. sodium -Citrate in turn binds at low washing temperatures from 20 to, 30 degrees Celsius the water hardness is very good. This makes it soft Get water for washing and thus annoying deposits prevented on textiles and washing machine components.
Nach dem gleichen Prinzip arbeitet die pH-Einstellung in Verbindung mit der Wasserenthärtung bei dem Vollwaschmittel der Rezeptur 1., wobei sich in diesem Falle ein pH-Wert von 8,98 einstellt.The pH adjustment in works on the same principle Connection with water softening in the heavy duty detergent Recipe 1., in which case a pH of 8.98 established.
Die Bleichwirkung dieser PAP-haltigen Rezepturen, eingesetzt bei 30 Grad C, ist vergleichbar mit der die durch marktgängige Vollwaschmittel bei 60 Grad C zu erzielen ist. Die durch diese Rezepturen meßbaren Ablagerungen nach 25 Wäschen liegen unter 1,0 % und sind damit wesentlich niedriger als der heute übliche Stand, der mit Vollwaschmitteln erhalten wird.The bleaching effect of these PAP-containing formulations used at 30 degrees C, is comparable to that of the marketable Heavy duty detergent can be achieved at 60 degrees C. The through this Deposits measurable after 25 washes are less than 1.0 % and are therefore significantly lower than the current level, which is obtained with heavy-duty detergents.
Durch Niedrigtemperaturwaschverfahren mit Vollwaschmitteln (Rezeptur 1) oder einer Kombination von einem bleichmittelhaltigen Waschhilfsmittel, das PAP enthält (Rezeptur 2), mit einem bleichmittelfreiem Buntwaschmittel (Rezeptur 3) wird eine erhebliche Menge an elektrischer Energie eingespart. Durch die PAP-Bleiche wenden außerdem die hygienischen Bedingungen im Niedrigtemperaturbereich erheblich verbessert. Dies bedeutet, daß weltweit Waschmittel mit PAP als Bleichmittel unabhängig von anwendungstechnischen Forderungen nach erhöhten Waschtemperaturen als Niedrigtemperaturwaschmittel zur Verbesserung der allgemeinen Hygiene eingesetzt werden können. Ländertypische Waschgewohnheiten können damit weitgehend unberücksichtigt bleiben.By low-temperature washing process with heavy-duty detergents (Recipe 1) or a combination of a bleaching agent Washing aid containing PAP (recipe 2) with a bleach-free color detergent (recipe 3) becomes a considerable amount of electrical energy saved. Through the PAP bleach also turn the hygienic conditions in the Low temperature range significantly improved. This means that worldwide detergents with PAP as bleach independent of technical requirements for increased washing temperatures as a low temperature detergent to improve general Hygiene can be used. Country-specific washing habits can be largely ignored.
