Abstract
Description
- Die vorliegende Erfindung betrifft lagerstabile, wässrige, konzentrierte Aufhellerformulierungen und ein Verfahren zu deren Herstellung sowie deren Verwendung.
- Heutzutage werden optische Aufheller bevorzugt in Form wässriger Lösungen in den Handel gebracht. Hierzu wird der feuchte Filterkuchen oder auch das trockene Pulver mit Wasser aufgeschlämmt. Diese Suspension wird mit Dispergatoren und Verdickungsmitteln zur Erhöhung von Homogenität, Benetzbarkeit und Stabilität versetzt. Zu diesen Hilfsstoffen setzt man häufig noch einen Elektrolyten hinzu. Die bisher verwendeten Hilfsstoffe konnten jedoch ein Sedimentieren der Aufheller nicht über einen längeren Zeitraum verhindern.
- Es wurde nun überraschenderweise gefunden, dass man lagerstabile, konzentrierte, wässrige Aufhellerformulierungen erhält, wenn man zu der wässrigen Suspension derartiger Aufheller ein anionisches Polysaccharid in geringen Mengen zugibt. Derartige Suspensionen setzen sich während der Lagerung kaum ab. Zusätzlich zu dem guten Sedimentationsverhalten bleiben die Suspensionen während der Lagerung homogen.
- Die Formulierungen gemäss der Erfindung sind demnach gekennzeichnet durch einen Gehalt an:
- a) 10 bis 60 Gew.%, bezogen auf das Gesamtgewicht der Aufhellerformulierung eines anionischen optischen Aufhellers,
- b) 0,01 bis 1 Gew.%, bezogen auf das Gesamtgewicht der Aufhellerformulierung eines anionischen Polysaccharids und
- c) Wasser; sowie gegebenenfalls
- d) Hilfsstoffe.
- Diese Formulierungen stellen Suspensionen dar.
- Vorzugsweise enthalten solche Formulierungen anionische optische Aufheller, die mindestens einen Sulfonsäurerest enthalten.
- Beispielsweise handelt es sich um Aufheller der Triazinreihe der Formel:
- Von besonderem Interesse sind:
- Weiterhin kann man optische Aufheller der Distilbenreihe einsetzen. So zum Beispiel Verbindungen der Formel
- Bevorzugt sind solche Verbindungen in denen o = 2 ist.
-
-
- Als Halogene kommen vor allem Fluor, Chlor und Brom in Frage, insbesondere jedoch Chlor.
- Als C₁-C₄-Alkylreste kommen unverzweigte und verzweigte Alkylreste wie der Methyl-, Ethyl-, n- und iso-Propyl, n-, sec- und tert.-Butylrest in Betracht. Diese C₁-C₄-Alkylreste können ihrerseits substituiert sein mit z.B. Aryl-(Phenyl-, Naphthyl-), C₁-C₄-Alkyl-, C₁-C₄-Alkoxy-, OH- oder CN-Gruppen.
- Salzbildende Kationen M sind z.B. Alkalimetall-, Ammonium- oder Aminsalzionen. Unter Aminsalzionen sind solche der Formel H⁺NR₈R₉R₁₀ bevorzugt, in denen R₈, R₉ und R₁₀ unabhängig voneinander Wasserstoff, Alkyl, Alkenyl, Hydroxyalkyl, Cyanoalkyl, Halogenalkyl oder Phenylalkyl bedeuten oder worin R₈ und R₉ zusammen die Ergänzung zu einem 5-7-gliedrigen gesättigten Stickstoffheterocyclus darstellen, der noch zusätzlich ein Stickstoff- oder Sauerstoffatom als Ringglied enthalten kann, beispielsweise einen Piperidin-, Piperazin-, Pyrrolidin-, Imidazolin- oder Morpholinring, während R₁₀ für Wasserstoff steht.
- Bevorzugte Distyrylbiphenylverbindungen der Formel (X) sind solche in denen das Kation M ein Alkalimetall-, Ammonium-, oder Aminion ist, wobei aus praktischen Erwägungen Kalium und Natrium eine besondere Bedeutung haben.
- Die erfindungsgemäss verwendbaren anionischen Polysaccharide gehören zur Gruppe der modifizierten Polysaccharide, die sich von der Zellulose ableiten lassen. Es kann sich um veretherte Zellulose handeln, aber auch um Heteropolysaccharide, die in den Seitenketten weitere Monosaccharide wie z.B. Mannose und Glucuronsäure enthalten.
- Das anionische Polysaccharid ist zum Beispiel Na-Carboxymethylcellulose und besonders bevorzugt Xanthan.
- Die Menge an Polysaccharid beträgt vorzugsweise 0,01 bis 1 Gew.%, wobei ein Bereich von 0,05-0,5 Gew.% besonders bevorzugt ist, bezogen auf das Gesamtgewicht der Formulierung. Es können jedoch bei sehr hoch konzentrierten oder sehr niedrig konzentrierten Formulierungen diese Bereiche überschritten werden.
- Gegebenenfalls kann die Formulierung Hilfsstoffe enthalten; exemplarisch seien genannt Elektrolyte, Konservierungsmittel wie Chloracetamid oder wässrige Formaldehydlösung und Geruchsverbesserer.
- Der Elektrolyt kann Natriumchlorid, Natriumsulfat, Natriumcarbonat oder eines der entsprechenden Kaliumsalze sein oder auch Mischungen der vorgenannten Stoffe. Die Menge an Elektrolyt kann 0,1 bis 25 Gew.%, bezogen auf das Gesamtgewicht der Formulierung, vorzugsweise 0,1 bis 20 Gew.%, betragen.
- Erfindungsgemässe Formulierungen erhält man, indem man den feuchten Filterkuchen oder auch das trockene Pulver eines anionischen optischen Aufhellers, der vorzugsweise mindestens einen Sulfonsäurerest enthält, in einer Menge von 10-60 Gew.% bezogen auf das Gesamtgewicht der Formulierung mit 0,01 - 1 Gew.% anionischem Polysaccharid und Wasser vermischt und homogenisiert.
- Der gewünschte Gehalt an anionischem optischen Aufheller in der Suspension kann entweder durch Zugabe von Wasser, wässrigem Elektrolyt, Suspension oder weiterem trockenen Pulver zu dem feuchten Filterkuchen eingestellt werden. Diese Einstellung kann vor, während oder nach Zusatz des anionischen Polysaccharids vorgenommen werden. Der Anteil des anionischen optischen Aufhellers beträgt zweckmässig 10 bis 60 %, vorzugsweise 15 bis 40 Gew.%, bezogen auf das Gewicht der Suspension.
- Die Suspension wird dann mit dem anionischen Polysaccharid vermischt, bis sie homogen ist.
- Die Formulierung kann in ein Waschmittel eingearbeitet werden, z.B. durch Einfliessenlassen der erforderlichen Menge der Suspension aus einem Behälter in eine Mischvorrichtung, die eine Suspension des Waschmittels bzw. des Detergenz enthält.
- Die vorliegende Erfindung betrifft demzufolge auch ein Verfahren zur Herstellung von Waschmitteln, sowie die danach erhaltenen Waschmittel, dadurch gekennzeichnet, dass man eine Suspension für Waschmittel üblicher Detergentien mit einer erfindungsgemässen Suspension von Aufhellern, vermischt und trocknet. Die erhaltenen Suspensionen werden vorteilhaft getrocknet, indem man sie einem Sprühtrocknungsverfahren unterwirft.
- Weiterhin kann die erfindungsgemässe Aufhellerformulierung zur Herstellung von flüssigen Waschmitteln verwendet werden.
- Die folgenden Beispiele erläutern die Erfindung, ohne sie darauf zu beschränken. Teile sind auf das Gewicht bezogen.
- 0,075 Teile Xanthan
0,2 Teile Chloracetamid
1,3 Teile Natriumsulfat und
5 Teile Natriumchlorid werden in
61 Teilen Wasser gelöst.
Unter Rühren werden in diese Lösung
32,5 Teile feuchter Presskuchen, enthaltend 12 Teile Wasser, 0,5 Teile Natriumchlorid und 20 Teile des optischen Aufhellers - Die weisse Aufhellerformulierung hat eine Viskosität von 108 cP (Haake VT 18, MVII, 22°C, D = 42 sec⁻¹) und bildet nach zweimonatigem Stehen bei -5°C, RT und 40°C keine Ablagerungen.
-
- Die Aufhellerformulierung entspricht in ihren Eigenschaften derjenigen aus Beispiel 1.
- Wie in Beispiel 1 werden
0,1 Teile Chloracetamid
3,0 Teile Natriumchlorid
1,0 Teil Talgfettalkohol mit 11 Mol Ethylenoxid
0,3 Teile Xanthan in
37,5 Teilen Wasser gelöst, mit
58,1 Teilen des wasserfeuchten Filterkuchens, enthaltend 56 Teile Wasser und 44 Teile des optischen Aufhellers - Die Aufhellerformulierung bildet nach mehrmonatigem Stehen bei Raumtemperatur und 40°C keine Ablagerungen.
- Wie in Beispiel 3 werden
0,1 Teile Chloracetamid
0,1 Teile Xanthan
3,0 Teile Natriumchlorid in
5,9 Teilen Wasser gelöst, mit
90,9 Teilen des wasserfeuchten Filterkuchens, enthaltend 56 Teile Wasser und 44 Teile des optischen Aufhellers der Formel (300), versetzt und unter Rühren homogenisiert. - Die Aufhellerformulierung ist bei Raumtemperatur und 40°C lagerstabil.
-
- Die Suspension zeigt nach 3-monatigem Stehen bei Raumtemperatur keine Ablagerungen.
- Wie in Beispiel 3 werden
0,1 Teile Chloracetamid
0,1 Teile Xanthan in
8,9 Teilen Wasser gelöst, mit
90,9 Teilen des wasserfeuchten Filterkuchens, enthaltend 56 Teile Wasser und 44 Teile des optischen Aufhellers der Formel (300), versetzt und unter Rühren homogenisiert. - Die Aufhellerformulierung ist bei Raumtemperatur und 40°C lagerstabil.
