Abstract
Description
Die Paste enthält mindestens eine wässrige Base, wobei Alkalimetallhydroxide wie Natrium-, Kalium- und Lithiumhydroxid, Erdalkalimetalloxide und -hydroxide wie Magnesiumoxid, Magnesium-hydroxid, Calciumoxid und Calciumhydroxid, Ammoniak, Mono-, Di- und Tri-C2-4-Alkanolamine, beispielsweise Mono-, Di- und Triethanolamin sowie primäre, sekundäre oder tertiäre C1-4-Alkylamine sowie Glucamine oder Gemische davon in den Mengen von 0,01 bis 0,3 Gew.-%, bezogen auf den Tensidgehalt in Betracht kommen. Bevorzugt ist ein Alkalihydroxyd, besonders bevorzugt Natrium- oder Kaliumhydroxid. Aus Stabilitätsgründen darf der pH-Wert der Paste nicht unter 8,5 sinken. Da aus Gründen der Viskosität jedoch eine möglichst geringe Konzentration an Base erwünscht ist, enthält die Paste bevorzugt möglichst geringe Mengen der Base. Bevorzugt sind pH-Werte von 8,5 bis 14, besonders bevorzugt 9 bis 13. Die Viskosität der Paste beträgt bei einer Temperatur von 70 °C zwischen 8000 und 20000 mPas*s, bevorzugt 12000 bis 16000 mPas*s, gemessen nach Brookfield (RVT, 20 U/min, Spindel 6).
In einer bevorzugten Ausführungsform enthalten die erfindungsgemäßen Tensidpasten, mit Ausnahme der in den Ausgangsstoffen üblicherweise enthaltenen Verunreinigungen, keine weiteren Inhaltsstoffe.
Die Fettalkoholsulfate der vorliegenden Erfindung leiten sich von Fettalkoholen mit 12 bis 18 Kohlenstoffatomen ab. Typische Beispiele hierfür sind Laurylalkohol, Myristylalkohol, Cetylalkohol und Stearylalkohol. Die Fettalkoholsulfate können sich auch von technischen Alkoholgemischen ableiten, wie sie z.B. bei der Hydrierung von technischen Fettsäureestergemischen natürlicher Herkunft oder von Aldehyden aus der Roelen'schen Oxosynthese anfallen. Bevorzugt sind hierbei Fettalkoholsulfate auf der Basis technischer Kokos- oder hydrierter Palmkernschnitte.
Üblicherweise wird die Sulfatierung bei Temperaturen von 30 bis 70 °C durchgeführt. Im Hinblick auf die Viskosität der Einsatzstoffe einerseits und die Farbqualität der resultierenden Sulfatierungsprodukte andererseits, hat es sich als optimal erwiesen, die Reaktion in einem Temperaturbereich von 40 bis 60 °C durchzuführen.
Die bei der Sulfatierung anfallenden sauren Sulfierprodukte werden in wässrige Basen eingerührt, neutralisiert und auf einen pH- Wert von mindestens 8.5 eingestellt. Als Basen für die Neutralisation kommen Alkalimetallhydroxide wie Natrium-, Kalium- und Lithiumhydroxid, Erdalkalimetalloxide und -hydroxide wie Magnesiumoxid, Magnesiumhydroxid, Calciumoxid und Calciumhydroxid, Ammoniak, Mono-, Di- und Tri-C2-4-Alkanolamine, beispielsweise Mono-, Di- und Triethanolamin sowie primäre, sekundäre oder tertiäre C1-4-Alkylamine sowie Glucamine oder Gemische davon in Betracht. Bevorzugt ist ein Alkalihydroxyd, besonders bevorzugt Natrium- oder Kaliumhydroxid.
Die Sulfatierungsprodukte können nach Neutralisation in an sich bekannter Weise durch Zusatz von Wasserstoffperoxid- oder Natriumhypochloritlösung gebleicht werden. Der pH-Wert der Lösungen kann unter Verwendung geeigneter Puffermittel, z. B. mit Natriumphosphat oder Citronensäure konstant gehalten werden. Zur Stabilisierung gegen Bakterienbefall empfiehlt sich ferner eine Konservierung, z. B. mit Formaldehydlösung, p-Hydroxybenzoat, Sorbinsäure oder anderen bekannten Konservierungsstoffen.
