Abstract
In this work, we have investigated the washing performance of sodium oxalate-based detergents containing different enzymes (protease, lipase and cellulase). The results show that sodium oxalate-based detergents with enzymes have a better washing performance than formulations containing the conventional builder STPP and zeolite 4A. For sodium oxalate-based with protease, the amount of sodium oxalate and protease have a significant effect on the detergency. Lipase can improve detergency of sodium oxalate-based detergents after “first washing” in the presence of different anionic surfactant (LAS, MES and AES). For cellulase, only sodium oxalate in the presence of LAS has a detergency increase.
Kurzfassung
In dieser Arbeit haben wir die Waschleistung von Waschmittelmittelformulierungen auf Natriumoxalatbasis untersucht, die verschiedene Enzyme (Protease, Lipase und Cellulase) enthalten. Die Ergebnisse zeigen, dass die Waschmittelformulierungen auf Natriumoxalatbasis mit Enzymen eine bessere Waschleistung aufweisen als enzymhaltige Formulierungen auf Basis von konventionellen Buildern wie STPP und Zeolith 4A. Waschmittelformulierungen auf Natriumoxalatbasis, die Protease enthalten, hat die Menge an Natriumoxalat und an Protease einen signifikanten Einfluss auf die Waschkraft. Lipase kann die Waschkraft von Waschmittelformulierungen auf Natriumoxalatbasis verbessern, nachdem sie unter verschiedenen anionischen Tensiden (LAS, MES und AES) “gewaschen” wurden. Mit Cellulase hat nur Natriumoxalat mit LAS eine Waschkraftsteigerung.
