Abstract

Two mixture solutions consisting of sulfo-betain zwitterionic surfactant and alcohol ether sulfate (AES) are designed and prepared; their surface tensions and critical micelle concentrations (cmc) with different mole ratio are determined by surface tensions scanning. With pseudo-regular solution theory, the interaction parameters in the micelle (βm) and at the surface (βσ) are evaluated. As the results reveal two different mixtures of sulfobetaine-(I)/AES and sulfobetaine-(II)/AES show good synergistic behaves in both surface tension reduction effectiveness/efficiency and mixed micelle formation at all mole fractions investigated.

Kurzfassung

Zwei Mischungen aus zwitterionischen Sulfobetaintensiden und Alkoholethersulfaten (AES) wurden entworfen und hergestellt. Ihre Oberflächenspannungen und kritische Mizellbildungskonzentrationen (cmc) bei unterschiedlichen Molverhältnissen wurden mit einem Grenzflächenspannungsscan bestimmt. Mit der Pseudo-regulären Lösungstheorie wurden die Wechselwirkungsparameter in der Mizelle (βm) und an der Grenzfläche (βσ) berechnet. Die Ergebnisse zeigen, dass zwei unterschiedliche Mischungen aus Sulfobetain-(I)/AES und Sulfobetain-(II)/AES gute synergistische Verhaltensweisen aufweisen sowohl bei dem Vermögen, die Oberflächenspannung zu reduzieren, als auch bei der Bildung von Mischmizellen mit allen untersuchten Molenbrüchen.
