Abstract

Polysorbate 80 and sodium lauryl ether sulphate mixtures are often used in personal care products especially in shampoo formulations. In this paper, the combined effect of sodium lauryl ether sulphate and salts (Na2SO4, NaCl, CaCl2) and sodium lauryl ether sulphate and alcohols having different chain length on the cloud point of polysorbate 80 has been studied. The cloud point of a nonionic surfactant is influenced by the presence of additives. In the current system, a rise in the cloud point of polysorbate 80 was observed in the presence of ionic surfactant, sodium lauryl ether sulphate (0.010–0.050 mM) which is interpreted as increase in the surface charge of micelle. The cloud point of the sodium lauryl ether sulphate-polysorbate 80 mixture decreased with the addition of inorganic salts. The presence of short chain alcohols (C1–C3) was found to increase the cloud point of polysorbate 80-sodium lauryl ether sulphate mixtures whereas, long chain alcohols (C4, C5) were found to decrease the cloud point of polysorbate 80-sodium lauryl ether sulphate mixtures depending on their solubility in water.

Kurzfassung

Mischungen aus Polysorbat 80 und Natriumlaurylethersulfat werden häufig in Körperpflegeprodukten, insbesondere in Shampooformulierungen, verwendet. In dieser Arbeit wurde die kombinierte Wirkung von Natriumlaurylethersulfat und Salzen (Na2SO4, NaCl, CaCl2) und von Natriumlaurylethersulfat und Alkoholen mit unterschiedlicher Kettenlänge auf den Trübungspunkt von Polysorbat 80 untersucht. Der Trübungspunkt eines nichtionischen Tensids wird durch die Anwesenheit von Additiven beeinflusst. In dem hier untersuchten System wurde ein Anstieg des Trübungspunktes von Polysorbat 80 in Gegenwart vom ionischen Tensid Natriumlaurylethersulfat (0,010 bis 0,050 mM) beobachtet, was als Zunahme der Oberflächenladung von Mizellen interpretiert wird. Der Trübungspunkt von der Mischung aus Natriumlaurylethersulfat und Polysorbat 80 nahm unter Zugabe von anorganischen Salzen ab. Es wurde gefunden, dass die Anwesenheit von kurzkettigen Alkoholen (C1–C3) den Trübungspunkt von Polysorbat 80 – Natriumlaurylethersulfatmischungen erhöht, wohingegen langkettige Alkohole (C4, C5) den Trübungspunkt von Mischungen aus Polysorbat 80-Natriumlaurylethersulfat in Abhängigkeit von ihrer Wasserlöslichkeit verringern.
