Preparation and Physiochemical Properties of Disodium Lauryl Glucoside Sulfosuccinate

摘要

A new synthetic route to a mild surfactant disodium lauryl glucoside sulfosuccinate (AG-SS) containing two hydrophilic groups is described and its measured physicochemical properties reported. AG-SS was synthesized from lauryl glucoside reacted with maleic acid anhydride, and then sulfonated with sodium sulfite. The structure and composition of the product were defined by Fourier transform infrared spectroscopy and liquid chro-matography-mass spectrometry. The surface activity measurement showed that the critical micelle concentration (CMC) and that the surface tension at CMC (γ_(CMC)) of AG-SS were 2.59 x 10~(-4) mol/L and 35.21 mN/m at 25 °C, respectively. AG-SS exhibited excellent water solubility eliminating the disadvantage of lauryl glucoside; its foaming ability was also remarkable.
