Enhanced Efficiency of Anionic Guerbet-Type Amino Acid Surfactants.

ABSTRACT: This study investigates the surfactant properties and efficiency of linear and Guerbet-type amino acid surfactants. Utilizing a Wilhelmy plate method, we assessed the colloidal efficiency of these surfactants, with the lowest observed critical micelle concentration at 0.046 mmol L^-1, significantly reducing surface tension to as low as 25.1 mN·m^-1. Furthermore, the self-diffusion coefficients of the various surfactants have been determined through ¹H pulsed-field gradient nuclear magnetic resonance diffusion-ordered spectroscopy. The self-diffusion coefficients are linked to the surface tension reduction as a function of concentration to determine the characteristic time scale of diffusion. In this work, the characteristic time scale of diffusion of a series
