Micelle structures in unequal mixtures of amino-acid surfactants

Abstract: In a previous proposal we started to study the micellar structures formed from biodegradable surfactants synthesised using amino acids as the headgroups. The aim of this work is to utilize a waste grain residue from brewing which is rich in proline, glycine and glutamine as the source for polar surfactant headgroups, ideally without first separating these compounds from the mixture. We are therefore interested in the behaviour of mixed micelles formed from these surfactants, and began investigations using 1:1 molar ratio mixtures of these species. This provided interesting results, where micelle shape suggests nonideal mixing even at concentrations far above the CMC. Thus here we would like to pursue investigations on this system at 3:1 molar ratios for the 3 different amino acid headgroups and C12, C14 and C16 tail lengths.
