Effect of Headgroup Chirality in Nanoassemblies. 2. Thermal Behavior of Vitamin C-Based Surfactants
L-Ascorbic and D-isoascorbic acids are epimers, and their alkanoyl-esters are surfactant-like in water. These ascorbic acid derivatives retain the same stereogenic configurations of the parent molecules. That circumstance strongly affects their physicochemical properties, both in the solid and in the dispersed states. The thermal behavior of 6-O-L-ascorbyl-dodecanoate (L-ASC12), of 6-0-D-isoascorbyl-dodecanoate (D-ASC12), and of their mixtures was investigated through DSC, XRD, and FTIR...[Show more]
