Effect of Water Structure on the Formation of Coagels from Ascorbyl-Alkanoates

Lo Nostro, Pierandrea; Ninham, Barry; Fratoni, Laura; Palma, Santiago; Manzo, Ruben; Allemandi, Daniel; Baglioni, Piero


Ascorbyl-alkanoates (ascorbyl-O-CO-(CH2)n-2 CH3, in brief ASCn) behave as anionic surfactants. They form coagels in aqueous dispersions at room temperature. On heating, these hydrated crystalline phases transform into either micellar solutions or gel phases, depending on the hydrophobic chain length. The different phase behavior reflects the interplay between interactions that involve the ionic headgroups and water and those between the hydrophobic chains. Solute-induced modification of water...[Show more]
