Description

Vitamin C-based alkanoyl-6-O-ascorbic acid esters, ASCn, are a class of surfactants, interesting both on account of their phase behaviour, and of the properties of the supramolecular assemblies they form. When dispersed in water at room, or lower, temperatures above ca. 5% w/w concentration, they form coagels. At higher temperatures, the microstructure changes to micellar solutions for surfactants of low hydrocarbon chain length n. The longer chained systems form gel phases. The transition...[Show more]
