Cindy Yi: A Switchable Solution

Their ability to associate with both hydrophobic and hydrophilic compounds contributes to their widespread use in various settings. Due to their ubiquity in commercial and consumer products, the end-of-life of surfactants has become a significant environmental issue.

While most surfactant have hydrophobic tails that are biodegradable, most surfactant head-groups are petrochemical-derived and not designed for biodegradation, persisting in the environment. Thus, in modern surfactant design, biodegradability is a principal concern.<br><br>Switchable surfactants have alterable physicochemical properties based on factors such as pH, enabling their separation from solvent mixtures and facilitating their recovery.
