Abstract:

Two amino acid-based Gemini surfactants derived fromcystine, sodium N,N’-di(4-n-butyloxycinnamoly)-L-cystine (SDBCC) and sodium N,N’-didecamino L-cystine (SDDC), were synthesized. Their surface activity and aggregation properties were also investigated by equilibrium surface tension measurements, dynamic light scattering (DLS), and transmission electron microscopy (TEM).

Key words: Gemini surfactant, Surface activity, Vesicle, Aggregation behavior
