Abstract:
Two surfactants with one hydrophilic head group (lauroyl hydroxyproline and palmitoyl
hydroxyproline) and a bolaamphiphilic surfactant, with two hydrophilic head groups (1,12-
dodecanedioyl diglycylglycine) were synthesized using a method with reduced environmental
impact. The high conversions in useful product were sustained by FTIR analysis. It was
evaluated the surface activity of aqueous solutions of surfactants’ sodium salts and it was
demonstrated a significant reduction in the surface tension compared to distilled water.
Synthesized surfactants can be a viable alternative for the petrochemical products.
