A comparative study on the interface tension and interface dilational rheological properties of three sodium -acyl aromatic amino acid surfactants.

Interface dilational rheology is useful for understanding and exploring the role of interface phenomena. However, relatively few studies have been conducted on the interface dilational rheological properties of -acyl aromatic amino acid surfactants. Herein, surface tension and the dynamic interface tension and dilational rheological properties of three surfactants, namely, sodium -lauroyl phenylalaninate (SLP), sodium -lauroyl tyrosinate (SLTy), and sodium -lauroyl citrate (SLTr) were investigated.
