| Popis: | By changing amino acid head group four biobased anionic surfactants were synthesized using 4-vinylguaiacol and methylbromo undecanoate. The synthesized surfactants were characterized by NMR and mass spectrometry analysis. The surface active properties such as surface tension, wetting power, foaming characteristic, emulsion stability, calcium tolerance were studied and compared with those of sodium lauryl sulfate (SLS). Excellent emulsion stabilities and calcium tolerances were observed for the synthesized surfactants. These surfactants show a lower critical micelle concentration as compared to the conventional surfactants. The bulk micellization properties were studied using dynamic light scattering and fluorescence anisotropy technique. The antimicrobial and cytotoxicity studies were also carried out. |
