Biocompatible and biodegradable molecules of Phenyl- and Tyrosine-glycerol ether surfactants are good candidates for eco-friendly cosmetic emulsions. Both molecules have a hydrophobic alkyl chain with 12 carbon atoms, but different amino acids in the hydrophilic head: phenylalanine (PhGE 12 ) and tyrosine (TyrGE 12 ). This study reports on the activity of liquid/liquid interfaces with...
Dynamic surface tension and dilatational viscoelasticity data are presented for aqueous solutions of novel nonconventional eco-friendly phenylalanine glycerol ether surfactants, with 12 carbon atoms in the hydrophobic alkyl chain, PhGE12. Adsorption kinetics is studied in a broad range of concentrations and for time scales spanning from several milliseconds to several hours employing maximum bubble...
Due to the increasing demand for environmentally friendly surfactants, a novel non-conventional glycerol ether surfactant with 12 carbon atoms in the hydrophobic alkyl chain and the amino acid tyrosine in the hydrophilic head (TyrGE12) is synthesized. Measurements of dynamic surface tension by maximum bubble pressure tensiometry and drop profile tensiometry are carried out for alkali aqueous solutions...
