Abstract: 
Several new multifunctional molecules derived from natural sources such as amino acids and hydroxycinnamicacids were synthesized. They exhibit various activities such as emulsifying, UV-protecting, and radical scavenging, therebyconforming to the latest requirements for cosmetic ingredients. The synthesis comprises only a few steps: (i) the amino acid, theacid groups of which are protected by esterification, is coupled with ferulic or caffeic acid; (ii) the p-hydroxyl group of thecinnamic derivative reacts with dodecyl bromide in the presence of potassium carbonate (the resulting compounds are highlylipophilic and tested as water/oil (W/O) emulsifiers); (iii) these molecules, by deprotonating the acid groups of the amino acids,with successive salification, are more hydrophilic, with stronger O/W emulsifying properties. The new multifunctional surfactantsmight prove useful for the treatment of multiple skin conditions, including loss of cellular antioxidants, damage from free radicals,damage from UV, and others.
