Abstract

GREEN SYNTHESIS, CHARACTERIZATION, AND EVALUATION OF FATTY ACID ESTERS AS NATURAL EMULSIFIERS IN COSMETIC FORMULATIONS

*Seba Nassif, Ola Albereny

ABSTRACT

The synthesis of fatty esters is an important area in industrial chemistry due to their increasing use in cosmetic formulations as natural emulsifiers. Their surface-active properties enable the formation of stable emulsions, enhancing product stability and shelf life. In this study, an eco-friendly Fischer esterification method was employed to synthesize fatty esters from myristic acid and oleic acid using 1-propanol, catalyzed by the recyclable heterogeneous acid catalyst Amberlyst-15. The formation of propyl myristate and propyl oleate was confirmed by FTIR and ^1H-NMR spectroscopy, with yields of 72% and 69%, respectively. The emulsifying behavior of the synthesized esters was evaluated through hydrophilic–lipophilic balance (HLB) values, which indicated their lipophilic nature. Application tests in a cosmetic cream formulation demonstrated that blending both esters resulted in improved texture, consistency, and overall formulation performance compared to the individual esters.
