Abstract: This study aims to determine the effect of adding Sodium Dodecyl Sulfate (SDS) as a surfactant in encapsulating citronella oil using alginate/carrageenan (Alg/Car). The functional groups of microparticles were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and morphologically by Scanning Electron Microscope (SEM) analysis. The FTIR results show that the SDS causes a new peak spectrum to be formed at 1110 cm-1, due to stretching of the S=O sulfate groups from SDS. SEM analysis showed that the addition of SDS resulted in beads having a coarse structure with a multi-void surface. The encapsulation e?ciency of Citronella in SDS/Alg-Carr beads was found signi?cantly higher (95.825%) compared to that of beads without SDS. The addition of SDS increased the antioxidant activity of citronella-loaded alginate-carrageenan beads. The release study showed controlled release in an acidic solution (pH 1.2) and a higher release rate at pH 6.8 (neutral). Alg/Car/Citronella beads modified with SDS can improve their properties and acid resistance, which makes them suitable for numerous applications.
