    The microcapsules of chitosan/sodium alginate/porous starch-tea tree essential oil (CS/SA/PSTTEO) were successfully prepared by polyelectrolyte complex coacervation method with PS as the core material carrier to adsorb TTEO, SA-CS as the wall material, and glutaraldehyde (GA) as crosslinker. The preparation conditions were optimized as follows. The optimum ratio of PS to TTEO was 0. 88 : 1, the concentration of SA was 3. 0%, the concentration of CS was 3. 0%, the concentration of GA was 2. 0%, and the reaction temperature was 30 degrees C. The formation, properties and release behaviors of CS/SA/PS-TTEO microcapsules were analyzed by scanning electron microscope (TEM), thermogravimetry (TGA), Fourier transform infrared spectroscopy (FT-IR), stability test and release rate experiments. The results showed that in the open system, cumulative release rate of CS/SA/PS-TTEO microcapsules for 14 days was 15.77%, and the lowest release rate 14 a single day was 0. 20%. In the closed system, the cumulative release rate of 14 days was 7. 37%, and the release rate tended to be stable in about 10 days, with the lowest release rate of 0.04% in a single day, which proved that CS/SA/PS-TTEO microcapsules had the ability of slow release. CS/SA/PS-TTEO microcapsule was stable at -18 degrees C to 50 degrees C in the commonly used cosmetic solvent, and this property was beneficial to improve the stability of the storage and transport of cosmetics containing TTEO.
