High internal phase emulsions (HIPEs) with an internal phase fraction of 84 vol % were prepared using carboxymethyl cellulose (CMC) and palm kernel oil ethoxylates (SOE-N-60) as a dual emulsifier. Effects of the oil-phase volume fraction, CMC concentration, and SOE-N-60 concentration on oil-in-water HIPEs stability were systematically studied by a Mastersizer 2000 instrument, Lx POL polarizing microscope, rheometer, etc. The bioavailability of tea tree oil can be effectively protected using HIPEs as a delivery system. The experimental results showed that, with the increase of the concentrations of CMC and SOE-N-60, the droplet size of HIPEs gradually decreases and the HIPEs showed good static stability. In addition, it was observed by scanning electron microscopy that the polyHIPEs materials using HIPEs stabilized by different SOE-N-60 and CMC concentrations as templates had different structures. Moreover, the synergism between CMC and SOE-N-60 surfactants plays a significant role in the preparation and stability of HIPEs.

羧甲基纤维素钠和棕榈仁油乙氧基化物作为精油输送系统协同稳定的高内相乳液
使用羧甲基纤维素（CMC）和棕榈仁油乙氧基化物（SOE-N-60）作为双乳化剂，制备了内相分数为84 vol％的高内相乳液（HIPE）。通过Mastersizer 2000仪器，Lx POL偏振镜，流变仪等系统研究了油相体积分数，CMC浓度和SOE-N-60浓度对水包油HIPE稳定性的影响。茶树的生物利用度使用HIPE作为输送系统可以有效地保护石油。实验结果表明，随着CMC和SOE-N-60浓度的增加，HIPEs的液滴尺寸逐渐减小，并且HIPEs具有良好的静态稳定性。此外，通过扫描电子显微镜观察到，使用通过不同SOE-N-60和CMC浓度稳定的HIPE作为模板的polyHIPEs材料具有不同的结构。此外，CMC和SOE-N-60表面活性剂之间的协同作用在HIPE的制备和稳定性中起着重要作用。
