采用直接面间缩聚（水包油）法制备了直径为~ 5µm的含聚酰胺的荷荷巴油微胶囊。通过扫描电镜观察了配方和工艺参数对微胶囊特性的定性影响。形态学分析表明，外膜致密性取决于水溶性多胺和油溶性酸性聚氯乙烯的化学性质：1,6-六亚甲二胺（HMDA）和对苯二甲酰二氯（TDC）有利于产生光滑致密的表面。在分散步骤中使用超声波照射以进一步减小微胶囊的尺寸也进行了评估。
Jojoba oil containing polyamide microcapsules having diameter of ∼5 µm were prepared by inter-facial polycondensation by direct method (oil-in-water). Qualitative effects of both the formulation and the process parameters on microcapsules characteristics were investigated by SEM observations. Morphological analysis showed the dependence of the external membrane compactness on the chemical nature of the water-soluble polyamine and the oil-soluble acid polychloride: 1,6-hexamethylenediamine (HMDA) and terephthaloyl dichloride (TDC) were found to favour the production of smooth and dense surfaces. The use of ultrasonic irradiations during the dispersion step to get a further reduction of microcapsules size was also evaluated.
