Abstract

   

A two-step approach, which included oil-in-water emulsification and spray drying, was employed to encapsulate citronella oil in acacia gum microcapsules. Crucial parameters that affect the quality of spray-dried citronella oil microcapsules were simultaneously evaluated. A central composite design was utilized to determine the optimum processing conditions as a function of various parameters. The optimal microencapsulation conditions consisted of an acacia gum percentage, citronella oil percentage and inlet air temperature of 14% w/w, 26% w/w of the wall material and 150 °C, respectively. Moreover, prolonged volatility and reduced irritation properties of citronella oil in the microcapsules were demonstrated. Scanning electron microscopy revealed that the microcapsules can be easily impregnated onto a nonwoven fabric. The resulting microcapsules not only have the potential to offer prolonged volatility of the odor with reduced irritation but also are a candidate for the further development of citronella essential oil-based cosmetic textiles.
