A comparative study was carried out on the chemical, structural and thermal properties of candelilla wax from four wax-producing communities in Mexico, which was obtained by two extraction processes, the conventional one using sulfuric acid (SA) and an eco-friendly alternative process using citric acid (CA) as the extracting agent. The waxes were analyzed by basic chemistry (acidity, saponification, ester indexes, and others), color, Fourier transform infrared spectroscopy (FTIR), Raman micro-spectroscopy, X-ray diffraction (XRD), differential scanning calorimetry (DSC), and hardness and brittleness measurements. The waxes obtained by the environmentally friendly process showed differences in their physicochemical properties when compared to waxes from the conventional process. In addition, they showed some improvements, such as lighter shades and harder waxes, suggesting that the new environmentally friendly process is a viable option.
对来自墨西哥四个产蜡社区的两种提取方法（传统的硫酸法（SA）和环保的柠檬酸法（CA））提取的坎地里拉蜡的化学、结构和热性能进行了比较研究。通过基础化学分析（酸度、皂化值、酯指数等）、颜色、傅里叶变换红外光谱（FTIR）、拉曼微光谱、X 射线衍射（XRD）、差示扫描量热法（DSC）和硬度和脆性测量来分析蜡。与传统工艺的蜡相比，环保工艺获得的蜡在理化性质上存在差异。此外，它们还表现出一些改进，例如颜色更浅、蜡更硬，这表明新的环保工艺是一种可行的选择。
