In this work, karanja oil has been epoxidized and further used as biobased plasticizer to improve some properties of poly (lactic acid) (PLA). The use of epoxidized karanja oil (EKO) has been studied because karanja oil is used in organic farming as an insecticide and generating an epoxidation of the oil can act as a PLA plasticizer. Melt extrusion was used to plasticize PLA with different EKO amounts in the 0–10 wt%. The formulations with EKO decrease the glass transition temperature as the EKO content increases and, in addition, generates an increase in elongation at break. Plasticizer saturation is observed by scanning electron microscopy (SEM) above 5% of EKO. PLA formulation with 5 wt% shows an optimal balance between the improvement of the fragility of the material, improving the elongation at breakage by 77%, using a relatively small concentration of plasticizer. Moreover, all materials were disintegrated under composting conditions at laboratory scale level.

在这项工作中，魔芋油已被环氧化并进一步用作生物基增塑剂，以改善聚乳酸（PLA）的某些性能。已经研究了使用环氧化的魔芋油（EKO），因为在有机农业中使用了魔芋油作为杀虫剂，并且产生的环氧化油可以用作PLA增塑剂。熔融挤出用于增塑0至10 wt％的具有不同EKO量的PLA。随着EKO含量的增加，具有EKO的配方降低了玻璃化转变温度，此外，断裂伸长率也增加了。通过高于EKO的5％的扫描电子显微镜（SEM）观察到增塑剂饱和。含量为5 wt％的PLA配方在改善材料的脆性和将断裂伸长率提高77％之间显示了最佳的平衡，使用相对较小浓度的增塑剂。此外，所有材料都在堆肥条件下在实验室规模下分解。
