1. A plasticizer composition, comprising:
70 to 99 wt % of a first plasticizer comprising a terephthalate-based material and a citrate-based material; and
1 to 30 wt % of a second plasticizer comprising an epoxidized alkyl ester composition containing one or more compounds represented by Formula 1:

OG Complex Work Unit Chemistry
wherein in Formula 1, R1 is an alkyl group of 8 to 20 carbon atoms containing one or more epoxy substituents, and R2 is selected from the group consisting of an isononyl group and a 2-propylheptyl group,
wherein the terephthalate-based material is one or more selected from the group consisting of di(2-ethylhexyl) terephthalate (DEHTP) and diisononyl terephthalate (DINTP),
wherein the citrate-based material is one or more selected from the group consisting of tributyl citrate (TBC) and tripentyl citrate (TPC),
wherein a weight ratio of the first plasticizer and the second plasticizer is 95:5 to 70:30, and
