Plasticizer composition and resin composition including the same

A plasticizer composition, comprising:

• a terephthalate-based material comprising a mixture of dibutyl terephthalate, butyl(2-ethylhexyl) terephthalate, di(2-ethylhexyl) terephthalate, and a terephthalate represented by the following Formula 1;
• and
• a triethylene glycol diester-based material comprising a mixture of triethylene glycol bis(2-ethylhexanoate), (2-ethylhexanoyloxy) triethylene glycol benzoate and triethylene glycol dibenzoate,
• wherein, based on 100 parts by weight of a mixture of the di(2-ethylhexyl) terephthalate and the terephthalate represented by the following Formula 1, the di(2-ethylhexyl) terephthalate is 99.0 parts by weight or more, and the terephthalate represented by the following Formula 1 is less than 1.0 part by weight:
• wherein in Formula 1, R1 is a linear or branched alkyl group of 1 to 13 carbon atoms, with the proviso that R1 is not a 2-ethylhexyl group, and
• wherein a weight ratio of the terephthalate-based material and the triethylene glycol diester-based material is 90:10 to 10:90.
