Abstract
The present invention relates to a plasticizer composition and a resin composition including the same. The compositions comprise a terephthalate-based material, a dibenzoate-based material, and a citrate. The compositions and methods have a weight ratio of the terephthalate-based material to the benzoate-based material of 99:1 to 1:99. The citrate-based material is included at 1 to 80 parts by weight with respect to 100 parts by weight of the total weight of the terephthalate-based material and the dibenzoate-based material.
