The present invention comprises dihexyl isophthalate and di(2-ethylhexyl) isophthalate, wherein the dihexyl isophthalate has an alkyl group derived from a hexyl alcohol isomer mixture. If the present invention is applied to a resin, plasticization efficiency, migration loss, and heating loss can be maintained at at least equal levels, and tensile strength and elongation can be improved. La présente invention comprend un isophtalate de dihexyle et un di (2-éthylhexyl) isophtalate, le phtalate d'isophtalate de dihexyle ayant un groupe alkyle dérivé d'un mélange d'isomères d'alcool d'hexyle. Si la présente invention est appliquée à une résine, l'efficacité de plastification, la perte de migration et la perte de chauffage peuvent être maintenues à au moins des niveaux égaux, et la résistance à la traction et l'allongement peuvent être améliorés. 본 발명은 다이헥실 이소프탈레이트 및 다이(2-에틸헥실) 이소프탈레이트를 포함하며, 상기 다이헥실 이소프탈레이트가 헥실 알코올 이성질체 혼합물로부터 유래되는 알킬기를 가지는 것을 특징으로 한다. 이를 수지에 적용할 경우, 가소화 효율, 이행손실 및 가열감량은 동등 이상의 수준을 유지할 수 있고, 인장강도와 신율을 개선할 수 있다.
