1. A plasticizer composition comprising a cyclohexane 1,4-diester-based material comprising one or more cyclohexane 1,4-diesters, wherein each of two alkyl groups combined with two ester groups of the one or more cyclohexane 1,4-diester has a carbon number of 8 to 12; and a trimellitate-based material comprising a compound represented by the following Formula 1:

OG Complex Work Unit Chemistry
wherein in Formula 1, R1 to R3 are each independently an alkyl group of 8 to 12 carbon atoms, and
wherein a weight ratio of the cyclohexane 1,4-diester-based material to the trimellitate-based material is 90:10 to 10:90,
the plasticizer composition further comprises two additional 1,4-diester cyclohexanes, each of which are different from the cyclohexane 1,4-diester having each of two alkyl groups having a carbon number of 8 to 12 combined with two ester groups,
the plasticizer composition comprises 3.0 to 99.0 mol % of the cyclohexane 1,4-diester having each of two alkyl groups having a carbon number of 8 to 12 combined with two ester groups, and
the plasticizer composition comprises 0.5 to 96.5 mol % of each of the two additional 1,4-diester cyclohexanes.
