## Abstract

The present invention relates to a plasticizer composition, a resin composition and methods of preparing the same, and provides a plasticizer which is environmentally friendly so as to be suitable for use, exhibits excellent transparency and adhesiveness, and can be improved in basic properties such as tensile strength, an elongation rate, hardness and the like when used as a plasticizer for a resin composition, and a resin composition including the same.

## Claims

### Claim 1

A plasticizer composition for a polyvinyl chloride comprising:
a cyclohexane 1,4-diester-based material; and
a dibenzoate-based material,
wherein the plasticizer composition is comprised in an amount of 40 to 130 parts by weight relative to 100 parts by weight of the polyvinyl chloride,
wherein a weight ratio of the cyclohexane 1,4-diester-based material to the dibenzoate-based material included in the plasticizer composition is 90:10 to 50:50,
wherein the cyclohexane 1,4-diester-based material is a single compound or a mixture of two or more selected from the group consisting of butyl(2-ethylhexyl) cyclohexane-1,4- diester (1,4-BEHCH), (2-ethylhexyl) isononyl cyclohexane-1,4-diester (1,4-EHINCH), butyl isononyl cyclohexane-1,4-diester (1,4-BINCH), dibutyl cyclohexane-1,4-diester (1,4-DBCH), diisononyl cyclohexane-1,4-diester (1,4-DINCH) and di(2-ethylhexyl) cyclohexane-1,4-diester (1,4-DEHCH), and
wherein the dibenzoate-based material is one or more selected from the group consisting of diethylene glycol dibenzoate (DEGDB), dipropylene glycol dibenzoate (DPGDB) and triethylene glycol dibenzoate (TEGDB).

### Claim 2 (depends on 1)

A polyvinyl chloride resin composition comprising: the plasticizer composition according to claim 1.
