1. A plasticizer composition comprising:
greater than 40 weight percent (wt %) of a compound of formula I:

OG Complex Work Unit Chemistry
20-30 wt % of a compound of formula II:

OG Complex Work Unit Chemistry
and
20-40 wt % of a compound of formula III:

OG Complex Work Unit Chemistry
wherein:
each R1 is independently an unbranched or branched (C1-9)alkyl;
each R2 is independently an unbranched or branched (C1-12)alkyl; and
each n is independently 1, 2 or 3,
wherein the wt % is determined based on the total weight of the plasticizer composition.
