A dialkylanilino-cyclohexane compound useful as an antioxidant has the following formula I or formula II:
wherein Ar
1
and Ar
2
can be the same or different and each is an alkylaromatic group; each of R
1
, R
2
, R
3
, and R
4
is independently selected from hydrogen or CR
7
R
8
; each of R
5
, R
6
, and R
7
is independently selected from hydrogen and a substituted or unsubstituted C
1
to C
32
hydrocarbyl group; and each R
8
is independently selected from hydrogen and a C
1
to C
2
alkyl group, provided that when, each of R
1
and R
2
is CR
7
R
8
and each such R
8
is other than hydrogen, R
1
and R
2
may be joined to form a five or six-membered ring, and provided further that when, each of R
3
and R
4
is an adjacent CR
7
R
8
and each such R
8
is other than hydrogen, R
3
and R
4
may be joined to form a five or six-membered ring.
