The present invention provides for a rheology control agent that includes a following compound represented by the following formula:
wherein A, B, C and D equal CH
2
, CHR, NH, or O, and A, B, C and D may be the same or different and at least one of A and B equals NH and at least one of C and D equals NH; and wherein R
1
, R
2
, and R
3
may be the same or different and represent a linear, branched, hyper-branched, or dendritic ether, polyether or hydrocarbon based chain, optionally forming at least one carbon-based ring, being saturated or unsaturated and R
2
represents linear or branched alkylenes, ethers, polyethers, or polyester linkages and at least one of R
1
, R
2
, and R
3
comprises an ester group or an amide group which is branched off from the main chain; excluded from Formula (1) is a compound wherein R
2
is CH

—CH
2
—CH
2
—CH(C(O)OCH
3
), A, B, C, and D are equal to NH and R
1
and R
