Disclosed are compositions including up to 20 wt % of a paraffin inhibiting polymer and a non-polymeric ester compound, wherein the compositions flow at a temperature between about 0° C. and −40° C., or between about −20° C. and −40° C. The non-polymeric ester compounds are liquids at 20° C. and atmospheric pressure, and have boiling points over 100° C., in many cases over 200° C. The compositions are useful to inhibit paraffin deposition during petroleum recovery, refining, storing, and transporting under field conditions, wherein the concentrates are pumpable and pourable, do not precipitate, and do not exhibit high pressure buildup inside enclosed containers at temperatures as low as −40° C. and as high as 60° C.
