description Disclosed are compositions including up to 20 wt% of a paraffin inhibiting polymer, a refined petroleum distillate and one or more low LogP molecules, wherein the compositions are stable and flow at a temperature between about 0 °C and -40 °C, in many cases between about -20 °C and -40 °C. The low LogP molecules are non-polymeric, have a LogP of less than 1, are liquids at 20 °C (1 arm), and have boiling points over 60 °C, in many cases over 100 °C. The compositions are useful paraffin inhibitor concentrates for use in the petroleum industry wherein the concentrates are stable, pumpable, and pourable at temperatures as low as -40 °C and as high as 60 °C. L'invention se rapporte à des compositions comprenant jusqu'à 20% en poids d'un polymère inhibiteur de paraffine, un distillat de pétrole raffiné et une ou plusieurs molécules à LogP faible, les compositions étant stables et fluides à une température comprise entre environ 0°C et -40°C et, souvent, entre environ -20°C et -40°C. Les molécules à LogP faible sont non polymères, présentent un LogP inférieur à 1, sont liquides à 20°C (1 atm) et présentent des points d'ébullition supérieurs à 60°C, souvent, supérieurs à 100°C. Les compositions sont utiles en tant que concentrés inhibiteurs de paraffine pour une utilisation dans l'industrie pétrolière, les concentrés étant stables, pompables et aptes à l'écoulement à des températures allant de -40 à 60°C.
