1. A composition comprising at least one fatty acid or derivative thereof and at least one low temperature stabilizer in an amount ranging from 0.01 wt % to 25 wt %, based upon the total weight of the composition, selected from the group consisting of ester-terminated polyamides, tertiary-amide-terminated polyamides, ester-terminated polyester-amides, tertiary amide-terminated polyester-amides, polyalkyleneoxy-terminated polyamides, and polyether-polyamides,
wherein the fatty acid or derivative thereof and the at least one low temperature stabilizer are contacted by mixing or blending while applying heat at a temperature higher or lower than the melting or softening point of the at least one low temperature stabilizer, wherein the addition of the low temperature stabilizer does not cause visually observable gelling or precipitation when in contact with the fatty acid and the mixture of the low temperature stabilizer and the fatty acid is physically indistinct from the fatty acid, wherein the composition has improved low temperature stability compared to a composition that does not contain said at least one low temperature stabilizer, wherein the improvement is at least a 1% improvement in low temperature stability as measured by at least one low temperature stability performance factor selected from the group consisting of differential scanning calorimetry event, long-term storability, cloud point, pour point, and cold flow plugging point, and wherein said composition is one of the group consisting of fuels, fuel additives, fuel blend component, lubricity improvers, friction modifiers, components of fuel additive packages, and any combinations thereof. |
