Alkanolamide free fuel additives
First Claim
1. A fuel composition which is substantially free of alkanolamides, comprising at least 95% by volume of hydrocarbon-based fuel and from 0.1 to 5% by volume of an additive selected from the groups consisting of:
- (a) optionally alkoxylated linear or branched saturated or unsaturated C8-24 monoalcohols, comprising 0 to 20 mol of ethylene oxide or 1 to 5 mol of propylene oxide per mol of alcohol;
or (b) C2-6 polyols, optionally partially esterified with C12-24 fatty acids;
or (c) alkoxylated C12-24 fatty acids having 4 to 20 mol of ethylene oxide per mol of fatty acid;
or (d) ethoxylated dimeric fatty acids.

Abstract
There is described a fuel composition which is substantially free of alkanolamides, containing at least 95 % by volume of a hydrocarbon-based fuel and from 0.1 to 5 % by volume of an additive selected from the groups consisting of: a) the optionally alkoxylated linear or branched saturated or unsaturated monoalcolhols having 8 to 24 C atoms, containing zero or 1 to 20 mol of ethylene oxide and/or 1 to 5 mol of propylene oxide per mol of alcohol, or b) the polyols having 2 to 6 carbon atoms, optionally partially esterified with fatty acids having 12 to 24 carbon atoms, or c) the alkoxylated fatty acids having 12 to 24 carbon atoms and 4 to 20 mol of ethylene oxide per mol of fatty acid, or d) the ethoxylated dimeric fatty acids.
