[R5-L-N(R1)(R2)(R3)]+X− (1)
wherein
each of R1 and R2 is independently an alkyl group having from 1 to 5 carbon atoms; or wherein the nitrogen atom and the R1 and R2 groups together form a substituted or unsubstituted heterocyclic group;

wherein
R1 is an alkyl or alkenyl group having from 7 to 21 carbon atoms,
R2 and R3 are each independently an alkyl group containing 1 to 10 carbon atoms, or together form an optionally substituted ring having 5 to 10 ring atoms, wherein the ring may carry up to 3 substituents,
R4 is hydrogen or an alkyl group having 1 to 6 carbon atoms,
R5 is hydrogen or an optionally substituted hydrocarbyl group having 1 to 22 carbon atoms and
A is an alkylene group having two or three carbon atoms,
into a fluid comprising gas, water and oil under conditions prone to the formation of gas hydrates,
wherein the N,N-dialkyl-ammoniumalkyl fatty acid amide represented by formula (I) is produced by the aminolysis of an ester of a fatty acid and a C1- to C4-alcohol with an N,N-dialkylamino alkyl amine and subsequent neutralization with a carboxylic acid.-
