1. A process for preparing fatty acid alkyl esters comprising:
i) forming a mixture comprising a fat-containing feedstock, an alcohol and a sulfonated fatty acid derivative of the formula (I) or a salt thereof: wherein: n is an integer between 0 and 7, m is an integer between 0 and 17, R is hydrogen or methyl, R1 is hydrogen or C1-C6 alkyl, ii) allowing the mixture in step i) to react so as to produce a mixture comprising fatty acid alkyl esters; iii) isolating the fatty acid alkyl esters obtained in step ii).
