Abstract: Use of a composition comprising a base formulation of one or more alkyl esters of a C6-C16 carboxylic acid or mixtures thereof as a fuel composition is provided. The use of the fuel composition is specifically provided for use as a lamp fuel, a lighter fuel, and/or a fuel for cooking, heating or cooling. Specifically, use of a composition as a lamp fuel is provided, wherein the composition comprises by weight 35-45% C8 methyl esters, 25-35% C10 methyl esters, 15-25% C12 methyl esters, and/or 5-15% C14 methyl esters. Also provided is a method for producing a fuel composition comprising the steps of a) providing a vegetable oil, b) preparing alkyl esters of carboxylic acids comprised in said vegetable oil by esterification and/or transesterification, c) optionally isolating one or more of said alkyl esters of said carboxylic acids, wherein said alkyl esters of carboxylic acids comprised in said vegetable oil and/or said one or more isolated alkyl esters constitute said fuel composition.
