The invention concerns a composition for use in particular as odorant of a gas fuel, more particularly of natural gas, comprising: 0.1 to 49.9 particles by weight of at least one alkyl sulphur (I) of formula: R<1>-S-R<2>, wherein R<1> and R<2>, identical or different, represent: an alkyl radical comprising 1 to 4 carbon atoms; or R<1> and R<2> together with the sulphur atom to which they are bound represent a saturated or unsaturated ring including 3 to 5 carbon atoms, optionally substituted by a C1-C4 alkyl or C1-C4 alkenyl; 50 to 99.8 parts by weight of at least two alkyl acrylates (II) thealkyl radicals of which comprise 1 to 12 carbon atoms, preferably 1 to 8; 0.001-0.1 parts by weight of at least one compound (III) inhibiting polymerization of the alkyl acrylates (II).
