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: R1—S—R2, wherein R1 and R2, identical or different, represent: an alkyl radical comprising 1 to 4 carbon atom; or R1 and R2 together with the sulfur 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) the alkyl radicals of which comprise 1 to 12 carbon atoms, preferably 1 to 8: 0.001 parts by weight of at least compound (III) inhibiting polymerization of the alkyl acrylates (II).
