Composition comprising:
- a) at least one organic sulphide, optionally in oxide form, of general formula (1):
- in which R is chosen from a linear or branched alkyl radical containing from 1 to 4 carbon atoms, and a linear or branched alkenyl radical containing from 2 to 4 carbon atoms;
- n is equal to 0, 1 or 2;
- x is an integer chosen from 0, 1, 2, 3 or 4, R′ is chosen from a linear or branched alkyl radical containing from 1 to 4 carbon atoms, and a linear or branched alkenylene radical containing from 2 to 4 carbon atoms or, only when n=x=0, a hydrogen atom;
- and
- b) at least one odour-masking agent comprising at least one monoester, at least one di- and/or triester, at least one alcohol, at least one ketone and, optionally, at least one terpene.
