A malodor counteracting composition contains a malodor counteractant that is capable of neutralizing a malodor and a stabilizer that is capable of decreasing or preventing self-polymerization of the malodor counteractant. The malodor counteractant has a backbone and one or more reactive end groups that are covalently attached to the backbone, the backbone has a molecular weight of 100 to 50,000 Daltons, and the one or more reactive end groups each have an α,β-unsaturated carbonyl group. Also disclosed are consumer, industrial or textile products containing the malodor counteracting composition and methods of neutralizing malodor using the composition.
