    • A malodour-counteracting composition comprising (i) a salt of general formula (I) R 1 R 2 R 3 R 4 N + X' wherein R 1 , R 2 , R 3, R 4 are independently selected from C 1-4 alkyl, or R 1 , R 2 , R 3, R 4 may together constitute a nitrogen-containing cyclic system in which the nitrogen is part of a pyridinium or an iraidazolinium ring; and X' is a counterion characterised by its protonated form having an acidity constant (pKa) lying between 1 and 6; and (ii) an alpha, beta-unsaturated carbonyl compound of the general formula R 5 R 6 C=CR 7 C(=O)YR 8 (II) wherein R 5 , R 6 , R 7 and R 8 are independently selected from hydrogen and C 1-10 hydrocarbyl residues which may be saturated, unsaturated, aromatic, cyclic, branched or unbranched, and are optionally substituted, or R 5 , R 6 , R 7 and R 8 may together constitute a cyclic system and Y is oxygen or a single covalent bond, with the proviso that Y is a covalent bond when R 8 is hydrogen. The composition may be incorporated, into consumer products and is able to remove malodours from the air or from surfaces.
