A pro-fragrance composition includes a cucurbituril in complex with a fragrance molecule and use of the compositions in counteracting malodour. The cucurbituril is present as a mixture, wherein the mixture includes at least two different cucurbiturils selected from CB[5], CB[6], CB[7] and CB[8]. The complexed fragrance molecule is released when the composition is exposed to a stimulus. Also provides methods for the preparation of pro-fragrance complexes of cucurbiturils and fragrance molecules.
